Description
Technical Field
[0001] This utility model relates to the field of evaporators, and more particularly to an anti-clogging evaporator flow distribution structure. Background Technology
[0002] Evaporators are widely used heat exchange equipment in industries such as refrigeration, chemical, and food processing. Among them, the distributor is one of the key components of the evaporator, and its function is to evenly distribute the liquid refrigerant or solution entering the evaporator into each evaporation pipe to ensure evaporation efficiency and service life.
[0003] However, traditional distributors in the prior art have the following problems: impurities in the fluid tend to accumulate inside the distributor, especially in the branch pipes, causing blockages; blockages can lead to uneven flow distribution, reduced evaporation efficiency, and even system failures. Therefore, there is an urgent need for a distributor structure that can effectively prevent blockages and is easy to maintain. To this end, an anti-blockage evaporator distributor structure is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an anti-clogging evaporator diversion structure, which aims to improve the problem in the prior art where impurities in the fluid easily accumulate inside the diversion device, especially in the diversion branch pipe, causing blockage.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-clogging evaporator diversion structure, comprising a diversion body, a sealing element installed at the lower part of the diversion body, multiple diversion branch pipes installed at the lower part of the diversion body, an inlet pipe fixedly connected to the top of the diversion body, multiple connecting pipes fixedly connected to the bottom of the diversion body, a conical diversion cavity opened in the middle of the diversion body, an installation sleeve fixedly connected to the top of the diversion branch pipe, a filter element movably connected inside the installation sleeve, a sealing ring fixedly connected to the top of the filter element, and the connecting pipe threadedly connected to the installation sleeve, with the connecting pipe abutting against the sealing ring.

[0007] The inner wall of the branch pipe is fixedly connected with a spiral guide rib.
[0008] As a further description of the above technical solution:
[0009] A fixing pipe is fixedly connected to the bottom of the main body of the splitter.
[0010] As a further description of the above technical solution:
[0011] The sealing element includes a connecting post, which is threadedly connected to a fixed pipe, and a torsion block is fixedly connected to the bottom of the connecting post.

[0015] A tapered rod is fixedly connected to the top of the connecting column.
[0016] This utility model has the following beneficial effects:
[0017] 1. In this utility model, by setting a main body of the distributor and setting a conical distribution cavity inside it, the gradual contraction characteristics of the conical structure are used to accelerate the fluid flow and reduce the deposition of impurities. At the same time, the cooperation between components such as filter plates makes it easier to filter impurities, thereby preventing the distributor from clogging and making it more practical.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figure 1 - Figure 2 One embodiment of this utility model provides an anti-clogging evaporator diversion structure, including a diversion body 1 for diverting evaporator coolant. A sealing element 2 is installed at the lower part of the diversion body 1 for cleaning impurities inside the diversion body 1. Multiple diversion branch pipes 3 are installed at the lower part of the diversion body 1 to facilitate diversion. An inlet pipe 11 is fixedly connected to the top of the diversion body 1 for inlet fluid. Multiple connecting pipes 12 are fixedly connected to the bottom of the diversion body 1 for connecting the diversion branch pipes 3. A conical diversion cavity 13 is opened in the middle of the diversion body 1, allowing the diversion structure to utilize its tapered characteristics to accelerate fluid flow and reduce impurity deposition. A fixed pipe 14 is fixedly connected to the bottom of the diversion body 1 for installing the sealing element 2.
[0027] like Figure 3 As shown, a mounting sleeve 31 is fixedly connected to the top of the branch pipe 3, which is used to connect the branch pipe 3 and the connecting pipe 12. A filter 32 is movably connected inside the mounting sleeve 31 to filter impurities. A sealing ring 33 is fixedly connected to the top of the filter 32 to seal it. It may be made of rubber. The connecting pipe 12 is threadedly connected to the mounting sleeve 31, and the connecting pipe 12 abuts against the sealing ring 33. A spiral guide rib 34 is fixedly connected to the inner wall of the branch pipe 3, which can improve the fluid flow rate, reduce impurity deposition, and further reduce the risk of blockage.
[0028] Please see Figure 4 The sealing element 2 includes a connecting post 21, which is used to connect various components. The connecting post 21 is threaded to the fixed tube 14. A torsion block 23 is fixedly connected to the bottom of the connecting post 21, which is used to facilitate the disassembly and assembly of the sealing element 2. A sealing gasket 24, which may be made of rubber, is fixedly connected to the top of the torsion block 23. The sealing gasket 24 is movably connected to the lower part of the fixed tube 14. A tapered rod 22 is fixedly connected to the top of the connecting post 21, which is used to facilitate flow guidance.
[0029] Working principle: During use, the refrigerant enters the conical distribution chamber 13 inside the main body 1 of the distributor through the liquid inlet pipe 11 at the top of the distributor body 1. It is then transported to multiple connecting pipes 12 through the distribution chamber. When the coolant enters the distribution branch pipe 3 through the connecting pipe 12, the filter 32 installed between the connecting pipe 12 and the distribution branch pipe 3 will filter the coolant to prevent impurities from clogging the distribution branch pipe 3. After the coolant enters the distribution branch pipe 3, it will be guided by the spiral guide rib 34 and transported to the evaporator.
[0030] When it is necessary to clean the impurities on the filter 32, simply rotate the mounting sleeve 31 to separate it from the connecting pipe 12, then remove the filter 32 from the mounting sleeve 31 and clean it. Install the cleaned filter 32 into the mounting sleeve 31 with the side with the sealing ring 33 facing upwards, and then tighten the mounting sleeve 31 and the connecting pipe 12. When it is necessary to clean the impurities inside the distributor body 1, simply rotate the torsion block 23 to drive the connecting column 21 and the conical rod 22 to rotate, thereby separating the connecting column 21 from the fixed pipe 14 to clean the impurities inside the distributor. Then insert the connecting column 21 together with the conical rod 22 into the distributor body 1 and connect the connecting column 21 to the fixed pipe 14.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
