Description

Technical Field

[0001] This utility model relates to the field of shale ceramsite raw material preparation technology, specifically a shale ceramsite raw material quantitative batching device. Background Technology

[0002] Shale ceramsite is a lightweight aggregate made primarily from shale through a series of processes including crushing, batching, and firing. The performance of shale ceramsite largely depends on its chemical composition. Different chemical compositions affect key indicators such as strength, density, and porosity. Quantitative batching allows for precise control of the proportions of various raw materials, ensuring stable physical and chemical changes during firing and guaranteeing a relatively consistent chemical composition for each batch, thus ensuring product quality stability.

[0003] When materials have high moisture content or contain a lot of fine powder, blockages can easily occur in hoppers, pipes, and other parts. For example, if shale raw materials become damp during storage, they may stick together when entering the hopper of the batching device, causing poor material discharge; material accumulation in pipes can also cause blockages, affecting the normal transport of materials.

[0004] Traditional quantitative feeding operations employ pre-treatment for agglomerated materials. However, due to high humidity, materials may still stick to the feeding area during feeding, leading to accumulation and inaccurate feeding over time. Therefore, this application provides a quantitative feeding device for shale ceramsite raw materials. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a quantitative batching device for shale ceramsite raw materials, which solves the problem that in existing technologies, caking materials may still stick to the distribution area due to their high moisture content, resulting in accumulation in the distribution area and inaccurate material dispensing.

[0006] The present invention relates to a shale ceramsite raw material quantitative batching device, comprising a collection and dispensing component for quantitative dispensing and a dispensing component disposed on the collection and dispensing component;

[0007] The collection and dispensing component includes a base, on which a collection frame is provided, and the collection frame is located below the dispensing component;

[0008] The dispensing component includes a material guiding component, the bottom of which maintains a fixed distance from the collection port of the collection frame. A sliding sealing component is provided on the top of the material guiding component, and a dispensing cylinder is provided on the top of the sliding sealing component. An inner cavity is provided on the inner side of the dispensing cylinder, and a push plate is provided on the inner side of the inner cavity for quantitative dispensing of materials.

[0009] As a further improvement of this utility model, the inner side of the distribution cylinder is provided with an inner cavity, the top of the inner cavity is provided with a feed port, and the bottom is provided with a discharge port, which is adapted to the sliding sealing component.

[0010] As a further improvement of this utility model, a feeding port is provided at the top of the feed inlet of the inner cavity, a drive motor is provided on one side of the feeding port, and a sealing cover is installed on the inner side of the feeding port. The sealing cover is opened and closed by the drive motor.

[0011] As a further improvement of this utility model, one or more through holes extending into the inner cavity are provided on one side of the distribution cylinder. A telescopic component 2 is provided at the through hole. A push plate is installed at one end of the telescopic component 2 in the inner cavity. The push plate slides against the inner wall of the inner cavity.

[0012] As a further improvement of this utility model, a fixed frame and a telescopic component three are provided on one side of the sliding sealing component. The telescopic component three is located on one side of the fixed frame, and a sliding plate adapted to the discharge port is fixed to the piston rod end of the telescopic component three.

[0013] As a further improvement of this utility model, an outer frame is provided on the outer side of the sliding plate, and a cleaning area is provided on the inner side of the outer frame for cleaning the surface of the sliding plate.

[0014] As a further improvement of this utility model, the push plate includes a plate body, and two symmetrically arranged positioning holes are provided on one side contact surface of the plate body. A guide rod for limiting is installed at the positioning hole. An installation hole is provided in the middle of the plate body between the two positioning holes. The installation hole is adapted to one end of the telescopic member two.

[0015] As a further improvement of this utility model, a telescopic component is provided on one side of the collection frame, which is used to push the collection frame to reciprocate linearly along the base.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model uses a push plate guided by positioning holes and guide rods, and with the precise control of the movement by telescopic component two, it can accurately push the shale ceramsite raw material in the inner cavity to the discharge port, achieving highly accurate quantitative distribution and effectively ensuring the accuracy of each batch of material.

[0018] The push plate fits tightly against the inner wall of the cavity and slides smoothly. Its smooth surface treatment and reasonable material selection further ensure the accuracy of the quantitative process, avoid material residue and measurement error. In addition, the funnel-shaped structure and smooth surface of the material guiding component, as well as the polishing treatment of the sliding plate in the sliding sealing component, effectively reduce the adhesion of materials during the conveying process, ensuring that the materials can flow smoothly from the distribution cylinder into the collection frame, preventing blockage problems from affecting the production process.

[0019] Meanwhile, the outer frame and cleaning area on the outside of the sliding plate can automatically clean its surface during the sliding plate's extension and retraction, preventing material adhesion from affecting the sealing performance of the discharge port and the normal operation of the sliding plate, thus reducing the equipment's maintenance workload and costs.

[0035] Please see Figure 1-7 If shale raw materials become damp during storage, they may stick together when entering the batching device hopper, causing poor material flow. Material accumulation in the pipes can also cause blockages, affecting the normal transport of materials. This indicates that the moisture content and fine powder content of the material are important factors leading to blockages in the batching device, and blockages can affect the smooth operation of the entire batching process. Based on this, this application provides a quantitative batching device for shale ceramsite raw materials, including a collection and dispensing component 1 for quantitative distribution and a dispensing component 2 disposed on the collection and dispensing component 1.

[0036] The collection and dispensing component 1 includes a base 11, on which a collection frame 12 is provided, and the collection frame 12 is located below the dispensing component 2;

[0037] The distribution component 2 includes a material guiding component 21. The bottom of the material guiding component 21 maintains a fixed distance from the collection port of the collection frame 12. A sliding closing component 27 is provided on the top of the material guiding component 21. A distribution cylinder 23 is provided on the top of the sliding closing component 27. An inner cavity 210 is provided on the inner side of the distribution cylinder 23. A push plate 28 is provided on the inner side of the inner cavity 210 for quantitative distribution of materials.

[0038] The bottom of the base 11 is equipped with height-adjustable anchor bolts, which facilitates the adjustment of the device's level in different ground environments and ensures the accuracy of the batching process.

[0039] The collection frame 12 is installed on the base 11, directly below the distribution component 2. It has an inclined bottom plate inside to facilitate the material to slide towards the discharge port. The discharge port of the collection frame 12 is equipped with an adjustable gate. The opening and closing of the gate is controlled by an electric push rod to facilitate the control of the material discharge speed and flow rate.

[0040] The bottom of the material guiding assembly 21 maintains a fixed distance from the collection port of the collection frame 12, which can be adjusted according to actual production needs. The material guiding assembly 21 adopts a funnel-shaped structure and is made of smooth stainless steel plate to reduce material adhesion during the guiding process. Its top is tightly connected to the sliding sealing assembly 27 to ensure that the material can flow smoothly from the sliding sealing assembly 27 into the material guiding assembly 21.

[0041] The sliding sealing assembly 27 is located on top of the material guiding assembly 21 and mainly consists of a sliding plate and a drive unit. The sliding plate is made of wear-resistant engineering plastic with a polished surface to reduce friction with the material. The drive unit can be a cylinder or an electric actuator. The movement of the drive unit is controlled by a controller to slide the sliding plate, thereby controlling the feeding and sealing of the material.

[0042] The distribution cylinder 23 is installed on top of the sliding closed assembly 27. The distribution cylinder 23 on its inner side is the key part for realizing quantitative distribution. The inner wall of the distribution cylinder 23 is smooth to prevent material residue. A push plate 28 is provided inside the distribution cylinder 23. The push plate 28 fits tightly with the inner wall of the distribution cylinder 23. The push plate 28 is connected to the motor through a screw drive mechanism. The speed and rotation angle of the motor can be precisely controlled by the controller, thereby realizing the precise movement of the push plate 28 in the distribution cylinder 23 to quantitatively distribute the material.

[0043] Work process

[0044] First, shale ceramsite raw material is added into the distribution cylinder 23 through the feed inlet. Then, the controller controls the motor to drive the pusher plate 28 to move within the distribution cylinder 23, pushing the material to the sliding closing component 27 according to the preset batching amount. Next, the controller controls the drive device to slide the slide plate, opening the feed channel, and the material falls into the collection frame 12 through the guide component 21. When the material reaches the set amount, the controller controls the drive device to slide the slide plate to close the feed channel, completing one quantitative batching operation. Finally, the batched material is conveyed to the next process by controlling the gate at the discharge port of the collection frame 12.

[0045] By precisely controlling the movement of the pusher plate 28 within the distribution cylinder 23, the raw materials for shale ceramsite can be accurately quantitatively distributed, ensuring the accuracy of each batch and thus improving the quality stability of the shale ceramsite product.

[0046] The feeding component 21 has a funnel-shaped structure and a smooth surface. The sliding plate surface of the sliding sealing component 27 is polished, which reduces the adhesion of materials and effectively avoids the problem of material blockage affecting the batching process, thereby improving production efficiency.

[0047] The gate at the discharge port of the collection frame 12 has an adjustable opening, and the moving distance and speed of the push plate 28 can be precisely adjusted by the controller. It can flexibly control the amount of feed and the discharge speed according to different production needs, and adapt to diverse production requirements.

[0048] The inner side of the distribution cylinder 23 is provided with an inner cavity 210. The top of the inner cavity 210 is provided with a feed port and the bottom is provided with a discharge port. The discharge port is adapted to the sliding sealing component 27.

[0049] The top of the feed inlet of the inner cavity 210 is provided with a feeding port 24, a drive motor 25 is provided on one side of the feeding port 24, and a sealing cover is installed on the inner side of the feeding port 24. The sealing cover is opened and closed by the drive motor 25.

[0050] One or more through holes extending into the inner cavity 210 are provided on one side of the distribution cylinder 23. A telescopic component 22 is provided at the through hole. A push plate 28 is installed at one end of the telescopic component 22 located in the inner cavity 210. The push plate 28 slides against the inner wall of the inner cavity 210.

[0051] A fixed frame and a telescopic component 26 are provided on one side of the sliding sealing component 27. The telescopic component 26 is located on one side of the fixed frame, and a sliding plate 29 adapted to the discharge port is fixed to the piston rod end of the telescopic component 26.

[0052] The outer side of the sliding plate 29 is provided with an outer frame 291, and the inner side of the outer frame 291 is provided with a cleaning area 292 for cleaning the surface of the sliding plate 29.

[0053] The inner cavity 210 inside the distribution cylinder 23 is the area for temporary storage and quantitative distribution of materials. The inlet at the top of the inner cavity 210 facilitates the entry of materials into the inner cavity 210, while the outlet is adapted to the sliding sealing component 27 to ensure that materials can be conveyed out of the inner cavity 210 in an orderly manner. The inlet has a large diameter and can be set in a funnel shape to accelerate the material flow rate. The size of the outlet is precisely designed according to the flow rate required for production.

[0054] The feeding port 24 is located at the top of the feed inlet of the inner cavity 210, facilitating the feeding of shale ceramsite raw materials into the inner cavity 210. The drive motor 25 on one side of the feeding port 24 is a servo motor, which can precisely control the opening and closing angle and time of the closed cover. When feeding, after receiving a signal from the control system, the drive motor 25 drives the closed cover to open, and the material enters the inner cavity 210 through the feeding port 24. After feeding is completed, the drive motor 25 drives the closed cover to close, preventing material leakage and the entry of external impurities.

[0055] The through hole on one side of the distribution cylinder 23 provides a passage for the installation and operation of the telescopic component 22. The telescopic component 22 can be an electric push rod, which has precise operation and high stability. The stroke and speed of the electric push rod can be precisely adjusted by the control system. The push plate 28 fits tightly against the inner wall of the inner cavity 210 and can slide. The surface of the push plate 28 is also smoothed, and the material is high-strength plastic or alloy to reduce weight and ensure wear resistance. When quantitative distribution is required, the telescopic component 22 pushes the push plate 28 to move in the inner cavity 210, pushing a certain amount of material to the discharge port.

[0056] The fixed frame on one side of the sliding closure assembly 27 provides a stable installation base for the telescopic component 26. The telescopic component 26 also uses an electric push rod, and the sliding plate 29 fixed at the end of its piston rod is adapted to the discharge port. The sliding plate 29 can accurately open or close the discharge port under the drive of the telescopic component 26. When the material reaches the discharge port, the telescopic component 26 pushes the sliding plate 29 to open the discharge port, and the material falls into the collection frame 12 through the guide assembly 21. After the material is conveyed, the telescopic component 26 pulls the sliding plate 29 to close the discharge port to prevent the material from continuing to flow out.

[0057] The outer frame 291 of the sliding plate 29 serves to protect and support the cleaning area 292. The cleaning area 292 can be configured as a sponge or brush structure and is equipped with a spray device to periodically spray cleaning liquid onto the surface of the sliding plate 29. When the sliding plate 29 passes through the cleaning area 292 during its extension and retraction, the sponge or brush wipes the surface of the sliding plate 29 to remove adhering materials, keeping the surface of the sliding plate 29 clean and ensuring its sealing performance with the outlet.

[0058] Workflow

[0059] First, the drive motor 25 controls the opening of the sealing cover, and the shale ceramsite raw material enters the inner cavity 210 through the feeding port 24. Then, the control system controls the telescopic component 22 to push the push plate 28 within the inner cavity 210 according to the preset batching amount, pushing the corresponding amount of material towards the discharge port. Next, the telescopic component 3 26 pushes the sliding plate 29 to open the discharge port, and the material falls into the collection frame 12 through the discharge port and the guide component 21. During the extension and retraction of the sliding plate 29, the cleaning area 292 on the inner side of the outer frame 291 cleans the surface of the sliding plate 29. Finally, after completing one batching operation, all components reset, awaiting the next batching command.

[0060] By precisely controlling the movement of the pusher plate 28 through the telescopic component 22, the precise quantitative distribution of shale ceramsite raw materials can be achieved, ensuring the accuracy of each batch of materials and thus improving the stability of shale ceramsite product quality.

[0061] The closed cover controlled by the drive motor 25 and the sliding plate 29 driven by the telescopic component 26 respectively realize precise control of feeding and discharging, avoid material leakage and waste, and improve production efficiency.

[0062] The cleaning area 292 on the outer side of the sliding plate 29 can clean the surface of the sliding plate 29 during operation, preventing material adhesion from affecting the sealing performance of the outlet and the normal operation of the sliding plate 29, thus reducing the maintenance workload and cost of the equipment.

[0063] The fixed frame provides stable support for the telescopic component 26, ensuring the accurate and reliable operation of the sliding plate 29; the reasonable design and material selection of the inner cavity 210, push plate 28 and other structures ensure the stability and durability of the entire distribution assembly 2.

[0064] The push plate 28 includes a plate body 281. Two symmetrically arranged positioning holes 283 are provided on one side contact surface 282 of the plate body 281. A guide rod for limiting is installed at the positioning hole 283. An installation hole 284 is provided in the middle of the plate body 281 between the two positioning holes 283. The installation hole 284 is adapted to one end of the telescopic component 22.

[0065] A telescopic component 13 is provided on one side of the collection frame 12. The telescopic component 13 is used to push the collection frame 12 to reciprocate linearly along the base 11.

[0066] The shape of the push plate 28 body 281 is designed to be rectangular, and its surface is polished to reduce the friction between it and the inner wall of the inner cavity 210, so as to ensure that the push plate 28 can slide smoothly in the inner cavity 210.

[0067] Two symmetrical positioning holes 283 are located on one side of the contact surface 282 of the plate 281. One end of the guide rod is tightly installed in the positioning hole 283, and the other end is engaged with the corresponding guide groove on the inner cavity 210 wall. The width of the guide groove is slightly larger than the diameter of the guide rod to ensure that the guide rod can slide freely in the groove, and at the same time, it plays a role in accurately guiding the movement direction of the push plate 28 and preventing the push plate 28 from deviating during movement.

[0068] The mounting hole 284 is located in the middle of the plate 281 between the two positioning holes 283. During installation, the end of the telescopic component 22 is inserted into the mounting hole 284 and fixed with bolts or pins to ensure a firm connection. During the extension and retraction of the telescopic component 22, it can stably drive the push plate 28 to move in the inner cavity 210.

[0069] Working process of push plate 28: When telescopic component 22 is activated, its end drives push plate 28 to move in inner cavity 210 through mounting hole 284. As the guide rod slides in the guide groove, push plate 28 always moves along a predetermined straight line, accurately pushing the shale ceramsite raw material in inner cavity 210 towards the discharge port, realizing the function of quantitative distribution.

[0070] The telescopic component 13 on one side of the collection frame 12 is an electric push rod, which has the advantages of large thrust and precise stroke control. The rated thrust of the electric push rod is reasonably selected according to the weight of the collection frame 12 and the resistance during operation to ensure that the collection frame 12 can be smoothly pushed to reciprocate linearly along the base 11.

[0071] One end of the telescopic component 13 is fixed to one side of the collection frame 12 by welding or bolting, and the other end is mounted on a fixed bracket on the base 11. The fixed bracket is made of steel and has sufficient strength and stability to withstand the thrust of the telescopic component 13.

[0072] During the batching process, after the material falls from the discharge port into the collection frame 12, the control system activates the telescopic component 13 according to a preset program. The piston rod of the telescopic component 13 extends or retracts, pushing the collection frame 12 to reciprocate linearly along the guide rail on the base 11. The guide rail is a linear guide rail with a hardened surface to reduce frictional resistance and improve the smoothness and accuracy of the collection frame 12's movement. The reciprocating motion of the collection frame 12 ensures that the material is evenly distributed within the collection frame 12, preventing material accumulation in one place and facilitating subsequent collection and processing of the material.

[0073] The design of the positioning hole 283 and guide rod on the push plate 28 can accurately guide the movement direction of the push plate 28 and prevent the push plate 28 from deviating during movement, thereby ensuring the accuracy of the amount of material pushed each time, improving the accuracy of the quantitative distribution of shale ceramsite raw materials, and helping to ensure the stability of product quality.

[0074] The plate 281 and the telescopic component 22 are tightly fitted through the mounting hole 284, and the guide rod and guide groove cooperate to make the push plate 28 more stable during operation, reducing the probability of failure caused by vibration or shaking, and extending the service life of the push plate 28 and the entire device.

[0075] The telescopic component 13 pushes the collection frame 12 in a reciprocating linear motion, which can make the material falling into the collection frame 12 evenly distributed, avoid the accumulation of material, and facilitate further processing of the material, such as conveying and mixing.

[0076] The reciprocating motion of the collection box 12 enables automatic and uniform distribution of materials, reduces manual intervention, improves the automation level and production efficiency of the production process, and reduces production costs.

[0077] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
