DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0024] like Figure 2-4 The figure shows a wastewater proportioner described in the present invention, which includes a hollow cylinder 1. A medium inlet 31 is processed at one end of the cylinder 1, and a medium outlet 32 ​​is processed at the other end. The fluid medium enters the interior of the cylinder 1 through the medium inlet 31 and comes out from the medium outlet 32. A first inner core 4 and a tube core 2 are installed in the cylinder 1. The first inner core 4 is arranged along the central axis of the cylinder 1, and includes two sealing bodies 41 arranged at a certain distance and a connecting portion 42 connected between the two sealing bodies 41. The sealing body 41 is a piston body structure, and its outer peripheral surface is sealed and connected with the inner wall of the cylinder 1. Specifically, the outer peripheral surface of the sealing body 41 is sealed and matched with the inner wall of the cylinder 1 through a set sealing ring 7. The above-mentioned sealing matching method is a conventional means in the prior art and will not be repeated. The interior of the sealing body 41 is processed with a through hole 411 along the central axis direction. The tube core 2 is installed between the two sealing bodies 41, the middle part of the tube core 2 is wound on the connecting part 42, the two ends of the tube core 2 are respectively inserted into the through holes 411 on the corresponding side, and the outer wall of the tube core 2 and the inner wall of the through hole 411 are sealed and connected by a filler. Through the above structural design, the tube core 2 is fixed to the first inner core 4 by winding and fixing with a filler. On the one hand, a sealed fit is formed between the tube core 2 and the first inner core 4, and on the other hand, the length of the tube core 2 can increase with the increase in the number of winding times.

[0025] The above-mentioned filler is preferably a waterproof glue, such as Figure 5 , 6 As shown, the specific structure of filling glue is that an annular cavity 412 for filling glue is processed on the inner wall of the through hole 411 around the tube core 2, and a glue injection port 413 connected to the annular cavity 412 is processed on the outer peripheral surface of the sealing body 41. Glue is injected into the annular cavity 412 through the glue injection port 413, and the size of the glue injection port 413 is determined according to the size of the injection head of the glue syringe.

[0026] like Figure 5 , 6 As shown, the connecting portion 42 is integrally formed with two sealing bodies 41, the connecting portion 42 is a sheet-like structure, the sealing bodies 41 are connected to both ends of the connecting portion 42, an annular groove 421 is processed on the connecting portion 42, and the middle part of the tube core 2 is wound and clamped in the annular groove 421. By winding the tube core 2 multiple times, the length of the tube core 2 can be increased. The annular groove 421 is connected end to end, and a boss is formed in the middle, and the tube core 2 is wound around the boss.

[0027] like Figure 2-4As shown, a second inner core 6 is installed on one side of the first inner core 4 in the cylinder 1, and a filter mesh 5 is sandwiched between the first inner core 4 and the second inner core 6. The outer peripheral surface of the second inner core 6 is sealed and connected with the inner wall of the cylinder 1, and the sealing method is the same as that of the first inner core 4. A guide channel 61 is machined inside the second inner core 6 along the central axis direction. Figure 7 As shown, the guide channel 61 is in the shape of a stepped hole, and the diameter of the stepped hole decreases in sequence from the medium inlet 31 to the medium outlet 32 ​​.

[0028] The specific structure of the cylinder 1 is that openings 11 are processed at both ends of the cylinder 1. A gland 3 is installed on the opening 11. The medium inlet 31 is processed on the gland 3 on one side, and the medium outlet 32 ​​is processed on the gland 3 on the other side. The specific fixing method of the first inner core 4 and the second inner core 6 in the cylinder 1 is that an annular protrusion 12 is processed on the inner wall of one end of the cylinder 1, one end of the first inner core 4 abuts on the annular protrusion 12, and the end of the second inner core 6 away from the first inner core 4 abuts on the gland 3 processed with the medium inlet 31, so that the overall structure is fixed. In order to increase the sealing performance of the overall structure, a sealing ring 7 can also be installed at each abutment.

[0029] During assembly, first insert one end of the tube core 2 into the through hole 411 of the sealing body 41 on one side, then after the tube core 2 is wound around the annular groove 421 for several turns, the other end of the tube core 2 is inserted into the through hole 411 of the sealing body 41 on the other side, and a small amount of glue is injected into the annular cavities 412 on both sides through the glue injection port 413, and the glue is filled between the tube core 2 and the through hole 411, so as to seal the gap between the through hole 411 and the tube core 2. Next, insert the assembled tube core 2 and the first inner core 4 as a whole into the cylinder 1 from the opening 11 on one side, and then assemble the filter mesh 5 and the second inner core 6 in turn, and finally assemble the glands 3 on both sides at both ends of the cylinder 1. The gland 3 on one side is pressed against the second inner core 6 to fix the first inner core 4 and the second inner core 6 as a whole in the cylinder 1. The specific connection method between the gland 3 and the cylinder 1 can be a threaded connection method or a welding method.

[0030] When in use, wastewater enters from the medium inlet 31 , passes through the guide channel 61 , the filter mesh 5 , the tube core 2 in sequence, and then exits from the medium outlet 32 ​​.

[0031] The wastewater proportioner in this embodiment is processed in sections, and is used in conjunction with sealants and a small amount of glue, which is simple to assemble, has low processing costs, and can effectively reduce the risk of water leakage. On the other hand, both the first inner core 4 and the second inner core 6 can be replaced, which is convenient for replacement and maintenance.

[0032] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
