Background
The polyacrylamide as the macromolecular flocculating solvent is an essential medicament in the sludge dewatering process, but needs to be dissolved firstly before use, the subsequent sludge dewatering treatment effect can be directly influenced by the quality of the dissolved medicament, but the molecular structure of the polyacrylamide determines that the polyacrylamide is difficult to dissolve and cannot be stirred at a high speed, so that the research and development of a medicament dissolving and adding device with an optimized structure is very important.
The prior patent (application number: CN 201320797007.1) discloses a polyacrylamide rapid dissolving device, belonging to the technical field of sewage treatment agents. The method aims to solve the problems of low utilization efficiency of polyacrylamide, severe production environment and slow dissolution time of polyacrylamide in the traditional sewage treatment process. The reaction dissolving device comprises a hollow tank body, a stirring device and a heating device. The dissolving device is simple in structure and convenient to operate. The utility model discloses an improve the shortcoming of traditional dissolving method, improved work efficiency and economic value. However, the device disclosed by the patent still adopts a mode of stirring and dissolving by installing a stirring device in the tank body, and cannot solve the problem that the dissolution of the stirring medicament is not complete due to a back mixing area generated above the stirring blade.
Disclosure of Invention
The utility model aims at providing a sludge dewatering agent adding device which has simple structure, energy consumption saving and even stirring aiming at the defects of the prior device.
The device is implemented in the concrete way, a sludge dewatering medicament adding device, including agitator tank, water heating device, add the medicine fill, go out the pencil, the agitator tank is the cylinder tube-shape, a top cap is installed at the top, install water heating device and add the medicine fill on the top cap, water heating device and add the medicine fill and all insert in the agitator tank through the pipeline, a speed governing rotating device is installed to top cap central point, the speed governing rotating device is connected with the one end of a pivot, the pivot other end passes in the top cap inserts the jar, the pivot end-to-end has the leaf oar, there is a pencil to connect out agitator tank bottom, go out to install suction pump and valve on the pencil respectively.
The polyacrylamide dehydration medicament is mixed with warm water heated by the water heating device in the stirring tank through the medicament feeding hopper, then the speed-regulating rotating device is started to mix and stir the mixture for 30 minutes, the mixture is stopped, and finally the valve is opened and the suction pump is started to add the mixed medicament into the dehydrator to be mixed with the sludge.
Furthermore, a heat insulation sleeve is wrapped outside the tank body of the stirring tank, so that the temperature of the stirring agent solution is ensured to be between 30 and 40 ℃, and the agent is convenient to dissolve.
Furthermore, 2 vertical partition plates extending to the bottom of the stirring tank are arranged on the bottom surface of the top cover, and gaps are formed between the edges of the vertical surfaces of the partition plates and the edges of the side walls in the tank body, so that the adhesion of the medicament in the stirring process can be reduced.
Furthermore, the number of the blades is 3 or 5, and the length of each blade is two fifths of the horizontal circular section radius of the stirring tank.
Furthermore, the vertical distance between the blade paddle and the bottom surface of the stirring tank is one fourth to one third of the height of the stirring tank, so that the axial stirring strength of the bottom of the tank body can be reduced, and the degradation phenomenon caused by the breakage of a medicament molecular chain is reduced.
Further, the speed regulating rotating device can regulate the rotating speed of the rotating shaft, and the rotating speed is controlled at 250-300 r/min.
The utility model has the advantages that:
1. utilize and set up the back mixing phenomenon that vertical baffle appears in order to reduce the stirring process in the agitator tank, ensure that dehydration medicament misce bene.
2. Warm water is added by a heating device to be stirred with the medicament, so that the dissolving time of the dehydrated medicament is shortened.
3. The stirring tank and the stirring blade structure are optimally designed, and the stirring and dissolving effects of the dehydration medicament are improved.
