Description

Technical Field

[0001] The utility model relates to the technical field of ore bin dust removal equipment, and more specifically to an intelligent dust removal device for a tin smelting ore bin. Background Art

[0002] In the tin smelting process, the ore materials need to be transported to the ore bin by means of transportation, and then lifted by a crane into the ore bin hopper. Since the ore materials are mostly soft powder, a large amount of dust is generated during the unloading and lifting process, forming a radioactive dust source.

[0003] In the prior art, nozzles are usually installed around the ore bin or fog cannons are used. The water mist shell formed by increasing the water pressure suppresses the diffusion of dust particles and achieves the purpose of dust reduction. However, due to the limited coverage area of the traditional spraying method, it cannot reduce dust. In such a harsh working environment, it causes harm to the occupational health of operators and is very likely to cause occupational diseases such as pneumoconiosis. The ore dust materials fly in the air and are not easy to be recovered. In such a harsh working environment, the driver's vision is reduced, which is very likely to cause safety accidents.

[0004] Therefore, how to provide an intelligent dust removal device for tin smelting ore bin that can realize automatic water replenishment and automatically adjust the water spray pressure according to the dust concentration is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0005] In view of this, the utility model provides an intelligent dust removal device for a tin smelting ore bin, aiming to solve the above technical problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An intelligent dust removal device for a tin smelting ore bin, installed in the ore bin, including a water supply system and a spray system;

[0008] A plurality of columns are fixed on both sides of the ore bin, and two parallel tracks are fixed on the tops of the plurality of columns located on both sides of the ore bin, and a crane is slidably connected to the top surfaces of the two tracks;

[0009] The water replenishment system comprises a water tank and a water replenishment pipe, wherein the water tank is fixed on the plurality of columns on one side of the ore bin and on the wall facing the center side of the ore bin, and one end of the water replenishment pipe is connected to the inner cavity of the water tank, and the other end is connected to the water source;

[0010] The described spraying system includes a pressure pump, a spray pipe, and spray nozzles. The pressure pump is fixed at one end of the bottom surface of the overhead crane, and its water inlet end is connected to the water storage tank through a suction pipe; the spray pipe is perpendicular to the traveling direction of the overhead crane and is fixed to its bottom surface, with one end closed and the other end connected to the water outlet end of the pressure pump; the spray nozzles are fixed on the outer wall of the spray pipe and communicate with its inner cavity.

[0011] The beneficial effects of the above technical solution are that water is replenished into the water storage tank through a water pump and a make-up water pipe. The pressure pump sucks the water in the water storage tank and sends it to the spray pipe, and the spray pipe sprays water into the ore bin through the spray nozzles to reduce dust.

[0012] Preferably, a make-up water controller is fixed on the outer wall surface of the column corresponding to one side of the water storage tank and located at the outermost end to control the opening and closing of the water pump at the water source. The make-up water controller controls the opening and closing of the water pump at the water source to replenish water into the water storage tank.

[0013] Preferably, the water storage tank is a long strip-shaped box body, and its length direction is parallel to the length direction of the track. The top surface of the water storage tank is open, and the end of the suction pipe away from the pressure pump extends into the inner cavity of the water storage tank. The top surface of the water storage tank is set to be open. When the overhead crane is moving, the suction pipe can slide along the inner cavity of the water storage tank with one end of the overhead crane, ensuring that the overhead crane can draw water from the water storage tank at any time during the movement process to perform omnidirectional spraying and dust reduction in the ore bin.

[0014] Preferably, a water level sensor is fixed on the inner wall of the water storage tank, and the water level sensor is electrically connected to the make-up water controller.

[0015] Preferably, a make-up water solenoid valve is fixed on the make-up water pipe, and the make-up water solenoid valve is electrically connected to the make-up water controller.

[0016] The beneficial effects of the above technical solution are that the water level sensor can monitor the water level in the water storage tank. When the water level in the water storage tank is too low, the make-up water controller controls the make-up water solenoid valve to open to automatically replenish water to the water storage tank.

[0017] Preferably, a spray controller is fixed in the cab of the overhead crane, and the spray controller is electrically connected to the pressure pump. The spray controller can control the pressure pump to draw water from the water storage tank to spray and reduce dust in the ore bin.

[0018] Preferably, a dust detector is fixed on the outer wall at the bottom end of the cab of the overhead crane, and the dust detector is electrically connected to the spray controller. The dust detector can detect the dust concentration in the ore bin and feedback the signal to the spray controller.

[0021] Preferably, the distance between two adjacent nozzles is not greater than 80 cm, and the distance between the nozzle and the bottom surface of the overhead crane is not less than 1 m. This ensures that the sprayed water fully covers the entire bin and guarantees the dust reduction effect.

[0022] As can be seen from the above technical solutions, compared with the prior art, the present utility model discloses an intelligent dust removal device for a tin smelting ore bin. The water replenishing system automatically replenishes water according to the water level in the water storage tank, and the spray system automatically adjusts the water spraying pressure according to the dust concentration. When the dust concentration of the ore materials in the ore bin exceeds the set value, the dust detector detects the dust concentration information of the ore materials and transmits the dust concentration information of the ore materials to the control box of the spray system. The control box of the spray system controls the pressure pump to automatically adjust the spray pressure according to the detected dust concentration and sprays water on the ore bin, thereby achieving the technical effect of automatically controlling the spray.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to the attached Figures 1 to 6 , the embodiments of the present utility model disclose an intelligent dust removal device for a tin smelting bin, which is installed in the bin, can automatically supply water and spray, and can automatically adjust the spray pressure to comprehensively reduce dust in the bin and protect the health of the operators in the bin. It includes a water supply system and a spray system;

[0032] A plurality of columns 7 are fixed on both sides of the bin. At the top of the plurality of columns 7 on both sides of the bin, two parallel tracks 8 are fixed. A crane 1 is slidably connected to the top surfaces of the two tracks 8;

[0033] The water supply system includes a water storage tank 6 and a water supply pipe 3.

[0034] A water supply controller 2 is fixed on the outer wall of the column 7 corresponding to one side of the water storage tank 6 and located at the outermost end to control the opening and closing of the water pump at the water source.

[0035] A water level sensor 5 is fixed on the inner wall of the water storage tank 6, and the water level sensor 5 is electrically connected to the water supply controller 2.

[0036] A water supply solenoid valve 4 is fixed on the water supply pipe 3, and the water supply solenoid valve 4 is electrically connected to the water supply controller 2.

[0050] The dust removal device provided by this embodiment can achieve automatic spraying and dust reduction at any time through automatic control, ensuring the physical health of the personnel working in the bunker and the safe operation of the overhead crane driver, and avoiding safety accidents caused by the excessive dust concentration in the bunker affecting the driver's line of sight.
