Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gypsum powder processing equipment, in particular to an automatic gypsum powder unloading system. Background Art
[0002] Gypsum board, also known as gypsum wallboard or plasterboard, is a building and decorative material primarily made of gypsum, widely used in construction and interior decoration. During the gypsum board production process, mined gypsum ore is crushed and calcined to form gypsum. The calcined gypsum is then pulverized into a powder. The gypsum powder is then weighed and mixed with water in a specific proportion to form a gypsum slurry, which is then cast into the gypsum board.
[0003] Currently, the existing technology typically uses a weighing tank to weigh gypsum powder, which is then fed into a mixing device and mixed with water in a specific proportion. To ensure accurate weighing results, the feeding of gypsum powder must be paused when the weight of the gypsum powder in the weighing tank reaches a set value, and can only be restarted after the feeding is completed. This interruption reduces work efficiency. Utility Model Content
[0004] In view of this, the purpose of the present invention is to provide an automatic gypsum powder unloading system to solve the problem that the existing weighing tank needs to pause to input gypsum powder during the unloading process, resulting in reduced work efficiency.
[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:
[0006] A gypsum powder automatic feeding system comprises a three-way valve, two weighing tanks, a feeding pipe, a breaking mechanism, and a controller; one input end of the three-way valve is used to input gypsum powder, and the other two output ends of the three-way valve are respectively connected to the tops of the two weighing tanks; a straight-through valve is respectively provided at the bottoms of the two weighing tanks, and the feeding pipe is connected to the two straight-through valves to form a three-way structure; the breaking mechanism is installed on the feeding pipe to break up the gypsum powder passing through the feeding pipe; the controller is electrically connected to the three-way valve, weighing tanks and straight-through valves; when the value measured by one of the weighing tanks reaches a preset value, the corresponding straight-through valve is opened by the controller, and the output direction of the three-way valve is switched to the other weighing tank, and the corresponding straight-through valve is closed at the same time.
[0007] As an optional solution, the breaking up mechanism includes a motor and an impeller, the motor is arranged outside the discharge pipe, and the output shaft of the motor extends horizontally into the discharge pipe; the impeller is vertically arranged in the discharge pipe and coaxially connected to the output shaft of the motor.
[0008] As an optional solution, the discharge pipe is square, the length of the inner hole of the discharge pipe is equal to the diameter of the impeller, and the width of the inner hole of the discharge pipe is equal to the thickness of the impeller.
[0009] As an optional solution, a one-way valve located above the impeller is installed on the discharge pipe.
[0010] As an optional solution, the three-way valve is a three-way solenoid valve.
[0011] As an optional solution, the through valve is a through solenoid valve.
[0012] As an optional solution, the tops of the two weighing tanks are connected to bellows, and the two bellows are respectively connected to the two output ends of the three-way valve.
[0013] Due to the adoption of the above technical solution, the utility model will have the following beneficial effects:
[0014] By providing two weighing tanks connected to three-way valves, when the gypsum powder collected in one of the weighing tanks reaches a preset value, the controller can open the through-valve corresponding to the weighing tank for unloading, and control the three-way valve to switch to the other weighing tank, while closing the through-valve corresponding to the weighing tank, so that the weighing tank can continue to collect gypsum powder. Compared with the prior art method of using a weighing tank and pausing the input of gypsum powder for unloading, the utility model can automatically and uninterruptedly unload the material to the stirring device by cyclically weighing in the two weighing tanks, thereby improving work efficiency.
[0015] Since the gypsum powder remaining inside the weighing tank is easy to clump when the weighing tank does not work for a long time, by setting a breaking mechanism on the discharge pipe, the agglomerated gypsum powder will be broken up by the breaking mechanism during the discharge process after it resumes work, thereby preventing the discharge pipe from being blocked and further improving work efficiency.

[0023] Please refer to Figure 1 In one embodiment of an automatic gypsum powder unloading system of the present invention, the automatic gypsum powder unloading system includes a three-way valve 1, two weighing tanks 2, a unloading pipe 3, a breaking mechanism 4, and a controller.
[0024] The three-way valve 1 is a "one-in, two-out" type, with one inlet and two outlets. It is typically used in systems that need to distribute fluid from a single source to two different paths. This valve allows the user to direct the fluid from one inlet to either of the two outlets by switching internal channels. One input port of the three-way valve 1 is used to input gypsum powder, while the other two output ports are connected to the tops of two weighing tanks 2. Weighing tanks 2 are a type of existing equipment used to measure and control material weight and are widely used in industrial production, chemical industry, food, pharmaceuticals, and other fields. Their primary function is to accurately measure the weight of materials during storage, batching, and weighing to ensure accuracy and consistency in the production process. A straight-through valve 5 is respectively installed at the bottom of the two weighing tanks 2, and the discharge pipe 3 is connected to the two straight-through valves 5 to form a three-way structure; the breaking mechanism 4 is installed on the discharge pipe 3 to break up the gypsum powder passing through the discharge pipe 3; the controller is electrically connected to the three-way valve 1, the weighing tank 2 and the straight-through valve 5. Specifically, the controller can adopt an existing PLC controller, the model of which can be a "Siemens" modular PLC: S7-1200. The output signal of the weighing tank 2 is connected to the input port of the PLC controller, and the output port of the PLC controller is connected to the three-way valve 1 and the straight-through valve 5.
[0025] In this embodiment, when the value measured by one weighing tank 2 reaches a preset value, the controller opens the through valve 5 corresponding to the weighing tank 2 to discharge the material, and switches the output direction of the three-way valve 1 to the other weighing tank 2, while closing the through valve 5 corresponding to the weighing tank 2. This cycle is repeated, and the input of gypsum powder does not need to be suspended during the discharge process of the weighing tank 2, thereby improving work efficiency. Since the gypsum powder remaining inside the weighing tank 2 when it is not working for a long time is easy to agglomerate, the agglomerated gypsum powder is easy to cause blockage during the discharge process after it is restarted, and the breaking mechanism 4 can break up the agglomerated gypsum powder to prevent the discharge pipe 3 from being blocked, further improving work efficiency.
[0026] like Figure 2 As shown, specifically, the breaking up mechanism 4 includes a motor 41 and an impeller 42. The motor 41 is fixedly mounted on the outer side of the upper end of the discharge pipe 3. The output shaft of the motor 41 extends horizontally into the discharge pipe 3 and is rotatably connected to the side wall of the discharge pipe 3 through a bearing; the impeller 42 is vertically arranged in the discharge pipe 3 and is coaxially connected to the output shaft of the motor 41 through a coupling. When working, the motor 41 drives the impeller 42 to rotate, and the rotation of the impeller 42 can break up the agglomerated gypsum powder falling from the weighing tank 2.
[0027] like Figure 2As shown, more specifically, the blades of the feed pipe 3 and the impeller 42 can be both set to be square, the inner hole length of the feed pipe 3 is equal to the diameter of the impeller 42, and the inner hole width of the feed pipe 3 is equal to the thickness of the impeller 42, so that the impeller 42 can fill the entire inner hole of the feed pipe 3. In this way, all the falling gypsum powder will fall on the impeller 42. The rotating impeller 42 can drive the gypsum powder to rotate downward until the gypsum powder is thrown downward. The faster the speed of the impeller 42, the faster the gypsum powder is thrown out. Therefore, the speed of the gypsum powder thrown out of the feed pipe 3 can be adjusted by controlling the speed of the impeller 42 through the motor 41. Since the feed pipe 3 feeds into the stirring device, the gypsum powder and water are mixed in a certain proportion in the stirring device. If the gypsum powder feeding speed is too fast and the instantaneous injection amount is too large, the stirring device will not work properly, affecting the stirring effect. If the feeding speed is too slow, the production efficiency will be affected. Therefore, through the above settings, the feeding speed of gypsum powder can be adjusted according to the actual production conditions, thereby taking into account both the stirring effect and the production efficiency.
[0028] like Figure 1 As shown, further, a one-way valve 6 can be installed at the upper end of the discharge pipe 3 and located above the impeller 42. The one-way valve 6 only allows the gypsum powder to move downward. Since part of the gypsum powder will fall on the blade on the side of the impeller 42 that rotates upward, this part of the gypsum powder will be thrown upward by the blade on the side. Since the one-way valve 6 can prevent the thrown gypsum powder from moving upward, the thrown part of the gypsum powder will quickly turn and move along a lower parabola, thereby pushing all the gypsum powder falling from the one-way valve 6 to the blade on the side of the impeller 42 that rotates downward, thereby increasing the gypsum powder thrown downward by the impeller 42 and improving work efficiency.
[0029] Specifically, the three-way valve 1 can be an inverted Y-shaped three-way solenoid valve. This three-way solenoid valve is an existing solenoid valve with three connection ports. It has a three-way structure with one fluid input port and two fluid output ports arranged in an inverted Y shape. The three-way solenoid valve controls the movement of the valve core through an electromagnet, thereby switching the flow direction of the fluid. Specifically, when the solenoid valve is energized, the electromagnet generates an attractive force, which attracts the valve core to move, opening or closing a specific flow channel, allowing the fluid to flow from one port to the other. When the solenoid valve is de-energized, the valve core is reset by the action of a spring, switching the flow direction of the fluid.
[0030] Specifically, through-valve 5 is a through-valve solenoid valve, a type of valve commonly used to control fluid flow. A through-valve forms a straight flow path within the valve body, and electromagnetic force is used to open and close the valve, thereby achieving automatic control of gypsum powder. Its principle is to use the magnetic field generated by the electromagnet to attract the valve core. Specifically, when the solenoid valve is energized, the magnetic field generated by the electromagnet attracts the valve core, opening the valve. Once the power is removed, the valve core returns to its original position under the action of a spring, closing the valve and thus controlling the flow of fluid.
[0031] like Figure 1 As shown, further, a bellows 8 can be connected to the top of each of the two weighing tanks 2. The two bellows 8 are respectively connected to the two output ends of the three-way valve 1. The bellows 8 is a conventional flexible pipe with a corrugated structure, which has excellent bending and expansion properties and can withstand high pressure. Because the tank body of the weighing tank 2 moves downward a distance during weighing, the provision of the bellows 8 can prevent the tension of the pipes at the two output ends of the three-way valve 1 from affecting the weighing results of the weighing tank 2.
[0032] The usage method or working principle of the utility model is as follows:
[0033] When the gypsum powder collected by one of the weighing tanks 2 reaches a preset value, the weighing tank 2 outputs an electrical signal to the PLC controller, which opens the straight-through valve 5 corresponding to the weighing tank 2 for unloading, and controls the three-way valve 1 to switch to another weighing tank 2, while closing the straight-through valve 5 corresponding to the weighing tank 2, so that the weighing tank 2 can continue to collect gypsum powder. The weighing is repeated in the two weighing tanks 2 in a cycle, and the mixing device can be automatically and uninterruptedly unloaded, thereby improving work efficiency.
[0034] When the weighing tank 2 is not in operation for a long time, the gypsum powder remaining inside the weighing tank 2 is easy to clump. After re-operation, the gypsum powder is broken up by the breaking mechanism 4 during the discharge process, thereby preventing the discharge pipe 3 from being blocked and further improving work efficiency.
[0035] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
