Disclosure of utility model

(One) solving the technical problems

Aiming at the defects of the prior art, the utility model provides the double-feed-port stirring and mixing equipment, which solves the problems that the prior equipment cannot feed, stir and discharge simultaneously, has low production efficiency and is not cleaned cleanly.

In the conventional stirring apparatus, all materials are usually added into a stirring tank, then fully stirred, and after stirring, the stirred materials are discharged (after each discharge, the materials are required to be cleaned again, then re-fed and stirred), so that the production efficiency is affected due to the fact that the materials cannot be simultaneously stirred, and b, after a period of production, in order to avoid the influence on the quality of the products caused by attachments on the stirring tank, the materials on the inner wall of the stirring tank are cleaned after the production is usually carried out for several times, in the conventional method, a cover of the stirring tank is directly opened, and then the inner wall of the stirring tank is cleaned by using a high-pressure water pipe and a water spray nozzle, so that the cleaning is possibly not clean enough (because the water spray nozzle is positioned at a certain distance from the inner wall of the lower part of the stirring tank, the impact force of cleaning water is not enough; many chemical factories currently adopt the method).

The stirring and discharging device has the advantages that feeding, stirring and discharging can be simultaneously carried out (production efficiency is improved), when the fed materials flow from the position A to the position B, stirring is carried out just after the fed materials flow to the position B (the difficulty is how to ensure the stirring effect), and the inner wall of the stirring long box can be cleaned when the subsequent cleaning is needed.

For ease of understanding, the principles of the present solution and core design points are described:

1. A working process;

a. By adding corresponding materials into conical bins of different feeding assemblies, the auger shafts feed the materials into the discharge pipe and discharge the materials, the materials falling from the discharge pipe just fall at the front ends of the auger shafts A, and the upper parts of the two auger shafts A gradually approach to rotate so as to enable the materials to be extruded into a gap between the two auger shafts A (which is beneficial to mixing the materials); stirring is carried out under the action of stirring blades A of a material auger shaft A, and the materials flow from the front end to the rear end of the auger shaft under the action of the stirring blades A (the stirring blades A are provided with intervals, the materials are not acted on by the stirring blades A all the time in sequence, the flowing speed of the materials can be slowed down, the full stirring is facilitated, good stirring can be realized as long as the length of a long stirring box is long enough), even stirring is finished when the materials flow to the rear end, and then the stirred materials are discharged through a discharge hole;

2. The feeding component is internally provided with a horizontal guide pipe and a corresponding auger shaft B;

If the liquid material (the material in the scheme) is added into the feeding component, a certain pressure is generated through the auger shaft B, and the liquid material can be injected below the liquid level in the stirring long box, so that the liquid material can be better acted by the auger A (if the auger shaft B is not pressurized, the liquid material is injected into the liquid level by gravity only, and the depth of the liquid material injected into the liquid level is relatively high);

Of course, this structure is also beneficial to the feeding of powder materials, if the powder materials (which is not the material of this scheme, only the expansion scheme is also within the scope of the application), because the guiding tube is horizontally arranged, when the auger shaft B does not rotate, the feeding will be stopped (here, the powder materials can be added with additional water through the cleaning component if stirring is performed in the stirring long box), which is beneficial to controlling the feeding amount (the existing method is mostly that the feeding is controlled by opening and closing the door, the opening and closing of the door is one process, any material leaks down in the closing process of the opening and closing of the door, and the horizontally arranged guiding tube has the advantage that when the auger shaft B stops, the feeding can be stopped immediately);

3. In addition, when different materials are initially added, the materials flow to a gap between two auger shafts to complete initial good mixing, and then the time of the materials in the stirring long box is prolonged by the length of the stirring long box and the interval arrangement of the stirring blades A on the stirring shaft A so as to improve the stirring effect;

4. Through stretching into the long incasement of stirring with cleaning assembly, reduced shower nozzle and the long incasement wall distance of stirring to all have the water pump to carry out the pressure boost in every cleaning assembly, still through the shower nozzle of different orientations, increase cleaning performance (traditional cleaning method, be through the direct washing of high-pressure water pipe, but this scheme is the long case of stirring, can't wash with the high-pressure water pipe).

In summary, the utility model has the technical effects and advantages that:

1. The material feeding, stirring and discharging can be simultaneously carried out, when the material is added at the front end of the auger shaft A, the material is conveyed to the rear end under the action of the auger shaft A, and the stirring and discharging are finished at the rear end of the auger shaft B;

In addition, by increasing the length of the stirring long box and arranging the stirring blades A on the stirring shaft A at intervals, the residence time of the materials in the stirring long box is increased, and the materials can be fully and uniformly stirred;

2. In the cleaning assembly, the distance between the corresponding spray head and the stirring long box is small (each assembly is provided with a water pump and the inner wall of the spray head at different positions towards the stirring water tank), and the cleaning effect is good (the traditional method is that the high-pressure water gun is adopted for direct flushing, and the flushing effect is not ideal).
