Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments:

in the following embodiments, "left, right", "front, back" and "inner" are directions determined only for convenience of the descriptors, and do not limit the structure of the present invention.

As shown in fig. 1 to 5, a dirt separating and cleaning device for an online cleaning system of a heat exchanger comprises a heat exchanger 11 and a device body, wherein more than one porous sieve tube 4 is arranged in the device body, a water inlet dispersion cavity 1 is arranged at the front end of the device body, a connector 12 is arranged at the front end of the water inlet dispersion cavity 1, and the connector 12 is connected with a water outlet end of a heat exchange tube of the heat exchanger; the effect that is equipped with dispersion chamber 1 of intaking lies in: the rubber balls flowing out of the heat exchange tubes of the heat exchanger can randomly enter the porous sieve tubes 4, the rubber balls are the existing commonly used rubber balls similar to sponge rubber, have certain contractibility, and can be selected conventionally according to the diameters of the heat exchange tubes in terms of the types of the rubber balls. The rear end of the device body is provided with a water outlet gathering joint, a V-shaped funnel 9 is arranged below the porous sieve tube, and the V-shaped funnel 9 is distributed along the flowing direction of cooling water, so that the device is designed and aims to solve the problems that: since the water flow is introduced from the inlet dispersion chamber 1 and then discharged from the outlet convergence joint, the V-shaped funnel 9 having the V-shaped structure and the connection manner using the above-mentioned orientation can promote the deepest depth of the lower middle portion of the V-shaped funnel 9 in the water flow direction, so that the advantage of the design is that the dirt is gradually sunk down during the water flow, the dirt which has sunk to the lower portion of the V-shaped funnel 9 can be further prevented from being washed up by the cooling water flowing from the front side, and the dirt which sinks to the rear side of the V-shaped funnel 9 can be sunk to the deepest depth along the inclined surface of the V-shaped funnel 9.

Two ends of the porous sieve tube are respectively communicated with the dispersion cavity and the water outlet gathering joint, so that rubber balls can smoothly enter the porous sieve tube and flow out; the following specific structure is adopted in this embodiment: the right side of the dispersion cavity and the left side of the water outlet converging joint are respectively provided with a porous sieve tube jack; and two ends of the porous sieve tube are respectively inserted into the jacks of the porous sieve tube for sealing connection. The purpose of this design is: prevent that cooling water from directly dashing into V-arrangement funnel 9, especially the colloid is filled in back in the porous screen pipe 4, and adopt above-mentioned structure, the cooling water must pass through porous screen pipe 4 can flow in V-arrangement funnel 9 and cooling water follow must pass through in the V-arrangement funnel 9 porous screen pipe 4 just can flow out water and assemble the joint, so can the significantly reduced right the impact and the outflow of sediment dirt in the V-arrangement funnel 9 improve the stability of sinking of sediment dirt in the V-arrangement funnel 9. The lower extreme of V-arrangement funnel 9 is equipped with dirt and collects chamber 6, the lower extreme opening of dirt collection chamber 6 just adopts the helicitic texture to dismantle sealedly through lid 7. When the sewage is drained, the cover 7 only needs to be screwed out, then the sewage is drained, and after the sewage is drained, the cover 7 only needs to be screwed tightly.

Further, in some embodiments, the perforated screen pipes 4 are arranged horizontally side by side, and the V-shaped funnels 9 under each perforated screen pipe are separated from each other, as shown in fig. 1, and two adjacent V-shaped funnels 9 are separated by a partition plate 8, which is beneficial: the interference between each porous sieve tube 4 can be reduced, the mutual influence among a plurality of V-shaped funnels 9 can be reduced, and the stability of dirt deposition is improved.

Further, as shown in fig. 1, more than 2V-shaped funnels are arranged below each perforated screen pipe 4, and the more than 2V-shaped funnels are connected end to end, and the cross section thereof forms a W-shaped structure, as shown in fig. 1, a second V-shaped funnel 5 is connected to the rear side of the V-shaped funnel 9, and further the lateral cross section thereof forms a W-shaped structure. The purpose of this design is to increase the effect of settling and the effect of collecting the dirt by connecting a plurality of V-shaped funnels to each other in order to reduce the impact of the flowing cooling water on the deposited dirt when the length of the perforated screen 4 is long.

Further, the diameter of the porous sieve tube 4 is consistent with that of the heat exchange tube of the heat exchanger.

Further, as shown in fig. 3, a barrier net 10 is further arranged in the V-shaped funnel 9, and this barrier net 10 has the function of reducing the impact of the flowing cooling water on the deposited dirt at the lower part of the V-shaped funnel 9, so as to promote the dirt to be better deposited in the dirt collecting cavity 6. Furthermore, the porous sieve tube is formed by punching the tube body or is made of a stainless steel net.

The utility model discloses when using, through inciting somebody to action connector 12 is connected to the water end is gone out to the heat exchange tube of heat exchanger 11, then assembles the play water of this device and connects in inserting the circulation pipeline, after starting online cleaning system, the rubber ball can follow the coolant flow in the circulation pipeline, flows through during the heat exchange tube of heat exchanger 11, it is right the inner wall of the heat exchange tube of heat exchanger 11 carries out the dirt and strikes off, and the dirt is then carried the outflow by the rubber ball the heat exchange tube of heat exchanger 11, then pass through the utility model discloses an it gets into to advance water dispersion chamber 1 porous screen pipe 4 under the effect of the hole of porous screen pipe 4, strike off the dirt on the rubber ball face, then fall into from the hole of porous screen pipe 4 in the V-arrangement funnel 9, simultaneously, deposit in the dirt is collected the chamber 6, after accumulating a period, only need unscrew lid 7, then the blowdown, only need will after having arranged lid 7 lid cover tightly can. The operation is simple and convenient, the use effect is good, the dirt scraped from the inner wall of the heat exchange tube of the heat exchanger 11 can be effectively reduced and carried to each area of the circulating pipeline, the influence of the dirt on the whole circulating pipeline is reduced, and the failure rate of other areas of the whole circulating pipeline is reduced.

The principles and embodiments of the present invention have been explained herein using specific examples, which are presented only to assist in understanding the methods and their core concepts.
