Integrated pulse jet apparatus for sinter plate dust collector

Abstract

This utility model discloses an integrated pulse jet cleaning device for a sintered plate dust collector, including a cylinder housing. Multiple fixed tubes are fixedly installed on the rear side of the cylinder housing. Connecting tubes are movably connected to the rear side of each fixed tube. Four connecting rods are fixedly installed inside each fixed tube. Fixed rods are fixedly installed at the ends of the connecting rods. Four fixing rod grooves are provided on the outer surface of each fixing rod. Rotating plates are rotatably installed inside each fixing rod groove, and the rotating plates are all in contact with the inner surface of the connecting tubes. This utility model uses the elastic force of a bending spring to drive the rotating plates to rotate towards the inner wall of the fixed tubes, thereby pushing the connecting tubes into one side of the fixed tubes. This ensures that the connecting tubes are tightly against the inner wall surface of the fixed tubes, preventing gas leakage due to gaps between the connecting tubes and the fixed tubes.

Description

Technical Field

[0001] This utility model relates to the field of pulse jet cleaning technology, specifically to an integrated pulse jet cleaning device for sintering plate dust collectors. Background Technology

[0002] Pulse jet cleaning devices are mainly used in bag filters. They utilize changes in gas pressure to spray compressed gas from the air tank (air distribution box) into the air chamber of the bag filter, causing solid dust adhering to the filter material to detach, thus achieving the purpose of cleaning or collection. They are a key component of bag filters and are widely used in dust control and collection in various industries.

[0003] Existing pulse jet cleaning devices for sintered plate dust collectors typically use welded structures for installation. This leads to insufficient precision after pulse valve installation, resulting in air leakage or uneven stress that damages the grinding discs. Furthermore, leaks are prone to occur at the connection points of the air inlet pipe. Therefore, these devices do not meet current requirements. To address this, we propose an integrated pulse jet cleaning device for sintered plate dust collectors. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated pulse jet cleaning device for sintered plate dust collectors, in order to solve the problems mentioned in the background art, such as the pulse jet cleaning device for sintered plate dust collectors usually adopting a welded structure for installation, which leads to insufficient precision after pulse valve installation, resulting in air leakage or uneven force causing damage to the grinding disc, and the connection of the air inlet pipe is prone to leakage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated pulse jet cleaning device for a sintered plate dust collector, comprising a cylinder housing, a plurality of fixed pipes fixedly installed on the rear side of the cylinder housing, a connecting pipe movably connected to the rear side of each fixed pipe, four connecting rods fixedly installed inside each fixed pipe, a fixed rod fixedly installed at the end of each connecting rod, four fixed rod outer grooves provided on the outer surface of each fixed rod, a rotating plate rotatably installed inside each fixed rod outer groove, and each rotating plate fitting against the inner surface of the connecting pipe.

[0006] Preferably, a rotating shaft is fixedly installed at one end of each rotating plate, and the rotating shaft rotates and engages with the inner groove of the fixing rod.

[0007] Preferably, a bending spring is movably installed between the rotating plate and the inner groove of the fixed rod, and an elastic arc plate is fixedly installed at the outer end of the rotating plate, and the elastic arc plate is in contact with the inner wall surface of the connecting pipe.

[0008] Preferably, the cylinder housing has multiple air jet ports on its front side, and the fixed pipe is connected to each air jet port. A pulse valve is provided between the air jet port and the fixed pipe, and the surface of the pulse valve is provided with a valve diaphragm.

[0009] Preferably, both ends of the cylinder housing are provided with communication ports, and the bottom end of the cylinder housing is provided with an air inlet.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model, through the cooperation of a rotating plate and a bending spring, allows the device to be used so that the elastic force of the bending spring drives the rotating plate to rotate towards the inner wall of the fixed tube. This causes the rotating plate to push the connecting tube into the inside of the fixed tube, making the connecting tube tightly adhere to the inner wall surface of the fixed tube, thus preventing gas leakage caused by gaps between the connecting tube and the fixed tube.

[0012] 2. By setting up an elastic arc plate, when there is a large size difference between the connecting pipe and the fixed pipe, the connecting pipe can be inserted into one side of the fixed pipe and squeezed by the elastic arc plate, so that the connecting pipe is stuck in the inner surface of the fixed pipe in a trumpet shape. The elastic arc plate squeezes the surface of the connecting pipe, thereby avoiding the situation where the surface of the connecting pipe arches up and a gap appears between it and the inner wall of the fixed pipe after the connecting pipe is inserted into the fixed pipe.

[0013] 3. This utility model, through the cooperation of the cylinder housing and the valve diaphragm, enables the device to ensure accurate valve installation by using a high-precision cylinder housing in conjunction with a high-precision pulse valve. Furthermore, the valve diaphragm seals the fixing pipe and the air jet port to prevent air leakage. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 4 An embodiment of this utility model provides an integrated pulse jet cleaning device for a sintered plate dust collector, comprising a cylinder housing 1, a plurality of fixed pipes 3 fixedly installed on the rear side of the cylinder housing 1, a connecting pipe 4 movably connected to the rear side of each fixed pipe 3, four connecting rods 8 fixedly installed inside each fixed pipe 3, a fixed rod 7 fixedly installed at the end of each connecting rod 8, four fixed rod outer grooves 9 provided on the outer surface of the fixed rod 7, and a rotating plate 10 rotatably installed inside each fixed rod outer groove 9, the rotating plate 10 being in contact with the inner surface of the connecting pipe 4.

[0021] By cooperating with the rotating plate 10 and the bending spring 12, the device can be driven by the elastic force of the bending spring 12 to rotate towards the inner wall of the fixed tube 3 during use. This causes the rotating plate 10 to push the connecting tube 4 into the inside of the fixed tube 3, making the connecting tube 4 fit tightly against the inner wall surface of the fixed tube 3, thus preventing gas leakage caused by gaps between the connecting tube 4 and the fixed tube 3.

[0022] One end of each rotating plate 10 is fixedly equipped with a rotating shaft 11, which rotates and engages with the inner groove 9 of the fixed rod.

[0023] A bending spring 12 is movably installed between the rotating plate 10 and the inner groove 9 of the fixed rod. An elastic arc plate 13 is fixedly installed at the outer end of the rotating plate 10. The elastic arc plate 13 is in contact with the inner wall surface of the connecting pipe 4.

[0024] With the setting of the elastic arc plate 13, when the size difference between the connecting pipe 4 and the fixed pipe 3 is large, the connecting pipe 4 can be inserted into one side of the fixed pipe 3 and squeezed by the elastic arc plate 13, so that the connecting pipe 4 is stuck in the inner surface of the fixed pipe 3 in a trumpet shape. The elastic arc plate 13 squeezes the surface of the connecting pipe 4, thereby avoiding the situation where the surface of the connecting pipe 4 arches up and a gap appears between it and the inner wall of the fixed pipe 3 after the connecting pipe 4 is inserted into the fixed pipe 3.

[0025] The cylinder housing 1 has multiple air jets 2 on its front side, and the fixed pipes 3 are all connected to the air jets 2. A pulse valve is provided between the air jets 2 and the fixed pipes 3, and the surface of the pulse valve is provided with a valve diaphragm 6.

[0026] By cooperating with the cylinder housing 1 and the valve diaphragm 6, the device can ensure the accurate installation position of the valve through the high-precision cylinder housing 1 and the high-precision pulse valve. The valve diaphragm 6 seals the fixed pipe 3 and the jet port 2 to prevent air leakage.

[0027] Both ends of the cylinder housing 1 are provided with connecting ports 5, and the bottom end of the cylinder housing 1 is provided with an air inlet.

[0028] During use, the integrated pulse jet cleaning device for sintered plate dust collectors can be driven by the elastic force of the bending spring 12 to rotate the rotating plate 10 towards the inner wall of the fixed tube 3. This causes the rotating plate 10 to push the connecting pipe 4 into the inner wall of the fixed tube 3, ensuring that the connecting pipe 4 is tightly pressed against the inner wall surface of the fixed tube 3. This prevents gas leakage caused by gaps between the connecting pipe 4 and the fixed tube 3.

[0029] When there is a large size difference between the connecting pipe 4 and the fixed pipe 3, the connecting pipe 4 can be inserted into one side of the fixed pipe 3 and squeezed by the elastic arc plate 13, so that the connecting pipe 4 is funnel-shaped and stuck on the inner surface of the fixed pipe 3. The elastic arc plate 13 also squeezes the surface of the connecting pipe 4, thereby preventing the surface of the connecting pipe 4 from arching and creating a gap between it and the inner wall of the fixed pipe 3 after it is inserted into the fixed pipe 3.

[0030] By using a high-precision cylinder housing 1 in conjunction with a high-precision pulse valve, the valve installation position is ensured to be accurate, and the valve diaphragm 6 is used to seal the fixed pipe 3 and the jet port 2 to prevent air leakage.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
