Description
Technical Field
[0001] The utility model relates to the technical field of bellows mixing, in particular to a mixing device for double-wall bellows mixture. Background Art
[0002] The double-wall bellows is a new type of pipe with an annular outer wall and a smooth inner wall, which was first developed successfully in Germany in the early 1980s. After more than a decade of development and improvement, it has developed from a single variety to a complete product series. At present, the production process and application technology are very mature. Due to its excellent performance and relatively economical cost, it has been greatly popularized and applied in developed countries such as Europe and the United States. In China, the popularization and application of HDPE double-wall bellows are in an upward trend, and all technical indicators meet the use standards. The inner wall color of the double-wall bellows is usually blue and black, and some brands use yellow for the inner wall. In order to facilitate the mixing of materials during the production of double-wall bellows, various raw materials need to be fully mixed during the processing of double-wall bellows, and then heated and extruded through a screw extrusion mechanism, and then molded by die pressing. In the prior art, the mixing of raw materials mostly relies on a mixer. The existing mixer usually mixes the raw materials by placing them in a cylinder and then stirring them up and down by a vertically arranged stirring rod. However, the existing mixing equipment has problems such as uneven stirring and slow heating during the up-and-down stirring, and it cannot better dry and stir the raw materials during the mixing process. Content of the Utility Model
[0003] Aiming at the deficiencies of the prior art, the technical problem solved by the utility model is to provide a mixing device for double-wall bellows mixture, which solves the problems of poor drying effect, uneven stirring and slow heating in the prior art.
[0004] To solve the above problems, the technical solution adopted by the present utility model is as follows: A mixing device for double-wall corrugated pipe mixture, characterized in that it includes a base, on which a plurality of support frames are provided, and corresponding support wheels are provided on the support frames; at the upper end of the support frame, there is a mixing barrel with a heat-insulating layer, and a fixing ring is provided on the mixing barrel, and the fixing ring is connected to the support wheel in a rolling manner; on the surface of the mixing barrel, there is a gear, and a reduction motor is provided at a position directly below the gear, and the reduction motor is drivingly connected to the gear; inside the mixing barrel, there is a spiral stirring blade, and a plurality of temperature sensors are fixedly provided on the spiral stirring blade; on one side of the mixing barrel, there is a heater, and the heater is communicated with a sealing door provided at one end of the mixing barrel through a connecting pipe; a sealing cover is provided on the mixing barrel at the end far from the sealing door, and a feed inlet is provided on the sealing cover, and a support is provided on one side of the feed inlet, a slide rail is provided on the support, a hopper is provided on the slide rail, and a roller is provided at the lower end of the hopper and is connected to the slide rail in a matching manner; a connecting cable is fixedly provided at the upper end of the hopper, and after the connecting cable bypasses the roller on the support, it is fixedly connected to the motor at the lower end of the support; a discharge port is provided at the bottom of the hopper; a controller is provided on one side of the mixing barrel, and the controller is electrically connected to the heater and the temperature sensor.
[0005] The technical principle of this solution is: The controller controls the motor to control the up and down sliding of the hopper for feeding. After the mixture enters the mixing barrel, the rotation of the mixing barrel is controlled by starting the reduction motor, and then the mixture in the mixing barrel is stirred. And during the stirring process, it is heated by the heater, and the hot air is introduced into the mixing barrel, so that the mixture in the mixing barrel is stirred and mixed more evenly.
[0006] The beneficial effects of this solution are: The connecting cable provided on the hopper provided on the support is connected to the motor, and the work of the motor is controlled by the controller, and then the lifting of the hopper is controlled. When the hopper rises above the feed inlet, the discharge port at the lower end of the hopper opens, and the mixture enters the feed inlet and then enters the mixing barrel for stirring. When stirring, the mixing barrel is heated by the heater, and the mixing barrel is driven by the reduction motor. The rotation speed of the reduction motor can be controlled by the controller, and then the rotation speed of the mixing barrel can be controlled, with good flexibility. And four support wheels are provided at the bottom position of the mixing barrel and are in rolling connection with the support rings at both ends of the mixing barrel, so that while the mixing barrel has good stability, the friction during the rotation process is reduced, the wear of the equipment is reduced. At the same time, the hopper is controlled by the controller to control the motor, and then the sliding of the hopper on the support is controlled, which is convenient for feeding into the mixing barrel and reduces the working intensity.
[0007] Furthermore, a plurality of through holes are provided on the spiral stirring blade, and the through holes are annularly arranged on the spiral stirring blade. The plurality of through holes provided can make the hot air circulate more smoothly inside the mixing barrel, increase the heat absorption area of the mixture, and improve the stirring efficiency.
[0008] Furthermore, there are two slide rails, which are arranged in parallel on both sides of the bracket. The two parallel slide rails ensure that the hopper will not shift during the up-and-down sliding, providing better safety.
[0009] Furthermore, the temperature sensor is arranged at the middle position of the spiral stirring blade. Arranging it at the middle position can better judge the actual temperature of the mixture during the stirring process. If it is arranged near the bottom of the stirring cylinder, the detected temperature is likely to be the temperature of the surface of the stirred mixture. If it is arranged at the upper end position of the spiral stirring blade, when there is less mixture, the sensor may not contact the mixture during the stirring process, and the detected temperature may not be the actual temperature of the mixture.
[0010] Furthermore, the controller is electrically connected to the motor.
[0011] Furthermore, a sealing connection ring is arranged at one end of the stirring cylinder near the feed inlet. One end of the sealing connection ring is connected to the stirring cylinder in a matching manner, and the other end is fixedly connected to the sealing cover. The arranged sealing connection ring prevents the feed inlet from rotating with the rotation of the stirring cylinder, thus affecting the stirring of the stirring cylinder.
