Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot mixer technology, and specifically to a hot mixer that prevents sticking to the wall. Background Technology
[0002] High-speed heating mixers, or high-speed mixers for short, are widely used plastic mixing equipment. They can be used for color mixing of plastics, initial mixing before material preparation, batching, and premixing of mixed materials. They are also more suitable for powder preparation. The mixing chamber of a high-speed mixer is jacketed and can be heated. The stirring paddle can be single-layered or multi-layered.
[0003] Currently, a Chinese patent discloses a material mixer (authorization announcement number CN219922820U). By rotating the lifting component, stirring shaft, stirring blades, and brush, the material can be stirred during mixing, preventing the material from adhering to the inner wall of the three-dimensional mixer. During cleaning, the inner wall of the three-dimensional mixer can be brushed from top to bottom, achieving simultaneous stirring and brushing, which can quickly clean the inner wall of the three-dimensional mixer, improve the cleanliness of the inner wall, and reduce the cleaning time.
[0004] According to the aforementioned references, in the above-mentioned device, the stirring shaft and stirring blades drive the brush to rotate and move up and down simultaneously. By rotating the lifting component, stirring shaft, stirring blades, and brush, the materials can be stirred during mixing, preventing them from adhering to the inner wall of the three-dimensional mixer. During cleaning, the inner wall of the three-dimensional mixer can be brushed up and down. However, when the device uses the stirring shaft and stirring blades to drive the brush to clean the mixer, the brush's cleaning effect on the inner wall of the mixer is not ideal, and material is easily left inside the mixer. This makes it inconvenient to clean the material residue on the inner wall of the mixer, reducing the effectiveness of the device.
[0005] Based on this, the present invention designs a non-stick wall hot mixer to solve the above problems. Utility Model Content
[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a heat mixer that prevents sticking to the wall.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A heat mixer with anti-sticking mechanism includes a base, a tank fixedly connected to the top of the base, a cover plate installed on the top of the tank, and a cleaning mechanism disposed on the inner wall of the tank. A rotating rod is rotatably connected to the middle of the inner wall of the tank, and scrapers are fixedly connected to both sides of the rotating rod. A guide tube is fixedly connected to the bottom of the cover plate, and the bottom of the guide tube is connected to several evenly arranged nozzles. A heating component is disposed on the inner wall of the tank.
[0009] Furthermore, the cleaning mechanism also includes a cleaning brush fixedly connected to one side of the scraper, with one end of the cleaning brush fitting against the inner wall of the tank.
[0010] Furthermore, one side of the conduit is connected to a connecting tube, one end of which extends through to the outer wall of the cover plate.
[0011] Furthermore, several uniformly arranged stirring rods are fixedly connected to the outer wall of the rotating rod, and the stirring rods are installed in an alternating manner.
[0012] Furthermore, the stirring rod is positioned between the two scrapers.
[0013] Furthermore, a motor is installed on the inner wall of the base, and the output shaft at one end of the motor is fixedly connected to the rotating rod.
[0014] Furthermore, the heating assembly includes a liner fixedly connected to the inner wall of the tank, the inner wall of which is respectively attached to a scraper and a cleaning brush.
[0015] Furthermore, the inner wall of the tank is equipped with several evenly arranged heating rods.
[0016] Furthermore, a heating plate is installed on one side of the inner wall of the scraper.
[0017] Furthermore, a discharge pipe is connected to one side of the bottom of the tank, and one end of the discharge pipe passes through the tank body and the inner lining in sequence.
[0018] Beneficial effects
[0019] 1. When cleaning residual materials inside the hot mixer, the inner lining of the tank is made of polished stainless steel, which reduces the roughness of the inner wall. The rotating rod drives two scrapers to clean and remove materials adhering to the lining. The cleaning brush, made of PEEK bristles, is used to clean the materials adhering to the lining as the scrapers rotate. The PEEK bristles have low adsorption for sticky materials, reducing residue. The high temperature resistance of the PEEK bristles improves the effectiveness of the cleaning brush. The conduit can be connected to an external water source through a connecting pipe, and the spray nozzle can be used to rinse the materials adhering to the inner wall of the lining. The stirring rod can increase the shearing force of the hot mixer on the materials, reduce material adhesion, and clean the materials adhering to the inner wall of the hot mixer, improving the anti-sticking effect of the hot mixer.
[0020] 2. When the scraper cleans the material adhering to the lining, the heating plate on one side of the inner wall of the scraper can heat the material adhering to the lining, making it easier for the scraper to clean the remaining material. The heating rod on the inner wall of the tank can heat the hot mixer evenly, reducing the material residue on the lining. The cleaned material is discharged through the discharge pipe in combination with the water flow, which can improve the cleaning effect of the hot mixer. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0029] The present invention will be further described below with reference to the embodiments.
[0030] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 A heat mixer with anti-sticking mechanism includes a base 100, a tank 200 fixedly connected to the top of the base 100, a cover plate 300 installed on the top of the tank 200, and a cleaning mechanism 400 disposed on the inner wall of the tank 200. A rotating rod 410 is rotatably connected to the middle of the inner wall of the tank 200, and scrapers 420 are fixedly connected to both sides of the rotating rod 410. A conduit 430 is fixedly connected to the bottom of the cover plate 300, and several evenly arranged nozzles 440 are connected to the bottom of the conduit 430. A heating component 490 is disposed on the inner wall of the tank 200.
[0031] It should be noted that the mixing tank in the hot mixer consists of a chassis, a shell, and a top cover. Rotating blades are mounted on a main shaft inside the shell to mix the materials. The main shaft is driven by a motor within the transmission device, providing stable power to the hot mixer. Cooling and heating devices control the temperature during material mixing. When mixing rubber and plastic materials in the hot mixer, materials are prone to sticking to the inner wall of the mixer. The base 100, tank 200, and cover 300 constitute the mixing tank in the hot mixer. The liner 491 is installed inside the tank 200 as the inner wall of the mixing tank. To reduce material adhesion and ensure normal mixing effect of the hot mixer, scraper 420 and cleaning brush 450 are set on both sides of the rotating shaft. As the blades rotate, they improve the mixing effect of the hot mixer while cleaning the adhering impurities. Heating rod 492 can provide auxiliary heating for the hot mixer. Spray nozzle 440 and guide tube 430 are set at the bottom of cover plate 300 at a certain distance from the material to prevent the material from sticking to the spray nozzle 440 during mixing. When cleaning the hot mixer, water is sprayed to rinse the adhering material without affecting the normal operation of the hot mixer.
[0032] When the drive motor 480 drives the rotating rod 410 to rotate via the transmission device, it drives the two scrapers 420 to rotate as well, which can scrape and clean the material adhering to the lining 491, reducing the adhesion of the material. During cleaning, the connecting pipe 460 is connected to an external water source and water is delivered to the nozzle 440 through the conduit 430. The water jet from the nozzle 440 can rinse the residual material on the lining 491, improving the cleaning effect of the hot mixer on the adhering material and reducing the phenomenon of material sticking to the wall.
[0033] In some embodiments, such as Figure 2 and Figure 3As shown, in a preferred embodiment of the present invention, the cleaning mechanism 400 further includes a cleaning brush 450 fixedly connected to one side of the scraper 420, and one end of the cleaning brush 450 is in contact with the inner wall of the tank 200.
[0034] As the scraper 420 rotates inside the liner 491, the two cleaning brushes 450 rotate along with the two scrapers 420, which can clean the material adhering to the liner 491 and improve the anti-sticking effect of the hot mixer.
[0035] In this embodiment of the utility model, a connecting pipe 460 is connected to one side of the conduit 430, and one end of the connecting pipe 460 extends through to the outer wall of the cover plate 300.
[0036] When the nozzle 440 sprays water, the connecting pipe 460 can provide water to the nozzle 440 by connecting to an external water source, to rinse the material adhering to the inner wall of the liner 491, and effectively clean the residual material in the hot mixer in conjunction with the cleaning brush 450 and scraper 420.
[0037] In this embodiment of the invention, several uniformly arranged stirring rods 470 are fixedly connected to the outer wall of the rotating rod 410, and the stirring rods 470 are installed in an alternating manner.
[0038] When the rotating rod 410 rotates via the motor 480, it drives multiple stirring rods 470 to rotate, which can uniformly mix the materials in the hot mixer, increase the shearing force of the hot mixer, and reduce the stickiness of the materials.
[0039] In this embodiment of the invention, the stirring rod 470 is disposed between the two scrapers 420.
[0040] Multiple stirring rods 470 are located between two scrapers 420. When mixing materials, the stirring rods 470 and scrapers 420 rotate simultaneously with the rotating rod 410 to mix the materials. The scrapers 420 scrape off the materials adhering to the liner 491, reducing adhesion to the wall and improving the processing effect of the hot mixer.
[0041] In this embodiment of the utility model, a motor 480 is installed on the inner wall of the base 100, and the output shaft of one end of the motor 480 is fixedly connected to the rotating rod 410.
[0042] The motor 480 is driven by a transmission device, which can drive the stirring rod 470 and scraper 420 on the rotating rod 410 to rotate and process the material.
[0043] In some embodiments, such as Figure 2 and Figure 4As shown, in a preferred embodiment of the present invention, the heating assembly 490 includes an inner liner 491 fixedly connected to the inner wall of the tank 200, and the inner wall of the inner liner 491 is respectively attached to the scraper 420 and the cleaning brush 450.
[0044] The material enters the liner 491 inside the tank 200 through the feed port on the cover plate 300. The smooth inner wall of the liner 491 can reduce the adhesion of the material.
[0045] In this embodiment of the invention, several heating rods 492 are evenly arranged on the inner wall of the tank 200.
[0046] Heating rods 492 are evenly distributed around the hot mixer. The heating rods 492 are energized by an external controller to provide auxiliary heating to the hot mixer and improve the uniformity of material heating.
[0047] In this embodiment of the invention, a heating plate 493 is installed on one side of the inner wall of the scraper 420.
[0048] The heating plate 493 is powered on and heated by external control. The heating plate 493 can heat the scraper 420 and contact the material adhering to the liner 491 to heat it, thereby improving the cleaning effect of the scraper 420 on the material.
[0049] In this embodiment of the utility model, a discharge pipe 494 is connected to one side of the bottom of the tank body 200, and one end of the discharge pipe 494 passes through the tank body 200 and the inner lining 491 in sequence.
[0050] When cleaning the hot mixer, the solenoid valve on the discharge pipe 494 is opened by the external controller, and the material residue and wastewater cleaned out of the hot mixer are discharged out of the hot mixer through the discharge pipe 494.
