Abstract
Description
Technical Field
[0001] This utility model relates to the field of roller press technology, and in particular to a dust purification device for roller presses. Background Technology
[0002] Roller presses are commonly used in ore processing. They can process ores into smaller particles through extrusion, impact, and grinding to facilitate subsequent mineral refining. Roller presses have the advantage of low energy consumption and have been used more extensively in recent years.
[0003] Because roller presses grind the mined ore, the grinding process generates a lot of dust, smoke, and flying fine stone particles. This dust can have an adverse effect on operators. Currently, many roller press processing sites are not convenient for collecting the dust generated during processing. Spray dust suppression is usually used to reduce some of the dust, but spraying ultimately makes the production site muddy, which has certain limitations. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dust purification device for roller presses.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A dust purification device for a roller press includes a housing and a separation chamber. An annular cover is fixedly installed on the top of the inner wall of the housing via a connecting column. The bottom of the annular cover is inclined. A separation mechanism including an inclined plate and a screen is provided inside the annular cover. A cleaning mechanism including a motor and a wire brush is provided on the top of the annular cover.
[0007] The bottom of the annular cover is fixedly connected to an annular inclined plate, and a hollow separation chamber is fixedly connected to the inner wall of the inclined plate. A screen is installed on the top side wall of the separation chamber, and an air duct is connected to the bottom of the separation chamber. A fan is connected to the end of the air duct.
[0008] The top of the annular cover has a built-in motor, the output shaft of the motor extends out of the top of the annular cover, the end of the output shaft of the motor is fixedly connected to an extension rod, the end of the extension rod is fixedly connected to a vertical connecting rod, and a wire brush is fixedly installed on the side of the connecting rod near the screen.
[0009] Preferably, the bottom of the box is equipped with casters, the top of the box is equipped with a handrail, and one side of the box is equipped with a door.
[0010] Preferably, an adjustable connecting pipe is installed at the center of the top of the box, and a square wide opening is fixedly connected to the end of the connecting pipe. The first end of the connecting pipe is connected to the top of the annular cover.
[0011] Preferably, the bottom of the inclined plate is provided with a discharge port, and a collection box is provided on one side of the bottom of the box body, with the outlet end of the discharge port connected to the side wall of the collection box.
[0012] Preferably, the top side wall of the separation chamber is provided with a track, and a vertical rod is fixedly connected to the extension rod above the track. A roller that abuts against the track is rotatably connected to the bottom of the vertical rod.
[0013] Preferably, a fixing block is fixedly connected to the top of the air duct, the center of the fixing block has a hollow structure, the inner wall of the fixing block has a movable groove, and a vertically set locking rod is slidably connected to one side of the fixing block.
[0014] Preferably, a sliding block is slidably connected inside the movable groove. The center of the sliding block has a hollow structure, and a sponge filter element is installed in the hollow position of the center of the sliding block. A handle is provided on the side wall of the sliding block, and a positioning hole is opened on one side of the sliding block.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention, through the setting of a separation mechanism, allows impurities such as smoke and dust to be absorbed into the annular hood within the housing. The separation mechanism then separates larger objects, such as small stones, from the impurities using a screen. This allows the small stones to be directly isolated outside the separation chamber, while the smoke and dust can pass through the screen into the separation chamber for secondary processing. The isolated small stones can fall into the cavity between the separation chamber and the annular hood and slide down the inclined plate to the discharge port, where they are finally collected by the collection box. This separation mechanism can alleviate the filtration pressure on the sponge filter element, allowing it to work for a longer period and reducing the frequency of replacement. This extends the working time of the smoke and dust purification device, improves work efficiency, and also plays a positive role in protecting equipment and personnel safety at the operating site.
[0017] This invention incorporates a cleaning mechanism that removes small stones that may be stuck on the outer wall of the screen, as well as dust accumulated over time. A motor-driven extension rod rotates, causing a wire brush to continuously clean the screen. This prevents the screen from being obstructed or accumulating dust, thus ensuring the normal operation of the dust removal process. Therefore, the cleaning mechanism, in conjunction with the separation mechanism, can effectively remove and separate small stones and filter dust, extending working time and improving purification efficiency.
[0018] This invention features a sponge filter element. When smoke and dust pass through the sponge filter element, it filters the dust and discharges clean air. Since the sponge filter element is installed in a sliding block, in actual use, the sponge filter element can be removed by manually pulling out the sliding block. After replacing the sponge filter element, the sliding block is pushed back into the movable groove, and the locking rod is inserted into the positioning hole to position and lock the sliding block, preventing accidental movement of the sliding block from affecting the normal operation of the sponge filter element. The replacement operation is convenient. Attached Figure Description

[0028] 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.
[0029] Reference Figure 1-8A dust purification device for a roller press includes a housing 1 and a separation chamber 9. An annular cover 6 is fixedly installed on the top of the inner wall of the housing 1 through a connecting column. The bottom of the annular cover 6 is inclined. A separation mechanism 7 including an inclined plate 8 and a screen 10 is provided inside the annular cover 6. A cleaning mechanism 11 including a motor 12 and a wire brush 17 is provided on the top of the annular cover 6.
[0030] An annular cover 6 is fixedly connected to an annular inclined plate 8 at its bottom end. A hollow separation chamber 9 is fixedly connected to the inner wall of the inclined plate 8. A screen 10 is installed on the top side wall of the separation chamber 9. An air duct 18 is connected to the bottom end of the separation chamber 9. A fan 19 is connected to the end of the air duct 18.
[0031] A motor 12 is built into the top of the annular cover 6. The output shaft of the motor 12 extends out of the top of the annular cover 6. An extension rod 13 is fixedly connected to the end of the output shaft of the motor 12. A vertical connecting rod 16 is fixedly connected to the end of the extension rod 13. A wire brush 17 is fixedly installed on the side of the connecting rod 16 near the screen 10. During ore grinding operations, the roller press generates a lot of smoke and dust, as well as flying small stones, which can pollute the operating area. Therefore, it is necessary to collect these impurities to reduce their adverse effects on the equipment and operators. These impurities are absorbed into the annular hood 6 within the housing 1. The separation mechanism 7 then separates larger objects, such as small stones, from the impurities using a screen 10. Since the separation chamber 9 and the annular hood 6 are connected by an inclined plate 8, and there are cavities between the top and side walls of the separation chamber 9 and the annular hood 6, small stones can be directly isolated outside the separation chamber 9. Smoke and dust can pass through the screen 10 into the separation chamber 9 for secondary processing. The isolated small stones fall into the cavity between the separation chamber 9 and the annular hood 6 and slide down the inclined plate 8 to the discharge port 81, where they are finally collected by the collection box 20. This allows for separation by the separation mechanism 7. The filtration pressure of the sponge filter element 25 allows it to work for a longer period, reducing the frequency of replacement and extending the working time of the dust purification device, thus improving work efficiency and playing a positive role in the safety of equipment and personnel at the operating site. The cleaning mechanism 11 can clean small stones that may be stuck on the outer wall of the screen 10 and the dust accumulated over time. The intersection of the output shaft of the motor 12 and the top of the annular cover 6 is sealed with a sealing ring to prevent dust blockage. The extension rod 13 driven by the motor 12 rotates to drive the wire brush 17 to continuously clean the screen 10, making it less likely for the screen 10 to be affected by jamming and dust accumulation, thus ensuring the normal operation of dust treatment. Therefore, the cleaning mechanism 11, together with the separation mechanism 7, can meet the requirements of small stone screening and separation and subsequent dust filtration, and can extend the working time and improve purification efficiency.
[0032] As a technical optimization of this utility model, a caster wheel 2 is installed at the bottom of the box 1, a handrail is installed at the top of the box 1, and a door 3 is installed on one side of the box 1. The box 1 can be moved by the caster wheel 2, and the position of the box 1 can be easily adjusted according to the site layout when the roller press is used for dust purification.
[0033] As a technical optimization of this utility model, an adjustable connecting pipe 4 is installed at the center of the top of the housing 1. A square wide opening 5 is fixedly connected to the end of the connecting pipe 4, and the head of the connecting pipe 4 is connected to the top of the annular cover 6. The smoke and dust generated on site can be sucked into the connecting pipe 4 through the square wide opening 5 by the suction generated by the fan 19, and then enter the annular cover 6 through the connecting pipe 4 for separation. The separated smoke and dust reach the sponge filter element 25 at the bottom of the separation chamber 9 for filtration, so that impurities such as small stones and smoke are retained in the housing 1, while the air discharged by the fan 19 will not cause pollution to the site.
[0034] As a technical optimization of this utility model, the bottom of the inclined plate 8 is provided with a discharge port 81, and a collection box 20 is provided on one side of the bottom of the box body 1. The outlet end of the discharge port 81 is connected to the side wall of the collection box 20. The side wall of the collection box 20 has a collection opening and the top is sealed, which can conveniently collect small stones and other impurities.
[0035] As a technical optimization of this utility model, a track 14 is provided on the top side wall of the separation chamber 9. A vertical rod is fixedly connected to the extension rod 13 above the track 14, and a roller 15 is rotatably connected to the bottom of the vertical rod, abutting against the track 14. When the motor 12 drives the extension rod 13 to rotate, the roller 15 can roll on the track 14, which can effectively improve the stability of the connecting rod 16 and the wire brush 17, so that the cleaning mechanism 11 can stably and effectively clean the screen 10, ensuring that the screen 10 is not easily blocked.
[0036] As a technical optimization of this utility model, a fixing block 21 is fixedly connected to the top of the air duct 18. The center of the fixing block 21 has a hollow structure, and the inner wall of the fixing block 21 has a movable groove 22. A vertically arranged locking rod 23 is slidably connected to one side of the fixing block 21. The smoke and dust entering the separation chamber 9 eventually flow through the fixing block 21.
[0037] As a technical optimization of this utility model, a sliding block 24 is slidably connected inside the movable groove 22. The center of the sliding block 24 has a hollow structure, and a sponge filter element 25 is installed in the hollow position of the center of the sliding block 24. A handle is provided on the side wall of the sliding block 24, and a positioning hole 26 is opened on one side of the sliding block 24. When smoke and dust pass through the sponge filter element 25, the sponge filter element 25 can filter the dust and discharge clean air. Since the sponge filter element 25 is installed in the sliding block 24, in actual use, the sliding block 24 can be manually pulled out to remove the sponge filter element 25. After replacing the sponge filter element 25, the sliding block 24 is pushed back into the movable groove 22, and the locking rod 23 is inserted into the positioning hole 26 to position and lock the sliding block 24, preventing the sliding block 24 from moving accidentally and affecting the normal operation of the sponge filter element 25.
[0038] In use, the housing 1 is pushed next to the roller press, the angle of the connecting pipe 4 is adjusted so that the square opening 5 is aligned with the top of the roller press, and the fan 19 is started. The suction force generated by the fan 19 draws the dust generated on site into the connecting pipe 4 through the square opening 5, and then into the cavity between the separation chamber 9 and the annular cover 6. At this time, larger objects such as small stones are separated by the screen 10, while the dust can pass through the screen 10 into the separation chamber 9 for secondary processing. The isolated small stones can fall into the cavity between the separation chamber 9 and the annular cover 6 and slide down the inclined plate 8 to the discharge port 81, and finally be discharged. The collection box 20 collects dust, in which the motor 12 drives the extension rod 13 to rotate and the roller 15 can roll on the track 14, driving the wire brush 17 to continuously clean the screen 10. When the dust flowing into the separation chamber 9 passes through the sponge filter element 25, the sponge filter element 25 can filter the dust and expel clean air. When the sponge filter element 25 needs to be replaced, the locking rod 23 is pulled out of the positioning hole 26, and the sliding block 24 can be manually pulled out to remove the sponge filter element 25. After replacing the new sponge filter element 25, the sliding block 24 is pushed into the movable groove 22, and the locking rod 23 is inserted into the positioning hole 26 to position and lock the sliding block 24.
[0039] 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.
