Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of modified polymer material mixing equipment, in particular to a high-stirring mixing leakage prevention alarm device. Background Art
[0002] A high-speed agitator is a high-speed agitator. In the process of preparing polymer materials, it is used to quickly stir the materials to achieve the purpose of mixing. At present, a high-speed agitator is provided with a discharge port near the bottom of the mixing bin, and a butterfly valve is installed at the discharge port. The butterfly valve is opened and closed to realize the discharge speed control.
[0003] At present, the overall height of the high-speed stirrer used by our company is 190cm, and the discharge port is too high from the horizontal ground. Therefore, in order to facilitate the mixing workers to pour and mix materials, a special placement platform is used to adjust the height of the high-speed stirrer, so that the platform where the mixer stands when feeding is 40-50cm away from the discharge port, so that the materials can be directly put into the equipment; when the platform where the mixer is located is 40-50cm away from the discharge port, the height of the high-speed stirrer below the mixer's feeding platform is 140-150cm, and the discharge port is located at the bottom of the high-speed stirrer. Therefore, It is difficult for the mixer standing on the material discharging platform to directly determine the opening and closing status of the discharge port from the platform position, and the stirring wings of the stirring device can easily block the position of the butterfly plate in the butterfly valve, further affecting the mixer on the feeding platform to observe the opening and closing status of the butterfly valve. When the butterfly plate is not tightly closed and the mixer is mixing at high speed, it is easy to cause material leakage, which not only causes material waste, but also affects the material composition and even product quality. Therefore, the mixer usually needs to go down the stairs to the discharge port to make a judgment, and the process of climbing up and down increases the work intensity.
[0004] Based on the above problems existing in the current factory equipment, it is of great significance for factory production to improve the existing high-speed agitator to improve the performance of the equipment, increase the reuse rate of the equipment and reduce the production cost. Summary of the invention
[0005] In view of this, the utility model provides a high-stirring material leakage prevention alarm device, specifically a material leakage prevention alarm device provided with a position sensor, a controller and an alarm light. The material leakage prevention alarm device has the advantages of reasonable design, strong practicality and convenient use. The use of the alarm device can effectively reduce the staff's observation of the discharge port upstairs and downstairs, reduce labor intensity, and ensure that the discharge port is in a closed state during the feeding and mixing process.
[0006] On the basis of the prior art, the utility model provides a high-stirring material leakage prevention alarm device, comprising a stirring bin; a stirring device is arranged on the stirring bin;
[0007] A discharge port is provided on the side of the mixing bin, and the discharge port is close to the bottom of the mixing bin;
[0008] A sealing head is installed at the discharge port, and the sealing head cooperates with the discharge port to seal the discharge port;
[0009] A gantry is installed outside the discharge port, and the axis of the discharge port passes through the center point of the gantry crossbar;
[0010] A cylinder is fixed on the outer side of the crossbar of the gantry, and the telescopic rod of the cylinder passes through the crossbar of the gantry and is connected to the center position of the head;
[0011] When the telescopic rod pushes the sealing head to seal the discharge port, the distance between the end of the telescopic rod in the cylinder and the crossbar of the gantry is recorded as S, in cm;
[0012] A position sensor is fixed on the outside of the cylinder, and the distance between the position sensor and the gantry crossbar is recorded as D, in cm; where DS ≥ 1 cm;
[0013] An alarm light and a controller are fixed on the top of the mixing bin; the position sensor and the alarm light are electrically connected to the controller;
[0014] When the position sensor detects the telescopic rod, it sends a signal to the controller, and the controller sends a signal to the alarm light, which flashes. At this time, the staff standing at the mixing bin observes that the discharge port is not completely blocked, so they start the cylinder and the telescopic rod drives the seal head to block the discharge port.
[0015] Preferably, slide rails are provided on the relative inner sides of the two vertical rods of the gantry, and sliders are provided on the sides of the head. The sliders are used in conjunction with the slide rails to avoid deformation of the head when the telescopic rod of the cylinder drives the head to move, thereby ensuring the sealing effect of the head.
[0016] Preferably, the stirring device includes a motor, the output shaft of the motor is connected to the stirring shaft through a belt, the top of the stirring shaft passes through the bottom of the stirring bin and enters the stirring bin, and stirring wings are provided on the stirring shaft; the motor drives the stirring shaft to rotate to achieve stirring of the material in the stirring bin.
[0017] Preferably, a feeding port is provided on the top of the mixing bin, and an alarm light is located on one side of the feeding port; this arrangement enables the staff to intuitively see the status of the alarm light when feeding.
[0018] Compared with the prior art, the beneficial effect of the utility model is that by setting a position sensor, the position of the telescopic rod can be detected; when S gradually increases, the telescopic rod will enter the detection range of the position sensor, and when the position sensor detects the telescopic rod, it will send a signal to the controller, and the controller will send a signal to the alarm light, and the alarm light will sound an alarm; since the height of the high-speed mixer is above 6m, it is usually between two floors. Therefore, during the feeding process, when the alarm light sounds, the cylinder is started downstairs to seal the discharge port, which can reduce the number of times the operator goes up and down the stairs, thereby reducing the labor intensity; in addition, by setting S and D, it can also ensure real-time monitoring of the discharge port of the mixing bin, ensure the sealing of the mixing bin, thereby avoiding material loss and improving product quality. The anti-mixing leakage alarm device has the advantages of reasonable design, strong practicality and easy use; the use of the anti-mixing leakage alarm device can effectively reduce the labor intensity of the operators, and can effectively monitor the opening and closing status of the discharge port in real time.
