Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment, and in particular to an automatic water supply mechanism for a dust removal device. Background Technology

[0002] The concept of green, low-carbon, and sustainable development has been widely promoted in the pharmaceutical industry in recent years. In the production of traditional Chinese medicine preparations, the use of key production equipment such as powder mixers and oscillating granulators generates dust. To ensure emissions meet relevant requirements, a double-tower dust collector has been installed on the roof of the company's pharmaceutical production workshop. Its functions are twofold: first, to reduce vent blockage after dust removal; and second, to prevent dust pollution of the environment.

[0003] The equipment works by using a spray system for dust removal. When pharmaceutical production is underway in the workshop, the equipment is activated, utilizing the interaction between water and dust-laden gas—that is, when dust particles encounter water droplets, processes such as wetting, agglomeration, and diffusion occur, thus achieving dust removal. The spray system and dust removal equipment operate intermittently (activated inside the workshop when needed), but the water supply system requires personnel to go to the top floor to open a manual ball valve, resulting in continuous water intake and wasting water resources, which is inconvenient for management. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic water supply mechanism for a dust removal device to solve the above-mentioned problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic water supply mechanism for a dust removal device includes a water storage tank and a spray water pump. The inlet of the spray water pump is connected to a water pump inlet pipe, which extends into the water storage tank. The water storage tank is connected to a water tank inlet pipe. A pneumatic angle seat valve and a manual ball valve are sequentially installed on the water tank inlet pipe. A water level upper and lower limit detection probe is also installed in the water storage tank, as well as a fully automatic water level controller. The water level upper and lower limit detection probe is electrically connected to the fully automatic water level controller, and the pneumatic angle seat valve is also electrically connected to the fully automatic water level controller.

[0006] As a preferred technical solution, a two-position five-way valve is also provided between the pneumatic angle seat valve and the fully automatic water level controller.

[0007] As a preferred technical solution, the water level upper and lower limit detection probe includes a probe at point A, a probe at point B, and a probe at point C, from top to bottom.

[0008] As a further preferred technical solution, an overflow pipe is installed at a horizontal position higher than the probe at point A.

[0009] As a further preferred technical solution, a drain pipe is also provided at the bottom of the water storage tank, and a drain valve is provided on the drain pipe.

[0010] As a further preferred technical solution, the overflow pipe and the sewage pipe are combined.

[0011] As a preferred technical solution, the pneumatic angle seat valve is made of stainless steel.

[0012] Compared with existing technologies, the advantages of this invention are as follows: With this structure, the dual-tower dust collector can control the pneumatic angle seat valve via upper and lower water level detection probes, regardless of whether it is running or stopped, thereby achieving automatic water replenishment and cessation. This improves work efficiency, saves water, solves the problem of frequent manual operation of valves by going up and down stairs, avoids water waste, and achieves the goals of improving efficiency, saving costs, and reducing the accident rate.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] Example:

[0019] See Figure 1 and Figure 2An automatic water supply mechanism for a dust removal device includes a water storage tank 6 and a spray pump 7. The inlet of the spray pump 7 is connected to a water pump inlet pipe 8, which extends into the water storage tank 6. The water storage tank 6 is connected to a water tank inlet pipe 9. A pneumatic angle seat valve 2 and a manual ball valve 1 are sequentially installed on the water tank inlet pipe 9. A water level upper and lower limit detection probe 5 and a fully automatic water level controller 4 are also installed in the water storage tank 6. The water level upper and lower limit detection probe 5 are electrically connected to the fully automatic water level controller 4, and the pneumatic angle seat valve 2 is also electrically connected to the fully automatic water level controller 4. A two-position five-way valve 3 is also installed between the pneumatic angle seat valve 2 and the fully automatic water level controller 4.

[0020] In this embodiment, the pneumatic angle seat valve 2 is DN15 and is made of stainless steel; the fully automatic water level controller 4 is a DF-9A model purchased from Shanghai Zhuoyi Electronics Co., Ltd.

[0021] The pneumatic angle seat valve 2 is installed at the rear end of the manual ball valve 1. The two-position five-way valve 3 and the fully automatic water level controller 4 are installed in the power distribution box. The upper and lower limit water level detection probe 5 is installed in the water storage tank 6 with an opening at the top. The pneumatic angle seat valve 2 is installed on the water inlet pipe 9 of the water tank. The operator only needs to open the manual ball valve 1 and turn on the power when going to work, and close the manual ball valve 1 and the power when leaving work. There is no need to frequently switch it on and off by going up and down the stairs in between.

[0022] The structure of the water level upper and lower limit detection probe 5 is as follows: Figure 3 As shown, the device includes probes at points A, B, and C from top to bottom. The specific fabrication and installation method is as follows: A PTFE mounting plate 51 with a diameter of 80mm is fabricated. The three probes 52 (A, B, and C) are respectively installed on this plate. A 15mm protruding wiring terminal 53 is used for wiring, and a waterproof cover 54 is fitted onto the wiring terminal. An opening is made at the top of the water tank 6, and the probe is vertically installed inside the tank. Probe A (as the upper limit detection probe) is located at the top of the water tank 6 (below the overflow outlet of the overflow pipe 10). When the water level rises to the level of probe A... At point B, when water contacts the probe, the fully automatic water level controller 4 automatically closes the pneumatic angle seat valve 2 to stop water intake; point B is the lower limit water level control point, with the probe contact located at the bottom of the water storage tank 6 (100mm from the bottom); point C is the common end, forming a loop with points A and B, located at the lowest point of the water storage tank 6; when the water level in the water storage tank 6 is lower than point B, the pneumatic angle seat valve 2 starts to work and lifts to automatically replenish water; when the water level in the water storage tank 6 keeps contacting the probe at point A, the pneumatic angle seat valve 2 closes, stopping water intake, and this process is continuously implemented to achieve automatic water intake and automatic water stoppage;

[0023] A drain pipe 11 is also provided at the bottom of the water storage tank 6, and a drain valve 12 is provided on the drain pipe 11; the overflow pipe 10 and the drain pipe 11 merge.

[0024] Figure 2 In the diagram, a represents the water source direction and b represents the air source direction. Water enters the water storage tank 6 through the water tank inlet pipe 9, and then enters the spray pump 7 through the water pump inlet pipe 8. The water usage points of the equipment are inside the air ducts that enter and exit the water storage tank 6. Each air duct has two sets of spray heads 13. The air ducts are connected to the fan 14. After opening the manual ball valve 1, water will continuously enter. The water entry and stop are automatically controlled by the two-position five-way valve 3, the fully automatic water level controller 4, and the water level upper and lower limit detection probe 5.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
