Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically to a high-precision desliming arc screen. Background Technology

[0002] In the mining industry, especially in the coal washing and processing sector, the desliming arc screen is one of the commonly used key pieces of equipment. It is mainly used for the separation and discharge of media and waste liquid during the coal mining process. However, there are still some problems with the actual use of the current desliming arc screen.

[0003] When used for a long time, the arc screen surface of the desliming arc screen is prone to clogging, resulting in desliming and screening interruptions and poor separation accuracy. In addition, the feeding operation is often completed by manually pouring the material into the desliming arc screen, which can easily lead to uneven feeding and material stacking. This will affect the processing effect of the arc screen plate on the material and affect the processing efficiency. Based on this, we propose a new type of high-precision desliming arc screen. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision desliming arc screen to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision desliming arc screen, comprising a desliming arc screen body, wherein an ultrasonic generator, a PLC controller, and a material pump are sequentially installed on the outer wall of the desliming arc screen body; an arc screen plate is installed inside the desliming arc screen body, and transducers are uniformly installed on the top of the arc screen plate; a material collection chamber matching the material pump is provided inside the desliming arc screen body at one end of the arc screen plate; a diversion guide shell is uniformly arranged inside the desliming arc screen body above the arc screen plate; a screw feeder is uniformly installed at one end of the desliming arc screen body, and a docking feed port connected to the diversion guide shell is provided at the output end of the screw feeder; a second stepper motor is installed on one side of the desliming arc screen body, and a stirring shaft is connected to the output end of the second stepper motor; separation blades matching the diversion guide shell are uniformly arranged on the stirring shaft.

[0006] Preferably, both the desliming arc screen body and the screw feeder are uniformly welded with fixed supports, and the bottom of the fixed supports is uniformly provided with screw holes, so that the desliming arc screen body and the screw feeder can be assembled and fixed in a suitable operating position by screws and screw holes on the fixed supports, thereby improving the stability of the device during operation.

[0007] Preferably, the outer wall of the arc-shaped screen plate is provided with a Teflon non-stick layer, and both sides of the desliming arc-shaped screen body are fixed with side reinforcement arms, which improves the anti-sticking and wear-resistant effect of the arc-shaped screen plate.

[0008] Preferably, the input end of the pump is connected to the bottom end of the material collection chamber, and the output end of the pump is provided with a flange.

[0009] Preferably, there are three of each of the diversion guide shells and the screw feeder, and the diversion guide shells are arranged at equal intervals at the top of the inside of the desliming arc screen.

[0010] Preferably, the input end of the screw feeder is provided with a feeding trough, and the bottom end of the diversion guide shell is connected to the interior of the arc-shaped screen plate.

[0011] Preferably, a first stepper motor is installed at the bottom of the screw feeder, and a feeding screw is connected inside the screw feeder at the output end of the first stepper motor, so as to facilitate the realization of automated and uniform feeding function.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The high-precision desliming arc screen has optimized its performance by installing an arc screen plate, etc. The coal material added into the desliming arc screen body will jump on the screen surface of the arc screen plate. The large-sized and heavy coal particles and medium particles slide slowly due to inertia, while the fine medium and residual waste liquid will be discharged through the screen holes of the arc screen plate. The arc screen surface design can also allow the material to stay for a longer time, further promoting the desliming and screening of coal. In addition, when the ultrasonic generator installed on the desliming arc screen body is turned on, it will convert electrical energy into high-frequency energy, and then convert it into ultrasonic vibration through the transducer. Through the contact between the radiation surface of the transducer and the arc screen plate, the high-frequency ultrasonic vibration will make the large particles on the arc screen plate into a suspended state, thus avoiding the clogging of the mesh. It solves the problem of low screening efficiency caused by screen hole clogging during long-term use, as well as the problem of poor desliming and some medium not being able to pass through the screen hole in time and being discharged with the coal. Thus, the device achieves the advantage of high-precision desliming.

[0014] (2) This high-precision desliming arc screen optimizes its structure by installing screw feeders, etc. On the one hand, the user pours the coal to be processed into the feeding troughs connected to the input ends of the three screw feeders, and then the feeding screws inside the screw feeders automatically and evenly send the coal to the three corresponding diversion guide shells. Then, the three diversion guide shells disperse the material onto the arc screen plate, solving the problem of poor desliming and screening effect caused by material stacking. Moreover, the uniform and automatic feeding also ensures that the arc screen plate is in a suitable position. The appropriate material handling conditions avoid the problem of poor processing effect of the arc screen plate caused by too much or too little material, and achieve efficient screening effect. When the automated feeding structure feeds the material upward, it will also pre-separate and discharge some liquid and waste inside the coal mine material. On the other hand, the second stepper motor is started to drive the stirring shaft to rotate. The separation fan blades on the stirring shaft, which are distributed inside the three diversion guide shells, will break up and break the material entering the diversion guide shell, so as to prevent the material from piling up and sticking together and interfering with the subsequent desliming and screening effect.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-4An embodiment of this utility model is provided: a high-precision desliming arc screen, including a desliming arc screen body 6, an ultrasonic generator 3, a PLC controller 4 and a material pump 11 are sequentially installed on the outer side wall of the desliming arc screen body 6, an arc screen plate 9 is installed inside the desliming arc screen body 6, a transducer 13 is uniformly installed on the top of the arc screen plate 9, and a material collection chamber 12 matching the material pump 11 is provided inside the desliming arc screen body 6 at one end of the arc screen plate 9.

[0022] During use, the coal material added to the inside of the desliming arc screen body 6 will jump and move on the screen surface of the arc screen plate 9. Larger coal particles and heavier media particles slide slowly due to inertia, while fine media and residual waste liquid will be discharged through the screen holes of the arc screen plate 9. The arc screen surface design also allows the material to stay for a longer time, further promoting the desliming and screening of coal. In addition, when the ultrasonic generator 3 installed on the desliming arc screen body 6 is turned on, it will convert electrical energy into high-frequency energy, and then convert it into ultrasonic vibration through the transducer 13. Through the contact between the radiation surface of the transducer 13 and the arc screen plate 9, the high-frequency ultrasonic vibration will make the large particles on the arc screen plate 9 into a suspended state, thus avoiding clogging of the mesh. This solves the problem of low screening efficiency caused by screen hole clogging during long-term use, as well as the problems of poor desliming and some media not being able to pass through the screen holes in time and being discharged with the coal. Thus, the device achieves the advantage of high-precision desliming.

[0023] The inside of the desliming arc screen body 6 above the arc screen plate 9 is uniformly provided with a diversion guide shell 15. A screw feeder 1 is uniformly installed at one end of the desliming arc screen body 6. The output end of the screw feeder 1 is provided with a docking feed port 7 that is connected to the diversion guide shell 15.

[0024] The outer wall of the arc-shaped screen plate 9 is provided with a Teflon non-stick layer, and both sides of the arc-shaped screen body 6 are fixed with side reinforcement arms 8, which improves the anti-sticking and wear-resistant effect of the arc-shaped screen plate 9.

[0025] The screw feeder 1 has a feeding trough 17 at its input end, and the bottom of the diversion guide shell 15 is connected to the inside of the arc screen plate 9.

[0026] The bottom of the screw feeder 1 is equipped with a first stepper motor 2, and the output end of the first stepper motor 2 is connected to the internal feeder screw of the screw feeder 1, which facilitates the realization of automated and uniform feeding function.

[0027] There are three of each of the diversion guide shell 15 and the screw feeder 1. The diversion guide shell 15 is arranged at equal intervals at the top of the inside of the desliming arc screen body 6.

[0028] In use, the user pours the coal material to be processed into the feeding trough 17 connected to the input end of the three screw conveyors 1. Then, the feeding screw inside the screw conveyor 1 automatically and evenly feeds the coal material upward into the three corresponding diversion guide shells 15. The material is then dispersed and guided onto the arc screen plate 9 through the three diversion guide shells 15. This solves the problem of poor desliming and screening effect caused by material stacking. The uniform and automatic feeding also ensures that the arc screen plate 9 is in a suitable material processing state, avoiding the problem of poor processing effect caused by too much or too little material. This achieves a high-efficiency screening effect. When the automatic feeding structure feeds upward, it also pre-separates and discharges some of the liquid and waste inside the coal material.

[0029] A second stepper motor 10 is installed on one side of the desliming arc screen body 6. The output end of the second stepper motor 10 is connected to a stirring shaft 14. Separating fan blades 16 that match the diversion guide shell 15 are evenly arranged on the stirring shaft 14.

[0030] Fixed supports 5 are evenly welded on both the desliming arc screen body 6 and the screw feeder 1. The bottom of the fixed supports 5 is evenly provided with screw holes, which makes it easy to assemble and fix the desliming arc screen body 6 and the screw feeder 1 in a suitable operating position by passing screws through the screw holes on the fixed supports 5, thereby improving the stability of the device during operation.

[0031] When in use, the second stepper motor 10 is started to drive the stirring shaft 14 to rotate, so that the separation fan blades 16 distributed on the stirring shaft 14 inside the three diversion guide shells 15 will break up and separate the material entering the diversion guide shell 15, so as to avoid the material from piling up and sticking together and interfering with the subsequent desliming and screening process.

[0032] The input end of the pump 11 is connected to the bottom end of the material collection chamber 12, and the output end of the pump 11 is provided with a flange.

[0033] In this embodiment, when in use: With an external power supply, the user first assembles and fixes the desliming arc screen body 6 and the screw feeder 1 in a suitable operating position using screws and the screw holes on the fixing bracket 5, improving the stability of the device during operation. Next, the user pours the coal to be processed into the feeding troughs 17 connected to the input ends of the three screw feeders 1. Then, the feeding screws inside the screw feeders 1 automatically and evenly deliver the coal upwards to the three corresponding diversion guide shells 15. Finally, the three diversion guide shells 15 disperse the material into the arc screen. The curved screen plate 9 solves the problem of poor desliming and screening effect caused by material stacking. Uniform automated feeding also ensures that the curved screen plate 9 is in a suitable material handling state, avoiding the problem of poor processing effect caused by too much or too little material, thus achieving efficient screening. When the automated feeding structure feeds upwards, it also pre-separates and discharges some liquid and waste material inside the coal mine material. Simultaneously, the second stepper motor 10 is started, driving the stirring shaft 14 to rotate, causing the stirring shaft 14 to rotate, corresponding to the three diversion guide shells 15 distributed on the three diversion guide shells 15. The internal separating fan blades 16 break up and segment the material entering the diversion and guiding shell 15, preventing the material from piling up and sticking together, which would interfere with the subsequent desliming and screening process. Furthermore, the coal material added to the desliming arc screen body 6 will jump and move on the screen surface of the arc screen plate 9. Larger and heavier coal particles and media particles slide slowly due to inertia, while fine media and residual waste liquid will be discharged through the screen holes of the arc screen plate 9. The arc screen surface design also allows the material to remain for a longer time, further promoting the desliming and screening process of the coal. Additionally… When the ultrasonic generator 3 installed on the arc screen body 6 is turned on, it converts electrical energy into high-frequency energy, which is then converted into ultrasonic vibration through the transducer 13. Through the contact between the radiation surface of the transducer 13 and the arc screen plate 9, the high-frequency ultrasonic vibration causes large particles on the arc screen plate 9 to be suspended, thus avoiding clogging of the mesh. This solves the problems of low screening efficiency caused by screen hole clogging during long-term use, as well as poor desliming and some media not being able to pass through the screen holes in time and being discharged with the coal. As a result, the device achieves the advantage of high-precision desliming.
