Description

Technical Field

[0001] The utility model belongs to the technical field of cooling water circulation, in particular to an automatic cooling water circulation device for a hot water pump mechanical seal. Background Art

[0002] In the prior art, after searching, it was found that a Chinese patent disclosed "A hot water pump mechanical seal cooling water automatic circulation device", and its publication number is "CN219888343U". The patent mainly includes: a water storage tank, a cooling water inlet pipe, a cooling water return pipe, a water supply pipe, a liquid level gauge, a water inlet pump, a drain valve, and a water supply pump; the cooling water inlet pipe and the cooling water return pipe are arranged on the upper side of the water storage tank; the water supply pipe is arranged on the upper side of the water storage tank and is lower than the position of the cooling water inlet pipe and the cooling water return pipe; the liquid level gauge is arranged on the side of the water storage tank for measuring the liquid level in the water storage tank; the water inlet pump is arranged at the inner bottom of the water storage tank for ensuring the required flow and pressure of the cooling water; the water supply pipe is connected to the water supply pump, and the liquid level gauge is electrically connected to the water supply pump for controlling the start and stop of the water supply pump by the liquid level, completing the automatic water supply process, and ensuring the water consumption inside the water storage tank; the drain valve is arranged at the bottom of the water storage tank for timely draining the water storage tank.

[0003] The existing device has an obvious defect in the process of recycling and circulating used cooling water, that is, it does not filter it. Due to the lack of filtration, various impurities originally contained in the water, such as fine mud and sand particles, metal debris, scale, etc., will enter the pipe together with the water without hindrance. As the equipment continues to operate, this situation will continue to repeat. Over time, these impurities will gradually accumulate in the pipe. Due to the continuous accumulation of impurities, the effective flow area of ​​the pipe will become smaller and smaller. When the impurities accumulate to a certain extent, the pipe will be blocked. Once the pipe is blocked, it will have a serious adverse effect on the entire circulation system. On the one hand, it will lead to poor circulation of cooling water, so that the mechanical sealing part cannot be fully and effectively cooled, affecting the normal operation of the equipment. On the other hand, it may increase the load of the circulation pump, increase the operating cost of the equipment, and may even cause damage to the circulation pump, requiring a lot of time and effort to repair and clean.

Impurities, prevent these impurities from entering the subsequent circulation system. When the rotating shaft 399 rotates, the rotating shaft 23 will rotate synchronously with the rotating shaft 399 through the transmission of the two pulleys 3992 and the belt 3993. When the rotating shaft 23 rotates, it drives the cam 24 thereon to rotate. Due to the special shape of the cam 24, it will make the filter plate 22 slide up and down in the two slide grooves 21 on the filter box 1. The up and down sliding of the filter plate 22 can shake off the impurities blocked thereon, avoiding impurities clogging the filter eyes and affecting the filtering effect.

[0029] The configuration mechanism 3 includes a support plate 31 fixedly connected to the back of the filter box 1, a hot water pump 32 is provided on the support plate 31, two L-shaped rods 33 are fixedly connected to the back of the filter box 1, a water outlet pipe 34 is fixedly sleeved on the two L-shaped rods 33, and a plurality of nozzles 35 are fixedly sleeved on the outer wall of the water outlet pipe 34.

The outer wall of the rotating shaft 399 is fixedly sleeved with a fan blade 3991, and the outer walls of the rotating shaft 399 and the rotating shaft 23 are fixedly sleeved with a pulley 3992. The outer walls of the two pulleys 3992 are wrapped with a belt 3993. By setting the configuration Mechanism 3, the water filtered by the filter plate 22 is then filtered by the activated carbon 26. The activated carbon can further filter out fine impurities in the water. The water filtered by the activated carbon enters the cooling pipe 37. In the cooling pipe 37, the water exchanges heat with the coolant in the cooling box 36. The coolant absorbs the heat of the water and cools the water.

The water can be pumped out again by the water pump 392 and used to dissipate heat at the mechanical seal of the hot water pump 32, thereby realizing the recycling of water resources.

[0030] A specific application of this embodiment is as follows: when in use, the motor 398 is started, and the motor 398 drives the rotating shaft 399 to rotate. Since the rotating shaft 399 is connected to the fan blades 3991, the fan blades 3991 rotate synchronously. At the same time, when the fan blades 3991 rotate, air is sucked in from outside the bellows 395. The sucked air is filtered through the filter 396 to remove impurities therein. The filtered air is blown toward the mechanical seal of the hot water pump 32, taking away heat, thereby achieving air cooling and heat dissipation at the mechanical seal. At the same time, the water pump 392 can be started to pump water from the water tank 391. The pumped water is transported to the water outlet pipe 34 through the delivery pipe 393, and then evenly sprayed out from the multiple nozzles 35 on the water outlet pipe 34 to dissipate heat at the mechanical seal of the hot water pump 32, thereby further reducing its temperature; the sprayed water will flow to the filter plate 22, and the filter plate 22 will first filter the water to remove larger impurities to prevent these impurities from entering the subsequent circulation system. As the filter 9 rotates, the shaft 1 23 rotates synchronously with the shaft 399 through the transmission of the two pulleys 3992 and the belt 3993. When the shaft 1 23 rotates, it drives the cam 24 on it to rotate. Due to the special shape of the cam 24, it causes the filter plate 22 to slide up and down in the two chutes 21 on the filter box 1. The up and down sliding of the filter plate 22 can shake off the impurities blocked thereon, preventing the impurities from clogging the filter eyes and affecting the filtering effect. The water filtered by the filter plate 22 is then filtered by the activated carbon 26. The activated carbon can further filter out fine impurities in the water. The water filtered by the activated carbon enters the cooling pipe 37. In the cooling pipe 37, the water exchanges heat with the coolant in the cooling box 36. The coolant absorbs the heat of the water, causing the water to be cooled. The cooled water is collected in the water storage tank 391, thus completing a complete water circulation process. The water can be pumped out by the water pump 392 again to dissipate heat at the mechanical seal of the hot water pump 32, thereby realizing the recycling of water resources.
