DETAILED DESCRIPTION

[0017] The following is combined with Figures 1 to 2 The utility model is described in detail.

[0018] The utility model discloses an energy-saving chilled water descaling device, comprising a main pipe 1 for guiding chilled water, wherein the main pipe 1 is provided with a side flow pipe 2, the side flow pipe 2 is arranged below the main pipe 1, both ends of the side flow pipe 2 are connected to the main pipe 1 and the inside of the side flow pipe 2 is interconnected with the main pipe 1, the main pipe 1 is provided with a first filter device 3, one end of the first filter device 3 is provided with a first choke valve 31, and the other end of the first filter device 3 is provided with a second choke valve 32, the side flow pipe 2 is provided with a second filter device 4, the second filter device 4 is arranged directly below the first filter device 3, one end of the second filter device 4 is provided with a third choke valve 41, and the other end of the second filter device 4 is provided with a fourth choke valve 42, and a controller 33 is included, and the first choke valve 31, the second choke valve 32, the third choke valve 41, and the fourth choke valve 42 are all electrically connected to the controller 33. In the solution of the utility model, the first choke valve 31 and the second choke valve 32 are opened or closed synchronously, and the third choke valve 41 and the fourth choke valve 42 are opened or closed synchronously. The first choke valve 31 and the third choke valve 41 are opposite. When the first choke valve 31 is opened, the third choke valve 41 is closed. In this structure, when the first choke valve 31 is closed, the third choke valve 41 and the fourth choke valve 42 are opened, and the pipes at both ends of the second filter device 4 are closed, and the chilled water can only pass through the first filter device 3; when the first choke valve 31 is opened, the third choke valve 41 and the fourth choke valve 42 are closed, the pipes at both ends of the first filter device 3 are closed, and the pipes at both ends of the second filter device 4 are opened, so that the chilled water enters the side flow pipe 2 from the main pipe 1 and then returns to the main pipe 1, and the chilled water passes through the second filter device 4. The first filter device 3 and the second filter device 4 of the utility model can filter the chilled water alternately. Specifically, the first filter device 3 and the second filter device 4 are both provided with a detachable filter 5, and the filter 5 is provided with a filter screen 51 and a filter cup 52 that can filter impurities. The double filter 5 is used to alternately filter the chilled water, thereby improving the chilled water filtering efficiency. When the filter 5 is alternated, there is no need to shut down the cooling unit, which is convenient to use. The maintenance personnel can manually remove the filter 5 that has stopped filtering for cleaning, remove the impurity crystals of the filter screen 51 and the filter cup 52, and reduce the frequency of using pipeline cleaning resources such as solvents. The filtering ability is strong, and it is energy-saving and environmentally friendly.

[0019] The filter 5 is provided with an inner pipe 53 having the same diameter as the inner wall of the main pipe 1 and the side pipe 2, and the filter screen 51 is detachably provided in the middle of the inner pipe 53. The filter 5 is installed after the first filter device 3 or the second filter device 4, and the inner pipe 53 is connected to the main pipe 1 or the side pipe 2. After the chilled water passes through the inner pipe 53, impurities and crystals will be intercepted on the filter screen 51, thereby cleaning the chilled water. When cleaning the filter 5, the filter screen 51 is disassembled, and then rinsed or hot-cleaned to remove the crystals attached to the filter screen 51, which is convenient for cleaning.

[0020] The inner pipe 53 is also provided with a fixing frame 54 for placing the filter cup 52. The fixing frame 54 is fixedly connected to the inner pipe 53 to fix the filter cup 52. There is a certain distance between the filter cup 52 and the filter screen 51, and the chilled water can be double filtered, with strong filtering ability.

[0021] More specifically, the mouth of the filter cup 52 is provided with a funnel-shaped flared portion 521. The mouth of the filter cup 52 faces in the opposite direction of the flow direction of the chilled water, the filter screen 51 is located at the bottom of the filter cup 52, and the density of the filter screen 51 is greater than the density of the filter cup 52. The filter cup 52 performs the first filtration on the chilled water, intercepts and filters the larger impurity crystals, and the filter screen 51 performs a more detailed second filtration, which greatly enhances the filtering performance of the filter 5.

[0022] The filter 5 is provided with a handle 55 on its exterior. The maintenance personnel can take the filter 5 out of the first filter device 3 or the second filter device 4 through the handle 55, and can hold the filter 5 stably, which is convenient for use.

[0023] The filter 5 is provided with a rubber strip 56 that can abut against the first filter device 3 or the second filter device 4. After the filter 5 is installed, the rubber strip 56 abuts against the first filter device 3 or the second filter device 4, so that the first filter device 3 or the second filter device 4 is sealed to prevent the freezing water from leaking out.

[0024] The first filter device 3 is provided with a baffle 34 at the bottom. The baffle 34 is in an "eight" shape, and protruding limit plates are provided on both sides of the top edge of the baffle 34. In this solution, the controller 33 is provided between the first filter device 3 and the second filter device 4. When the filter 5 is taken out of the first filter device 3, the residual liquid will be guided by the baffle 34 after flowing out, so as to prevent the controller 33 from being flooded.

[0025] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
