Description

A three-control dust collection plus coagulant screening device

technical field

The utility model belongs to the field of gypsum board production, and in particular relates to a three-control dust collection device equipped with coagulation accelerator screening device.

Background technique

In order to shorten the setting time of the gypsum board, dihydrate gypsum is generally used as a coagulant in the production line to shorten the setting time and increase the production speed.

At present, the coagulant used in the production line generally needs to be purchased from a manufacturer specializing in the preparation of the coagulant or purchased from the market. The cost is relatively high, and it also increases the production cost of gypsum board. Or it is necessary to use gypsum board raw materials for self-preparation, and when a certain amount of labor is required in this process, the production cost of gypsum board is also increased.

Utility model content

The purpose of the utility model is to provide a three-control dust collection device with coagulation accelerator screening device, which can solve the above problems.

In order to achieve the above object, the concrete technical scheme of the utility model is as follows:

A three-control dust collection and coagulant screening device, including a gypsum board three-control system dust collection lower barrel, a crushing device, and a vibrating screen;

The pulverizing device includes a collection port, a pulverization part and a discharge port, the collection port is arranged above the pulverization part, the discharge port is arranged at one end of the pulverization part, and the collection port The included angle between the axis and the axis of the outlet is greater than or equal to 90°;

The material collecting port in the pulverizing device is located directly below the material discharging port of the dust collecting lower material cylinder, the vibrating screen is located directly below the discharge port, and a material receiving trough is arranged below the vibrating screen.

Further, the crushing device is a cylindrical "L-shaped" bell mouth structure, the material collecting port is located at the end with the bell mouth, and the end with a larger diameter is located at the outermost end, and the discharge port is located at the other end, The crushing part is located in the middle, and a spiral reamer is arranged in it.

The utility model provides a three-control dust collecting device with coagulant accelerator screening device, which recovers and screens the raw gypsum produced in the production of the three-control system, and then obtains the coagulant dihydrate required in the production of gypsum boards. Gypsum powder, which can not only make effective use of waste recycling, but also save costs. Moreover, by installing a recovery and screening device under the dust collecting lower barrel, the produced raw gypsum can be crushed and screened into the required dihydrate gypsum powder at one time, which can be used as a coagulant, which not only reduces the impact of the produced massive raw gypsum on the production environment. It also saves the labor cost of retransportation, storage and reprocessing, obtains effective products at one time, and saves the production cost of gypsum board.

detailed description

Embodiments of the present utility model are described below in conjunction with accompanying drawings.

As shown in Figure 1, a three-control dust collection and coagulant screening device is installed, including a gypsum board three-control system dust collection lower barrel, a crushing device, and a vibrating screen;

The pulverizing device includes a collection port, a pulverization part and a discharge port, the collection port is arranged above the pulverization part, the discharge port is arranged at one end of the pulverization part, and the collection port The included angle between the axis and the axis of the outlet is greater than or equal to 90°.

Taking the positive direction of the x-axis as the coordinate, the reverse angle is preferably greater than 90°. At this time, the cabin of the crushing part is inclined downward along the negative direction of the x-axis and the discharge port, which is conducive to the aggregation of the crushed particles At the same time, it is also conducive to the material removal speed of the crushing device, so that the material will not be accumulated at the collection port or the crushing part.

The material collecting port in the pulverizing device is located directly below the material discharging port of the dust collecting lower material cylinder, the vibrating screen is located directly below the discharge port, and a material receiving trough is arranged below the vibrating screen.

Preferably, the crushing device is a cylindrical "L-shaped" bell mouth structure, the collecting port is located at one end with the bell mouth, and the end with a larger diameter is located at the outermost end, and the discharge port is located at the other end, so The crushing part is located in the middle, and a spiral reamer is arranged inside.

The extension direction of the axis of the spiral reamer is consistent with the axis direction of the discharge port. The external motor drives the spiral reamer to rotate, and the large pieces of gypsum or large particles of gypsum are crushed into powder, and then enter the vibrating screen through the discharge port. , and finally screen out the required dihydrate gypsum powder as the coagulant required in the production of gypsum boards.

As mentioned above, although some embodiment of this invention was demonstrated, these embodiment is presented as an example, and is not intended to limit the range of this invention. These new embodiments can be implemented in other various forms, and various omissions, substitutions, and changes can be made without departing from the gist of the present invention. These embodiments and modifications thereof are included in the scope and gist of the present invention, and are also included in the invention described in the claims and their equivalent ranges.
