Description

Technical Field

[0001] The utility model relates to the technical field of equipment water cooling circulation, and more specifically, to a device for recycling the cooling water of equipment. Background Art

[0002] In the pharmaceutical, chemical, food and manufacturing industries, various equipment will be used during the production process. Most of the equipment involves cooling devices and uses water cooling, which has high efficiency and low cost, and only needs to connect water pipes.

[0003] Currently, when most equipment conducts water cooling, purified water sources are used, resulting in relatively high manufacturing costs. However, the cooled water is usually discharged for treatment, causing a large amount of water resource waste.

[0004] Therefore, how to provide a device for recycling the cooling water of equipment to recycle the water cooled by the equipment and reduce water resource waste is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the utility model provides a device for recycling the cooling water of equipment, aiming to solve the above technical problems.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A device for recycling the cooling water of equipment, comprising:

[0008] A water storage bucket, the top opening of the water storage bucket is connected to a water source through a water inlet pipe, and the bottom is connected to equipment through a water outlet pipe to cool it. A first water pump is fixed on the pipeline of the water outlet pipe to pump the water in the water storage bucket;

[0009] A sedimentation tank, the water inlet of the sedimentation tank is connected to the water outlet of the equipment through a connecting pipe;

[0010] A recovery pipe, one end of the recovery pipe is fixedly connected to the water outlet of the sedimentation tank, and the other end is connected to the top opening of the water storage bucket. A cooling plate is fixed on the pipeline of the recovery pipe.

[0011] The beneficial effects of the above technical solution are as follows: The water storage bucket is connected to the water source to provide cooling water for the equipment. The first water pump extracts the water in the water storage bucket through the water outlet pipe and sends it to the equipment for water cooling. The water after the equipment is cooled may carry residues on the equipment and enter the sedimentation tank for sedimentation and filtration. The water after sedimentation and filtration flows back into the water storage bucket through the recovery pipe to realize the recycling of water. Since heat exchange occurs between the equipment and the water during the water cooling process of the equipment, the temperature of the cooled water rises. During the recovery process, it is cooled by the cooling plate, which not only solves the problem of recycling cooling water but also solves the problem of the too high temperature of the cooling water after heat exchange, ensuring the water cooling effect.

[0012] Preferably, it further includes a second water pump, and the second water pump is fixed on the pipeline of the recovery pipe between the cooling plate and the sedimentation tank to extract the water in the sedimentation tank. The water in the sedimentation tank is extracted and circulated into the water storage bucket by the second water pump.

[0013] Preferably, a filter is detachably connected to the pipeline of the recovery pipe close to the water storage bucket. The filter uses a reverse osmosis membrane to filter the residues in the recycled water, ensuring the cleanliness of the cooling water for the equipment.

[0014] Preferably, the inner cavity of the sedimentation tank is sequentially divided into a first sedimentation chamber, a second sedimentation chamber, and a third sedimentation chamber by a first partition plate and a second partition plate along the length direction. The water inlet is provided at the top of the side wall of the sedimentation tank corresponding to the first sedimentation chamber, and the water outlet is provided at the bottom of the side wall of the sedimentation tank corresponding to the third sedimentation chamber. The sedimentation tank uses a three-stage sedimentation method to sediment and filter the water after cooling, and finally recovers it into the water storage bucket through the third sedimentation chamber.

[0015] Preferably, a first water overflow trough is provided at the top end of the first partition plate, and a second water overflow trough is provided at the top end of the second partition plate. The first water overflow trough and the second water overflow trough are located on the same horizontal plane and are arranged in an alternating manner. The alternately arranged first water overflow trough and second water overflow trough can make the water entering the sedimentation tank flow in an S-shaped manner, improving the sedimentation and filtration effect.

[0016] Preferably, the distance between the water outlet and the bottom wall of the sedimentation tank is not less than 15 mm. There is a certain distance between the water outlet and the bottom wall of the sedimentation tank, and the large-particle residues accumulated at the bottom of the sedimentation tank will not flow into the recovery pipe, improving the cleanliness of the recycled water.

[0017] Preferably, a filter screen is fixed between the second partition plate and the side wall of the sedimentation tank where the water outlet is provided. The filter screen can further filter the water entering the third sedimentation chamber, improving the recovery and filtration effect of the cooling water.

[0018] Preferably, the filter screen is a 100- or 120-mesh filter screen, and the mesh diameter is not greater than 1 mm, ensuring that large particles are isolated and the water finally entering the recovery pipe is free of large residues.

[0019] Preferably, a water replenishing valve is provided on the pipeline of the water inlet pipe, and the water storage bucket is replenished with water by using the water replenishing valve.

[0020] Preferably, a high-level detection sensor is fixed on the outer wall of the top end of the water storage bucket, and a low-level detection sensor is fixed on the outer wall of the bottom end. Both the high-level detection sensor and the low-level detection sensor are electrically connected to the water replenishing valve. The high-level detection sensor and the low-level detection sensor detect the water level in the water storage bucket and feed back signals to the water replenishing valve, and the water storage bucket is replenished with water by opening and closing the water replenishing valve.

By recycling the cooling water, the utilization rate of water is improved and the waste of resources is reduced; through the precipitation and filtration of water, the cleanliness of the recycled water is ensured, and the pollution of the equipment during the water cooling process of the equipment is avoided, resulting in an increase in the unqualified rate of equipment production; the recycled water is cooled by the cooling plate to prevent the temperature of the recycled water from being too high and reducing the water cooling effect.

Detailed implementation mode

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention. Embodiment 1:

[0030] See attached Figure 1 ~3. An apparatus for recycling cooling water of equipment is disclosed in the embodiments of the present invention. By sedimenting, filtering and recycling the water after cooling the equipment, the utilization rate of water resources is improved, the waste of resources is reduced, and at the same time, the cleanliness of the recycled water is ensured to avoid polluting the equipment. It includes:

[0031] A water storage bucket 1. The top opening of the water storage bucket 1 is connected to the water source through a water inlet pipe 2, and the bottom is connected to the equipment 4 through a water outlet pipe 3 to cool it. A first water pump 9 is fixed on the pipeline of the water outlet pipe 3 to pump the water in the water storage bucket 1.

[0032] A sedimentation tank 6. The water inlet of the sedimentation tank 6 is connected to the water outlet of the equipment 4 through a connecting pipe 5.

[0033] A recovery pipe 7. One end of the recovery pipe 7 is fixedly connected to the water outlet of the sedimentation tank 6, and the other end is connected to the top opening of the water storage bucket 1. A cooling plate 71 is fixed on the pipeline of the recovery pipe 7.

[0034] To further optimize the above - mentioned technical solution and facilitate the water in the sedimentation tank to enter the recovery pipe, a second water pump 8 is also included. The second water pump 8 is fixed on the pipeline of the recovery pipe 7 between the cooling plate 71 and the sedimentation tank 6 to pump the water in the sedimentation tank 6.

[0035] To further optimize the above - mentioned technical solution and ensure that the recycled water does not contain impurities, a filter 72 is detachably connected to the pipeline of the recovery pipe 7 close to the water storage bucket 1.

[0036] In this embodiment, the filter is a Y-type filter, which is convenient for disassembly. The filter uses a reverse osmosis membrane to filter out the tiny debris mixed in the recycled water in the recycling pipe, ensuring that the water entering the water storage bucket is clean and free of impurities, and preventing the recycled water from polluting the equipment.

[0037] In this embodiment, the sedimentation tank uses a three-stage sedimentation method to sediment and filter the cooled water. The sedimentation tank 6 is sequentially divided into a first sedimentation chamber, a second sedimentation chamber, and a third sedimentation chamber along its length direction by a first partition 61 and a second partition 62. An inlet is provided at the top of the side wall of the sedimentation tank 6 corresponding to the first sedimentation chamber, and an outlet is provided at the bottom of the side wall of the sedimentation tank 6 corresponding to the third sedimentation chamber.

[0038] To further optimize the above technical solution, a first water overflow trough 64 is provided at the top of the first partition 61, and a second water overflow trough 65 is provided at the top of the second partition 62. The first water overflow trough 64 and the second water overflow trough 65 are located on the same horizontal plane and are arranged staggeredly.

[0039] The water after the equipment is cooled first enters the first sedimentation chamber through a connecting pipe. After the first sedimentation is completed in the first sedimentation chamber, it flows into the second sedimentation chamber through the first water overflow trough. After secondary filtration in the second sedimentation chamber, it flows into the third sedimentation chamber through the second water overflow trough. After the third sedimentation and filtration in the third sedimentation chamber, it is pumped through the outlet into the recycling pipe for recycling.

[0040] The first water overflow trough and the second water overflow trough are arranged staggeredly, making the flow of the water entering the sedimentation tank in an S shape, improving the sedimentation and filtration effect.

[0041] To further optimize the above technical solution, to prevent the slag accumulated on the bottom wall of the sedimentation tank from being pumped into the recycling pipe, the distance between the outlet and the bottom wall of the sedimentation tank 6 is not less than 15 mm. The sedimentation tank is cleaned regularly to remove the bottom residue, preventing the outlet from being blocked due to excessive accumulation of the residue, and at the same time avoiding pumping the residue into the recycling pipe.

[0042] To further optimize the above technical solution and improve the sedimentation and filtration effect of the sedimentation tank, a filter screen 63 is fixed between the second partition 62 and the side wall of the sedimentation tank 6 where the outlet is provided. The filter screen is arranged in the third sedimentation chamber to isolate the un-sedimented residue.

[0043] In some other specific embodiments, the filter screen 63 is a 100- or 120-mesh filter screen, and the mesh diameter is not greater than 1 mm.

[0044] To further optimize the above technical solution, a water replenishing valve 21 is provided on the pipeline of the water inlet pipe 2. During the water cooling process of the equipment, due to the effect of heat exchange, water evaporation will occur, resulting in the recycled water not meeting the requirements of the equipment for water cooling. Therefore, the water replenishing valve is used to supplement the water in the water storage bucket.

[0045] In order to further optimize the above technical solution and realize the automation of water replenishment, a high liquid level detection sensor 11 is fixed to the top outer wall of the water storage barrel 1, and a low liquid level detection sensor 12 is fixed to the bottom outer wall. The high liquid level detection sensor 11 and the low liquid level detection sensor 12 are both electrically connected to the water replenishment valve 21.

[0046] The high liquid level detection sensor detects the highest water level. When the signal of the high liquid level detection sensor is transmitted to the water supply valve, the water supply valve is closed;

[0047] The low liquid level detection sensor detects the lowest water level. When the signal of the low liquid level detection sensor is transmitted to the water replenishment valve, the water replenishment valve opens to replenish the water storage tank. Embodiment 2:

[0048] The utility model embodiment discloses a device for recycling equipment cooling water, which is different from the first embodiment in that the sedimentation tank is replaced by a water storage tank, and a double filter 10 is fixed at one end of the recovery pipe close to the water storage tank;

[0049] When the water after equipment cooling enters the water reservoir, the second water pump first filters the water in the water reservoir through a double filter when extracting the cooling water in the water reservoir for recycling and reuse. When entering the water tank, it is filtered twice through a filter with a reverse filter membrane to ensure the cleanliness of the recycled water when it enters the water tank, ensuring that the equipment will not be polluted during the equipment water cooling process. Embodiment 3:

[0050] The utility model embodiment discloses a device for recycling equipment cooling water, which is used for water cooling of multiple equipments; it also includes a water distribution pipe 31;

[0051] The bottom of the water storage barrel 1 is connected with a water outlet pipe 3, and a water pump 9 is fixed on the pipeline of the water outlet pipe 3; there are multiple water distribution pipes 31, one end of each of the multiple water distribution pipes 31 is fixedly connected to the outer wall of the end of the water outlet pipe 3 away from the water pump 9, and the other end is connected to the device 4 in a one-to-one correspondence;

[0052] When the first water pump is turned on, the water in the water storage tank is pumped into the water outlet pipe, and the water in the water outlet pipe will enter each water distribution pipe respectively, and each water distribution pipe will be used for water cooling for each device corresponding to it;

[0053] In order to further optimize the above technical solution and improve the control effect of equipment water cooling, a control valve is fixed on each water distribution pipe, and the water flow entering the equipment through the water distribution pipe is controlled by the control valve. At the same time, when the equipment does not need water cooling, the control valve on the corresponding water distribution pipe can be closed, and only the control valve on the equipment that needs to be cooled needs to be opened to prevent water waste.

[0054] In the present specification, the various embodiments are described in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts among the various embodiments can be referred to each other. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the description in the method section.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
