Description

Technical Field

[0001] This invention belongs to the technical field of wastewater pressure filtration, and specifically relates to a gradient pressure adaptive adjustment pressure filtration device. Background Technology

[0002] A filter press is a mechanical device that uses mechanical force to apply pressure to a filter medium to achieve solid-liquid separation. Its core principle is to use positive pressure dewatering (slurry dewatering) to trap solid particles in the suspension by the filter cloth to form a filter cake, while the liquid passes through the filter cloth and is discharged. Some models are equipped with a rubber extrusion membrane, which further squeezes the filter cake for dewatering by using a compression medium (such as air or water), or uses compressed air for blow-drying to minimize the moisture content of the filter cake. It is widely used in industries such as chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramics, environmental protection, and wastewater treatment. With the development of modern technology, especially in the treatment of wastewater generated in industry and various production processes, the use of pressure devices has become increasingly frequent, and the structure and function of the upper part of the filter press are constantly being improved to make it more efficient and convenient to use.

[0003] However, existing wastewater pressure filtration treatment devices still have the following drawbacks during use: 1. When the existing pressure device applies high pressure, the filter plates are squeezed together, and the wastewater being filtered forms sludge plates. If there is a small amount of water on the top, it will generate a certain tension, causing the filter plates to stick together. Since there are a lot of filter plates at the top of the filter press, it takes a lot of effort and time for the staff to manually separate each sticking filter plate. This not only increases the workload of the staff, but also reduces the efficiency of the filter plates in treating wastewater. 2. Existing filter press devices cannot adjust the pressure according to the flow rate and storage volume of wastewater during the filter press treatment process. The pressure adjustment of some filter press devices can only be manually adjusted by the staff by observing the flow rate. This filter press method is very inconvenient and cannot be adapted to the optimal pressure intensity for wastewater that has nowhere to be treated and filtered, thereby reducing the effect of filter press treatment of wastewater. 3. During the process of pressurizing wastewater, the pressurizing structure is located on one side of the filter plate, which is convenient for applying pressure. However, this layout will affect the separation distance of the filter plate in the later stage, making it inconvenient for staff to treat the solid sludge accumulated on the filter plate later, thus reducing the convenience of using the equipment.

[0004] Therefore, it is necessary to invent a gradient pressure adaptive adjustment filter press to solve the above problems. Summary of the Invention

The two ends of each spring are fixedly connected to one side of the inner wall of each mounting groove and one side of each baffle.

Preferably, the drive assembly includes lead screws rotatably connected to the inner walls of two limiting slide grooves, and the outer walls of the two lead screws are respectively threaded to the inner walls of two screw holes. One end of each of the two lead screws passes through the outer wall of one end of the adjusting frame and is fixedly connected to a synchronous pulley.

[0007] Preferably, the outer walls of the two synchronous pulleys are meshed with a synchronous belt, a motor is installed at one end of one side of the support frame, and the other end of one of the lead screws passes through the other end of the adjusting frame and is fixedly connected to the output end of the motor, and the motor is electrically connected to the first pressure sensor.

[0008] Preferably, a water inlet pipe is inserted and connected to one end of the support frame, and support legs are fixedly installed at both ends of the bottom of the support frame.

[0009] Preferably, the adjustable adaptive gradient pressure assembly includes a fixed plate fixedly installed on one side of the inner wall of the support frame, a movable plate rotatably connected to one side of the fixed plate, an electric hydraulic cylinder installed on one side of the movable plate, a push plate fixedly provided at the output end of the electric hydraulic cylinder, and extrusion plates fixedly provided on the other side of the inner wall of the support frame and one side of the push plate. An air guide pipe is inserted through the top of one of the extrusion plates located on the side of the push plate, and a flexible hose is inserted through the inner wall of the air guide pipe.

[0010] Preferably, a second pressure sensor is installed on one side of the electric hydraulic cylinder, and the inner wall of the hose is in communication with the interior of the second pressure sensor, and the second pressure sensor is electrically connected to the electric hydraulic cylinder.

[0011] Preferably, a handle is fixedly provided on one side of the outer wall of the electric hydraulic cylinder, and rollers are rotatably connected to both sides of the outer wall of the push plate, with the two rollers fixedly connected to both sides of the top of the support frame.

[0012] Preferably, each of the filter press shells has a filter screen installed on its inner wall, and each filter screen has a drainage hole in the middle position. The drainage holes are interconnected, and the water inlet pipe is connected to the inner wall of each drainage hole. Each of the filter press shells has a drain faucet installed on both sides, and one end of each drain faucet is connected to the inner wall of each side of the filter press shell.

[0013] Preferably, a control panel is installed on one side of the support frame, and the motor, the first pressure sensor, the second pressure sensor, and the electric hydraulic cylinder are all electrically connected to an external power source through the control panel.

[0014] The technical effects and advantages of this invention are as follows: 1. This invention stores wastewater in a filter press shell and inlet pipe, then applies pressure with a pressure-applying component to filter the wastewater. After the pressure-applying component is removed, the drive component is activated, causing the slider to slide in the limiting groove at the upper end of the adjusting frame. When the slider reaches the nearest edge of the filter press shell, the arc-shaped barb on the top of the slider presses against the lugs on both sides of the filter press shell. Since the arc-shaped surface of the barb is being pressed against it, it will rotate in the mounting groove. The slider continues to slide until the arc-shaped barb loses pressure, and then returns to its original position under the action of the torsion spring. At this time, one side of the lug contacts the first pressure sensor on the side of the baffle, triggering the reverse drive motor to make the slider slide in the opposite direction. The arc-shaped barb is limited by the top of the slider and will not flip. Then, through the sliding of the slider and the limiting pressure of the arc-shaped barb, the filter press shell moves and separates from the adjacent filter press shell. Repeating the above steps can automatically separate all the filter presses, reducing the workload of the workers and improving the processing efficiency. 2. This invention adjusts the airflow based on the amount of wastewater entering the filter press. As the amount of wastewater accumulated in the filter press shell gradually increases, the amount of airflow exiting the filter press shell increases. The airflow flows continuously through the air guide pipe and hose, pressing against the second pressure sensor, increasing the pressure on its upper end. The second pressure sensor is electrically connected to the electric hydraulic cylinder. As the pressure on its upper end increases, it continuously sends command signals to adjust the pressure intensity of the electric hydraulic cylinder. This design allows for adaptive pressure adjustment based on the wastewater flow rate, eliminating the need for manual adjustment of the pressure intensity by operators. This ensures that wastewater of different flow rates can be filtered under optimal pressure conditions, improving the filtration effect of the equipment. 3. This invention uses a movable plate and a fixed plate for rotational connection. When the movable plate overlaps the fixed plate, the electric hydraulic cylinder can apply pressure normally. After the filtration is completed, the operator can rotate the electric hydraulic cylinder through the handle, which will cause the movable plate to rotate on the fixed plate. Rotating to the state shown in the attached diagram of the instruction manual will allow the outer shells of each filter plate to be separated more thoroughly, providing the operator with better processing space to clean the sludge inside and improving the convenience of equipment use.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides, for example Figure 1 - Figure 8 The gradient pressure adaptive adjustment filter press device shown includes a support frame 1 and multiple filter press plate shells 2. The support frame 1 is characterized by having an automatic filter press plate separation mechanism 3, a drive assembly 4, and an adjustable adaptive gradient pressure assembly 7 installed on the top of the support frame 1. Each filter press plate shell 2 is installed at one end of the top of the support frame 1. The automatic filter plate separation mechanism 3 includes adjusting frames 301 installed on both sides of the outer wall of the support frame 1. Each adjusting frame 301 has a limiting groove 302 at the middle of its top. Each filter plate outer shell 2 has a hanging ear 303 fixedly installed on both sides of its outer wall, with the bottom of each hanging ear 303 slidably connected to both sides of the top of the support frame 1. A slider 304 is slidably connected to the inner wall of each limiting groove 302. Each slider 304 has an installation groove 305 at its top. Each end of the inner wall of each installation groove 305 has a connecting hole 306 on both sides. Two arc-shaped barbs 307 are rotatably connected to the inner walls of the four connecting holes 306. Torsion springs 308 are fitted onto the outer walls of both ends of each arc-shaped barb 307, and the two ends of each torsion spring 308 are respectively connected to four… One side of the inner wall of the connecting hole 306 and both sides of the two arc-shaped barbs 307 are fixedly connected. One end of each of the two sliders 304 is provided with a buffer hole 309. The other end of the inner wall of each of the two mounting grooves 305 is slidably connected with a baffle 310. One side of each of the two baffles 310 is equipped with a first pressure sensor 311. A buffer shaft 312 is fixedly provided at the lower edge of one side of each of the two baffles 310. A spring 313 is sleeved on the outer wall of one end of each of the two buffer shafts 312. The two ends of the two springs 313 are respectively fixedly connected to one side of the inner wall of each of the two mounting grooves 305 and one side of each of the two baffles 310. The outer walls of the two buffer shafts 312 are respectively inserted into the inner walls of the two buffer holes 309. The lower end of the inner wall of each of the two sliders 304 is provided with a screw hole 314. In use, wastewater is stored in the filter press shell 2 and inlet pipe 5, and then pressurized by the pressure application component to filter the wastewater. After the pressure application component is removed, the drive component 4 is activated, which moves the slider 304 in the limiting groove 302 at the upper end of the adjusting frame 301. When the slider reaches the nearest edge of the filter press shell 2, the arc-shaped barb 307 on the top of the slider 304 will press against the lugs 303 on both sides of the filter press shell 2. Since it is the arc-shaped surface of the arc-shaped barb 307 that is pressed against it, it will be squeezed and rotated in the mounting groove 305. The specific state is as shown in the attached instruction manual. Figure 3 As shown, the slider 304 continues to slide until the arc-shaped hook 307 loses its pressure. Under the action of the torsion spring 308, it returns to its original position. At this time, one side of the hanging ear 303 contacts the first pressure sensor 311 on the side of the baffle 310, which triggers the reverse drive motor 404 to make the slider 304 slide in the opposite direction. At this time, the arc-shaped hook 307 is limited by the top of the slider 304 so that it will not flip. Then, through the sliding of the slider 304 and the limiting pressure of the arc-shaped hook 307, the filter press shell 2 is moved and separated from the adjacent filter press shell 2. By repeating the above steps, all the filter presses can be automatically separated, which makes it convenient for the staff to clean the sludge blocks. There is no need for the staff to manually separate the filter presses with tension adsorption, which reduces the workload of the staff and saves the processing time of the filter presses, thus improving the processing efficiency. Furthermore, the drive assembly 4 includes lead screws 401 rotatably connected to the inner walls of the two limiting slide grooves 302, and the outer walls of the two lead screws 401 are respectively threaded to the inner walls of the two screw holes 314. One end of each of the two lead screws 401 passes through the outer wall of one end of the adjusting frame 301 and is fixedly connected to a synchronous pulley 402.

[0021] The outer walls of the two synchronous pulleys 402 are meshed with a synchronous belt 403. A motor 404 is installed at one end of one side of the support frame 1, and the other end of one of the lead screws 401 passes through the other end of the adjusting frame 301 and is fixedly connected to the output end of the motor 404. The motor 404 is electrically connected to the first pressure sensor 311. When the slider 304 slides on the adjusting frame 301 to separate the filter plate shell 2, the motor 404 is started to rotate one of the lead screws 401. Then, under the meshing transmission of the synchronous pulleys 402 and the synchronous belt 403, the lead screws 401 at both ends rotate synchronously, thereby driving the sliders 304 at both ends to slide synchronously on the adjusting frame 301 to separate the filter plate. Furthermore, a water inlet pipe 5 is inserted and connected to one end of the support frame 1, and support legs 6 are fixedly installed at both ends of the bottom of the support frame 1. Furthermore, the adjustable adaptive gradient pressure assembly 7 includes a fixed plate 701 fixedly installed on one side of the inner wall of the support frame 1. A movable plate 702 is rotatably connected to one side of the fixed plate 701. An electric hydraulic cylinder 703 is installed on one side of the movable plate 702. A push plate 704 is fixedly installed at the output end of the electric hydraulic cylinder 703. A squeezing plate 705 is fixedly installed on the other side of the inner wall of the support frame 1 and on one side of the push plate 704. A guide pipe 706 is inserted through the top of the squeezing plate 705 located on one side of the push plate 704. A hose 707 is inserted through the inner wall of the guide pipe 706. The guide pipe 706 and the squeezing plate 705 located on one side of the push plate 704 are interconnected. This results in more sewage accumulating inside the filter press shell 2, and more airflow is discharged. The airflow enters the hose 707 through the guide pipe 706 and is finally pressurized in the second pressure sensor 708.

[0022] A second pressure sensor 708 is installed on one side of the electric hydraulic cylinder 703, and the inner wall of the hose 707 is connected to the interior of the second pressure sensor 708. The second pressure sensor 708 is electrically connected to the electric hydraulic cylinder 703. As the amount of wastewater discharged increases, the amount of wastewater accumulated in the filter press shell 2 increases, resulting in more airflow above the filter press shell 2. The airflow flows continuously through the air guide pipe 706 and the hose 707, pressing against the second pressure sensor 708 and increasing the pressure on its upper end. Since the second pressure sensor 708 is electrically connected to the electric hydraulic cylinder 703, the increased pressure on its upper end will continuously send command signals to adjust the pressure intensity of the electric hydraulic cylinder 703. This design allows for adaptive pressure adjustment based on the wastewater flow rate, eliminating the need for manual adjustment of the pressure intensity. This ensures that wastewater volumes of different gradients can be filtered under optimal pressure conditions, improving the filtration effect of the equipment.

[0023] Furthermore, a handle 8 is fixedly provided on one side of the outer wall of the electric hydraulic cylinder 703, and rollers 9 are rotatably connected to both sides of the outer wall of the push plate 704. The two rollers 9 are fixedly connected to the two sides of the top of the support frame 1. They are rotatably connected through the movable plate 702 and the fixed plate 701. When the movable plate 702 overlaps the fixed plate 701, the electric hydraulic cylinder 703 can apply pressure normally. After the filter pressing is completed, the operator can rotate the electric hydraulic cylinder 703 through the handle 8, thereby causing the movable plate 702 to rotate on the fixed plate 701. Figure 2 The state shown allows for more thorough separation of the outer shells 2 of each filter press plate, providing staff with better processing space to clean the sludge inside and improving the ease of use of the equipment. Furthermore, each filter press shell 2 has a filter screen 10 installed on its inner wall. Each filter screen 10 has a drainage hole 11 in the middle, and each drainage hole 11 is interconnected. The water inlet pipe 5 is connected to the inner wall of each drainage hole 11. Each filter press shell 2 has a drain faucet 12 installed on both sides, and one end of each drain faucet 12 is connected to the inner wall on both sides of each filter press shell 2. The filter screen 10 is set inside the filter press shell 2. The inside is hollow, and sewage accumulates in it and is drained through each drainage hole 11 to cover the inside of each filter press shell 2. During the filtration process, the filtered sewage can be discharged by opening the drain faucets 12 on both sides, so that it quickly forms sludge blocks.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
