Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, and in particular to a pulse backflushing dust collector for a mineral powder processing workshop. Background Technology

[0002] Pulse jet dust collector technology originated from improvements to address the low cleaning efficiency and high energy consumption of traditional dust collection equipment. Early dust collectors (such as mechanical vibrating and reverse-jet types) required shutdown for cleaning or relied on continuous airflow for backflushing, leading to production interruptions and severe wear on filter bags. In the 1960s, compressed air pulse cleaning technology was proposed, which uses the instantaneous release of high-pressure gas to create a reverse shock wave, achieving online cleaning of filter bags.

[0003] In the prior art, for example, Chinese Patent No. CN221452002U discloses a pulse back-flushing device for a dust collector, including a housing with a cover plate fixedly installed on the top of the housing; a dust removal mechanism is arranged inside the housing; a pulse back-flushing mechanism is arranged on the housing; the dust removal mechanism includes a connecting frame; the connecting frame is fixedly installed on the inner wall of the housing; a plurality of filter bags are fixedly installed on the connecting frame; the pulse back-flushing mechanism includes two roller supports and a cylinder; the two roller supports are respectively fixedly installed on the inner wall of the housing. This pulse back-flushing device for a dust collector reduces the number of back-flushing pipes and pulse back-flushing valves used by moving the back-flushing pipe, and the filter bags can be easily removed and installed by manually moving the back-flushing pipe during dust collector maintenance without disassembling the back-flushing pipe, thus reducing the operating cost and maintenance workload of the dust collector.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are as follows: Although it can reduce the number of back-flushing pipes and pulse back-flushing valves by moving the back-flushing pipes, and the filter bags can be easily removed and installed by manually moving the back-flushing pipes during dust collector maintenance, thus reducing the cost of dust collector operation and maintenance workload, some dust blown off the surface of the filter bags will be scattered inside the housing during pulse back-flushing of the filter bags. It takes a certain amount of time to clean all the dust on the surface of the filter bags. During this process, the supply of mineral powder-containing gas to the housing needs to be stopped, which leads to a decrease in the filtration efficiency of the mineral powder-containing gas. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that, although it can reduce the number of back-flushing pipes and pulse back-flushing valves by moving the back-flushing pipe, and the filter bags can be easily disassembled and installed by simply moving the back-flushing pipe manually when maintaining the dust collector, thus reducing the cost of dust collector use and the workload of dust collector maintenance, some dust blown off the surface of the filter bags will be scattered inside the housing when pulse back-flushing the filter bags. It takes a certain amount of time to clean all the dust on the surface of the filter bags. During this process, it is necessary to stop supplying the gas containing mineral powder into the housing, which leads to a decrease in the filtration efficiency of the gas containing mineral powder.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a pulse jet dust collector for a mineral powder processing workshop, comprising: a housing, and further comprising:

[0007] Partition 1 is fixedly connected to the inner wall of the box near the top. Multiple filter bags are fixedly connected at equal intervals to the bottom of Partition 1. Partition 2 is fixedly connected to the inner wall of the box and is fixedly connected to Partition 1. A square groove is opened on one side of Partition 2. A rotating rod is rotatably connected to the opposite side of the inner wall of the square groove. A movable plate is fixedly connected to the outer surface of the rotating rod. An L-shaped plate is fixedly connected to one side of the box. A motor is fixedly connected to one side of the L-shaped plate. The output end of the motor is fixedly connected to one end of the rotating rod. Two sets of movable pulse backflushing structures are provided above Partition 1.

[0008] Preferably, two rubber sealing rings are symmetrically fixedly connected to the outer surface of the movable plate, and the rotating rod is rotatably connected to the box body.

[0009] Preferably, two guide rods are symmetrically fixedly connected to opposite sides of the inner wall of the box near the top, and T-shaped plates are slidably connected to the outer surfaces of the two guide rods. Both sets of pulse backflushing structures are fixedly connected to the T-shaped plates.

[0010] Preferably, a lead screw is rotatably connected to the opposite side of the box near the top, and the lead screw is threadedly connected to the T-shaped plate.

[0011] Preferably, a second motor is fixedly connected to the other side of the housing near the top, and the output end of the second motor is fixedly connected to one end of the lead screw.

[0012] Preferably, a U-shaped tube is fixedly connected to the opposite side of the box near the bottom, and a connecting pipe is fixedly connected to the outer surface of the U-shaped tube. The connecting pipe, the U-shaped tube and the box are connected in communication. Solenoid valves are fixedly connected to the inner walls of the U-shaped tube near both ends of the box.

[0013] Preferably, two collection frames are slidably connected to opposite sides of the box near the bottom, and a handle is fixedly connected to one side of each collection frame.

[0014] Preferably, an air outlet pipe is fixedly connected to the top of the box, and the air outlet pipe is connected to the box.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. This utility model, through the controller, controls the motor to start, causing its output shaft to drive the rotating rod to rotate, simultaneously driving the movable plate and rubber sealing ring to rotate 90 degrees, so that they rotate into the inside of the square groove, achieving a certain degree of sealing and forming two dust removal chambers. At the same time, the controller controls the solenoid valve on the side of the dust removal chamber that needs to be cleaned to close, so that the other dust removal chamber can continuously supply mineral powder-containing gas into the housing through the connecting pipe and U-shaped pipe. In this way, when the mineral powder on the surface of multiple filter bags is shaken off, it will only float in one dust removal chamber and will not enter the other dust removal chamber, thus eliminating the need to stop supplying mineral powder-containing gas into the housing, thereby improving the filtration efficiency of mineral powder-containing gas.

[0017] 2. This utility model uses a controller to start a second motor, causing its output shaft to drive a lead screw to rotate. Then, with the screw and T-shaped plate connected by threads and with the guide rod limiting and guiding the T-shaped plate, the T-shaped plate can move to one side along the outer surface of the screw, simultaneously moving the pulse back-blowing structure above multiple filter bags. This aligns the multiple back-blowing pipes of the pulse back-blowing structure with the multiple filter bags. The controller then controls the operation of the pulse back-blowing structure, causing compressed gas to be sprayed instantaneously from the back-blowing pipes into the interior of the filter bags, shaking off the mineral powder on the surface of the filter bags. This allows for simultaneous cleaning of multiple filter bags, thereby improving the efficiency of filter bag surface cleaning. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Examples, such as Figure 1-5 As shown, this utility model provides a pulse backflushing dust collector for a mineral powder processing workshop, including: a housing 1, and further including: a partition 106, which is fixedly connected to the inner wall of the housing 1 near the top. Multiple filter bags 107 are fixedly connected at equal intervals to the bottom of the partition 106. A partition 2 108 is fixedly connected to the inner wall of the housing 1. The partition 2 108 is fixedly connected to the partition 1 106. A square groove 109 is opened on one side of the partition 2 108. A rotating rod 202 is rotatably connected to the opposite side of the inner wall of the square groove 109. A movable plate 203 is fixedly connected to the outer surface of the rotating rod 202. An L-shaped plate 2 is fixedly connected to one side of the housing 1. A motor 201 is fixedly connected to one side of the L-shaped plate 2. The output end of the motor 201 is fixedly connected to one end of the rotating rod 202. Two sets of movable pulse backflushing structures 303 are arranged above the partition 106.

[0028] Furthermore, such as Figure 1-5 As shown, two rubber sealing rings 204 are symmetrically fixedly connected to the outer surface of the movable plate 203. The rotating rod 202 is rotatably connected to the box 1. The rubber sealing rings 204 provide a certain sealing effect.

[0029] Furthermore, such as Figure 1-5As shown, two guide rods 304 are symmetrically fixedly connected to opposite sides of the inner wall of the box 1 near the top. T-shaped plates 302 are slidably connected to the outer surfaces of the two guide rods 304. Both sets of pulse backflushing structures 303 are fixedly connected to the T-shaped plates 302. With the above arrangement, the T-shaped plates 302 can slide along the outer surface of the guide rods 304.

[0030] Furthermore, such as Figure 1-5 As shown, a lead screw 301 is rotatably connected to the opposite side of the box 1 near the top. The lead screw 301 is threadedly connected to the T-shaped plate 302. With the cooperation of the threaded connection between the lead screw 301 and the T-shaped plate 302, and with the cooperation of the guide rod 304 to limit and guide the T-shaped plate 302, when the lead screw 301 rotates, the T-shaped plate 302 can move to one side along the outer surface of the lead screw 301.

[0031] Furthermore, such as Figure 1-5 As shown, a motor 3 is fixedly connected to the other side of the housing 1 near the top. The output end of the motor 3 is fixedly connected to one end of the lead screw 301. The motor 3 is started by the controller, so that its output shaft drives the lead screw 301 to rotate.

[0032] Furthermore, such as Figure 1-5 As shown, a U-shaped tube 102 is fixedly connected to the opposite side of the bottom of the box 1. A connecting pipe 105 is fixedly connected to the outer surface of the U-shaped tube 102. The connecting pipe 105, the U-shaped tube 102 and the box 1 are connected. Solenoid valves are fixedly connected to the inner walls of the U-shaped tube 102 near both ends of the box 1. With the above settings, when the solenoid valve is open, the gas containing mineral powder can enter the interior of the box 1 through the connecting pipe 105 and the U-shaped tube 102 in sequence. When the solenoid valve is closed, the gas containing mineral powder can be prevented from entering the box 1.

[0033] Furthermore, such as Figure 1-5 As shown, two collection frames 103 are slidably connected to opposite sides of the bottom of the housing 1. A handle 104 is fixedly connected to one side of the collection frame 103. The collection frame 103 facilitates the collection of mineral powder shaken off the surface of the filter bag 107, and the handle 104 facilitates the removal of the collection frame 103.

[0034] Furthermore, such as Figure 1-5 As shown, an exhaust pipe 101 is fixedly connected to the top of the box 1. The exhaust pipe 101 is connected to the box 1, and the exhaust pipe 101 facilitates the discharge of clean gas.

[0035] Working principle: In use, when pulse backflushing cleaning of filter bags 107 is required, the controller starts motor 3, causing its output shaft to drive the lead screw 301 to rotate. Then, with the threaded connection between the lead screw 301 and the T-shaped plate 302, and with the guide rod 304 limiting and guiding the T-shaped plate 302, the T-shaped plate 302 can move to one side along the outer surface of the lead screw 301, simultaneously driving the pulse backflushing structure 303 to move above multiple filter bags 107, so that the multiple backflushing pipes of the pulse backflushing structure 303 and multiple... For each filter bag 107, the pulse backflushing structure 303 is existing technology and will not be described in detail. The controller then controls the operation of the pulse backflushing structure 303, causing compressed gas to be instantly ejected from the backflushing pipe into the interior of the filter bag 107, shaking off the mineral powder on the surface of the filter bag 107. This allows for simultaneous cleaning of multiple filter bags 107, thereby improving the efficiency of surface cleaning. When multiple filter bags 107 need cleaning, the controller starts the motor 201, causing its output shaft to drive the rotating rod 2. 02 rotates, synchronously driving the movable plate 203 and rubber sealing ring 204 to rotate 90 degrees, so that they rotate into the inside of the square groove 109, achieving a certain degree of sealing and forming two dust removal chambers. At the same time, the controller controls the solenoid valve on the side of the dust removal chamber that needs to be cleaned to close, so that the other dust removal chamber can continuously supply mineral powder-containing gas into the housing 1 through the connecting pipe 105 and U-shaped pipe 102. In this way, when the mineral powder on the surface of multiple filter bags 107 is shaken off, it will only be in one of the dust removal chambers. The gas floats internally and will not enter another dust removal chamber, thus eliminating the need to stop supplying the gas containing mineral powder to the interior of housing 1, thereby improving the filtration efficiency of the gas containing mineral powder. Once all the mineral powder on the surface of the filter bags 107 has been cleaned, the movable plate 203 can be returned to its initial position, connecting the two dust removal chambers and allowing the gas containing mineral powder to fully contact the filter bags 107. The mineral powder is filtered through the filter bags 107, and the clean gas passes through the filter bags 107 to the top of the partition 106, and finally is discharged through the exhaust pipe 101.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
