The production and processing cost is reduced.

Description

Technical Field

[0001] This utility model relates to the field of quicklime screening technology, specifically a screening device for quicklime production line. Background Technology

[0002] Quicklime is made from slaked lime. After being made and dried, quicklime is usually in the form of lumps mixed with powder. It is then ground into powder in a grinding equipment and bagged. However, in the current workshop, the powder in the lumps is screened out before the quicklime enters the grinding equipment. This method is equivalent to adding an extra processing step, which reduces the overall work efficiency and increases labor and other costs.

[0003] Therefore, in order to correct the above-mentioned defects, we propose a screening device for quicklime production line. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a screening device for a quicklime production line.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screening device for a quicklime production line, comprising a filter screen, the filter screen being arranged in a single line and equipped with a spiral propeller, a suspension rod being provided above the filter screen, an expansion bolt being provided at the top of the suspension rod, and a material receiving support being installed at the bottom of the filter screen.

[0006] Furthermore, the filter screen is equipped with a protective cover, and the suspension rod is fixed to the protective cover by screws. A feed hopper is provided on the protective cover.

[0007] Furthermore, a funnel-shaped material collection hood is installed at the bottom of the receiving tray, and a guide pipe is connected to the outlet of the funnel-shaped material collection hood.

[0008] Furthermore, the filter screen has a plate-like structure.

[0009] Furthermore, the filter screen has a cylindrical structure and a feed inlet is provided on the filter screen, which is connected to the feed hopper.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the screening device in this utility model is connected between the drying equipment and the grinding equipment. It serves as both a screening device and a conveying device. That is, it directly screens out the powder from the lumps during the process of feeding quicklime into the grinding equipment. Compared with the current workshop technology, it eliminates one process, which can improve work efficiency and reduce production and processing costs. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides a technical solution:

[0018] Please see Figure 1-3 A screening device for a quicklime production line includes a filter screen 1, which is arranged in a single line and equipped with a screw propeller 8. A suspension rod 4 is provided above the filter screen 1, and an expansion bolt is provided at the top of the suspension rod 4. A material receiving tray 7 is installed at the bottom of the filter screen 1.

[0019] The entire screening equipment is suspended and installed at the discharge port of the drying equipment or between the feeding equipment and the grinding equipment by the suspension rod 4. Lump lime mixed with powder enters the filter screen 1 from the feed hopper 6, and then the lime is pushed forward by the screw propeller 8. During the forward movement, the screw of the screw propeller 8 drives the lime to stir, which will cause the powder to separate out. The screw also contacts the filter screen 1. When the screw moves, it will cause the filter screen 1 to shake, which will speed up the screening and filtration.

[0020] The filter screen 1 is equipped with a protective cover 2, and the suspension rod 4 is fixed to the protective cover 2 by screws. The two sides of the filter screen 1 are fixed to the protective cover 2. The protective cover 2 is to prevent powder from floating upwards.

[0021] The powder coming down from the filter screen 1 enters the funnel-type collecting hood 3. The bottom of the receiving tray 7 is connected to the funnel-type collecting hood 3. The outlet of the funnel-type collecting hood 3 is connected to the guide pipe 5, and the powder enters the packaging bag through the guide pipe 5.

[0022] In the above, the filter screen 1 has a plate-like structure or a cylindrical structure, and the filter screen 1 is provided with a feed inlet 9, which is connected to the feed hopper 6.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
