Description

Technical Field

[0001] The utility model relates to the technical field of circulating pumps, in particular to a vertical chemical circulating pump with anti-leakage function. Background Art

[0002] A circulating pump refers to a pump used to transport the circulating liquid for reaction, absorption, separation, and regeneration of the absorption liquid in a device. The circulating pump mainly consists of components such as a motor and an impeller. By driving the impeller to rotate through the motor, the impeller can drive the transmission medium to rotate, generate centrifugal force to discharge, and pressurize the medium.

[0003] In the existing circulating pumps, since the impeller rotates at a high speed, if the chemical raw materials contain impurities, the impurities will impact the impeller, causing damage to the impeller. The existing circulating pump inlet pipe has no filtering mechanism and cannot filter the impurities in the chemical raw materials. Moreover, after the chemical raw materials are pressurized and discharged, the pressure on the discharge pipe will be very high. After long-term use, it will cause leakage at the discharge pipe, resulting in environmental pollution of the chemical raw materials or personal injury.

[0004] Therefore, aiming at the deficiencies of the existing technology, it is very necessary to provide a vertical chemical circulating pump with anti-leakage function to solve the deficiencies of the existing technology. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a vertical chemical circulating pump with anti-leakage function, avoiding the deficiencies of the existing technology. By setting a leak prevention mechanism in the discharge pipeline of the circulating pump body, the anti-leakage effect of the circulating pump is improved. The filter cover and filter screen set in the anti-leakage mechanism can filter the chemical raw materials in the discharge pipeline, preventing large particles and impurities from damaging the discharge pipeline due to the flow rate and causing leakage. At the same time, the arc-shaped anti-leakage block and rubber sealing block installed at the end of the discharge pipeline are used for anti-leakage and sealing treatment, and the waterproof layer and anti-corrosion layer can perform anti-corrosion and waterproof treatment on the discharge pipeline body to prevent the leakage of chemical materials in the circulating pump.

[0006] The above object of the utility model is achieved by the following technical means.

[0007] Provide a vertical chemical circulating pump with anti-leakage function, including a circulating pump body. A support frame is installed at the bottom of the circulating pump body. Feed pipes and discharge pipes are respectively arranged at both ends of the circulating pump body above the support frame. A leak prevention mechanism and an anti-corrosion mechanism are respectively arranged inside the discharge pipe. The anti-corrosion mechanism includes a waterproof layer and an anti-corrosion layer, and a waterproof layer is arranged between the anti-corrosion layer and the discharge pipe.

[0008] The leak prevention mechanism includes a filter cover. The filter cover is installed at one end of the discharge pipe close to the circulating pump body. A filter screen is arranged inside the filter cover. Hanging ears are arranged at both ends of the filter cover. An arc-shaped anti-leakage block is arranged beside the filter cover. The arc-shaped anti-leakage block is close to the end of the discharge pipe, and a rubber sealing block is arranged at the top of the arc-shaped anti-leakage block.

[0009] Specifically, a limiting ring is arranged inside the discharge pipeline, and the limiting ring cooperates with the hanging ears.

[0010] Specifically, the waterproof layer includes two groups of splicable waterproof shells A and B. A convex block is integrally formed on the waterproof shell A, and a groove matching with the convex block is formed on the waterproof shell B.

[0011] Specifically, the arc-shaped leak-proof block and the rubber sealing block are fitted and installed, and there is a gap between the arc-shaped leak-proof block and the rubber sealing block.

[0012] The utility model improves the leak-proof effect of the circulating pump by arranging a leak-proof mechanism in the discharge pipeline of the circulating pump body. The filter cover and the filter screen arranged in the leak-proof mechanism can filter the chemical raw materials in the discharge pipeline to prevent large particles and impurities from damaging the discharge pipeline due to the flow rate and causing leakage. At the same time, the arc-shaped leak-proof block and the rubber sealing block installed at the end of the discharge pipeline are simultaneously subjected to leak-proof sealing treatment. The waterproof layer and the anti-corrosion layer can perform anti-corrosion and waterproof treatment on the discharge pipeline body to prevent the chemical materials in the circulating pump from leaking.

[0035] The present utility model will be further described in conjunction with the following embodiments.

[0036] Embodiment 1.

[0037] As Figures 1 - 3 shown, a leak-proof vertical chemical circulating pump includes a circulating pump body 1. A support frame 2 is installed at the bottom of the circulating pump body 1. Feed pipes 4 and a discharge pipe 3 are respectively arranged at both ends of the circulating pump body 1 above the support frame 2. Leak-proof mechanisms 5 are respectively arranged inside the discharge pipe 3.

[0038] The circulating pump body 1 is vertically installed through the support frame 2 installed at the bottom. The feed pipe 4 and the discharge pipe 3 arranged at both ends of the circulating pump body 1 are respectively responsible for feeding and discharging chemical raw materials of the circulating pump body 1. At the same time, the leak-proof mechanism 5 arranged inside the discharge pipe 3 can improve the leak-proof and anti-corrosion performance of the discharge pipe 3, and prevent chemical raw materials from leaking during the circulation of the circulating pump body 1.

[0039] The leak-proof mechanism 5 includes a filter cover 7. The filter cover 7 is installed at one end of the discharge pipe 3 close to the circulating pump body 1. A filter screen 8 is arranged inside the filter cover 7. Hanging ears 9 are arranged at both ends of the filter cover 7. An arc-shaped leak-proof block 10 is arranged beside the filter cover 7. The arc-shaped leak-proof block 10 is close to the end of the discharge pipe 3. A rubber sealing block 11 is arranged at the top of the arc-shaped leak-proof block 10.

[0040] When in use, the filter cover 7 in the leak-proof mechanism 5 can filter the discharge pipe 3 on the circulating pump body 1. The filter screen 8 installed in the filter cover 7 can further filter chemical raw materials. The filter cover 7 is hung inside the discharge pipe 3 through the hanging ears 9 arranged at both ends. The arc-shaped leak-proof block 10 and the rubber sealing block 11 arranged at the end of the discharge pipe 3 can perform leak-proof and sealing treatments on the discharge port at the end of the discharge pipe 3, and improve the leak-proof effect during the circulation of the circulating pump body 1.

[0041] A limiting ring 12 is provided inside the discharge pipeline 3. The limiting ring 12 cooperates with the hanging ears 9. The limiting ring 12 provided inside the discharge pipeline 3 can limit and fix the hanging ears 9 on both sides of the filter cover 7, keeping the filter cover 7 stable during the circulation process.

[0042] A waterproof layer 13 and an anti-corrosion layer 14 are provided between the anti-corrosion layer 14 and the discharge pipeline 3. The waterproof layer 13 and the anti-corrosion layer 14 can respectively perform waterproof and anti-corrosion treatments on the discharge pipeline 3 to improve the safety of the plastic pipeline and prevent chemical raw materials from leaking.

[0043] The waterproof layer 13 includes two groups of spliceable waterproof shells A17 and waterproof shells B18. A convex block 15 is integrally formed on the waterproof shell A17, and a groove 16 that cooperates with the convex block 15 is provided on the waterproof shell B18. During the installation process, the convex block 15 on the waterproof shell A17 is installed into the groove 16 on the waterproof shell B18 to achieve a tight fit, and finally the waterproof shell A17 and the waterproof shell B18 are combined into a whole.

[0044] The arc-shaped leak-proof block 10 and the rubber sealing block 11 are fitted together, and there is a gap between the arc-shaped leak-proof block 10 and the rubber sealing block 11. Since the chemical raw materials will generate a certain pressure during the circulation process of the circulation pump body 1, the gap between the arc-shaped leak-proof block 10 and the rubber sealing block 11 installed at the discharge port end of the discharge pipeline 3 of the circulation pump body 1 can be tightly fitted when subjected to pressure, enabling the arc-shaped leak-proof block 10 and the rubber sealing block 11 to achieve a good leak-proof effect.

[0045] During the production process, the leak-proof effect of the circulation pump is improved by setting a leak-proof mechanism in the discharge pipeline 3 of the circulation pump body 1. The filter cover 7 and the filter screen 8 provided in the leak-proof mechanism 5 can filter the chemical raw materials in the discharge pipeline 3 to prevent large particles and impurities from damaging the discharge pipeline 3 due to the flow rate and causing leakage. At the same time, the arc-shaped leak-proof block and the rubber sealing block 11 installed at the end of the discharge pipeline 3 are also subjected to leak-proof sealing treatment. The waterproof layer 13 and the anti-corrosion layer 14 can perform anti-corrosion and waterproof treatments on the discharge pipeline 3 body to prevent the chemical materials in the circulation pump from leaking.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
