Description

Technical Field

[0001] The utility model relates to the technical field of water ring vacuum pumps, in particular to a cold water tank for a water ring vacuum pump. Background Art

[0002] A water ring vacuum pump is a pump device that uses water as a working medium to generate vacuum. Its working principle is based on liquid sealing and centrifugal force. The water ring vacuum pump cold water tank, also often called a water ring vacuum pump cooler or water tank, is an important component of the water ring vacuum pump system. Its main function is to store and circulate cooling water to maintain the normal operation and efficiency of the water ring vacuum pump.

[0003] When designing the cold water tank, in order to prevent impurities from entering the pump body, a filter is installed inside the tank to intercept impurities that may be contained in the cooling water, such as sand, metal chips, fibers, etc., to prevent these impurities from entering the vacuum pump and causing wear or damage to the impeller, pump casing or other components.

[0004] However, the filter may become clogged during use, so it needs to be checked and cleaned regularly to ensure smooth cooling water flow and normal operation of the system. If the filter is severely clogged, it may cause a reduction in cooling water flow, affecting the cooling effect and working efficiency of the vacuum pump. In previous filter cleaning methods, brushes or cleaning cloths are often used to clean the filter, which often cannot effectively clean the filter.

[0005] In view of this, a water ring vacuum pump cooling water tank is proposed. Utility Model Content

[0026] 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. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-7 .

[0028] The utility model discloses a cold water tank for a water ring vacuum pump, comprising a base 1, a pump body 2 fixedly connected to the base 1, and a box body 3 arranged on one side of the pump body 2 and fixedly connected to the base 1. A water inlet pipe 21 for conveying water to the pump body 2 and a water outlet pipe 22 for returning the heated water in the pump body 2 to the box body 3 are connected between the pump body 2 and the box body 3. An exhaust pipe 23 for discharging non-condensable gas and steam is also fixedly connected between the pump body 2 and the box body 3. A filter screen 4 is detachably provided in the box body 3, a cleaning plate 6 is slidably provided in the box body 3, a plurality of plugs 61 for cleaning the mesh of which are matched with the caliber of the filter screen 4 are provided at the bottom of the cleaning plate 6, and a scraper 5 slidably connected to the box body 3 for further cleaning the filter screen 4 is provided at the bottom of the filter screen 4.

[0029] It should be noted that the size of the plug 61 can be slightly smaller than the mesh of the filter 4, but during installation, the filter 4 should be fixed and the cleaning plate 6 should be moved downward to ensure that the plug 61 moves to a position inside the mesh of the filter 4.

[0030] In addition, a backwash port 32 for introducing clean water backwashing filter 4 is provided on the side of the box body 3 away from the pump body 2, and a drain port 33 is provided on the bottom of the backwash port 32. When backwashing, it is necessary to ensure that the cleaning plate 6 is higher than the height of the backwash port.

[0031] Among them, both ends of the scraper 5 are fixedly connected with a first slider 52 with a T-shaped cross-section, and a first slide groove 53 that is adapted to the size of the first slider 52 is correspondingly opened on the inner wall surface of the box body 3. An electric telescopic rod 51 is fixedly connected to the side of the box body 3 close to the pump body 2. The protruding end of the electric telescopic rod 51 passes through the box body 3 and is fixedly connected to the scraper 5. The position where the electric telescopic rod 51 passes through the box body 3 needs to be equipped with anti-leakage measures such as adding a rubber ring.

[0032] Again, both ends of the cleaning plate 6 are fixedly connected with a second slider 62 with a T-shaped cross-section, and a second slide groove 63 that is adapted to the size of the second slider 62 is correspondingly opened on the inner wall surface of the box body 3. The second slide groove 63 is used to limit the cleaning plate 6 to ensure its smooth movement. That is to say, after the filter 4 is fixed, the up and down movement of the cleaning plate 6 will not affect the alignment of the plug 61 and the mesh of the filter 4.

[0033] Furthermore, the top of the box body 3 is detachably connected to the box cover 31, and a screw 7 is provided through the middle position of the box cover 31. The bottom of the screw 7 is connected to the top of the cleaning plate 6 through a bearing. The screw 7 is threaded with a screw sleeve 8, and the screw sleeve 8 is fixedly connected to the first gear 10. The first gear 10 is rotatably connected to the top of the box cover 31. The first gear 10 is used to drive the screw 7 to drive the cleaning plate 6 to move up and down when it rotates. Since the screw 7 and the screw sleeve 8 are threadedly connected, and the screw sleeve 8 is rotatably connected to the box cover 31, and because the screw 7 and the cleaning plate 6 are rotatably connected, the screw sleeve 8 will drive the screw 7 and the cleaning plate 6 to rise or fall when it rotates.

[0034] Specifically, the bottom of the screw sleeve 8 is fixedly connected to a swivel 9 with an L-shaped cross section, and the swivel 9 is rotatably connected to the top of the box cover 31. Figure 7 As shown, the swivel 9 is located at the bottom of the screw sleeve 8. In addition to being able to rotatably connect the screw sleeve 8 and the box cover 31, the swivel 9 can also limit the screw sleeve 8.

[0035] In addition, the bottom of the box cover 31 is fixedly connected to the motor 12, and the output end of the motor 12 is fixedly connected to the second gear 11, and the second gear 11 is meshed with the first gear 10. That is to say, when the motor 12 is started, the motor 12 can drive the screw 7 and the cleaning plate 6 to move up and down.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
