Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ore dressing equipment, and particularly relates to a mud-stone separator. BACKGROUND

[0002] The mud-stone separator is a material screening device commonly used in the mining, construction, metallurgy and other industries, and is mainly used for classifying, grading and separating ore, coal, sandstone and other materials, and has a significant advantage especially in the processing of mineral substances accompanied by a large amount of soil in the mining process. The device usually works through a vibrating screen, a roller screen or a chain separation, and the soil is separated from the stones through the impact, vibration or rolling of the material. The mud-stone separator can effectively reduce the soil content in the subsequent processing link, reduce the wear and blockage of the equipment, and improve the working efficiency of the entire production line.

[0003] The roller screen is a screening device that realizes the screening of materials through a plurality of parallel arranged screen plates or screen teeth on rotating shafts. The roller screen utilizes the rolling of the material on the screen surface and the size of the screen hole to screen out the material meeting the particle size requirement, and the remaining material is transported to the next process. This screening method is particularly suitable for screening wet and sticky materials, and can effectively avoid screen hole blockage. At the same time, due to the self-cleaning function of the roller, the screening efficiency is high. The roller screen has the characteristics of simple structure, convenient operation and easy maintenance, and is widely used in the coal, sandstone, ore and other industries.

[0004] The transmission mechanism, as the core component of the roller screen, plays a crucial role in the smooth and efficient operation of the screen surface. In the past, the driving mode of the mine multi-screen shaft device was mainly chain wheel driving. Compared with chain wheel transmission, gear transmission has high transmission precision, strong carrying capacity, compact structure, long service life and stable transmission. The Chinese utility model patent CN201621423701.7 records that the same direction rotation of all screen shafts is realized by adding an idler wheel. However, the size of the idler wheel increases the distance between the transmission shafts, which is not conducive to the compactness and precision manufacturing of the equipment structure. At present, there is no efficient, compact and high-precision solution based on gear transmission. Based on this, the present application is proposed. SUMMARY

[0005] To effectively solve or at least alleviate one or more of the problems in the prior art and other aspects, the present application provides the following technical solutions.

In other embodiments, the above-mentioned double-row gear transmission structure can be distributed at one end or both ends of the transmission shaft according to the specific installation space of the equipment, and a multi-row gear transmission structure can also be designed according to the load bearing capacity of the equipment.

[0028] In the present embodiment, a sprocket is arranged on the transmission shaft, specifically, a first sprocket 9 is arranged on one of the first transmission shafts 2, and a second sprocket 10 is arranged on one of the second transmission shafts 3, the first sprocket 9 and the second sprocket 10 are in position correspondence, a chain is arranged on the sprocket to form a sprocket transmission system, and the first transmission shaft 2 and the second transmission shaft 3 move synchronously under the action of the sprocket transmission system. In other specific embodiments, a plurality of sprockets can be designed according to the actual situation of the equipment.

[0029] In the present embodiment, a motor arranged on the transmission shaft is designed for the mud-stone separator, specifically, a first permanent magnet motor 11 is arranged at the first end of one of the first transmission shafts 2, and a second permanent magnet motor 12 is arranged at the first end of one of the second transmission shafts 3, and the first permanent magnet motor 11 and the second permanent magnet motor 12 respectively drive the transmission shafts connected thereto to move in the same direction. In other embodiments, a plurality of motors can be designed according to the actual situation of the equipment.

[0030] In the embodiment, the debris separator is designed with a processing jamming device 13 arranged at one end of a transmission shaft to prevent reverse rotation of the transmission shaft. The processing jamming device 13 comprises a star wheel 131 fixed on the transmission shaft, a sleeve 132 fixed on the machine base, and a roller 133 arranged in a wedge-shaped space formed by the star wheel and the sleeve. The sleeve is provided with an elastic pushing mechanism 134 for applying a pre-tightening force to the roller. When the transmission shaft rotates in the forward direction, the roller 133 is located at the wide end of the wedge-shaped space, and the processing jamming device is separated. When the transmission shaft on which the processing jamming device is arranged rotates in the reverse direction, the roller 133 is wedged into the narrow end of the wedge-shaped space under the action of the pre-tightening force, thereby achieving backstop. The bottom of the processing jamming device is provided with a connecting rod 14 and / or a push rod 15 for controlling the processing jamming device and preventing large block materials from being jammed.

[0031] In the embodiment, as shown in Figure 4 and Figure 5 , the working steps of the processing jamming system are as follows: S1: when the debris separator is normally operated, the star wheel of the anti-jamming device is rotated by the transmission shaft, and the sleeve does not rotate with the star wheel; S2: when the debris separator is jammed, the driving device alarms and stops, the star wheel on the transmission shaft stops rotating, and the sleeve fixed on the machine base and the star wheel are connected into a whole through the roller; S3: under the premise that the motor does not rotate, the push rod at the bottom of the anti-jamming device is started to drive the connecting rod and push the sleeve and the star wheel, the transmission shaft as a whole to form a squeezing effect between the adjacent shafts without backstop, thereby providing a crushing force to the jammed material. S4: after crushing the jammed material, the motor can be started again.

[0032] In other embodiments, the processing jamming device can be arranged as one or more according to process requirements.

[0033] In the embodiment, as shown in Figure 4 and Figure 5 , the working principle of the processing jamming device is as follows: during operation, the debris separator may face the problem of jamming, which will seriously affect the work efficiency if not properly and quickly solved. Figure 5The working principle of the processing card device based on the processing card device is shown, and when working normally, the star wheel 131 of the processing card device 13 connected with the first transmission shaft 2 or the second transmission shaft 3 rotates clockwise, that is, the outer sleeve 132 rotates counterclockwise relative to the star wheel 131. However, when a large block of material is blocked, the machine is manually controlled to stop, all the first transmission shaft 2 or the second transmission shaft 3 stops rotating and remains fixed, the processing card device 13 is pushed by the push rod 15, the outer sleeve 132 rotates towards the original rotating direction of the first transmission shaft 2 or the second transmission shaft 3, at this time, the processing card device outer sleeve 132 rotates clockwise relative to the star wheel 131, so that the processing card device presents a "check" state, by holding the first transmission 2 shaft or the second transmission shaft 3 connected thereto and driving it to rotate clockwise, finally the rigid extrusion of the outer sleeve 132 is used to extrude and clean the blocked material. The extrusion force depends on the pushing force of the electro-hydraulic push rod 15 and the length of the outer sleeve 132 (i.e. force and force arm), and repeated extrusion can be realized by repeated extension and contraction of the push rod 15. The processing card device of the present application ensures that the equipment always maintains a stable rotating direction during operation, avoids the possible reverse problem, and improves the reliability of the system. In addition, when the material is blocked, the processing card device can extrude and clean the blocked material under the action of the push rod, reducing the need for manual cleaning and improving the working efficiency of the equipment.

[0034] Compared with the prior art, the present application has the following beneficial effects: 1) A double-row gear transmission system is adopted, and the driving wheel and the idler wheel are coaxial and cross-distributed, so that all the transmission shafts can rotate in the same direction. Compared with the transmission mode in the prior art, more transmission shafts can be arranged in a limited space, the arrangement is more compact, the carrying capacity of the equipment is improved, and the service life of the equipment is improved.

[0035] 2) The double-row gear transmission system is combined with the chain wheel transmission to "bind" the power of the first transmission shaft and the second transmission shaft, which can reduce the number of permanent magnet motors or processing card devices, improve the flexibility and overall performance of the system.

[0036] 3) Since the processing card device and the processing card function are designed, the problems of lack of effective prevention of reverse rotation of the transmission shaft and material blocking in the existing gear transmission system are overcome, and the reliability of the system is improved.

[0037] The embodiments in the above examples can be further combined or replaced, and the examples only describe the preferred embodiments of the present application, but do not limit the concept and scope of the present application. Without departing from the design idea of the present application, various changes and improvements to the technical solutions of the present application made by those skilled in the art all belong to the protection scope of the present application.
