Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of granulation. More particularly, the present application relates to a granulation device for producing calcium-zinc composite stabilizer. BACKGROUND

[0002] In the processing of calcium-zinc composite stabilizer, the powdery raw materials are often pressed into granules by a roller granulator. The device extrudes the powder into a shape through grooved rollers. However, during the extrusion process, part of the calcium-zinc powder is compacted and adheres to the grooves of the rollers, making it difficult to fall off naturally and forming residual hard blocks.

[0003] When the rollers continue to rotate, these residual hard blocks in the grooves will affect the uniform filling and compaction of the subsequent powder. When extruded again, the newly formed granules cannot fully fill the groove space, resulting in significantly smaller sized and incomplete shaped granules, and even missing granules or failure to form. This seriously affects the continuity and efficiency of the roller granulation, and in turn restricts the production efficiency of the overall granulation process. SUMMARY

[0004] In order to overcome the problem of residual hard blocks in the grooves of the rollers that cannot fall off, thereby interfering with the formation of subsequent granules and leading to a decrease in the efficiency of roller granulation, the present application provides a granulation device for producing calcium-zinc composite stabilizer.

[0006] In addition, it is particularly preferred that the upper part of the guide plate is inclined away from the center of the housing.

[0007] In addition, it is particularly preferred that the device further comprises a circular ring and a driving unit; a circular ring is fixedly connected to each round rod one; the circular ring has elasticity; the active plate is connected with a driving unit, and the driving unit is used to drive the circular ring to rotate.

[0008] Furthermore, particularly preferably, the driving unit comprises a connecting plate one, a cylinder and a screw rod; the connecting plate one is fixedly connected to the shell; a plurality of cylinders are fixedly connected to the connecting plate one; a screw rod is sleeved outside each cylinder; the screw rod is screwed with the corresponding cylinder; each cylinder is rotatably connected with the corresponding movable plate.

[0009] Furthermore, particularly preferably, the driving unit comprises a connecting plate one, a cylinder and a screw rod; the connecting plate one is fixedly connected to the shell; a plurality of cylinders are fixedly connected to the connecting plate one; a screw rod is sleeved outside each cylinder; the screw rod is screwed with the corresponding cylinder; each cylinder is rotatably connected with the corresponding movable plate.

[0010] Furthermore, particularly preferably, the driving unit comprises a connecting plate one, a cylinder and a screw rod; the connecting plate one is fixedly connected to the shell; a plurality of cylinders are fixedly connected to the connecting plate one; a screw rod is sleeved outside each cylinder; the screw rod is screwed with the corresponding cylinder; each cylinder is rotatably connected with the corresponding movable plate.

[0011] Furthermore, particularly preferably, the driving unit comprises a connecting plate one, a cylinder and a screw rod; the connecting plate one is fixedly connected to the shell; a plurality of cylinders are fixedly connected to the connecting plate one; a screw rod is sleeved outside each cylinder; the screw rod is screwed with the corresponding cylinder; each cylinder is rotatably connected with the corresponding movable plate.

[0012] Furthermore, particularly preferably, the shell is provided with a dust collector on the inner side.

[0013] Furthermore, particularly preferably, the shell is coated with a corrosion-resistant layer on the surface.

[0014] Furthermore, particularly preferably, the surface of the movable plate is provided with a smooth surface.

[0015] Beneficial effects: 1. The movable plate is used to move the powder flow, and also drives the cylinder one to move up and down reciprocally, so that the cylinder one can poke and crush the small protrusions remaining in the groove, avoiding the problem of granulation failure caused by the small protrusions remaining in the groove, and the small pieces poked and crushed can participate in the extrusion granulation operation again after moving to the gap between the motor roller one and the motor roller two, avoiding waste and improving economic efficiency.

[0016] 2. The round ring is used to scrape off the small pieces adhering to the groove, avoiding the problem that the small pieces poked and crushed still adhere to the groove and affect the extrusion molding, and the round ring in a circular shape can be fitted to the inner wall of the groove for scraping operation, with high scraping efficiency, and the round ring with elasticity can adapt to elastic deformation when subjected to the thrust of the motor roller two, avoiding interference.

[0017] Third, the ring is supported by the combination of the round rod and the spring, so that the ring can stably crush the small protrusions and avoid incomplete cleaning, thus avoiding the impact on subsequent extrusion molding operations;

[0018] Fourth, by using a combination of baffles and electric rollers, the fragments are pressed into powder and then re-extruded into powder. This avoids the problem of uneven particle density caused by directly extruding powder containing high-density fragments. At the same time, the movable plate used to move the powder flow also drives the electric roller to reciprocate and strike the baffle to generate vibration, which vibrates the fragments to the gap between the baffle and the electric roller and allows them to fully participate in the extrusion. This avoids the problem of extrusion failure caused by the fragments slipping above the gap between the baffle and the electric roller. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0027] Example 1: A granulation device for producing a calcium-zinc composite stabilizer, such as... Figures 1-6 As shown, it includes a shell 1, supports 2, and guide plates 3; four supports 2 are bolted to the shell 1; two symmetrical guide plates 3 are welded to the shell 1; it also includes an electric roller 4, an electric roller 5, a crusher 6, a movable plate 7, an electric push rod 8, and a round rod 9; the electric roller 4 is rotatably connected to the shell 1; the electric roller 5 is rotatably connected to the shell 1; the crusher 6 is installed inside the shell 1, and the crusher 6 is located below the electric roller 4 and the electric roller 5; a movable plate 7 is slidably connected between each guide plate 3 and the shell 1; two electric push rods 8 are fixedly connected to each movable plate 7, and the telescopic ends of the electric push rods 8 are fixedly connected to the corresponding movable plate 7; several round rods 9 are arranged above the electric roller 5, and the round rods 9 are connected to the corresponding movable plates 7; several grooves 91 are opened on the electric roller 5.

[0028] The upper part of the guide plate 3 is inclined away from the center of the outer shell 1, so that the space between the two guide plates 3 is widened, which is conducive to the downward flow of powder.

[0029] It also includes a ring 201 and a drive unit; a ring 201 is welded onto each rod 9; the ring 201 is elastic; the drive unit is connected to the movable plate 7.

[0030] The drive unit includes a connecting plate 202, a cylinder 203, and a lead screw 204. The connecting plate 202 is bolted to the inside of the outer casing 1. Several cylinders 203 are fixedly connected to the connecting plate 202. A lead screw 204 is sleeved on the outside of each rod 9. The lead screw 204 is screwed to the corresponding cylinder 203. The lead screw 204 is made of alloy material. Each rod 9 is rotatably connected to a corresponding movable plate 7. The movable plate 7 drives the rod 9 to move downward. The rod 9 drives the lead screw 204 to move downward inside the cylinder 203, causing the lead screw 204 to rotate. The lead screw 204 drives the rod 9 to rotate. That is, the rod 9 moves downward while rotating.

[0031] It also includes auxiliary components, which include a second round rod 205 and a spring 206; a second round rod 205 is slidably connected to each first round rod 9; a spring 206 is fixedly connected between each second round rod 205 and the corresponding first round rod 9.

[0032] First, calcium-zinc composite powder is manually poured into the cavity between two guide plates 3. The powder flows from the gap between the two movable plates 7 into the cavity above the gap between electric roller 4 and electric roller 5. The electric push rod 8 is then activated, causing the movable plate 7 to reciprocate up and down, continuously shaking the powder above it and increasing its flowability, allowing it to flow smoothly downwards into the cavity above the gap between electric roller 4 and electric roller 5. Electric roller 4 and electric roller 5 are then activated. Looking from front to back, electric roller 4 moves clockwise... As the needle rotates, the electric roller 25 rotates counterclockwise. Through the cooperation of the electric roller 14 and the electric roller 25, the powder located in the gap between them is squeezed and the powder above is continuously moved towards the gap, thereby squeezing the powder into a thin plate. The thin plate has protrusions at the positions corresponding to the groove 91. The electric roller 14 and the electric roller 25 drive the thin plate to move downward to the crusher 6. The crusher 6 crushes the thin plate. Since the gap between the protrusions of the thin plate is relatively thin, the thin plate breaks from the gap between the protrusions, resulting in dispersed small protruding particles.

[0033] During the extrusion process, some small protrusions may detach from the thin plate and remain inside the groove 91, interfering with subsequent extrusion molding operations. Therefore, a circular rod 9 is installed under the movable plate 7 on the right. When the movable plate 7 moves up and down to move the powder, it also drives the circular rod 9 to move up and down. When the groove 91 containing the remaining protrusions moves to below the circular rod 9, the circular rod 9 can break the protrusions. Then, the electric roller 5 continues to rotate, moving the broken pieces in the groove 91 to the gap between the electric roller 4 and the electric roller 5, thereby cleaning the remaining protrusions in the groove 91 and allowing the groove 91 to continue extrusion molding. The extrusion molding operation avoids the problem of granulation failure caused by small protrusions remaining in the groove 91. After the fragments move to the gap between the electric roller 4 and the electric roller 5, they can re-participate in the extrusion granulation operation, avoiding waste. During use, the movable plate 7, which is used to move the powder flow, is also used to drive the round rod 9 to move up and down reciprocally. The round rod 9 breaks up and removes the small protrusions remaining in the groove 91, avoiding the problem of granulation failure caused by small protrusions remaining in the groove 91. After the broken small pieces move to the gap between the electric roller 4 and the electric roller 5, they can re-participate in the extrusion granulation operation, avoiding waste and improving economic efficiency.

[0034] After the round rod 9 breaks up the protruding small pieces, some fragments still stick to the groove 91, interfering with subsequent extrusion molding operations. Therefore, a ring 201 is provided at the lower end of the round rod 9. When the groove 91 with the remaining protruding small pieces moves below the round rod 9, the round rod 9 drives the ring 201 downward, causing the ring 201 to crush the protruding small pieces in the groove 91. At the same time, the movable plate 7 drives the round rod 9 downward, and the round rod 9 drives the lead screw 204 downward within the cylinder 203. The lead screw 204 rotates as it moves downward, driving the round rod 9 to rotate. The round rod 9 then drives the ring 201 to rotate, thus scraping off the fragments remaining in the groove 91 through the rotating ring 201, preventing residue. Furthermore, the circular ring 201 can better fit the groove 91 for scraping, improving scraping efficiency. Furthermore, since the electric roller 201 is in a continuous rotating state, after the ring 201 is attached to the groove 91, during the lifting of the ring 201, the groove 91 of the electric roller 201 will exert a pushing force on the ring 201, resulting in interference. Therefore, the ring 201 is made of an elastic material. When the groove 91 of the electric roller 201 exerts a pushing force on the ring 201, the ring 201 can undergo adaptive elastic deformation to avoid interference. In use, the ring 201 can scrape off the fragments stuck in the groove 91, avoiding the problem that even after the small protrusions are broken, fragments will still stick to the groove 91 and affect the extrusion molding. In addition, the circular ring 201 can fit against the inner wall of the groove 91 for scraping operation, which has high scraping efficiency. Moreover, the elastic ring 201 can undergo adaptive elastic deformation when subjected to the pushing force of the electric roller 25, avoiding interference.

[0035] Making the ring 201 a flexible material would reduce its strength, potentially causing it to fail to crush the small protrusions and resulting in incomplete cleaning. Therefore, an auxiliary component is installed on the first round rod 9. When the first round rod 9 moves the ring 201 downwards to crush the small protrusions, it also moves the second round rod 205 and the spring 206 downwards. At this time, the lower part of the ring 201 is supported by the second round rod 205 and the spring 206, ensuring that the ring 201 can stably crush the small protrusions and preventing incomplete cleaning. To address the issue of incomplete cleaning, when subjected to the thrust of the electric roller 25, the ring 201 undergoes adaptive deformation. The ring 201 drives the rod 205 to move inward towards the rod 9, compressing the spring 206. This also avoids interference. During use, the rod 205 and the spring 206 work together to support the ring 201, enabling it to stably crush the small protrusions and avoid incomplete cleaning, thus preventing any impact on subsequent extrusion molding operations.

[0036] Example 2, based on Example 1, such as Figure 4 and Figure 5As shown, it also includes a crushing assembly, which includes a baffle 207, a connecting plate 208, an electric roller 3 209, and an air jet unit; the electric roller 207 is provided on the outside of the electric roller 2 5, the baffle 207 is fixedly connected to the outer shell 1, and the baffle 207 is made of a rigid material; the connecting plate 208 is provided above the baffle 207, and the connecting plate 208 is fixedly connected to the corresponding movable plate 7; the connecting plate 208 is elastic; the electric roller 3 209 is rotatably connected to the connecting plate 208; and the air jet unit is connected to the guide plate 3.

[0037] The jet unit includes a first pipe 2010 and a second pipe 2011; the first pipe 2010 is installed on the outer shell 1; several second pipes 2011 are fixedly connected to the first pipe 2010 and communicate with it; each second pipe 2011 is fixedly connected to the corresponding guide plate 3.

[0038] A vacuum cleaner is installed inside the outer casing 1 to remove the dust that is stirred up.

[0039] The outer casing 1 is coated with an anti-corrosion layer to prevent rust and extend its lifespan.

[0040] The surface of the active plate 7 is set to be smooth to reduce friction.

[0041] When the crushed small pieces move to the gap between electric roller 4 and electric roller 5 to re-participate in the extrusion granulation operation, the density of the crushed pieces is much greater than that of the surrounding powder. This results in excessively high density of the protruding small pieces formed by the extrusion of the crushed pieces, leading to uneven particle density. Therefore, a crushing component is installed on the outer shell 1. First, an external air supply pipe is manually connected to pipe 1 2010. When the ring 201 crushes and scrapes off the protruding small pieces remaining in the groove 91, air is supplied to pipe 1 2010 through the external air supply pipe. The air flows from pipe 1 2010 into pipe 2 2011, and then is sprayed from pipe 2 2011 into the groove 91, blowing the scraped-off crushed pieces into the cavity formed by the baffle 207, connecting plate 208, and electric roller 3 209. Under the action of force, the fragments are dispersedly accumulated at the angle between the baffle 207 and the electric roller 209. Viewed from front to back, the electric roller 209 rotates clockwise to compress the fragments. Since the fragments accumulated at the angle between the baffle 207 and the electric roller 209 are few in number and relatively dispersed, they can fully extend and diffuse to the surroundings after being compressed, thus compressing them into powder. The powder flows from the gap between the baffle 207 and the electric roller 209 to the gap between the electric roller 4 and the electric roller 5, so that it can be re-extruded into extrusion molding. In use, the baffle 207 and the electric roller 209 work together to roll the fragments into powder, and then make them participate in the extrusion molding operation again, avoiding the problem of uneven particle density caused by directly extruding and molding powder mixed with high-density fragments.

[0042] When the movable plate 7 reciprocates up and down, it also drives the connecting plate 208 to reciprocate up and down. During this process, the connecting plate 208 drives the electric roller 209 to move downwards and contact the baffle 207. The movable plate 7 continues to move downwards, squeezing the connecting plate 208, causing it to undergo adaptive elastic deformation. This fully presses the electric roller 209 against the baffle 207, which helps to improve the squeezing effect on the fragments. When the movable plate 7 moves upwards back to its original position, the connecting plate 208 rebounds, driving the electric roller 209 back to its original position, thus allowing the electric roller 209 to... The reciprocating impact of the baffle 207 generates vibration, which vibrates the fragments towards the gap between the baffle 207 and the electric roller 209, ensuring they fully participate in the compression process and preventing the fragments from slipping above the gap, thus avoiding compression failure. In use, the movable plate 7, used to move the powder flow, also drives the electric roller 209 to reciprocate and impact the baffle 207, generating vibration and vibrating the fragments to the gap between the baffle 207 and the electric roller 209, ensuring they fully participate in the compression process and preventing compression failure caused by the fragments slipping above the gap.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
