Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding device technology, specifically a weighing feeding device. Background Technology
[0002] Cement is an important building material, widely used in concrete production and construction projects. Its production process requires grinding raw materials into fine powder to improve its performance and quality. To ensure the stability and efficiency of cement production, the feeding system of the grinding equipment must be precise and reliable.
[0003] However, many grinding tanks currently have certain problems during the feeding process, such as material clogging within the tank, leading to uneven or interrupted feeding. Furthermore, traditional feeding systems often struggle to precisely control the material delivery rate, affecting production stability and efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a weighing and feeding device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a weighing and feeding device, comprising a tank, a first hopper, and a second hopper. The first hopper is fixed at the top of the inside of the tank, and a weight sensor is provided at the bottom of the inside of the tank. A base is provided on the surface of the weight sensor, and a support rod is connected to the surface of the base. The top of the support rod is connected to the second hopper, and the second hopper is located in the middle of the inside of the tank. A horizontal plate is fixed in the middle of the inside of the first hopper, and a motor is fixed in the middle of the horizontal plate.
[0006] When using the weighing and feeding device in this technical solution, the operator needs to first connect an external power supply to the device and control its operation through the control panel. The operator first sets the amount to be fed through the control panel. After setting, the control panel will control the first valve to open. After the first valve opens, the material temporarily stored in the first hopper will be transferred to the inside of the second hopper through the first pipe. The weight of the second hopper will be sensed by the weight sensor. When the sensed weight is the same as the weight previously set in the control panel, the control panel will control the first valve to close the discharge of the first pipe and open the second valve. The material in the second hopper will be transferred to the inside of the third pipe through the second pipe. Finally, the material will be transported to the grinding mill for processing through the third pipe. When a blockage is found in the discharge of the first hopper, the operator can turn on the motor. The output end of the motor is connected to the shaft. After the shaft rotates, the spiral blades fixed on its surface will also rotate. The rotating spiral blades will squeeze the material in the first hopper and transfer it to the first pipe, and then transfer it to the inside of the second hopper through the first pipe.
[0007] Preferably, the output end of the motor is connected to a shaft, and a helical blade is fixed on the surface of the shaft. Through the cooperation of the motor and the shaft, the helical blade can rotate inside the first hopper and the first pipe, achieving the effect of power output. By setting the helical blade, the material in the first hopper can be helically squeezed into the inside of the first pipe, achieving the effect of assisting material feeding and avoiding blockage.
[0008] Preferably, the motor has a housing on its surface. The housing protects the motor from corrosion and damage by the material temporarily stored in the first hopper.
[0009] Preferably, the top of the outer shell and the surface of the horizontal plate are both designed with a conical structure. The conical structure design ensures that the material entering the first hopper through the collection hopper will not remain on the top of the outer shell and the surface of the horizontal plate, achieving the effect of tilting and sliding to prevent accumulation.
[0010] Preferably, a first pipe is connected to the outer bottom end of the first hopper, and a first valve is installed inside the first pipe. Through the cooperation of the first pipe and the first valve, the material in the first hopper can be discharged in a controlled manner, achieving the effect of opening and closing the discharge valve.
[0011] Preferably, a second pipe is connected to the outer bottom end of the second hopper, and a second valve is installed inside the second pipe. Through the cooperation of the second pipe and the second valve, the material in the second hopper can be discharged in a controlled manner, achieving the effect of on / off material discharge.
[0012] Preferably, a third pipe is provided at the bottom end of the second pipe, one end of which is inserted into the inside of the slot, and the slot is opened at the bottom side of the tank. The slot is provided so that the third pipe for conveying materials can extend from the inside of the tank, providing an outlet discharge position and a fixed installation position. The third pipe allows the material discharged from the second hopper to be conveyed to the inside of the mill through this pipe, providing a conveying channel.
[0013] Preferably, a collection hopper is fixed in the middle of the outer top surface of the tank. By setting up the collection hopper, the material to be temporarily stored can be transferred through this hopper to the interior of the first hopper, thus providing a feeding position.
[0014] Preferably, the outer bottom surface of the tank is connected to six support legs, which are distributed in a circular, equidistant pattern. Each of the six support legs has a base plate fixed to its bottom end. The cooperation of the support legs and the base plate allows the present invention to be used stably off the ground, achieving the effect of stabilizing its placement and use.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This utility model effectively avoids the problem of material blockage by installing a first hopper with a motor-driven spiral blade at the top of the tank. The second hopper is connected to a weight sensor to ensure accurate and controllable feeding. The operator can set the quantitative feeding through the control panel, and the system automatically adjusts the valve to ensure accurate material delivery. This device improves the accuracy and stability of feeding, optimizes the material delivery in the cement production process, reduces the unevenness and interruption problems in the traditional feeding system, and improves production efficiency.
