Description

Technical Field

[0001] This invention relates to the field of solid-liquid separation technology, specifically to an intelligent horizontal filter press auxiliary cake unloading device. Background Technology

[0002] In various industrial and public sectors such as chemical engineering, hydrometallurgy, and environmental protection, solid-liquid separation is a core and critical process that runs through the entire production process, ensuring product quality, achieving pollutant discharge standards, or recycling resources. Efficient solid-liquid separation methods enable the recycling of solid and liquid materials, and the effectiveness of solid-liquid separation directly impacts the operational efficiency, product purity, and environmental compliance of subsequent processes.

[0003] Currently, in solid-liquid separation operations, plate and frame filter presses have become one of the most widely used mainstream equipment due to their relatively simple structure, low manufacturing cost, wide applicable material viscosity range, and ability to withstand high filtration pressure. This type of equipment uses alternating filter plates and filter cloths to form filtration chambers. A hydraulic system presses the filter plate assembly, causing the material to pass through the filter cloth under pressure, achieving solid-liquid separation. The solid phase is retained to form a filter cake, while the liquid phase flows out through the filter cloth, completing the filtration process.

[0004] However, as industrial production develops towards higher efficiency, intelligence, and energy conservation, existing plate and frame filter presses have gradually revealed many insurmountable technical defects, such as the need for manual removal of the filter cake remaining between the filter chambers after solid-liquid separation and the need for manual replacement and maintenance of the filter plates in the filter plate assembly, which are not automated.

[0005] The aforementioned problems, when addressed manually, increase the labor intensity for workers. Furthermore, manual removal of the filter cake and replacement of filter plates inevitably result in cake breakage and dispersion, leading to unsatisfactory occupational health conditions on-site. Moreover, long-term exposure to toxic and harmful acid fumes and heavy metal-containing dust released during the wet metallurgical acid leaching process in solid-liquid separation operations can be harmful to human health and detrimental to workers' daily work.

[0006] Chinese patent CN217511251U discloses a filter press with a vibration effect. The filter plate is lifted upward by a mechanical device, and then the lifting cylinder retracts downward. The reaction force of the extension spring causes the filter plate to vibrate up and down, shaking the filter cake off, thus achieving an automatic cleaning effect.

[0007] Chinese patent CN218106856U discloses a blowing system for automatically unloading filter cake in an auxiliary filter press. By changing the form of liquid discharge from the filter plate and reducing the filtrate outflow time, a blowing function is added to the filter cake on the basis of membrane plate pressing, which further reduces the moisture in the filter cake. The filter cake becomes dry and easy to fall off, reducing the adhesion between the filter cake and the filter cloth, and realizing automatic filter cake detachment.

[0008] The above two methods are relatively easy to implement for granular materials with low viscosity, but they are not suitable for solid-liquid separation of highly viscous materials, such as iron oxide and alumina in hydrometallurgical processes. In production practice, manual cake removal is still the preferred method. Furthermore, vibrating the filter cake remover generates significant noise and affects the lifespan of the filter plates.

[0009] Chinese patent CN213942222U discloses an automatic filter cake scraper device for a filter press. This method imitates the manual cake scraping method. A frame support is installed above the filter press, and a movable scraper device is installed on the support. The scraper is moved up and down to scrape off the filter cake by an electric cylinder.

[0010] However, the above method has a fixed movement trajectory of the scraper during the cake removal process, which can remove materials with low viscosity, but it is not effective for viscous materials. In addition, filter cake will remain at the corners of the filter plate during the operation. At the same time, the installation of the frame support makes it inconvenient to replace the filter cloth and filter plate.

[0011] Therefore, the above-mentioned methods of shoveling cake cannot completely replace manual labor and will waste a lot of operating time, which will reduce the production efficiency of the filter press. Moreover, they do not have the function of eliminating the hidden dangers of toxic and harmful vapors and dust to workers on site. Summary of the Invention

[0012] To address the aforementioned issues, an intelligent auxiliary cake unloading device for horizontal filter presses is provided. This device utilizes a robotic arm to thoroughly clean the filter cake from the filter plates without any blind spots. The cleaning process occurs during the pause between the filter plates opening and closing, minimizing additional cycle time and reducing productivity. The device, in conjunction with the collection hood assembly, vertical plate, and exhaust pipe, collects and centrally processes harmful vapors and dust, preventing personnel from prolonged close exposure to hazardous gases, protecting their health, reducing labor intensity, and preventing corrosion of workshop equipment and electrical systems by acidic vapors. Furthermore, the robotic arm's hand is equipped with hooks to replace overhead cranes, facilitating the replacement of filter plates and filter cloths.

[0018] Preferably, the cover is made of an acid-resistant, alkali-resistant, high-temperature and low-temperature resistant, and airtight plastic film or fabric, and both the push-pull telescopic door frame and the cover are inverted "U" shaped.

[0019] Preferably, the longest length the robotic arm extends between the two filter plates is the side length of the filter plate, and the highest height the robotic arm reaches after being raised is greater than the height of the filter press body plus the height of the filter plate plus 5cm to 10cm.

[0020] Preferably, the hand and hook of the robotic arm are made of acid-resistant, alkali-resistant, and temperature-resistant materials such as polytetrafluoroethylene plastic, engineering plastics, and nylon.

[0035] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0036] See Figure 1 , Figure 2 and Figure 4 As shown, an intelligent auxiliary cake unloading device for a horizontal filter press is used to remove the filter cake and its residue from the surface of the filter plates and filter cloth of the horizontal filter press after solid-liquid separation. The device includes: Filter press body 1; Two robotic arms 2 are provided and can move on the outside of the filter press body 1 along the distribution direction of the filter plates. The two robotic arms 2 are respectively located on both sides of the filter press body 1 and are symmetrically arranged about the central axis of the filter plates. The robotic arms 2 have shovel-shaped hands.

[0037] It should be noted that the shovel-shaped hand of robotic arm 2 is the scraper head used to scrape and clean the surface of the filter plate and filter cloth. Robotic arm 2 has the advantages of flexible rotation angle and targeted operation on corners and gaps. Therefore, using it for filter cake scraping can improve the operating range of the filter cake and increase the flexibility of the cake unloading operation.

[0038] The robotic arm 2 is a six-axis robotic arm that can perform set actions in 360°, and the hand shape of the robotic arm 2 is a round or square shovel-shaped structure.

[0039] See Figure 4 and Figure 7 As shown, the side of the hand is provided with a hook 2a that serves to clean and assist in replacing the filter plate and filter cloth, and the back of the hand is evenly provided with cleaning nozzles 2b for cleaning the surface of the filter plate and filter cloth.

[0040] It should be noted that the hook 2a is designed so that the robotic arm 2 can clean the residue in the gaps or corners through the hook, and at the same time facilitate the subsequent replacement of filter plates and filter cloths.

[0041] The cleaning nozzle 2b is used to assist the hand of the robotic arm 2 and the hook 2a in thoroughly cleaning the surface of the filter plate and filter cloth.

[0042] See Figure 1 and Figure 2As shown, the collection hood assembly 3 is installed on the outside of the filter press body 1 and has a movable end and a fixed end. The fixed end is located at the tail of the filter press body 1 and is connected to a vertical plate 3a.

[0043] An exhaust pipe 3b is provided on the side of the upright plate 3a away from the collection cover assembly 3, and the upright plate 3a is provided with a slot that is tightly connected to the inlet end of the exhaust pipe 3b.

[0044] It should be noted that the end of the exhaust pipe 3b is connected to the inlet pipe of the exhaust gas treatment system. The collection hood assembly 3 is used to cooperate with the vertical plate 3a and the exhaust pipe 3b at the vertical plate 3a to cover and collect the gas and dust generated during the working process and cake unloading process of the filter press body 1, and to guide the collected gas and dust to the exhaust gas treatment system for treatment through the exhaust pipe 3b and the inlet pipe.

[0045] See Figure 2 As shown, a pneumatic triplet integrated control box 2c that cooperates with the cleaning nozzle 2b is installed on the side of the upright plate 3a away from the collection hood assembly 3.

[0046] It should be noted that the pneumatic triplet integrated control box 2c purifies and stabilizes the compressed air as needed, which can provide the cleaning nozzle 2b with an air source that meets the working conditions. The two work together to achieve stable and controllable purging of the cleaning nozzle 2b.

[0047] The pneumatic triplet integrated control box 2c is installed on the side away from the collection hood assembly 3 via the vertical plate 3a for easy operation and subsequent maintenance.

[0048] See Figures 1 to 6 As shown, the bottom of the robotic arm 2 is provided with a guide rail 4 to guide its movement position, and the bottom of the upright plate 3a is fixedly connected to the upper surface of the guide rail 4. The bottom of the robotic arm 2 is fixedly connected to a slide block 5 that is slidably connected to the guide rail 4.

[0049] It should be noted that the guide rail 4 includes a track and a cover plate covering the upper side of the track. The track is recessed inward to form a strip-shaped groove. The slide 5 is equipped with a drive device with a vertically downward rotating end. The cover plate has a guide groove that communicates with and penetrates vertically through the strip-shaped groove. The rotating end of the drive device extends vertically to pass through the guide groove and is equipped with a transmission gear. The side wall of the groove is connected to a rack that cooperates with the transmission gear.

[0050] During operation, the rotating end of the drive device drives the transmission gear to rotate and mesh with the rack on the side wall of the groove. At the same time, under the guidance of the track and the cover plate, the slide 5 can drive the robot arm 2 to move along the predetermined direction and position.

[0051] The slide 5 can drive the robot arm 2 to slide along the guide rail 4, which further facilitates the cleaning of the filter plate and filter cloth by the robot arm 2.

[0052] The slide 5 is also provided with track brushes on both sides for cleaning the surface of the guide rail 4 so that it can move smoothly along the guide rail 4.

[0053] See Figure 1 , Figure 3 and Figure 5 As shown, the collection cover assembly 3 is telescopic, and the movable end of the collection cover assembly 3 is connected to the slide 5.

[0054] It should be noted that the collection hood assembly 3 can move synchronously with the slide 5 and the robotic arm 2, which not only facilitates the collection of harmful gases and dust, but also does not affect the subsequent maintenance of the filter press body 1.

[0055] See Figure 1 As shown, a visual locator 6 is also installed on the movable end of the collection cover assembly 3, which is located above the robotic arm 2.

[0056] It should be noted that the visual positioning device 6 is used in conjunction with the slide 5 to control the working position of the robotic arm 2 and the extension and retraction state of the collection hood assembly 3. It also assists the robotic arm 2 in shoveling cake through visual detection. Furthermore, when it is not necessary to assist the robotic arm 2 in shoveling cake, the visual positioning device 6 can also monitor the surrounding environment of the filter press body 1.

[0057] The slide block 5, the robotic arm 2, and the vision positioning device 6 are all linked to the controller of the filter press body 1 and communicate with the central control unit.

[0058] The visual locator 6 can not only locate but also identify the unloading of filter cake and the working conditions related to the actions of the robotic arm 2. Moreover, the positioning and recognition of the robotic arm 2 are generated through optimization after learning from different scenarios.

[0059] See Figure 1 As shown, a warning light 5b is provided on the side of the slide block 5 away from the filter press body 1 to indicate that it is moving.

[0060] It should be noted that a warning light 5b is installed on one side of the slide 5 to remind nearby staff that the machine is in operation, thereby improving safety during operation.

[0061] See Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the collection cover assembly 3 includes: The sliding telescopic door frame 3c has a fixed end and a movable end. The movable end is connected to the slide 5 and is equipped with a visual positioning device 6. The fixed end is connected to the upright plate 3a.

[0062] The overall height of the collection hood assembly 3 is 50cm higher than the top of the filter press body 1; Alternatively, the overall height of the collection hood assembly 3 is 1.5 times the height of the filter plate.

[0063] It should be noted that the sliding telescopic door frame 3c includes several U-shaped door frames and connecting rods that connect the U-shaped door frames. The unfolded length of each connecting rod ranges from 50cm to 100cm.

[0064] See Figure 5 and Figure 8 As shown, the cover 3d is made of a foldable flexible material and is fixedly installed on the inside of the sliding telescopic door frame 3c.

[0065] The cover 3d is made of acid-resistant, alkali-resistant, high-temperature-resistant, and low-temperature-resistant, and airtight plastic film or fabric. The push-pull telescopic door frame 3c and the cover 3d are both inverted "U" shaped.

[0066] The longest length that the robotic arm 2 can extend between the two filter plates is the side length of the filter plate. The highest height that the robotic arm 2 can reach after being raised is the height of the filter press body 1 plus the height of the filter plate plus 5cm to 10cm.

[0067] The hand and hook 2a of the robotic arm 2 are made of acid-resistant, alkali-resistant, and temperature-resistant materials such as polytetrafluoroethylene plastic, engineering plastics, and nylon.

[0068] It should be noted that the above configuration allows the shovel-shaped hand of the robotic arm 2 to remove the filter cake at any angle in the parallel direction of the filter cake.

[0069] See Figure 1 and Figure 2 As shown, a movable filter plate frame 7 is also provided at the end of the filter press body 1 away from the vertical plate 3a. The filter plate frame 7 extends towards the side where the filter press body 1 is located and is provided with a support arm to facilitate the placement of filter plates and filter cloth by the robot arm 2.

[0070] It should be noted that the filter plate holder 7 is used to assist the robotic arm 2 in replacing filter plates and filter cloths. The bottom of the filter plate holder 7 is equipped with rollers, which are placed at the front end of the filter press body 1 when needed, and are placed parallel to the filter plates in the filter press body 1 on the same vertical plane.

[0071] In summary, in specific implementation, when the filter press body 1 is not working, its auxiliary cake unloading device is in the retracted state, and the exhaust system also stops operating. At this time, the visual positioning device 6 only plays the role of monitoring the filter press body 1 and surrounding equipment.

[0072] When the filter press body 1 is started, the collection cover assembly 3 covers the filter plate of the filter press body 1 with the cooperation of the slide 5 and the guide rail 4. At this time, the exhaust system connected to the exhaust pipe 3b also runs at the same time. The whole device plays the role of collecting the volatile gases and dust generated during the operation of the filter press body 1.

[0073] When the filter press body 1 is working, it will transmit the pressure signal generated by the filter press body 1 to the central control. When the set value is reached, the filter press body 1 will stop pressing and switch to the filter cake unloading working state. At this time, the control signal will also be fed back to the vision positioning device 6 for signal feedback and processing. The slide 5 can then move the robot arm 2 to the position of the first filter cake unloading. At the same time, the robot arm 2 starts to scoop the filter cake according to the signal transmitted by the vision positioning device 6.

[0074] When unloading the filter cake, the filter press body 1 will pull apart the first filter plate, and then the filter cake will be unloaded by the robotic arm 2, and so on. At this time, the distance that the filter press body 1 pulls apart the filter plates will not exceed 800mm, and the time interval between pulling apart depends on the viscosity of the filter cake and the cleaning situation.

[0075] After the filter plate is pulled apart, the robotic arm 2, under the command of the vision positioning device 6, will insert its hand between the filter cake and the filter cloth and scrape down the filter cake. After scraping, it will immediately lift up and move to the next filter plate. The time taken is less than 2 seconds, and the whole cycle does not exceed 4 seconds.

[0076] During the cake removal process, if the vision positioning device 6 determines that there is residual filter cake that has not been removed, the cleaning nozzle 2b on the back of the hand can be activated simultaneously to blow compressed air. After the last filter cake is unloaded, the filter press body 1 begins the next round of filtration, and the collection hood assembly 3 moves quickly along the guide rail 4 under the drive of the slide 5 to the dust collection and exhaust working state.

[0077] When a filter plate or filter cloth is damaged and needs to be replaced, the filter press body 1 will pull apart the filter plate and filter cloth that need to be replaced. At the same time, the robot arm 2 will move to the corresponding position. At this time, the robot arm 2 rotates to replace the filter plate. Using the hook 2a of its hand, the target filter plate is lifted to a height higher than the filter press. At the same time, the slide 5 drives the robot arm 2 to move along the guide rail 4 to transfer the filter plate to the filter plate frame 7. The robot arm 2 will lift the pre-prepared filter plate or the filter plate with the new filter cloth from the filter plate frame 7. At the same time, the filter plate with the new filter cloth will be transferred to the original replacement position.

[0078] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
