Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filter cake processing, in particular to a transfer device for filter cake waste residue. Background Art
[0002] If the filter cake is too thick during the filter press process, it is necessary to separate and collect the filter cake. Usually, after the suspension containing solid particles enters the filter press, the liquid is forced through the filter medium (such as filter cloth) by the action of pressure to intercept the solid particles and eventually form a filter cake of a certain thickness and weight. After the filter cake is separated, it is usually collected at the bottom using a collection tank or collection pool. These containers are usually fixed, and then moved to the target container through other facilities such as transfer vehicles, troughs, conveyor belts, etc. for the next step of processing, such as drying, etc., and usually needs to be crushed. Since the filter cake can still maintain a certain thickness and shape (large flat cake shape) after separation, and the sizes are different after falling, it is not easy to transfer. If a transfer tool is used, the efficiency is low and it is very labor-intensive. Utility Model Content

[0021] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.
[0022] It includes a spiral conveying mechanism located at the bottom, and the spiral conveying mechanism includes a casing 1. The upper part of the casing 1 is provided with an open opening structure 2, and the width of the opening structure 2 is adapted to the width of the casing 1. A shaft rod that is rotatably installed and driven by a motor is passed through the casing 1, and the shaft rod is provided with spiral blades. The directional pushing of the material is achieved based on the rotation of the shaft rod. A discharge port 3 is provided at the bottom of one end of the casing 1, and a belt conveying mechanism is provided below the discharge port 3. The belt conveying mechanism includes a directionally rotating conveyor belt for directionally conveying the material to the target position, and one end of the conveyor belt is located below the discharge port 3.
[0023] Based on the above structure, two-stage transportation of materials is achieved.
[0024] A crushing mechanism is provided above the spiral conveying mechanism, and the crushing mechanism includes a hopper, and the hopper includes an integrally formed receiving hopper 4 and a dropping hopper 5, and the dropping hopper 5 is a straight cylindrical and vertically extending channel, and the cross-section of the dropping hopper 5 is rectangular, and the bottom end of the dropping hopper 5 is provided with a rectangular dropping port 6, and the dropping port 6 is rectangular, and the width of the dropping port 6 corresponds to the width of the open structure 2, and the length of the dropping hopper 5 is less than the length of the open structure 2 of the casing 1, and one end of the dropping port 6 is aligned with one end of the open structure 2. In this example, the length of the dropping port 6 is 1 / 3 of the length of the open structure 2, so that the material dropped from the dropping hopper 5 can be received by the open structure 2 and conveyed forward a certain distance, so as to ease and stabilize the material during transportation.
[0025] The receiving hopper 4 is a trumpet-shaped structure with a larger upper portion and a smaller lower portion. The bottom side of the receiving hopper 4 is connected to the top side of the dropping hopper 5 to enable the received filter cake to be introduced into the dropping hopper 5 and then centrally introduced into the spiral conveying mechanism through the dropping hopper 5.
[0026] The receiving hopper 4 has a large opening, which can easily receive the fallen large pieces of filter cake and prevent the filter cake from falling outside.
[0027] A first rotating shaft 7 and two second rotating shafts 10 are rotatably installed on the upper part of the dropping hopper 5. The axial directions of the first rotating shaft 7 and the second rotating shaft 10 correspond to the width direction of the dropping hopper 5. The first rotating shaft 7 is centrally arranged in the center of the length direction of the dropping hopper 5, and the second rotating shafts 10 are symmetrically arranged on both sides of the first rotating shaft 7.
[0028] A first hammer handle 8 is fixed in the center of the first rotating shaft 7, and a large hammer 9 is fixed at the end of the first hammer handle 8. A second hammer handle 11 is fixed in the center of the second rotating shaft 10, and a small hammer 12 is fixed at the end of the second hammer handle 11.
[0029] The first hammer handle 8 is longer than the second hammer handle 11. The large hammer 9 and the small hammer 12 are different in size but identical in shape, and each includes a transverse striking tooth 13 and an oblique striking tooth 14 symmetrically arranged on either side. The transverse striking tooth 13 extends to both sides, and the oblique striking tooth forms an acute angle with the transverse striking tooth 13, thereby achieving crushing of filter cakes at different positions and angles during the swinging motion.
[0030] Based on the synchronous rotation of the first rotating shaft 7 and the second rotating shaft 10, the first hammer handle 8 and the second hammer handle 11 swing synchronously in parallel to the left and right, and the swing amplitude is within the range of 180 degrees above the drop hopper 5, and does not exceed 90 degrees on either side, thereby breaking up large flat filter cakes and allowing them to fall into the drop hopper 5, and then be further crushed and transported by the spiral.
[0031] One end of the first rotating shaft 7 is provided with an outer pulley 15 located outside the dropping hopper 5, and one end of the second rotating shaft 10 is provided with a middle pulley 16 located outside the dropping hopper 5. A tensioning pulley 17 is provided between the outer pulley 15 and the middle pulley 16 and is rotatably installed relative to the dropping hopper 5. The tensioning pulley 17 is installed below the outer pulley 15 and the middle pulley 16. A driving pulley 18 driven by a motor is rotatably installed at the lower part of the dropping hopper 5. A transmission belt 19 is wound around the driving pulley 18, the tensioning pulley 17, the outer pulley 15 and the middle pulley 16 to realize synchronous driving of the first rotating shaft 7 and the second rotating shaft 10.
[0032] Based on the above structure, the following actions are performed for receiving and transporting the filter cake:
[0033] When the filter cake falls off the filter cloth, it is in the form of a large plate and is received by the receiving hopper 4 with a large opening. It is broken into small pieces by the left and right blows of the large hammer 9 and the small hammer 12, so that it can fall smoothly into the drop hopper 5. Based on the difference in the size of the hammers and the difference in the length of the first hammer handle 8 and the second hammer handle 11, the filter cake crushing in a wider range can be taken into account. For example, the second hammer handle 11 can take care of the crushing of the filter cake in a small range around it, and the first hammer handle 8 can take care of the crushing of larger filter cakes stuck at a higher position. Then, through multi-dimensional crushing, the volume of the filter cake can be initially reduced. After entering the spiral conveying mechanism through the drop hopper 5, it is pushed by the spiral blades to achieve directional conveying while further balancing the size of the filter cake fragments. The small pieces of filter material can be easily conveyed to the next process through the belt conveyor, thereby solving the problem of transfer and greatly reducing the participation of labor, and taking into account pre-crushing, which provides convenience for the subsequent post-processing of large pieces of filter cake.
