Technical Field

[0001] This utility model relates to the field of granulation equipment technology, and in particular to a cleaning device for the discharge port of granulation equipment. Background Technology

[0002] Granulation is the process of processing materials in the form of powder, molten liquid, or aqueous solution into granules of a certain shape and size.

[0003] In the high-shear granulation process, the screen inside the granulation cylinder uses a scraper to squeeze and screen the pre-treated wet granules into particles of appropriate size. This method is mostly a sealed operation. After a period of use, the screen needs to be disassembled, cleaned and maintained to ensure normal granulation output from the screen and granulation cylinder. However, the disassembly and cleaning process is cumbersome, time-consuming and labor-intensive, affecting the operation of the equipment.

[0004] To address the aforementioned issues, a cleaning device for the discharge port of a pelletizing equipment is proposed. Utility Model Content

[0024] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0025] like Figures 1-4 As shown in the figure, this embodiment provides a granulation equipment outlet cleaning device, including a granulation cylinder 1, a lower conical structure for discharging formed at the bottom of the granulation cylinder 1, and an upper conical structure for feeding detachably provided at the top of the granulation cylinder 1. The device is characterized in that: a granulation screen 3 is provided inside the granulation cylinder 1 and is detachably connected to the bottom of the upper conical structure; cleaning mechanisms 4 are provided on the outer wall of the granulation screen 3 and the inner wall of the lower conical structure; a power unit 2 is installed between the cleaning mechanisms 4; the power unit 2 includes a support tube frame 201 fixed through the granulation cylinder 1, and a sealed transmission cover 202 is integrally installed at one end inside the support tube frame 201; the cleaning mechanism 4 includes a first driving disc 401 rotatably mounted on the top of the sealed transmission cover 202 and a second driving disc 403 rotatably mounted on the bottom; a first cleaning brush 402 is fixed on the first driving disc 401, and a second cleaning brush 404 is fixed on the second driving disc 403.

[0026] In the above structure, the support tube frame 201 supports and fixes the sealed transmission cover 202, so that the internal transmission components can rotate stably.

[0027] An external drive motor is rotatably mounted inside the support tube frame 201, and a main bevel gear 203 is nested at one end of the drive shaft inside the sealed transmission cover 202.

[0028] The first transmission bevel gear 204 and the second transmission bevel gear 205 are sequentially meshed on the upper and lower sides of the main bevel gear 203. The first drive shaft 206 is keyed to the shaft center of the first transmission bevel gear 204, and the second drive shaft 207 is keyed to the shaft center of the second transmission bevel gear 205. The first drive shaft 206 and the second drive shaft 207 are mounted in the upper and lower walls of the sealed transmission cover 202 by ball bearings for rotatability. They can be driven to rotate by the main bevel gear 203 in the middle.

[0029] The first drive shaft 206 passes through the top wall panel of the sealed transmission cover 202 and the bottom wall panel of the granulation screen 3, and is rotatably mounted with both. The first drive disc 401 is fixedly sleeved on the first drive shaft 206. The first drive shaft 206 rotates in contact with the outer bottom of the granulation screen 3. The granulation screen 3 is fixed to the inner bottom of the granulation cylinder 1. Therefore, the first drive shaft 206 can rotate stably inside after passing through the bottom of the granulation screen 3 through the bearing components. The granulation screen 3 is a fixed structure, and the first drive disc 401 is the drive unit on the first drive shaft 206.

[0030] The second drive disc 403 is fixedly sleeved on the second drive shaft 207 and rotates in contact with the bottom of the sealed transmission cover 202. The second cleaning brush 404 is made of stainless steel and has strong support. It can keep the inner wall of the lower cone clean during rotation.

[0031] The first cleaning brush 402 has a deformable serrated brush formed on the side that contacts the granulation screen 3. A track groove 101 is provided between the top of the first cleaning brush 402 and the granulation cylinder 1. The track groove 101 serves to limit and guide the rotation of the first cleaning brush 402. The tip of the serrated brush can be squeezed out by deformation after being inserted into the mesh of the screen.

[0032] The first drive shaft 206 has granulation scrapers 5 fixed on both sides of one end inside the granulation screen 3. The granulation scrapers 5 slide against the inner wall of the granulation screen 3 and maintain an angle difference of 5-10° with the first cleaning brush 402. This setting is to avoid affecting the extrusion of granules by the granulation scrapers 5 during the granulation process.

[0033] The working principle of this device is as follows:

[0034] When this device is in use, the upper conical opening of the granulation cylinder 1 is used to receive the pre-treated wet granular raw material. The granulation screen 3 is sealed and fixed to the bottom of the upper conical opening by multiple sets of screws. The first drive shaft 206 in the inner wall drives the two sets of granulation scrapers 5 to rotate. The wet granular material is pushed against the inner wall of the screen and squeezed and sheared through the screen holes. Particles or small clumps with a size smaller than the screen hole diameter pass through the screen holes. Particles or solid clumps with a size larger than the screen hole diameter are repeatedly squeezed, rolled and sheared by the scrapers and broken into smaller fragments until they are small enough to pass through the screen holes and are discharged from the lower conical opening at the bottom of the granulation cylinder 1.

[0035] At the same time, the first drive shaft 206 also drives the first drive disc 401 at the bottom of the granulation screen 3 to rotate, and drives the two sets of first cleaning brushes 402, which are close to the outer wall of the granulation screen 3 and have an angle difference of 5-10° with the granulation scraper 5, to rotate, cleaning and brushing the outer wall of the granulation screen 3. The deformable brush tip of the first cleaning brush 402 can be squeezed into the screen hole, pushing the wet material remaining in the screen hole to the inside, avoiding clogging the screen hole, while continuing to be shaped and squeezed into granules by the granulation scraper 5.

[0036] The second drive shaft 207 drives the second drive disc 403 to rotate. The second drive disc 403 drives the two sets of second cleaning brushes 404 that are close to the inner wall of the lower cone of the granulation cylinder 1 to rotate, cleaning and scraping the discharge port to prevent the accumulation of wet granules at the discharge port and affect normal discharge.

[0037] By adopting the above structure, the frequency of disassembly, cleaning and maintenance of the equipment can be reduced, the maintenance difficulty can be reduced, and the efficient production operation of the equipment can be guaranteed.

[0038] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.

[0039] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
