Description

Technical Field

[0001] This utility model belongs to the technical field of belt thickeners for solid-liquid separation of solid-liquid suspended materials under normal pressure, and relates to a nozzle clamping filter belt cleaning device for belt thickeners. Background Technology

[0002] A belt thickener is a device used for separating solid-liquid mixtures. It mainly consists of a feed chamber, a conveying and filtering chamber, a discharge chamber, a material conveying mechanism, a material distribution rake, an online filter belt washing device, and a filter belt tensioning device. The material conveying mechanism comprises a drive motor, a driving roller, a driven roller, an intermediate roller, an annular filter belt, a bearing housing, and a sliding bearing housing. The working process of the belt thickener is as follows: the solid-liquid mixture with added coagulant is stirred in a mixing tank and enters the feed chamber of the belt thickener. The material overflows from the top of the feed chamber and onto the filter belt. The liquid in the mixture permeates to the bottom of the annular filter belt, while the solid material remains on the annular filter belt and moves with it to the other end. The filtrate falls to the bottom of the conveying and filtering chamber and is discharged at the outlet, while the solid material enters the discharge chamber and is subsequently discharged. During operation, the online filter belt washing device washes the annular filter belt to improve its permeability.

[0003] The filter belt online spray washing device (refer to patent CN202122634001.X) mainly consists of a multi-nozzle water pipe, a rotating wire brush, an inlet flange, and a handwheel angle valve. It is installed between the upper and lower filter belts, with the nozzles facing the lower filter belt. After pressurizing and supplying water to the multi-nozzle water pipe, clean water is sprayed from the nozzles. This sprayed water acts on the annular filter belt, cleaning it, improving its permeability, and enhancing the filtration effect.

[0004] The existing multi-nozzle water pipes of filter belt online spray washing devices have the following defects: the nozzles are installed in the nozzle sleeves, and the nozzle sleeves are welded into the water outlet of the multi-nozzle water pipe. Not only is it inconvenient to weld the nozzle sleeves into the water outlet of the multi-nozzle water pipe, but the installation and disassembly of the nozzles are also inconvenient, time-consuming and labor-intensive, and the production process is complex and the production cost is high. Utility Model Content

[0005] The purpose of this invention is to overcome the defects of the multi-nozzle water pipes in existing online filter belt cleaning devices, solve the corresponding technical problems, and provide a nozzle-clamped filter belt cleaning device for belt concentrators.

[0006] The technical solution adopted by this utility model to solve the existing technical problems is: a nozzle clamping filter belt cleaning device for a belt concentrator (hereinafter referred to as: nozzle clamping filter belt cleaning device), mainly composed of three parts: cleaning pipe fittings, nozzle fastening kit, and nozzle sealing assembly. Compared with the existing technology, its innovative overall structure has outstanding substantive features: the cleaning pipe fittings are evenly provided with a water discharge hole, eliminating the need for nozzle sleeve welding in the original online filter belt cleaning device, saving materials and manpower, and reducing costs; the nozzle sealing assembly consists of a nozzle and a sealing ring, with the nozzle embedded in the sealing ring. When installing the nozzle-clamping filter belt cleaning device, the circular hole of the nozzle sealing assembly should be aligned with the water outlet on the cleaning pipe fitting. The nozzle fastening kit consists of an upper clamp, a lower clamp, and clamping bolts. A circular hole is formed between the upper and lower clamps, the diameter of which is slightly smaller than the outer diameter of the cleaning pipe fitting. The nozzle sealing assembly is installed in the nozzle hole of the lower clamp. By tightening the fastening bolts on both sides of the nozzle fastening kit, the upper and lower clamps can grip the cleaning pipe fitting tightly. At the same time, the sealing ring of the nozzle sealing assembly will also fit tightly around the water outlet on the cleaning pipe fitting, ensuring good sealing between the nozzle sealing assembly and the pipe wall around the water outlet. The advantages are: only the water outlet needs to be drilled on the cleaning pipe fitting, eliminating the need to weld the nozzle sleeve of the original filter belt online spray cleaning device, saving production costs; the nozzle is clamped to the water outlet of the pipe body using the nozzle fastening kit, making disassembly and installation more convenient.

[0007] Furthermore, the cleaning pipe fitting consists of a pipe body, an inlet flange, and an angle valve flange. The inlet flange and the angle valve flange are welded to the ends of the pipe body, respectively. A drain hole is evenly provided on the pipe body. The inlet flange is connected to an external water supply pipe, and the angle valve flange is connected to a handwheel angle valve. The clean water entering the cleaning pipe fitting is sprayed out at the drain hole.

[0008] Furthermore, the nozzle fastening kit consists of an upper clamp, a lower clamp, and fastening bolts. Both the upper and lower clamps are made of polypropylene and are injection molded in one piece. They are arc-shaped and, when assembled together, form a circular hole in the middle. The diameter of this circular hole is slightly smaller than the outer diameter of the cleaning pipe. Both the upper and lower clamps have external ears at both ends, and the fastening bolts are installed in the mounting holes of the external ears. The nozzle fastening kit is installed on the cleaning pipe, and its installation position corresponds to the position of the water outlet on the cleaning pipe. By tightening the fastening bolts, it can hold the cleaning pipe tightly. The bottom of the lower clamp has a nozzle hole for installing the nozzle sealing assembly.

[0009] Furthermore, the nozzle sealing assembly consists of a nozzle and a sealing ring, and is installed in the nozzle hole on the nozzle fastening kit, with the nozzle's large opening facing downwards during installation. The nozzle is shaped like a round cap with a lip-shaped opening, so that the high-pressure water jet from the nozzle forms a conical flow. The sealing ring is made of polyurethane, with an inner diameter slightly larger than the inner diameter of the water outlet on the cleaning pipe, an outer diameter matching the inner diameter of the nozzle hole on the nozzle fastening kit, and a thickness slightly greater than the depth of the nozzle hole on the nozzle fastening kit. The sealing ring has a groove, and the outer edge of the nozzle is installed in the groove.

[0010] The beneficial effects of the nozzle clamping filter belt cleaning device for belt concentrator provided by this utility model are: (1) The water outlet hole is directly drilled out of the pipe body of the cleaning pipe fitting, and there is no need to weld the nozzle sleeve at the water outlet hole, which makes the manufacturing process simpler and saves production costs; (2) The nozzle sealing assembly is located in the nozzle fastening kit. The nozzle can be fixed by tightening the fastening bolts on the nozzle fastening kit. Not only is the installation more convenient, but the disassembly and maintenance are also more convenient, saving time and effort. Attached Figure Description
