Description
Technical Field
[0001] The utility model relates to the technical field of coconut shell processing, in particular to a coconut shell crushing device. Background Art
[0002] Coconut shell activated carbon is a kind of activated carbon made from high-quality coconut shells. Coconut shell activated carbon is black and granular in appearance, with well-developed surface pores and good adsorption properties. It is mainly used for purification of drinking water and pure water, processing of wine, beverages and industrial wastewater, and can also be used in the process of extracting precious metals such as gold.
[0003] Crushing coconut shells is a key step in the production process of coconut shell activated carbon. During the crushing stage, coconut shells are processed into granular form and impurities are removed in the process. At present, the mainstream crushing equipment is a general-purpose roller crusher, which crushes coconut shells through a double-roll extrusion mechanism. However, there is an obvious problem with this crushing method: the size of coconut shell particles is difficult to accurately control. Therefore, the output particles must be screened to ensure that they meet the particle size requirements of subsequent carbonization and activation processes. Unfortunately, a large number of particles are eliminated during the screening process. These eliminated particles are difficult to use to produce high-quality coconut shell activated carbon, resulting in low added value and profits of the product, while reducing the output ratio of high-quality particles. In order to improve the production efficiency and quality of coconut shell activated carbon, we need to explore more precise crushing processes to improve the consistency of particle size and increase the output of high-quality coconut shell activated carbon.
[0004] In view of this, we designed a crushing device that can accurately control the size of coconut shell particles, which is suitable for the mass production of coconut shell activated carbon. Utility Model Content
[0005] The utility model aims to provide a coconut shell crushing device to solve the problems described in the background technology.
[0006] The technical solution of the utility model is achieved in this way:
[0007] A coconut shell crushing device comprises a bottom plate, a first support seat and a second support seat are fixedly arranged on the upper end of the bottom plate, an outer cylinder is fixedly arranged on the first support seat, an inner cylinder is fixedly arranged on the second support seat, an outer cylinder top wall is arranged on the top of the outer cylinder, the bottom of the outer cylinder is open, an inner cylinder top wall is arranged on the top of the inner cylinder, the bottom of the inner cylinder is open, the inner cylinder is arranged inside the outer cylinder, the outer wall of the inner cylinder and the inner wall of the outer cylinder are clamped to form an annular extrusion channel, a ring column pressing block is arranged inside the outer cylinder for sliding up and down, the outer wall of the ring column pressing block is slidably fitted and connected with the inner wall of the outer cylinder, when the ring column pressing block is pressed downward into the extrusion channel, the inner wall of the ring column pressing block is slidably fitted and connected with the outer wall of the inner cylinder, and a pointed tip is arranged on the upper end of the inner cylinder top wall. A cone is formed on the top of the ring column pressure block, and at least two sliding rods are vertically provided on the top of the ring column pressure block, and the sliding rods are slidably penetrated in the top wall of the outer cylinder, and a feeding pipe is fixedly penetrated in the top wall of the outer cylinder just above the center of the cone. A lifting control mechanism for driving the sliding rod to move up and down is also provided on the top of the first support seat, and the lifting control mechanism includes a third support seat fixedly provided on the top of the first support seat, and a top frame is also fixedly provided on the top frame, and at least one pneumatic push rod is also fixedly provided on the top frame, and the telescopic rod of the pneumatic push rod extends vertically downward and is fixedly connected to the top of a sliding rod, and a cutting mesh ring is also detachably installed on the middle and lower part of the extrusion channel, and the cutting mesh ring covers the cross-section of the entire extrusion channel.
[0008] When using the above scheme, coconut shells are put into the feed pipe, and the coconut shells fall along the feed pipe onto the cone, and slide along the conical surface of the cone from all directions into the extrusion channel, and are received by the cutting mesh ring. Then the pneumatic push rod is started, and the pneumatic push rod pushes the ring column pressing block downward. Under the extrusion of the ring column pressing block and the cutting mesh ring, the coconut shells are cut into corresponding sizes according to the mesh size in the cutting mesh ring, and fall out of the outer cylinder through the cutting mesh ring, thereby completing the crushing operation of the coconut shells.
[0009] When the ring column pressing block is pressed into the extrusion channel, the coconut shell is continuously fed and stored on the conical surface of the cone. When the ring column pressing block moves upward, it leaks out of the extrusion channel and falls into the extrusion channel again to complete the filling. The ring column pressing block is pressed down again, and the process repeats in sequence to achieve continuous crushing and mass production.
[0010] By setting the cutting mesh ring, the particle size of the coconut shell after crushing can be controlled by controlling the mesh size of the cutting mesh ring, thereby improving the consistency of the coconut shell particles after crushing and increasing the output of high-quality coconut shell activated carbon. When another type of coconut shell particles needs to be produced, only the cutting mesh ring needs to be replaced. The installation position of the cutting mesh ring is also convenient for the disassembly and assembly of the cutting mesh ring.
[0011] A further technical solution is that the cutting mesh ring comprises an outer ring, a mesh knife and an inner ring, the inner ring is arranged inside the outer ring, and the mesh knife is fixed between the outer ring and the inner ring to cover the clamping space between the outer ring and the inner ring.
[0012] When the above solution is used, the structural strength of the cutting mesh ring is made more stable by setting the structure of the outer ring, the inner ring and the mesh knife.
[0013] A further technical solution is that an annular outer ring groove is provided at the connection between the bottom of the outer cylinder and the inner wall of the outer cylinder, and an annular inner ring groove is provided at the connection between the bottom of the inner cylinder and the outer wall of the inner cylinder. A plurality of threaded holes are provided at the top of the outer ring groove and the top of the inner ring groove. The outer ring of the cutting net ring is arranged in the outer ring groove, and the inner wall of the outer ring is flush with the inner wall of the outer cylinder. The inner ring of the cutting net ring is arranged in the inner ring groove, and the outer wall of the inner ring is flush with the outer wall of the inner cylinder. A plurality of through holes are also provided in the outer ring and the inner ring, which penetrate the outer ring and the inner ring up and down. The outer ring and the inner ring are respectively screwed into the threaded holes of the outer ring groove and the inner ring groove by bolts passing through the through holes.
[0014] When the above solution is used, by setting the outer ring groove, the inner ring groove, the threaded hole and the through hole, the disassembly and assembly of the cutting mesh ring is more convenient and the positioning is more accurate.
[0015] A further technical solution is that the top of the annular column pressing block is also provided with an inclined surface inclined toward the central axis of the outer cylinder.
[0016] When the above scheme is used, the inclined surface is provided to prevent the coconut shell from being left on the top of the ring column pressing block, so that the coconut shell can fall along the inclined surface to the top of the cone.
[0017] A further technical solution is that a motor is fixedly provided at the lower end of the inner tube top wall of the inner tube, and a rotating shaft is fixedly provided at the bottom of the cone. The central axis of the rotating shaft is colinear with the central axis of the cylinder. The rotating shaft is rotatably penetrated in the top wall of the inner tube, and the cone is rotatably installed on the top wall of the inner tube through the rotating shaft. The bottom of the rotating shaft passes downward through the top wall of the inner tube and is driven and connected with the motor.
[0018] When the above solution is used, the cone can be rotated by arranging a motor and a rotating shaft. By driving the cone to rotate, the coconut shells are thrown out from all directions, so that the coconut shells can be more evenly distributed in the extrusion channel.
[0019] A further technical solution is that a plurality of dividing plates distributed at equal angles are fixedly arranged on the conical surface of the cone, and the dividing plates are located within the inner range of the annular column pressing block.
[0020] When the above solution is used, the coconut shell can be further dispersed more evenly by setting a material distribution plate.
[0021] A further technical solution is that a feed hopper is also provided on the top of the feed pipe.
[0022] A further technical solution is that the outer cylinder and the inner cylinder are both cylinders, and the central axis of the outer cylinder and the central axis of the inner cylinder are collinear.
[0023] The beneficial effects of the utility model are:
[0024] 1. Efficient and continuous crushing: The solution realizes continuous crushing and mass production of coconut shells through the design of continuous feeding and reciprocating motion of ring column briquetting, thus improving production efficiency.
[0025] 2.

This design not only improves the consistency of coconut shell particles, but also makes it simple and quick to replace the cutting mesh ring to meet different particle requirements.
[0026] 3. Easy to maintain and replace parts: The design of the outer ring groove, inner ring groove, threaded hole and through hole makes the disassembly and assembly of the cutting mesh ring more convenient and the positioning is accurate, which greatly reduces the difficulty of maintenance and replacement of parts and saves production time and cost.
[0027] 4. Optimized design to prevent residue: The inclined design on the top of the ring column block effectively prevents the coconut shell from remaining on its top, ensuring that the coconut shell can fall smoothly onto the top of the cone, further ensuring the continuity and efficiency of production.
[0028] 5. Evenly distribute coconut shells: The design of the motor, shaft and dividing plate enables the cone to rotate, so that the coconut shells are evenly thrown out from all directions, ensuring that the coconut shells are evenly distributed in the extrusion channel, which is conducive to improving the crushing quality and efficiency.
