Technical Field

[0001] The utility model belongs to the technical field of vibrating screens, and in particular relates to a vibrating screen mesh damage monitoring device. Background Art

[0002] Vibrating screen is a widely used industrial screening equipment, which uses vibration to grade and screen materials. The vibrating screen consists of dust cover, screen frame, mesh, screen, discharge port, base, vibration motor and other parts. The vibration motor generates multi-plane vibration, so that the material flows evenly on the screen surface and is separated through the screen.

[0014] The following will illustrate the implementation methods of the utility model in conjunction with the drawings in the specification. It should be noted that the implementation methods involved in this specification are not exhaustive and do not represent the only implementation methods of the utility model. The following corresponding embodiments are only for the purpose of clearly illustrating the utility model content of the utility model patent, and are not intended to limit its implementation methods. For ordinary technicians in this field, different forms of changes and modifications can be made on the basis of the description of this embodiment. All obvious changes or modifications that belong to the technical concept and utility model content of the utility model are also within the scope of protection of the utility model.

[0015] like Figure 1 and Figure 4 As shown, an embodiment of the present application provides a vibrating screen damage monitoring device, including an identification ball (not shown in the figure), a ball blocking net 21 and a detector 22.

[0016] Among them, Figure 1 and Figure 2 As shown, the vibrating screen includes a dust cover 110 , a screen frame 120 , a base 130 and a vibrating motor 140 .

[0017] The cross section of the screen frame 120 is circular, the bottom has a frame bottom, and the whole is cylindrical. A dust cover 110 is arranged on the top, and a feed port is arranged on the dust cover 110.

[0018] A machine base 130 is disposed at the lower side of the screen frame 120 , and a plurality of springs 150 are disposed therebetween. A vibration motor 140 is disposed on the machine base 130 , and the vibration motor 140 is connected to the frame bottom of the screen frame 120 .

[0019] like Figure 2As shown, the screen frame 120 is provided with N layers of grids 121, and N layers of screens (not shown in the figure) are arranged through the N layers of grids 121. The screen frame 120 is provided with N discharge parts 122 corresponding to the N layers of screens, and a discharge part 122 corresponding to the bottom of the screen frame 120, a total of N+1 discharge parts 122, N is an integer greater than or equal to 1, Figure 2 Where N=2.

[0020] A plurality of identification balls are placed on each layer of the sieve, and the diameter of the identification balls is larger than the mesh aperture of the sieve where the identification balls are placed.

[0021] like Figure 3 and Figure 4 As shown, the discharge portion 122 includes an outer shell 122a, which is connected to the screen frame 120. The interior of the outer shell 122a is a material cavity, and the lower side of the outer shell 122a forms a discharge port 122b in the up and down directions. Among the multiple discharge portions 122, the discharge ports 122b of the remaining discharge portions 122 except the topmost discharge portion are all provided with a ball blocking net 21, and the upper side of the outer shell 122a also forms an installation port 122c opposite to the ball blocking net 21 up and down, and the installation port 122c is provided with a detector 22 corresponding to the ball blocking net 21 up and down, and the ball blocking net 21 is used for allowing the same layer of material to pass through and retaining identification balls. The same layer of material refers to the material left by the same layer of screen.

[0022] In order to prevent the identification balls on the uppermost screen from being discharged from the discharging part of the same layer, the discharging port 122b of the uppermost discharging part is also provided with a ball blocking net 21.

[0023] During monitoring, the controller uses the detector 22 to detect in real time whether there is an identification ball on the corresponding ball blocking net 122c. If there is, it means that the screen is damaged. The principle is: if the ball blocking net is damaged, the identification ball on it will fall to the lower layer and enter the lower discharge part 122. If the detector 22 of the lower discharge part 122 detects the identification ball on the upper layer, it means that the screen is damaged.

[0024] like Figure 5 As shown, in one embodiment, the vibrating screen has only one layer of screen and two discharge parts. The first layer of the discharge part and the screen are on the same layer and no detector is set. The second layer of the discharge part is set with a detector. During monitoring, if the detector detects that there is an identification ball on the corresponding ball blocking net, the screen is damaged, and then an alarm is processed, such as prompting that the screen is damaged on the display screen and beeping at the same time.

[0025] In another embodiment, the vibrating screen has multiple layers of screens. In order to further locate the damaged screens, the identification balls on different screens have different identification features. In this embodiment, the identification feature is the color of the identification balls, and the identification balls on different screens have different colors.

[0026] like Figure 6 As shown, taking two layers of screens as an example, there are three discharging parts, the first discharging part is on the same layer as the first layer of screens, the second discharging part is on the same layer as the second layer of screens, and the third discharging part is on the same layer as the inner bottom surface of the screen frame. The first discharging part is not provided with a detector, and the second and third discharging parts are provided with detectors. The first layer of screens is used to place red balls, and the second layer of screens is used to place yellow balls, that is, the screen where the red balls are initially located is the first layer of screens, and the screen where the yellow balls are initially located is the second layer of screens. The detector uses a chromatograph or a camera. When a camera is selected, the controller performs detection through an image recognition algorithm.

[0027] During monitoring, if the detector detects the presence of an identification ball on the corresponding ball-blocking net, the damaged screen can be located based on the identification features of the detected identification ball.

[0028] For example, if a red ball is detected by the detector of the second-layer discharge part, it means that the red ball has fallen from the broken hole of the first layer of the screen to the second layer, which means that the first layer of the screen is a broken screen.

[0029] For example, if a red ball is detected by the detector of the third-layer discharge part, it means that the red ball has fallen from the broken openings of the first and second layers of the sieve to the third layer, which means that both the first and second layers of the sieve are broken.

[0030] After the damaged screen is located, an alarm is processed, such as prompting the number of the damaged screen on the display screen and beeping at the same time.

[0031] In order to avoid false detection, if the detector detects a ball on the same layer, the ball will be ignored. For example, if the detector detects a yellow ball on the second layer of the discharge section, it will be ignored.

[0032] It is understandable that the identification feature may also be the size of the identification ball, and the identification balls on different screens have different sizes (diameters). In this embodiment, the detector uses a camera, and the controller performs detection through an image recognition algorithm.

[0033] From the above, it can be seen that the identification ball of the monitoring device of the utility model is placed on the screen of the vibrating screen, and the ball retaining net and the detector are arranged on the discharging part. The detector can detect in real time whether there is an identification ball on the corresponding ball retaining net to determine whether the screen is damaged, thereby realizing the monitoring of screen damage, so that the damage of the screen can be discovered in time, thereby ensuring the screening effect, as well as the quality and purity of the final product.

[0034] Obviously, those skilled in the art should realize that the above embodiments are only used to illustrate the present invention, and are not used to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
