Description

Technical Field

[0001] The utility model belongs to the technical field of plastic color mixers, and particularly relates to a plastic color mixer which is convenient for cleaning residuals. Background Art

[0002] The plastic color mixer puts plastic particles of different colors and stirs them, causing them to roll, collide and rub at high speed to achieve uniform color distribution and dry the material. When heated, the plastic particles become more sticky and part of them come into contact with the inner wall of the mixer tank, causing adhesion. Cleaning is required after mixing.

[0003] The cleaning methods of the color mixer tank can be divided into two types according to the direction, as follows:

[0004] First, horizontal scraping: erect a number of scrapers on the inner wall of the mixer tank, and rotate these scrapers horizontally after mixing to scrape off the attached plastic particles. However, these scrapers will block the subsequent plastic particles inside the mixer tank, so they are rarely used;

[0005] Second, vertical scraping: a steel ring is set inside the mixer tank, close to the inner wall, and the steel ring is raised and lowered vertically after mixing to scrape off the attached plastic particles.

[0006] When the plastic color mixer cleans the residual plastic particles, the plastic particles attached to the inner wall of the tank are scraped off vertically to keep the inner wall of the tank flat. However, the steel ring needs to be pushed at multiple points and the steel ring covers a relatively wide area, making it difficult to concentrate the downward push on the plastic particles. It takes several pushes to scrape them off, which is not convenient for one-time cleaning of the residual plastic particles on the inner wall. For this reason, we propose a plastic color mixer that is easy to clean the residual. Utility Model Content

[0007] The utility model aims to provide a plastic color mixer which is convenient for cleaning residual plastics, and surrounds the inner wall of the mixing tank with a downward flushing high-pressure water jet, which can concentrate on the residual plastic particles, so as to facilitate the one-time cleaning of the residual plastic particles.

[0008] The technical solutions adopted in this utility are as follows:

[0009] A plastic color mixer convenient for cleaning residual plastics comprises a stirring tank and a tank cover connected to an opening of the stirring tank, a rotating mechanism is arranged on a lower wall of the tank cover, a compression nozzle and a hard pipe are arranged horizontally inside the stirring tank, a central axis of the compression nozzle is parallel to the central axis of the stirring tank, the hard pipe is fixedly connected to the rotating mechanism, a lower end of the hard pipe is connected to a water inlet of the compression nozzle, a rotating motor is fixed on an upper surface of the tank cover, an output end of the rotating motor passes through the tank cover and is fixedly connected to the rotating mechanism, a rotating joint is fixedly penetrated and fixed in the middle of the tank cover along an axial direction, a lower end of the rotating joint is connected to an upper end of the hard pipe, when cleaning the stirring tank, a water source is turned on, water is pumped to the compression nozzle along the rotating joint and the hard pipe, a high-pressure water jet is formed after being compressed by the compression nozzle, and the water jet is flushed downward along the inner wall of the stirring tank, and then the rotating motor is started to drive the rotating mechanism, so as to drive the compression nozzle and the hard pipe to rotate unidirectionally around the rotating joint, so that the high-pressure water jet surrounds the inner wall of the stirring tank, and can act on the residual plastic particles in a concentrated manner, and instantly flush the plastic particles attached to the inner wall of the stirring tank with a strong impact, so as to facilitate one-time cleaning of the residual plastic particles.

[0010] A feed pipe is also fixed through the upper surface of the tank cover at a position away from the rotating motor. Various plastic particles can be put in by opening the feed pipe. The feed pipe is vertically staggered from the compression nozzle to prevent the falling plastic particles from hitting the compression nozzle. The feed pipe is closed when the plastic particles are stirred.

[0011] The rotating mechanism includes a driving gear rotatably connected to the lower wall of the tank cover, the middle of the upper surface of the driving gear is fixedly connected to the output end of the rotating motor, a gear ring meshing with the driving gear is fixed on the upper surface of the hard tube, the central axis of the gear ring coincides with the central axis of the rotating joint, and the rotating motor drives the hard tube to rotate along the driving gear and the gear ring, which can drive the compression nozzle to change the water outlet position. Since the number of teeth of the driving gear and the gear ring is relatively small, the gear ring drives the hard tube to rotate at a low speed, wherein the rotating motor can select a reduction motor to control the rotation speed of the compression nozzle within a smaller range, so that the high-pressure water jet can flush the residual plastic particles in a sufficient period of time, and the gear ring can also straighten the hard tube and buffer the reaction of the high-pressure water jet on the compression nozzle and the hard tube.

[0012] An arc groove is provided on the inner edge of the mixing tank, and the arc groove is used to accommodate the compression nozzle so that the water outlet of the compression nozzle can be close to the inner wall of the mixing tank, so that the high-pressure water jet is close to the inner wall of the mixing tank and acts on the residual plastic particles as much as possible.

[0013] A high-pressure water pump is arranged outside the mixing tank, and the output end of the high-pressure water pump is connected to the upper end of the rotary joint. The high-pressure water pump sucks water from the water source. When cleaning, the high-pressure water pump is started to pressurize the sucked water to the compression nozzle, thereby providing sufficient pressurization for the high-pressure water jet.

[0014] The lower end of the stirring tank is connected and fixed with a feed pipe. When the plastic particles are stirred, the feed pipe is closed, and then the feed pipe is opened, and the plastic particles and waste water can be discharged from the feed pipe.

[0015] The technical effects achieved by this utility model are:

[0016] The utility model discloses a color mixer which is convenient for cleaning residual plastic. When cleaning the mixing tank, the water source is turned on, and water is pumped to the compression nozzle along the rotating joint and the hard pipe. The water is compressed by the compression nozzle to form a high-pressure water jet, which is washed downward along the inner wall of the mixing tank. Then the rotating motor is started to drive the rotating mechanism, so as to drive the compression nozzle and the hard pipe to rotate unidirectionally around the rotating joint, and the high-pressure water jet surrounds the inner wall of the mixing tank, which can concentrate on the residual plastic particles, and instantly wash away the plastic particles attached to the inner wall of the mixing tank with a strong impact, so as to facilitate the one-time cleaning of the residual plastic particles.

[0023] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0024] like Figure 1-4As shown, a plastic color mixer that is easy to clean up residuals includes a stirring tank 1 and a tank cover 2 connected to the opening of the stirring tank 1. The reference publication number is CN213890750U, a Chinese utility model for a plastic production and processing color mixer that is easy to clean up residuals. The stirring tank 1 is provided with a plurality of first stirring rods and a pair of second stirring rods. This technical solution is a prior art and is not drawn in the figure. The lower wall of the tank cover 2 is provided with a rotating mechanism. The inside of the stirring tank 1 is provided with a compression nozzle 3 and a hard pipe 4 along the horizontal direction. The central axis of the compression nozzle 3 is parallel to the central axis of the stirring tank 1. The hard pipe 4 It is fixedly connected to the rotating mechanism, the lower end of the hard tube 4 is connected to the water inlet of the compression nozzle 3, a rotating motor 5 is fixed on the upper surface of the tank cover 2, the output end of the rotating motor 5 passes through the tank cover 2 and is fixed to the rotating mechanism, a rotating joint 6 is fixedly passed through the middle of the tank cover 2 along the axial direction, the upper end of the rotating joint 6 is connected to the water source, and the lower end of the rotating joint 6 is connected to the upper end of the hard tube 4. First, add an appropriate amount of plastic particles to the mixing tank 1, and rotate a plurality of first stirring rods and a pair of second stirring rods through the stirring motor to make the plastic particles roll, collide and rub at high speed to achieve uniform color distribution and material drying. After being heated, the plastic particles have increased viscosity, and part of them contact the inner wall of the color mixer tank, causing adhesion, and need to be cleaned after mixing. When cleaning the mixing tank 1, turn on the water source, pump water to the compression nozzle 3 along the rotary joint 6 and the hard pipe 4, compress the water through the compression nozzle 3 to form a high-pressure water jet, and flush downward along the inner wall of the mixing tank 1. Then start the rotary motor 5 to drive the rotating mechanism, drive the compression nozzle 3 and the hard pipe 4 to rotate unidirectionally around the rotary joint 6, and surround the inner wall of the mixing tank 1 with the high-pressure water jet, so as to concentrate on the residual plastic particles, and instantly flush off the plastic particles attached to the inner wall of the mixing tank 1 with a strong impact, so as to facilitate the one-time cleaning of the residual plastic particles.

[0025] In this way, after the flushing is completed, the water source is turned off, the high-pressure water jet disappears, and will not hinder the subsequent plastic particles in the mixing tank 1. In addition, the compression nozzle 3 is suspended high in the mixing tank 1 and will not contact the stirred plastic particles.

[0026] like Figure 1 As shown, a feed pipe 7 is fixedly passed through the upper surface of the tank cover 2 at a position away from the rotating motor 5. Various plastic particles can be put into the tank cover 2 by opening the feed pipe 7. The feed pipe 7 is vertically staggered from the compression nozzle 3 to prevent the falling plastic particles from hitting the compression nozzle 3. The feed pipe 7 is closed when the plastic particles are stirred.

[0027] like Figure 2 , Figure 3 and Figure 4As shown, the rotating mechanism includes a driving gear 8 rotatably connected to the lower wall of the tank cover 2, the middle of the upper surface of the driving gear 8 is fixedly connected to the output end of the rotating motor 5, and a gear ring 9 meshing with the driving gear 8 is fixed on the upper surface of the hard tube 4. The upper surface of the gear ring 9 is rotatably connected to the lower wall of the tank cover 2, and the central axis of the gear ring 9 coincides with the central axis of the rotating joint 6. The rotating motor 5 drives the hard tube 4 to rotate along the driving gear 8 and the gear ring 9, which can drive the compression nozzle 3 to change the water outlet position. Since the number of teeth of the driving gear 8 and the gear ring 9 is relatively small, the gear ring 9 drives the hard tube 4 to rotate at a low speed. Among them, the rotating motor 5 can use a reduction motor to control the rotation speed of the compression nozzle 3 within a smaller range, so that the high-pressure water jet can flush the residual plastic particles in a sufficient period of time. The gear ring 9 can also straighten the hard tube 4 and buffer the reaction of the high-pressure water jet on the compression nozzle 3 and the hard tube 4.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, an arc groove 10 is provided on the inner edge of the mixing tank 1, and the arc groove 10 is used to accommodate the compression nozzle 3, so that the water outlet of the compression nozzle 3 can be close to the inner wall of the mixing tank 1, so that the high-pressure water jet is close to the inner wall of the mixing tank 1 and acts on the residual plastic particles as much as possible.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, a high-pressure water pump 11 is arranged outside the mixing tank 1. The high-pressure water pump 11 can select a KDG type cold and hot water pipe centrifugal pump. The output end of the high-pressure water pump 11 is connected to the upper end of the rotary joint 6. The high-pressure water pump 11 sucks water from the water source. When cleaning, the high-pressure water pump 11 is started to pressurize the sucked water to the compression nozzle 3, providing sufficient pressurization for the high-pressure water jet.

[0030] like Figure 1 and Figure 2 As shown, a feed pipe 12 is connected and fixed to the lower end of the mixing tank 1. When the plastic particles are mixed, the feed pipe 12 is closed, and then the feed pipe 12 is opened, and the plastic particles and waste water can be discharged from the feed pipe 12.

[0031] The working principle of the utility model is as follows: when cleaning the mixing tank 1, the water source is turned on, and water is pumped to the compression nozzle 3 along the rotating joint 6 and the hard pipe 4. The water is compressed by the compression nozzle 3 to form a high-pressure water jet, which is flushed downward along the inner wall of the mixing tank 1. Then, the rotating motor 5 is started to drive the rotating mechanism, which drives the compression nozzle 3 and the hard pipe 4 to rotate unidirectionally around the rotating joint 6, and the high-pressure water jet surrounds the inner wall of the mixing tank 1, which can concentrate on the residual plastic particles, and instantly flush off the plastic particles attached to the inner wall of the mixing tank 1 with a strong impact, so as to facilitate the one-time cleaning of the residual plastic particles.

[0032] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
