Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a continuous pressure filter dewatering device for high-viscosity waste residue. Background Technology

[0002] In many fields such as industrial production and wastewater treatment, the treatment of high-viscosity waste residue is a crucial step. High-viscosity waste residue typically contains a large amount of water; direct discharge or further processing not only increases transportation and treatment costs but can also cause serious environmental pollution. Therefore, effective dehydration of high-viscosity waste residue to reduce its water content is a key step in improving resource utilization efficiency and reducing environmental pollution. Filter press dehydration technology, as a common solid-liquid separation method, has broad application prospects in the treatment of high-viscosity waste residue.

[0003] Existing high-viscosity waste residue filtration technologies have shortcomings in practical applications. Traditional filtration equipment has poor adaptability to high-viscosity waste residues. Due to the high viscosity and low fluidity of high-viscosity waste residues, they easily clog the filter media during the filtration process, leading to a significant decrease in filtration efficiency, or even preventing normal filtration operations. On the other hand, existing filtration technologies struggle to achieve a continuous and stable dewatering process. Utility Model Content

[0004] The purpose of this invention is to provide a continuous pressure filter dewatering device for high-viscosity waste residue, so as to solve the problem of poor filtration effect of existing high-viscosity waste residue mentioned in the background art.

[0007] A bottom support plate is installed directly above the water collection hopper, which contacts the top wall of the bottom filter conveyor belt. Servo reduction motors that drive the bottom filter conveyor belt and the top filter press conveyor belt are installed on the side baffle.

[0008] The bottom support plate includes a support mesh plate and a fixing ring seat disposed at the edge.

[0009] Preferably, two sets of brackets for fixing the bottom support plate are installed between the side baffles on both sides, so that the bottom support plate maintains a stable position during the operation of the device and will not be displaced due to the operation of the bottom filter conveyor belt or the pressure it is subjected to, thereby ensuring the effective support of the bottom support plate for the bottom filter conveyor belt and ensuring the stability and reliability of the entire filter press dewatering process.

[0010] Preferably, each set of brackets has a support column installed on its top surface to support the bottom tray. This can evenly distribute the pressure on the bottom filter conveyor belt and the bottom tray, preventing the bottom tray from deforming or being damaged due to excessive local stress. At the same time, the presence of the support column also makes the installation of the bottom tray more precise and stable, which helps to improve the efficiency and quality of filter press dewatering.

[0011] Preferably, a scraper is installed between the side baffles on both sides to scrape off the residue at the discharge end of the top filter press conveyor belt, ensuring the cleanliness of the top filter press conveyor belt, maintaining the continuous and stable operation of the device, and improving the working efficiency of filter press dewatering.

[0012] Preferably, the filter residue discharge hopper is in close contact with the discharge end of the bottom filter screen conveyor belt to scrape off the residue at the discharge end of the bottom filter screen conveyor belt, which also helps to improve the discharge efficiency of the filter residue and ensure the normal operation and dewatering effect of the device.

[0013] Preferably, the four corners of the fixing ring seat are provided with positioning holes that are adapted to the size of the support column and can be inserted and matched, so as to facilitate the installation and positioning of the bottom support plate.

[0014] Preferably, one of the side baffles is equipped with a drain pipe connected to the bottom of the water collecting hopper, which can promptly discharge the filter water collected in the water collecting hopper out of the device.

[0015] Compared with existing technologies, the advantages of this utility model are as follows: In this continuous pressure filtration and dewatering device for high-viscosity waste residue, the high-viscosity waste residue is squeezed between the two conveyor belts by the bottom filter screen conveyor belt and the top pressure filter conveyor belt to achieve pressure filtration and dewatering; the side baffle limits the position of the bottom filter screen conveyor belt and the top pressure filter conveyor belt during the conveying process to prevent deviation; the water collection hopper can effectively collect the water filtered out; the filter cake discharge hopper can smoothly discharge the dewatered filter cake from the device; the bottom support plate is located directly above the water collection hopper and in contact with the top wall of the bottom filter screen conveyor belt, and the support plate and fixed ring seat can stably support the bottom filter screen conveyor belt during the conveying process to ensure stable operation of the pressure filtration process; the servo reduction motor is installed on the side baffle to drive the bottom filter screen conveyor belt and the top pressure filter conveyor belt respectively, providing power for the operation of the conveyor belt and realizing speed control, thereby realizing continuous pressure filtration and dewatering of high-viscosity waste residue.

[0028] Continuous filter press dewatering device for high-viscosity waste residue, such as Figures 1-3As shown, the system includes a bottom filter conveyor belt 10 for conveying high-viscosity waste residue. A top filter press conveyor belt 20 is installed on the top surface of the bottom filter conveyor belt 10. Side baffles 50 are symmetrically arranged on both sides of the bottom filter conveyor belt 10. A water collection hopper 30 is installed inside the bottom filter conveyor belt 10, and a filter residue discharge hopper 40 is installed at the discharge end of the bottom filter conveyor belt 10. A bottom support plate 60 is installed directly above the water collection hopper 30, contacting the top wall of the bottom filter conveyor belt 10. Servo reduction motors 51 are installed on the side baffles 50 to drive the bottom filter conveyor belt 10 and the top filter press conveyor belt 20 respectively. The bottom support plate 60 includes a support mesh plate 61 and a fixed ring seat 62 set at the edge. Through the bottom filter conveyor belt 10 and the top filter press conveyor belt 20, the high-viscosity waste residue is conveyed between the two conveyors. The belts are squeezed together to achieve filter press dewatering; the side baffle 50 limits the position of the bottom filter conveyor belt 10 and the top filter press conveyor belt 20 during the conveying process to prevent deviation; the water collection hopper 30 allows the filtered water to be effectively collected; the filter cake discharge hopper 40 allows the dewatered filter cake to be smoothly discharged from the device; the bottom support plate 60 is located directly above the water collection hopper 30 and in contact with the top wall of the bottom filter conveyor belt 10, and the support plate 61 and the fixed ring seat 62 provide stable support for the bottom filter conveyor belt 10 during the conveying process, ensuring the stable operation of the filter press process; the servo reduction motor 51 is installed on the side baffle 50 to drive the bottom filter conveyor belt 10 and the top filter press conveyor belt 20 respectively, providing power for the operation of the conveyor belts and realizing speed control, thereby realizing continuous filter press dewatering of high viscosity waste residue.

[0029] Furthermore, two sets of brackets 52 for fixing the bottom support plate 60 are installed between the side baffles 50 on both sides. Each set of brackets 52 has a support column 54 for supporting the bottom support plate 60 installed on its top surface, so that the bottom support plate 60 has an installation base and provides a support position for fixing the bottom support plate 60. The support column 54 installed on the top surface of each set of brackets 52 can stably support the bottom support plate 60, ensuring the stability of the bottom support plate 60 during operation, thereby ensuring the normal operation of the bottom filter conveyor belt 10.

[0030] It is worth noting that scrapers 53 are installed between the side baffles 50 on both sides to scrape off the residue at the discharge end of the top filter press conveyor belt 20, so that the residue at the discharge end of the top filter press conveyor belt 20 can be scraped off in time, avoiding the accumulation of residue from affecting the normal operation of the top filter press conveyor belt 20, and ensuring the continuity and efficiency of the filter pressing process.

[0031] The filter residue discharge hopper 40 is in close contact with the discharge end of the bottom filter screen conveyor belt 10 to scrape off the residue at the discharge end of the bottom filter screen conveyor belt 10, prevent the residue from flowing back with the bottom filter screen conveyor belt 10, ensure that the filter residue can be discharged smoothly from the device, and improve the dewatering efficiency.

[0032] Specifically, the four corners of the fixed ring seat 62 are provided with positioning holes 63 that are adapted to the size of the support column 54 and can be inserted and matched, so that the bottom support plate 60 can be accurately installed on the support column 54, achieving quick positioning and stable installation, and ensuring the contact stability between the bottom support plate 60 and the bottom filter conveyor belt 10.

[0033] In addition, a drain pipe connected to the bottom of the water collection hopper 30 is installed on one of the side baffles 50, so that the filter water collected in the water collection hopper 30 can be discharged from the device in a timely manner, avoiding the water level in the water collection hopper 30 being too high and affecting the filter pressing effect, and ensuring the continuous and stable operation of the device.

[0034] The working principle of this continuous pressure filter dewatering device for high-viscosity waste residue is as follows:

[0035] First, start the servo reduction motor 51 installed on the side baffle 50 to drive the bottom filter screen conveyor belt 10 and the top filter press conveyor belt 20 to start running; transport the high viscosity waste residue to the starting end of the bottom filter screen conveyor belt 10, and the waste residue moves forward with the bottom filter screen conveyor belt 10.

[0036] During the movement, the top filter press conveyor belt 20 squeezes the waste residue, and the water in the waste residue is squeezed out, passes through the bottom filter screen conveyor belt 10, and falls into the water collection hopper 30; the bottom support plate 60 directly above the water collection hopper 30 provides support for the bottom filter screen conveyor belt 10 through the support screen plate 61 to ensure the filter pressing effect.

[0037] As the conveyor belt continues to operate, the scraper 53 scrapes off the residue at the discharge end of the top filter press conveyor belt 20; at the same time, the filter residue discharge hopper 40 comes into close contact with the discharge end of the bottom filter screen conveyor belt 10, scraping off the residue on it, so that the filter residue can be smoothly discharged from the device; the filter water collected by the water collection hopper 30 is discharged from the device through the drain pipe connected to the side baffle 50; throughout the process, the bracket 52 and the support column 54 stably support the bottom support plate 60, ensuring the stable operation of the device and realizing continuous filter pressing and dewatering of high viscosity waste residue.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
