Background

In the process of producing cellulose ether, it is not strictly ensured that the process parameters are completely consistent in each batch of production, however, the fluctuation of the process parameters causes the variation of various properties of materials, that is, the products of each batch have some differences in properties. In order to reduce the impact of these variations on quality and thus to obtain a uniform mixture that is representative of the average properties of the product, it is often necessary to blend and homogenize different batches of material during the post-treatment process.

There is currently no special mixer for use in cellulose ether production, and conventional universal mixers are not suitable for cellulose ether production in terms of charging and mixing methods. Traditional blendor tail open-type is not good to the powdered granular cellulose ether environment-friendly.

Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

The utility model relates to a pulse spiral belt type mixer for producing cellulose ether, which is applied to the production of cellulose ether and is used for mixing powdery materials. The main conception of the utility model is to combine the pulse bag type dust collector with a spiral mixer. The material filling is carried out by using a pulse bag type dust collector, and the material mixing is carried out by using a spiral mixer.

As shown in fig. 1 and 2, the mixer comprises a mixing bin 1 and a pulse bag type dust collector 2, wherein the pulse bag type dust collector 2 is arranged at the upper end of the mixing bin 1. The inlet of the pulse bag type dust collector 2 is communicated with a material source through a ventilation pipeline, and the pulse bag type dust collector 2 is used for uniformly adding materials into the mixing bin 1. The pulse bag type dust collector 2 sucks the material from the source. Since the material is a powder, it is understood that it is in the form of dust, which is entrained in the air stream and carried forward by the air stream.

A spiral mixer is arranged in the mixing bin 1 and is used for stirring materials, so that the materials are uniform. As shown in fig. 2, the screw mixer includes a motor 3 and a screw stirring device driven by the motor 3. Further, the spiral stirring device comprises a rotating shaft 4, a supporting rod 5 and an arc stirring belt 6. The supporting rod 5 is vertically fixed on the surface of the rotating shaft 4. The supporting rod 5 is used for supporting and installing the arc stirring belt 6. The arc stirring belt 6 extends to the rotating shaft 4 from the top end of the supporting rod 5 in an arc shape, the top end of the arc stirring belt 6 is fixedly connected with the supporting rod 5, and the other end of the arc stirring belt is fixedly connected with the rotating shaft 4. The arc stirring belt 6 can stir the materials at the position close to the center and the position far from the outer layer of the center relative to the rotating shaft 4.

In a specific implementation, the curved stirring belt 6 is preferably arranged in a symmetrical curve shape similar to a sine or cosine function, and the arc top of the curve is located at the top end of the support bar 5. As particularly shown in fig. 2. The arc stirring belt is in a blade shape.

A discharge hole 7 is arranged on the lower end surface of the mixing bin 1 and is used for discharging the stirred materials. A plurality of discharge ports 7 may be generally provided as needed. The arc stirring belt 6 discharges materials in the rotation stirring process, which is more beneficial to the falling of materials.

In a specific implementation of the utility model, the stirring speed of the spiral stirring device is not required to be too high, so that the spiral stirring device is required to be provided with a speed reducer, specifically, the rotating shaft 4 of the spiral stirring device is in power connection with the speed reducer through a coupler, and the speed reducer is in power connection with the motor 3, so that the speed reduction is realized.

When in use, the utility model is mainly used as post-processing equipment for cellulose ether production. The pulse bag type dust collector is sucked by negative pressure according to the working pressure. The powdered material is blown by a fan and is wrapped by wind to flow, and negative pressure is generated by a pulse bag type dust collection device, so that the shell adopts a closed structure. The material-containing air flow flows from the outer side to the inner side of the filter bag, the material is filtered and trapped by the outer side of the filter bag, and when the material on the surface of the filter bag is continuously increased, the resistance of the equipment is increased to a set value, and a control system outputs a signal. The pulse valves are opened one by one, so that compressed air is blown to clean the filter bags through the nozzles, the filter bags are suddenly expanded, and dust attached to the surfaces of the filter bags is quickly separated from the filter bags under the action of reverse air flow and falls into the lower spiral belt mixer. The blowing only cleans the filter bags row by row, other rows of filter bags which are not blown are still normally filtered, the blower is not stopped, and clean gas is discharged into the atmosphere by the blower. The pulse bag type dust collector is purchased and used, and the pulse bag type dust collector is purchased according to the actual situation and meets the specification.

One end of the spiral belt type mixer is provided with a speed reducer with a large speed ratio, the speed reducer is connected with a rotating shaft through a coupler, a plurality of supporting rods are fixed on the rotating shaft, and each supporting rod is provided with an arc stirring belt. The arc stirring belt can collect outer materials from two sides to the center, and can also convey the materials from the center to two sides, so that the materials can form more vortex in flowing, the mixing speed is increased, and the mixing uniformity is improved.

The above embodiments are merely illustrative of the preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model, and various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model should fall within the protection scope defined by the claims of the present utility model without departing from the design spirit of the present utility model.
