[0002] The existing equipment for the mixing section is a mixing mechanism. A feeding hopper is connected below the mixing mechanism, and the conveying equipment below the feeding hopper is a screw conveyor or a scraper conveyor. Large lumpy materials after mixing are difficult to be discharged into the feeding hopper in the mixing mechanism. The lumpy materials in the feeding hopper accumulate and cannot enter the screw conveyor or the scraper, eventually causing blockage, unable to produce, and requiring manual cleaning.

[0003] During the production process of pet baking grains, a large amount of meat slurry, grease, and water are often added to the powder materials in the mixing section. After mixing, the materials form large lumps, and the moisture content can reach more than 40%. This leads to the accumulation of large lumpy materials after mixing, poor fluidity, and inability to enter the next production link. It is necessary to stop the machine for manual lump breaking, cleaning, and transporting to the next process, unable to produce continuously, with low efficiency, high raw material loss, and high labor intensity for workers.

The support shaft 1-22 vertically penetrates the holes on the first main shaft 1-21 and is symmetrically fixed. The adjacent two support shafts 1-22 in the axial direction of the first main shaft 1-21 are staggered by 90°. The paddle blades 1-23 are arranged at a certain angle at the tail end of the support shaft 1-22, so that the mixed materials can be sprinkled and axially convected. The angle of the end paddle blades 1-24 is opposite to the direction of other paddle blades 1-23 and is arranged in the reverse direction to prevent the materials from squeezing and accumulating on the inner wall of the mixing chamber 1-1 and can play a role in cleaning the inner wall.

[0035] The cleaning doors 1-4 are symmetrically arranged on both sides of the upper part of the mixing chamber 1-1 and are used to clean the mixing mechanism 1. Two symmetric cleaning doors are provided in the mixing mechanism, and the residues inside the mixing system can be cleaned from two directions without dead corners.

[0037] The return air duct 1-8 is respectively connected to the top and bottom of the mixing chamber 1-1 to balance the air flow in the mixing chamber 1-1 and the mass-breaking mechanism 2.

[0038] A discharge port is provided at the bottom of each mixing cavity, and a discharge door is provided on the discharge port. Specifically, discharge ports are respectively opened at the bottom of the mixing cavity 1-1 corresponding to the first mixing rotor assembly 1-2a and the second mixing rotor assembly 1-2b. The connecting lines between the two sides of each discharge port and the rotor center form a discharge angle α, and the discharge angle α is more than 30°.

Under the stirring action of the rotor, the discharging can also be accelerated, the discharging time is short, and the residue in the mixing mechanism 1 after discharging is extremely low.

[0040] Each discharge port is provided with a sealed discharge door 1-9; the first discharge door 1-9a and the second discharge door 1-9b are located at the bottom of the mixing cavity 1-1 and correspond to the positions of the first mixing rotor assembly 1-2a and the second mixing rotor assembly 1-2b; the inner arc surface of the discharge door 1-9 has the same arc curvature as the bottom arc of the mixing cavity 1-1.

[0042] The lump-breaking cavity 2-1 is of an inverted conical structure. Specifically, the lump-breaking cavity 2-1 has a V-shaped constriction in the axial direction. The upper size matches the interface of the mixing cavity 1-1 of the mixing mechanism 1, and the lower size matches the interface of the material leveling and dispersing cavity 3-1 of the material leveling and dispersing conveying mechanism 3. In the present invention, the lump-breaking cavity is designed as an inverted trapezoidal column structure, that is, a structure with a large upper part and a small lower part, to realize the transition between the large-volume double-rotor mixing cavity and the small-volume material leveling and dispersing cavity.

[0043] The lump-breaking rotor assembly 2-2 is located at the lower side inside the lump-breaking cavity 2-1, close to the material leveling and dispersing conveying mechanism 3. The lump-breaking rotor assembly 2-2 is vertically arranged with respect to the mixing rotor assembly, so that the mixing direction of the material in the mixing rotor assembly is completely opposite to the mixing direction of the material falling into the lump-breaking cavity in the lump-breaking rotor assembly, improving the crushing effect.

[0044] The lump-breaking rotor assembly 2-2 is provided with lump-breaking blades perpendicular to the shaft.

The material leveling and dispersing rotor assembly 3-2 consists of a third main shaft 3-21 and dispersing blades 3-22. Four groups of dispersing blades 3-22 are evenly distributed in the circumferential direction and are arranged in a spiral along the axial direction to achieve the functions of dispersing and conveying.

[0049] The material leveling and dispersing rotor assembly 3-2 is located inside the material leveling and dispersing chamber 3-1 and coincides with the axis of the barrel.

[0050] One end shaft head of the material leveling and dispersing rotor assembly 3-2 is connected to the material leveling and dispersing driving assembly 3-3; the rotation speed of the material leveling and dispersing driving assembly 3-3 is adjustable to control the discharging speed.

[0051] The material leveling and dispersing conveying mechanism 3 is provided with a discharge port 3-4 at the end along the discharging direction.

[0052] The discharge door 1-3 is in the open state during the discharging stage of the mixing mechanism 1 or when the cleaning door 1-4 is opened for cleaning. The discharge door 1-3 is in the closed state when the mixing mechanism 1 is mixing. When the mixing is completed and ready for discharging, the discharge door 1-3 is opened to discharge the agglomerated materials to the mass-breaking mechanism 2 and the material leveling and dispersing conveying mechanism 3. The discharging time can be set. After discharging is completed, the discharge door 1-3 is closed. During the discharging process, the mixing rotor assembly one 1-2a and the mixing rotor assembly two 1-2b still rotate and stir.

[0053] The present invention includes a mixing mechanism, a mass-breaking mechanism, and a material leveling and dispersing conveying mechanism, which are suitable for mixing, mass-breaking, and conveying of high-moisture materials, with good mixing uniformity, small system residue, and high production efficiency. During the production process, it is automatically and continuously produced without manual intervention, with a high degree of automation, reducing the labor intensity of workers and having a high raw material utilization rate.

[0054] Embodiment 2 High-moisture material mixing and dispersing method: The feeding sequence of raw materials such as powder, water, oil, and meat slurry is as follows: First, the powder is fed. After all the powder is fed, then water, oil and other liquids are added. During the period of adding the liquids, mixing is carried out while adding the liquids. After all the liquids are added, mixing is continued for a period of time before the meat slurry can be added. During the period of adding the meat slurry, mixing is carried out while adding the meat slurry. After all the meat slurry is added, mixing is continued for a period of time until the state of the mixed materials meets the requirements before discharging. After the discharging is completed, this batch of mixing is completed and the mixing production of the next batch can be entered. Liquids such as water and oil are atomized by nozzle pressure or assisted by compressed air atomization so that the liquids can fully contact and mix with the powder. After sufficient mixing, the meat slurry can be added to continue mixing.

[0055] As Figures 1-5 , when starting production, the cleaning doors 1-4, discharging door 1-9a of discharging door one, discharging door 1-9b of discharging door two, and the cleaning door 2-4 of the blanking hopper are all in the closed state. The material leveling and dispersion driving component 3-3 of the material leveling and dispersion conveying mechanism 3, the mass breaking driving component 2-3 of the mass breaking mechanism 2, and the mixing driving component 1-3 of the mixing mechanism 1 are started in sequence. According to the set ratio of the formula, first put the pre-mixed powder from the powder adding port 1-5, and then add a fixed amount of liquids such as grease and water from the liquid adding port 1-6. The powder and the liquid are mixed for a period of time t3 according to the set mixing time, and then a fixed amount of meat paste is added and further mixed for the set time t5. After the mixing is completed and ready to discharge, at this time, the system detects the signal of the level sensor 2-5 of the mass breaking mechanism 2. If there is no signal, it means there is no material in the mass breaking mechanism 2, and the discharging step can be entered. Open the discharging door 1-9a of the mixing mechanism 1 and the discharging door 1-9b of discharging door two. The large lumpy materials are discharged from the two discharging doors. Under the stirring action of the first rotor 1-2, the discharging is accelerated. The discharging time t6 can be set. After the discharging of the mixing mechanism 1 is completed, close the discharging door 1-9, and the mixing mechanism 1 can enter the production of the next batch. The mass breaking mechanism 2 and the material leveling and dispersion conveying mechanism 3 are connected. After the materials of the previous batch are discharged into the mass breaking mechanism 2 and the material leveling and dispersion conveying mechanism 3, the large lumpy high-moisture materials are broken into small lumps under the stirring action of the mass breaking rotor assembly 2-2 and the material leveling and dispersion rotor assembly 3-2. Part of the materials in the material leveling and dispersion cavity 3-1 are conveyed by the material leveling and dispersion rotor assembly 3-2 and discharged from the discharge port 3-4 to the downstream equipment. The materials that have not been discharged in the mass breaking cavity 2-1 and the material leveling and dispersion cavity 3-1 will be stirred and broken by the mass breaking rotor assembly 2-2 and the material leveling and dispersion rotor assembly 3-2 for many times. And during the discharging process of the material leveling and dispersion conveying mechanism 3, the materials in the mass breaking cavity 2-1 are continuously replenished into the material leveling and dispersion cavity 3-1 until all the materials in the mass breaking cavity 2-1 and the material leveling and dispersion cavity 3-1 are discharged. The rotation speed of the material leveling and dispersion driving component 3-3 of the material leveling and dispersion conveying mechanism 3 is adjustable, and the discharging amount can be flexibly controlled according to the downstream production situation.

[0056] As Figure 5 shown: Feeding time t1: Timing from the start of feeding to the end of feeding; Liquid adding time t2: Timing from the end of feeding to the completion of all liquid addition; Mixing 1 time t3: Timing from the completion of all liquid addition to the uniform mixing, generally not less than 45s, can be set; Meat paste adding time t4: Timing from the end of mixing 1 to the completion of meat paste addition; Mixing 2 time t5: Timing from the completion of meat paste addition to the uniform mixing, generally not less than 120s, can be set; When the mixing time reaches t5 and there is no signal at the lower material level, the mixing mechanism can discharge; Discharging time t6 of the mixing mechanism: It is timed from the end of mixing 2 until the set time, generally set to 20 - 30 s.

[0057] Breaking-up mechanism 2, material-uniforming, breaking-up and conveying mechanism 3 breaking-up and discharging time T: It is timed from the opening of the discharging door of the mixing mechanism 1 until there is no signal from the level sensor 2 - 5 and then delayed by t7. t7 is generally set to 10 - 20 s, that is, all the materials in the breaking-up cavity 2 - 1 and the material-uniforming and breaking-up cavity 3 - 1 are emptied to the downstream.

[0058] When the system production capacity is matched, it follows that T ≤ t1 + t2 + t3 + t4 + t5 + t6 to ensure the matching of the production capacity during the production of this mixing and breaking-up device.

[0059] After the discharging of the mixing mechanism in the previous batch is completed and the discharging door 1 - 9 of the mixing mechanism 1 is closed, the mixing mechanism can enter the production of the next batch.

[0060] When the production is over and the mixing device is cleaned, open the cleaning door 1 - 4, discharging door one 1 - 9a, discharging door two 1 - 9b and the cleaning door 2 - 4 of the feeding hopper to clean the residues inside the mixing device. After the cleaning is completed, close the cleaning door 1 - 4, discharging door one 1 - 9a, discharging door two 1 - 9b and the cleaning door 2 - 4 of the feeding hopper, and then start the material-uniforming and breaking-up driving component 3 - 3 to discharge the residual cleaning substances from the discharging port 3 - 4.

[0061] The present invention adopts a reasonable feeding sequence and mixing time setting. First, the powder materials are fed, then the liquid materials are added. After mixing, the meat slurry is added and mixing continues. The mixing uniformity is good, the system residue is small, and the production efficiency is high. During the production process, it is automatically and continuously produced without manual intervention, with a high degree of automation, reducing the labor intensity of workers and having a high raw material utilization rate.

[0062] The large discharging door of the mixing mechanism can facilitate the discharging of large agglomerated materials after mixing from the mixing mechanism. Then, through the breaking-up of the breaking-up mechanism and the material-uniforming and breaking-up conveying mechanism, small agglomerated materials are finally formed, which is convenient for the subsequent conveying and processing, and ensures the continuous and stable production of the system.

[0063] The present invention is suitable for the mixing of high-moisture materials, especially for the mixing of materials with a moisture content of more than 40%.

[0064] The above embodiments are only for explaining the technical features and concepts of the present invention. The purpose is to enable those skilled in the art who are familiar with this technology to understand the content of the present invention and implement it. It cannot be used to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit and embodiments of the present invention should be covered within the protection scope of the present invention.
