[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this disclosure pertains. The terms used herein in the specification of this disclosure are intended only to describe specific embodiments and are not intended to limit this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0032] like Figures 1 to 3 As shown, it is a vibrating screen device 10 with screen monitoring according to an embodiment of the present disclosure, including a vibrating screen mechanism 100, a separation tank mechanism 200 and a screen monitoring mechanism 300; the vibrating screen mechanism 100 includes a vibrating screen body 110, a screen 120 and a vibrating screen transducer 130, the screen 120 is installed in the vibrating screen body 110, the screen 120 is used to screen and separate foreign matter and large particles of impurities in the material, the vibrating screen transducer 130 is installed in the vibrating screen body 110, the vibrating screen transducer 130 is used to generate ultrasonic frequency to vibrate the screen 120, so that the mesh of the screen 120 is not easily clogged after vibration.

[0033] Furthermore, the separation tank mechanism 200 includes a diverter tank body 210, a discharge pipe 220, a diverter pipe 230 and a flap valve assembly 240. The diverter tank body 210 is provided with a material feed port 2101 and a material passage 2102 that are connected to each other. The material feed port 2101 is connected to the discharge port of the vibrating screen body 110, and the material passage 2102 is connected to the discharge pipe 220 and the diverter pipe 230 respectively. The flap valve assembly 240 is installed on the diverter tank body 210, and the flap valve assembly 240 is used to switch the material passage 2102 to be connected to the discharge pipe 220 or the diverter pipe 230. ; The screen monitoring mechanism 300 includes a material monitoring component 310 and a current monitoring component 320. The monitoring end of the material monitoring component 310 is arranged below the material feed port 2101 to monitor the material discharge rate and send out an alarm signal. The material monitoring component 310 is used to monitor the material discharge rate. The control end of the material monitoring component 310 is electrically connected to the flap valve component 240. The monitoring end of the current monitoring component 320 is connected to the output end of the vibrating screen transducer 130. The control end of the current monitoring component 320 is electrically connected to the flap valve component 240.

[0034] In this embodiment, the monitoring end of the current monitoring component 320 can monitor the working condition of the vibrating screen transducer 130 and send out an alarm signal. The working condition of the vibrating screen transducer 130 can be a change in the current, voltage or power of the vibrating screen transducer 130. When the screen 120 is damaged, the vibration frequency of the screen 120 decreases, and the vibrating screen transducer 130 increases the output current to increase the frequency of the ultrasonic frequency vibrating screen 120. After the current monitoring component 320 detects the change in the current of the vibrating screen transducer 130, the current monitoring component 320 sends out an alarm signal. At the same time, the current monitoring component 320 controls the flap valve component 240 to switch the feed channel 210. 2 is connected to the diversion pipe 230, so that the unqualified materials that have not been screened and separated by the screen 120 in the vibrating screen body 110 enter the diversion tank 210, and then enter the diversion pipe 230 after passing through the diversion tank 210; when the screen 120 is damaged, the material entering the material feed port 2101 from the vibrating screen body 110 increases, and the monitoring end of the material monitoring component 310 detects an increase in the material discharge rate, and the material monitoring component 310 sends an alarm signal. At the same time, the material monitoring component 310 controls the material passage 2102 of the flap valve component 240 to be connected to the diversion pipe 230, so that the unqualified materials that have not been screened and separated by the screen 120 enter the diversion pipe 230.

[0035] In the above-mentioned vibrating screen device 10 with screen monitoring, the current monitoring component 320 monitors the damage of the screen 120 by detecting the change in the current of the vibrating screen transducer 130, and the monitoring end of the material monitoring component 310 monitors the damage of the screen 120 by detecting the increase in the material feeding rate, so that the current monitoring component 320 and the material monitoring component 310 can simultaneously monitor the damage of the screen 120, reducing the frequency of manual inspection, thereby timely discovering the damage of the screen and processing it, reducing the generation of unqualified materials, and thus improving production efficiency; the current monitoring component 320 and the material monitoring component 310 control the flap valve component 240 to switch the material flow channel 2102 to connect to the diverter pipe 230, so that the unqualified materials that have not been screened and separated by the screen 120 are separated and enter the diverter pipe 230, avoiding the unqualified materials from mixing into the qualified materials, reducing the secondary processing cost of material rework, and thus improving production efficiency. When the current monitoring component 320 and the material monitoring component 310 detect that the screen is damaged, they respectively send out alarm signals, preventing the inability to effectively isolate unqualified materials when a single monitoring device fails, and making it convenient for operators to check and repair the current monitoring component 320 and the material monitoring component 310.

[0036] like Figure 2As shown, in one embodiment, the material monitoring component 310 includes a speed measuring impeller 311, a monitoring control box 312 and a first alarm 313. The speed measuring impeller 311 is arranged below the material feed port 2101, and the monitoring control box 312 is electrically connected to the speed measuring impeller 311. The monitoring control box 312 is used to monitor the rotational speed of the speed measuring impeller 311. The signal output end of the monitoring control box 312 is connected to the first alarm 313, and the control end of the monitoring control box 312 is electrically connected to the flap valve assembly 240. In this embodiment, when the screen 120 is damaged, the amount of material entering the material feed port 2101 from the vibrating screen body 110 increases, and the material falls on the speed measuring impeller 311, causing the speed of the speed measuring impeller 311 to increase. The monitoring control box 312 monitors the acceleration of the speed measuring impeller 311 and transmits the electrical signal to the first alarm 313. The first alarm 313 sends out an audible and visual alarm signal, so that the operator can promptly discover that the screen 120 is damaged. The monitoring control box 312 outputs the control signal to the flap valve assembly 240, and the flap valve assembly 240 switches the material flow channel 2102 to connect to the diverter pipe 230, so that the unqualified materials that have not been screened and separated are separated and enter the diverter pipe 230, thereby avoiding the unqualified materials that have not been screened and separated from being mixed into the qualified materials.

[0037] like Figure 3 As shown, in one embodiment, the velocity measuring impeller 311 is eccentrically disposed below the material feed inlet 2101, and the width of the blades of the velocity measuring impeller 311 is greater than the diameter of the material feed inlet 2101. In this embodiment, the velocity measuring impeller 311 is eccentrically disposed below the material feed inlet 2101, so that the blades of the velocity measuring impeller 311 correspond to the lower portion of the material feed inlet 2101. When the material falls from the material feed inlet 2101, the material lands on the blades of the velocity measuring impeller 311. The width of the blades of the velocity measuring impeller 311 is greater than the diameter of the material feed inlet 2101, which increases the amount of contact between the falling material and the blades of the velocity measuring impeller 311 and reduces the amount of falling material flowing out from locations outside the blades of the velocity measuring impeller 311, thereby causing inaccurate velocity measurement by the velocity measuring impeller 311.

[0038] like Figure 2As shown, in one embodiment, the current monitoring component 320 includes a transducer control box 321 and a second alarm 322, the monitoring end of the transducer control box 321 is connected to the vibrating screen transducer 130, the control end of the transducer control box 321 is connected to the flap valve assembly 240, and the second alarm 322 is electrically connected to the signal output end of the transducer control box 321. In this embodiment, when the screen 120 is damaged, the transducer control box 321 detects that the output current of the vibrating screen transducer 130 increases, and the transducer control box 321 transmits an electrical signal to the second alarm 322. The second alarm 322 emits an audible and visual alarm, allowing the operator to promptly discover that the screen 120 is damaged. The output control signal of the transducer control box 321 is transmitted to the flap valve assembly 240, so that the flap valve assembly 240 promptly switches the material passage 2102 to connect to the diverter pipe 230, thereby separating unqualified materials and entering the diverter pipe 230, thereby preventing unqualified materials that have not been screened and separated from being mixed with qualified materials. The combined action of the first alarm 313 and the second alarm 322 prevents the failure of a single monitoring device to effectively isolate unqualified materials, thereby ensuring the effectiveness of monitoring the damage to the screen 120. When the first alarm 313 or the second alarm 322 fails, the current monitoring assembly 320 or the material monitoring assembly 310 can be checked based on the location where no alarm signal is generated.

[0039] like Figure 2 and Figure 3 As shown, in one embodiment, the flap valve assembly 240 includes a flip plate 241, a rotating shaft 242 and a flip motor 243. The main body of the rotating shaft 242 is arranged in the material transfer channel 2102. The flip plate 241 is fixedly connected to the rotating shaft 242. The flip plate 241 is used to switch the material transfer channel 2102 to connect to the discharge pipe 220 or the diversion pipe 230. The flip motor 243 is fixed to the outside of the diversion tank body 210. The output end of the flip motor 243 is connected to one end of the rotating shaft 242. The control end of the flip motor 243 is electrically connected to the current monitoring component 320 and the material monitoring component 310 respectively. In this embodiment, when the flip motor 243 is started, the rotating shaft 242 is controlled to rotate, and the rotating shaft 242 drives the flip plate 241 to rotate. When the flip plate 241 abuts against the inner wall of the diversion tank body 210 in the vertical direction to open the discharge pipe 220 and close the diversion pipe 230, the material is discharged normally. When the flip plate 241 abuts against the inner wall of the diversion tank body 210 in the horizontal oblique direction to open the diversion pipe 230 and close the discharge pipe 220, the material falls along the inclined flip plate 241 into the diversion pipe 230. The material is switched into the diversion pipe 230 by the flip plate 241, which avoids the mixing of unqualified materials that have not been screened and separated into qualified materials, reduces the secondary processing process of the material, and thus improves production efficiency.

[0040] like Figure 2 and Figure 3As shown, in one embodiment, the flap valve assembly 240 also includes a first position sensor 244 and a second position sensor 245. The first position sensor 244 is arranged on the inner wall of the diversion tank body 210 adjacent to the discharge pipe 220, and the first position sensor 244 is used to detect the position of the flip plate 241 away from one end of the rotating axis 242. The second position sensor 245 is arranged on the inner wall of the diversion tank body 210 adjacent to the diversion pipe 230, and the second position sensor 245 is used to detect the position of the flip plate 241 away from one end of the rotating axis 242. In this embodiment, the first position sensor 244 and the second position sensor 245 can detect whether the flip plate 241 is in place away from the end of the rotating shaft 242. The first position sensor 244 detects whether the flip plate 241 completely blocks the discharge pipe 220, and the second position sensor 245 detects whether the flip plate 241 blocks the diversion pipe 230, thereby preventing the material from leaking at the position of the blocked discharge pipe 220 or the blocked diversion pipe 230, avoiding the mixing of unqualified materials with qualified materials, and reducing material rework.

[0041] like Figure 3 As shown, in one embodiment, the discharge pipe 220 is connected to the bottom of the diverter tank 210 and extends vertically downward. The diverter pipe 230 is connected to the side wall of the diverter tank 210 and extends obliquely downward. In this embodiment, the discharge pipe 220 is connected to the bottom of the diverter tank 210, allowing the material to fall smoothly. The diverter pipe 230 is connected to the side wall of the diverter tank 210, so that the diverter pipe 230 does not block the falling material, thereby preventing the diverter pipe 230 from affecting the material discharge speed.

[0042] like Figure 2 As shown, in one embodiment, the separation tank mechanism 200 further includes a material collection assembly 250, which includes a first ton bag 251 and a second ton bag 252. The first ton bag 251 is connected to the discharge port of the discharge pipe 220, and the second ton bag 252 is connected to the discharge port of the diversion pipe 230. In this embodiment, the first ton bag 251 is used to collect qualified materials, and the second ton bag 260 is used to collect unqualified materials. The collection of the first ton bag 251 and the second ton bag 252 facilitates the transportation of the collected materials and the feeding and processing of the materials in subsequent processes.

[0043] like Figure 1As shown, in one embodiment, the vibrating screen mechanism 100 further includes a feed pipe 140, one end of which is connected to the discharge port of the vibrating screen body 110, and the outlet end of the feed pipe 140 is connected to the material feed port 2101. The outlet end of the feed pipe 140 is a tapered structure. In this embodiment, the feed pipe 140 is used to connect the vibrating screen body 110 with the diversion tank 210, so that the material can smoothly enter the feed channel 2102 from the material feed port 2101. The width of the outlet end of the feed pipe 140 is reduced, so that the width of the material entering the material feed port 2101 from the outlet end of the feed pipe 140 is reduced, so that the material can accurately fall on the speed measuring impeller 311, thereby improving the accuracy of the speed measuring impeller 311 in detecting the material discharge rate.

[0044] like Figure 1 As shown, in one embodiment, the vibrating screen mechanism 100 further includes a coarse material pipe assembly 150, which includes a foreign material pipe 151 and a foreign material box 152. The feed port of the foreign material pipe 151 is located above the screen 120, and the discharge port of the foreign material pipe 151 is connected to the foreign material box 152. In this embodiment, when the material enters the vibrating screen body 110 and the screen 120 screens and separates the material, large pieces of material and foreign matter are screened and separated above the screen 120. The large pieces of material and foreign matter move to the feed port of the foreign material pipe 151 during vibration, so that the large pieces of material and foreign matter are collected in the foreign material box 152 through the foreign material pipe 151, which facilitates the processing of the large pieces of material and foreign matter.

[0045] Compared with the prior art, the present disclosure has at least the following advantages:

[0046] 1. In the vibrating screen device 10 with screen monitoring, the current monitoring component 320 monitors screen 120 damage by detecting changes in the current of the vibrating screen transducer 130, and the monitoring end of the material monitoring component 310 monitors screen 120 damage by detecting an increase in the material discharge rate. This allows the current monitoring component 320 and the material monitoring component 310 to simultaneously monitor screen 120 damage, reducing the frequency of manual inspections, thereby promptly detecting screen damage and handling it, reducing the generation of unqualified materials, and thereby improving production efficiency.

[0047] 2. The flap valve assembly 240 is controlled by the current monitoring assembly 320 and the material monitoring assembly 310 to switch the material passage 2102 to connect to the diversion pipe 230, so that unqualified materials that have not been screened and separated by the screen 120 are separated and enter the diversion pipe 230, avoiding unqualified materials from mixing with qualified materials, reducing the secondary processing cost of reworking the materials, and thus improving production efficiency.

[0048] 3. When the current monitoring component 320 and the material monitoring component 310 detect that the screen is damaged, they respectively send out alarm signals, thereby preventing the failure of a single monitoring device to effectively isolate unqualified materials, and facilitating the operator to check and repair the current monitoring component 320 and the material monitoring component 310.

[0049] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the disclosed patent shall be determined by the appended claims.
