Description

Rubbing regener

The present application claims priority to Chinese Patent Application No. 2016104812765 (Application Date: June 27, 2016; Title of Invention: Sweep Recycling Machine), the entire contents of which are incorporated herein by reference.

Technical field

The invention relates to the technical field of sand casting regeneration equipment, in particular to a scrub-type recycling machine.

Background technique

Casting is the foundation of the entire industry. Casting is a basic component of industrial equipment. Sand casting is the most common process in various casting processes, among which self-hardening sand (various resin sand, water glass sand, etc.) ) account for the vast majority of them. Since sand is now a scarce resource and the state has already controlled the exploitation of sea sand, the recycling of sand in the foundry industry is very important.

The recycling machine is one of the most critical equipment in the recycling process of sand. At present, a regenerator commonly used in China is called a centrifugal regenerator, which belongs to the technology of the 1970s. The regenerator that produces 10 tons/hour needs to be equipped with a 30kw motor, which consumes a lot of energy; and the regeneration method is soft. Regeneration, the sand is pulled out by the wear-resistant disc, bounces back after hitting the retaining ring, and then collides with the sand that has been rubbed to rub it to achieve the purpose of reclaiming the film. The structure is complicated, the wearing parts are more, and the replacement is more troublesome. .

Summary of the invention

The object of the present invention is to provide a squeegee type regenerative machine for solving the problems of complicated structure, high energy consumption and large wearing parts of the regenerative machine in the prior art.

The invention provides a squeegee type regenerative machine, comprising a motor, a main shaft, a mounting plate and a fixed plate and a movable plate disposed opposite to each other, wherein the mounting plate is disposed above the fixed plate, and the main shaft is axially disposed on the movable plate. A bearing housing is arranged outside the main shaft, and a belt pulley is arranged at the bottom of the bearing housing, and the motor and the belt pulley are connected by a belt.

Further, a gap adjustment module is further included, and the gap adjustment module is disposed at two ends of the mounting board.

Further, a feed funnel is further included, and the feed funnel is disposed above the mounting plate.

Further, the fixing plate is further provided with a hole penetrating the feeding funnel.

Further, the belt adopts a V-belt.

Further, the fixed plate and the movable plate are made of wear-resistant castings.

The utility model has the advantages of simple structure and less wearing parts, and the two grinding discs and the sand are contacted by the fixing plate and the moving plate, and the power consumption is small, and the grinding disc gap can be adjusted to meet the regeneration requirements of different sands. The regeneration effect is good; the 10 ton/hour regenerator only needs 11kW motor, which can save more than 60% energy compared with the centrifugal regenerator.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments.

The embodiment of the invention discloses a squeegee type regenerative machine, as shown in FIG. 1 and FIG. 2, comprising a motor 1, a main shaft 2, a mounting plate 3, and a fixed plate 4 and a movable plate 5 disposed opposite each other, wherein the mounting plate 3 is disposed above the fixed plate 4, the spindle 2 is axially disposed on the movable plate 5, and the bearing housing 6 is disposed outside the main shaft 2. The bottom of the bearing housing 6 is provided with a belt pulley 7, and the motor 1 and the belt pulley 7 pass through the belt. 8 connection, in particular, the belt 3 can be realized by a V-belt, and the fixing plate 4 and the moving plate 5 can be realized by wear-resistant castings.

In the embodiment of the present invention, the squeegee regenerative machine may further include a gap adjustment module 9 disposed at two ends of the mounting plate 3, and is mainly used for adjusting a gap between the fixed plate 4 and the movable plate 5, Thereby meeting the regeneration requirements of different coarse sands. Specifically, the gap adjustment module 9 may include a support post 91 axially disposed at two ends of the mounting plate 3, and a spring 92 sleeved on the support post 91 and connected to the mounting plate 3, thereby adjusting the length of the adjusting spring. The gap between the disk 4 and the moving plate 5.

In the present embodiment, a feed funnel 10 is further included, and the feed funnel 10 is disposed above the mounting plate 3, on the fixed plate 4 A hole penetrating the feed funnel 10 is also provided so that sand can be fed from the feed funnel 10 and passed between the movable plate and the fixed plate through a hole in the platen 4 that penetrates the feed funnel 10. Cavity.

The following is a further description of the squeegee type regenerative machine of the present invention. In the present embodiment, the sand is added from the uppermost feeding funnel, and enters the cavity between the movable plate and the fixed plate through the hole in the middle of the fixed plate; The motor drives the rotating plate mounted on the main shaft through the V-belt; the mutual movement between the moving plate and the fixed plate causes the sand to rub between the two plates. Since there is a certain gap between the two plates, the sand will not be Grinding only removes the film of the binder such as resin on the surface of the sand to achieve the purpose of regeneration.

The rubbing type regenerative machine of the invention has the advantages of simple structure and less wearing parts, and the two grinding discs and the sand are contacted by the fixed disc and the movable disc, and the power consumption is small, and the grinding disc gap can be adjusted to meet the regeneration requirements of different sands, and the regeneration effect thereof. Good; the 10 ton/hour regenerator only needs 11kW motor, which can save more than 60% energy compared to the centrifugal regenerator.

Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, and are not intended to be limiting; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that The technical solutions described in the foregoing embodiments may be modified, or some or all of the technical features may be equivalently replaced; and the modifications or substitutions do not deviate from the technical solutions of the embodiments of the present invention. range.
