Description

Technical Field

[0001] This utility model belongs to the field of filter press technology, specifically relating to a filter press used in environmental protection projects. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a material, causing the liquid to seep out. It is a commonly used solid-liquid separation device, widely used in chemical production, and still widely used in industries such as chemical, pharmaceutical, metallurgical, dye, food, brewing, and environmental protection. The filter plates are stable in performance, easy to operate, safe, and labor-saving. The metal press cylinder is made of seamless steel pipe and the plastic steel filter plate is precision cast, which is resistant to high temperature and high pressure, and durable. When using a filter press, a filter screen is fixed on the filter plate, so that the solid and liquid are separated through the filter screen, thereby achieving the effect of liquid permeation.

[0003] For example, in Chinese utility model patent CN219423810U, entitled "A Filter Press for Environmental Engineering," a base plate is included. A frame is fixedly connected to the top of the base plate near the center of both sides. A filter press is fixedly connected to both frames near the top. Several filter plates are sleeved on the power output shaft of the filter press. This prior art avoids the problem of impurities falling onto the base plate requiring secondary cleaning, reducing the workload of workers. It also allows for easy removal of the collection box from the protective box cavity, facilitating the removal of impurities stored in the collection box for unified processing, thus improving convenience. However, long-term use results in impurities remaining on the guide plate, affecting the impurity collection effect and the cleanliness of the device, leading to reduced subsequent work efficiency. Therefore, a filter press for environmental engineering is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a filter press with a simple structure and reasonable design for environmental protection engineering in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A filter press for environmental protection engineering includes a transmission pipe, a fixed plate 1 fixedly connected to the output end of the transmission pipe, two slide rods fixedly connected to the outer side of the fixed plate 1, a fixed plate 2 fixedly connected to the other end of the two slide rods, drainage components provided on both sides of the fixed plate 1, and a material guiding component provided at the bottom of the fixed plate 1.

[0007] As a further optimization of this utility model, the drainage assembly includes two collection containers that are simultaneously slidably disposed inside the inner sides of a first fixed plate and a second fixed plate. The inner side of the second fixed plate has an installation groove that is slidably disposed with the outer sides of both collection containers. The inner side of the first fixed plate has two limiting grooves. The outer sides of both collection containers are fixedly connected to limiting plates inserted into the limiting grooves. One bottom end of each collection container is fixedly connected to a drain pipe. The outer side of each collection container abuts against a baffle. The inner sides of the first fixed plate and the second fixed plate have fixing grooves that are slidably disposed with the inner sides of the two baffles.

[0008] As a further optimization of this utility model, the material guiding assembly includes two side plates that are simultaneously fixedly connected to the bottom of the first fixed plate and the second fixed plate. The inner sides of the two side plates are provided with sliding grooves, and the bottoms of the two side plates are fixedly connected with material guiding inclined plates.

[0009] As a further optimization of this utility model, a cylinder is fixedly connected to the bottom of the guide plate, a fixed frame is fixedly connected to the output end of the cylinder, and sliding shafts that are slidably disposed inside the slide groove are fixedly connected to both ends of the fixed frame. A scraper that is slidably disposed on the top of the guide plate is fixedly connected between the two sliding shafts.

[0010] As a further optimization of this utility model, multiple filter plates are slidably arranged between the two slide rods, and water outlet pipes are fixedly connected to both sides of the bottom of the multiple filter plates. A hydraulic cylinder is fixedly connected to the outer side of the second fixed plate, and a pressure plate is fixedly connected to the output end of the hydraulic cylinder.

[0011] As a further optimization of this utility model, a fixed base is fixedly connected to the bottom of the guide plate, and a conveyor belt is fixedly connected to the top of the fixed base.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. When collecting impurities separated by filter press plates, the impurities fall to the top of the guide plate due to their own weight after separation by multiple filter press plates. Since the guide plate is inclined, the impurities will slide onto the conveyor belt. When there are impurities remaining on the guide plate, the cylinder is activated, driving the fixed frame to reciprocate, which drives the sliding shaft to slide in the chute and links the scraper to clean the guide plate. The guide plate can guide the conveyor belt and buffer the impact of falling impurities, avoiding conveyor belt failure due to long-term impact and extending its service life. At the same time, the scraper cleaning ensures that the device is clean.

[0014] 2. When the collection container needs to be disassembled and assembled, the container end with the limiting plate should be aligned with the limiting groove of the first fixing plate and slid in. Then, the container should be aligned with the mounting groove of the second fixing plate and slid in to complete the initial positioning. Then, the baffle should be slid into the fixing groove of the two fixing plates and slid to the bottom to block the container and complete the fixation. To disassemble, the baffle should be removed first, and then the container can be taken out. The disassembly and assembly are simple and convenient for maintenance. The baffle can intercept the liquid discharged from the filter plate to avoid environmental pollution. The liquid is collected by the container and discharged from the drain pipe.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example

[0024] like Figure 1As shown, a filter press for environmental protection engineering includes a transmission pipe 1, which is used to transport the material to be filtered, providing raw materials for the filtration process. A fixing plate 2 is fixedly connected to the output end of the transmission pipe 1, providing fixed support for the transmission pipe 1 and ensuring that the transmission pipe 1 is installed stably. Two sliding rods 3 are fixedly connected to the outer side of the fixing plate 2, providing outward support structure for the fixing plate 2, facilitating the installation of subsequent components. A fixing plate 4 is fixedly connected to the other end of the two sliding rods 3, providing end fixation for the sliding rods 3 and keeping the sliding rods 3 stable. Multiple filter plates 5 are slidably arranged between the two sliding rods 3, and the filter plates 5 can slide along the sliding rods 3, facilitating mutual compression.

[0025] like Figure 1 , Figure 2 As shown, multiple filter plates 5 are fixedly connected to water outlet pipes 6 on both sides of their bottom. The water outlet pipes 6 are used to discharge the liquid separated by the filter plates 5. A hydraulic cylinder 7 is fixedly connected to the outside of the fixed plate 4. In this utility model, the hydraulic cylinder 7 adopts the Rexroth HS series and can be replaced according to the actual situation. The hydraulic cylinder 7 provides the mounting base for the power components of the fixed plate 4. The output end of the hydraulic cylinder 7 is fixedly connected to a pressure plate 8. The pressure plate 8 can move under the drive of the hydraulic cylinder 7, pushing the filter plates 5 closer together. A fixed base 11 is fixedly connected to the bottom of the guide plate 1003. The fixed base 11 provides bottom support for the guide plate 1003. A conveyor belt 12 is fixedly connected to the top of the fixed base 11. The conveyor belt 12 can receive materials on the top of the fixed base 11 to realize the transfer of impurities.

[0026] like Figures 2 to 5 As shown, drainage components 9 are provided on both sides of the fixed plate 2. The drainage components 9 are used to collect the liquid inside the fixed plate 2 to prevent the liquid from flowing out. The drainage components 9 include two collection containers 901, which can hold the liquid within the range of the drainage components 9 to achieve liquid concentration. The outer sides of the two collection containers 901 are simultaneously slidably disposed on the inner sides of the fixed plate 2 and the fixed plate 4. The inner side of the fixed plate 4 has two mounting grooves 905. The outer contour of the mounting grooves 905 is the same as that of the collection containers 901. During assembly, the collection containers 901 are slid horizontally into the mounting grooves 905 for installation. The groove 905 provides a space for the inner side of the fixing plate 2 4 to facilitate the placement of the collection container 901. The outer sides of the two collection containers 901 are slidably set inside the mounting groove 905. The outer sides of the two collection containers 901 are fixedly connected to the limiting plate 902, which restricts the movement of the collection container 901. The inner side of the fixing plate 2 has two limiting grooves 904. The limiting grooves 904 have a convex shape. After the limiting plate 902 is inserted horizontally, the initial limiting and fixing is achieved. The limiting grooves 904 provide positioning space for the inner side of the fixing plate 2 to prevent the collection container 901 from shifting vertically.

[0027] like Figures 2 to 5 As shown, the outer sides of the two limiting plates 902 are inserted into the inner side of the limiting groove 904. The bottom end of the collection container 901 is fixedly connected to a drain pipe 903, which can drain the liquid in the collection container 901 for subsequent processing. The outer side of the collection container 901 is abutted by a baffle 907, which can hold the collection container 901 in place to prevent it from sliding. The outer sides of the two baffles 907 are slidably set inside the two fixing grooves 906. The upper half of the fixing groove 906 allows the baffle 907 to slide horizontally, and the lower half of the fixing groove 906 allows the baffle 907 to be inserted downwards. The inner sides of the fixing plate 1 2 and the fixing plate 2 4 are provided with four fixing grooves 906, which provide grooves for the inner sides of the fixing plate 1 2 and the fixing plate 2 4 to facilitate the installation of the baffles 907.

[0028] like Figure 1 , Figure 6 As shown, a material guiding assembly 10 is provided at the bottom of the fixed plate 1 2. The material guiding assembly 10 is used to guide impurities at the bottom of the fixed plate 1 2 and prevent impurities from scattering. The material guiding assembly 10 includes two side plates 1001. The side plates 1001 provide support on both sides of the material guiding assembly 10 to form a material guiding space. The tops of the two side plates 1001 are fixedly connected to the bottom of the fixed plate 1 2 and the fixed plate 2 4. The inner side of the two side plates 1001 is provided with a sliding groove 1002. The sliding groove 1002 provides a sliding channel for the inner side of the side plates 1001 to facilitate the movement of subsequent components. The bottom of the two side plates 1001 is fixedly connected with a material guiding inclined plate 1003. The material guiding inclined plate 1003 can receive impurities at the bottom of the side plates 1001 and guide the impurities to slide down.

[0029] like Figure 6 As shown, a cylinder 1004 is fixedly connected to the bottom of the guide plate 1003. In this utility model, the cylinder 1004 adopts the SMCCDM2 series and can be replaced according to the actual situation. The cylinder 1004 provides a power source for the bottom of the guide plate 1003 and can output driving force. A fixed frame 1005 is fixedly connected to the output end of the cylinder 1004. The fixed frame 1005 can bear the power of the cylinder 1004 and drive the movement of subsequent components. Two sliding shafts 1006 are fixedly connected to the inner sides of both ends of the fixed frame 1005. The sliding shafts 1006 can move with the fixed frame 1005 to realize sliding action. The outer side of the sliding shafts 1006 is slidably set on the inner side of the slide groove 1002. A scraper 1007 is fixedly connected between the two sliding shafts 1006. The scraper 1007 can move with the sliding shafts 1006 to realize scraping action. The bottom of the scraper 1007 is slidably set on the top of the guide plate 1003.

[0030] It should be noted that in this type of filter press used in environmental engineering, when collecting impurities separated by the filter plates 5, multiple filter plates 5 separate. At this time, the impurities separated between the multiple filter plates 5 naturally fall to the top surface of the guide plate 1003 due to their weight. Because the guide plate 1003 is inclined, the impurities will slide down onto the conveyor belt 12. When there are impurities remaining on the guide plate 1003, the cylinder 1004 is activated, driving the fixed frame 1005 to move linearly and repeatedly. The fixed frame 1005 drives the sliding shaft 1006 to slide inside the sliding groove 1002, and at the same time drives the scraper 1007 to move on the guide plate 1003. 3. The top surface slides, and the scraper 1007 repeatedly slides on the top surface of the guide plate 1003 to clean the impurities remaining on the surface of the guide plate 1003. The guide plate 1003 guides the conveyor belt 12 and prevents the conveyor belt 12 from being impacted by the falling impurities, avoiding failure of the conveyor belt 12 due to long-term impact and extending the service life of the conveyor belt 12. The cylinder 1004 drives the fixed frame 1005, which drives the sliding shaft 1006 to drive the scraper 1007 to perform the final cleaning of the impurities remaining on the guide plate 1003, ensuring the cleanliness of the device.

[0031] When it is necessary to disassemble and assemble the collection container 901, slide the end of the collection container 901 with the limiting plate 902 into the limiting groove 904 opened on the inner side of the fixing plate 1 2, and slide the collection container 901 into the mounting groove 905 opened on the inner side of the fixing plate 2 4 to complete the initial installation. Then slide the baffle 907 into the fixing groove 906 opened on the fixing plate 1 2 and the fixing plate 2 4. The baffle 907 slides to the bottom of the fixing groove 906 to block the collection container 901 and fix the collection container 901, thus completing the final installation. When disassembling, first remove the baffle 907. Disassembly is completed by sliding the collection container 901 out of the fixed groove 906. The disassembly and assembly are simple and convenient for maintenance of the collection container 901. The collection container 901 is initially limited by sliding into the limiting groove 904 through the limiting plate 902, and then finally limited by sliding into the fixed groove 906 through the baffle 907, thus fixing it. At the same time, the baffle 907 intercepts the liquid discharged from the outlet pipe 6 when the filter plate 5 separates the liquid, preventing the liquid from polluting the working environment. The liquid is collected in the collection container 901 and discharged from the drain pipe 903.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
