Description

Technical Field

[0001] This utility model relates to the field of urea production technology, specifically to a vibrating screen body suspension device. Background Technology

[0002] Currently, in the production process of urea in nitrogen fertilizer plants, there is a screening operation. Specifically, this process generally uses a screen to screen urea particles. Before use, one end of the screen needs to be suspended on a fixed frame by two sets of suspension devices, and then the other end of the screen is connected to an eccentric wheel. When the motor drives the eccentric wheel to rotate, the eccentric wheel can drive the screen to swing back and forth, thereby achieving the screening of urea particles.

[0003] The aforementioned suspension device typically consists of two lifting rings, two shackles, and a connecting rod. During installation, the two lifting rings are first fixed to the fixed frame and the screen body respectively. Then, the two shackles are fastened to the two lifting rings. Finally, the connecting rod connects the two shackles, completing the installation of the suspension device. However, during prolonged reciprocating shaking of the screen body, wear will occur between the shackles and the lifting rings, causing the position of the shackles on the lifting rings to change. This results in a change in the initial position of the screen body relative to the fixed frame. This change in the screen body's installation position will deform the subsequent screening action, leading to a decrease in the screening effect for urea particles. Simply replacing the suspension device periodically not only increases production costs but also requires a long downtime for disassembly and reassembly, reducing screening efficiency.

[0004] To address these issues, we propose a vibrating screen body suspension device. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art by proposing a vibrating screen body suspension device. After long-term wear and tear causes the distance between the first and second adapter parts to increase, the distance between the first and second adapter parts can be adjusted by the retraction of the telescopic part, so that the distance between the first and second adapter parts is consistent with the initial distance. This facilitates the screen body to maintain good screening action and improves the screening effect.

[0006] To solve the above problems, this utility model provides the following technical solution:

[0007] A vibrating screen body suspension device includes a first adapter on a fixed frame and a second adapter on the screen body, wherein the first adapter and the second adapter are connected by a telescopic member. The telescopic member includes a frame, and the two ends of the frame along its length are respectively provided with a connecting hook and a connecting ring. The connecting hook is hung on the first adapter, and the connecting ring is rotatably mounted on the second adapter.

[0008] As a further embodiment of this utility model: the connecting hook and / or connecting ring has a threaded section, and the connecting hook and / or connecting ring is threadedly installed on the frame by the threaded section, the threaded section penetrates into the interior of the frame, and the frame is provided with a locking device for locking the threaded section.

[0009] As a further embodiment of this utility model: when both the connecting hook and the connecting ring have threaded sections, the connecting hook, the connecting ring, and the frame together constitute a bidirectional threaded sleeve mechanism.

[0010] As a further embodiment of this utility model: the locking component includes a push rod threaded onto the frame, one end of which penetrates into the interior of the frame and can abut against the threaded section to exert a lateral force on the threaded section.

[0011] As a further embodiment of this utility model: the lock also includes a swing block hinged inside the frame, and the swing block has teeth on the side facing the threaded section. The push rod has a pin rotatably mounted on one end inside the frame, and the pin is movably connected to the swing block so that when the push rod drives the swing block to approach the threaded section, the teeth can engage with the threads on the threaded section.

[0012] As a further embodiment of this utility model: a sliding groove is provided on the swing block, and a slider is movably disposed on the sliding groove, and the pin on the push rod is hinged to the slider.

[0013] As a further embodiment of this utility model: the first adapter includes a U-shaped seat, and pins for attaching connecting hooks are provided on the two parallel portions of the U-shaped seat.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By using the telescopic component, the distance between the first and second adapters can be adjusted. When the connecting hook and connecting ring wear against the first and second adapters respectively, causing the distance between the first and second adapters to increase, the distance between the connecting hook and connecting ring can be reduced to maintain a constant distance between the first and second adapters. This, in turn, ensures a constant distance between the screen body and the fixed frame. Maintaining this distance ensures that the screening action of the screen body remains good, resulting in a good screening effect for urea particles.

[0016] 2. By installing the connecting hook and / or connecting ring onto the frame via the threaded section, the position of the connecting hook and / or connecting ring on the frame is easily adjustable, and wear compensation can be achieved simply by driving the connecting hook and / or connecting ring to rotate.

[0017] 3. By setting the locking mechanism, the locking mechanism will lock the threaded section when the suspension device is in normal use, so as to keep the position of the threaded section stable and ensure that the position of the suspension device will not move under normal use. When it is necessary to adjust the suspension device, the locking mechanism will be released from the threaded section, and the operator can drive the threaded section to perform the corresponding rotation adjustment action.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] like Figures 1-3As shown, a vibrating screen body suspension device includes a first adapter 1, a second adapter 2, and a telescopic member 3 for connecting the first adapter 1 and the second adapter 2. The telescopic member 3 includes a frame 301, with a connecting hook 302 and a connecting ring 303 respectively provided at both ends along its length. The connecting hook 302 is hung on the first adapter 1, and the connecting ring 303 is rotatably mounted on the second adapter 2 to realize the connection between the first adapter 1 and the second adapter 2. In use, the first adapter 1 is installed on a fixed frame, and the second adapter 2 is installed on the screen body. The first adapter 1, the second adapter 2, and the telescopic member 3 together form a suspension to realize the connection of the screen body.

[0025] like Figure 2 As shown, the first adapter 1 typically includes a U-shaped base 101. The two parallel portions of the U-shaped base 101 are provided with pins 102 for the connecting hook 302 to be hung on. The connecting hook 302 is hung on the pins 102. To improve the service life of the U-shaped base 101, the two parallel portions of the U-shaped base 101 that can contact the connecting hook 302 can be thickened. Of course, the design of the second adapter 2 can also be consistent with the structural design of the first adapter 1; however, to avoid unnecessary detail, this will not be elaborated upon here.

[0026] Generally, during use, the initial distance between the first adapter 1 and the second adapter 2 is the optimal distance. At this time, the suspension device maintains the height of the screen body, allowing the screen body to perform good screening under the action of the eccentric wheel. However, due to prolonged screening operation, wear will occur between the telescopic component 3 and the first adapter 1 and the second adapter 2. That is, wear will occur between the connecting hook 302 and the connecting ring 303 and the first adapter 1 and the second adapter 2, respectively, thus increasing the distance between the first adapter 1 and the second adapter 2. To solve the problem of increased distance caused by wear, this utility model makes the position of the connecting hook 302 and / or the connecting ring 303 on the frame 301 adjustable. Thus, when the distance between the first adapter 1 and the second adapter 2 increases due to wear, the distance between the connecting hook 302 and the connecting ring 303 can be adjusted to reduce the distance, thereby compensating for the distance caused by wear and ensuring that the first adapter 1 and the second adapter 2 always maintain the same distance as the initial state.

[0027] There are three possible installation designs where the positions of the connecting hook 302 and the connecting ring 303 are adjustable on the frame 301:

[0028] (1) Both the connecting hook 302 and the connecting ring 303 have threaded sections 304. Both the connecting hook 302 and the connecting ring 303 are threaded onto the frame 301 via the threaded sections 304. The threaded sections 304 penetrate into the interior of the frame 301. This design can be achieved by… Figures 1-3 To illustrate: When wear occurs between the connecting hook 302 and the connecting ring 303 and the first adapter 1 and the second adapter 2 respectively, the connecting hook 302 and the connecting ring 303 can be removed from the first adapter 1 and the second adapter 2 respectively. Then, the connecting hook 302 and the connecting ring 303 can be rotated by the threaded section 304, thereby reducing the length between the connecting hook 302 and the connecting ring 303, thus solving the problem of increased distance between the connecting hook 302 and the connecting ring 303 due to wear.

[0029] (2) The connecting hook 302 has a threaded section 304. The connecting hook 302 is threaded onto the frame 301 by the threaded section 304, and the threaded section 304 penetrates into the interior of the frame 301. When the connecting hook 302 and the connecting ring 303 wear with the first adapter 1 and the second adapter 2 respectively, the connecting hook 302 is rotated by the threaded section 304, so that the length between the connecting hook 302 and the connecting ring 303 is reduced, thereby solving the problem of the increased distance between the connecting hook 302 and the connecting ring 303 due to wear.

[0030] (3) The connecting ring 303 has a threaded section 304. The connecting ring 303 is threaded onto the frame 301 by the threaded section 304, and the threaded section 304 penetrates into the interior of the frame 301. When the connecting hook 302 and the connecting ring 303 wear with the first adapter 1 and the second adapter 2 respectively, the connecting ring 303 is rotated by the threaded section 304, so that the length between the connecting hook 302 and the connecting ring 303 is reduced, thereby solving the problem of the increased distance between the connecting hook 302 and the connecting ring 303 due to wear.

[0031] Of course, when both the connecting hook 302 and the connecting ring 303 have threaded sections 304, the connecting hook 302, the connecting ring 303 and the frame 301 together constitute a bidirectional threaded sleeve mechanism. At this time, it is only necessary to rotate the frame 301 to make the connecting hook 302 and the connecting ring 303 move closer to each other.

[0032] like Figure 3 As shown, in order to ensure that the threaded section 304 can maintain a stable working state after rotational adjustment, this utility model also includes a locking component for locking the threaded section 304. Specifically, the locking component includes a push rod 6 threaded onto the frame 301. One end of the push rod 6 penetrates into the interior of the frame 301 and can abut against the threaded section 304. This horizontal abutment is used to apply a horizontal lateral force to the threaded section 304, ensuring the stability of the position of the threaded section 304.

[0033] Furthermore, the locking mechanism also includes a swing block 4 hinged inside the frame 301, with teeth 5 on the side of the swing block 4 facing the threaded section 304. A pin 7 is rotatably mounted on one end of the push rod 6 inside the frame 301, and the pin 7 is movably connected to the swing block 4. When the push rod 6 drives the swing block 4 closer to the threaded section 304, the teeth 5 can engage with the threads on the threaded section 304, locking the threaded section 304 and preventing it from moving vertically, thus locking the distance between the connecting hook 302 and the connecting ring 303. Subsequently, rotating the push rod 6 outwards will move the swing block 4 away from the threaded section 304, releasing the lock on the threaded section 304, allowing the operator to rotate the threaded section 304 accordingly. Of course, the locking mechanism is not limited to the above design; bolts can also be simply installed on the frame 301 to press the threaded section 304 into place for locking.

[0034] To accommodate the locking mechanism composed of the swing block 4 and the push rod 6, a groove 8 is provided on the swing block 4, and a slider 9 is movably mounted on the groove 8. The pin 7 on the push rod 6 is hinged to the slider 9. During the left and right movement of the push rod 6, the pin 7 can drive the slider 9 to move on the groove 8. At the same time, the movement of the slider 9 can also drive the swing block 4 to rotate accordingly, thus realizing the corresponding work of the swing block 4.

[0035] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
