Description

Technical Field

[0001] The invention relates to the technical field of dehydration devices for producing polyol polyethers, in particular to a pre-dehydration device for producing polyol polyethers. Background Art

[0002] In the chemical and pharmaceutical industries, polyol polyether is an important raw material, and dehydration treatment is required during its production process. In the current dehydration method, firstly, appropriate polyether polyol and dehydrating agent are selected, and the polyether polyol and dehydrating agent are mixed in a certain proportion, and the mixture is heated to a certain temperature to promote water evaporation or desorption, accelerate the dehydration process, and after the mixture is cooled, the dehydrating agent is separated from the polyether polyol by filtering or centrifugation.

[0003] The above dehydration method has the following shortcomings: when filtering, only ordinary filter discs are used, which are prone to blockage or low filtering efficiency, and need to be improved. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a pre-dehydration device for the production of polyol polyethers.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A pre-dehydration device for producing polyol polyethers comprises a device body, wherein a stirring mechanism, a heating mechanism and a filtering mechanism are sequentially arranged in the device body from top to bottom, and the filtering mechanism comprises: An annular slide rail, the annular slide rail is installed on the inner wall of the device body; An annular gear rack, wherein a plurality of slide blocks are installed on the circumferential outer wall of the annular gear rack, and the slide blocks slide in the annular slide rail; A rotation driving unit, which is installed in the device body and is used to drive the annular gear rack to rotate; An annular ramp, a connecting rod is fixed on the top of the annular ramp, the connecting rod is fixed to the outer wall of the bottom of the annular gear frame, and an inclined annular slide groove matching the shape of the annular ramp is arranged at the bottom of the annular ramp; An annular elastic membrane, the outer side of the annular elastic membrane is connected to the inner wall of the device body, and the inner side of the annular elastic membrane is connected to a filter disc; A ball head rod, the ball head rod is fixed to the outer wall of the top of the annular elastic membrane, the two ball head rods are symmetrically arranged, and the top end of the ball head rod is slidably connected to the annular slide groove of the annular ramp; The guide frame is fixed to the inner wall of the device body, and the ball head rod is slidable up and down in the guide frame. The present invention can use the filter disc for filtering by setting a filtering mechanism. The filter disc can float and work based on the rotation drive part to drive the annular gear rack to rotate, and then drive the annular ramp to rotate synchronously. Since the annular ramp is an inclined annular structure, when the annular ramp rotates, the two ball head rods achieve alternating ups and downs, thereby prompting the material to move on the top of the filter disc and promoting the filtering efficiency.

[0006] In the above technical solution, preferably, the rotation driving unit includes: A rotation drive motor is installed in the device body; The rotating driving gear, the shaft of which is drivingly connected to the output end of the rotating driving motor, is meshed with the annular gear rack.

[0007] In the above technical solution, preferably, a plurality of equidistant and concentric annular ribs are arranged on the top of the annular elastic membrane. By providing the annular ribs, the material can generate a certain degree of up and down vibration when moving on the top of the filter plate, and a certain degree of blocking and deceleration can be performed, so that water can pass through the filter holes faster, thereby improving the filtering efficiency of the filter plate.

[0008] In the above technical solution, preferably, a second support frame is fixed in the main body of the device, and a hammer assembly for hammering the filter disc is arranged on the second support frame. The hammer assembly can hammer up the material on the filter disc to prevent the material from clogging the filter disc, thereby accelerating the water to pass through the filter holes and improving the filtering efficiency of the filter disc.

[0010] The adoption of this structure makes it possible to eliminate the need for additional power for the hammering assembly. In the process of driving the ball head rod to move up and down by the driving force of the rotating driving part, the first lever and the second lever move up and down. The first lever and the second lever cooperate with the first inclined surface and the second inclined surface respectively to push the sliding block to move back and forth. In the process of the reciprocating movement of the sliding block, the guide block first moves along the horizontal groove across the one-way gear assembly. When the guide block moves to another one-way gear assembly, it is guided to move along the inclined groove. In the process of the guide block moving down along the inclined groove, the ball head push rod moves down and the spring is compressed. When the guide block moves to the bottom of the vertical groove, the spring quickly bounces up and the guide block quickly resets along the vertical groove, thereby achieving the purpose of the ball head push rod hammering the filter disc.

[0011] In the above technical solution, preferably, the one-way gear assembly includes a hinge plate arranged at the top of the intersection of the inclined slot and the transverse slot, and a torsion spring is arranged on the hinge shaft of the hinge plate to make the hinge plate elastically fit the outer side wall of the top of the inclined slot.
