Description

Technical Field

[0001] This utility model relates to the field of reactor feeding technology, and in particular to a feeding and dust removal device for reactors. Background Technology

[0002] Reactors are commonly used equipment in industries such as chemical and pharmaceutical manufacturing. When feeding materials into a reactor, manual or mechanical methods are typically required. This feeding process generates a large amount of dust, which not only pollutes the working environment and affects the health of operators, but also poses a potential dust explosion hazard.

[0003] In actual use, existing feeding devices often lack effective dust removal measures. For example, the lack of a good sealing structure during material feeding causes a large amount of dust to escape into the external environment.

[0004] At the same time, there are no dedicated dust collection components to collect and treat the generated dust, which makes the dust spread in the feeding area and difficult to clean. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a feeding and dust removal device for a reaction vessel, which overcomes the shortcomings of the prior art and effectively solves the problem of the lack of effective dust removal measures in the feeding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A feeding and dust removal device for a reactor includes a feeding cylinder, a feeding frame welded to one side of the outer wall of the feeding cylinder, and a sealing plate hinged to the top outer wall of the feeding frame. A cylinder is hinged between the sealing plate and the feeding frame.

[0008] An exhaust pipe is installed through the top outer wall of the feeding cylinder, and a blower is fixedly connected to the top outer wall of the exhaust pipe via a flange. An air collecting plate is welded to the bottom outer wall of the exhaust pipe, and filter elements are installed at equal intervals on the bottom outer wall of the air collecting plate.

[0009] The filter element is equipped with a pulse nozzle inside, and an annular tube is welded to the outer wall of the top of the pulse nozzle.

[0010] Preferably, a backflush pipe is fixedly connected to one side of the outer wall of the annular pipe, and a gas tank is installed on the outer wall of one end of the backflush pipe. An electromagnetic pulse valve is installed on the outer wall of the backflush pipe.

[0011] Preferably, a gas supply pipe is fixedly connected to the outer wall of the bottom of the gas tank, and a one-way valve is installed on the outer wall of the gas supply pipe.

[0012] Preferably, the bottom outer wall of the feeding cylinder is fixedly connected to the feeding hopper via a flange, and the bottom outer wall of the feeding hopper is welded with a screw feeder.

[0013] Preferably, the screw feeder includes a conveying pipe welded to the outer wall of the bottom of the feeding hopper, a conveying motor fixedly connected to the outer wall of one end of the conveying pipe by screws, and a screw auger fixedly connected to the output shaft of the conveying motor by a coupling.

[0014] Preferably, the reactor body is installed at the end of the screw feeder away from the feed hopper.

[0015] Preferably, an installation plate is welded to one outer wall of the feeding cylinder, and the gas cylinder is installed on the inner wall of the installation plate.

[0016] Preferably, a handle is installed on one side of the outer wall of the sealing plate, and the filter element is located inside the feeding cylinder.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. The feeding and dust removal device for the reactor designed in this paper has a sealing structure consisting of a feeding frame, a sealing plate and a cylinder. When feeding, the cylinder can drive the sealing plate to open, which facilitates the feeding of materials. After feeding is completed, the cylinder drives the sealing plate to close, which seals the feeding port and effectively prevents dust from escaping from the feeding port into the external environment, thus solving the problem of dust escaping due to poor sealing.

[0019] 2. The dust removal device for the reactor designed in this paper utilizes a dust removal system consisting of an extraction pipe, a blower, a collection plate, and a filter element. The blower draws air out of the feeding cylinder through the extraction pipe, creating a negative pressure that draws the dust generated during the feeding process into the feeding cylinder. After being filtered by the filter element, the dust is retained in the feeding cylinder, and the clean air is discharged through the extraction pipe. This achieves effective collection and treatment of dust, solving the problem of dust diffusion caused by the lack of dust removal components.

[0020] 3. The dust removal device for the reactor designed in this paper utilizes a pulse backwash structure composed of a pulse nozzle, an annular pipe, a backwash pipe, an air tank, and an electromagnetic pulse valve. When the filter element may become clogged with dust after a period of use, the electromagnetic pulse valve opens, and the compressed air in the air tank enters the pulse nozzle through the backwash pipe and the annular pipe, and then sprays out from the pulse nozzle to backwash and clean the filter element, thus maintaining the filter element's good filtration performance and solving the problem of filter element clogging affecting the dust removal effect.

Detailed Implementation

[0027] 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.

[0028] Reference Figure 1-5 Example 1: A feeding and dust removal device for a reactor includes a feeding cylinder 1, a feeding frame 2 welded to one side of the outer wall of the feeding cylinder 1, a sealing plate 3 hinged to the top outer wall of the feeding frame 2, a cylinder 4 hinged between the sealing plate 3 and the feeding frame 2, a handle installed on one side of the outer wall of the sealing plate 3, and a filter element 8 located inside the feeding cylinder 1.

[0029] The feeding cylinder 1 is used to contain and handle dust, and the feeding frame 2 provides a specific area for material input. The extension and retraction movement of the cylinder 4 enables the sealing plate 3 to open and close the feeding frame 2, thereby controlling the opening and closing of the feeding port. The handle on one side of the sealing plate 3 makes it convenient for operators to manually operate the sealing plate 3.

[0030] In this embodiment, by setting a sealing structure consisting of a feeding frame 2, a sealing plate 3, and a cylinder 4, when feeding is performed, the cylinder 4 can drive the sealing plate 3 to open, facilitating the feeding of materials. After feeding is completed, the cylinder 4 drives the sealing plate 3 to close, thereby sealing the feeding port and effectively preventing dust from escaping from the feeding port into the external environment, thus solving the problem of dust escaping due to poor sealing.

[0031] In Example 2, an exhaust pipe 5 is installed through the top outer wall of the feeding cylinder 1, and a blower 6 is fixedly connected to the top outer wall of the exhaust pipe 5 via a flange. An air collecting plate 7 is welded to the bottom outer wall of the exhaust pipe 5, and filter elements 8 are installed at equal intervals on the bottom outer wall of the air collecting plate 7.

[0032] The exhaust pipe 5 is used to extract air and dust from the feeding cylinder 1. The blower 6 provides power for the exhaust, creating a negative pressure inside the feeding cylinder 1. The air collecting plate 7 can evenly guide the extracted air and dust to each filter element 8. The filter element 8 filters the air and leaves the dust inside the feeding cylinder 1.

[0033] In this embodiment, a dust removal system consisting of an extraction pipe 5, a blower 6, an air collecting plate 7, and a filter element 8 is used. The blower 6 extracts air from the feeding cylinder 1 through the extraction pipe 5, creating a negative pressure. This causes the dust generated during the feeding process to be sucked into the feeding cylinder 1. After being filtered by the filter element 8, the dust is retained in the feeding cylinder 1, and the clean air is discharged through the extraction pipe 5. This achieves effective collection and treatment of dust, solving the problem of dust diffusion caused by the lack of dust removal components.

[0034] In embodiment 3, a pulse nozzle 9 is provided inside the filter element 8, and an annular tube 10 is welded to the outer wall of the top of the pulse nozzle 9. A backflush tube 11 is fixedly connected to one side of the outer wall of the annular tube 10, and an air tank 12 is installed on the outer wall of one end of the backflush tube 11. An electromagnetic pulse valve 13 is installed on the outer wall of the backflush tube 11. An air supply tube 14 is fixedly connected to the outer wall of the bottom of the air tank 12, and a one-way valve 15 is installed on the outer wall of the air supply tube 14. An installation plate 19 is welded to one side of the outer wall of the feeding cylinder 1, and the air tank 12 is installed on the inner wall of the installation plate 19.

[0035] The pulse nozzle 9 is used to backwash and clean the filter element 8. The annular pipe 10 enables compressed air to be evenly distributed to each pulse nozzle 9. The backwash pipe 11 delivers compressed air from the air tank 12 to the annular pipe 10. The air tank 12 is used to store compressed air. The electromagnetic pulse valve 13 controls the on / off of compressed air. The air replenishment pipe 14 is used to replenish the compressed air in the air tank 12. The one-way valve 15 prevents compressed air from flowing back.

[0036] In this embodiment, using the pulse backwash structure composed of pulse nozzle 9, annular pipe 10, backwash pipe 11, air tank 12 and electromagnetic pulse valve 13, when the filter element 8 may be clogged by dust after a period of use, the electromagnetic pulse valve 13 opens, and the compressed air in the air tank 12 enters the pulse nozzle 9 through the backwash pipe 11 and annular pipe 10, and then sprays out from the pulse nozzle 9 to backwash and clean the filter element 8, so that the filter element 8 maintains good filtration performance and solves the problem of filter element 8 clogging affecting dust removal effect.

[0037] The bottom outer wall of the feeding cylinder 1 is fixedly connected to the feeding hopper 16 by a flange, and the bottom outer wall of the feeding hopper 16 is welded with a screw feeder 17. The screw feeder 17 includes a conveying pipe welded to the bottom outer wall of the feeding hopper 16, a conveying motor fixedly connected to the outer wall of one end of the conveying pipe by screws, and a screw auger fixedly connected to the output shaft of the conveying motor by a coupling. The end of the screw feeder 17 away from the feeding hopper 16 is equipped with the reactor body 18.

[0038] The feeding hopper 16 is used to collect the filtered material in the feeding cylinder 1. The screw feeder 17 includes a conveying pipe, a conveying motor and a screw conveyor. The conveying motor drives the screw conveyor to rotate and convey the material through the conveying pipe to the reactor body 18. The reactor body 18 is used to receive the conveyed material for reaction.

[0039] Working Principle: When feeding material into the reactor body 18, cylinder 4 is first activated, driving the sealing plate 3 to open. The operator then feeds the material into the feeding cylinder 1 through the feeding frame 2. After feeding is completed, cylinder 4 drives the sealing plate 3 to close, sealing the feeding port. Next, blower 6 is activated, drawing air out of the feeding cylinder 1 through the extraction pipe 5, creating a negative pressure inside the feeding cylinder 1. Dust generated during feeding is drawn into the feeding cylinder 1, filtered by the filter element 8, and remains inside the feeding cylinder 1. Clean air is discharged through the extraction pipe 5. The filtered material falls into the feeding hopper 16. Then, the conveyor motor is activated, driving the auger to rotate through the coupling, conveying the material through the conveying pipe into the reactor body 18 for reaction.

[0040] After a period of use, filter element 8 may become clogged with dust, affecting its filtration performance. At this time, the electromagnetic pulse valve 13 opens, and compressed air in the air tank 12 enters the pulse nozzle 9 through the backwash pipe 11 and the annular pipe 10, and then sprays out from the pulse nozzle 9 to backwash and clean the filter element 8, restoring its filtration performance.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
