Description

Technical Field

[0001] The utility model relates to the technical field of coal slime detection, in particular to a real-time coal slime water coarseness detection device based on multi-frequency excitation. Background Art

[0002] In the intelligent coal preparation process, sensors and detection systems are widely used, including sensors and detection systems for measuring flow, weight, concentration, interface, turbidity, pressure, liquid level, ash content, moisture, etc. Under ideal working conditions, the measurements of these sensors are accurate and effective. However, if some interference factors in the intelligent control of the washing process cannot be detected and avoided in time, the accuracy of the sensors and detection systems will be affected, which will in turn endanger the process system and control system, and ultimately lead to substandard washing products and low production efficiency.

[0003] For the treatment of coal slime water, poor control of the bottom flow pulp characteristics of the primary coal slime thickening tank will directly affect the subsequent flotation extraction effect of the final clean coal, including the coarseness phenomenon in the bottom flow of the primary coal slime thickening tank. The main sources of this coarseness phenomenon are the pre-washing desludging stage, the dilute medium de-mediation stage, the lump coal centrifugal dehydration stage, the arc screen and the centrifuge coarse cutting stage, etc. The coarse particles will be collected in the primary coal slime thickening tank. The bottom flow of the primary coal slime thickening tank is used as the flotation feed. If the "coarseness" phenomenon is not detected in time, it will greatly affect the flotation efficiency, tail coal ash content and flotation agent consumption, and at the same time destroy the pressing effect of the filter press system, so it needs to be solved urgently.

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] See also Figures 1 to 9 The utility model comprises a support frame 1, a cleaning component 2, a dissociation component 3, an identification component 4 and a rotating material transport component 5.

[0040] like Figure 1 and Figure 2 As shown, the support frame 1 includes a cleaning support plate 11, a dissociation support plate 12, an identification support plate 13, a rotation support plate 14, a flushing support plate 15 and a column 16. The column 16 is fixed to the ground by welding or expansion screws, and the column 16 is arranged vertically. Each support plate is welded and fixed to the column 16 in an interlaced manner from top to bottom along the axial direction of the column 16, and the surface of each support plate is arranged horizontally.

[0041] like Figure 1 and Figure 3 As shown, the cleaning assembly 2 is arranged below the cleaning support plate 11. The cleaning assembly 2 includes a scissor lift platform 21, a cleaning motor 22, a coupling 23, a rotary bearing 24, a stop rod 25, a flushing positioning plate 26, a flushing pipe 27, a rotating shaft 28 and a cleaning brush 29.

[0042] The base of the scissor lift platform 21 is fixed on the lower surface of the cleaning support plate 11, and the scissor lift platform 21 is lifted and lowered in the vertical direction. The base of the cleaning motor 22 is fixedly connected to the lower surface of the scissor lift platform 21, and the axial direction of the rotating shaft of the cleaning motor 22 is vertically downward. The rotating shaft of the cleaning motor 22 is connected to the rotating shaft 28 through a coupling 23, driving the rotating shaft 28 to rotate coaxially. A cleaning brush 29 is coaxially fixed to the bottom end of the rotating shaft 28. The cleaning brush 29 includes a plurality of brush rings 291 that are coaxial with the rotating shaft 28 and are nested equidistantly from the inside to the outside along the radial direction of the rotating shaft 28, and the diameter of each brush ring 291 increases successively. Bristles are arranged on the lower annular surface of each brush ring 291. Each brush ring 291 is connected to each other by three connecting strips 292 extending radially along the brush ring 291, and the three connecting strips 292 are arranged equidistantly along the circumference of the brush ring 291. A flow gap 293 is formed between adjacent brush rings 291 .

The long rod section of the stop rod 25 is arranged in the vertical direction, and the short rod section is arranged in the horizontal direction. In addition, a rotating bearing 24 coaxially sleeved on the shaft body of the rotating shaft 28 is fixedly connected to the end of the short rod section of the stop rod 25. The coupling 23 and the rotating bearing 24 realize double-point support for the rotating shaft 28, thereby improving the stability of the rotation of the rotating shaft 28. The stop rod 25 is fixedly connected to the outer ring of the rotating bearing 24. A flushing positioning plate 26 is welded to the other side of the outer ring of the rotating bearing 24, and the flushing positioning plate 26 is arranged horizontally. A flushing pipe 27 is also arranged on the flushing positioning plate 26, and each flushing pipe 27 is arranged on the flushing positioning plate 26 in sequence and equidistantly along the radial direction of the rotating bearing 24.

[0044] The water sprayed from each flushing nozzle has already converged before encountering the cleaning brush 29, and the radial intersection length along the brush ring 291 is greater than the radius of the cleaning brush 29. The water from the flushing nozzle can clean the bristles on the lower ring surface of the brush ring 291 through the flow gap 293. In this way, the cleaning brush 29 can be sprayed with clean water during the entire rotation process, thereby improving the cleaning effect of the stains attached to the bristles.

The dissociation assembly 3 includes a telescopic rod 31, a support rod 32, and a lifting sleeve 33. The telescopic rod 31 can be an electric push rod or a hydraulic cylinder. The base of the telescopic rod 31 is installed on the dissociation support plate 12 and is telescopic in the vertical direction.

It also includes a support seat, the upper end surface of the support seat is placed in parallel, and an ultrasonic dissociator 70 is arranged on the support seat. Three lifting sleeves 33 are vertically arranged on the bottom end surface of the support seat, and the telescopic end of the telescopic rod 31 and the front end of the support rod 32 are nested in the corresponding lifting sleeves 33. In this way, when the support seat is moved up and down, the stability of the movement can be improved, and the support seat is prevented from causing the ultrasonic dissociator 70 to slip due to tilt, thereby ensuring the smooth progress of the dissociation process.

[0046] like Figure 1 and Figure 6 As shown, the identification component 4 is located between the identification support plate 13 and the flushing support plate 15.

The water tank 41 is fixedly mounted on the lower plate surface of the identification support plate 13, and an outlet is provided at the bottom of the water tank 41, which is communicated with the flushing nozzle 42. The spraying area of ​​the flushing nozzle 42 is even with the pool mouth of the wastewater pool 44, so as to facilitate spraying clean water into the wastewater pool 44 for cleaning. The top opening of the wastewater pool 44 is in the shape of a trumpet with a large top and a small bottom. The spraying area of ​​the flushing nozzle 42 is located within the covering range of the top opening of the wastewater pool 44, which can prevent the clean water from spilling out. The bottom of the wastewater pool 44 is an inclined surface inclined to one side, and the outlet of the wastewater pool 44 is located on the lower side of the inclined surface, thereby ensuring convenient drainage.

[0047] like Figure 1 , Figure 7 , Figure 8 and Fig. 9 As shown, the rotating material transport assembly 5 is arranged below the rotating support plate 14 and mounted on the column 16. The rotating material transport assembly 5 includes a rotating motor 51, a driving gear 52, a first supporting shaft 53, a second supporting shaft 54, an axial bearing 55, a rotating sleeve 56, a flip motor 57, a supporting ring 58 and a clamping assembly 581.

[0048] The rotating sleeve 56 is coaxially sleeved on the column 16, and the first supporting shaft 53 and the second supporting shaft 54 ​​are coaxially nested in the rotating sleeve. The outer ring of the first supporting shaft 53 and the outer ring of the second supporting shaft 54 ​​are coaxially fixed to the inner cylinder surface of the rotating sleeve 56; the column 16 is nested on the outer ring of the first supporting shaft 53 and the outer ring of the second supporting shaft 54, and are coaxially fixed to each other. A bearing seat is provided below the rotating sleeve 56, and the axial bearing 55 is installed in the axial bearing seat. The upper surface of the axial bearing 55 is used to support the rotating sleeve 56.

[0049] The base of the rotating motor 51 is fixed on the lower plate surface of the rotating support plate 14, and the positive direction of the rotating shaft of the rotating motor 51 is vertically downward. A driving gear 52 is coaxially fixed to the rotating shaft of the rotating motor 51, and a driven gear is coaxially fixed to the outer side of the rotating sleeve 56. The driving gear 52 and the driven gear are in transmission meshing engagement, and the rotating motor 51 drives the rotating sleeve 56 to rotate.

[0050] The base of the flip motor 57 is fixedly connected to the outer surface of the rotating sleeve 56, and the two flip motors 57 are symmetrically arranged on both sides of the rotating sleeve 56, and the axial directions of the two flip motors 57 are arranged horizontally. The support ring 58 is fixedly connected to the rotating shaft of the flip motor 57. The upper surface of the upper ring surface of the support ring 58 is used to clamp the clamping assembly 581 of the material receiving funnel 60. The clamping assembly 581 includes two guide grooves 5811 symmetrically arranged on the upper ring surface of the support ring 58, and a slider 5813 is slidably arranged in the guide groove 5811. A semicircular clamp 5812 is arranged at the front end of the slider 5813. The two clamps 5812 moving toward each other are surrounded by each other to form a cylindrical clamping cavity that can be clamped on the outside of the material receiving funnel 60. A reset spring 5814 is arranged at the tail of the slider 5813 to push the two sliders 5813 to move toward each other.

[0051] The receiving funnel 60 is in the shape of a flat-bottomed round basin, and the bottom is a hollow mesh structure. The diameter of the leakage hole is usually smaller than the particle size of the coal slime according to the actual situation to prevent the coal slime from falling.

[0052] The ultrasonic dissociator 70 has a dissociation tank capable of accommodating the receiving funnel 60, and the dissociation tank is filled with a dissociation liquid.

[0053] The detection process is as follows:

[0054] When the roughing detection is performed, the rotating material transport component 5 drives the driving gear 52 through the rotating motor 51 to rotate the receiving funnel 60 installed on the rotating sleeve 56 to between the cleaning brush 29 and the ultrasonic dissociator 70. At this time, the feeding pipe located on one side of the receiving funnel 60 discharges the material through the electromagnetic valve for a period of time, and then the electromagnetic valve is closed, and the coal slime inside the receiving funnel 60 is spread flat on the bottom of the receiving funnel 60. The telescopic rod 31 drives the ultrasonic dissociator 70 to rise until the coal slime at the bottom of the receiving funnel 60 is completely immersed in the dissociation water in the ultrasonic dissociator 70, and the ultrasonic dissociator 70 is started for dissociation. The fine sticky materials in the coal slime are fully dissociated under the action of the high-frequency excitation wave, and then the cleaning brush 29 is extended into the receiving funnel 60 driven by the scissor lift platform 21. Under the action of the cleaning motor 22, the cleaning brush 29 drives the materials in the receiving funnel 60 to rotate to accelerate the separation; then the fine mud materials are accelerated to pass through the receiving funnel 60 and enter the ultrasonic dissociator 70. After the fine mud material in the receiving hopper 60 is fully dissociated for a period of time, the electric lifting rod 31 drives the ultrasonic dissociator 70 to descend, the material in the receiving hopper 60 is separated from the dissociation water, and then the flushing nozzle starts to spray water, and the cleaning brush 29 also keeps rotating; the water sprayed from the flushing nozzle washes away the fine coal adhering to the bristles of the cleaning brush 29 through the flow gap 293; at the same time, the fine coal in the receiving hopper 60 is further washed away, and the fine coal on the coal mud is washed away to obtain coal particles. Then the receiving hopper 60 is rotated between the camera 43 and the wastewater tank 44 by the rotating motor 51; then the camera 43 takes an image, and through the image recognition and processing technology, the coal particle size is identified and counted, and the coal particle size is realized online monitoring. After identification, the flip motor 57 drives the support ring 58 to rotate 180 degrees, and the material in the receiving hopper 60 is dumped into the wastewater tank 44, and then the flushing nozzle 42 under the water tank 41 flushes and cleans the bottom of the receiving hopper 60 until the receiving hopper 60 is rinsed clean. The cleaned receiving hopper 60 is used for the next receiving identification link. The material in the wastewater tank 44 is leaked out through the outlet at the bottom to carry out regular cleaning.
