Description

Technical Field

[0001] The utility model relates to gravity ore dressing equipment, in particular to a high separation ratio steel frame shaking table. Background Art

[0002] The shaking table is a traditional gravity separation equipment. The principle is to use the density difference between minerals to separate light and heavy minerals, so as to obtain the concentrate product of the target mineral. In many heavy metal mines such as tungsten-tin mines and gold mines, the shaking table is the main separation equipment, and this dominant position will continue. Therefore, it is still of great significance to strengthen the research and development of traditional shaking tables and improve and innovate them.

[0003] As we all know, the main structure of a traditional rocking bed is a wooden frame. First of all, the wood needs to be prepared. First, logs need to be purchased and changed into boards of various specifications. Then, the wood needs to be left in the workshop for more than half a year to allow the wood to dry naturally and take shape. If any deformed, cracked or rotten wood is found during this period, it can only be discarded. In simple terms, a traditional rocking bed is a basic trapezoidal wooden frame, connected to four horizontal beams, also known as bed frame beams, and four bed frame slats are added between the four horizontal beams. Then, three longitudinal beams, also known as lintels, are used to connect the horizontal beams from the bottom crossbars. The three longitudinal beams are not directly connected to the horizontal beams, but each longitudinal beam is connected to a top support wood, which is then connected to each beam and fixed.

[0004] Install metal parts at the bottom of the longitudinal beams on the side, install the slider, and let the entire shaker shake back and forth on the slider base. Use screws and other connectors to nail the inclined bottom plate to each beam on the top of each beam, and use the stability of the triangle to strengthen the stability of the frame. The inclined bottom plate is fixed to the beams one by one with self-tapping screws by numerous narrow wooden strips. There are hundreds of screws alone. Add another layer of three-layer board on the bottom plate to level the bottom surface. Finally, apply paint ash layer by layer on the three-layer board to form a paint ash layer. Make a rifling strip or groove on the paint ash layer. After forming, let it stand for a period of time to allow the material to stabilize, and then install accessories such as the ore feeding trough and flushing sink before it can be assembled and connected with the shaker head for use.

[0005] It can be seen that the production process of traditional rocking tables is very complicated, the preparation time of wood is long, and the production technology is demanding. It is not possible for skilled craftsmen with high level of experience to do it.

[0006] The preparation of wood alone takes at least half a year, so the production cycle of wooden rocking tables is very long and the production cost is high, which limits the output of rocking table manufacturers and makes it unable to meet the needs of the market in time. Summary of the invention

[0007] In view of the above problems, the utility model proposes a high-ratio steel frame rocking table, which can overcome the limitations of material preparation and structural deficiencies of traditional rocking tables, shorten the manufacturing cycle, reduce the number of processes, reduce costs, and increase output, thereby overcoming the shortcomings of the prior art.

[0008] The high-resolution steel frame rocking bed proposed in the utility model has a trapezoidal frame, a lacquer layer, a ore feeding trough, a flushing trough and a bedside connecting piece, and is characterized in that the trapezoidal frame is composed of a trapezoidal frame made of steel and a plurality of crossbeams and longitudinal beams in the frame, the longitudinal beams are welded to the lower side of the crossbeams, a slider seat is welded to the lower side of the longitudinal beams, a pull strip is installed on the lower side of the crossbeam to adjust the flatness of the bed surface, a bottom plate is fixed on the upper side of the crossbeam, and a lacquer coating is provided on the bottom plate, and the bedside connecting piece is installed on the long side of the trapezoidal frame, and a rifling strip or a groove is formed on the lacquer coating.

[0009] The trapezoidal frame and the cross beam are welded in the same plane with rectangular frame steels with the same cross-sectional dimensions, and the longitudinal beam is welded to the lower side of the cross beam with channel steel and is perpendicular to it.

[0010] There are four cross beams and three longitudinal beams. Tie rods are installed on the lower sides of the two side cross beams. The two ends of the tie rods are fixed on the two ends of the cross beams. The midpoint is reversely ridden on the top rod. The top rod is installed on the middle longitudinal beam. The top rod has an adjusting nut for adjusting the tightness of the tie rod.

[0011] The two ends of the pull rod are provided with threads for matching with corresponding nuts to assist in adjusting the tightness of the pull rod.

[0012] There are four slider seats, each of which is welded to the lower side of the longitudinal beams on both sides with steel plates, and a mounting hole connected with the slider is opened on the slider seat.

[0013] The bottom plate is a large core plate, which is directly fixed on the upper side of the cross beam, and the bottom plate covers the entire trapezoidal frame.

[0014] The trapezoidal frame is provided with an edge board outside, and the edge board is higher than the trapezoidal frame, so as to facilitate the landing and construction of the paint and ash layer. After the paint and ash layer is formed, it is higher than or flush with the edge board.

[0015] Tie beams parallel to the longitudinal beams can be welded between the cross beams and kept in the same plane as the cross beams to enhance the strength of the entire trapezoidal frame.

[0016] The ore feeding trough and the water feeding trough are fixed on the upper side of the bed surface and on the oblique side of the trapezoidal frame.

[0017] The utility model is characterized in that the overall frame of the rocking bed is welded with square steel, channel steel and part of steel plate, and the upper side cancels the inclined bottom plate and three-layer plate of the traditional rocking bed, but uses a layer of large core plate with a thickness of about 16mm to lay at one time, thereby greatly reducing the workload. The traditional inclined bottom plate is fixed on the beam with self-tapping screws one by one by numerous narrow wooden strips, and there are hundreds of screws alone. In addition to leveling the bottom surface, it takes several skilled workers to work continuously for several days to complete it. After leveling, another layer of three-layer plate must be nailed before the paint ash coating can be applied on it, which is time-consuming, material-intensive and labor-intensive. After using the utility model, the bottom plate can be completed by laying only one layer of large core plate, without leveling, and the bottom plate can be completed and the paint ash layer can be applied in half a day.

[0018] Another notable feature of the present invention is that there is no need for a material preparation period, steel is not restricted by seasons and weather conditions, and the large core board is also a commercially available profile without seasonal and climatic constraints. Therefore, production can be organized all year round, and the production period is short. Generally, 3 to 5 steel frame rocking beds can be produced in the time of producing one wooden frame rocking bed. Therefore, the production cost is low and the production volume can be greatly increased.

[0019] Since the utility model has no material preparation period, there is no need to pile up raw materials, steel plates can be purchased as needed, and the capital turnover is fast, which creates relaxed operating conditions for production enterprises.

[0020] The steel frame structure of the invention has high strength, simple structure and strong anti-deformation ability. Production practice proves that the separation and enrichment ratio of the ore dressing machine is high, which is equivalent to or slightly higher than that of the wooden frame shaking table.

[0021] The wooden frame rocking bed is a mortise and tenon structure, and under the working condition of frequent shaking, its stability is worse than that of the steel frame rocking bed. Therefore, the utility model has a long service life and low maintenance cost.

[0022] In summary, the utility model overcomes the limitations of material preparation and structural deficiencies of traditional shaking tables, and achieves the invention objectives of shortening the manufacturing cycle, reducing the number of processes, reducing costs, and increasing output.

DETAILED DESCRIPTION

[0031] The utility model is further described below in conjunction with the accompanying drawings.

[0032] like Figure 1 As shown, the basic structure of the existing wooden frame rocking bed is as mentioned above, its main frame is a trapezoidal frame 5 made of wood, four bed frame beams 8 in the frame are connected and fixed to the trapezoidal frame by mortise and tenon joints, four bed frame slats 9 are fixed to the trapezoidal frame by screws, etc., three bed frame lintels 7 are cross-armed under the bed frame beams, and a thinner strip of wood is added on top as a top support wood 9 to contact the bed frame beams, the bed frame lintels, top support wood, and bed frame beams are generally fixed with screws or bolts, and the edging board 4 is generally made of iron plate or wooden board. The inclined bottom plate 3 is a significant feature of the traditional wooden frame rocking bed. It is made of wooden strips about 10mm thick and obliquely laid on the trapezoidal frame, bed frame beams and bed frame slats, and fixed with self-tapping screws. Almost every contact point needs a screw. A rocking bed needs about hundreds of screws to form a large number of triangular structures to ensure basic stability. A layer of three-layer board is laid on the bottom plate to fix and level it, and finally a paint ash layer 1 (also called paint ash coating) is applied to make a rifling strip or groove. Sliders, pull bars and slope adjustment mechanisms are installed under the bed, and there is a water tank for flushing the ore tank on the bed. The shaking tables made by the inventor of this application for many years are of this structure. Its advantage is that it can separate and enrich heavy minerals such as tin and tungsten. Mine re-selection plants purchase more and occupy a large market share in the local area. The disadvantages are as mentioned above, the most prominent of which is the long material preparation period, which takes more than half a year, a lot of capital occupation, high enterprise operating costs, high risks, long production cycle, and low output.

[0033] In the face of such problems, the utility model boldly proposes to replace the wooden frame structure with a steel frame structure. The inventor was also worried that there would be problems after the replacement. After all, the wooden frame rocking bed has a history of hundreds of years. This idea may have been tried by predecessors a long time ago. If it was successful, there would have been commercial products of steel frame rocking beds a long time ago.

[0034] After repeated manufacturing experiments, debugging and material selection comparison tests, as well as many years of production tests, it has been proved that the utility model is successful.

[0035] The specific structure and innovative features of the utility model are as follows: Figure 2-5 shown.

[0036] The trapezoidal frame 24 and the four cross beams 16 are welded with 40×80 mm square steel, eliminating the bed frame slats of the traditional wooden rocking bed, and the three longitudinal beams, that is, a middle longitudinal beam 17 and two side longitudinal beams 12 are welded with channel steel, eliminating the top support wood of the traditional bed.

[0037] The tie beam 15 is selected according to the specific situation. The tie beam is not a necessary component. Its function is only to enhance the anti-deformation ability of the frame. With its existence, this ability will be stronger. Without it, the overall anti-deformation ability of the frame can also meet the basic requirements.

[0038] Since the steel frame is welded from steel, its overall stability is stronger than that of the wooden frame with mortise and tenon joints when subjected to external forces. Therefore, it is no longer necessary to use an inclined bottom plate to form a triangular structure. Instead, a 16mm thick commercially available core board is directly laid in the trapezoidal frame and fixed with screws to form the paint layer 1. This greatly shortens the production time and saves a lot of material and labor costs.

[0039] The slider mechanism under the bed body is formed by welding four rectangular steel plates on the lower side of the longitudinal beams on both sides, which serve as the slider seat 11, and the mounting holes are opened on the seat. The setting of the tie rod 18 is basically the same as that of the wooden frame rocking bed. A steel bar is installed on the lower side of the two cross beams on the side. The two ends of the steel bar tie rod are threaded and pass through the jacks on the cross beams. Then, nuts are used to fix and assist in adjustment. The midpoint is located at the top rod 22 on the lower side of the middle longitudinal beam 17. The top rod uses a channel steel block welded on the middle longitudinal beam as the top rod seat 21. The upper half of the top rod is cylindrical and threaded, and the lower half is a square column inserted in the square hole of the top rod seat to prevent it from rotating, and locked with a cross pin or equipped with a spring to prevent it from slipping off. The threaded section is equipped with an adjusting nut 23. When the nut is turned, the top rod will move up and down to adjust the tightness of the tie rod. The end of the top rod can be made into a fork-shaped structure to prevent the tie rod from slipping off.

[0040] The bed head connector 20, edging plate (steel) 14, ore feeding trough 13, flushing trough 19, rocking bed head 28, motor 26, transmission belt 27, as well as the slider mechanism and slope adjustment mechanism under the bed are the same as those of the traditional rocking bed and will not be repeated here.

[0041] The parts and numbers not mentioned are as described above.
