Abstract
The utility model discloses a sand feeding device of a cold-box core blower. The device comprises a sand feeding hopper and a sand feeding passage connected with the sand feeding hopper, wherein a butterfly valve is mounted in the sand feeding passage. The butterfly valve is used in the sanding feeding device to take the place of a slide plate driven by an air cylinder in the prior art, thereby effectively avoiding the problems such as frequent jamming of the slide plate during sand feeding which further causes the shutdown of equipment, facilitating the production of users and achieving positive effects.
Description
Technical field
The utility model relates to a kind of sanding device that is used as cold-box core blower in the foundry machinery.
Background technology
Cold-box core blower often will use various sands as a kind of coremaking equipment main in the foundry machinery, the operation that adds sand in the prior art generally moves reciprocatingly by the flashboard that is driven by cylinder and realizes, because in the middle of flashboard, be provided with the hole, thereby when moving to the sand hopper bottom in the position in hole, sand just flows out from sand hopper, reaches the purpose that adds sand.
But such operation format causes flashboard stuck through regular meeting owing to the damage of flashboard sealing ring when reality is used, thereby perhaps sand accumulates in and causes stuck or the like the situation of flashboard to take place up and down between the cover plate, until causing device damage or shutdown maintenance.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of can avoid adding sand passage appearance obstruction or sanding device smooth, that keep adding the unimpeded cold-box core blower of sand passage when adding sand.
Its technical problem to be solved can be implemented by the following technical programs.
A kind of sanding device of cold-box core blower comprises following sand sand hopper and the following sand passage that is connected with following sand sand hopper, is being provided with a butterfly valve in the sand passage down.
As one of preferred embodiment of the technical program, described butterfly valve is arranged on down between the sand hopper and following sand mouth in the sand passage.
Wherein, described butterfly valve can be the flange form butterfly valve.
Also, on the valve rod of described butterfly valve, can add worm reducer as the further improvement of the technical program.
Adopt the cold-box core blower sanding device of this technical scheme; the flashboard of selecting to substitute cylinder drive in the prior art for use by butterfly valve; efficiently solve the stuck generation that causes problems such as equipment downtime of easy flashboard when adding sand, help user's production, brought positive effect.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model being done one describes in detail.
Fig. 1 is a structural representation of the present utility model;
---sand hopper 2---butterfly valve 3---adds the sand mouth among the figure: 1
The specific embodiment
Cold-box core blower sanding device as shown in Figure 1 is connected to sand passage down in storing sand hopper 1 lower end, wherein on the following sand passage that adds between sand mouth 3 and the sand hopper 1, is provided with butterfly valve 2.
Wherein this butterfly valve 2 is preferably selected the flange form butterfly valve for use.Simultaneously on the valve rod of described butterfly valve, can add worm reducer.Because adopt worm reducer not only can make butterfly plate have self-lock ability, butterfly plate is stopped on the optional position, can also improve the operating characteristics of valve.
Because adopt butterfly valve to replace having brought the switching time short behind the gate valve, operational torque is little, the little and lightweight advantage of installing space.
On the related sanding device of the utility model, replace original cylinder to drive the mode of flashboard with butterfly valve, the folding ratio of butterfly valve is easier to, and has cancelled the structure of flashboard, just can not seal the bad problem that causes flashboard to be stuck because of flashboard.Make to add the sand convenience and be not easy damage, reduce maintenance time.
