Technical Field
[0001] This utility model relates to the technical field of plastering gypsum treatment equipment, specifically to a plastering gypsum homogenization equipment. Background Technology
[0002] To improve residents' living standards, the country has vigorously carried out infrastructure construction in recent years, leading to a year-on-year increase in the demand for high-standard gypsum materials. Gypsum is now being used more and more widely. During the production of building gypsum powder, freshly calcined powder often contains a certain amount of over-burned Type III anhydrous gypsum and under-burned dihydrate gypsum. Type III anhydrous gypsum quickly transforms into hemihydrate gypsum under the influence of steam or water. If calcined building gypsum is applied directly, the Type III anhydrous gypsum will absorb water, causing the building to expand and crack, which is detrimental to building safety. Therefore, building gypsum needs to be aged and homogenized before use. Aging and homogenization can stabilize the phase composition and properties of the powder, and increase the proportion of beneficial phases, thereby improving the powder's processing and physical properties and enhancing product quality.
[0003] Currently, mechanical aging and homogenization of building gypsum is commonly used. This method often suffers from poor aging and homogenization effects and low aging and homogenization efficiency. To address this, we propose a plaster gypsum homogenization device. Utility Model Content
[0004] The purpose of this invention is to provide a plaster homogenization device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] This utility model provides a plaster homogenization device, including a tank. The top of the tank has a feed inlet and an exhaust outlet. A variable frequency impeller feeder is provided at the feed inlet. The side wall of the tank has a discharge outlet and a first air inlet pipe. The discharge outlet is located at the top of the side wall of the tank. The first air inlet pipe is located at the bottom of the side wall of the tank. The bottom of the tank has a second air inlet pipe and a third air inlet pipe. A guide pipe is detachably fixed in the inner cavity of the tank. The air inlet of the guide pipe is located directly above the second air inlet pipe.
[0007] Furthermore, a guide plate for guiding the plaster gypsum is fixedly provided on one side of the feed inlet. The guide plate is located in the inner cavity of the tank. One end of the guide plate is fixedly connected to the top of the tank, and the other end of the guide plate away from the top of the tank is not connected to the bottom of the inner cavity of the tank.
[0008] Furthermore, the guide tube is detachably fixed on the bracket, and the bracket is fixedly installed at the bottom of the inner cavity of the tank.
[0009] Furthermore, the bracket includes a lower support rod, an upper support rod, and a three-jaw chuck for fixing the guide tube. Both the lower support rod and the upper support rod have several mounting holes. The lower support rod and the upper support rod are connected by bolts. The three-jaw chuck is fixedly installed at the end of the upper support rod away from the lower support rod. The end of the lower support rod away from the upper support rod is fixedly connected to the bottom end of the inner cavity of the tank.
[0010] Furthermore, the three-jaw chuck includes a chuck body with a central hole for placing a guide tube. The chuck body has an internal cavity containing a disc gear. One side of the disc gear has a helical groove, and the other side has teeth. A bevel gear meshes with the toothed side of the disc gear. The bevel gears are evenly distributed circumferentially along the cylindrical surface of the chuck body, fixing the disc gear within the cavity of the chuck body. A guide groove is provided on the chuck body, and a slider is installed within the guide groove. A jaw is fixed on the slider, and the side of the slider away from the jaw has a thread that meshes with the helical groove.
[0011] Furthermore, one end of the bevel gear has a square hole for inserting a wrench.
[0012] Compared with the prior art, the present invention has the following technical effects:
[0013] In this invention, by setting a variable frequency impeller feeder, the proportion of gypsum with significant differences in strength or setting can be controlled, enabling the gypsum to achieve homogenization in a single mixing process. After the variable frequency impeller feeder delivers the gypsum into the inner cavity of the tank, the gypsum falls towards the bottom of the inner cavity. A first air inlet pipe sprays a humid, hot airflow, which fully contacts the gypsum powder, aging and homogenizing the gypsum. The gypsum powder slowly falls to the bottom of the tank. Through a guide pipe and a second air inlet pipe, the gypsum powder is fully mixed with the humid, hot airflow sprayed from the second air inlet pipe within the guide pipe. After rapidly rising, it forms a fountain area at the top of the tank. Then, the gypsum powder slowly descends to the bottom of the tank and seeps back into the second air inlet pipe area, re-entering the guide pipe, forming an internal circulation. In this way, the gypsum powder absorbs moisture and is fully mixed in a fluidized state, improving the aging and homogenization effect and efficiency of the gypsum powder. The lower and upper support rods can be adjusted via mounting holes and bolts to maintain the distance between the guide tube and the second air inlet pipe. Furthermore, the three-jaw chuck can also adjust the distance between the guide tube and the second air inlet pipe by clamping the guide tube at different positions. The three-jaw chuck can also clamp guide tubes of different diameters. By adjusting the distance between the guide tube and the second air inlet pipe and by using guide tubes of different diameters, the gas-solid ratio inside and outside the guide tube can be adjusted, as can the size of the fountain zone. This controls the degree of aging and homogenization and the speed of internal circulation, further improving the aging and homogenization effect and efficiency of gypsum powder. Overall, the homogenization equipment provided by this invention improves the aging and homogenization effect and efficiency of gypsum powder, resulting in good aging and homogenization performance and high efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0019] Please see Figures 1 to 3 This embodiment provides a plaster homogenization device, including a tank 1, which can be made of metal. The top of the tank 1 is provided with a feed inlet 2 and an exhaust outlet 10. The feed inlet 2 has a funnel-shaped structure and is mainly used to put plaster into the inner cavity of the tank 1. The exhaust outlet 10 is used to discharge the hot and humid airflow in the inner cavity of the tank 1.
[0020] Specifically, a variable frequency impeller feeder 3 is installed at the feed inlet 2. The variable frequency impeller feeder 3 can feed materials separately or simultaneously by controlling different impeller feeders through frequency conversion. According to actual needs, the proportion of gypsum with large differences in strength or setting can be precisely controlled so that the gypsum can be mixed and homogenized in one go.
[0021] Specifically, the tank 1 has a discharge port 11 and a first air inlet pipe 5 on its side wall. The discharge port 11 is located at the top of the side wall of the tank 1, and the first air inlet pipe 5 is located at the bottom of the side wall of the tank 1. The discharge port 11 is used to discharge the aged and homogenized gypsum, allowing it to enter subsequent processing. The first air inlet pipe 5 is used to deliver a humid and hot airflow into the inner cavity of the tank 1. The humid and hot airflow mixes thoroughly with the gypsum, aging and homogenizing it.
[0022] Specifically, a second air inlet pipe 8 is provided at the bottom of the tank body 1, which is used to deliver hot and humid airflow into the inner cavity of the tank body 1. In this embodiment, the guide pipe 7 is circular in shape. The guide pipe 7 is detachably fixed to the bottom of the inner cavity of the tank body 1 by a bracket 6, and the bracket 6 is fixedly set at the bottom of the inner cavity of the tank body 1. The guide pipe 7 is vertically arranged, and the air inlet of the guide pipe 7 is located directly above the second air inlet pipe 8. During operation, the gypsum powder slowly falls to the bottom of the tank body 1, seeps into the area below the guide pipe 7, and then enters the guide pipe 7 with the hot and humid airflow sprayed by the second air inlet pipe 8 and mixes thoroughly with the hot and humid airflow. After rising rapidly, it forms a fountain area at the top of the tank body 1. Then, the gypsum powder slowly falls to the bottom of the tank body 1 and seeps into the area of the second air inlet pipe 8 again and is sprayed into the guide pipe 7, thus forming an internal circulation. The gypsum powder absorbs moisture and mixes thoroughly in a fluidized state.
[0023] Specifically, a third air inlet pipe 9 is also provided at the bottom of the tank body 1. The third air inlet pipe 9 is used to supply gas into the tank body 1. After the gypsum powder has been aged and homogenized, the first air inlet pipe 5, the second air inlet pipe 8 and the exhaust port 10 are closed. The third air inlet pipe 9 supplies gas into the inner cavity of the tank body 1. The gypsum powder that has been aged and homogenized flows in a boiling state under the action of the gas blown in by the third air inlet pipe 9 and flows out to the discharge port 11 for further processing.
[0024] Specifically, a guide plate 4 is fixedly installed on one side of the feed inlet 2. The guide plate 4 is located inside the tank 1. One end of the guide plate 4 is fixedly connected to the top of the tank 1, and the other end of the guide plate 4 away from the top of the tank 1 is not connected to the bottom of the tank 1. The guide plate 4 is used to guide the gypsum powder fed by the variable frequency impeller feeder 3, preventing the gypsum powder from flowing directly to the discharge port 11, thereby allowing the gypsum powder to be fully mixed with the hot and humid airflow sprayed from the first air inlet pipe 5.
[0025] Specifically, the bracket 6 includes a lower support rod 61, an upper support rod 62, and a three-jaw chuck 64, which is used to fix the guide tube 7. Both the lower support rod 61 and the upper support rod 62 have several mounting holes 63. The upper support rod 62 and the lower support rod 61 are connected by bolts. During installation, the operator aligns the mounting holes 63 on the upper support rod 62 with the different mounting holes 63 on the lower support rod 61, and then fixes them with bolts. This allows for height adjustment of the lower support rod 61 and the upper support rod 62, thereby adjusting the distance between the guide tube 7 and the second air inlet pipe 8.
[0026] Specifically, a three-jaw chuck 64 is fixedly mounted at the end of the upper support rod 62 away from the lower support rod 61. The end of the lower support rod 61 away from the upper support rod 62 is fixedly connected to the bottom of the inner cavity of the tank body 1. The three-jaw chuck 64 is suitable for clamping guide tubes 7 in the shape of circles, equilateral triangles, or regular hexagons. When clamping a circular guide tube 7, the three-jaw chuck 64 can clamp guide tubes 7 of different diameters. The three-jaw chuck 64 includes a chuck body 641, with a central hole 650 for placing the guide tube 7. The chuck body 641 has an internal cavity containing a disc gear 642. One side of the disc gear 642 has a helical groove 643, and the other side has teeth. A bevel gear 644 meshes with the toothed side of the disc gear 642. The bevel gears 644 are evenly distributed circumferentially along the cylindrical surface of the chuck body 641, fixing the disc gear 642 within the cavity of the chuck body 641. A guide groove 649 is provided on the chuck body 641, within which a slider 646 is installed. A jaw 647 is connected to the slider 646 via a fastening bolt 648. The side of the slider 646 away from the jaw 647 (the contact surface between the slider 646 and the disc gear 642) has threads that mesh with the helical groove 643. A square hole 645 for inserting a wrench is provided at the outer end of the bevel gear 644.
[0027] Specifically, during operation, the operator inserts a wrench into the square hole 645 and then rotates the wrench. The bevel gear 644 also rotates, meshing with the toothed side of the disc gear 642. The bevel gear 644 drives the disc gear 642 to rotate. The spiral groove 643 on the other side of the disc gear 642 meshes with the thread on the slider 646. As the disc gear 642 rotates, the slider 646 moves radially in the guide groove 649 through the meshing of the thread and the spiral groove 643, thereby driving the pawl 647 to move, thus achieving the clamping and loosening of the pawl 647 on the guide tube 7.
[0028] Specifically, the three-jaw chuck 64 can adjust the distance between the guide tube 7 and the second air inlet tube 8 by clamping the guide tube 7 at different positions.
[0029] Specifically, the homogenization equipment provided by this utility model, by setting a variable frequency impeller feeder 3, can control the proportion of gypsum with significant differences in strength or setting, enabling the gypsum to achieve homogenization in one step. After the variable frequency impeller feeder 3 feeds the gypsum into the inner cavity of the tank 1, the gypsum powder falls to the bottom of the inner cavity of the tank 1. The first air inlet pipe 5 sprays a humid and hot airflow, which fully contacts the gypsum powder, aging and homogenizing the gypsum. The gypsum powder slowly falls to the bottom of the tank 1. Through the setting of the guide pipe 7 and the second air inlet pipe 8, the gypsum powder is fully mixed with the humid and hot airflow sprayed by the second air inlet pipe 8 in the guide pipe 7. After rising rapidly, it forms a fountain area at the top of the tank 1. Then, the gypsum powder slowly falls to the bottom of the tank 1 and seeps into the area of the second air inlet pipe 8 and re-enters the guide pipe 7, forming an internal circulation. In this way, the gypsum powder absorbs moisture and is fully mixed in a fluidized state, improving the aging and homogenization effect and efficiency of the gypsum powder. The lower support rod 61 and upper support rod 62 can adjust the distance between the guide tube 7 and the second air inlet pipe 8 through the mounting hole 63 and bolts. Furthermore, the three-jaw chuck 64 can also adjust the distance between the guide tube 7 and the second air inlet pipe 8 by clamping the guide tube 7 at different positions. The three-jaw chuck 64 can also clamp guide tubes 7 of different diameters. By adjusting the distance between the guide tube 7 and the second air inlet pipe 8 and by using guide tubes 7 of different diameters, the gas-solid ratio inside and outside the guide tube 7 can be adjusted, as can the size of the fountain zone, thereby controlling the degree of aging and homogenization and the speed of internal circulation, further improving the aging and homogenization effect and efficiency of gypsum powder. Overall, the homogenization equipment provided by this utility model improves the aging and homogenization effect and efficiency of gypsum powder, resulting in good aging and homogenization effect and high aging and homogenization efficiency.
[0030] Specifically, the working principle of this utility model is as follows: The worker puts powdered gypsum into the feed inlet 2. The variable frequency impeller feeder 3 precisely controls the proportion of gypsum with significant differences in strength or agglomeration, enabling the gypsum to be mixed and homogenized in one step. The gypsum powder fed by the variable frequency impeller feeder 3 falls to the bottom of the inner cavity of the tank 1. The guide plate 4 guides the gypsum powder, and the first air inlet pipe 5 sprays hot and humid airflow into the inner cavity of the tank 1. The hot and humid airflow comes into contact with and combines with the gypsum powder, aging and homogenizing it. The gypsum powder slowly falls to the bottom of the tank 1, seeps into the area below the guide pipe 7, and then enters the guide pipe 7 with the hot and humid airflow sprayed by the second air inlet pipe 8, where it is fully mixed. After rising rapidly, it forms a fountain area at the top of the tank 1. Then, the gypsum powder slowly descends to the bottom of the tank 1 and seeps back into the area of the second air inlet pipe 8. The new injection into the guide pipe 7 forms an internal circulation, allowing the gypsum powder to absorb moisture and mix thoroughly in a fluidized state, thereby improving the aging and homogenization effect and efficiency. The lower support rod 61 and the upper support rod 62 can adjust the distance between the guide pipe 7 and the second air inlet pipe 8 through the mounting hole 63 and bolts. In addition, the three-jaw chuck 64 can also adjust the distance between the guide pipe 7 and the second air inlet pipe 8 by clamping the guide pipe 7 at different positions. The three-jaw chuck 64 can also clamp guide pipes 7 of different diameters. By adjusting the distance between the guide pipe 7 and the second air inlet pipe 8 and by using guide pipes 7 of different diameters, the gas and solid ratio inside and outside the guide pipe 7 can be adjusted, as can the size of the fountain zone, thereby controlling the degree of aging and homogenization and the speed of the internal circulation, further improving the aging and homogenization effect and efficiency of the gypsum powder.
