Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically to a high-efficiency anti-clogging cement batching and dispensing device. Background Technology

[0002] Cement batching is a crucial step in cement production. Its core involves mixing raw materials such as limestone, clay, iron ore powder, and sandstone in specific proportions according to the cement type, strength grade, and other requirements. This ensures the quality of the clinker produced after calcination meets standards, ultimately leading to the production of compliant cement products. The main raw materials for cement batching include calcareous, siliceous, aluminous, and ferrous materials. The first step in cement batching is mixing these materials in a mixing tank. Therefore, the materials need to be added separately to the mixing tank. The current method involves weighing and metering the different materials before adding them to the mixing tank through the feed hopper.

[0003] CN220661310U discloses a high-efficiency concrete batching device. It includes a mixing drum and an end cap located at the top of the mixing drum. Two discharge pipes are symmetrically slidably arranged through the center of the end cap. A mounting shell is fixedly installed at the top center of the end cap. A proportioning cylinder is fixedly installed on both sides of the upper end of the mounting shell. Piston plates are fitted onto the upper ends of the two discharge pipes. Sealing rings that mate with the inner walls of the proportioning cylinders are fitted onto the outer sides of the two piston plates. A rotating plate, which is I-shaped, is rotatably mounted on one side of the mounting shell. Constraint rods that mate with the ends of the rotating plate are fixedly installed on the outer surfaces of the two discharge pipes. A drive assembly for driving the rotating plate to deflect is located inside the mounting shell. The beneficial effects of this invention are: through the interaction of the rotating plate and the constraint rods, the deflection of the rotating plate synchronously drives the discharge pipes to move up and down, achieving the effect of adjusting the storage capacity of the two proportioning cylinders, so that the storage capacity of the two proportioning cylinders is in a specified ratio, making proportion adjustment more convenient.

[0004] While the existing technology CN220661310U has many advantages in use, it still has the following problems: its cleaning of the feed hopper is not perfect. When the material enters the mixing tank through the feed hopper, it may become damp and clump together, causing blockage inside the feed hopper and affecting the smoothness of material discharge. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides an efficient anti-clogging cement batching and dispensing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a high-efficiency anti-clogging cement batching and dispensing device, including a mixing tank, a sealing cover, and a support column. The upper outer wall of the mixing tank is screwed to a cover plate. A feeding hopper is provided on one side of the upper outer wall of the cover plate. A rectangular corrugated pipe is welded to the lower outer wall of the feeding hopper. The sealing cover is screwed to the outer wall of the feeding hopper. A bearing seat is screwed to the sealing cover and the outer wall of the feeding hopper. A rotating shaft is interference-fitted inside the bearing seat. A circular array of material distribution plates is welded to the outer wall of the rotating shaft. The rotating shaft passes through both ends of the bearing seat and is screwed to the support column. A circular array of clamping sleeves is welded to the outer wall of the support column. A connecting shaft is provided inside the clamping sleeve. An extension rod is pinned to the outer wall of the connecting shaft. An impact hammer is welded to the end of the extension rod.

[0007] By adopting the above technical solution, when the material falls inside the feed hopper, its own weight and gravity press against the equalization plate, causing the equalization plate to rotate circumferentially via the rotating shaft. This allows the material to fall evenly, preventing dust from being generated by concentrated material falling. The equalization plate also shields the inside of the feed hopper, preventing material from being stirred up and wasting. As the rotating shaft rotates, the support column and extension rod rotate synchronously, allowing the impact hammer to periodically collide with the impact rod. The vibration generated by the impact is transmitted to the sealing cover and the feed hopper, providing vibrational conveying of the material. This reduces material adhesion and accumulation at the feed hopper or equalization plate. By reducing material residue, the accuracy of material feeding is improved, and the accumulation and clumping of residual material are prevented, ensuring the relative cleanliness of the feed hopper's inner wall. This achieves the purpose of preventing clogging in the feed hopper and ensuring smooth material falling.

[0008] Specifically, a connecting seat is welded to the lower end of the rectangular corrugated pipe, and the connecting seat is screwed to the feed inlet at the upper end of the cover plate. A guide plate is welded to the lower end of the inner wall of the feed hopper, and the guide plate is located inside the rectangular corrugated pipe, with the lower end of the guide plate located inside the connecting seat.

[0009] By adopting the above technical solution, the guide plate on the inner wall of the feed hopper extends into the rectangular corrugated pipe and the connecting seat, which can guide the raw material to flow along a fixed path, avoid the raw material from stagnating and accumulating inside the rectangular corrugated pipe, and the flexible and extensible shape of the rectangular corrugated pipe itself provides a basis for the vibration of the feed hopper and can reduce the transmission of the amplitude of the feed hopper to the mixing tank, thus ensuring the stable operation of the mixing tank. The connecting seat is secured by screws to ensure that the feed hopper is stably positioned at the upper end of the cover plate, ensuring that the material inside the feed hopper can be guided as a whole through the guide plate and then enter the mixing tank through the feed inlet.

[0010] Specifically, impact rods are threadedly connected to the outer walls of both sides of the sealing cover, and reinforcing plates are welded to the outer walls of the impact rods, with the reinforcing plates in contact with the impact hammers.

[0011] By adopting the above technical solution, the impact rod is in direct contact with the impact hammer, and the impact force is concentrated and transmitted to the feed hopper and the equalization plate. The impact force is dispersed by the rectangular corrugated pipe, which ensures that the feed hopper and the equalization plate can vibrate synchronously. This enables the vibration and dispersion of materials on the outside of the feed hopper and the equalization plate, and ensures the smooth feeding of subsequent materials.

[0012] Specifically, both ends of the connecting shaft are engaged with retaining rings, which are located on the outside of the retaining sleeve.

[0013] By adopting the above technical solution, the retaining ring is secured to the outside of the sleeve, which can effectively prevent the connecting shaft from moving axially when rotating or under force, and ensure the stability of the movement trajectory of the extension rod and the impact hammer.

[0014] Specifically, torsion springs are provided at both ends of the connecting shaft, and the two ends of the torsion springs are respectively connected to the connecting shaft and the outer wall of the sleeve.

[0015] By adopting the above technical solution, the torsion springs at both ends of the connecting shaft provide elastic restoring force. When the impact hammer strikes the impact rod, the connecting shaft is subjected to force and rotates inside the sleeve, causing the torsion spring to twist and store energy. When the impact hammer passes the impact rod and completes the impact, the deformation potential energy of the torsion spring can drive the extension rod and the impact hammer to automatically reset, so that the impact action forms a periodic cycle.

[0016] Specifically, a sealing gasket is adhered and fixed to the side of the sealing cover facing the feed hopper, and the sealing gasket is in contact with the outer wall of the feed hopper.

[0017] By adopting the above technical solution, the sealing gasket between the sealing cover and the feed hopper fills the gap between the two connecting surfaces, which can effectively prevent dust leakage generated during cement batching.

[0018] The beneficial effects of this utility model are:

[0019] The high-efficiency anti-clogging cement batching and dispensing device of this utility model uses an impact hammer that periodically impacts an impact rod. The vibration generated by the impact is transmitted to the sealing cover and the feed hopper, which vibrates and conveys the material, reducing the adhesion and accumulation of material in the feed hopper or the equalization plate. By reducing the amount of material residue, the accuracy of material dispensing can be improved, and the accumulation and clumping of residual material can be avoided, ensuring the relative cleanliness of the inner wall of the feed hopper. This achieves the purpose of preventing blockage in the feed hopper and ensuring the smooth flow of material.

[0020] The high-efficiency anti-clogging cement batching and dispensing device of this utility model has a material distribution plate that rotates circumferentially through a rotating shaft, which can make the material evenly dispersed and fall, avoiding the dust caused by concentrated material falling. In addition, the material distribution plate can block the inside of the feed hopper, preventing the material inside the mixing tank from being blown up and avoiding material waste.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the high-efficiency anti-clogging cement batching and dispensing device of this utility model includes a mixing tank 1, a sealing cover 2, and a support column 3. A cover plate 11 is screwed to the upper outer wall of the mixing tank 1. A feed hopper 12 is provided on one side of the upper outer wall of the cover plate 11. A rectangular corrugated pipe 14 is welded to the lower outer wall of the feed hopper 12. A sealing cover 2 is screwed to the outer wall of the feed hopper 12. A bearing seat 22 is screwed to the sealing cover 2 and the outer wall of the feed hopper 12. A rotating shaft 23 is interference-fitted inside the bearing seat 22. A material distribution plate 24 with a circular array is welded to the outer wall of the rotating shaft 23. The rotating shaft 23 passes through the bearing seat 22 and is screwed to both ends of the support column 3. A retaining sleeve 31 with a circular array is welded to the outer wall of the support column 3. A connecting shaft 32 is provided inside the retaining sleeve 31. An extension rod 33 is pinned to the outer wall of the connecting shaft 32. An impact hammer 36 is welded to the end of the extension rod 33.

[0030] During use, when the material falls inside the feed hopper 12, its own weight and gravity press against the equalization plate 24, causing the equalization plate 24 to rotate circumferentially via the rotating shaft 23. This allows the material to fall evenly, preventing concentrated material falling and dust generation. The equalization plate 24 also shields the inside of the feed hopper 12, preventing material from being stirred up inside the mixing tank 1 and avoiding material waste. When the rotating shaft 23 rotates, it carries the support column 3 and extension rod 33 to rotate synchronously, allowing the impact hammer 36 to periodically collide with the impact rod 21. The vibration generated by the impact can be transmitted to the sealing cover 2 and the feed hopper 12, vibrating and conveying the material. This reduces the adhesion and accumulation of material at the feed hopper 12 or the equalization plate 24. By reducing the amount of material residue, the accuracy of material feeding can be improved, and the accumulation and clumping of residual material can be avoided, ensuring the relative cleanliness of the inner wall of the feed hopper 12. This achieves the purpose of preventing blockage in the feed hopper 12 and ensuring the smooth flow of material.

[0031] For example, to guide the material, such as... Figure 2 As shown, a connecting seat 15 is welded to the lower end of the rectangular corrugated pipe 14. The connecting seat 15 is screwed to the feed inlet at the upper end of the cover plate 11. A guide plate 13 is welded to the lower end of the inner wall of the feed hopper 12. The guide plate 13 is located inside the rectangular corrugated pipe 14, and the lower end of the guide plate 13 is located inside the connecting seat 15.

[0032] During use, the guide plate 13 on the inner wall of the feed hopper 12 extends into the rectangular corrugated pipe 14 and the connecting seat 15, which can guide the raw material to flow along a fixed path, avoid the raw material from stagnating and accumulating inside the rectangular corrugated pipe 14, and the flexible and extensible shape of the rectangular corrugated pipe 14 provides a basis for the vibration of the feed hopper 12 and can reduce the transmission of the amplitude of the feed hopper 12 to the mixing tank 1, thus ensuring the stable operation of the mixing tank 1. The connecting seat 15 ensures that the feed hopper 12 is stably positioned above the cover plate 11 by screws, ensuring that the material inside the feed hopper 12 can be guided as a whole through the guide plate 13 and enter the mixing tank through the feed port.

[0033] For material dispersion, for example, such as Figure 2 As shown, impact rods 21 are threadedly connected to the outer walls of both sides of the sealing cover 2. Reinforcing plates are welded to the outer walls of the impact rods 21, and the reinforcing plates are in contact with the impact hammer 36.

[0034] During use, the impact rod 21 is in direct contact with the impact hammer 36, concentrating the impact force to the feed hopper 12 and the equalizing plate 24. The impact force is dispersed by the rectangular corrugated pipe 14, ensuring that the feed hopper 12 and the equalizing plate 24 can vibrate synchronously. This enables the material outside the feed hopper 12 and the equalizing plate 24 to be dispersed by vibration, ensuring the smooth feeding of subsequent materials.

[0035] To limit the rotational position, for example, such as Figure 5 As shown, both ends of the connecting shaft 32 are secured with retaining rings 34, which are located outside the retaining sleeve 31.

[0036] During use, the retaining ring 34 is locked on the outside of the retaining sleeve 31, which can effectively prevent the connecting shaft 32 from moving axially when rotating or under force, and ensure the stability of the movement trajectory of the extension rod 33 and the impact hammer 36.

[0037] For torsional reset, exemplarily, such as Figure 5 As shown, torsion springs 35 are provided at both ends of the connecting shaft 32, and the two ends of the torsion springs 35 are connected to the outer wall of the connecting shaft 32 and the sleeve 31, respectively.

[0038] During use, the torsion springs 35 at both ends of the connecting shaft 32 provide elastic restoring force. When the impact hammer 36 strikes the impact rod 21, the connecting shaft 32 is subjected to force and rotates inside the sleeve 31, causing the torsion spring 35 to twist and store energy. When the impact hammer 36 passes over the impact rod 21 and completes the impact, the deformation potential energy of the torsion spring 35 can drive the extension rod 33 and the impact hammer 36 to automatically reset, so that the impact action forms a periodic cycle.

[0039] For sealing purposes, exemplarily, such as Figure 2 As shown, a sealing gasket is glued and fixed to the side of the sealing cover 2 facing the feed hopper 12, and the sealing gasket is in contact with the outer wall of the feed hopper 12.

[0040] During use, the sealing gasket between the sealing cover 2 and the feed hopper 12 fills the gap between the two connecting surfaces, effectively preventing dust leakage during cement batching.

[0041] When this utility model is in use, the cement batching material is fed from the top of the feeding hopper 12 and falls along the inner wall of the feeding hopper 12 under the action of gravity. The falling material presses the material distribution plate 24 due to its own weight and gravity, causing the material distribution plate 24 to rotate circumferentially through the rotating shaft 23 in the bearing seat 22. Then, the material is guided by the guide plate 13, so that the material enters the connecting seat 15 along a fixed path and finally falls into the mixing tank 1.

[0042] The rotating shaft 23 rotates synchronously under the drive of the material equalization plate 24. The support columns 3 connected at both ends of the shaft 23 rotate together with the rotating shaft 23. Then, through the sleeve 31 and the connecting shaft 32, the extension rod 33 and the impact hammer 36 are driven to make a circular motion. During the motion, the impact hammer 36 periodically contacts and impacts the reinforcing plates of the impact rod 21 on both sides of the sealing cover 2. The resulting vibration is transmitted to the feed hopper 12 through the sealing cover 2. The vibration generated by the impact is transmitted along the feed hopper 12 and the material equalization plate 24, causing the material attached to the inner wall of the feed hopper 12 or the material equalization plate 24 to fall off.

[0043] The torsion springs 35 at both ends of the connecting shaft 32 deform and store energy during impact. After the impact, the elastic restoring force drives the impact hammer 36 to reset, ensuring that the impact action continues to cycle.
