Description
Technical Field
[0001] This utility model relates to the technical field of cement mixing devices, specifically, to a mixing device for cement production. Background Technology
[0002] In the cement production process, mixing is a crucial step. Its purpose is to fully and evenly mix cement raw materials (such as limestone, clay, iron powder, etc.) with additives to ensure the stable quality of cement products. When performing cement mixing operations, corresponding mixing devices are usually used.
[0003] Utility model patent CN222309269U discloses a mixing device for cement production, relating to the technical field of cement production mixing devices. It includes a housing with a feed hopper fixedly installed on its side wall and an installation hole on its upper wall. A drive box is fixedly installed within the installation hole. Material is introduced into the housing through the feed hopper. When the motor is started, the driven gear meshes with the driven gear, causing the driven gear to rotate the central rod. The central rod then rotates the turntable, causing the rotating rod to revolve around the central rod. The rotating rod indirectly drives the mixing rod to revolve and mix the material. Since the drive gear at the upper end of the rotating rod meshes with a gear ring, the rotating rod rotates on its own axis while revolving, mixing the material. The material is uniformly mixed through the rotation and revolution of the mixing rod, improving the efficiency of cement mixing and the yield of finished cement products.
[0004] While this technical solution offers advantages in improving cement mixing efficiency and cement production yield, most mixing devices typically use a discharge pipe directly installed from the bottom of the tank, with a discharge valve at the pipe for unloading. Due to the special nature of cement, various particles inside the cement can cause wear and tear on the discharge valve and its internal valve core when using a traditional discharge valve. This wear can affect the normal closure of the discharge valve, leading to damage. Furthermore, using a discharge valve can easily result in impurities getting stuck in the valve core, affecting its normal rotation and negatively impacting unloading. Therefore, we propose a mixing device for cement production. Utility Model Content
[0005] The purpose of this invention is to provide a mixing device for cement production to solve the defects mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0008] Preferably, the bottom slope is inclined downward at 45° to 60°, and the top surface of the sealing block has the same inclination angle as the bottom slope.
[0009] Preferably, the plane containing the inner wall of the conical cylinder is inclined downward at 45° to 60°, the upper conical chamber is in the shape of an inverted frustum, and the inclination angle of the unloading hopper is the same as the inclination angle of the bottom inclined surface.
[0010] The above two settings make unloading smoother.

[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] 1. This utility model uses a specially structured unloading assembly. A cylinder drives the unloading hopper and the sealing plug to move, replacing the traditional unloading valve. The sealing plug fits against the inclined surface at the bottom of the unloading cylinder. During unloading, the cylinder contracts, causing the sealing plug to move downward and open the unloading channel. Cement particles will not cause wear during the unloading process, avoiding the problem of poor valve closure due to wear. At the same time, the valve core-free structure design eliminates the possibility of impurities getting stuck and affecting unloading, ensuring smooth and stable unloading operation.
[0021] 2. This utility model sets the upper conical chamber of the conical cylinder and the unloading cylinder at a specific inclination angle, and the inclination angle of the sealing block and the unloading hopper is matched with the inclination angle of the bottom slope of the unloading cylinder, so that the cement material can slide down the inclined surface more smoothly under the action of gravity, reduce the accumulation and blockage of materials at the unloading part, speed up the unloading speed, improve the unloading efficiency, and ensure the efficient operation of the unloading link in the cement production process.

This utility model enables the addition of water and raw materials by installing a screw feeder and a water inlet pipe at the top of the mixing tank; combined with the mixing components at the top of the mixing tank, the mixing motor drives the mixing shaft and mixing blades to rotate, so as to fully mix the materials. From the addition of raw materials to the mixing process, a complete and efficient production process is formed, which ensures the stability of cement production quality and improves the overall production efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1-3 This utility model provides a technical solution: a mixing device for cement production, including a mixing tank 1, a conical cylinder 10 fixedly installed at the bottom of the mixing tank 1, a discharge pipe 11 fixedly installed at the bottom end of the conical cylinder 10, a discharge cylinder 12 fixedly installed on the wall of the discharge pipe 11, a bottom inclined surface 121 provided on the bottom surface of the discharge cylinder 12, an upper conical chamber 13 and a lower vertical chamber 14 arranged sequentially from top to bottom inside the discharge cylinder 12, the upper conical chamber 13 being connected to the conical cylinder 10, and a discharge assembly 3 provided at the bottom of the discharge pipe 11. The unloading assembly 3 includes a cylinder 31 located below the unloading pipe 11. The end of the telescopic shaft of the cylinder 31 is detachably connected to the unloading hopper 32. A sealing plug 33 is fixedly installed at the center of the bottom wall of the unloading hopper 32. The sealing plug 33 is located inside the unloading pipe 11 and is slidably connected to the unloading pipe 11. The top surface of the sealing plug 33 abuts against the bottom inclined surface 121. Driven by the cylinder 31, the unloading is opened and closed. Compared with the traditional unloading valve, the wear of cement particles on the components is reduced, the unloading valve is prevented from being damaged, and the unloading is guaranteed to proceed normally.
[0032] like Figure 2As shown, the bottom inclined surface 121 is set at a downward slope of 45° to 60°. The top surface of the sealing plug 33 has the same inclination angle as the bottom inclined surface 121. The plane containing the inner wall of the conical cylinder 10 is set at a downward slope of 45° to 60°. The upper conical chamber 13 is shaped like an inverted frustum. The inclination angle of the discharge hopper 32 is the same as that of the bottom inclined surface 121. This allows the cement material to slide quickly and smoothly along each inclined surface under the action of gravity, greatly reducing the possibility of material accumulation and blockage at the discharge point, and effectively improving the efficiency and smoothness of discharge.
[0033] like Figure 1 and Figure 2 As shown, the unloading assembly 3 also includes a base 30 located below the unloading pipe 11. The cylinder 31 is fixedly installed on the base 30 to provide a stable support foundation for the unloading assembly 3, ensuring the stability of the operation of each component during the unloading process and avoiding unloading abnormalities due to unstable support.
[0034] In this embodiment, a fixed support 311 is fixedly installed at the end of the telescopic shaft of the cylinder 31. The unloading hopper 32 is fixedly installed on the top surface of the fixed support 311 by multiple fastening bolts, so as to realize the stable connection between the unloading hopper 32 and the cylinder 31, and ensure that the telescopic movement of the cylinder 31 can reliably drive the unloading hopper 32 and the sealing plug 33 to move and complete the unloading operation.
[0035] like Figure 2 As shown, a guide sleeve 35 is fixedly installed on the base 30, and a guide post 34 is fixedly installed on the bottom surface of the unloading hopper 32. The guide sleeve 35 is fitted on the guide post 34 and slidably connected to the guide post 34, providing guidance and limiting for the up and down movement of the unloading hopper 32, effectively reducing the shaking and deviation of the unloading hopper 32 during the movement, making its movement more stable and precise, and ensuring the reliability of the unloading operation.
[0036] like Figure 1 As shown, a water inlet pipe 16 is fixedly installed on the top of the mixing tank 1, and a screw feeder 17 is provided on the top of the mixing tank 1. The discharge pipe 171 of the screw feeder 17 extends into the mixing tank 1, and water can be added using the water inlet pipe 16 and raw materials can be conveyed using the screw feeder 17.
[0037] like Figure 1As shown, a top cover 15 is fixedly installed on the top of the mixing tank 1. A mixing assembly 2 is provided on the top cover 15. The mixing assembly 2 includes a mixing motor 20 fixedly installed at the center of the top surface of the top cover 15. A mixing shaft 21 is fixedly installed at the end of the output shaft of the mixing motor 20. A mixing blade 22 is fixedly installed on the mixing shaft 21. The mixing blade 22 is located inside the mixing tank 1. The mixing motor 20 drives the mixing shaft 21 and the mixing blade 22 to rotate, so as to fully mix the cement raw materials and water in the mixing tank 1, so that the materials are evenly distributed, ensuring the stability of cement product quality and providing reliable mixing guarantee for cement production.
[0038] Finally, it should be noted that the cylinder 31, screw feeder 17, and stirring motor 20 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.
[0039] When using the cement production mixing device of this utility model, the cement raw materials are first transported into the mixing tank 1 through the discharge pipe 171 of the screw feeder 17, and an appropriate amount of water is added through the water inlet pipe 16. Then, the mixing motor 20 on the top cover 15 is started. The mixing motor 20 drives the mixing shaft 21 and the mixing blades 22 to rotate, and the raw materials and water in the tank are fully mixed until the materials are evenly distributed.
[0040] After mixing is completed, the cylinder 31 in the unloading assembly 3 is started. The telescopic shaft of the cylinder 31 drives the fixed support 311, the unloading hopper 32 and the sealing plug 33 to move downward. Since the top surface of the sealing plug 33 is in contact with the bottom inclined surface 121 of the unloading cylinder 12, as the sealing plug 33 moves downward, the unloading channel is opened. Under the guidance of the conical cylinder 10 and the conical chamber 13 on the unloading cylinder 12, the cement material in the mixing tank 1 is discharged quickly and smoothly through the unloading pipe 11 along each inclined surface under the action of gravity. The discharged material can be further discharged outward along the unloading hopper 32.
[0041] After unloading is completed, the sealing plug 33 and the unloading pipe 11 are cleaned. Then, the cylinder 31 is started to extend its telescopic shaft, which drives the sealing plug 33 to move upward and re-fit against the bottom inclined surface 121, closing the unloading channel and completing one mixing and unloading process.
[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
