Description

Technical Field

[0001] This utility model relates to the field of belt limiting technology for belt vacuum dewatering filters, specifically a belt guide roller for a belt vacuum dewatering filter. Background Technology

[0002] Belt vacuum dewatering filters are high-efficiency, continuous solid-liquid separation devices widely used for dewatering high-moisture materials such as sludge, slurry, and chemical waste. Their working principle is based on vacuum negative pressure adsorption combined with mechanical transmission via the filter belt. After the material is evenly distributed, it passes through the filter cloth in a vacuum zone, achieving liquid suction and solid retention, ultimately forming a filter cake with a moisture content of 15%-25%. The core structure includes a corrosion-resistant filter belt, a vacuum system, a drive unit, and an intelligent correction system. It boasts advantages such as large processing capacity, low energy consumption, and a high degree of automation, making it particularly suitable for municipal sludge, tailings thickening, and food fermentation applications.

[0003] The belt guide roller (also known as the alignment roller, guide roller, or limit roller) of a belt vacuum dewatering filter is an important component of the filter belt running system. It is mainly used to ensure that the filter belt remains in the center position during operation, preventing deviation or slippage, thereby ensuring dewatering efficiency and equipment stability. Existing belt guide rollers do not have bearings and rely on the gap between the cylinder and the shaft to rotate. Over time, they will get stuck and stop rotating, and the grinding noise is very loud. To address this, we propose a belt guide roller for a belt vacuum dewatering filter. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a belt vacuum dewatering filter with a belt baffle roller. By installing bearings on the upper and lower parts and installing a skeleton oil seal, the cylinder rotates smoothly and without noise, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a belt baffle roller for a belt vacuum dewatering filter, comprising a support and a cylinder;

[0006] Support: A shaft is provided between its upper and lower ends;

[0007] Cylinder: Bearings are fixedly connected to both the upper and lower ends inside the cylinder. The shaft is rotatably connected between two bearings. Oil seals are movably fitted at both the upper and lower ends of the shaft. The oil seals are located on the outside of the adjacent bearings. With the upper and lower bearings installed and the skeleton oil seals installed, the cylinder rotates smoothly and without noise.

[0008] Furthermore, a nut is threaded onto the upper end of the shaft, and the nut is located at the upper end of the bracket to fix the shaft.

[0009] Furthermore, pressure caps are placed inside both the upper and lower ends of the cylinder, and oil seals are located inside adjacent pressure caps to protect the oil seals.

[0010] Furthermore, retaining springs are attached to the inside of both the upper and lower ends of the cylinder, and the retaining springs are located on the outside of the adjacent pressure caps to fix the pressure caps.

[0011] Furthermore, the coaxiality of the shaft is ≤0.5mm, which facilitates its insertion into the cylinder.

[0012] Furthermore, the bearing mounting diameter accuracy is ≤0.01mm, which facilitates the fit between the shaft and the bearing.

[0013] Furthermore, the outer diameter of the gland is the same as the inner diameter of the upper and lower ends of the cylinder to prevent the gland from shifting.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The belt baffle roller of this belt vacuum dewatering filter has the following advantages:

[0015] The shaft and cylinder are connected by bearings, and the bearings are isolated by oil seals to prevent grease leakage. The gland is fixed by snap rings to prevent the oil seal from shaking or shifting. The friction force of the cylinder rotation is minimal, and the rotation is smooth and noiseless.
