Abstract

The utility model discloses a screening device for a feeding hopper. The screening device for a feeding hopper comprises: a hopper body, and a screen mesh is arranged at an opening above the hopper body. The feeding hopper screening device of the utility model is provided with a screen at the feeding port of the feeding hopper, and the material is screened once while feeding, which provides convenience for the follow-up work and improves the work efficiency of the follow-up work.

Description

Loading hopper screening device

technical field

The utility model relates to the field of cement auxiliary material manufacturing devices, in particular to a feeding hopper screening device.

Background technique

The hopper is a funnel-shaped feeding container installed above other working machines, with an opening above it, and materials are introduced from the opening and enter subsequent machines for processing.

Since the hopper does not have a screening function, all materials enter the machine through the hopper, including some large pieces of materials, which need to be screened by the screening machine again in the follow-up work, which wastes energy and has low work efficiency.

Contents of the invention

The purpose of the utility model is to provide a feeding hopper screening device for screening materials when feeding.

In order to achieve the above purpose, the feeding hopper screening device provided by the utility model comprises: a hopper body, and a screen is provided at the upper opening of the hopper body.

In some embodiments, the screen is a bar screen.

In some embodiments, the screen includes a screen frame, a plurality of sieve plates, and a plurality of support rods corresponding to the sieve plates, the plurality of support rods are arranged in parallel in the screen frame, and the two ends of the support rods are respectively connected On two opposite sides of the sieve frame, each sieve plate is respectively fixed on each support rod through connecting support grooves, each sieve plate is parallel to each other, and the sieve plate intersects with the horizontal plane.

The feeding hopper screening device of the utility model is provided with a bar screen at the feeding port of the feeding hopper, and the material is screened at the same time of feeding, which provides convenience for follow-up work, saves energy, and improves follow-up work. At the same time, the screen adopts bar screen, which is not easy to block holes and improves the efficiency of screening.

Description of drawings

Fig. 1 is the structural representation of the feeding hopper screening device of a kind of embodiment of the present utility model;

Fig. 2 is a structural schematic diagram of the screen mesh of the feeding hopper screening device shown in Fig. 1 .

Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Figure 1 and Figure 2 schematically show a screening device for a feeding hopper according to an embodiment of the present invention.

As shown in FIG. 1 , the hopper screening device of the present invention includes: a hopper body 10 and a screen 20 at the upper opening of the hopper body 10 .

In this embodiment of the utility model, the screen 20 adopts a bar screen.

As shown in FIG. 2 , the bar screen 20 includes a screen frame 201 , a plurality of sieve plates 202 , and a plurality of support rods 203 corresponding to the sieve plates 202 .

As shown in Figure 2, the supporting rods 203 are evenly connected in the screen frame 201, and its two ends are respectively connected on the inner walls of the two opposite sides of the screen frame 201, and a plurality of supporting rods 203 are arranged parallel to each other and are located on the same horizontal plane superior. The sieve plates 202 are respectively fixed above each support bar 203 through the connecting support grooves 204, and the sieve plates 202 are parallel to each other, and the sieve plates 202 intersect with the horizontal plane.

As shown in FIGS. 1 and 2 , the screen 20 is fixed at the feed inlet of the hopper body 10 through a screen frame 201 .

The feeding hopper screening device of the utility model is provided with a bar screen at the feeding port of the feeding hopper, and the material is screened at the same time of feeding, which provides convenience for follow-up work, saves energy, and improves follow-up work. High working efficiency and energy saving. At the same time, the screen adopts bar screen, which is not easy to block holes and improves the screening efficiency.
