Description

Technical Field

[0001] This utility model relates to the technical field of baghouse dust collectors, and specifically to a baghouse dust collector equipped with an exhaust gas utilization device. Background Technology

[0002] A baghouse dust collector is a dry dust filtration device suitable for capturing fine, dry, non-fibrous dust. Dust-laden gas enters the baghouse dust collector through the inlet, and under the action of the fan, the airflow passes through the filter bags. Dust particles are trapped on the outer surface of the filter bags due to inertial collision and interception, while clean gas is discharged through the outlet. When adsorbing dense smoke generated in a factory, the smoke is usually drawn into the baghouse dust collector, and then the impurities are removed before the smoke is released. However, the heat contained in the smoke is not utilized, resulting in waste.

[0003] A search for the above-mentioned problems revealed that among the existing technologies, such as the bag filter with exhaust gas utilization device proposed in CN221601504U, the dust collector draws in dense smoke, intercepts particles and impurities in the smoke through a dust collection bag, and then passes the dense smoke to the other end. The dense smoke is then blown downwards by a fan. A U-shaped tube is installed at the bottom of the device. The dense smoke can heat the water source in the U-shaped tube by contacting it, thereby utilizing the heat of the dense smoke.

[0004] However, the dust collection bags of this device are fixed to the top of the partition, and the dust collection bags do not contact the bottom of the bag filter. When the dense smoke enters the dust collector, not all of the dense smoke can enter the dust collection bags to filter the impurities in the dense smoke. Some dense smoke may flow through the bottom of the dust collection bags, resulting in insufficient filtration of the dense smoke and poor utilization of the dense smoke in subsequent processes. Utility Model Content

[0005] This utility model proposes a bag filter dust collector equipped with an exhaust gas utilization device, which solves the problem in the prior art that when filtering impurity particles in dense smoke, it is difficult for all the dense smoke to enter the collection bag, resulting in incomplete filtration.

[0006] The technical solution of this utility model is as follows:

[0007] A baghouse dust collector equipped with an exhaust gas utilization device includes a dust collection box and a box cover. The dust collection box has an air inlet and an air outlet on its side. The box cover is detachably installed on the top of the dust collection box and has several through holes. The collector also includes a partition plate, an air passage pipe, connecting pipes, dust collection bags, a suction assembly, a bag-pulling assembly, and a sealing assembly. The partition plate is fixedly installed inside the dust collection box. The air passage pipe is fixedly installed inside the dust collection box. Several connecting pipes are connected and installed on the side of the air passage pipe. Several dust collection bags are provided and connected to several connecting pipes. The suction assembly is located on the side of the dust collection box. Several bag-pulling assemblies are provided and located on the box cover for pulling the dust collection bags. The sealing assembly is located on the box cover for sealing the through holes of the box cover.

[0008] Furthermore, the air intake assembly includes an air intake pump, an air intake pipe, and an air outlet pipe. The air intake pump is installed on the side of the dust collection box. The air intake pipe is connected to the air inlet of the air intake pump and to the side of the dust collection box. The air outlet pipe is connected to the air outlet of the air intake pump and to the side of the dust collection box.

[0009] Furthermore, the bag assembly includes an mounting block, a rotating column, a placement block one, and a placement block two. The mounting block is fixedly installed at the rear end of the dust collection bag. The rotating column is rotatably mounted through the dust collection bag and the bottom end of the rotating column is fixedly connected to the top end of the mounting block. The placement block one is fixedly installed on the side of the rotating column, and the placement block two is fixedly installed on the side of the rotating column.

[0010] Furthermore, the sealing assembly includes a fixing plate, a sealing plate, a connecting rod, a fixing rod, and a bolt. Two fixing plates are provided, and the two fixing plates are fixedly installed on the box cover. Threaded holes are provided on the fixing plates. A plurality of sealing plates are provided, and the plurality of sealing plates are slidably installed on the box cover. A plurality of connecting rods are provided, and the plurality of connecting rods are respectively fixedly installed on the plurality of sealing plates. The fixing rods are fixedly installed on the sides of the plurality of connecting rods, and threaded holes are provided on the sides of the fixing rods. The bolts are adapted to the threaded holes.

[0011] Furthermore, when the sealing plate slides to block the through hole of the box cover, the threaded hole of the fixing rod and the threaded hole of the fixing plate are at the same horizontal position.

[0012] Furthermore, the air inlet and outlet of the dust collector are respectively connected to an air inlet pipe and an air outlet pipe, the air inlet pipe is connected to the air passage pipe, and valves are installed on the air inlet pipe and the air outlet pipe.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, the device connects several connecting pipes through the air passage pipe. After the dense smoke enters, it can directly enter the dust collection bag through the air passage pipe, thereby preventing the dense smoke from drifting outside the dust collection bag. The dust collection bag filters the impurity particles in the dense smoke, and the filtered dense smoke drifts out through the dust collection bag.

[0015] 2. In this utility model, when dense smoke enters the dust collection bag, the rear end of the dust collection bag can be pulled up by the bag pulling assembly to prevent the dust collection bag from being placed in a wrinkled position, so that the dense smoke can smoothly enter the dust collection bag. After the dust collection is completed, the impurity particles in the dust collection bag can be shaken by the bag pulling assembly so that they fall into the bottom of the bag, preventing the particles from clogging the filter holes on the side of the dust collection bag.

[0016] In summary, through the cooperation of the dust collection box, box cover, partition plate, air pipe, connecting pipe, dust collection bag, air suction component, bag pulling component and sealing component, this device can ensure that all dense smoke enters the dust collection bag for filtration, thereby preventing some dense smoke from passing through the dust collection bag and making it difficult for it to drift into the dust collection bag.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] like Figures 1-2 As shown, this embodiment proposes a baghouse dust collector equipped with an exhaust gas utilization device, including a dust collection box 1, a box cover 2, and an air inlet and outlet on the side of the dust collection box 1. The box cover 2 is detachably installed on the top of the dust collection box 1 and has several through holes. It also includes a partition plate 3, an air passage pipe 4, a connecting pipe 5, dust collection bags 6, a suction assembly, a bag-pulling assembly, and a sealing assembly. The partition plate 3 is fixedly installed inside the dust collection box 1, the air passage pipe 4 is fixedly installed inside the dust collection box 1, several connecting pipes 5 are provided, and several connecting pipes 5 are connected and installed on the side of the air passage pipe 4. Several dust collection bags 6 are provided, and several dust collection bags 6 are respectively connected to several connecting pipes 5. The suction assembly is located on the side of the dust collection box 1, and several bag-pulling assemblies are provided, and several bag-pulling assemblies are located on the box cover 2 for pulling. The dust collection bag 6 and the sealing assembly are installed on the cover 2 to seal the through holes of the cover 2. Specifically, the air inlet and outlet of the dust collector 1 are respectively connected to the air inlet pipe 7 and the air outlet pipe 8. The air inlet pipe 7 is connected to the air outlet pipe 4, and valves 9 are installed on the air inlet pipe 7 and the air outlet pipe 8. First, the dense smoke passes through the air inlet pipe 7, and then directly enters the dust collection bag 6 for filtration through the air outlet pipe 4 and the connecting pipe 5. After filtration, the filtered dense smoke is sucked into the lower part of the partition plate 3 by the suction assembly, or it can be released through the air outlet pipe 8. During suction, the through holes of the cover 2 can be sealed by the sealing assembly, and the impurities in the dust collection bag 6 can be settled by the bag pulling assembly. When dense smoke is sucked in, the dust collection bag 6 can be straightened to facilitate the entry of dense smoke.

[0026] In this embodiment, reference Figure 3 The air intake assembly includes an air intake pump 101, an air intake pipe 102, and an air outlet pipe 103. The air intake pump 101 is installed on the side of the dust collection box 1. The air intake pipe 102 is connected to the air inlet of the air intake pump 101 and is also connected to the side of the dust collection box 1. The air outlet pipe 103 is connected to the air outlet of the air intake pump 101 and is also connected to the side of the dust collection box 1. Specifically, after the dense smoke is filtered, the air intake pump 101 can be started. It should be noted that the air intake pipe 102 is connected to the top of the partition plate 3, and the air outlet pipe 103 is connected to the bottom of the partition plate 3. The filtered dense smoke is placed under the partition plate 3 through the air intake pipe 102 and then through the air outlet pipe 103 for storage or utilization.

[0027] In this embodiment, reference Figure 4 The dust bag assembly includes a mounting block 201, a rotating column 202, a placement block 1 203, and a placement block 204. The mounting block 201 is fixedly installed at the rear end of the dust collection bag 6. The rotating column 202 is rotatably mounted on the cover 2, and its bottom end is fixedly connected to the top end of the mounting block 201. Placement block 1 203 and placement block 204 are fixedly installed on the side of the rotating column 202. Specifically, when filtering dense smoke, the rotating column 202 can be pulled, causing the mounting block 201 to rotate. The bottom of the dust bag 6 is positioned so that it is in a straight state. It should be noted that the placement block 1 203 is located below the placement block 204. At this time, the bottom of the placement block 1 203 contacts the top of the cover 2, thus providing support. After filtration is completed, the rotating column 202 can be rotated to position the placement block 1 203 at the through hole of the cover 2, causing it to move down and place the placement block 204 in contact with the cover 2, thus providing support. At this time, the bottom of the dust bag 6 sinks down, so that the bottom contacts the partition plate 3, allowing dust particles to fall to the bottom of the dust bag 6 under the action of gravity.

[0028] In this embodiment, reference Figure 5 The sealing assembly includes a fixing plate 301, a sealing plate 302, a connecting rod 303, a fixing rod 304, and bolts 305. Two fixing plates 301 are provided, fixedly mounted on the cover 2, and threaded holes are provided on each fixing plate 301. Several sealing plates 302 are provided, slidably mounted on the cover 2. Several connecting rods 303 are provided, each fixedly mounted on one of the sealing plates 302. The fixing rods 304 are fixedly mounted on the sealing plates 302. The bolts 305 are fitted to the side of several connecting rods 303 and the side of the fixing rod 304 is provided with threaded holes. Specifically, when the sealing plate 302 slides to the through hole of the cover 2 to block it, the threaded hole of the fixing rod 304 and the threaded hole of the fixing plate 301 are at the same horizontal position. Therefore, during filtration, the sealing plate 302 can be moved to the through hole, and then the bolts 305 can be threaded into the threaded holes of the fixing plate 301 and the fixing rod 304 to fix it.

[0029] In this embodiment, when filtering dense smoke, firstly, the rotating column 202 is pulled, causing the mounting block 201 and the rear end of the dust collection bag 6 to rise, so that the dust collection bag 6 is in a straightened state. It can be supported by placing the block 203 in contact with the box cover 2. Then, the sealing plate 302 is slid to the through hole to seal it. The bolt 305 is threaded into the threaded holes of the fixing plate 301 and the fixing rod 304 to fix it. After completion, the dense smoke is introduced into the inlet pipe 7, and directly enters the dust collection bag 6 for filtration through the air pipe 4 and the connecting pipe 5. After filtration, the suction pump 101 is started, and the filtered dense smoke passes through the outlet pipe 101. The vent pipe 103 is placed below the partition plate 3 for storage or use. The valve 9 of the vent pipe 8 can also be opened to release or collect the smoke and move it elsewhere. After collection, the through hole is opened, and the rotating column 202 is rotated so that the first placement block 203 rotates to the through hole. Then the rotating column 202 is moved down so that the rear end of the dust collection bag 6 moves down onto the partition plate 3, so that the impurity particles in the dust collection bag 6 settle to the bottom of the dust collection bag 6. During the settling, the second placement block 204 can be brought into contact with the box cover 2 to support it. The rotating column 202 can also be moved up and down repeatedly to drive the dust collection bag 6 up and down, and the impurity particles are moved down by gravity.

[0030] It should be added that the dust collection belt has filter holes, which are small and can block impurities and allow air to flow out.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
