Description

Technical Field

[0001] The utility model relates to the field of cooling tower water circulation, in particular to a cooling tower circulating water filtering device. Background Art

[0002] Cooling tower circulating water refers to the water that is circulated in the cooling tower system. This water is usually used to reduce the temperature of facilities such as industrial equipment, air-conditioning systems or power plants. As the condensed water evaporates and moves upward, it will encounter a barrier net and begin to adhere and condense to form water droplets. The water droplets will begin to drip due to the force of gravity. The dripping water will accumulate after entering the filter device, and then the filter device will filter the water flow to achieve a circulating operation. However, when existing devices filter the water flow, it is difficult to quickly separate the impurities accumulated in the upper water flow, which results in residual impurities in the water flow after the circulation treatment.

[0003] Therefore, a cooling tower circulating water filtering device is now developed in response to the above problems. Utility Model Content

[0004] In order to overcome the disadvantage that the existing device is difficult to quickly separate the impurities accumulated in the upper water flow when filtering the water flow, resulting in residual impurities in the water flow after the circulation treatment, the utility model provides a cooling tower circulating water filtering device.

[0005] The technical solution of the utility model is: a cooling tower circulating water filter device, including support columns, there are three support columns in total, a water collecting tray for collecting cooling water is connected between the tops of the support columns, the upper part of the water collecting tray is connected to a guide groove ring, the right part of the guide groove ring is provided with a water diversion groove, the lower part of the water collecting tray is connected to a circulation pipe, a filter element is clamped in the circulation pipe, and a descaling mechanism for cleaning the generated scale is provided on the left side of the water collecting tray.

[0006] As an improvement on the above scheme, the descaling mechanism includes a dual-axis motor, the dual-axis motor is connected to the inside of the water collecting tray, a placement seat is connected to the left side of the water collecting tray, a placement tank is connected to the placement seat, an inflow pipe is connected between the lower side of the placement tank and the water collecting tray, a rotating auger is rotatably connected in the inflow pipe, the lower part of the rotating auger is through-connected to the inflow pipe, and a differential transmission assembly is connected between the rotating auger and the lower output shaft of the dual-axis motor.

[0007] As an improvement of the above solution, a scraping mechanism is further included, wherein the scraping mechanism includes a nested ring, the nested ring is connected to the upper output shaft of the dual-axis motor, and the nested ring is connected to a scraping blade.

[0008] As an improvement of the above solution, the thickness of the right portion of the guide groove ring is greater than the thickness of the left portion.

[0009] As an improvement of the above solution, the filter element and the circulation pipeline are a detachable connection structure.

[0010] As an improvement of the above solution, the outer side of the scraper blade is provided with an inclined surface adapted to the water collecting tray.

[0011] By adopting the above technical solution, the utility model has the following advantages:

[0012] 1. The utility model recycles and collects condensed water in the water collecting tray, then guides and discharges the impurity water in the upper layer through the guide groove ring, relies on the circulation pipe and the filter element to filter and discharge the water flow in the lower layer, realizes the separation treatment after the condensed water is collected, improves the effect of the condensed water recovery cycle, and starts the double-axis motor after the circulation treatment, so that the descaling agent can automatically and evenly enter the water collecting tray, softens the scale on the inner side wall of the water collecting tray, and facilitates the cleaning of the scale.

[0013] 2. In the utility model, as the lower output shaft of the dual-axis motor starts to rotate, the upper output shaft of the dual-axis motor will also rotate synchronously, thereby driving the nested ring to rotate, so that the scraper can scrape and clean the inner wall of the water collection tray, scrape off the softened scale, and improve the cleaning efficiency.

DETAILED DESCRIPTION

[0019] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments. Example 1

[0020] A cooling tower circulating water filtering device, such as Figure 1 and Figure 2 As shown, it includes support columns 1, there are three support columns 1, and a water collecting tray 2 for collecting cooling water is connected between the tops of the support columns 1. The upper part of the water collecting tray 2 is connected with a guide groove ring 3, and a water diversion groove is opened on the right part of the guide groove ring 3. The thickness of the right part of the guide groove ring 3 is greater than that of the left part. The lower part of the water collecting tray 2 is connected with a circulation pipe 4, and a filter element 5 is clamped in the circulation pipe 4. The filter element 5 and the circulation pipe 4 are a detachable connection structure. A descaling mechanism 6 for cleaning the generated scale is provided on the left side of the water collecting tray 2.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, the descaling mechanism 6 includes a dual-axis motor 61, and the dual-axis motor 61 is connected to the inside of the water collecting tray 2, and the output shaft of the dual-axis motor 61 is arranged to face up and down. A placement seat 63 is connected to the left side of the water collecting tray 2, and a placement tank 64 is connected to the placement seat 63. The placement tank 64 is used to place and store the descaling agent, and an inflow pipe 65 is connected between the lower side of the placement tank 64 and the water collecting tray 2, and a rotating auger 66 is rotatably connected in the inflow pipe 65, and the lower part of the rotating auger 66 is through-connected to the inflow pipe 65, and a differential transmission assembly 62 is connected between the rotating auger 66 and the lower output shaft of the dual-axis motor 61.

[0022] It should be noted that when the cooling tower is working, it will rely on condensed water to achieve condensation and cooling by heat conduction. As the condensed water evaporates and moves upward, it will encounter a barrier net and begin to adhere and condense to form water droplets. The water droplets will begin to drip due to the gravity, and the dripping water droplets will fall into the water collecting pan 2. In the water collecting pan 2, as more and more condensed water is in the water collecting pan 2, the water level will begin to rise. When the water level rises to the position of the guide groove ring 3, the upper water flow will move to the right through the guide groove ring 3, thereby passing through the guide groove ring 3. The drinking trough discharges the impure water flow on the upper layer, and the water flow on the lower layer will be discharged through the circulation pipe 4. During the discharge process, the water flow is filtered by the filter element 5 to complete the collection and circulation of condensed water. Finally, the dual-axis motor 61 is started, and the rotation of the lower output shaft of the dual-axis motor 61 will drive the differential transmission assembly 62 to operate, thereby rotating the spiral auger, and then the descaling agent in the placement tank 64 enters the water collecting tray 2 along the inflow pipe 65, and softens the scale accumulated on the inner wall of the water collecting tray 2, so as to facilitate the subsequent cleaning of the water collecting tray 2. Example 2

[0023] On the basis of Example 1, Figure 1 and Figure 3As shown, a scraping mechanism 7 is also included, and the scraping mechanism 7 includes a nested ring 71. The nested ring 71 is connected to the output shaft on the upper side of the dual-axis motor 61. The nested ring 71 is connected to a scraping blade 72 for scraping and cleaning the inner wall of the water collecting tray 2. The outer side of the scraping blade 72 has an inclined surface that is adapted to the water collecting tray 2.

[0024] It should be noted that as the lower output shaft of the dual-axis motor 61 starts to rotate, the upper output shaft of the dual-axis motor 61 will also rotate synchronously, thereby driving the nested ring 71 to rotate, so that the scraper blade 72 can scrape and clean the inner wall of the water collection tray 2, scrape off the softened scale, and improve the cleaning efficiency.
