Description

Technical Field

[0001] This utility model relates to the technical field of ore processing equipment, and in particular to a crushing and dust removal device for magnesite ore. Background Technology

[0002] Magnesite needs to be crushed during mining to facilitate subsequent transportation and processing. A Chinese patent application (application number 202321126140.4) discloses an ore crusher, including a casing, a feed hopper, a first crushing chamber, and a second crushing chamber. A screen cylinder is rotatably connected to the top of the casing. The left end of the screen cylinder has an inlet connected to the feed hopper, and the right end has an outlet connected to the first crushing chamber. An inclined plate is installed at an angle inside the casing below the screen cylinder. The left end of the inclined plate forms an opening with the casing, connecting to the second crushing chamber. The screen cylinder has multiple screen holes. The right end of the screen cylinder is lower than the left end, and the right end of the inclined plate is higher than the left end. The device also includes a power unit to drive the screen cylinder to rotate.

[0003] The above-mentioned technology has an anti-clogging effect by setting a rotatable screen cylinder. However, since no dust removal device is set, dust will be generated when the ore rotates in the screen cylinder and during subsequent crushing, which will have an adverse effect on the external environment and personnel. Therefore, in order to solve the above-mentioned technical defects, we propose a crushing and dust removal device for magnesite. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a crushing and dust removal device for magnesite ore.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A crushing and dust removal device for magnesite ore includes a main body of crushing equipment for ore crushing. The feed inlet of the main body of the crushing equipment is connected to an installation box via an upwardly inclined connecting pipe. The installation box has spaced-apart isolation plates and sealing plates inside. The side of the isolation plates and sealing plates away from the main body of the crushing equipment and the inner wall of the installation box are provided with a matching tension spring. The bottom of the installation box is provided with filter holes corresponding to the isolation plates and sealing plates. The bottom of the outer surface of the installation box is provided with a matching connecting pipe corresponding to the filter holes. The lower end of the connecting pipe is connected to a settling box, and the upper end of the settling box is connected to an exhaust fan.

[0007] Preferably, a connecting cylinder is installed at one end of the upper side of the settling box, and a baffle net is provided inside the connecting cylinder. The air inlet of the exhaust fan is connected to the connecting cylinder through an air guide pipe.

[0008] Preferably, the front side of the settling tank is open and equipped with a sealing door, which is a transparent plate.

[0009] Preferably, the settling tank is equipped with a collection box inside, and the collection box is a transparent box.

[0010] Preferably, the upper end of the settling tank is provided with a flexible tube, the lower end of the flexible tube is located inside the collection box, and the upper end of the flexible tube is connected to the lower end of the connecting tube.

[0011] Preferably, the upper end of the mounting box is provided with a mounting plate, and the mounting plate has a plurality of observation windows.

[0012] Preferably, the mounting plate has a limiting cover on its lower side, and the end of the tension spring away from the isolation plate and the sealing plate is installed inside the limiting cover.

[0013] The present invention provides a crushing and dust removal device for magnesite ore, which has the following advantages:

[0014] 1. In this utility model, the exhaust fan generates suction inside the settling box, and this suction is transmitted to the installation box through the connecting pipe. This allows the dust-laden, turbid air inside the installation box to enter the connecting pipe through the filter holes. The diameter of the filter holes is set according to specific usage requirements, ensuring that the ore to be crushed cannot pass through the filter holes into the connecting pipe. In summary, the installation box, isolation plate, and sealing plate prevent dust generated during magnesite ore screening and crushing from leaking directly to the outside, thus ensuring a clean external environment and protecting personnel health. Furthermore, the settling box and exhaust fan continuously collect dust from the installation box, preventing dust leakage during material feeding. Through the coordinated operation of these components, the defect of dust leakage during magnesite ore screening and crushing, which could adversely affect the external environment and personnel, can be effectively avoided.

[0015] 2. The barrier net in this utility model facilitates secondary filtration of turbid gas entering the chamber when the exhaust fan is running, thereby improving dust collection efficiency and reducing the maintenance frequency of the exhaust fan. The connecting tube facilitates connection between the exhaust fan and the settling box, and also allows for easy replacement of the barrier net, enhancing the convenience of use. The sealed door facilitates cleaning of the dust collected inside the settling box and allows for observation of the dust collection volume. The collection box further enhances the convenience of dust collection and observation. The flexible tube, without excessively affecting the placement and retrieval of the collection box, allows the collected dust to settle within it, facilitating quick and easy removal.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Reference Figure 1-6 A crushing and dust removal device for magnesite ore includes a crushing equipment body 1 for crushing ore. The feed inlet of the crushing equipment body 1 is connected to an installation box 3 via an upwardly inclined connecting pipe 2. The installation box 3 is rotatably equipped with spaced-apart isolation plates 4 and sealing plates 5. The side of the isolation plates 4 and sealing plates 5 away from the crushing equipment body 1 is provided with a matching tension spring 6 between them and the inner wall of the installation box 3. The bottom of the installation box 3 is provided with filter holes corresponding to the isolation plates 4 and sealing plates 5. The bottom of the outer surface of the installation box 3 is provided with a matching connecting pipe 7 corresponding to the filter holes. The lower end of the connecting pipe 7 is connected to a settling box 8, and the upper end of the settling box 8 is connected to an exhaust fan 9.

[0026] Example 2

[0027] Reference Figure 1-6 While all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0028] A connecting cylinder 10 is installed at one end of the upper side of the settling box 8. The interior of the connecting cylinder 10 is equipped with a baffle net 11. The air inlet of the exhaust fan 9 is connected to the connecting cylinder 10 via a duct. The front of the settling box 8 is open and equipped with a sealing door 12, which is a transparent plate. Inside the settling box 8 is a collection box 13, which is also transparent. A flexible tube 14 is located at the upper end of the settling box 8, with its lower end inside the collection box 13. The upper end of the flexible tube 14 is connected to the lower end of the connecting pipe 7. The baffle net 11 facilitates secondary filtration of the turbid gas entering the settling box 8 during operation of the exhaust fan 9, thereby improving dust collection efficiency and reducing the maintenance frequency of the exhaust fan 9. The connection tube 10 facilitates the connection between the exhaust fan 9 and the settling box 8, and also allows for easy replacement of the barrier net 11, thus improving the convenience of using this solution. The sealing door 12 facilitates the cleaning of the dust collected inside the settling box 8 and allows for observation of the amount of dust collected inside the settling box 8. The collection box 13 further enhances the convenience of collecting dust inside the settling box 8 and observing the amount of dust inside the settling box 8. The flexible tube 14 allows the collected dust to settle inside the collection box 13 without excessively affecting the placement and retrieval of the collection box 13, thus facilitating the centralized and rapid removal of the collected dust.

[0029] The upper end of the mounting box 3 is provided with a mounting plate 15, and the mounting plate 15 is provided with several observation windows 16. The lower side of the mounting plate 15 is provided with a limiting cover 17. The end of the tension spring 6 away from the isolation plate 4 and the sealing plate 5 is installed inside the limiting cover 17. The mounting plate 15 is designed to facilitate personnel to observe the operating status inside the mounting box 3, so as to clean the filter holes in time when they are clogged, and also to facilitate personnel to replace the tension spring 6. The limiting cover 17 is designed to limit the isolation plate 4 and the sealing plate 5, so as to ensure that dust cannot leak from the inside of the mounting box 3 to the outside.

[0030] Operating principle and advantages: In operation, magnesite ore enters the installation box 3 from the end furthest from the connecting pipe 2, i.e., from the higher end of the installation box 3. It then slides down the installation box 3 until it passes through the connecting pipe 2 and falls into the main body of the crushing equipment 1. There, it is screened and crushed, thus completing the crushing process of the magnesite ore. During this process, the exhaust fan 9 generates suction inside the settling tank 8, and this suction is transmitted to the installation box 3 through the connecting pipe 7. The dust-laden, turbid air inside the installation box 3 enters the connecting pipe 7 through the filter holes, and finally enters the settling box 8. At this time, the heavier, larger dust particles settle inside the settling box 8 for subsequent centralized treatment, such as being used as filler or for secondary processing, while the lighter, smaller dust particles enter the exhaust fan 9 with the flowing air and are intercepted and filtered. Then, the fine dust that meets the emission standards is discharged to the outside with the air. The exhaust end of the exhaust fan 9 can also be connected to other external gas treatment facilities for ultimate dust removal.

[0031] Furthermore, in the above process, the isolation plate 4 and the sealing plate 5 divide the interior of the installation box 3 into two independent spaces. The dust generated during screening and crushing of magnesite in the main body of the crushing equipment 1 is isolated by the isolation plate 4. Therefore, only intermittent feeding is required into the installation box 3. When the ore pushes open the sealing plate 5 and enters the installation box 3 but has not yet reached the isolation plate 4, the dust cannot break through the obstruction of the isolation plate 4 and leaks out to the outside in large quantities. After all the ore has passed through the sealing plate 5, the sealing plate 5 resets under the action of the tension spring 6, and re-seals one end of the installation box 3 at the top. At this time, the ore inside the installation box 3 reaches the isolation plate 4 and pushes the isolation plate 4 to flip, so that the ore enters the main body of the crushing equipment 1. After the ore enters the main body of the crushing equipment 1, the isolation plate 4 resets. During the flipping process of the isolation plate 4, the dust that breaks through the blockage of the isolation plate 4 and enters the middle of the installation box 3 is blocked by the sealing plate 5, so that it still cannot directly leak to the outside.

[0032] It should be further explained that the barrier net 11 facilitates secondary filtration of the turbid gas entering the exhaust fan 9 during operation, thereby improving dust collection efficiency and reducing the maintenance frequency of the exhaust fan 9. The connecting tube 10 facilitates connection between the exhaust fan 9 and the settling box 8, and also allows for easy replacement of the barrier net 11, thus improving the convenience of use. The sealing door 12 facilitates cleaning of the dust collected inside the settling box 8 and allows for observation of the dust collection volume. Furthermore, the collection box 13 further... The improved design enhances the convenience for personnel to collect dust inside the settling box 8 and observe the amount of dust inside the settling box 8. The flexible tube 14 facilitates the settling of collected dust inside the settling box 13 without excessively affecting the placement and retrieval of the settling box 13, thus making it easy for personnel to quickly and centrally remove the collected dust. The mounting plate 15 facilitates the observation of the operating status inside the mounting box 3, enabling timely cleaning when the filter holes are clogged, and also facilitates the replacement of the tension spring 6. The limiting cover 17 facilitates the limiting of the isolation plate 4 and the sealing plate 5, so as to ensure that dust cannot leak from the inside of the mounting box 3 to the outside.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
