Description

Technical Field

[0001] This utility model belongs to the field of stone chip separation and collection technology, and in particular relates to a stone chip separation and collection device for limestone powder production. Background Technology

[0002] Limestone powder production refers to the process of crushing and grinding natural limestone to produce powder products of a specific fineness. Limestone chips are naturally formed products during the limestone crushing process. Collecting them has multiple values, including environmental protection, resource utilization, and optimized economic benefits.

[0003] Currently, after limestone is crushed, the stone chips follow the fragments directly into the area where the screen is located for separation. However, the impact force generated when the fragments fall constantly impacts the screen, causing the screen to be easily damaged, which increases maintenance costs and hinders subsequent separation operations.

[0004] To address the aforementioned problems, this application proposes a limestone powder production stone chip separation and collection device. Utility Model Content

[0005] The purpose of this invention is to provide a limestone powder production stone chip separation and collection device, 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 is a limestone powder production stone chip separation and collection device, including a crusher and its internal crushing roller. The rear end of the crusher is detachably equipped with a sealing plate, and the right side of the crusher has a discharge port at both the front and rear.

[0008] The crusher has a partition hinged inside, located above the storage chamber at the bottom. A screening mechanism is slidably installed above the storage chamber, located below the partition to close the storage chamber.

[0009] The screening mechanism includes screen one, screen two, and screen three, distributed from left to right. Screen two has a concave semi-circular structure. A material-pulling rod is rotatably installed inside the crusher and located inside screen two. A protrusion is fixed on the upper surface of screen three.

[0010] Preferably, an opening is formed between the partition and the left inner wall of the crusher, and a paddle is rotatably installed inside the crusher.

[0011] Preferably, the lever is located directly above the axis of the feeding rod and between the partition plate, with the lower end of the lever intersecting the feeding rod and the upper end of the lever abutting against the partition plate.

[0012] Preferably, the front and rear inner walls of the crusher have protruding support plates distributed on the left and right sides of the deflector plate, and a strong spring rod is fixedly installed on the support plate near the deflector plate.

[0013] Preferably, the left end of the screen is fixed downwards with a side plate, and a bottom plate is provided below it to engage with the plate protruding from the bottom of the left inner wall of the crusher.

[0014] Preferably, the right end of the screen three is fixed downward with a side plate two, and a seat plate is provided below the guide slope extending from its right side, which is slidably installed below the plate protruding from the bottom of the right inner wall of the crusher.

[0015] Preferably, the upper ends of the base plate and the seat plate are each fixed with a telescopic spring rod that is respectively fixedly connected to the side plate and the bottom surface of the guide slope.

[0016] Preferably, the guide slope has discharge ports fixed at both ends, which are inserted inside the discharge port.

[0017] This utility model has the following beneficial effects:

[0018] This invention uses a partition and a screening mechanism arranged in upper and lower sections to buffer falling stones before they enter the screening area. This not only avoids damage to the screening mechanism caused by long-term impact, but also ensures effective separation of stones and stone chips during long-term operation.

[0019] This invention utilizes the rotating feeding of the second screen and the blocking of the protrusions to promote the passage of stone chips through the mesh into the storage cavity in separate sections. At the same time, the raised structure of the protrusions allows the stones to enter individually for feeding, thereby achieving a sufficient separation effect and facilitating subsequent processing.

[0035] 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.

[0036] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship 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.

[0037] Please see Figure 1-5 As shown, this utility model is a limestone powder production stone chip separation and collection device, including a crusher 11 and a crushing roller 12 inside it. A sealing plate 13 is detachably installed at the rear end of the crusher 11, and a discharge port 14 is opened at both the front and rear of the right side of the crusher 11.

[0038] The crusher 11 has a partition 21 hinged inside, located above the storage chamber 23 at the bottom, which is used to buffer the crushed stones and stone chips falling down and prevent them from directly impacting the screening mechanism. The screening mechanism is slidably installed above the storage chamber 23 and below the partition 21 to close the upper opening of the storage chamber 23.

[0039] The screening mechanism includes screen 1 221, screen 222, and screen 3 223, distributed from left to right. Screen 222 is a concave semi-circular structure. Screen 1 221 is inclined downward at about 15° from the left end to the right end to guide the sliding of stones and stone chips. Screen 3 223 has an increased slope of about 15° compared to screen 1 221 to increase the gravitational potential energy of the stones sliding down. Inside the crusher 11, there is a rotating material-pushing rod 25 located inside screen 222. The material-pushing rod 25 is arranged at equal intervals front and back and rotates from left to top to right to lift the stones and promote the downward separation of stone chips. The upper surface of screen 3 223 is fixed with protrusions 2231. Under the action of gravitational potential energy, the stones are pushed upward and enter the feeding area alone to increase the degree of stone chip separation. The adjacent protrusions 2231 form a blocking isolation area for the stone chips, so that they can be finally separated in this area.

[0040] Furthermore, an opening is formed between the partition plate 21 and the left inner wall of the crusher 11 to allow the buffered stones and stone chips to enter the screening area. Inside the crusher 11, a rotatable baffle plate 24 is installed, located directly above the axis of the material feeding rod 25. By rotating, it drives the partition plate 21 to swing up and down, thereby preventing blockage at the opening from affecting the material feeding. The lower end of the baffle plate 24 is intersected with the material feeding rod 25. When the material feeding rod 25 rotates past, it drives the baffle plate to rotate. The upper end of the baffle plate 24 abuts against the partition plate 21. When rotating, the support height of the partition plate 21 changes, causing it to swing up and down.

[0041] Furthermore, the front and rear inner walls of the crusher 11 have protruding support plates 241 located on the left and right sides of the push plate 24. A strong spring rod 2411 is fixedly installed on the side of the support plate 241 near the push plate 24. It is used to absorb the extrusion force when the push plate 24 rotates, and then form a reverse force on the push plate 241 after the push rod 25 passes, thereby driving it to reset.

[0042] Furthermore, a side plate 224 is fixed downwards at the left end of screen 1 221, and a bottom plate 2241 is provided below it. The left opening of the bottom plate 2241 is slidably connected to the plate protruding from the bottom of the left inner wall of the crusher 11. After the sealing plate 13 is fixed, it becomes a snap-fit ​​connection. The side plate 224 is located between the left vertical plate of the storage chamber 23 and the left inner wall of the crusher 11. A side plate 225 is fixed downwards at the right end of screen 3 223, and a seat plate 2252 is provided below the guide slope 2251 extending from its right side. It is slidably installed below the plate protruding from the bottom of the right inner wall of the crusher 11. The side plate 225 is located between the right vertical plate of the storage chamber 23 and the right inner wall of the crusher 11.

[0043] The upper ends of the base plate 2241 and the seat plate 2252 are both fixed with telescopic spring rods 2201, which are fixedly connected to the bottom surfaces of the side plate 224 and the guide slope 2251, respectively. These rods are used to drive the stones to vibrate slightly up and down when they fall above the screening mechanism, thereby promoting the separation of stone chips and the downward movement of the stones.

[0044] Furthermore, the two ends of the guide slope 2251 are fixed with discharge ports 2253 that pass through the inside of the discharge port 14, and the top of the discharge port 14 is reserved with space required for the discharge ports 2253 to move up and down due to the vibration of the screening mechanism.

[0045] It is understandable that this utility model can buffer the limestone after it is crushed, preventing damage caused by direct impact on the screening mechanism. At the same time, it can also form a multi-stage screening effect, thereby discharging the stones separately, which is convenient for subsequent transportation and processing.

[0046] A specific application of the operation process of this embodiment is as follows: During use, the crushed stones are first blocked by the partition 21 and guided to the opening at the left end, and then fall above the screening mechanism for separation. During the separation, the stones and stone chips first slide to the lower right on the surface of screen 1 221 to form primary separation. Then the stones and the remaining stone chips enter screen 222. At this time, the stones are lifted by the push rod 25, while the stone chips pass through 22 and enter the storage cavity 23 to form secondary separation. The lifted stones rotate from left to right and enter screen 3 223. The increased slope of screen 3 223 increases the gravitational potential energy of the stones, so that they are pushed upward when they hit the protrusion 2231. The stone chips are blocked due to their lower gravitational potential energy and are then separated into the interior of the storage cavity 23. The lifted stones pass over the protrusion 2231 and enter the guide slope 2251 alone, and finally pass through 2553 and are discharged outward.
