Description

Technical Field

[0001] This utility model relates to the technical field of circulating water systems, and in particular to a sludge removal and water return structure. Background Technology

[0002] In existing water treatment or circulating water systems, small particulate impurities in the water (such as silt, suspended solids, colloidal particles, etc.) are easily deposited at the bottom of equipment or pipes due to gravity during the circulation process.

[0003] Over time, these deposited small particles of impurities may gradually agglomerate into large particles (such as flocs, clumps, or scale) through mechanisms such as physical aggregation, adsorption, or chemical reactions. If these large particles of impurities are not effectively intercepted, they will enter subsequent treatment units or equipment with the circulating water flow, leading to pipe blockage, increased equipment wear, reduced treatment efficiency, or even system failure. Utility Model Content

[0004] In view of the above-mentioned problems existing in the current circulating water system, the aim is to provide a sludge removal and water return structure.

[0005] The specific technical solution is as follows: A sludge removal and water return structure includes: A cylindrical body, the bottom of which has a drain outlet; The return water pipe and the circulation pipe are connected to the side wall of the cylinder and communicate with the inside of the cylinder. A perforated mesh plate is disposed inside the cylinder and located below the outlet end of the return water pipe and the inlet end of the circulation pipe. It is used to intercept large particles of impurities formed by the aggregation of small particles that settle to the bottom of the cylinder.

[0006] Furthermore, as a preferred embodiment, the outlet end of the return water pipe is located above the inlet end of the circulation pipe.

[0007] Furthermore, as a preferred embodiment, the perforated mesh plate has a plurality of holes, each of which has a diameter of 2-5 mm.

[0008] Furthermore, as a preferred embodiment, the inlet end of the return water pipe has an inlet connector.

[0009] Furthermore, as a preferred embodiment, the outlet end of the circulation pipeline has a connecting flange.

[0010] Furthermore, as a preferred embodiment, the sidewall of the return water pipe and the bottom of the cylinder are both equipped with temperature measuring connectors.

[0011] Furthermore, as a preferred embodiment, the perforated mesh plate is welded into the cylinder body.

[0012] Furthermore, in a preferred embodiment, the cylinder includes: a cylinder body, the cylinder body having an opening at both the top and bottom, the top of the cylinder body having an upper cylinder cover and the bottom having a lower cylinder cover.

[0013] Furthermore, as a preferred embodiment, the upper cylinder cover and the lower cylinder cover are respectively connected to the cylinder body by threads.

[0014] Furthermore, as a preferred embodiment, the perforated mesh plate is welded to the inside of the cylinder.

[0015] The positive effects of the above technical solution compared with the existing technology are: This invention introduces water into the cylinder through a return water pipe. Small particulate impurities in the water will settle to the bottom of the cylinder under their own weight, and form large particulate impurities through mutual aggregation, adsorption, or chemical reactions. When the circulation pipe is opened, the large particulate impurities will be intercepted by the perforated mesh plate, preventing the large particulate impurities from being discharged through the circulation pipe and preventing them from entering subsequent treatment units or equipment with the circulating water flow, which could lead to pipe blockage, accelerated equipment wear, reduced treatment efficiency, or even system failure.

[0025] Even better, the pore body can have a structure in which the pore diameter decreases from top to bottom, and the minimum opening diameter of the pore body is 2-5mm, which can ensure that small particulate impurities can settle smoothly to the bottom of the cylinder 1.

[0026] Furthermore, as a preferred embodiment, the inlet end of the return water pipe 2 has an inlet connector 6.

[0027] Furthermore, as a preferred embodiment, the outlet end of the circulation pipe 3 has a connecting flange 7.

[0028] Furthermore, as a preferred embodiment, the side wall of the return water pipe 2 and the bottom of the cylinder are both equipped with temperature measuring connectors 8 for installing thermometers to detect water temperature.

[0029] Furthermore, as a preferred embodiment, the perforated mesh plate 4 is welded inside the cylinder 1.

[0030] Furthermore, in a preferred embodiment, the cylinder 1 includes: a cylinder body 11, which has an opening structure at both the top and bottom ends, with an upper cylinder cover 13 at the top and a lower cylinder cover 12 at the bottom.

[0031] Furthermore, as a preferred embodiment, the upper cylinder cover 13 and the lower cylinder cover 12 are respectively threaded to the cylinder body 11, which facilitates processing and the installation of the perforated mesh plate 4.

[0032] Furthermore, as a preferred embodiment, the perforated mesh plate 4 is welded to the inside of the cylinder body 11.
