Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically to a high-efficiency grinding aid addition device for cement production. Background Technology

[0002] Grinding aids are additives used in the production and preparation of cement. In my country, the main grinding aids used are chemical substances such as ethylene glycol. The application of grinding aids in actual production should not be underestimated. In particular, in developed countries, the use of both liquid and solid grinding aids is quite comprehensive. In the cement production process, appropriate additives are needed to inject them into the mixing hopper and mix them with the cement raw materials.

[0003] Existing high-efficiency grinding aid additive devices for cement production use a powder metering pump to accurately measure the grinding aid and then add it to the mixing hopper through a feeding pipe. In this method, the grinding aid can only enter the mixing hopper at a fixed angle, which prevents it from fully contacting and mixing with the cement raw materials. This increases the subsequent mixing time, resulting in poor addition effect and low performance. Therefore, there is an urgent need for a high-efficiency grinding aid additive device for cement production. Utility Model Content

[0004] (a) Technical problems to be solved The technical problem to be solved by this utility model is to provide a high-efficiency grinding aid addition device for cement production, based on the current state of the technology.

[0005] (II) Technical Solution This utility model is achieved through the following technical solution: This utility model proposes a high-efficiency grinding aid additive device for cement production, including an additive pipe, an L-shaped air pipe installed inside the additive pipe, a conical dispersion block connected to one end of the air pipe, air holes distributed circumferentially on the outer wall of the dispersion block, an air pump connected to one end of the air pipe, a filter screen installed on the air inlet of the air pump, a bearing plate fixed on one side wall of the additive pipe, a shock-absorbing cavity opened in the bearing plate, a shock-absorbing seat installed in the shock-absorbing cavity, a shock-absorbing pad provided at the bottom of the shock-absorbing seat, and a flexible tube installed on the air pipe.

[0006] Furthermore, the air tube passes through the addition tube, and the bottom end of the air tube is connected to the dispersion block by a thread.

[0007] Furthermore, the dispersion block has a hollow structure, and the pores are formed on the dispersion block.

[0008] Furthermore, the other end of the air tube is connected to the output port of the air pump via a thread, and the filter screen is fixed to the input port of the air pump by screws.

[0009] Furthermore, the support plate is welded onto the adding pipe, and a connecting flange is provided at one end of the adding pipe.

[0010] Furthermore, the damping cavity is formed on the bearing plate, and the damping pad is bonded to both the damping cavity and the damping seat.

[0011] Furthermore, the air pump is fixed to the shock absorber base by bolts, and the flexible tube is threaded onto the air pipe. Furthermore, a powder metering pump is also installed on the adding pipe, and the powder metering pump is positioned above the air pipe.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model has the following advantages: This invention designs a material distribution mechanism consisting of an air pump, air pipes, a dispersing block, and air holes. During the addition of grinding aid, the high-pressure gas generated by the air pump is sprayed out through the air pipes and air holes on the dispersing block, acting on the grinding aid flowing along the surface of the dispersing block. This allows the grinding aid to diffuse and be evenly distributed onto the cement raw materials by gravity. This method ensures the uniformity of contact between the grinding aid and the cement material, thereby shortening the subsequent mixing time and effectively improving the addition effect and functionality of the device.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] like Figures 1-3As shown in this embodiment, a high-efficiency grinding aid addition device for cement production includes an addition pipe 1 for guiding the grinding aid. An L-shaped air pipe 9 is installed inside the addition pipe 1. One end of the air pipe 9 is connected to a conical dispersion block 3, which can initially disperse the grinding aid. The outer wall of the dispersion block 3 has circumferentially distributed air holes 4. One end of the air pipe 9 is connected to an air pump 7, and the high-pressure gas generated acts on the grinding aid to further disperse it. A filter screen 8 is installed on the air inlet of the air pump 7 to filter the intake gas. A bearing plate 5 is fixed on one side wall of the addition pipe 1. A shock-absorbing cavity 11 is opened in the bearing plate 5. A shock-absorbing seat 6 is installed in the shock-absorbing cavity 11. A shock-absorbing pad 12 is provided at the bottom of the shock-absorbing seat 6. A flexible tube 10 is installed on the air pipe 9 to reduce the vibration of the air pump 7 during operation.

[0017] like Figures 1-3 In this embodiment, the air pipe 9 passes through the addition pipe 1, and the bottom end of the air pipe 9 is connected to the dispersion block 3 by a thread. The dispersion block 3 has a hollow structure, and air holes 4 are formed on the dispersion block 3. The other end of the air pipe 9 is connected to the output port of the air pump 7 by a thread. The filter screen 8 is fixed to the input port of the air pump 7 by screws. During the addition of the grinding aid, the high-pressure gas generated by the air pump 7 is sprayed out through the air pipe 9 and the air holes 4 on the dispersion block 33 and acts on the grinding aid flowing along the surface of the dispersion block 3, thereby causing it to diffuse and be evenly spread on the cement raw materials by gravity. This method can ensure the uniformity of contact between the grinding aid and the cement material, thereby shortening the subsequent mixing time and effectively improving the addition effect and functionality of the device.

[0018] like Figures 1-3 In this embodiment, the support plate 5 is welded to the adding pipe 1, and a connecting flange is reserved at one end of the adding pipe 1. The damping cavity 11 is formed on the support plate 5. The damping pad 12 is bonded to the damping cavity 11 and the damping seat 6. The air pump 7 is fixed to the damping seat 6 by bolts. The flexible tube 10 is installed on the air pipe 9 by threads. The adding pipe 1 is also equipped with a powder metering pump 2, which is located above the air pipe 9. During the operation of the air pump 7, the damping pad 12 and the flexible tube 10 combine to reduce the vibration of the air pump 7 on the adding pipe 1, ensuring its stable operation. The powder metering pump 2 can accurately measure the content of the added grinding aid.

[0019] The specific implementation process of this embodiment is as follows: First, the addition pipe 1 is installed and fixed and connected to an external power source. During use, the powder metering pump 2 accurately measures the content of the added grinding aid and adds it through the addition pipe 1. During the addition of the grinding aid, the high-pressure gas generated by the air pump 7 is sprayed out through the air pipe 9 and the air holes 4 on the dispersion block 33 and acts on the grinding aid flowing along the surface of the dispersion block 3, thereby spreading it and evenly spreading it on the cement raw material by gravity. This method can ensure the uniformity of contact between the grinding aid and the cement material, thereby shortening the subsequent mixing time and effectively improving the addition effect and functionality of the device. At the same time, during the operation of the air pump 7, the shock-absorbing pad 12 and the flexible pipe 10 are combined to reduce the vibration of the air pump 7 on the addition pipe 1, ensuring its stable operation.
