Description

Technical Field

[0001] This utility model relates to the field of granulator technology, and in particular to a granulator with drying and pulverizing functions. Background Technology

[0002] Granulators are widely used in chemical, food, pharmaceutical, and plastics processing industries to process powdered, granular, or processed raw materials into granules of a specific size. In some raw material processing, due to the potential presence of moisture or agglomeration, the raw materials usually require pre-drying and pulverizing to improve their uniformity and make them more suitable for subsequent granulation. Some existing granulators are equipped with drying and pulverizing mechanisms to pre-treat the raw materials before granulation.

[0003] However, in existing granulators with drying and pulverizing functions, raw materials typically enter the equipment directly through the feed hopper. Since large particles may be introduced during storage or transportation, these impurities can easily enter the granulation mechanism along with the raw materials, affecting subsequent processing. Furthermore, the existing filter structure within the feed hopper tends to accumulate impurities after prolonged use. Cleaning or replacement usually requires disassembling multiple components, making the process cumbersome and reducing equipment maintenance efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a granulator with drying and pulverizing functions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A granulator with drying and pulverizing functions includes a granulator and a drying channel on its top. A feed hopper is fixedly installed on the top of the drying channel, and a removable filter screen is installed inside the feed hopper. Multiple positioning columns are fixedly installed inside the feed hopper. Each positioning column has a slot on one side and a locking column is movably installed on the top of each positioning column. Movable plates are installed on both sides of the filter screen, and locking plates and clamping plates that are adapted to the locking columns and slots are fixedly installed on the upper and lower sides of the movable plates, respectively.

[0006] In addition, a preferred structure is that the filter screen has vertically penetrating positioning cavities adapted to the positioning posts at each of its corners, and the bottom surface of the filter screen has a slope adapted to the feed hopper.

[0007] In addition, in a preferred configuration, a fixed seat is provided on both sides of the top of the filter screen, and multiple guide posts are provided on each fixed seat. The movable plate is guided to move by the guide posts, and a second spring is sleeved on the outer side of each guide post. The two ends of the second spring are respectively connected to the fixed seat and the movable plate.

[0008] Furthermore, in a preferred configuration, each of the positioning posts has a spring cavity at its top, and each spring cavity is fitted with a vertically movable locking post via a first spring.

[0009] In addition, a preferred structure is that a locking plate is fixedly provided on the top of each of the movable plates, and the locking plate is provided with a locking hole that matches the locking pin.

[0010] In addition, a preferred structure is that each of the movable plates is fixedly provided with a card plate at its bottom, the card plate is adapted to the card slot, and the bottom of the card plate is provided with a clearance ramp.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-8 A granulator with drying and pulverizing functions includes a granulator 1 and a drying channel 2 on its top. A feed hopper 3 is fixedly installed on the top of the drying channel 2, and a removable filter screen 4 is installed inside the feed hopper 3. Multiple positioning posts 31 are fixedly installed inside the feed hopper 3. A slot 32 is opened on one side of each positioning post 31, and a locking post 34 is movably installed on the top of each positioning post 31. Movable plates 6 are provided on both sides of the filter screen 4, and locking plates 62 and clamping plates 61 that are adapted to the locking posts 34 and slots 32 are fixedly installed on the upper and lower sides of the movable plates 6, respectively.

[0016] The filter screen 4 has a vertically penetrating positioning cavity 41 that is adapted to the positioning post 31 at each corner, and the bottom surface of the filter screen 4 is provided with a slope that is adapted to the feed hopper 3.

[0017] The filter screen 4 has fixed seats 5 on both sides of its top, and multiple guide posts 51 on each fixed seat 5. The movable plate 6 is guided to move by the guide posts 51. A second spring 52 is sleeved on the outside of each guide post 51, and the two ends of the second spring 52 are connected to the fixed seat 5 and the movable plate 6 respectively. Through the cooperation of the guide posts 51 and the second spring 52, the movement of the movable plate 6 can be guided and reset, keeping its structure stable.

[0018] Each positioning post 31 has a spring cavity 33 at its top, and a vertically movable locking post 34 is installed in each spring cavity 33 via a first spring 331. A guide structure, as used in the prior art, can be provided on the locking post 34 to achieve stable movement.

[0019] Each movable plate 6 has a locking plate 62 fixedly installed on its top, and each locking plate 62 has a locking hole 621 that matches the locking post 34. Each movable plate 6 has a locking plate 61 fixedly installed on its bottom, and each locking plate 61 matches the locking groove 32, and each locking plate 61 has a clearance ramp 611 at its bottom.

[0020] It is worth noting that the first spring 331 and the second spring 52 involved in this embodiment are conventional structural components known to those skilled in the art. In specific engineering implementations, technicians can select other elastic elements with equivalent reset functions for equivalent replacement according to the actual assembly conditions, as long as they can remain stable and not easily loosen when providing elastic preload. Further details will not be provided here.

[0021] In this embodiment, the granulator with drying and pulverizing functions operates by using a feed hopper 3 to receive raw materials and a filter screen 4 to intercept and filter impurities in the raw materials. The raw materials are then dried through a drying channel 2 before entering the granulator 1 for granulation. It is worth noting that this specific structure and working principle are existing technologies and will not be described in detail here.

[0022] After prolonged use, when it is necessary to clean or replace filter 4, the user can disassemble and install it.

[0023] When it is necessary to remove the filter screen 4, press down on the locking pins 34 on both sides to compress the first spring 331 and move it downward to exit the locking hole 621, thus releasing the restriction on the locking plate 62. Then pull the movable plate 6 outward. The movable plate 6 moves on the guide pin 51 and compresses the second spring 52, causing the bottom retaining plate 61 to exit from the retaining groove 32. At this time, the filter screen 4 can be taken out upward along the positioning pin 31.

[0024] Furthermore, during the installation of the filter screen 4, the positioning cavity 41 of the filter screen 4 is aligned with the positioning post 31 and lowered into the feed hopper 3. During the descent, the clearance ramp 611 at the bottom of the clamping plate 61 contacts the positioning post 31 and is subjected to force, causing the movable plate 6 to move inward and compress the second spring 52. When the filter screen 4 is in place, the clamping plate 61 aligns with the slot 32, and under the elastic force of the second spring 52, the movable plate 6 returns to its original position, causing the clamping plate 61 to engage with the slot 32. At the same time, the locking hole 621 moves above the locking post 34, and the first spring 331 pushes the locking post 34 upward into the locking hole 621, completing the fixation of the filter screen 4.

[0025] It is worth noting that the locking component of the filter screen 4 in this application consists of components such as the positioning post 31, the fixing seat 5, and the movable plate 6. In the actual manufacturing process, one or two locking components can be set according to the actual working conditions.

[0026] In this utility model, the drying channel 2 and the granulator 1 can realize the drying, crushing and granulation of materials. The feed hopper 3 and the filter screen 4 can intercept impurities in the raw materials. The filter screen 4 can be easily disassembled and assembled by the matching arrangement of the positioning column 31, the movable plate 6, the locking column 34 and the clamping plate 61, so as to improve the maintenance efficiency of the equipment.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
