Description

Technical Field

[0001] The utility model relates to a stirring device, in particular to a stirring device for recovering agglomerated waste materials from the reaction of sulfur dioxide and pure alkali water. Background Art

[0002] After the sulfur is fully burned, the sulfur dioxide gas and the soda ash aqueous solution enter the reactor in turn for reaction and crystallization, and then the crystal material is thrown out through a centrifuge and dried through feeding and transportation. At the junction of the tail of the feeder and the drying pipeline, some crystal materials are easily accumulated due to the furnace temperature, wind force of the induced draft and other reasons. More and more accumulation will form agglomerated waste, which will affect the feeding and drying effect of the feeder. After a certain degree of accumulation, the operator needs to clean and dredge it regularly. The agglomerated waste cleaned out must be processed and recycled using a stirring device for recycling agglomerated waste.

[0003] In the prior art, the existing stirring device for recycling agglomerated waste generally puts the agglomerated waste into a stirring barrel and then puts warm water into the stirring barrel for stirring, so that the agglomerated waste is melted into a liquid with acidity, and then the liquid is transferred to a barrel containing soda ash for conversion into alkaline solution. This operation is relatively cumbersome and cannot be performed in one device. Moreover, the agglomerated waste cannot be evenly dispersed, and a lot of time is required for stirring. The recycling time is relatively long and the recycling efficiency is low. In addition, the pH of the alkaline solution prepared by recycling the agglomerated waste cannot be adjusted to a suitable range. Now, a stirring device for recycling agglomerated waste by reacting sulfur dioxide with soda ash water is urgently needed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a stirring device for recovering agglomerated waste materials from the reaction of sulfur dioxide and pure alkali water, so as to solve the problems raised in the above-mentioned background technology. The utility model has a reasonable structure, simple operation, uniform dispersion, high recovery efficiency, and can adjust the alkali solution prepared by recycling the agglomerated waste materials to a suitable pH range.

[0005] In order to achieve the above object, the utility model is realized by the following technical scheme: a stirring device for recovering agglomerated waste materials from the reaction of sulfur dioxide and soda water, comprising:

[0006] A stirring shell, a feeding hopper for adding agglomerated waste or soda ash is arranged on the top of the stirring shell, a water delivery pump for delivering warm water is arranged on the top of the stirring shell, a water inlet pipe and a water outlet pipe are arranged at both ends of the water delivery pump, the water inlet pipe and the water outlet pipe are connected to an external warm water source and the stirring shell respectively, a stirring motor is arranged at the bottom of the stirring shell, and a stirring assembly placed inside the stirring shell is arranged on the output shaft of the stirring motor;

[0008] Furthermore, the conical dispersion plate is placed directly below the feed hopper, and a rounded corner is arranged on the top of the conical dispersion plate.

[0009] Furthermore, a display screen and a PLC controller are arranged on the top of the stirring shell, a PH sensor is arranged on the side wall of the stirring shell, and the PH sensor and the display screen are respectively connected to the PLC controller.

[0011] Furthermore, a discharge pipe is provided on the side wall of the stirring shell, and a valve is provided on the side wall of the discharge pipe.

[0012] Furthermore, a transparent observation window is provided on the side wall of the stirring shell.

[0013] According to the stirring device for recycling agglomerated waste materials from the reaction of sulfur dioxide and pure alkali water of the utility model, a driving motor is operated to drive a rotating shaft to rotate, the rotating shaft drives a plurality of stirring columns to rotate, the stirring columns drive a conical dispersion plate to rotate, and then agglomerated waste materials are put into a hopper, the agglomerated waste materials are dispersed circumferentially under the action of the conical dispersion plate, and then the agglomerated waste materials are beaten under the action of the plurality of stirring columns for secondary dispersion to improve the uniformity of dispersion, and then a water pump is operated to deliver warm water in an external warm water source to the inside of a stirring shell through a water inlet pipe and a water outlet pipe, so that the liquid and the evenly dispersed agglomerated waste materials are mixed. Contact is carried out to avoid the phenomenon that the agglomerated waste is not evenly dispersed and part of it is not melted during melting, thereby accelerating the melting speed. Under the action of the stirring column, the liquid fully melts the agglomerated waste. After a certain period of time, the agglomerated waste is completely melted into liquid, and soda ash is put into the hopper. The soda ash is dispersed circumferentially under the action of the conical dispersion plate to improve the uniformity of dispersion. Then, under the action of multiple stirring columns, the evenly dispersed soda ash is fused with the liquid to form alkaline solution, completing the recovery and reuse of the agglomerated waste. The operation is simple, and the agglomerated waste and soda ash are evenly dispersed, which saves the stirring recovery time and improves the recovery efficiency.

[0014] The pH of the liquid inside the stirring shell is detected by using a pH sensor and displayed on the display screen through a PLC controller, so that the pH of the liquid can be viewed in real time, so that the liquid inside the stirring shell can be adjusted to a suitable pH range by adding alkaline solution formed by soda ash fusion.

[0025] The stirring assembly 12 includes a rotating shaft 121 which is arranged on the output shaft of the stirring motor 10 and is placed inside the stirring shell 1, a conical dispersing plate 123 for dispersing agglomerated waste or soda ash is arranged on the top of the rotating shaft 121, and a plurality of stirring columns 122 for beating and dispersing the agglomerated waste or soda ash dispersed from the conical dispersing plate 123 are evenly arranged on the side wall of the rotating shaft 121.

Warm water is delivered to the inside of the stirring shell 1 through the water inlet pipe 6 and the water outlet pipe 13, so that the liquid contacts the evenly dispersed agglomerated waste materials, avoiding the uneven dispersion of the agglomerated waste materials and the partial unmelted phenomenon during melting, thereby accelerating the melting speed. Under the action of the stirring column 122, the liquid fully melts the agglomerated waste materials. After a certain period of time, the agglomerated waste materials are completely melted into liquid, and soda ash is put into the feed hopper 4. The soda ash is dispersed circumferentially under the action of the conical dispersion plate 123 to improve the uniformity of dispersion. Then, under the action of multiple stirring columns 122, the evenly dispersed soda ash is fused with the liquid to form an alkaline solution, thereby completing the recovery and reuse of the agglomerated waste materials. The operation is simple, and the agglomerated waste materials and soda ash are evenly dispersed, thereby saving the stirring recovery time and improving the recovery efficiency.

Under the action of the mixing column 122, the liquid fully dissolves the agglomerated waste. After a certain period of time, the agglomerated waste is completely melted into liquid, and soda ash is put into the hopper 4. The soda ash is dispersed circumferentially under the action of the conical dispersion plate 123 to improve the uniformity of dispersion.
