Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air pipe cleaning, in particular to a novel intermittent arsenic reduction tank air pipe cleaning device. BACKGROUND

[0002] In the production of arsenic by wet process, sulfur dioxide is used to reduce arsenic crystallization to realize the valuable recovery of arsenic, but because the reaction in the SO2 air pipe is violent during the reduction process, after the reduction is completed and the gas is stopped, the air pipe is quickly blocked by crystallization. Therefore, after the reduction of each tank is completed, the air pipe must be cleaned.

[0003] However, manual cleaning is currently commonly used, which requires entering the air pipe for operation, which not only consumes a lot of physical strength and time, but also causes fatigue and discomfort of the operator due to the poor working environment. In addition, the leakage risk of sulfur dioxide and arsenic trioxide is very high during the cleaning process. If it is leaked into the air and inhaled by the operator, it may cause poisoning and even casualties.

[0004] Therefore, a novel intermittent arsenic reduction tank air pipe cleaning device is proposed to solve the above problems. CONTENT OF THE UTILITY MODEL

[0005] The problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a novel air pipe cleaning device to solve the problem of high labor intensity and the risk of poisoning and casualties caused by the leakage of sulfur dioxide and arsenic trioxide during manual cleaning.

[0006] To achieve the above purpose, the present specification provides a novel intermittent arsenic reduction tank air pipe cleaning device, which comprises an arsenic reduction tank body and an air pipe, the outer side wall of the arsenic reduction tank body is fixedly connected with a communication pipe which is in communication therewith, the air pipe is vertically installed to the top of the communication pipe, and the air pipe is in communication with the communication pipe, a cleaning mechanism is installed at one end of the communication pipe away from the arsenic reduction tank body, and the inner wall of the communication pipe is fixedly connected with a limiting block.

[0007] The cleaning mechanism comprises a gas cylinder, a movable rod, a connecting column and a drill bit, the movable rod is slidingly installed in the gas cylinder, the connecting column is rotatably connected with the end of the movable rod, the drill bit is fixed to the end of the connecting column, and a spiral groove matched with the limiting block is formed in the outer side wall of the connecting column.

[0008] The cleaning mechanism is configured to clean the arsenic scaling of the communication pipe, the movable rod, the connecting column, the drill bit and the communication pipe are coaxially arranged, and the movable rod, the connecting column and the drill bit all extend into the inner cavity of the communication pipe.

[0009] Furthermore, the cleaning mechanism also includes a second connecting flange, which is fixed to one end of the cylinder. The end of the connecting pipe away from the arsenic reduction tank is fixedly connected to a first connecting flange, and the second connecting flange is connected to the first connecting flange.

[0010] Furthermore, multiple scrapers are fixedly connected to the outer wall of the connecting column, and the multiple scrapers are distributed at equal intervals.

[0011] Furthermore, a retaining ring is fixedly connected to the outer perimeter of the connecting column, and the outer diameter of the retaining ring is the same as the inner diameter of the connecting pipe.

[0012] Furthermore, the drill bit is made of TA2 material.

[0013] Furthermore, a support frame is fixedly connected to the outer wall of the arsenic reduction tank, and the support frame is fixedly connected to the cylinder.

[0014] The beneficial effects of this application are as follows: This application provides a novel intermittent arsenic reduction tank duct cleaning device. By utilizing the telescopic movement of a cylinder combined with the movement of the connecting column in the spiral groove, it not only achieves the linear movement of the connecting column but also its rotational movement. This composite movement allows the drill bit to penetrate deep into the connecting pipe for efficient cleaning of stubborn arsenic scale. In addition, the scraper design can scrape off residual arsenic scale on the inner wall of the connecting pipe, effectively removing even tiny particles attached to the pipe wall. The retaining ring ensures that the scraped arsenic scale can be pushed and discharged, preventing secondary accumulation of arsenic scale. This achieves comprehensive cleaning of the inner wall of the connecting pipe. By replacing manual cleaning with automated cleaning, it reduces the risk of operators coming into contact with toxic substances, reduces the possibility of poisoning and injury caused by sulfur dioxide and arsenic trioxide leaks, and improves workplace safety.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a partial embodiment of the present utility model, and not all embodiments.

[0023] Please see Figures 1-4 A novel intermittent arsenic reduction tank duct cleaning device includes an arsenic reduction tank body 1 and a duct 3. A connecting pipe 2 is fixedly connected to the outer wall of the arsenic reduction tank body 1. The duct 3 is vertically installed to the top of the connecting pipe 2 and is connected to the connecting pipe 2. A cleaning mechanism 5 is installed at the end of the connecting pipe 2 away from the arsenic reduction tank body 1, and a limiting block 7 is fixedly connected to the inner wall of the connecting pipe 2.

[0024] The cleaning mechanism 5 includes a cylinder 51, a movable rod 53, a connecting column 54, and a drill bit 55. The movable rod 53 is slidably installed inside the cylinder 51. The connecting column 54 is rotatably connected to the end of the movable rod 53. The drill bit 55 is fixed to the end of the connecting column 54. The outer wall of the connecting column 54 is provided with a spiral groove 56 that matches the limiting block 7.

[0025] The cleaning mechanism 5 is configured to clean the arsenic scale on the connecting pipe 2. The movable rod 53, the connecting column 54, the drill bit 55 and the connecting pipe 2 are all coaxially arranged, and the movable rod 53, the connecting column 54 and the drill bit 55 all extend into the inner cavity of the connecting pipe 2.

[0026] This solution is used to clean the rapid crystallization inside the air duct and prevent blockage. By controlling the cylinder 51, the movable rod 53 and the connecting column 54 at one end can be extended and retracted. Specifically, by intermittently starting the cylinder 51, the movable rod 53 and the connecting column 54 are driven to extend and retract. During the movement of the connecting column 54, the cooperation between the limiting block 7 and the spiral groove 56 can provide guidance for the connecting column 54, so that the connecting column 54 moves and rotates at the same time, thereby driving the drill bit 55 to rotate synchronously and clean the stubborn arsenic scale accumulated in the connecting pipe 2.

[0027] The connecting pipe 2 is fixed to the outer wall of the arsenic reduction tank 1 by welding.

[0028] It should be noted that cylinder 51 adopts existing technology and can realize DCS control of solenoid valve ventilation by connecting to DI and DO lines, adding sequential control interlocking program, and realizing automatic cleaning of sulfur dioxide air duct of arsenic reduction tank by instrument operation when the reduction ends.

[0029] Please see Figure 2 The cleaning mechanism 5 also includes a second connecting flange 52, which is fixed to one end of the cylinder 51. The end of the connecting pipe 2 away from the arsenic reduction tank 1 is fixedly connected to a first connecting flange 6, and the second connecting flange 52 is connected to the first connecting flange 6.

[0030] In this embodiment, connecting flange 2 52 is connected to connecting flange 1 6 by bolts and nuts. In addition, sealing gaskets are installed at the ends of connecting flange 2 52 and connecting flange 1 6 that are close to each other, so as to seal and prevent the leakage of sulfur dioxide and arsenic trioxide.

[0031] Please see Figure 4 Multiple scraper blades 58 are fixedly connected to the outer wall of the connecting column 54. The multiple scraper blades 58 are evenly distributed. A retaining ring 57 is also fixedly connected to the outer perimeter of the connecting column 54. The outer diameter of the retaining ring 57 is the same as the inner diameter of the connecting pipe 2.

[0032] In this embodiment, the connecting column 54 rotates while moving, thereby using the scraper 58 to clean the arsenic scale remaining on the inner wall of the connecting pipe 2. In addition, the baffle ring 57 is provided and abuts against the inner wall of the connecting pipe 2, which can push the arsenic scale scraped off by the scraper 58 to achieve the cleaning purpose, while avoiding the impact of arsenic scale on the spiral groove 56.

[0033] Please see Figure 4 Drill bit 55 is made of TA2 material.

[0034] Please see Figure 1 A support frame 4 is fixedly connected to the outer wall of the arsenic reduction tank 1, and the support frame 4 is fixedly connected to the cylinder 51.

[0035] In this embodiment, the support frame 4 is provided to support the cleaning mechanism 5 and ensure the stable operation of the cylinder 51.

[0036] Working principle: By periodically activating cylinder 51, the movable rod 53 and the connecting column 54 at one end extend and retract. During the movement of the connecting column 54, the cooperation between the limiting block 7 and the spiral groove 56 provides guidance for the connecting column 54, thereby enabling the connecting column 54 to rotate while moving, which in turn drives the drill bit 55 to rotate synchronously, cleaning the stubborn arsenic scale accumulated in the connecting pipe 2. When the connecting column 54 moves and rotates, the scraper 58 cleans the arsenic scale remaining on the inner wall of the connecting pipe 2. In addition, the set retaining ring 57, which abuts against the inner wall of the connecting pipe 2, can push the arsenic scale scraped off by the scraper 58 to achieve the cleaning purpose.

[0037] 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. Equivalent substitutions or changes made according to the technical solution and the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
