Description

Technical Field

[0001] The utility model relates to the technical field of regeneration devices, in particular to a device for improving the regeneration performance of ester-hardened water glass sand. Background Art

[0002] During the use or storage of water glass sand, the condensation reaction and depolymerization reaction of polysilicic acid occur simultaneously, which will cause the bonding strength of the sand to decrease, that is, aging occurs.

[0003] The aging of water glass sand will form an inert film on the surface of the sand, which will affect the normal use of the sand. For this reason, the sand needs to be regenerated. The current regeneration method usually uses centrifugal collision to regenerate the sand. During the regeneration process, on the one hand, the dust generated will pollute the air. On the other hand, the regeneration only relies on friction and collision, and the regeneration performance of the sand is poor.

[0004] Therefore, we propose a device to improve the regeneration performance of ester-hardened water glass sand to solve the existing problems. Utility Model Content

[0005] The utility model aims to solve the problems existing in the background technology and to provide a device for improving the regeneration performance of ester-hardened water glass sand.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for improving the regeneration performance of ester-hardened water glass sand, comprising a chassis, a tank body, a positioning plate and a sand blasting disc, the upper surface of the chassis is installed with the tank body, the lower end of the inner wall of the tank body is installed with a positioning plate, the lower surface of the sand blasting disc is installed with a shaft cylinder at the axial position, the shaft cylinder is rotatably installed on the positioning plate, the upper surface of the sand blasting disc is designed to be concave in the center of a circle, the lower surface of the positioning plate is equidistantly installed with various electric heating parts, a top cover is installed at the top opening of the tank body, a feed pipe is provided at the eccentric position of the top cover, and a suction pipe is provided at the axial center of the top cover.

[0007] Preferably, a sand retaining ring is installed on the upper end of the inner wall of the tank body, and the sand retaining ring is in rotational contact with the sand throwing disc.

[0008] Preferably, a motor structure is embedded and installed inside the positioning plate, and a gear is provided at the output end of the motor;

[0009] A gear ring is installed on the outer wall of the bottom end of the shaft cylinder through bolts, and the gear ring is in a gear-meshing state with the gear.

[0010] Preferably, a discharge port is provided at the bottom end of the tank body, and a sealing cover is threadedly mounted on the outer opening end of the discharge port.

[0011] Preferably, a support seat is installed on the lower surface of the chassis;

[0012] There are four support seats in total, and the positions of the four support seats are distributed in a ring array on the lower surface of the chassis.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] During the use of the utility model, the old ester hardened water glass sand enters the tank body through the feed pipe, and the old sand falls to the eccentric position of the sand throwing plate. At this time, the sand throwing plate rotates under the drive of the power structure, and the sand performs radial acceleration motion under the action of centrifugal force. The thrown sand collides and rubs with the wear-resistant sand retaining ring and the sand grains, so that the inert film on the surface of the sand grains is broken and falls off.

[0015] At the same time, the suction pipe is connected to the external pump suction structure, and the micro powder generated in this process is discharged through the suction pipe to achieve the regeneration effect;

[0016] Furthermore, after a certain period of centrifugal treatment, the sand throwing disc is controlled to stop rotating, and the sand loses the centrifugal effect and finally falls to the lower part of the tank through the shaft cylinder under the action of gravity. At this time, the electric heating element is controlled to work to provide energy to the sand, so as to promote the re-depolymerization of the highly polymerized polysilicic acid colloid particles remaining on the surface of the sand, further eliminating the aging phenomenon of the sand, and the regenerated ester-hardened water glass sand is finally discharged through the discharge port;

[0017] The utility model can effectively treat the associated fine dust while regenerating the sand by means of centrifugal rotation collision, thereby ensuring that the air and environment of the workplace are not polluted, and at the same time, cooperates with the heating method to eliminate the residual aging of the sand surface and improve the regeneration performance of the sand.
