Description

Technical Field

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

[0002] Closed cooling towers are mainly composed of a main unit, a water tank, a circulating water pump and an electric control cabinet. They are widely used in induction heating and metal capacity equipment (such as central power supplies and electric furnaces), cooling of circulating water in various reactors and condensers in the chemical industry, cooling of large molds such as metal die-casting molds and injection molds, etc.

[0003] The main working principle of a closed cooling tower is that the spray water evaporates on the outer wall of the coil to cool the cooling water flowing through the tube, and at the same time, the fan is used to take away the generated water vapor in time. A small part of the spray water is evaporated, and the rest is collected by the chassis and recycled.

[0004] In the Chinese utility model patent application number 200820138383.9, a closed cooling tower is proposed. The problem in this patent is that in the production process, the purity of the cooling water in the coil is required to be relatively high, and the cooling water will have certain impurities during the continuous circulation and cooling process. If it is not cleaned for a long time, it will cause damage to other equipment during the circulation process. Utility Model Content

[0005] The main technical problem to be solved by the utility model is to provide a cooling tower with a cooling water filtering device, which realizes timely and effective filtering and impurity removal of cooling water in the cooling tower, and solves the problem that the purity of cooling water does not meet the production process requirements after long-term circulation.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A cooling tower with a cooling water filtering device comprises a cooling tower body, a circulating water outlet pipe and a circulating water inlet pipe are installed on the side wall of the cooling tower body, and the circulating water outlet pipe and the circulating water inlet pipe are connected to a filter;

[0008] The filter is provided with a filter chamber and a return water chamber which are arranged up and down. The circulating water outlet pipe is connected with the inside of the filter chamber. A plurality of vertically arranged filter elements are installed in the filter chamber. A plurality of water holes are provided at the bottom of the filter chamber. The positions and numbers of the water holes correspond to the positions and numbers of the filter elements one by one. The inner side of each filter element is connected with the return water chamber through the water holes, and the inside of the return water chamber is connected with the circulating water inlet pipe.

[0009] The following is a further optimization of the above technical solution by the utility model: the filter includes a tank body and a tank cover that are snapped together, the filter chamber and the return water chamber are both arranged in the tank body, a plurality of lower positioning grooves are provided at the bottom of the filter chamber, and a plurality of upper positioning grooves are provided on the inner wall of the tank cover, the upper positioning grooves and the lower positioning grooves are arranged one by one, and the two ends of the filter element are respectively inserted into the corresponding upper positioning grooves and the lower positioning grooves, the lower end of each filter element is pressed against the bottom wall of the lower positioning groove, and each upper positioning groove is pressed against the upper end of the filter element.

[0010] Further optimization: a filter water inlet pipe is installed on the side wall of the lower end of the filter chamber, the water inlet end of the filter water inlet pipe is connected with the circulating water outlet pipe through an inlet hose, a V-shaped plate is provided on the inner side of the water outlet end of the filter water inlet pipe, and the two ends of the V-shaped plate are fixed on the inner wall of the filter chamber.

[0011] Further optimization: a lower positioning block is fixed in each of the lower positioning grooves, each lower positioning block is inserted into the inner side of the lower end of the corresponding filter element, each water hole is penetrated in the lower positioning block, an upper positioning block is fixed in each upper positioning groove, each upper positioning block is coaxially arranged with the corresponding lower positioning block, and each upper positioning block is inserted into the inner side of the upper end of the filter element.

[0013] Further optimization: the upper end of the tank body is fixedly connected to the tank cover via a locking ring.

[0014] The utility model adopts the above technical scheme and has the following beneficial effects: the utility model is ingenious in conception and reasonable in structure. The cooling water filtering and processing device is connected with the cooling coil inside the cooling tower. A part of the cooling water in the cooling tower flows out and enters the filtering and processing device for filtering and removing impurities. After long-term operation, all impurities in the cooling water can be filtered out, thereby realizing timely and effective filtering and removing impurities for the cooling water in the cooling tower, so that the purity of the cooling water is always maintained within the range required by the production process, thereby avoiding damage to the production equipment due to the cooling water purity not meeting the standard.

[0015] At the same time, the structure in which the tank body and the tank cover are separately arranged and the compressed filter element fixing method makes the disassembly and assembly of the filter element very simple, and facilitates the cleaning and replacement of the filter element in the filter.

[0028] In this embodiment, the circulating water outlet pipe 11 and the circulating water inlet pipe 12 are both connected to the cooling coil (not shown in the figure) inside the cooling tower body 1.

[0033] Among them, the filter 2 includes a tank body 24 and a tank cover 25 that are snap-fitted together, the filter chamber 21 and the return water chamber 22 are both arranged in the tank body 24, a plurality of lower positioning grooves 212 are provided at the bottom of the filter chamber 21, and a plurality of upper positioning grooves 251 are provided on the inner wall of the tank cover 25, the upper positioning grooves 251 and the lower positioning grooves 212 are arranged one by one, and the two ends of the filter element 211 are respectively inserted into the corresponding upper positioning grooves 251 and the lower positioning grooves 212, the lower end of each filter element 211 is pressed against the bottom wall of the lower positioning groove 212, and each upper positioning groove 251 is pressed against the upper end of the filter element 211.

[0034] In this embodiment, the filter element 211 is clamped, positioned and fixed by using the upper positioning groove 251 and the lower positioning groove 212 that are arranged opposite to each other, without the need for other complex fixing structures.

[0035] During operation, the operator only needs to remove the tank cover 25 to take out and place the filter element 211 in the tank body 24, which is very simple and convenient.

[0036] like Figure 2 and Figure 5 As shown together, a filter water inlet pipe 213 is installed on the side wall of the lower end of the filter chamber 21, the water inlet end of the filter water inlet pipe 213 is connected to the circulating water outlet pipe 11 through the water inlet hose 26, and a V-shaped plate 214 is provided on the inner side of the water outlet end of the filter water inlet pipe 213, and the two ends of the V-shaped plate 214 are fixed on the inner wall of the filter chamber 21.

[0047] In summary, the cooling tower with a cooling water filtering device proposed in the utility model realizes timely and effective filtering and impurity removal of cooling water in the cooling tower, and solves the problem that the purity of cooling water does not meet the production process requirements after long-term circulation.
