Description

Technical Field

[0001] This utility model relates to filter presses, and more particularly to a filter cake breaking device for filter presses. Background Technology

[0002] In chemical production and sludge treatment processes, materials need to be mixed with water and reacted to a certain extent before being separated from the water using plate and frame filter presses. The material forms a filter cake, which is then conveyed to specific equipment for the next process. Because the plate and frame filters are relatively large, the filter cake after pressing needs to be manually crushed, increasing labor costs and affecting work efficiency. Patent document CN201046935Y discloses a sludge filter cake crushing device, which includes a sludge transfer trough at an angle of 10° to 20° to the horizontal ground. A shafted spiral cutter is installed inside the sludge transfer trough, with several serrations distributed on its outer tangential surface. Adjacent serrations form an angle of 30° to 50° in the cross-section. The shafted spiral cutter is driven by a motor; after it starts operating, the serrations on its outer tangential surface gradually break the large pieces of sludge filter cake into smaller pieces. However, this type of filter cake crushing device relies on the rotation of the auger to drive the saw teeth to cut the sludge, which is a passive pulling crushing method. For filter cakes with high viscosity and toughness, it is prone to entanglement and compression into clumps, resulting in poor crushing efficiency and anti-clogging ability. Therefore, it is necessary to optimize its structure to overcome the above-mentioned defects. Utility Model Content

[0011] The advantages of this utility model are: This device adopts the principle of vibration crushing.

The vibrating bearing component is installed in the machine base and can vibrate within the machine base; it has a bearing space inside. The transfer positioning component is installed in the vibrating bearing component and is located between the filter press and the conveying device; it can vibrate together with the vibrating bearing component and has a positioning space inside. The transverse crushing component is installed in the transfer positioning component and can vibrate together with the transfer positioning component. The transverse crushing component crushes the filter cake output from the filter press, causing it to enter the conveying device after crushing. The crushing component is installed in the transfer positioning component and combined with the transverse crushing component. It can vibrate together with the transfer positioning component. The longitudinal crushing component crushes the filter cake output from the filter press and then sends it into the conveying device. The excitation drive component is installed in the transfer positioning component and can run in the transfer positioning component. It drives the transfer positioning component, transverse crushing component, longitudinal crushing component and vibrating bearing component to vibrate together. The residue cleaning component is installed in the machine base through the transfer mechanism and cooperates with the transverse crushing component and the longitudinal crushing component. The moving mechanism drives the residue cleaning component to clean the filter cake residue left in the transverse crushing component and the longitudinal crushing component.

[0015] In this embodiment, the vibration bearing assembly includes a bearing column 110 and a bearing sleeve 120. A set of bearing columns is provided, each bearing column is installed in the machine base and arranged vertically. A set of bearing sleeves is provided, each bearing sleeve is sleeved on the top of the bearing column, and a buffer spring is provided between the bearing sleeve and the bearing column so that the bearing sleeve can vibrate vertically along the bearing column.

[0016] The transition positioning assembly includes a transition frame 200, which is formed by columns and located between the filter press and the conveying device. Each bearing sleeve is connected to the bottom of the transition frame and arranged sequentially along the circumference of the transition frame. The bearing sleeves support the transition frame, allowing the transition frame to vibrate together with the bearing sleeves.

[0017] The transverse crushing assembly includes transverse strips 300. A set of transverse strips is provided. The length direction of each transverse strip extends transversely, and its width direction extends vertically. Both ends of its length direction are respectively connected to the inner wall of the transfer frame.

[0018] The longitudinal crushing component includes longitudinal strips 400, which are arranged in a set. Each longitudinal strip extends longitudinally in its length direction and vertically in its width direction. Its two ends in the length direction are respectively connected to the inner wall of the transfer frame, and its middle part in the length direction is respectively connected to the transverse strips. The longitudinal strips and transverse strips form a rectangular grid, and the transfer frame positions the longitudinal strips and transverse strips so that the transverse strips and longitudinal strips can vibrate together with the transfer frame. When the filter cake falls onto the longitudinal strips and transverse strips, it is cut and crushed by the longitudinal strips and enters the conveying device.

[0019] In this embodiment, the inner wall of the adapter frame has a transverse slot 210 and a longitudinal slot 220. The two ends of the transverse strips are respectively provided with transverse notches 310 that mate with the transverse slots and are fitted into the transverse slots. The two ends of the longitudinal strips are respectively provided with longitudinal notches 410 that mate with the longitudinal slots and are fitted into the longitudinal slots. A receiving slot 320 is provided in the middle of the transverse strips, and a mating slot 420 is provided in the middle of the longitudinal strips. The vibration drive assembly includes a pair of vibration motors 500, each installed on both sides of the transfer frame. When running, the motors can drive the transfer frame to vibrate vertically, thereby accelerating the cutting and crushing process of the filter cake.

[0020] The residual material cleaning assembly includes a cleaning scraper 600, which is installed in the machine via a conveying mechanism. The scraper extends longitudinally in its length direction and vertically in its width direction. Its bottom edge contacts the top of the transverse and longitudinal strips. The conveying mechanism drives the cleaning scraper to move along the top of the transverse and longitudinal strips to scrape off the remaining filter cake residue.

[0021] After the device is started, the excitation motor in the excitation drive assembly runs, driving the transfer positioning assembly, the transverse crushing assembly, the longitudinal crushing assembly, and the vibration bearing assembly to vibrate vertically together. The blocky filter cake output from the filter press falls into the rectangular grid composed of transverse and longitudinal strips, and is immediately subjected to the impact and cutting of the high-frequency vibration of the transverse and longitudinal strips, and is quickly crushed. The crushed filter cake particles fall through the grid gaps under the action of vibration and are transported away by the conveying device below. Vibration continues throughout the crushing process, which both accelerates the crushing and prevents the material from clogging the grid. After unloading or when cleaning is required, the transfer mechanism drives the cleaning scraper in the residual material cleaning assembly to move along the top of the grid, scraping off the filter cake residue left on the transverse and longitudinal strips, keeping the crushing assembly clean, and preparing for the next operation.
