Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a screening device for construction waste in cement production. Background Art

[0002] The application of construction waste in cement production is mainly reflected in its reuse as raw material. In the process of cement clinker production, by strengthening the effective control of production links such as raw material homogenization, raw material preparation, and clinker calcination, construction waste such as waste bricks and concrete can be used in the raw material batching plan. Such application not only reduces the stacking cost of construction waste and reduces the raw material cost of clinker production, but also helps to reduce the exploitation of new resources, which is beneficial to the environment and can produce significant economic benefits.

[0003] Because construction waste contains a large amount of steel bars and large blocks of concrete, it cannot be used directly. Usually, when the construction waste enters the factory, it is piled up in the material yard, and the construction waste is spread on the site by a forklift. Employees manually pick and sort stones, steel bars and other debris of different sizes. However, this selection rate is slow and the work intensity is high. In addition, after picking them out, workers need to move them to a fixed location, and the rate of unified collection of the selected debris is slow. Therefore, a construction waste screening device for cement production is proposed to address the above problems. Utility Model Content

[0004] The utility model aims to provide a construction waste screening device for cement production to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Preferably, the bottom end of the shell is fixedly connected to an aggregate shell that passes through the inner side of the shell, the outer side of the aggregate shell is fixedly connected to a vertically arranged leg, a storage box is provided under the aggregate shell, the bottom end of the leg is fixedly connected to a bottom plate, one side of the bottom plate is provided with a conveying device, the conveying device includes a support rod vertically arranged on one side of the leg, the top end of the support rod is fixedly connected to a bearing, the inner side of the bearing is fixedly connected to a horizontally arranged roller, a conveyor belt is provided on the outer side of the roller, and limit plates are symmetrically provided at both ends of the conveyor belt.

[0009] Preferably, the length of the support rod located on the right side of the shell is longer than the length of the support rod located on the left side of the shell, the number of the support rods and bearings is eight, the number of the rollers and limit plates is four, and the outer side of the roller fits tightly with the inner side of the conveyor belt.

[0010] Preferably, the electromagnet is fixedly connected to the inner side of the housing, the number of the screening mechanisms is two, and the aperture of the upper screening plate is larger than that of the lower screening plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, by setting the storage battery, wire, electromagnet, screening mechanism, screen plate, discharge plate and baffle, the classification of construction waste of different sizes is more convenient and the classification speed is faster. When it is necessary to classify the construction waste, the storage battery is started, and the storage battery supplies power to the electromagnet through the wire, and the construction waste is poured into the inner side of the shell. The larger pieces of construction waste are blocked by the screen plate, and thus leave the shell through the discharge plate. The baffle can prevent the waste from leaving the discharge plate from the side. The smaller pieces of construction waste fall onto the lower screen plate through the upper screen plate and are blocked by the lower screen plate, and thus leave the shell through the discharge plate. The baffle can prevent the waste from leaving the discharge plate from the side. The fine powder in the construction waste can pass through the lower screen plate and leave the shell. In this process, the scrap iron in the construction waste can be adsorbed by the electromagnet. When the screening is completed, the container is placed under the electromagnet, and the storage battery is turned off, and the scrap iron can leave the electromagnet and enter the inner side of the container.

[0013] 2. In the utility model, the aggregate shell, legs, storage box, bottom plate, conveying device, support rod, bearing, roller, conveyor belt and limit plate are set, so that the classification and collection rate of sundries is faster. Before use, the roller is connected to a rotating motor and the collection frame is placed under the conveyor belt. When screening construction waste, the rotating motor is started, and the output end of the rotating motor drives the roller to rotate on the inner side of the bearing located at the top of the support rod. The conveyor belt located on the outer side of the roller rotates continuously. The limit plates located on both sides of the conveyor belt can prevent construction waste from escaping from the conveyor belt. The conveyor belt transports the construction waste dropped from the discharge plate to the inner side of the collection frame. After the fine powder in the construction waste passes through the sieve plate, it is concentratedly discharged by the aggregate shell at the top of the legs to the inner side of the storage box located at the top of the bottom plate, thereby completing the classification and collection of construction waste sundries.
