Description

Technical Field

[0001] This utility model relates to the field of belt filter presses, and in particular to belt thickening filter presses for wastewater treatment. Background Technology

[0002] The dewatering process of belt filter presses can be divided into four important stages: pretreatment, gravity dewatering, wedge zone pre-compression dewatering, and pressing dewatering. These utilize a variety of new equipment, including programmable automatic chamber filter presses, diaphragm filter presses, deep sludge dewatering filter presses, integrated sewage and sludge treatment equipment, and online precision filtration systems, offering reasonably priced and reliable environmentally friendly filtration products.

[0003] In existing belt filter presses, the filter cake typically falls through the discharge plate during discharge. However, the dehydrated filter cake still retains some stickiness and adheres to the surface of the discharge plate. To ensure the normal operation of the belt filter press, the discharge plate usually needs to be cleaned. However, the existing discharge plate has a simple structure, so cleaning requires manual labor, which is inefficient and consumes a lot of manpower and resources. Therefore, we propose a belt thickening filter press for wastewater treatment to solve the above problems. Utility Model Content

An inclined plate 11 is fixedly connected to the back of the first moving plate 5 and the front of the second moving plate 9. A bearing 7 is fixedly embedded inside the second adjusting cylinder 6. A threaded rod 8 is fixedly connected to the inner ring of the bearing 7. The end of the first moving plate 5 away from the bearing 7 is fixedly connected to the output end of the motor 10. The back of the first moving plate 5 and the front of the second moving plate 9 are both fixedly connected to the scraper 12. The outer surface of the inclined plate 11 is fixedly connected to the scraper 13. The first adjusting cylinder 3, the limiting rod 4, the first moving plate 5, the second adjusting cylinder 6, the bearing 7, the threaded rod 8, the second moving plate 9 and the motor 10 can form a cleaning mechanism for the inclined plate 11, which increases the convenience of cleaning the inclined plate 11, improves the efficiency of the workers in cleaning the inclined plate 11, reduces the consumption of manpower and material resources, and utilizes the design of the scraper 13. The scraper 13 has a certain degree of flexibility, which can avoid damage to the filter belt when scraping off the filter cake on the surface of the filter belt, thereby extending the service life of the filter belt.

[0023] The interior of the first movable plate 5 is slidably connected to the outer surface of the limiting rod 4, the interior of the second movable plate 9 is threadedly connected to the outer surface of the threaded rod 8, the right side of the inclined plate 11 is fixedly connected to the interior of the filter press body 1, and an electrical control cabinet 14 is fixedly connected to the back of the filter press body 1.

The latching groove 17 makes it easy for personnel to open the electrical control cabinet 14. The warning sign 16 prevents unauthorized personnel from approaching the electrical control cabinet 14 to avoid malfunctions. The cooperation between the support legs 18 and the base support plate 19 increases the stability of the device when placed.

[0025] The working principle of this utility model is as follows:

[0026] When cleaning the filter cake adhering to the surface of the inclined plate 11, the motor 10 is started first. The motor 10 will drive the threaded rod 8 to rotate. At the same time, the second moving plate 9 will move inside the second adjusting cylinder 6 according to the rotation direction of the threaded rod 8, thereby driving the scraper 12 to move on the surface of the inclined plate 11. When the scraper 12 moves, it will drive the first moving plate 5 to slide on the outer surface of the limiting rod 4 and inside the first adjusting cylinder 3, so that the scraper 12 will scrape off the adhering filter cake when it moves on the surface of the inclined plate 11, thereby completing the cleaning operation of the inclined plate 11.
