Description

Technical Field

[0001] The utility model relates to the technical field of silent water chillers, in particular to a green and environmentally friendly water pump for silent water chillers. Background Art

[0002] A chiller is a cooling water device that can provide constant temperature, constant flow and constant pressure. The operation of the chiller system is through three interrelated systems: the refrigerant circulation system, the water circulation system and the electrical automatic control system. The silent chiller does not produce any noise during operation, achieving the effect of green environmental protection. A water pump is a machine for conveying or pressurizing liquids. A water pump has the properties of high efficiency, low energy consumption, energy saving and environmental protection. Therefore, water pumps are widely used, and silent chillers also use water pumps for auxiliary use. For this reason, we provide a green and environmentally friendly silent chiller water pump.

[0003] During the use of the water pump, since there are often impurities in the water source transported inside the water pipe, these impurities are transported by the water pump for a long time, and some impurities are easily accumulated in the gaps of the water pump, affecting the use of the water pump. Utility Model Content

[0007] A filter unit is arranged on the inner wall of the input end of the pump housing, and a dust removal unit is arranged on the outer surface of the filter unit.

[0008] A further improvement of the technical solution of the utility model is that the filter unit includes a water inlet on the input end of the pump body shell, a water outlet is fixedly installed on the top of the pump body shell, an annular frame is fixedly installed on the inner wall of the water inlet, and a filter screen is fixedly installed on the inner wall of the annular frame, and the filter screen can filter the liquid entering the pump body.

[0009] A further improvement of the technical solution of the utility model is that the dust removal unit includes a fixing ring fixedly installed in the middle position of the filter screen plate, a driving rod is arranged inside the fixing ring, and a rotating ring is detachably sleeved on the left end of the driving rod.

[0010] A further improvement of the technical solution of the utility model is that: dust scrapers are fixedly installed on the outer surfaces of the upper and lower ends of the rotating ring, and the dust scrapers rotate and fit on the outer surface of the filter screen. A dust storage cavity is opened inside the dust scraper, and the rotation of the dust scraper can prevent impurities from adhering to the outer surface of the filter screen.

[0011] A further improvement of the technical solution of the utility model is that a storage cavity is opened in front of the fixed ring, and extrusion springs are fixedly installed on the four sides of the interior of the storage cavity. An extrusion ring is fixedly installed on the other end of the extrusion spring. The elastic driving force of the return spring causes the extrusion ring to fit and squeeze on the rear side of the rotating ring, so that its position is fixed.

[0012] A further improvement of the technical solution of the utility model is that: a resistance block is fixedly installed on both sides of the left end of the driving rod, and a positioning rod is fixedly installed on the inner side of the resistance block. The positioning rod is engaged in the positioning hole at the front end of the rotating ring, so that the installation position of the rotating ring is positioned.

[0014] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0015] The utility model provides a green and environmentally friendly soundless water pump for a chiller. The water inlet is arranged to facilitate the introduction of liquid into the interior of the pump body. The filter screen is arranged to filter the liquid entering the interior to prevent impurities from entering the interior to cause blockage and damage to the pump body, thereby achieving the effect of extending the service life of the pump body.

[0016] The utility model provides a green and environmentally friendly soundless water pump for a chiller. A driving rod is arranged to rotate at a uniform speed under the drive of a motor of the water pump itself, thereby causing a dust scraper plate to rotate on the outer surface of a filter screen plate, and scraping off impurities attached to the outer surface, thereby promoting the water flow rate. At this time, the water flow on the outer side of the filter screen plate is in a rotating state, and impurities contained in the water enter the dust storage cavity inside the dust scraper plate. Liquid flows out from the mesh holes at the rear of the dust storage cavity, while impurities are retained in the dust storage cavity, thereby preventing the mesh holes of the filter screen plate from being blocked, thereby achieving the effect of rapid dust removal.

[0017] The utility model provides a green and environmentally friendly soundless water pump for a chiller. The rotating ring is pushed backward so that the extrusion ring at the rear end moves backward and fits inside a storage cavity. At this time, the extrusion spring is in a retracted state. When the rotating ring moves backward, the positioning rod is prompted to disengage from the positioning hole. The rotating ring is then rotated ninety degrees. At this time, the resistance block corresponds to the engaging groove, which makes it easy to drive the dust scraper plate to be taken outward by the rotating ring, so as to facilitate cleaning of impurities inside the dust storage cavity and improve the use efficiency.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0025] like Figure 1-5As shown, the utility model provides a green and environmentally friendly silent water pump for a chiller, including a water pump body 1, which is suitable for a silent water chiller. The water pump body 1 includes a pump shell 2, and brackets 3 are arranged on both sides of the bottom end of the pump shell 2. A filter unit is arranged on the inner wall of the input end of the pump shell 2, and a dust removal unit is arranged on the outer surface of the filter unit. The filter unit includes a water inlet 21 on the input end of the pump shell 2, a water outlet 22 is fixedly installed on the top of the pump shell 2, an annular frame 23 is fixedly installed on the inner wall of the water inlet 21, and a filter screen plate 24 is fixedly installed on the inner wall of the annular frame 23.

[0026] Furthermore, by starting the water pump, water flows into the interior of the pump body from the water inlet 21 and is transported to the required place through the pipeline connected to the water outlet 22. When the water flows inside the water inlet 21, it can be filtered by the filter screen 24. Example

[0027] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the dust removal unit includes a fixed ring 25 fixedly installed on the middle position of the filter screen plate 24, a driving rod 26 is arranged inside the fixed ring 25, a rotating ring 27 is detachably sleeved on the left end of the driving rod 26, and a dust scraper plate 28 is fixedly installed on the outer surface of the upper and lower ends of the rotating ring 27, the dust scraper plate 28 is rotatably fitted on the outer surface of the filter screen plate 24, and a dust storage chamber 29 is opened inside the dust scraper plate 28.

[0028] Furthermore, during the filtering process, the driving rod 26 is driven by the motor of the water pump itself to rotate at a uniform speed. The other end of the driving rod 26 drives the rotating ring 27 to cause the scraper plate 28 to rotate on the outer surface of the filter mesh plate 24, so as to scrape off the impurities attached to the outer surface and promote the water flow rate. At this time, the water flow outside the filter mesh plate 24 is in a rotating state, and the impurities contained in the water enter the dust storage chamber 29 inside the scraper plate 28. The liquid flows out from the mesh behind the dust storage chamber 29, while the impurities are retained in the dust storage chamber 29. Example

[0029] like Figure 1-5 As shown, on the basis of Examples 1-2, the utility model provides a technical solution: preferably, a storage chamber 251 is opened in front of the fixed ring 25, and extrusion springs 252 are fixedly installed on all four sides of the interior of the storage chamber 251, and an extrusion ring 253 is fixedly installed on the other end of the extrusion spring 252, and a resistance block 261 is fixedly installed on both sides of the left end of the driving rod 26, and a positioning rod 262 is fixedly installed on the inner side of the resistance block 261, and a snap-fit ​​groove 271 is opened in the middle position of the interior of the rotating ring 27, and positioning holes 272 are opened on both sides of the snap-fit ​​groove 271.

[0030] Furthermore, after use, the rotating ring 27 can be pushed backward so that the extrusion ring 253 at the rear end moves backward and fits inside the storage chamber 251. At this time, the extrusion spring 252 is in a retracted state. When the rotating ring 27 moves backward, it prompts the positioning rod 262 to disengage from the positioning hole 272. Then the rotating ring 27 is rotated ninety degrees. At this time, the resistance block 261 corresponds to the engaging groove 271, which makes it easy to take out the scraper plate 28 driven by the rotating ring 27, so as to facilitate cleaning of impurities inside the dust storage chamber 29 or direct replacement.

[0031] The following is a detailed description of the working principle of the water pump used in this green and environmentally friendly silent chiller.

[0032] like Figure 1-5 As shown, when in use, the water pump is started, and water flows into the interior of the pump body from the water inlet 21, and is transported to the required place through the pipe connected to the water outlet 22. When the water flows inside the water inlet 21, it can be filtered by the filter screen 24 to prevent impurities in the water. At the same time, the motor of the water pump drives the driving rod 26 to rotate at a uniform speed. The other end of the driving rod 26 drives the rotating ring 27 to cause the scraper plate 28 to rotate on the outer surface of the filter screen 24, and the impurities attached to the outer surface are scraped off to promote the water flow rate. At this time, the water outside the filter screen 24 is in a rotating state, and the impurities contained in the water are removed. The liquid enters the dust storage chamber 29 inside the scraper plate 28, and flows out from the mesh holes at the rear of the dust storage chamber 29, while the impurities are retained in the dust storage chamber 29. After use, the rotating ring 27 can be pushed backward so that the extrusion ring 253 at the rear end moves backward and fits inside the storage chamber 251. At this time, the extrusion spring 252 is in a retracted state. When the rotating ring 27 moves backward, the positioning rod 262 is disengaged from the positioning hole 272. Then the rotating ring 27 is rotated ninety degrees. At this time, the resistance block 261 corresponds to the engaging groove 271, so that the rotating ring 27 can be driven by the scraper plate 28 to be taken out, so as to clean the impurities inside the dust storage chamber 29 or replace it directly.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
