Description
Technical Field
[0001] This utility model belongs to the field of screen detection and relates to a screen hole detection device. Background Technology
[0002] High-frequency screens are common screening equipment, but the high-frequency screen mesh, one of their core components, is a vulnerable part. Depending on the properties of the ore, the wear cycle and degree of wear vary. When abnormalities occur in the fineness of the production target, technicians or operators need to inspect the wear of the high-frequency screen mesh when it is stopped or there is no slurry flow. This requires reducing or even stopping the feed rate to meet the inspection requirements, disrupting normal production. Furthermore, due to the low level of automation, a large number of high-frequency screens need to be inspected each time, often requiring multiple people to work together. Operations such as reducing the feed rate, sealing the branch outlet, and flushing the high-frequency screens are time-consuming and extremely inconvenient. Summary of the Invention
[0003] This application provides a screen hole detection device, which can inspect abnormal situations such as large-area damage to the screen or slight screen detachment.
[0004] To achieve the above technical objectives, the technical solution adopted in this application is a screen hole detection device, comprising: A horizontal plate, with a universal ball joint socket fixed in the middle; the horizontal plate has multiple through holes on both sides of the universal ball joint socket; A metal rod passes through the through hole, with an upper intercepting rod above the horizontal plate at the top and a lower intercepting rod below the horizontal plate at the bottom; a contact is provided at the bottom of the metal rod. A long rod with a universal ball joint at its end, the universal ball joint being mounted on a universal ball joint socket and capable of rotating around the universal ball joint socket.
[0005] As an improved technical solution of this application, the contact is a smooth component.
[0006] As an improved technical solution of this application, the diameter of the through hole is larger than the diameter of the metal rod.
[0007] As an improved technical solution of this application, the horizontal plate is a cuboid structure.
[0008] As an improved technical solution of this application, the horizontal plate is made of stainless steel.
[0009] As an improved technical solution of this application, the long rod is made of stainless steel.
[0010] As an improved technical solution of this application, the metal rod is made of stainless steel.
[0011] Beneficial effects This application utilizes a long rod in conjunction with a universal ball joint to achieve free sliding of the entire device; by utilizing the cooperation between the metal rod and the through hole, the metal rod's own weight enables it to slide along the through hole and fall into the hole at the hole, thereby completing the detection of the screen hole.
[0012] The technical solution of this application enables the preliminary detection of damaged or detached screens without stopping or reducing the feed rate and with one person operating the equipment, so that abnormal screens can be replaced in a timely manner and production indicators can be restored.

[0015] The technical solution of this application is designed to inspect abnormal situations such as large-area damage or slight detachment of screens. Through a screen hole detection device, the damaged or detached screens can be detected in advance without stopping or reducing the feed rate and with one person operating the device, so that the abnormal screens can be replaced in time and production indicators can be restored.
[0016] like Figure 1-4 As shown, a screen hole detection device includes... A horizontal plate 8 has a universal ball joint socket 6 fixed in its middle position; the horizontal plate 8 has multiple through holes 5 on both sides of the universal ball joint socket 6. Metal rod 3 passes through the through hole 5, and the upper part of the metal rod 3 is provided with an upper intercepting rod 4 above the horizontal plate 8, and the lower part is provided with a lower intercepting rod 2 below the horizontal plate 8; the bottom of the metal rod 3 is provided with a contact 1. The long rod 7 has a universal ball joint at its end, which is mounted on the universal ball joint socket 6 and can rotate around the universal ball joint socket 6.
[0017] To prevent damage to the screen when the contact 1 slides, the contact 1 is a smooth component, specifically a hemispherical structure or a stainless steel ball.
[0018] To facilitate the smooth entry of the metal rod 3 into the hole, the diameter of the through hole 5 is larger than the diameter of the metal rod 3.
[0019] As an improved technical solution of this application, the horizontal plate 8 is a cuboid structure.
[0020] As an improved technical solution of this application, the horizontal plate 8 is made of stainless steel.
[0021] As an improved technical solution in this application, the long rod 7 is made of stainless steel.
[0022] As an improved technical solution of this application, the metal rod 3 is made of stainless steel.
[0023] Example 1 A screen hole detection device includes a smooth contact 1 that directly contacts the high-frequency screen and can slide easily on the screen surface without damaging it. The contact 1 is located at the bottom of a metal rod 3. An upper intercepting rod 4 is welded to the top of the metal rod 3, allowing it to move up and down through a through hole 5. However, a lower intercepting rod 2 is located above the contact 1. Both the lower and upper intercepting rods serve to prevent the metal rod 3 from detaching from the through hole 5 during movement. The through hole 5 is located on a transverse plate 8. A universal ball joint socket 6 is welded to the middle of the transverse plate 8, and the other end of the universal ball joint socket 6 is welded to a long rod 7.
[0024] To facilitate the explanation of the working principle of a screen hole detection device, the entire assembly consisting of contact 1, lower intercepting rod 2, metal rod 3, and upper intercepting rod 4 is referred to as the "metal rod".
[0025] The working principle of a screen hole detection device is as follows: When a high-frequency screen experiences large-area damage or slight screen detachment, the device is first placed on the high-frequency screen by holding the long rod 7. Each metal rod 3 has a contact 1 corresponding to an area on the high-frequency screen separated by nine raised ridges. Since the bottom of the long rod 7 is connected to the ball joint 6, it can rotate left, right, up, and down, allowing the entire device to move back and forth. During the movement, if a large-area damage or slight screen detachment occurs, the metal rod 3 will fall through the through hole 5 into the damaged screen hole under gravity. At this point, the relative position of the metal rod 3 at this location will be significantly different from the other metal rods 3, indicating that the screen at that location is abnormal and needs replacement. Because the top of the metal rod 3 has an upper intercepting rod 4, it is blocked when it reaches the through hole 5, preventing the entire metal rod 3 from falling off the device. Similarly, when the device is placed on the screen, the metal rod 3 will not fall off the entire device due to the blocking effect of the lower intercepting rod 2. When the device detects a large breakage or detachment of a high-frequency screen, it can roughly detect which screen in which screen is abnormal without stopping the flow of slurry, saving time and effort and improving production efficiency.
[0026] The lower interceptor bar 2 is a stainless steel strip with a diameter of 5mm and a length of 14mm, totaling 10 bars. It is horizontally welded 20mm above the bottom of the metal bar 3.
[0027] Metal rod 3 is a 5mm diameter, 100mm long stainless steel hollow tube, totaling 10 rods.
[0028] The upper interceptor bar 4 is a stainless steel strip with a diameter of 5mm and a length of 14mm, and there are 10 of them. They are horizontally welded to the top of the metal bar 3.
[0029] The through holes 5 are 8mm in diameter and there are 10 of them. Two of the through holes 5 are located at both ends of the horizontal plate 8, and the rest are evenly distributed on the horizontal plate 8.
[0030] The ball joint socket 6 is a metal product, which is welded onto the long rod 7 and the horizontal plate 8 respectively.
[0031] Long rod 7 is a 15mm diameter, 1000mm long stainless steel hollow tube. There are 10 of them in total.
[0032] The horizontal plate 8 is a cuboid with a length of 920mm, a width of 14mm, and a thickness of 3mm, made of welded stainless steel thin plates.
[0033] Example 2 Unlike Embodiment 1, in this screen hole detection device, the contact 1 is a smooth stainless steel ball, totaling 10, with a diameter of 5mm. It is welded to the bottom end of the metal rod 3.
