Description

Technical Field

[0001] This solution belongs to the field of circulation devices, and specifically relates to a material slurry conveying pump mechanical seal circulation device. Background Art

[0002] The material slurry conveying pump adopts mechanical seal, and the mechanical seal cooling water generally adopts a one-way high-pressure water replenishment method. Once the sealing effect is not good, the material slurry leaks, which will affect the heat dissipation effect of the entire system and the company's production. Under normal circumstances, the cooling water is directly discharged, resulting in serious waste of water resources.

[0003] In actual production, the filter press area employed a total of 20 pumps, all of which used a parallel, single-pass, high-pressure water replenishment system for their mechanical seal cooling water. Approximately 220 m³ of new water was added daily (24 hours a day), resulting in significant water waste. Furthermore, after the replenishment water exited the pump seal, it entered the production solution system, causing system expansion and complicating solution safety. This often resulted in excess solution bubbling into the pool and tank. By recycling the mechanical seal cooling water, water resources were fully utilized, the amount of water entering the production solution system was reduced, and the total volume of the entire production solution system was controlled, ensuring solution safety.

[0004] However, in the prior art, the connections between the mechanical seal water inlet pipe and the mechanical seal water outlet pipe of the mechanical seal circulation device of the material slurry conveying pump and the circulating water tank are easily broken after long-term use. At the same time, when the water level inside the circulating water tank is insufficient and water is added, impurities will enter the circulating water tank. Utility Model Content

[0005] The purpose of this solution is to provide a mechanical seal circulation device for a material slurry conveying pump to solve the problem that the mechanical seal water inlet pipe, the mechanical seal water outlet pipe and the connection between the circulating water tank of the material slurry conveying pump mechanical seal circulation device are easy to break after long-term use. At the same time, when the water level inside the circulating water tank is insufficient and water is added, impurities will enter the circulating water tank.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a material slurry conveying pump mechanical seal circulation device, including a circulating water tank, the upper end of the circulating water tank is fixedly connected to a first flange, the interior of the first flange is connected to a breathing valve by a thread, the upper part of the circulating water tank is fixedly connected to a second flange, the interior of the second flange is connected to a magnetic flap level gauge by a thread, the magnetic flap level gauge passes through the circulating water tank and is slidably connected to the circulating water tank, the interior of the circulating water tank is slidably connected to a filter cover, the filter cover is provided with a cleaning mechanism, the upper end of the circulating water tank is connected to a plum blossom steel cover by a thread, the interior of the circulating water tank is slidably connected to a support ring, the support ring and the filter cover are slidably connected, a compression spring is provided inside the circulating water tank, the lower end of the circulating water tank is provided with an organically sealed water inlet pipe, the lower end of the circulating water tank is provided with an organically sealed water outlet pipe, and the ends of the mechanically sealed water inlet pipe and the mechanically sealed water outlet pipe are both provided with stainless steel ball valves.

[0007] The principle of this solution is that when in use, water is fed into the circulating water tank through the mechanical seal water inlet pipe and water is discharged through the mechanical seal water outlet pipe. The torsion spring is set to protect the connection between the mechanical seal water inlet pipe, the mechanical seal water outlet pipe and the circulating water tank to avoid bending and breaking of the mechanical seal water inlet pipe and the mechanical seal water outlet pipe. When the water level in the circulating water tank is low, the plum blossom steel cover is opened and water is filtered into the circulating water tank through the filter cover. When water is added, the water flow impacts the blades, causing the support shaft to rotate, and then the square rod drives the scraper to move through the slip ring, scratching the filter cover, making it easy to clean impurities attached to the filter cover, and avoiding clogging of the filter cover when water is fed in.

[0008] The technical effect of this solution is that: by setting the torsion spring, the connection between the mechanical seal water inlet pipe, the mechanical seal water outlet pipe and the circulating water tank is protected to prevent the mechanical seal water inlet pipe and the mechanical seal water outlet pipe from bending and breaking.

[0009] When adding water, the water flow impacts the blades, causing the support shaft to rotate, and then the square rod drives the scraper to move through the slip ring, scraping the filter cover, making it easier to clean the impurities attached to the filter cover and avoiding clogging of the filter cover when water is added.

[0010] Furthermore, a guide block is fixedly connected to the surface of the filter cover, and the guide block is slidably connected to the circulating water tank. By providing the guide block, the movement of the filter cover is guided.

[0011] Furthermore, a sliding ball is fixedly connected to the upper end of the filter cover, and the sliding ball contacts the plum blossom steel cover. By arranging the sliding ball, the friction between the plum blossom steel cover and the filter cover is reduced.

[0012] Furthermore, one end of the compression spring contacts the circulating water tank, and the other end of the compression spring is fixedly connected to the support ring. By arranging the compression spring, the support ring is easy to reset.

[0013] Furthermore, a torsion spring is provided on the outside of the mechanical seal water inlet pipe and the mechanical seal water outlet pipe, and the upper end of the torsion spring is fixedly connected to the circulating water tank. By providing the torsion spring, the mechanical seal water inlet pipe and the mechanical seal water outlet pipe are protected.

[0014] Furthermore, the cleaning mechanism includes a support shaft, which is mounted inside the filter housing via a sealed bearing. A blade is fixedly connected to the surface of the support shaft. A square rod is fixedly connected to the support shaft, and a baffle is fixedly connected to the upper end of the square rod. A slip ring is slidably connected to the outer side of the square rod, and a spring is provided on the outer side of the square rod. A scraper is fixedly connected to the surface of the slip ring, and the scraper is slidably connected to the filter housing. When water is added, the water impacts the blade, causing the support shaft to rotate, which in turn causes the square rod to drive the scraper via the slip ring, scraping the filter housing, making it easier to clean impurities attached to the filter housing and preventing clogging of the filter housing when water is added.

[0015] Furthermore, one end of the spring is fixedly connected to the baffle, and the other end of the spring is fixedly connected to the slip ring. By arranging the spring, the slip ring is pressed downward. BRIEF DESCRIPTION OF THE DRAWINGS
