Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to a spinning-type sludge-water separation device. Background Technology

[0002] Sludge-water separation is a crucial step in the entire sludge treatment process. Its purpose is to enrich solids, reduce sludge volume, and create conditions for final sludge disposal. Sludge dewatering machines are equipment used to dewater sludge. Due to the multiple advantages of rotary extrusion sludge dewatering machines, including energy saving, stable and noiseless operation, sealed structure, simple daily maintenance, small footprint, convenient installation, low flushing water volume, and fully automatic control system, they are widely used in the market. Rotary extrusion sludge dewatering machines can be used for wastewater treatment, as well as for solid-liquid separation in the food and pharmaceutical industries, and have broad applications and promising development prospects.

[0003] However, in actual operation, existing sludge dewatering equipment is prone to clogging of the discharge port by sludge, affecting the normal operation of the equipment. After the equipment is used, sludge is easily left in its working chamber, requiring manual secondary cleaning by the staff, which affects the working efficiency of the equipment. Moreover, the existing sludge dewatering equipment does not dewater the sludge thoroughly enough and has high energy consumption. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a spinning-type mud-water separation device.

[0005] The technical solution of this utility model is: a spinning mud-water separation device, including a tank, a feed pipe that runs through the inside of the tank, a spinning disc that is slidably engaged inside the tank and sleeved outside the feed pipe, and a hydraulic cylinder that is set at the top of the tank and provides power to the spinning disc;

[0006] The bottom of the feed pipe is closed, and several through slots are evenly distributed on the lower part of the outer side wall of the feed pipe. Each through slot is slidably engaged with a baffle, and each baffle is equipped with a pull rod that penetrates the top of the feed pipe.

[0007] A water collection tank is installed at the top of the spinning disc and is fitted outside the feed pipe. A telescopic drain pipe is installed on the water collection tank and runs through the top of the tank. A filter plate is installed at the connection between the spinning disc and the water collection tank.

[0008] Furthermore, the bottom of the tank is a conical structure, and a sludge discharge pipe is installed at the bottom of the tank; a support is installed at the lower end of the outer side wall of the tank, and an overflow pipe is installed at the upper end of the outer side wall;

[0009] The output end of the hydraulic cylinder is connected to a telescopic rod that penetrates the tank and is connected to the spinning disc.

[0010] Note: After the sludge enters the tank and is left to stand, it forms layers, and the upper layer of wastewater can be discharged through the overflow pipe, which helps to reduce the difficulty of subsequent sludge dewatering.

[0011] Furthermore, a scraper is provided at the bottom of the tank; a drive motor is connected to the top of the tank via a mounting bracket; and a rotating shaft is provided at the output end of the drive motor, which passes through the feed pipe and is connected to the scraper.

[0012] Explanation: By using a drive motor to rotate the rotating shaft and scraper simultaneously, the sludge inside the tank after being spun can be scraped, which can prevent the sludge from sticking to the bottom of the tank and affecting the sludge discharge efficiency.

[0013] Furthermore, a lifting plate connected to each tie rod is installed at the top of the feed pipe; an electric push rod connected to the lifting plate is installed at the top of the tank body.

[0014] Note: The lifting plate is raised by using an electric push rod. At this time, all the baffles open simultaneously under the action of the pull rod, which helps to improve the ease of operation of the equipment.

[0015] Furthermore, a swing disk sleeved on the outside of the feed pipe is rotatably engaged on the bottom surface of the spinning disc; a connecting guide post is provided on the outer wall of the swing disk; and a spiral groove is provided on the inner wall of the tank body to slide and engage with the connecting guide post.

[0016] Explanation: When the spinning disc moves downward inside the tank, the cooperation between the connecting guide column and the spiral groove causes the oscillating disc to rotate at the bottom of the spinning disc and agitate the sludge, thereby reducing the difficulty of sludge spinning dewatering.

[0017] Furthermore, a cleaning scraper that abuts against the filter plate is provided on the upper surface of the oscillating disc;

[0018] Explanation: During the rotation of the oscillating disc, the cleaning scraper rotates at the bottom of the filter plate, and the rotating cleaning scraper can clean the filter plate.

[0019] The working principle of this utility model is as follows:

[0020] Sludge is fed into the feed pipe, and an electric push rod pushes the lifting plate upward. At this time, all the baffles open simultaneously under the action of the pull rod, and the sludge enters the tank through the through groove on the feed pipe. Then, the through groove is sealed by the baffle. The hydraulic cylinder drives the telescopic rod to extend downward, and the spinning disc moves downward inside the tank under the action of the telescopic rod. At this time, the water in the sludge enters the water collection tank through the filter plate and is discharged through the telescopic drain pipe. The drive motor drives the rotating shaft and the scraper to rotate simultaneously, scraping the sludge inside the tank after spinning, so that the sludge is discharged through the sludge discharge pipe. When the spinning disc moves inside the tank, the cooperation between the connecting guide column and the spiral groove makes the swing disc rotate at the bottom of the spinning disc and agitate the sludge. During the rotation of the swing disc, the cleaning scraper rotates at the bottom of the filter plate to clean the filter plate.

[0021] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects:

[0022] First, the structure of this utility model is reasonably designed. During the process of the sludge being squeezed by the swirl plate, the sludge is continuously agitated by the rotating oscillating plate, so that the water in the sludge can quickly enter the water collection tank during the squeezing and agitation process, thereby improving the working efficiency of the equipment.

[0023] Secondly, this utility model utilizes a drive motor to drive the rotating shaft and scraper to rotate simultaneously, which can scrape the sludge after it has been spun inside the tank, preventing the sludge from sticking to the bottom of the tank and improving the reliability of the equipment.

[0024] Third, the swing disc of this utility model can not only agitate the sludge, but also drive the cleaning scraper to clean the filter plate; at the same time, the rotation of the swing disc does not require an additional power source, thereby reducing the energy consumption of the equipment.
