Description

Technical Field

[0001] This utility model relates to the field of building and building materials technology, specifically to a gypsum slurry preparation device. Background Technology

[0002] In the construction, building materials, and related industries, hydrogen peroxide-foamed gypsum is widely used in wall construction and interior decoration due to its excellent properties such as lightweight, thermal insulation, and sound insulation. The quality of the gypsum slurry formulation directly determines the final performance of the hydrogen peroxide-foamed gypsum. Currently, the industry relies heavily on traditional mixing equipment for preparing gypsum slurry for hydrogen peroxide-foamed gypsum. However, these devices have numerous technical limitations in practical applications and struggle to meet the production demands for high-quality slurry.

[0003] First, traditional mixing equipment lacks precision in raw material delivery and proportioning. Existing equipment typically uses manual feeding or simple pipeline transportation, which cannot achieve precise quantitative control of gypsum powder, hydrogen peroxide, and various additives. Deviations in raw material proportions can easily lead to reduced foaming efficiency and uneven pore distribution in the slurry, thus affecting the strength and thermal insulation performance of hydrogen peroxide-foamed gypsum. At the same time, in some equipment, the feed pipe and the mixing tank cover are fixedly connected. When the tank cover is raised or lowered, the pipe is easily stretched, deformed, or broken, increasing equipment maintenance costs and the risk of production interruption.

[0004] Secondly, poor mixing uniformity is one of the core problems of traditional equipment. Existing equipment mostly adopts a single stirring blade structure, which can only perform radial stirring of the slurry and cannot effectively drive the raw materials at the bottom of the tank to participate in the mixing. This causes gypsum powder to easily settle and clump at the bottom of the tank, which not only affects the overall uniformity of the slurry, but may also block the discharge port. In addition, the low precision of the connection between the stirring shaft and the tank cover of some stirring devices makes it easy to shake during the stirring process, further aggravating the problem of uneven mixing and reducing the quality of slurry preparation.

[0005] Furthermore, the equipment lacks ease of operation and stability. Traditional mixing tanks are mostly fixed structures, requiring unloading via pipelines after slurry preparation, resulting in complex operation and potential slurry residue. Some movable mixing tanks lack precise positioning mechanisms, easily deviating from their preset positions during movement, causing the tank lid to fail to seal properly with the tank body, leading to slurry splashing or odor leakage. Additionally, the lifting and adjustment of the tank lid often relies on a single power component, making fine-tuning difficult, resulting in poor sealing and affecting the stability of the slurry reaction environment.

[0006] Therefore, it is necessary to study a gypsum slurry preparation device. Utility Model Content

It solves the problems of large deviation in raw material ratio, easy damage to the feed pipe, uneven mixing leading to gypsum powder clumping, inconvenient movement and inaccurate positioning of the preparation tank, and poor sealing effect of the tank lid in traditional devices.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a gypsum slurry preparation device, comprising a preparation box and a preparation tank. The preparation box has a placement groove on its front side, and the preparation tank is located inside the placement groove. The front side of the placement groove is hinged with a double door. A hydraulic cylinder is fixedly connected to the center of the top of the preparation box. The output end of the hydraulic cylinder passes through the preparation box and is fixedly connected to a tank cover adapted to the preparation tank. An installation groove is provided at the bottom of the output end of the hydraulic cylinder. An electric push rod is fixedly connected inside the installation groove and is fixedly connected to the tank cover. Four symmetrical solenoid valves are connected to the top of the tank cover. Telescopic pipes are connected to the input ends of the solenoid valves. The top of the telescopic pipes passes through the tank cover and is connected to a connecting flange. A connecting block is fixedly connected to the output end of the electric push rod. A rotary motor is installed inside the connecting block. A stirring shaft is fixedly connected to the output end of the rotary motor via a coupling. A stirring blade is fixedly connected to the bottom of the stirring shaft, and a spiral blade is fixedly connected to the surface of the stirring shaft.

[0010] As a preferred embodiment of this utility model, the inner walls of the preparation box are symmetrically and fixedly connected to both sides, and a cylinder is fixedly connected to the outer side of the preparation box. The output end of the cylinder passes through the connecting plate and is fixedly connected to a clamping plate, and the clamping plate is used in conjunction with the preparation tank.

[0011] As a preferred embodiment of this utility model, the connecting plate is symmetrically provided with limiting grooves on the side facing the preparation tank, and the back of the clamping plate is symmetrically fixedly connected with limiting posts, and the limiting posts are slidably connected to the limiting grooves.

[0012] As a preferred embodiment of this utility model, the bottom of the placement groove is symmetrically provided with movable grooves, and the four corners of the bottom of the preparation tank are fixedly connected with movable wheels, and the movable wheels are tactilely connected to the movable grooves.

[0013] As a preferred embodiment of this invention, a controller is hinged to the outside of the preparation box, and a human-machine interface is provided on the surface of the controller.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model utilizes a hydraulic cylinder fixedly connected to the center of the top of the mixing tank, an electric push rod fixedly connected to the bottom mounting groove of the hydraulic cylinder output end, and the coordinated operation of the tank lid. The hydraulic cylinder can drive the tank lid to achieve coarse adjustment and lifting, while the electric push rod can precisely fine adjust the position of the tank lid, solving the problems of low tank lid docking accuracy and easy material leakage in traditional devices. At the same time, the four symmetrical solenoid valves connected to the top of the tank lid, the telescopic pipe connected to the input end of the solenoid valves, and the connecting flange connected to the top of the telescopic pipe work together.

When the rotary motor drives the stirring shaft to rotate, the spiral blades can transport the raw materials at the bottom of the preparation tank upwards, while the stirring blades perform radial mixing of the raw materials, achieving all-round mixing without dead angles and effectively preventing gypsum powder from clumping.

This solves the problems of uneven mixing and inconvenient tank movement in traditional devices. Attached Figure Description

[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] like Figures 1 to 4As shown, this utility model provides a gypsum slurry preparation device, including a preparation box 1 and a preparation tank 2. The front of the preparation box 1 has a placement groove 3, which provides dedicated space for the preparation tank 2 and allows for initial positioning of the tank. The preparation tank 2 is located inside the placement groove 3 and is used to contain gypsum powder, hydrogen peroxide, and other additives to complete the slurry preparation reaction. The front of the placement groove 3 is hinged with a double door 4, which allows the placement groove 3 to open and close. When closed, it isolates external dust and impurities from entering the device, protecting the slurry preparation environment and providing a certain degree of noise reduction. When open, it facilitates the placement and removal of the preparation tank 2. A hydraulic cylinder 5 is fixedly connected to the center of the top of the preparation box 1. The hydraulic cylinder 5 is a container... The lifting and lowering of the lid 6 provides the main power. The output end of the hydraulic cylinder 5 passes through the mixing box 1 and is fixedly connected to the lid 6, which is adapted to the mixing tank 2. The lid 6 can seal and connect with the mixing tank 2 to prevent slurry splashing or odor leakage during the mixing process. The top of the lid 6 is symmetrically fixedly connected to guide columns, and the guide columns are slidably connected to the mixing box 1. The guide columns can limit the lifting and lowering trajectory of the lid 6 to prevent the lid 6 from deviating during movement and ensure that the lid 6 can accurately connect with the mixing tank 2. The bottom of the output end of the hydraulic cylinder 5 is provided with a mounting groove, which provides a stable mounting carrier for the electric push rod 7. The electric push rod 7 is fixedly connected inside the mounting groove and is fixedly connected to the lid 6. The electric push rod 7 can make fine adjustments to the position of the lid 6. To compensate for the insufficient lifting precision of hydraulic cylinder 5, the sealing fit between tank cover 6 and tank body 2 is further improved. Four symmetrical solenoid valves 8 are connected to the top of tank cover 6. These solenoid valves 8 can precisely control the on / off flow and volume of each raw material. A telescopic pipe 9 is connected to the input end of each solenoid valve 8. The telescopic pipe 9 is telescopic, adapting to the lifting and lowering movements of tank cover 6, preventing damage to the pipes due to the movement of tank cover 6. The top of the telescopic pipe 9 penetrates tank cover 6 and is connected to a connecting flange 10. The connecting flange 10 is connected to external feed pipes (the interiors of the four feed pipes are used to transport gypsum powder, hydrogen peroxide, and other related additives). The connecting flange 10 ensures a stable connection between the telescopic pipe 9 and the external feed pipes, preventing leakage during raw material transport. There is a leakage phenomenon; the output end of the electric push rod 7 is fixedly connected to the connecting block 11, which provides installation support for the rotary motor 12. The rotary motor 12 is installed inside the connecting block 11 and provides a power source for the stirring structure. The output end of the rotary motor 12 is fixedly connected to the stirring shaft 13 through a coupling. The stirring shaft 13 can transmit the power of the rotary motor 12 to the stirring component. The bottom of the stirring shaft 13 is fixedly connected to the stirring blade 14, which can radially stir the raw materials in the lower part of the preparation tank 2. The surface of the stirring shaft 13 is fixedly connected to the spiral blade 15, which can transport the raw materials at the bottom of the preparation tank 2 upward, and cooperate with the stirring blade 14 to form a three-dimensional stirring effect, avoiding the raw materials from clumping.

[0020] refer to Figure 3The inner wall of the preparation tank 2 is provided with a heating chamber 16, which provides space for heat transfer oil and spiral heating tube 17. The spiral heating tube 17 is fixedly connected inside the heating chamber 16. The spiral heating tube 17 can generate heat after being energized, and the spiral structure can increase the contact area with the heat transfer oil and improve the heating efficiency. The heating chamber 16 is filled with heat transfer oil, which can evenly transfer the heat generated by the spiral heating tube 17 to the inside of the preparation tank 2, avoiding local overheating or uneven heating of the slurry. A temperature sensor is installed inside the preparation tank 2. The temperature sensor can monitor the temperature of the slurry in real time and feed the temperature data back to the control terminal. The inner wall of the preparation box 1 is fixedly connected with a power socket 18, and the back of the preparation tank 2 is fixedly connected with a power plug 19, which is electrically connected to the power socket 18. When the preparation tank 2 is placed in the placement slot 3, the power plug 19 can automatically connect to the power socket 18 without manual wiring, and quickly realize the connection between the spiral heating tube 17 and the external power supply.

[0021] As a technical optimization of this utility model, the combination of heating chamber 16, spiral heating tube 17 and heat transfer oil can provide a stable and uniform temperature environment for slurry preparation, meeting the specific temperature requirements of hydrogen peroxide foaming gypsum reaction. At the same time, the synergistic effect of temperature sensor, power plug 19 and power socket 18 can realize automatic temperature monitoring and rapid circuit connection, improving the ease of operation of the device and the stability of slurry quality.

[0022] refer to Figure 2 and Figure 3 The inner walls of the preparation box 1 are symmetrically fixed with connecting plates 20. The connecting plates 20 provide support and guidance for the output end of the cylinder 21. The outer side of the preparation box 1 is fixedly connected with a cylinder 21. The cylinder 21 provides power for the movement of the clamping plate 22. The output end of the cylinder 21 passes through the connecting plate 20 and is fixedly connected with the clamping plate 22. The clamping plate 22 is used in conjunction with the preparation tank 2. When the preparation tank 2 is placed in the placement slot 3, the cylinder 21 can push the clamping plate 22 to move towards the tank. The clamping force of the clamping plates 22 on both sides fixes the preparation tank 2.

[0023] As a technical optimization of this utility model, the combination of connecting plate 20, cylinder 21 and clamping plate 22 can firmly fix the preparation tank 2 in the placement groove 3, avoid the tank from shifting due to vibration during the stirring process, ensure the relative position of stirring shaft 13, stirring blade 14 and tank is stable, and improve the stirring uniformity and the safety of device operation.

[0024] refer to Figure 3The connecting plate 20 has symmetrically opened limit grooves on one side facing the preparation tank 2. The limit grooves provide a moving trajectory for the limit post 23. The back of the clamping plate 22 is symmetrically fixedly connected to the limit post 23, and the limit post 23 is slidably connected to the limit groove. When the clamping plate 22 moves under the drive of the cylinder 21, the limit post 23 will slide synchronously along the limit groove.

[0025] As a technical optimization of this utility model, the sliding cooperation between the limiting groove and the limiting post 23 can limit the movement direction of the clamping plate 22, prevent the clamping plate 22 from tilting during the clamping process, ensure that the contact area between the clamping plate 22 and the outer wall of the preparation tank 2 is uniform, improve the clamping stability, and at the same time reduce the frictional loss between the clamping plate 22 and the connecting plate 20, and extend the service life of the components.

[0026] refer to Figure 2 The bottom of the placement groove 3 is symmetrically provided with a movable groove 24, which can restrict the movement trajectory of the movable wheel 25. The four corners of the bottom of the preparation tank 2 are fixedly connected with movable wheels 25, and the movable wheels 25 are in rolling connection with the movable groove 24. The movable wheels 25 can convert the sliding friction between the preparation tank 2 and the placement groove 3 into rolling friction.

[0027] As a technical optimization of this utility model, the resistance of the preparation tank 2 moving in the placement tank 3 is greatly reduced by the cooperation of the moving groove 24 and the moving wheel 25, making it easy for the operator to push the tank to complete the picking and placing. At the same time, the moving groove 24 can guide the tank to be accurately positioned, ensuring that the power plug 19 can be accurately connected to the power socket 18, improving the ease of operation and positioning accuracy of the device.

[0028] refer to Figure 1 The outer side of the preparation box 1 is hinged with a controller 26. The hinge structure allows the controller 26 to adjust the tilt angle to adapt to the usage habits of different operators. The surface of the controller 26 is provided with a human-machine interface, which can realize functions such as parameter input and operation status display. At the same time, the controller 26 is connected to the power plug 19 through the power socket 18 to control the heating power of the spiral heating tube 17.

[0029] As a technical optimization of this utility model, through the cooperation of controller 26 and human-machine interface, the operator can intuitively input parameters such as raw material ratio, stirring speed, and heating temperature. Controller 26 will automatically control the operation of components such as solenoid valve 8, rotary motor 12, and spiral heating tube 17 to realize automated control of slurry preparation. At the same time, it can display the working status of each component and slurry data in real time, which is convenient for the operator to monitor and adjust, and improve the intelligence level and operation convenience of the device.

[0030] The working principle and usage process of this utility model are as follows: When using this gypsum slurry preparation device, firstly, the operator opens the double door 4 hinged to the placement slot 3 on the front of the preparation box 1, and then pushes the preparation tank 2 so that the moving wheels 25 fixedly connected to the four corners of the bottom of the preparation tank 2 roll along the moving slots 24 symmetrically opened at the bottom of the placement slot 3, and smoothly pushes the preparation tank 2 into the placement slot 3 until the power plug 19 fixedly connected to the back of the preparation tank 2 is precisely connected to the power socket 18 fixedly connected to the inner wall of the preparation box 1, thus completing the initial positioning of the preparation tank 2. Next, the controller 26, which is hinged to the outside of the preparation box 1 and has a human-machine interface on its surface, sends a command to start the cylinder 21 fixedly connected to the outside of the preparation box 1. The output end of the cylinder 21 passes through the connecting plates 20 that are symmetrically fixedly connected to both sides of the inner wall of the preparation box 1, and drives the clamping plate 22 fixedly connected to the output end of the cylinder 21 to move towards the preparation tank 2. At this time, the limiting post 23 symmetrically fixedly connected to the back of the clamping plate 22 slides along the limiting groove symmetrically opened on the side of the connecting plate 20 toward the preparation tank 2 until the clamping plate 22 is tightly attached to the outer wall of the preparation tank 2, so as to achieve the stable fixation of the preparation tank 2. Subsequently, the hydraulic cylinder 5, fixedly connected to the center of the top of the mixing tank 1, is activated by the controller 26. The output end of the hydraulic cylinder 5 passes through the mixing tank 1 and drives the lid 6, which is adapted to the mixing tank body 2, to descend. The guide columns symmetrically fixedly connected to the top of the lid 6 slide along the mixing tank 1 to limit the movement trajectory of the lid 6. When the lid 6 approaches the mixing tank body 2, the electric push rod 7, fixedly connected in the mounting groove at the bottom of the output end of the hydraulic cylinder 5, is activated. The electric push rod 7 pushes the lid 6 to make a fine adjustment of its position, so that the lid 6 and the mixing tank body 2 are completely sealed together; thus completing the sealing process. After sealing, the feed ratio and feed amount of gypsum powder, hydrogen peroxide and other related additives are set by the controller 26. The controller 26 controls the opening of four symmetrical solenoid valves 8 connected to the top of the tank cover 6 according to the set parameters. The external feed pipe (the four feed pipes respectively transmit gypsum powder, hydrogen peroxide and other related additives) passes through the connecting flange 10 after the top of the telescopic pipe 9 connected to the input end of the solenoid valve 8 through the tank cover 6, and delivers the corresponding raw materials to the preparation tank 2 in proportion. During the conveying process, the telescopic pipe 9 can flexibly extend and retract with the position of the tank cover 6. After the raw materials are delivered, the controller 26 first closes the four solenoid valves 8, and then controls the rotary motor 12 installed inside the connecting block 11 fixedly connected to the output end of the electric push rod 7 to start. The output end of the rotary motor 12 drives the fixedly connected stirring shaft 13 to rotate through the coupling. The stirring blade 14 fixedly connected to the bottom of the stirring shaft 13 and the spiral blade 15 fixedly connected to the surface of the stirring shaft 13 rotate synchronously. The spiral blade 15 conveys the raw materials at the bottom of the preparation tank 2 upwards, and the stirring blade 14 performs radial stirring of the raw materials to achieve all-round mixing of the raw materials. Simultaneously, the controller 26 activates the spiral heating tube 17 fixedly connected inside the heating chamber 16 opened on the inner wall of the preparation tank 2. The spiral heating tube 17 heats the heat transfer oil filled inside the heating chamber 16. The heat transfer oil evenly transfers heat to the inside of the preparation tank 2. The temperature sensor installed inside the preparation tank 2 monitors the slurry temperature in real time and feeds the data back to the controller 26. The controller 26 adjusts the heating power of the spiral heating tube 17 according to the feedback data to ensure that the slurry temperature is maintained within the set range. After the slurry is prepared, the rotary motor 12 and the spiral heating tube 17 are turned off in sequence by the controller 26. Then, the cylinder 21 is reset, so that the clamping plate 22 moves away from the preparation tank 2. The limiting column 23 is reset along the limiting groove. Then, the hydraulic cylinder 5 and the electric push rod 7 are controlled to drive the tank cover 6 to rise and reset. Finally, the double door 4 is opened, the preparation tank 2 is pushed, and the moving wheel 25 rolls along the moving groove 24 to remove the preparation tank 2 containing the finished slurry from the placement groove 3, thus completing the entire gypsum slurry preparation process.
