DETAILED DESCRIPTION
[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0022] Please refer to Figures 1-4 The filter press equipment of the environmental protection engineering in the embodiment comprises a frame body 1, a supporting plate 2 is fixedly installed at the bottom right side of the frame body 1, a plurality of clamping plates 3 and filter plates 4 are horizontally slidably installed between the inner walls on the front and back sides of the frame body 1, a buffer assembly 6 is fixedly installed at the bottom of the frame body 1, and a conveying belt 7 is fixedly installed at the left side of the supporting plate 2 and at the bottom of the buffer assembly 6.
[0023] It should be noted that the filter press plays an important role in the environmental protection engineering industry, and is usually used to realize the separation of solid and liquid phases. The structure of the filter press mainly includes filter plates 4 for realizing solid-liquid separation, a frame for supporting the filter plates 4, etc. In the working process of the filter press, the filter plates 4 in the frame are first pressed tightly by a pressing device, and then the solid-liquid mixture is delivered into the filter plates 4 for pressurization to separate the solid and liquid, and the separated solid material is discharged from between the filter plates 4, thereby realizing the separation of solid and liquid phases.
[0024] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The filter press of the environmental protection engineering includes a frame body 1, a supporting plate 2, a clamping plate 3, a filter plate 4, a driving assembly 5, a buffer assembly 6 and a conveying belt 7, so that the filter press avoids the problem that the material directly falls on the conveying belt 7 of the conveying device, causing the conveying belt 7 to be subjected to impact force for a long time during use, which is easy to cause damage, improves the service life of the device, and also achieves good buffering effect for the material.
[0025] Specifically, the conveying belt 7 forms a closed loop around the transmission drum and the redirection drum, the carrier roller supports the load section and the return section, the tensioning device ensures appropriate tension, the motor provides power, the transmission drum is driven to rotate after speed regulation by the speed reducer, and the conveying belt is driven to circulate by the friction between the transmission drum and the conveying belt.
[0026] The driving assembly 5 is fixedly installed inside the frame body 1, and the driving assembly 5 includes a hydraulic rod 501 fixedly installed on the right inner wall of the frame body 1, and a push plate 502 fixedly installed on the driving end of the hydraulic rod 501.
[0027] Specifically, in the working process of the filter press, the solid-liquid mixture needs to be delivered into the filter plates 4 for pressurization to realize solid-liquid separation, which requires that the filter plates 4 must be tightly attached to prevent material leakage. The hydraulic rod 501 in the driving assembly 5 is fixedly installed on the right inner wall of the frame body 1, and its driving end is connected to the push plate 502. When the hydraulic rod 501 is started, the push plate 502 will move to the left under the push of the hydraulic rod 501, thereby pushing the clamping plate 3 and the filter plate 4 to slide horizontally between the inner walls of the frame body 1 on the front and back sides, so that they are pressed tightly with each other to form a sealed filtering space, providing necessary conditions for solid-liquid separation.
[0028] The buffer assembly 6 comprises an intercepting frame 601 fixedly installed at the bottom of the frame body 1, a flow guide plate 602 movably installed on the left inner wall of the intercepting frame 601, a U-shaped frame 603 fixedly installed on the left inner wall of the intercepting frame 601 and located at the bottom of the flow guide plate 602, an electric push rod 604 fixedly installed on the inner bottom wall of the U-shaped frame 603, a moving block 605 fixedly installed on the driving end of the electric push rod 604, an auxiliary spring 606 fixedly installed on the inner top wall of the U-shaped frame 603, a traction rod 607 movably installed on the surface of the moving block 605, a reset spring 608 fixedly installed on the right inner wall of the intercepting frame 601, and an inclined plate 609 movably installed on the right inner wall of the intercepting frame 601.
[0029] Specifically, when the filter press completes solid-liquid separation and the separated solid material is discharged from between the filter plates 4, the material first falls onto the flow guide plate 602. Since the flow guide plate 602 is movably installed on the left inner wall of the intercepting frame 601, the impact force of the material will cause the flow guide plate 602 to rotate or displace to a certain extent. The material slides from the flow guide plate 602 onto the inclined plate 609. The inclined plate 609 will rotate to a certain extent after being impacted by the material. The reset spring 608 will buffer the rotation of the inclined plate 609 and help the inclined plate 609 return to the initial position after the material passes, thereby preparing for the next material falling. Finally, the material that has been buffered and guided falls onto the conveyor belt 7 and is transported to the next process.
[0030] Specifically, the action of the flow guide plate 602 is transmitted to the moving block 605 through the traction rod 607. At this time, the electric push rod 604 can control the extension and retraction action according to the falling condition of the material, such as the amount of material, the falling speed, etc., through the pre-set program or sensor feedback. When the electric push rod 604 extends and retracts, it drives the moving block 605 to move within the U-shaped frame 603. The auxiliary spring 606 buffers and assists the reset of the movement of the moving block 605. The movement of the moving block 605 further affects the state of the flow guide plate 602 through the traction rod 607, thereby adjusting the inclination angle and position of the flow guide plate 602 to better receive and guide the material.
[0031] In summary, by setting the buffer assembly 6, the separated solid material is prevented from directly falling onto the conveyor belt 7 with a large impact force, thereby reducing the risk of damage to the conveyor belt 7 due to long-term impact, improving the service life of the conveyor belt 7 and even the entire filter press equipment, and reducing the equipment maintenance and replacement costs.
[0032] Moreover, by setting the driving assembly 5, the clamping plate 3 and the filter plate 4 are tightly attached to form a sealed filtering space, which provides the necessary conditions for solid-liquid separation and ensures efficient solid-liquid separation. At the same time, the buffer assembly 6 can adjust the state of the flow guide plate 602 according to the falling condition of the material, thereby buffering and guiding the material and ensuring stable transportation of the material to the next process, thereby improving the overall work efficiency and stability.
