Description

Technical Field

[0001] This utility model relates to the technical field of column hopper mixers, specifically a column hopper mixer. Background Technology

[0002] A mixer is a mechanical device that uses mechanical force and gravity to uniformly mix two or more materials. During the mixing process, the contact surface area of ​​the materials can be increased to promote chemical reactions and accelerate physical changes.

[0003] The column-type hopper mixer is a category of mixers that can automatically perform functions such as lifting, mixing, and lowering. Existing column-type hopper mixers use a rotary mechanism to drive the hopper to rotate, and then use the rotating hopper to mix the materials. However, to improve mixing efficiency, a stirring rod is added to the hopper for stirring. This requires power to drive the stirring rod, which increases the weight of the entire hopper, thus increasing the load on the rotary mechanism and making it prone to wire entanglement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a column-type hopper mixer.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a column-type hopper mixer, comprising a mixer body consisting of a column, a lifting mechanism, a rotating mechanism, and a mixing hopper. The lifting mechanism is installed inside the column and is used to drive the rotating mechanism to move up and down along the column. The output end of the rotating mechanism is fixedly connected to the mixing hopper and is used to drive the mixing hopper to rotate.

[0007] The mixing hopper is equipped with a non-powered stirring mechanism for stirring the materials inside the mixing hopper. The non-powered stirring mechanism includes a crossbar arranged horizontally inside the mixing hopper and parallel to the output shaft of the rotary mechanism. A flexible chain is mounted on the crossbar and swings along the axial direction of the crossbar. The outer end of the flexible chain does not contact the inner wall of the mixing hopper when rotating.

[0008] As a preferred embodiment of this utility model, the connecting pipe has a flared connecting portion at one end that connects with the crossbar.

[0009] As a preferred embodiment of this utility model, the flexible chain is provided in multiple ways, and the lengths of adjacent flexible chains are such that they do not collide with each other.

[0010] As a preferred embodiment of this invention, the flexible chain is made of corrosion-resistant stainless steel.

[0011] As a preferred embodiment of this utility model, the crossbar is provided with a riveting block, and the fixed end of the flexible chain is fixed to the riveting block by a rivet.

[0012] As a preferred technical solution of this utility model, the mounting tube is provided with a limiting cavity that matches the crossbar, and the mounting tube is also provided with a through cavity that communicates with the limiting cavity and allows the flexible chain to pass through during installation.

[0013] The beneficial effects of this utility model are:

[0014] 1. This type of column-type hopper mixer consists of a column, a lifting mechanism, a rotating mechanism, and a mixing hopper as its main body. Inside the mixing hopper, there is a non-powered stirring mechanism that agitates the materials inside. The non-powered stirring mechanism consists of a crossbar and a flexible chain that swings along the axis of the crossbar. When the mixing hopper rotates, the crossbar rotates, and under the action of centrifugal force, it swings and unfolds along the axis of the crossbar to disperse the mixed materials, thereby improving the mixing efficiency. It does not require a separate power source for driving and has the characteristics of simple structure and light weight.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a column-type hopper mixer, which includes a mixer body composed of a column 1, a lifting mechanism 2, a rotating mechanism 3 and a mixing hopper 4. The lifting mechanism 2 is installed inside the column 1 and is used to drive the rotating mechanism 3 to move up and down along the column 1. The output end of the rotating mechanism 3 is fixedly connected to the mixing hopper 4 and is used to drive the mixing hopper 4 to rotate.

[0024] The innovation of this utility model lies in the fact that a non-powered stirring mechanism 5 is provided inside the mixing hopper 4 to stir the materials inside the hopper; the lifting mechanism 2 is equipped with a locking mechanism, which locks the rotating mechanism when it rises, and this locking is achieved by a hydraulic cylinder. The column 1, lifting mechanism 2, rotating mechanism 3, and mixing hopper 4 are all components of existing column-type hopper mixers, and their specific structures will not be described in detail here.

[0025] The non-powered stirring mechanism is the innovation of this utility model, and therefore will be described in detail. The non-powered stirring mechanism 5 includes a horizontal bar 6 arranged within the mixing hopper 4 and horizontally aligned with the output shaft of the rotating mechanism 3. A flexible chain 7 is mounted on the horizontal bar 6 and swings along its axial direction. The outer end of the flexible chain 7 does not contact the inner wall of the mixing hopper 4 during rotation. Inside the mixing hopper 4, a non-powered stirring mechanism 5 is provided to stir the materials inside. The non-powered stirring mechanism 5 consists of the horizontal bar 6 and the flexible chain 7 that swings along its axial direction. When the mixing hopper 4 rotates, the horizontal bar 6 rotates, thus swinging and unfolding along its axial direction under centrifugal force to disperse the mixed materials, thereby improving mixing efficiency. Furthermore, it requires no additional power source and is simple and lightweight.

[0026] The mixing hopper 4 has a horizontally arranged mounting pipe 8 on its side wall, which communicates with the inner cavity of the mixing hopper 4. The inner wall of the mixing hopper 4 also has a connecting pipe 9 that matches the position of the mounting pipe 8. One end of a crossbar 6 passes through the mounting pipe 8 and is inserted into the connecting pipe 9. A first flange 10 is located at the end of the crossbar 6, and a second flange 11 is located at the port of the connecting pipe 9. The first flange 10 and the second flange 11 are fixed together with bolts. The crossbar 6 and the mounting pipe 8 are connected via the first flange 10 and the second flange 11, which facilitates disassembly and cleaning of the interior of the mixing hopper 4. A rubber sealing layer is installed between the first flange 10 and the second flange 11 to ensure good overall sealing.

[0027] The connecting pipe 9 has a flared docking part 12 at one end that connects with the crossbar 6. This serves as a guide, making it easy for the end of the crossbar to be inserted into the docking part during installation. Under the guidance of the docking part, the crossbar is guided into the dock. In this way, the connecting pipe and the installation pipe support and limit the two ends of the crossbar, thus providing better installation temperature performance.

[0028] The flexible chain 7 is provided in multiple ways, and the length of adjacent flexible chains 7 is set to ensure that they do not collide with each other, thus avoiding collisions and entanglement between the flexible chains 7. The specific length setting is designed according to the working requirements.

[0029] The flexible chain 7 is made of corrosion-resistant stainless steel, which makes it wear-resistant.

[0030] The crossbar 6 is provided with a rivet block 13. The fixed end of the flexible chain 7 is fixed to the rivet block 13 by rivets. The fixed end of the flexible chain 7 is riveted to the crossbar, which has the advantage of good fixing effect. The rivet block is welded to the crossbar 6.

[0031] The installation tube 8 is provided with a limiting cavity 14 that matches the crossbar 6. The size of the limiting cavity 14 is consistent with the size of the crossbar, which serves to limit the crossbar and facilitates the insertion of the crossbar into the connecting tube during installation. The installation tube 8 is also provided with a through cavity 15 that communicates with the limiting cavity 14 and allows the flexible chain 7 to pass through during installation, thus enabling the crossbar with the flexible chain to be assembled and disassembled.

[0032] During operation, this column-type hopper mixer consists of a column 1, a lifting mechanism 2, a rotating mechanism 3, and a mixing hopper 4. The lifting mechanism 2 drives the rotating mechanism 3 to rise and fall along the column 1, and the output end of the rotating mechanism 3 is fixedly connected to the mixing hopper 4 to drive the mixing hopper 4 to rotate. This invention has a non-powered stirring mechanism 5 inside the mixing hopper 4 to stir the material inside the mixing hopper 4. The non-powered stirring mechanism 5 consists of a crossbar 6 and a flexible chain 7 that swings along the axis of the crossbar 6. When the mixing hopper 4 rotates, the crossbar 6 rotates, and under the action of centrifugal force, it swings and unfolds along the axis of the crossbar 6 to disperse the mixed material, thereby improving the mixing efficiency. It does not require a separate power source for driving and has the characteristics of simple structure and light weight.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
