Description

Technical Field

[0001] The utility model relates to the technical field of circulating water tanks, in particular to a dry-proof vacuum pump circulating water tank. Background Art

[0002] A water ring vacuum pump is a type of vacuum pump that generates vacuum by forming a liquid ring with water. One of its important components is the circulating water tank, which is mainly used to store recycled water to ensure that the pump has sufficient water supply during continuous operation. It also plays a role in cooling and filtering, maintaining the temperature and cleanliness of the working fluid, thereby improving the working efficiency and life of the pump.

[0003] A search revealed an existing patent (publication number: CN218991872U) that discloses an automatic circulating water tank for a water ring vacuum pump, relating to the technical field of circulating water tanks. The invention comprises a tank body, with a water inlet pipe extending into the tank body fixedly mounted on the upper sidewall edge of the tank body. The water inlet pipe, located within the tank body, is connected to a float valve at one end. A water distribution mechanism is fixedly mounted below the inlet pipe. An electromagnetic outlet valve is fixedly mounted near the lower edge of the tank body. A control mechanism is fixedly mounted on the top of the tank body. The control mechanism includes a temperature sensor and a temperature controller, and a cleaning mechanism is fixedly mounted to the side of the temperature sensor. This utility model, through the coordination of the control mechanism, float valve, and electromagnetic outlet valve, achieves automatic circulation of cooling water within the tank body. This solves the problem of frequent manual cooling water changes required for water ring vacuum pumps, improves production efficiency, reduces labor input, and allows for cleaning of dirt from the tank walls, preventing clogging of the pipes.

[0004] However, in the above solution, although automatic water replenishment can be achieved, once a fault occurs, such as the valve on the water inlet pipe is damaged, or the water supply is cut off, once the temperature inside the box is high, the water inside the box will be automatically discharged, and the cooling water cannot be added in time due to the fault. This will result in insufficient water inside the box for the circulation of the vacuum pump, which will cause the vacuum pump to run dry and burn out, resulting in damage to the equipment.

[0005] In view of this, the utility model proposes an anti-drying vacuum pump circulating water tank. Utility Model Content

[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0028] The preferred embodiment of the anti-drying vacuum pump circulating water tank provided by the present invention is as follows: Figures 1 to 6 As shown: an anti-dry vacuum pump circulating water tank, comprising a box body 5; a sewage pipe 4 fixedly connected to the lower end of the front face of the box body 5, and a controller 3 is fixedly connected to one side of the front face of the box body 5; a pump body return pipe 6 fixedly connected to the upper end of the other side of the front face of the box body 5, and a pump body water supply pipe 11 is fixedly connected to one side of the bottom end of the box body 5; a water supply pipe 2 fixedly connected to the upper end of the front face of the box body 5, and a drain pipe 10 is fixedly connected to one side of the bottom end of the box body 5. A connecting pipe 16 is fixedly connected to one side of the inner bottom wall of the water supply pipe 2, and the bottom end of the connecting pipe 16 is connected to one side of the top of the drain pipe 10. A sliding cylinder 18 is movably connected to the surface of the connecting pipe 16; a box cover 1 movably connected to the top of the box body 5, and an exhaust pipe 7 is fixedly connected to one side of the top of the box cover 1; a filter assembly 15 assembled at the upper end of the inner wall of the box body 5, and the filter assembly 15 is used to filter the water transported by the water supply pipe 2; a temperature sensor 8 and a liquid level sensor 9 fixedly connected to one side of the box body 5 respectively.

[0029] An adjustment component is provided on the surface of the connecting tube 16, which is used to change the overall height of the connecting tube 16 and the sliding cylinder 18, so as to facilitate adjustment according to the water volume required by different vacuum pumps. The adjustment component includes: positioning holes 24 arranged at equal intervals on the surface of the connecting tube 16; a positioning groove 21 arranged at the lower end of the sliding cylinder 18; a positioning block 20 slidably connected to the inside of the positioning groove 21, one end of the positioning block 20 extends to the outside of the positioning groove 21, and the other end of the positioning block 20 is fixedly connected to a pull rod 23 extending to the outside of the sliding cylinder 18; a fixed spring 22 wrapped around the surface of the pull rod 23, and the two ends of the fixed spring 22 are respectively fixedly connected to one end of the positioning block 20 and the inner wall of the positioning groove 21.

[0030] In this embodiment, after the sliding cylinder 18 is pulled to a suitable height, the elastic force of the positioning groove 21 is used to make the positioning block 20 slide and clamp into the suitable positioning hole 24, so as to realize the limited fixation of the sliding cylinder 18 and the surface of the connecting pipe 16 after sliding. Then, when a fault occurs later and the drainage is not completed in time, due to the protruding connecting pipe 16 and the sliding cylinder 18, a certain amount of water still remains at the lower end of the box body 5, thereby preventing the vacuum water pump from running dry and burning the machine.

[0031] In a further preferred embodiment of the present invention, a locking structure is formed between one end of the positioning block 20 and the interior of the positioning hole 24 , and the length of the positioning block 20 is smaller than the depth of the interior of the positioning groove 21 .

[0032] In this embodiment, the sliding cylinder 18 and the communicating tube 16 are fixed in position after sliding by utilizing the engagement between one end of the positioning block 20 and the interior of the positioning hole 24 .

[0033] In a further preferred embodiment of the present invention, a limiting groove 17 is provided on one side of the surface of the connecting pipe 16 , and a limiting strip 19 is fixedly connected to the inner wall of the sliding cylinder 18 and slidably cooperates with the inner part of the limiting groove 17 .

[0034] In this embodiment, the sliding of the limiting strip 19 and the interior of the limiting groove 17 is utilized to improve the stability of the sliding cylinder 18 in sliding up and down. Example

[0035] On the basis of Example 1, the preferred embodiment of the anti-drying vacuum pump circulating water tank provided by the present invention is as follows: Figures 1 to 6 As shown: the filter assembly 15 includes: a fixing seat 1502 symmetrically fixedly connected to the inner wall of the box body 5; a slide groove 1501 opened on the inner wall of the fixing seat 1502; a slider 1503 movably connected to the inside of the slide groove 1501; and a filter frame 1504 fixedly connected to one side of the two sliders 1503.

[0036] In this embodiment, the water transported by the water supply pipe 2 can be filtered through the filter frame 1504 to reduce the accumulation of impurities in the water inside the box body 5. At the same time, after the box cover 1 is opened, the filter frame 1504 can be disassembled and thoroughly cleaned.

[0037] In a further preferred embodiment of the present invention, a locking structure is formed between the slider 1503 and the interior of the slide groove 1501, and the slide groove 1501 and the slider 1503 are convex in shape.

[0038] In this embodiment, the engagement between the convex sliding block 1503 and the interior of the sliding groove 1501 is utilized to improve the firmness and stability of the filter frame 1504 and the fixing seat 1502 after being engaged and installed.

[0039] In a further preferred embodiment of the present invention, one side of the top of the filter frame 1504 is lower than the horizontal plane of the water supply pipe 2, and the other side of the top of the filter frame 1504 is fixedly connected to a handle.

[0040] In this embodiment, a filter frame 1504 of a suitable height is used to facilitate water to enter the filter frame 1504 for filtration.

[0041] In a further preferred embodiment of the present invention, slots 12 are provided on both sides of the top of the box body 5 , and blocks 14 that engage with the inside of the slots 12 are fixedly connected to both sides of the inner wall of the box cover 1 .

[0042] In this embodiment, the engagement between the block 14 and the inside of the slot 12 is utilized to improve the firmness of the engagement between the box cover 1 and the box body 5 .

[0043] In a further preferred embodiment of the present invention, a guide plate 13 is fixedly connected to the inner bottom wall of the box body 5, and the top end of the guide plate 13 is inclined at an angle of ten degrees to the horizontal direction.

[0044] In this embodiment, the inclined guide plate 13 is used to quickly discharge the cleaned sewage.

[0045] The working principle of this utility model is as follows: first, the corresponding pipes are connected in sequence, and then the water volume required by different vacuum pumps or the water volume required for different working conditions is adjusted. At this time, the positioning block 20 is driven to slide in the positioning groove 21 by pulling the pull rod 23 to compress the fixing spring 22 until it is completely disengaged from the positioning hole 24. Then, the sliding cylinder 18 is pulled to slide to a suitable height on the surface of the connecting pipe 16. Then, the pull rod 23 is released, and the elastic force of the positioning groove 21 is used to make the positioning block 20 slide to the inside of the suitable positioning hole 24, so that the sliding cylinder 18 and the surface of the connecting pipe 16 are fixed after sliding.

[0046] External cooling water is transported to the interior of the box body 5 through the water supply pipe 2, and is filtered by the filter frame 1504 at this time to reduce the accumulation of impurities in the water inside the box body 5. The water is then transported to the vacuum pump through the pump body water supply pipe 11, and the water circulated by the pump body is transported back through the pump body return pipe 6. When the liquid level sensor 9 detects that the liquid inside the box body 5 is too low, the solenoid valve on the water supply pipe 2 can be opened to achieve automatic water replenishment. When the temperature sensor 8 detects that the temperature is high, the valve on the drain pipe 10 is opened to drain the water, and the cooling water is transported through the water supply pipe 2 to achieve mixed reduction of the water temperature.

[0047] When a fault occurs later and the water cannot be drained in time after drainage, due to the protruding connecting pipe 16 and the sliding cylinder 18, there is still a certain amount of water at the lower end of the box body 5, which prevents the vacuum water pump from running dry and burning the machine. At the same time, the box cover 1 can be opened, and then the filter frame 1504 can be pulled to make the slider 1503 slide and separate from the inside of the slide groove 1501, so as to realize the disassembly of the filter frame 1504, and facilitate the thorough cleaning of the filter frame 1504 after disassembly. At the same time, when cleaning the inner wall of the box body 5 later, after opening the box cover 1 to clean the inner wall of the box body 5, the valve on the sewage pipe 4 is opened, and then the guide plate 13 is used to discharge the cleaned sewage to ensure the cleanliness of the inside of the box body 5.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
