Description

Technical Field

[0001] The utility model relates to the technical field of self - cleaning structures of feed pipes, and particularly to a mixer feed pipe with high - pressure atomizing spray. Background Art

[0002] A mixer is a machine that uses centrifugal force to perform a swirling motion to mix materials with different densities evenly in a short time. It mainly consists of a mixing container, stirring blades inside the container, a motor for driving the blades, a feed pipe, and a discharge pipe.

[0003] When the materials to be mixed enter the mixer through the feed pipe, there are situations of sticking and accumulation of materials. A suitable material for the feed pipe is beneficial to feeding. For example, using stainless - steel material makes the feed pipe have excellent corrosion - resistance performance, capable of resisting the erosion of various chemical substances, thus maintaining the smoothness of the inner wall of the feed pipe, reducing the friction and adhesion between the material and the pipe wall. Or using a polytetrafluoroethylene - coated material makes the inside of the pipe have an extremely low coefficient of friction, capable of reducing the sliding resistance and viscosity of the material in the feed pipe, making the material flow more easily.

[0004] However, when the mixer is used to mix materials with high viscosity, the materials are still likely to stick to the feed pipe of the mixer, causing blockage due to accumulation in the feed pipe and affecting the safe operation of the equipment.

[0005] In the prior art, an auxiliary vibrator is also added to help the materials enter the mixer smoothly, but it may also bring adverse effects such as material wear, noise, increased energy consumption, increased maintenance costs, and environmental protection problems.

[0006] Therefore, it is necessary to improve the prior art. Summary of the Utility Model

[0009] The spray device includes a mounting seat, several spray heads arranged on the mounting seat, and a water inlet pipe. The mounting seat is detachably connected to the top of the pipe body. One end of the water inlet pipe extends out of the pipe body and is connected to an external water source, and the other end is connected to each spray head through a branch pipe;

[0010] The material - level sensor is electrically connected to the control system of the spray device. When the material accumulation reaches a preset threshold, the spray device is started for self - cleaning.

[0011] Further, the spray head adopts a high-pressure atomizing nozzle, and the sprayed water mist is delicate and uniform, which can fully cover the inner wall of the feed pipe and effectively remove viscous materials.

[0012] Further, the level sensor adopts a high-precision and high-reliability rotary vane level sensor to ensure accurate detection of the accumulation situation of the feed.

[0013] Further, several of the spray heads are evenly distributed on the mounting seat. When multiple spraying devices are arranged at the top of the pipe body, the spraying devices are staggered to ensure that there is no dead angle for spraying.

[0014] Further, the spray head is rotatably connected to the mounting seat, and the spraying device further includes a rotating mechanism for adjusting the rotation angle of the spray head to enhance the spraying effect and cover a wider area.

[0015] Further, the rotating mechanism adopted is a gear transmission rotating mechanism, and an angle limit switch is provided to limit the rotation angle of the spray head.

[0021] The following elaborates on the preferred embodiments of the present utility model in conjunction with the drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model.

[0022] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "front", "rear", "horizontal", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and cannot indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0023] Please refer to Figure 1 and Figure 2 Figure 1 and Figure 2, the first embodiment of the present utility model provides a mixer feed pipe with high-pressure atomizing spray, including: a pipe body 1, a spray device 2 provided at the top of the pipe body 1, and a level sensor 3;

[0024] The spray device 2 includes a mounting seat 21, six nozzles 22 provided on the mounting seat 21, and a water inlet pipe 23. The mounting seat 21 is detachably connected to the top of the pipe body 1. One end of the water inlet pipe 23 extends out of the pipe body 1 and is connected to an external water source, and the other end is connected to each nozzle 22 through a branch pipe;

[0025] The nozzles 22 are evenly distributed on the mounting seat 21 and are rotatably connected to the mounting seat 21. A rotating mechanism is also built in the mounting seat 21 for adjusting the angle of the nozzles 22 to enhance the spray effect;

[0026] The level sensor 3 is electrically connected to the control system of the spray device 2 and is used to start the spray device 2 for self-cleaning when the material accumulation reaches a preset value.

[0027] Specifically, the nozzles 22 adopt high-pressure atomizing nozzles, and the sprayed water mist is delicate and uniform, which can fully cover the inner wall of the feed pipe and effectively remove sticky materials. The spray pressure and flow rate are adjusted through the control system to achieve the best cleaning effect.

[0028] The level sensor 3 adopts a high-precision and high-reliability rotary vane level sensor 3, which is installed on the right side of the spray device 2 to timely detect the material accumulation situation. The positions of the spray device 2 and the rotary vane level sensor 3 can be set according to the actual material accumulation position during the use of the mixer.

[0029] Specifically, the rotary vane level sensor 3 includes a rotating part. The sensor judges the degree of material accumulation by detecting the change in the rotation speed of the rotating part. When the spray device 2 is started, the control system adjusts the spray pressure and speed according to the numerical difference. As the accumulated material gradually decreases, the spray pressure and speed slowly decrease.

[0030] A chute is provided at the top of the pipe body 1, and the right end of the chute is closed. When installing the spray device 2, the mounting seat 21 is pushed into the chute and fixed, and then the water inlet pipe 23 is connected.

[0032] A trapezoidal groove is provided at the connection between the high-pressure atomizing nozzle and the mounting seat 21 to limit the angle of the nozzle's left and right rotation. When the nozzle rotates to the right, it points to the material piled up below the rotary vane level sensor 3.

[0033] Specifically, gaskets are provided on both sides of the trapezoidal groove to prevent the nozzle from being damaged by collision when it rotates excessively.

[0034] The rotating mechanism adopts a gear-driven rotating mechanism, which includes a gear set and a motor. The motor drives the rotation of the driving gear in the gear set, and the driving gear meshes with the driven gear to drive the nozzle 22 to rotate.

[0035] Specifically, an angle limit switch is also provided to control the starting and ending positions of the rotation to ensure the accurate rotation angle of the nozzle.

[0036] In the second embodiment of the present invention, three spray devices 2 are arranged in a staggered manner on the top of the pipe body 1 to ensure that there are no dead spots in spraying. Three water inlet pipe 23 openings are provided on the top of the pipe body 1 for arranging the corresponding water inlet pipes 23.

[0037] Specifically, the three water inlet pipes 23 converge to the water inlet main pipe and are connected to the water source through a filtering device to ensure the cleanliness of the spray water entering the feed pipe.

[0038] The rest of the design is the same as that of the first embodiment.

[0039] The beneficial effects of the feed pipe of the mixer with high-pressure atomizing spray of the present invention are as follows:

[0040] 1. Control the start and stop of the spray device according to the feed accumulation situation detected by the level sensor, reduce the viscosity of the material by spraying, clean the accumulated material in the feed pipe, and ensure the safe operation of the equipment;

[0041] 2. Set the nozzle to be rotatable left and right, enhance the spraying effect by adjusting the nozzle angle, and make the coverage area wider;

[0042] 3. One or more spray devices arranged in a staggered manner can be set according to the structure and size of the water inlet pipe to ensure that there are no dead spots in spraying.

[0043] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
