Abstract
Description
Technical Field
[0001] This utility model relates to the field of gypsum powder production technology, and in particular to a gypsum powder production mixing and processing device. Background Technology
[0002] The main operation of the gypsum powder production mixing and processing device is to fully mix gypsum raw materials (such as gypsum powder obtained after crushing, screening and washing gypsum ore) with water to form a uniform gypsum slurry, which provides qualified raw materials for subsequent production steps (such as grouting, molding, drying etc.).
[0003] Currently, the ratio of gypsum powder to water is controlled by a system that injects the mixture into a mixing device. While this method can meet the requirements for qualified raw materials, it has the following drawbacks: Since water and gypsum powder are injected through two separate pipes, mixing requires the use of mixing components such as a stirring shaft. This mixing method results in excessively long processing times, while insufficient processing times may lead to some slurries being too thin and others being too hard. Therefore, we propose a gypsum powder production mixing and processing device. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, to make the injection and mixing of water and gypsum powder more coordinated and uniform, to process raw materials in a multi-stage operation and to complete the overall mixing, so as to ensure the supply of qualified raw materials while improving processing efficiency.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A gypsum powder production mixing and processing device includes a proportioning bin and a mixing bin, which are connected by a funnel frame.
[0007] The mixing bin has an opening at the top, and a receiving hopper is rotatably connected to the inner circumferential wall near the opening. A cross bracket is installed below the receiving hopper, and the receiving hopper is rotatably connected to the center point of the cross bracket via a rotating shaft. A nozzle is installed below the cross bracket, and a discharge port is opened at the bottom of the receiving hopper. A scraper is provided at the bottom of the mixing bin.
[0008] Inside the mixing chamber, a crushing roller is horizontally installed corresponding to the funnel frame connecting part. The bottom of the mixing chamber has a funnel-shaped structure, and a mixing roller is vertically installed inside the mixing chamber.
[0009] Furthermore, the distance between the two sides of the inner wall of the funnel frame is wider at the top and narrower at the bottom.
[0010] Furthermore, a powder feeding pipe is installed on one side of the top of the mixing bin, and a bracket is installed on the outer side of the mixing bin extending to the center of the top. A first motor is installed between the bracket and the receiving hopper, and the first motor is controlled to rotate forward and backward to drive the receiving hopper to rotate along the inner circumferential wall of the mixing bin.
[0011] Furthermore, the inner circumferential wall of the mixing bin is provided with an annular groove, and there are no less than two sets of annular grooves. An arc-shaped slider is slidably connected in the annular groove, and the arc-shaped slider is fixedly installed with the receiving hopper.
[0012] Furthermore, a water supply pipe is installed inside the cross bracket, which is connected to a water pump via a pipe. The water supply pipe is used to supply water to the nozzles, and the top two sides of the cross bracket are designed with chamfered corners.
[0013] Furthermore, the discharge port and the funnel frame are staggered, and the funnel frame rotates along the proportioning bin to finally correspond to the discharge port.
[0014] Furthermore, the scraper plate corresponds to the discharge port. Driven by a second motor installed at the bottom of the mixing bin, the second motor drives the scraper plate to rotate one revolution, and the scraper plate corresponds to the funnel frame.
[0015] Furthermore, the crushing roller is driven by a third motor installed inside the mixing chamber, and the mixing roller is driven by a fourth motor installed inside the mixing chamber.
[0016] Furthermore, the front of the mixing chamber is connected to the screw conveyor feeding pipe corresponding to the lowest internal point.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. Through the designed proportioning and mixing chamber structure, the coordinated injection and mixing of gypsum powder and water are achieved. The rotation of the receiving hopper in the proportioning chamber, combined with the setting of the cross support and nozzle, makes the mixing of gypsum powder and water more uniform, avoiding the problem of uneven mixing in the traditional method.
[0019] 2. The device achieves multi-stage operation through preliminary mixing in the proportioning bin, transition in the funnel frame, and further crushing and mixing in the mixing bin. This process not only improves mixing efficiency but also ensures the uniformity of the gypsum slurry, providing qualified raw materials for subsequent production steps.
[0020] 3. Due to the adoption of a more efficient mixing method and multi-stage operation process, the processing time of the gypsum powder production mixing and processing device of this utility model has been significantly shortened. At the same time, by precisely controlling the ratio of gypsum powder to water and the mixing process, the consistency of the slurry quality is ensured, thereby improving the overall processing efficiency.

[0039] Example 1
[0040] like Figure 1-4 As shown, this utility model provides a technical solution: a gypsum powder production mixing and processing device, including a proportioning bin 1 and a mixing bin 2, which are connected by a funnel frame 3;
[0041] The mixing chamber 1 is used to receive and initially mix gypsum powder and water. The mixing chamber 1 has an opening at the top, and a receiving hopper 11 is rotatably connected to the inner circumferential wall near the opening. A cross bracket 12 is installed below the receiving hopper 11. The receiving hopper 11 is rotatably connected to the center point of the cross bracket 12 via a rotating shaft. A nozzle 13 is installed below the cross bracket 12. A discharge port 14 is opened at the bottom of the receiving hopper 11. A scraper 15 is provided at the bottom of the mixing chamber 1.
[0042] The mixing chamber 2 is used to further crush and mix the gypsum powder mixture. Inside, a crushing roller 21 is horizontally installed corresponding to the funnel frame 3. The bottom of the mixing chamber 2 has a funnel-shaped structure, and a mixing roller 22 is vertically installed inside the mixing chamber 2.
[0043] Example 2
[0044] like Figure 1-4 As shown, the spacing between the two sides of the inner wall of the funnel frame 3 is wider at the top and narrower at the bottom. This design facilitates the smooth flow of gypsum powder and water into the mixing chamber 2.
[0045] A powder feeding pipe 4 is installed on one side of the top of the mixing bin 1. A bracket 5 is installed on the outer side of the mixing bin 1, extending to the center of the top. A first motor 6 is installed between the bracket 5 and the cross bracket 12 and the receiving hopper 11. The first motor 6 is controlled to rotate forward and backward, driving the receiving hopper 11 to rotate along the inner circumferential wall of the mixing bin 1.
[0046] To ensure the stability of the rotation of the receiving hopper 11, the inner circumferential wall of the proportioning bin 1 is provided with an annular groove 7. There are no less than two sets of annular grooves 7. An arc-shaped slider 71 is slidably connected in the annular groove 7, and the arc-shaped slider 71 is fixedly installed with the receiving hopper 11.
[0047] The cross bracket 12 has a water supply pipe 8 installed inside. The water supply pipe 8 is connected to the water pump through a pipe. The water supply pipe 8 is used to supply water to the nozzle 13. The top of the cross bracket 12 has a chamfered design on both sides to prevent the accumulation of gypsum powder on the cross bracket 12.
[0048] The discharge port 14 and the funnel frame 3 are staggered. The funnel frame 3 rotates along the proportioning bin 1 and finally corresponds to the discharge port 14, which prevents the receiving hopper 11 from directly leaking gypsum powder into the funnel frame 3 through the discharge port 14 during the receiving process.
[0049] The scraper 15 corresponds to the discharge port 14. It is driven by the second motor 9 installed at the bottom of the mixing chamber 1. The second motor 9 controls the scraper 15 to rotate one revolution. The scraper 15 corresponds to the funnel frame 3. The corresponding design of the scraper 15 and the discharge port 14, as well as the scraper 15 being driven to rotate by the second motor 9, ensures that the gypsum powder can fall completely into the mixing chamber 2.
[0050] The wet mixture entering the mixing chamber 2 is crushed by the crushing roller 21 driven by the third motor 211 installed inside the mixing chamber 2, and the mixing roller 22 is finally mixed by the fourth motor 221 installed inside the mixing chamber 2.
[0051] The front of the mixing chamber 2 is connected to the lowest internal point of the screw conveyor feed pipe 23, which is connected to the downstream production line to support efficient and continuous mixing processing.
[0052] The working process of this utility model is as follows: When using a gypsum powder production mixing and processing device, the gypsum powder raw material is fed into the receiving hopper 11 through the powder feeding pipe 4. After feeding is completed, the first motor 6 is started to control the receiving hopper 11 to rotate along the inner circumferential wall of the mixing chamber 1. During the rotation, the receiving hopper 11 continuously discharges gypsum powder into the mixing chamber 1 through the discharge port 14. At the same time, the water pump supplies water to the nozzle 13 below the cross support 12 through the water supply pipe 8. The water is sprayed out from the nozzle 13 and initially mixes with the gypsum powder in the receiving hopper 11. Due to the rotation of the receiving hopper 11 and the spraying of water from the nozzle 13, the gypsum powder and water form a preliminary moist mixture in the mixing chamber 1. When the receiving hopper 11 rotates one revolution to the direction of the discharge port 14, the mixture falls from the discharge port 14 into the funnel frame 3. To ensure that the mixture is completely discharged, the second motor 9 is started to drive the scraper 15 again. As the material rotates once, the scraper 15 scrapes off the mixture remaining on the inner wall of the proportioning bin 1 and the bottom of the receiving hopper 11, ensuring that it falls into the funnel frame 3 (the proportioning process is repeated in this way). Then, the mixture falls from the funnel frame 3 into the mixing bin 2. First, it passes through the horizontally installed crushing roller 21, which is driven by the third motor 211, to further crush the mixture and ensure that its particle size is uniform. The crushed mixture falls into the bottom of the mixing bin 2, where the fourth motor 221 drives the mixing roller 22 to stir it. The stirring action of the mixing roller 22 makes the mixture more uniform. After stirring, the mixture gathers in a funnel-shaped structure at the bottom of the mixing bin 2. To facilitate the conveying and processing of the mixture, the front of the mixing bin 2 is connected to the lowest point inside, and the mixture can be continuously and stably conveyed to the subsequent production steps through the auger feeding pipe 23.
[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
