Description

Technical Field

[0001] This utility model relates to the field of cooling pump technology, and in particular to a cooling pump with a filtration function. Background Technology

[0002] Cooling water pumps are suitable for conveying clean water or liquids with physical and chemical properties in high-pressure operating systems, such as water supply for high-rise buildings, boiler feedwater, HVAC refrigeration circulation, hot and cold water circulation pressurization in bathrooms, and equipment matching, as well as for conveying or pressurizing pipelines in fire protection systems. Hard alloy seals of different materials ensure no leakage when conveying different media. For example, cooling water pumps made of integral stainless steel are suitable for industries such as chemical, food, brewing, pharmaceutical, and textile.

[0003] During machine tool processing, to prevent debris from mixing into the cooling water and damaging the impeller of the cooling pump, a patent publication number CN215170828U provides a machine tool cooling pump with a filtration function. This pump includes a base plate, a pump body fixedly connected to the top of the base plate, a motor fixedly connected to the right side of the top of the base plate, and the left end of the motor shaft penetrating into the inner cavity of the pump body. A water outlet pipe connects to the top of the pump body, and a filter box connects to the left side of the pump body via a pipe. A water inlet pipe connects to the left side of the filter box, and connecting blocks are fixedly connected to the top of both sides of the filter box. A cover plate is provided on the top of the filter box, and bolts are threaded through both sides of the top of the cover plate. Through the cooperation of the base plate, pump body, motor, water outlet pipe, filter box, water inlet pipe, cover plate, bolts, filter plate, frame, electric telescopic rod, horizontal pipe, spring, connecting rod, brush plate, and brush bristles, this pump achieves the advantage of filtering cooling water.

[0004] Based on the above search and analysis of existing technologies, it has been found that the filter structures of existing cooling pumps, similar to those disclosed above, require the pump to be stopped for cleaning, which is cumbersome. Furthermore, it is difficult for operators to determine the extent of clogging in the filter structure, and untimely cleaning leads to insufficient water flow. Therefore, a cooling pump with a built-in filter is proposed to address these issues. Utility Model Content

[0005] The purpose of this application is to provide a cooling pump with a filtration function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a cooling pump with a filtration function, including a pump body and a motor with its output end extending through the inside of the pump body. One end of the pump body is connected to a first water inlet pipe, and the other end is connected to a water outlet pipe. A first filter is fixedly connected to the first water inlet pipe, and two first water valves are respectively located on both sides of the first filter on the first water inlet pipe.

[0007] It also includes a second water inlet pipe, the two ends of which are fixedly connected to the first water inlet pipe on the side of the two first water valves that are far apart from each other. A second filter is fixedly connected to the second water inlet pipe, and two second water valves are respectively located on both sides of the second filter on the second water inlet pipe.

[0008] Both the first and second water inlet pipes are equipped with indicator devices.

[0009] As a further supplement to this solution, the alerting device includes an expansion cylinder, a rotating wheel, a rotating shaft, and an alarm assembly;

[0010] Both ends of the expansion cylinder are integrated with connecting pipes. The rotating wheel is mounted inside the expansion cylinder via a rotating shaft. The end of the rotating shaft passes through the expansion cylinder and is connected to the alarm component.

[0011] As a further supplement to this solution, the alarm components include a protective cover, a striking block, a spring, and a resilient connector;

[0012] The protective cover is fixed to the outside of the expansion cylinder, the spring is fixed to the inner wall of the protective cover, and the striking block is connected to the end of the rotating shaft located inside the protective cover through an elastic connector. The striking block can contact the spring during the rotation of the rotating shaft.

[0013] As a further supplement to this solution, the resilient connector includes a sliding column, a sliding sleeve, and a tension spring;

[0014] The sliding column is vertically fixed to the side end of the rotating shaft, and the sliding sleeve is slidably sleeved on the outer side of the sliding column away from the rotating shaft. The sliding sleeve is connected to the sliding column through a tension spring, and the striking block is fixed on the sliding sleeve.

[0015] As a further supplement to this solution, the protective cover is densely covered with sound holes.

[0016] As a further supplement to this solution, two indicator devices are located on the side of the first filter and the second filter near the pump body, respectively.

[0017] In summary, the technical effects and advantages of this utility model are as follows:

[0018] 1. In this utility model, by setting a first water inlet pipe connected to the first filter and a second water inlet pipe connected to the second filter, and cooperating with the first water valve and the second water valve, only one water inlet pipe is kept open at the same time. After one water inlet pipe cooperates with the filter to supply cooling water for a period of time, the other water inlet pipe can be switched to be open. After that, the filter corresponding to the previously opened water inlet pipe can be cleaned and replaced without stopping the cooling pump.

[0019] 2. In this utility model, by setting up an indicator device, when the filter structure inside the filter becomes clogged, the water flow drives the sliding sleeve and the striking block to rotate at a slower speed through the rotating wheel. Correspondingly, the centrifugal force on the striking block and the sliding sleeve decreases, and the tension of the tension spring decreases until the trajectory of the striking block's rotation passes the spring. At this time, the striking block contacts the spring during its rotation, thus emitting a "click-click-click" indicator sound. In addition, the protective cover is densely covered with sound holes, which makes it convenient for staff to know the clogging status of the filter structure inside the filter in a timely manner, so as to clean or replace the filter in a timely manner.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Reference Figure 1-4 The cooling pump shown includes a pump body 1 and a motor 2 with its output end extending into the inside of the pump body 1. One end of the pump body 1 is connected to a first inlet pipe 3, and the other end is connected to an outlet pipe 4. A first filter 7 is fixedly connected to the first inlet pipe 3. Two first water valves 8 are respectively located on both sides of the first filter 7 on the first inlet pipe 3. The pump body 1 also includes a second inlet pipe 5. Both ends of the second inlet pipe 5 are fixedly connected to the first inlet pipe 3 on the side of the two first water valves 8 that are far away from each other. A second filter 9 is fixedly connected to the second inlet pipe 5. Two second water valves 10 are respectively located on both sides of the second filter 9 on the second inlet pipe 5.

[0028] By setting a first water inlet pipe 3 connected to the first filter 7 and a second water inlet pipe 5 connected to the second filter 9, and cooperating with the first water valve 8 and the second water valve 10, only one water inlet pipe is kept open at the same time. After one water inlet pipe cooperates with the filter to supply cooling water for a period of time, the other water inlet pipe can be switched to open. After that, the filter corresponding to the previously opened water inlet pipe can be cleaned or replaced without stopping the cooling pump.

[0029] To facilitate timely notification of staff regarding the blockage status of the filter structure inside the filter, both the first inlet pipe 3 and the second inlet pipe 5 are equipped with an indicator device 11. Specifically, the indicator device 11 includes an expansion cylinder 111, a rotating wheel 112, a rotating shaft 113, and an alarm component. Both ends of the expansion cylinder 111 are integrally connected with connecting pipes 6. The rotating wheel 112 is rotatably mounted inside the expansion cylinder 111 via the rotating shaft 113, and the end of the rotating shaft 113 penetrates through the expansion cylinder 111. The alarm component includes a protective cover 114. The striking block 118, the spring 119, and the elastic connector are included. The protective cover 114 is fixed to the outside of the expansion cylinder 111. The spring 119 is fixed to the inner wall of the protective cover 114. The elastic connector includes a sliding column 115, a sliding sleeve 116, and a tension spring 117. The sliding column 115 is vertically fixed to the side end of the rotating shaft 113. The sliding sleeve 116 is slidably sleeved on the outside of the end of the sliding column 115 away from the rotating shaft 113. The sliding sleeve 116 is connected to the sliding column 115 through the tension spring 117. The striking block 118 is fixed on the sliding sleeve 116.

[0030] When the filter is filtering water normally, the water flow rate in the inlet pipe is relatively fast. This water flow, through the rotating wheel 112, drives the sliding sleeve 116 and the striking block 118 to rotate at a relatively fast speed. At this time, the centrifugal force on the striking block 118 and the sliding sleeve 116 is relatively large, and the tension spring 117 is in a stretched state. Furthermore, in this state, the trajectory of the striking block 118 does not pass through the spring 119, meaning that the striking block 118 does not contact the spring 119 during its rotation. When the filter structure inside the filter becomes clogged, the water flow through the rotating wheel 112 drives the sliding sleeve 116 and the striking block 118 to rotate at a slower speed. As the blockage worsens, the rotation speed of the sliding sleeve 116 and the striking block 118 decreases. Consequently, the centrifugal force on the striking block 118 and the sliding sleeve 116 decreases, and the tension of the tension spring 117 decreases until the trajectory of the striking block 118 passes the spring 119. At this point, the striking block 118 contacts the spring 119 during its rotation, thus producing a "click-click-click" sound. The protective cover 114 is densely covered with sound holes 11401, which allows staff to promptly detect the blockage of the filter structure inside the filter and clean or replace the filter in a timely manner.

[0031] Among them, the two indicator devices 11 are located on the side of the first filter 7 and the second filter 9 near the pump body 1, respectively, to prevent the rotating wheel 112 from being interfered with by impurities in the water.

[0032] The indicator devices 11 on the two water inlet pipes are staggered and spaced apart to avoid the two indicator devices 11 being too close together, making it difficult for staff to identify which indicator device 11 is making the sound.

[0033] The working principle of this utility model is as follows: Only one water inlet pipe is kept open at the same time. After one water inlet pipe is used in conjunction with a filter to supply cooling water for a period of time, the other water inlet pipe can be switched to open. After that, the filter corresponding to the previously opened water inlet pipe can be cleaned or replaced without stopping the cooling pump.

[0034] When the filter is filtering water normally, the water flow speed in the inlet pipe is relatively fast. The water flow drives the sliding sleeve 116 and the striking block 118 to rotate at a relatively fast speed through the rotating wheel 112. At this time, the centrifugal force on the striking block 118 and the sliding sleeve 116 is relatively large, the tension spring 117 is in the tension state, and in this state, the trajectory of the striking block 118 does not pass through the spring piece 119, that is, the striking block 118 does not contact the spring piece 119 during the rotation process.

[0035] When the filter structure inside the filter becomes clogged, the water flow through the rotating wheel 112 slows down the rotation speed of the sliding sleeve 116 and the striking block 118. As the clogging becomes more severe, the rotation speed of the sliding sleeve 116 and the striking block 118 becomes slower. Correspondingly, the centrifugal force on the striking block 118 and the sliding sleeve 116 decreases, and the tension of the tension spring 117 decreases until the trajectory of the striking block 118 passes the spring 119. At this time, the striking block 118 contacts the spring 119 during its rotation, thus emitting a "click-click-click" warning sound. The protective cover 114 is densely covered with sound holes 11401, which makes it convenient for staff to know the clogging status of the filter structure inside the filter in a timely manner, so as to clean or replace the filter in a timely manner.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
