Description

Technical Field

[0001] This utility model belongs to the technical field of sludge discharge auxiliary equipment, and relates to a rail clamping device for a traveling scraper in sewage treatment. Background Technology

[0002] In wastewater treatment systems, rectangular sedimentation tanks use chemical dosing in the reaction zone to induce flocculation of suspended solids, organic matter, and ions in the water. These flocculations are then carried out by gravity, settling to the bottom of the tank and achieving solid-liquid separation. This reduces the suspended solids content and provides favorable influent conditions for subsequent treatment processes. After the sludge settles in the sedimentation zone, it is scraped by a sludge scraper to a sludge hopper for further treatment. The sludge scraper in rectangular sedimentation tanks is typically a traveling scraper, with motor-driven wheels on both sides of the tank wall reciprocating along tracks. When there is a large amount of settled sludge in the sedimentation tank or when the scraper is subjected to uneven force on both sides, the traveling scraper's wheels are prone to derailment or the upper rail deviating from its track. Utility Model Content

[0003] The purpose of this utility model is to address the problems existing in the prior art by providing a rail clamping device for a traveling scraper in sewage treatment. This device solves the problems in the prior art where the traveling scraper's wheels are prone to derailment and the upper rail deviates from the track due to excessive sludge settling in the sedimentation tank or uneven force on both sides of the scraper under external forces.

[0004] Therefore, the present invention adopts the following technical solution: A rail clamping device for a traveling scraper in sewage treatment includes a rail clamping base plate, which is L-shaped and has a partition in the middle. The rail clamping base plate includes a vertical part and a horizontal part. The bottom of the horizontal part of the rail clamp base plate is provided with a rail clamping roller, and the two are connected by a shaft pin. The shaft pin passes through the rail clamp base plate and the two are connected by a first nut. The inner side of the rail clamping roller is provided with a deep groove ball bearing, and the deep groove ball bearing contacts the bottom of the rail clamp base plate through a spacer ring.

[0005] The vertical part of the base plate of the rail clamp is provided with several bolts arranged in a row.

[0006] A first washer and a first spring washer are sequentially provided between the first nut and the horizontal part of the bottom plate of the rail clamp.

[0007] A second washer and a second spring washer are sequentially provided between the bolt and the vertical part of the rail clamp base plate.

[0008] The angle between the vertical and horizontal portions of the base plate of the rail clamp is 90 degrees.

[0009] The beneficial effects of this utility model are as follows: During use, this utility model allows the scraper to make contact with the light rail in advance and slide on the light rail to continuously adjust its position, thus restoring it to normal operation. This effectively solves the problem in the prior art where the traveling scraper's wheels are prone to derailment and the upper rail deviates from the track due to excessive sludge settling in the sedimentation tank or uneven force on both sides of the scraper under external force.

[0012] The technical solution of this utility model will be described below with reference to the accompanying drawings and implementation methods.

[0013] like Figure 1 and 2 As shown, a rail clamping device for a traveling scraper in sewage treatment includes a rail clamping base plate 1, which is L-shaped and has a partition 12 in the middle. The rail clamping base plate 1 includes a vertical part and a horizontal part. In this embodiment, the angle between the vertical part and the horizontal part of the rail clamping base plate 1 is 90 degrees, and it is made of two steel plates welded together.

[0014] The vertical part of the rail clamp base plate 1 is provided with 4 bolts 9, arranged in 2 rows and 2 columns. A second washer 10 and a second spring washer 11 are provided between the bolts 9 and the vertical part of the rail clamp base plate 1 in sequence. Specifically, the bolts 9 are M12*25, the distance between adjacent bolts 9 on the left and right is 122.9mm, and the distance between adjacent bolts 9 on the top and bottom is 90mm, which are used to fix the rail clamp base plate 1 to the outer cover of the traveling wheel.

[0015] The bottom of the horizontal part of the rail clamping base plate 1 is provided with two rail clamping rollers 8. The outer diameter of the rail clamping rollers 8 is 55mm and the inner diameter is 35mm. The rail clamping rollers 8 are connected to the bottom of the horizontal part of the rail clamping base plate 1 by axle pins 2. Specifically, the axle pins 2 are M16 screws with a length of 95mm and a distance of 75mm from the vertical part of the rail clamping base plate 1. The distance between the two axle pins 2 is 117.9mm.

[0016] The pin 2 passes through the base plate 1 of the rail clamp and the two are connected by the first nut 5; the first washer 3 and the first spring washer 4 are arranged in sequence between the first nut 5 and the base plate 1 of the rail clamp.

[0017] The inner side of the rail clamping roller 8 is provided with a deep groove ball bearing 7; specifically, the deep groove ball bearing 7 adopts existing finished deep groove ball bearings; the deep groove ball bearing 7 contacts the bottom of the rail clamp base plate 1 through the spacer ring 6; the deep groove ball bearing 7 is used for support, fixation and positioning, and at the same time plays a sealing role to prevent lubricating oil leakage, prevent external contaminants from entering the bearing, and ensure good lubrication and working environment of the bearing.

[0018] The assembly process of this utility model is as follows: First, install the deep groove ball bearing 7 inside the rail clamping roller 8. After installation, insert the shaft pin 2, and insert the spacer 6 through the upper end of the shaft pin 2 to connect with the base plate 1 of the rail clamp. Finally, connect the base plate 1 of the rail clamp to the outer cover of the original sludge scraper's traveling wheel.
