Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and specifically discloses a device for adding a filter screen to the water inlet of a cooling tower. Background Technology

[0002] Cooling towers are widely used in industrial production and other fields. Their function is to cool circulating water by reducing the temperature of hot water through heat exchange between water and air. During the operation of a cooling tower, the water collection port is a key component for collecting the cooled water.

[0003] However, the current problem is that external debris such as packing material, leaves, insects, and dust particles can easily enter the cooling tower with the air and accumulate at the water inlet, eventually flowing into the circulating water system. This debris can cause pipe blockage, affecting the efficiency of circulating water flow, increasing the load on the water pump, leading to increased energy consumption, and in severe cases, even damaging the pump and other equipment. Simultaneously, the accumulation of debris can also breed algae and other microorganisms, affecting the water quality of the circulating water and adversely impacting the stable operation and lifespan of the entire cooling system. Therefore, a device that adds a filter screen to the cooling tower's water inlet is needed to solve this problem. Utility Model Content

[0004] This utility model proposes a device for adding a filter screen to the water inlet of a cooling tower. Through a quick-release snap-fit ​​mechanism, it achieves efficient impurity filtration and convenient maintenance, effectively protecting the cooling system equipment and improving work efficiency.

[0005] This utility model is implemented as follows: a device for adding a filter screen to the water inlet of a cooling tower includes a first frame and a second frame disposed at the water inlet of the cooling tower. Both the first frame and the second frame are cuboid in structure and have a filter screen on their outer walls. The first frame and the second frame are detachably connected by two identical snap-fit ​​mechanisms. Each snap-fit ​​mechanism includes an insertion hole opened on the outer wall of the first frame and the second frame. A U-shaped insert is inserted into the inner wall of the insertion hole. Two pin holes are opened through the outer wall of the U-shaped insert. The outer walls of the first frame and the second frame are slidably connected with pins that match the pin holes. A spring is fixedly connected between the outer wall of the pin and the first frame or the second frame.

[0006] As a preferred embodiment of the device for adding a filter screen to the water inlet of a cooling tower according to the present invention, the outer wall of the second frame opposite to the first frame has two symmetrically distributed limiting grooves, and the outer wall of the first frame opposite to the second frame has two limiting blocks that match the limiting grooves fixedly connected.

[0007] As a preferred embodiment of the device for adding a filter screen to the water inlet of a cooling tower according to this utility model, the first frame, the second frame, and the filter screen are all made of high-strength and corrosion-resistant metal material.

[0008] As a preferred embodiment of the device for adding a filter screen to the water inlet of a cooling tower according to this utility model, the lower end of the U-shaped insert rod is rounded.

[0009] As a preferred embodiment of the device for adding a filter screen to the water inlet of a cooling tower according to this utility model, the spring is a stainless steel compression spring, which is always in a compressed state and provides a biasing force to the pin toward the U-shaped insert.

[0010] In a preferred embodiment of this utility model, the inner diameter of the insertion hole matches the diameter of the U-shaped insertion rod.

[0011] Preferably, the high-strength, corrosion-resistant metal material used in this invention for adding a filter screen to the cooling tower water inlet is one of stainless steel, aluminum alloy, or galvanized steel.

[0012] The beneficial effects of this utility model are:

[0013] 1.

[0014] 2. A quick-connect mechanism consisting of a U-shaped insert, pin, and spring connects the two frames, enabling tool-free and rapid assembly and disassembly of the filter unit. This allows personnel to easily remove the entire unit for thorough cleaning or maintenance, greatly improving the efficiency of daily maintenance work. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-5 A device for adding a filter screen to the water inlet of a cooling tower includes a first frame 1 and a second frame 2 disposed at the water inlet of the cooling tower. Both the first frame 1 and the second frame 2 are cuboid structures and have a filter screen on their outer walls. The first frame 1 and the second frame 2 are detachably connected by two identical snap-fit ​​mechanisms. The snap-fit ​​mechanism includes an insertion hole 4 opened on the outer wall of the first frame 1 and the second frame 2. A U-shaped insert rod 3 is inserted into the inner wall of the insertion hole 4. Two pin holes 6 are opened through the outer wall of the U-shaped insert rod 3. The outer walls of the first frame 1 and the second frame 2 are slidably connected with pins 5 that match the pin holes 6. A spring 7 is fixedly connected between the outer wall of the pin 5 and the first frame 1 or the second frame 2.

[0024] In this embodiment: the first frame 1 and the second frame 2 are attached to the cooling tower water inlet. The two pins 5 on the same side are pulled outward to dislodge the pins 5 from the insertion holes 4. The U-shaped rod 3 is inserted into the corresponding insertion holes 4 of the first frame 1 and the second frame 2. The pins 5 are released, and the pins 5 are locked into the corresponding pin holes 6 of the U-shaped rod 3 under the elastic force of the spring 7. The U-shaped rod 3 on the other side is installed in the same way to fix the first frame 1 and the second frame 2. The filter screen can efficiently intercept various debris, greatly reducing the possibility of debris entering the circulating water system, ensuring the smooth flow of circulating water pipes and equipment, reducing the occurrence rate of equipment failure, reducing the wear and blockage of water pumps, pipes and other equipment by debris, reducing equipment maintenance costs, and extending the service life of the entire cooling system. The splicing installation method is convenient and quick, making it easy for personnel to install, disassemble and clean the filter screen, thus improving work efficiency.

[0025] As a technical optimization of this utility model, the outer wall of the second frame 2 opposite to the first frame 1 is provided with two symmetrically distributed limiting grooves 8, and the outer wall of the first frame 1 opposite to the second frame 2 is fixedly connected with two limiting blocks that match the limiting grooves 8.

[0026] In this embodiment, the first frame 1 and the second frame 2 can be quickly positioned by the cooperation of the limiting block and the limiting groove 8, thereby improving installation efficiency.

[0027] As a technical optimization of this utility model, the first frame 1, the second frame 2, and the filter screen are all made of high-strength and corrosion-resistant metal material.

[0028] In this embodiment, by using high-strength, corrosion-resistant metal materials for the first frame 1, the second frame 2, and the filter screen, the service life of the filtration device can be improved.

[0029] As a technical optimization of this utility model, the lower end of the U-shaped plug 3 is rounded.

[0030] In this embodiment: by setting the lower end of the U-shaped plug 3 to a round head, it is easier for the U-shaped plug 3 to be inserted into the plug hole 4.

[0031] As a technical optimization of this utility model, the spring 7 is a stainless steel compression spring, which is always in a compressed state and provides the pin 5 with a biasing force toward the U-shaped plug 3.

[0032] In this embodiment: by setting the spring 7 as a stainless steel compression spring, the pin 5 is ensured to automatically and continuously lock the U-shaped plug 3, thereby achieving quick and reliable connection and preventing loosening of the device.

[0033] As a technical optimization of this utility model, the inner diameter of the socket 4 matches the rod diameter of the U-shaped plug 3.

[0034] In this embodiment: by matching the inner diameter of the socket 4 with the diameter of the U-shaped plug 3, the U-shaped plug 3 is accurately inserted into the socket 4, effectively limiting its wobbling and ensuring the stability and firmness of the connection structure.

[0035] As a technical optimization of this utility model, the high-strength and corrosion-resistant metal material is one of stainless steel, aluminum alloy or galvanized steel.

[0036] In this embodiment, by setting the high-strength and corrosion-resistant metal material as one of stainless steel, aluminum alloy or galvanized steel, a variety of material options are provided to meet the requirements of corrosion resistance and strength, so as to adapt to the needs of different budgets and working environments.

[0037] The working principle and usage process of this utility model are as follows: During installation, the first frame 1 and the second frame 2 are aligned with the cooling tower water inlet. The two pins 5 on the same side are pulled outward to disengage them from the insertion holes 4. The U-shaped rod 3 is then inserted into the corresponding insertion holes 4 of the first frame 1 and the second frame 2. The pins 5 are then released, and under the elastic force of the spring 7, they are engaged in the corresponding pin holes 6 of the U-shaped rod 3. The same method is used to install the U-shaped rod 3 on the other side, thus fixing the first frame 1 and the second frame 2. The filter screen can efficiently intercept various debris, greatly reducing the possibility of debris entering the circulating water system, ensuring the smooth flow of circulating water pipes and equipment, reducing the incidence of equipment failure, reducing wear and blockage of water pumps, pipes, and other equipment caused by debris, reducing equipment maintenance costs, and extending the service life of the entire cooling system. The splicing installation method is convenient and quick, facilitating the installation, disassembly, and cleaning of the filter screen by personnel, thus improving work efficiency.
