Устройство для зарядки регенеративных патронов

Номер: RU0000192740U1
Автор: Хворостинин Александр Геннадьевич, Чишков Николай Николаевич
Принадлежит: Общество с ограниченной ответственностью "ТЕХНИКА СПАСЕНИЯ"

Полезная модель служит для набивки патронов регенеративного респиратора поглотителем, в том числе поглотителем химическим известковым (ХП-И), и может применяться в аварийно - спасательных подразделениях военной, морской, горной, химической, нефтяной, металлургической и других отраслях с вредными производствами, в которых применяются респираторы изолирующие. Технический результат - обеспечение практического обеспылевания рабочего пространства вокруг устройства при одновременном повышении качества поглотителя и, тем самым, качества газо-воздушной смеси, вдыхаемой человеком. Для этого устройство для зарядки регенеративных патронов содержит герметично закрывающийся бункер для сыпучего материала, расположенные под ним сепаратор материала и зарядную емкость для связи ее с патроном, виброплиту для регенеративных патронов и систему пылеотсоса со сборником пыли. Система пылеотсоса выполнена с возможностью отсоса пыли от сепаратора и из патрона в сборник пыли, который снабжен фильтром, механизм обеспечения вибрации виброплиты связан с сепаратором и выполнен с возможностью регулировки амплитуды вибрации. 1 ил.

An exhaust purification system for a working machine reliably issues filter regeneration warnings to the operator, prompting manual regeneration, so that damage to the DPF device can be avoided. When a PM estimate becomes higher than a given value, a screen displays a warning message prompting manual regeneration. If the warning message fails to prompt the operator to perform manual regeneration and reference time t has passed since the display of the warning message, a speaker outputs a first warning sound. When the operator notices the first warning sound and turns on a regeneration switch, regeneration control is started. If the operator fails to notice the first warning sound and reference time t passes, the speaker instead outputs a second warning sound louder than the first warning sound.

An apparatus for cleaning air filters utilizes a pressurized fluid flow, preferably air, to rotate a set of air spraying jets inside a hollow interior of a filter in order to remove particles from the filter. To ensure proper positioning of the jets in relation to the filter the present invention uses a set of plates with slots and pins, wherein the pins secure the apparatus on one end of the filter. The set of plates also at least partially blocks the flow of air out of the ends to more efficiently direct the flow of air from the jets to the filter. The jets then may be moved reciprocated along the length of the filter for cleaning purposes. 1. (canceled)2. (canceled)3. (canceled)4. (canceled)5. (canceled)6. (canceled)7. (canceled)8.

An apparatus and a method are provided for a heating, ventilation, and air conditioning (HVAC) home air filter to remove airborne molecular contaminants and volatile organic compounds (VOCs) from air within residential spaces. The HVAC home air filter comprises a supportive frame having a shape and size suitable to orient the HVAC home air filter within a residential HVAC system. A filter medium is retained within the supportive frame to remove the airborne molecular contaminants and VOCs from air flowing through the residential HVAC system. The filter medium comprises a combination of media layers configured to exhibit a relatively high filtration efficiency and a low air pressure drop across the filter medium. The supportive frame comprises a plurality of elongate sections and corner sections disposed along perimeter edges of the filter medium to support the filter medium within the residential HVAC system so as direct air through the filter medium. 1.

The present disclosure provides an exemplary process for a system that may remove particulate from industrial water fluids using a Particulate Removal System (PRS). In some aspects, this system may treat water pulled from different Industrial Fluid Systems (IFS) while doing continuous monitoring and quality tests of the water. In some embodiments, the system may use sensors and other technology to allow for the system to periodically self-clean itself allowing for maximum efficiency and accuracy while also cleaning the water from the IFS. In some implementations, the water from the IFS may be filtered through a Particulate Trap Mechanism (PTM) to ensure that particulate including dissolved material has been removed from the water and separated from possible contamination throughout the system. In some aspects the system may be used for continuous and direct measurement of water quality and automatic chemical level adjustment by systems to maintain a desired range or setpoints. 1. A particulate removal system for continuous fluid sampling in industrial fluid systems , the particulate removal system comprising:a receiving end configured to receive fluid from an industrial fluid system;a plurality of sensors, wherein each of the plurality of sensors is configured to monitor a predefined attribute of fluid received from the industrial fluid system when fluid is flowed in contact with each of the plurality of sensors;at least one fluid actuator controlling flow of fluid from the industrial fluid system to the particulate removal system;an outflow end to expel fluid flowed through the particulate removal system; anda controller in logical communication with one or more of the plurality of sensors and the at least one fluid actuator, wherein the controller controls a position of the at least one fluid actuator.2. The system of claim 1 , further comprising a particulate trap mechanism located between the industrial fluid system and the system for fluid monitoring claim 1 , ...
