Description

Technical Field

[0001] The utility model relates to the technical field of cement processing and screening, in particular to a screening device for cement processing. Background Art

[0002] Cement is a powdery hydraulic inorganic gelling material, which becomes a slurry after adding water and stirring. It can harden in the air or in water, and can firmly bond materials such as sand and stone together. Cement is one of the important building materials and is widely used in civil construction, water conservancy, national defense and other projects. When in use, cement is usually mixed with aggregates such as sand and stone, and stirred with water to form concrete for the construction of building structures. In addition, cement can also be used alone, such as for plastering and repairing. Cement is an indispensable material in construction projects. In cement production and cement processing, the particle size of cement raw materials has a decisive influence on the quality of cement. Therefore, in the cement processing process, in order to remove fine particles in the raw materials, a screening device is required.

[0003] The existing Chinese authorized utility model patent (publication number: CN216261889U) discloses a multi-stage screening device for raw materials for cement mortar production. The first sprocket is driven to rotate by a reduction motor, so that the second sprocket can be driven to rotate through the chain, and the second sprocket drives the driving gear to drive the driven gear to rotate, and then the first sprocket drives the first rotating rod to rotate, and the driven gear drives the second rotating rod to rotate, and then the first rotating rod and the second rotating rod drive the first driving plate and the second driving plate to rotate, so that the rack plate matched with the first driving plate and the second driving plate can drive the corresponding screen plate to move, and the screen plate can be made to reciprocate through the cooperation of the spring column, thereby realizing multi-stage screening processing of building raw materials, obtaining building raw materials with uniform particle size, and effectively improving the screening efficiency of building raw materials. In the process of implementing the scheme, the inventor discovered that the scheme had the following problems during implementation: when the device is in use, the components for realizing multi-stage screening are all installed on the side walls inside the screening box. Therefore, when the multi-stage screening device for raw materials for cement mortar production is used multiple times, according to the properties of cement, it is easy for accumulation to appear on the screen plate, causing the screen plate to become blocked, affecting the secondary use of the multi-stage screening device for raw materials for cement mortar production. The screening box is fixed as a whole, and when the screen plate needs to be cleaned, the operation is relatively inconvenient and not convenient to use, which affects the screening operation of cement processing. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the components for realizing multi-stage screening are all installed on the side wall inside the screening box. Therefore, when the multi-stage screening device for raw materials for cement mortar production is used multiple times, according to the properties of cement, it is easy to accumulate on the screen plate, thereby causing the screen plate to be blocked, affecting the secondary use of the multi-stage screening device for raw materials for cement mortar production. The screening box is fixed as a whole, and when it is necessary to clean the screen plate, the operation is inconvenient and the use is not convenient enough, which affects the screening operation of cement processing. A screening device for cement processing is proposed.

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

[0006] A screening device for cement processing comprises a first box body, one side of which is provided with an opening, and a screening mechanism is slidably installed inside the first box body;

[0011] Preferably, a slide groove is provided on the first plate body, and two racks and a gear are arranged on the slide groove.

[0012] The utility model has the following beneficial effects:

[0013] 1. When the screens of the two frames need to be cleaned, the screening mechanism can be pulled as a whole to separate the first box body from the screening mechanism, thereby facilitating the cleaning of the first box body and the screening mechanism. The operation is more convenient and is helpful for the screening operation of cement processing.
