Description

Technical Field

[0001] This utility model relates to the technical field of condensate recovery devices, and in particular to a condensate recovery device for cooling towers. Background Technology

[0002] Cooling tower condensate is the water recovered and utilized by cooling towers during industrial cooling processes. The main function of a cooling tower is to dissipate heat from the system into the air through evaporation, thereby lowering the temperature of the water flowing through the tower. During operation, water is pumped to the top of the cooling tower and then evenly distributed through packing or nozzles to form a water film, exchanging heat with the air. In this process, some water evaporates, carrying away heat and lowering the water temperature. Condensate refers to the water that has cooled down in the cooling tower; it can usually be recycled and reused in the cooling circulation system, reducing water consumption. During the cooling process, condensate may contain dissolved solids, therefore, water treatment is required before use.

[0003] However, most existing condensate recovery devices for cooling towers filter impurities in the condensate through filter screens during actual use. But after a long period of use, a lot of impurities will accumulate on the surface of the filter screen, which will affect the filtration effect of the condensate, thereby reducing the condensate recovery rate and the condensate treatment efficiency. Therefore, it is necessary to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a condensate recovery device for cooling towers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A condensate recovery device for cooling towers includes a conveying cylinder with an auger rotatably connected inside. The conveying cylinder has a rotating mechanism for the auger. A first connecting box is fixedly connected to the arc surface of the conveying cylinder, and a water inlet pipe is fixedly connected to the top of the first connecting box, which is located at the top of the conveying cylinder. A second connecting box is fixedly connected to the arc surface of the bottom of the conveying cylinder. An arc-shaped screen plate is fixedly connected between the conveying cylinder and the second connecting box. The auger is in contact with the surface of the arc-shaped screen plate. A filtration mechanism is provided inside the second connecting box. The arc-shaped screen plate filters larger particulate impurities in the condensate, and the condensate is further filtered by the filter plate, thus improving the condensate treatment effect and increasing the condensate recovery rate.

[0007] Preferably, the rotating mechanism includes a rotating shaft, which is sleeved inside the center of the auger. The two ends of the rotating shaft are respectively rotatably sleeved inside the two ends of the conveying cylinder. A motor is installed at one end of the top of the conveying cylinder, and the output end of the motor is fixedly connected to the top of the rotating shaft for rotating the auger. This allows the auger to be rotated, thus conveying the filtered particulate impurities on the surface of the arc-shaped screen plate and improving the filtration effect of the arc-shaped screen plate on condensate.

[0008] Furthermore, a waste outlet is provided on the arc surface of the second connecting box. The waste outlet is located at the bottom of the higher end of the conveying cylinder surface. A waste pipe is fixedly connected to the surface of the conveying cylinder and is located on the surface of the waste outlet. Two fixing rings are sleeved on the surface of the conveying cylinder, and the same support frame is fixedly connected to the surfaces of the two fixing rings. This is used to support the device through the two fixing rings and the support frame, making the device more stable in use.

[0009] Preferably, the filtration mechanism includes a filter plate, a guide plate is fixedly connected inside the second connecting box, the guide plate is disposed at the bottom of the arc-shaped screen plate, the guide plate is inclined, the filter plate is slidably connected inside the second connecting box, the filter plate is disposed at the bottom of the guide plate, the bottom of the guide plate is disposed at the higher end of the top of the filter plate, fixing strips are fixedly connected to opposite sides inside the second connecting box, the two filter plates are respectively disposed inside the two fixing strips, a connection port is opened at the higher end of the surface of the second connecting box, the filter plate is slidably connected inside the connection port, a connecting plate is fixedly connected to one end of the surface of the filter plate, the connecting plate is disposed on the surface of the second connecting box, used for placing and removing the filter plate, and the condensate can be filtered again through the filter plate.

[0010] Furthermore, a water outlet pipe is fixedly connected to the bottom of the second connecting box, and a connecting pipe is fixedly connected to the lower end of the surface of the second connecting box. The connecting pipe is disposed on the top surface of the filter plate, and a sealing cap is installed at one end of the connecting pipe for collecting impurities on the surface of the filter plate, so that the impurities on the surface of the filter plate can slide into the inside of the connecting pipe, and at the same time, the impurities inside the connecting pipe can be removed through the sealing cap.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. During use, the device can perform secondary filtration of the passing condensate through the arc-shaped sieve plate and filter plate, thereby improving the treatment effect of the condensate.

[0013] 2. During use, condensate is transported through pipes to the first connecting box and the conveying cylinder. Then, the condensate inside the conveying cylinder flows into the second connecting box under the action of the arc-shaped screen plate. At the same time, the arc-shaped screen plate filters out larger solid impurities in the condensate. It can also drive the motor to rotate the shaft and auger, which can transport larger particles on the surface of the arc-shaped screen plate upward. The filtered impurities will then be discharged through the waste port and waste pipe. At the same time, it also cleans the surface of the arc-shaped screen plate and prevents it from clogging during use.

[0014] 3. The condensate entering the second connecting box flows through the guide plate to the top of the filter plate, and is then filtered again by the filter plate. The condensate after passing through the filter plate will flow downwards and finally be output outwards through the outlet pipe. Connect one end of the outlet pipe to a water pipe to recycle the treated condensate. The impurities filtered through the filter plate will be flushed to the lower end of the filter plate by the impact of the condensate, and then remain inside the connecting pipe. The impurities inside the connecting pipe can be cleaned by opening the sealing cover. After long-term use, the filter plate can be removed for cleaning. Attached Figure Description
