Abstract
Description
Technical Field
[0001] This utility model belongs to the field of screening technology, and in particular relates to a screening device for processing cement gangue raw materials. Background Technology
[0002] Coal gangue is an important raw material for clinker in cement production. It can form important components such as iron oxide, aluminum and silicates in clinker. The collected coal gangue needs to be crushed and screened and then undergo a series of preparation processes to obtain the required cement. It not only serves as an important raw material, but also improves cement performance and reduces costs, while meeting environmental protection requirements.
[0003] Currently, in the crushing of coal gangue, the stone is often discharged directly and needs to be manually screened before it can enter the next process. This undoubtedly takes up a lot of time and affects the production efficiency. In addition, the uneven size of the crushed stone will also affect the production quality.
[0004] To address the aforementioned issues, this application proposes a screening device for processing cement gangue raw materials. Utility Model Content
[0005] The purpose of this invention is to provide a screening device for processing cement gangue raw materials, which solves the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a screening device for processing cement gangue raw materials, comprising: a main body of the equipment and a pre-crushing roller inside it; a slide bar, which is installed obliquely inside the main body of the equipment and divides the internal space of the main body of the equipment into an upper pre-crushing zone and a lower fine crushing zone, for intercepting stone materials to form a screening zone; a deflector plate, which is evenly distributed on the outside of the transmission belt, for sending the intercepted stone materials back to the upper area for secondary crushing; and a transmission box, which is located at the front of the main body of the equipment and has an adapter seat on the outside that connects to the shaft seat in front of the side box, for providing rotational power to the transmission belt.
[0008] Furthermore, the transmission belt has transmission rods evenly distributed inside, with the transmission rods in the upper region connected to the shaft seat.
[0009] Furthermore, a return port is provided on the upper inner side of the side box to send the intercepted stone back to the crushing area of the pre-crushing roller.
[0010] Furthermore, a feed inlet is provided on the inner side of the lower end of the side box, and the stone material automatically passes through the feed inlet and enters the side box under the guidance of the slide rod.
[0011] Furthermore, a guide plate is provided below the return port to guide the stone to a predetermined area.
[0012] Furthermore, an inclined plate is provided below the feed inlet to fix the slide bar in a predetermined inclined state.
[0013] Furthermore, the slide bar intercepts the stone and also prevents the stone from directly contacting the crushing equipment, thus preventing increased wear.
[0014] This utility model has the following beneficial effects:
[0015] This invention uses parallel sliding rods to intercept larger stones, which are then fed back to the upper area for secondary crushing via a deflector plate. The screening process can be completed automatically inside the equipment, eliminating the need for subsequent screening and allowing the stones to be directly used in the next process. This improves work efficiency and the quality of stone crushing, effectively ensuring the quality of cement production.
[0016] This invention intercepts and re-feeds larger stones, and can also install different crushing devices inside the main body of the equipment to prevent large stones from directly entering the crushing area and causing high-speed wear and damage to the devices. This ensures the crushing quality while extending the service life of the equipment and facilitates continuous operation during large-scale crushing operations.
[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] 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.
[0026] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0027] Please see Figure 1-4 As shown, this utility model is a screening device for processing cement gangue raw materials, including: the main body of the equipment 1 and the pre-crushing roller 3 inside it;
[0028] The slide bar 14, located inside the main body 1 of the equipment, is an inclined installation structure that divides the internal space of the main body 1 of the equipment into an upper pre-crushing zone 10 and a lower fine crushing zone 11. It is used to intercept stone materials to form a sieve. The slide bar 14 intercepts the stone materials and also prevents the stone materials from directly contacting the crushing equipment, which would lead to increased wear.
[0029] The paddle plate 8 is evenly distributed on the outside of the transmission belt 7 and is used to send the intercepted stone back to the upper area for secondary crushing.
[0030] The transmission box 4 is located in front of the main body 1 of the equipment. The outer side is provided with an adapter 6 connected to the bearing 5 in front of the side box 2, which is used to provide rotational power for the transmission belt 7.
[0031] This embodiment provides an automatic screening structure for the crushing equipment. By using the equally spaced slide bars 14, stones of a predetermined size can be automatically intercepted and then crushed a second time under the drive of the deflector plate 8. This not only prevents large stones from directly contacting the crushing equipment and protects it from increased wear, but also ensures that the resulting fine crushed stones are of uniform size and can be directly used in the next process.
[0032] The transmission belt 7 has transmission rods 9 evenly distributed inside, and the transmission rods 9 in the upper area are connected to the bearing 5 to make full use of the equipment's drive equipment and reduce the equipment's operating energy consumption.
[0033] The upper inner side of the side box 2 is provided with a return port 12, and a guide plate 15 is provided below the return port 12 to guide the intercepted stone to a predetermined area for secondary crushing.
[0034] The side box 2 has a feed inlet 13 on the lower inner side, and a sloping plate 16 is provided below the feed inlet 13 to fix the slide rod 14 in a predetermined inclined state. Under the guidance of the slide rod 14, the stone automatically passes through the feed inlet 13 and enters the side box 2.
[0035] It is understood that this utility model can directly screen stone materials inside the crushing equipment, so that they can be fully crushed, improve production quality, and at the same time protect the crushing tools to prevent excessive wear caused by excessively large stones, thereby increasing the service life of the equipment. It can also improve the processing accuracy of the crushing area, which is convenient for cement production.
[0036] A specific application of the operation process in this embodiment is as follows: In use, the stone is first pre-crushed by the pre-crushing roller 3, breaking it into small stones. The slide bar 14 intercepts larger stones and guides them. After entering the feed inlet 13, the slide plate 8 sends them to the upper area for secondary crushing. This not only automatically forms a sieve to ensure the quality of stone crushing, but also prevents large stones from directly abrading the crushing equipment, thus protecting it and improving the service life of the equipment. It is suitable for large-scale crushing operations. The material formed in this way can be directly used in the next process without manual screening.
