[0004] The wire dewatering structure in the above patent still has the following shortcomings:

[0005] During long-term operation, the current mesh structure is prone to changes in the tightness of the screen due to the tension of the device or the aging and loosening of parts. As a result, the middle area of ​​the screen may fall downward, which may easily cause pulp to accumulate during the dehydration process, thereby affecting the effect and efficiency of pulp dehydration and being detrimental to the normal operation of the equipment. The above patent lacks a monitoring device for the status of the screen and cannot monitor and remind the status of the screen in a timely manner, which has certain limitations.

[0022] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.

[0023] Embodiment 1:

[0024] As attached Figure 1 To Attachment Figure 6 As shown:

[0025] The utility model provides a net dewatering structure, comprising: a base 1; the base 1 adopts a rectangular frame structure, and two groups of bases 1 are provided, and the two groups of bases 1 are symmetrically provided; a group of slide rails 2 are fixedly provided in the middle of the tops of the two groups of bases 1; there are two groups of slide rails 2; a first slider 202 of a rectangular block structure is slidably provided on the inner side of the slide rail 2, and a through-type screw hole structure is provided on the top of the first slider 202; a group of mounting plates 203 of a rectangular plate structure are fixedly provided on the upper and lower sides of the first slider 202, and a through-type screw hole structure is provided on the tops of the two groups of mounting plates 203; a slide bar 206 of a rectangular rod structure is fixedly connected between the two groups of mounting plates 203, and a spring is sleeved on the outer side of the slide bar 206; a second slider 207 of a rectangular frame structure is slidably provided on the outer side of the slide bar 206; a contact rod 208 of a cylindrical structure is rotatably provided on one side of the second slider 207.

[0026] Among them, a lead screw 201 is rotatably arranged on the inner side of the slide rail 2, and the lead screw 201 is transmission-connected to the first slider 202; a screw rod 204 is rotatably arranged in the screw hole of the mounting plate 203 through threaded cooperation; a proximity switch 205 is fixedly arranged at one end of the screw rod 204, and the proximity switch 205 is electrically connected to the alarm 108; a group of induction switches 209 are fixedly arranged on both the upper and lower sides of the second slider 207.

[0027] The specific usage and function of this embodiment are as follows:

[0028] The first slider 202 can be driven to slide up and down along the inner side of the slide rail 2 by rotating the lead screw 201, thereby synchronously driving the slide bar 206 and the second slider 207 to move, so that the contact rod 208 on one side of the second slider 207 moves to a position in contact with the screen 102, and under the pressure of the screen 102, pressure is applied to the contact rod 208 and the second slider 207, so that the second slider 207 moves to the middle area of ​​the slide bar 206. During the operation of the screen 102, if the screen 102 becomes loose, the middle area of ​​the screen 102 will tend to fall, thereby pressing the contact rod 208 and the second slider 207 to move downward along the slide bar 206. After exceeding the warning interval, a group of induction switches 209 at the bottom of the second slider 207 are close to a group of proximity switches 205 below, and the proximity switches 205 synchronously turn on the alarm 108, thereby giving a fault alarm to the surrounding staff, so that the staff can monitor the status of the screen 102 in time, and can find and eliminate abnormalities in time when they occur, so as to ensure the smooth progress of the dehydration process.

[0029] Embodiment 2:

[0030] Based on Example 1, as shown in the attached Figure 1 To Attachment Figure 6 As shown:

[0031] Among them, a dehydration device 101 is fixedly arranged on the top rear side of the two groups of bases 1; a screen 102 is rotatably arranged between the two groups of bases 1; a first motor 103 is fixedly arranged on one side of the base 1, and the first motor 103 is transmission-connected to the screen 102; a group of cylindrical fixing rods 104 are fixedly arranged on the front sides of the two groups of bases 1, and a spring is sleeved on the outer side of the fixing rods 104; a connecting block 105 with a U-shaped block structure is slidably arranged on the outer side of the two groups of fixing rods 104; a cleaning roller 106 with a cylindrical structure is rotatably arranged between the two groups of connecting blocks 105, and a cleaning brush structure is arranged on the outer side of the cleaning roller 106; a second motor 107 is fixedly arranged on one side of the connecting block 105, and the second motor 107 is transmission-connected to the cleaning roller 106; an alarm 108 is fixedly arranged in the middle of the top of the dehydration device 101.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In the utility model, during operation, the pulp is laid on the front top of the screen 102, and the screen 102 is driven by the first motor 103 to continuously rotate on the two sets of bases 1, so that the pulp can move backward along the rotation direction of the screen 102, so that it can move to the bottom of the dewatering device 101 and be dehydrated by the dewatering device 101. After dehydration, during the movement of the screen 102, the pulp falls from the bottom of the screen 102 to the next process, and the screen 102 continues to rotate. During the process, the second motor 107 is started synchronously, and the cleaning roller 106 is driven to rotate by the second motor 107. The two sets of connecting blocks 105 slide backward along the fixed rod 104 under the action of the spring on the outer side of the fixed rod 104, thereby synchronously driving the brush structure on the outer side of the cleaning roller 106 to contact the screen 102, and continuously clean the residual pulp on the screen 102, thereby maintaining the permeability of the screen holes on the screen 102, avoiding the screen holes being blocked by the residual pulp, and affecting the water permeability of the screen 102.
