The upper and lower parts inside the bearing frame (the side close to the tensioning roller) are horizontally provided with an upper slide rail and a lower slide rail. The bearing with a slider seat is installed between the upper slide rail and the lower slide rail and can perform directional horizontal displacement along the upper slide rail and the lower slide rail. One end of the screw rod abuts against (fits tightly with) the bearing position of the bearing with a slider seat (one end of the screw rod is embedded in the through hole on one side of the bearing with a slider seat, and the embedded end of the screw rod is larger than the aperture of the through hole), and the other end passes through the side frame of the bearing frame with a threaded hole to form a threaded fastening structure. The screw rod is also equipped with a nut for limiting. The bearing frame is welded and fixed to the outside of the box body through the tensioning device cover. The tensioning device cover plays a role in protecting the internal components, and there is enough installation space between the tensioning device cover and the screw rod and the bearing with a slider seat;

[0009] The two sets of adjusting device assemblies are respectively arranged at the upper and lower parts of the box body; the adjusting device assembly includes a slide rail frame, a first slide rail, a second slide rail, an electric cylinder slider assembly, an adjusting device cover, a slider screw rod, a bearing with a slider seat, and an electric cylinder.

The upper and lower parts of the electric cylinder slider assembly are respectively provided with grooves matching the first slide rail and the second slide rail. The electric cylinder slider assembly is provided with a groove matching the joint of the slider screw rod. One end of the slider screw rod is assembled with the groove of the electric cylinder slider assembly, and the screw rod at the other end passes through the side opening of the slide rail frame. Nuts for limiting are arranged on the slider screw rods on both sides of the slide rail frame. A pin hole is opened in the middle of the electric cylinder slider assembly, and a pin hole is also opened at one end of the electric cylinder close to the electric cylinder slider assembly. The electric cylinder slider assembly and the electric cylinder are connected by a bolt passing through the pin holes. The bearing with a slider seat is installed between the first slide rail and the second slide rail. The bearing with a slider seat is connected to the electric cylinder through a tensioning roller, so that it can perform directional horizontal displacement. The through hole at one end of the electric cylinder far from the electric cylinder slider assembly is fixed on the tensioning roller at the slider seat bearing. The slider screw rod can drive the electric cylinder slider assembly. The main function of the electric cylinder slider assembly is to serve as a connecting structure to connect the slider screw rod and the electric cylinder and move directionally along the slide rail direction. During the equipment installation process, by adjusting the length of the slider screw rod, the positions of the electric cylinder slider assembly, the electric cylinder, and the tensioning roller can be initially determined in sequence. The slide rail frame is welded and fixed to the outside of the box body through the adjusting device cover. Specifically, the adjusting device cover is provided with openings and is fixed to the slide rail frame through bolts. The adjusting device cover plays a role in protecting the internal components of the adjusting device assembly;

[0010] The two groups of sensor components are respectively installed and fixed in the boxes on the left and right sides of the belt. The sensor component includes a connecting angle steel, a fixing angle steel and a sensor. The sensor is arranged on the side of the belt through the connecting angle steel and the fixing angle steel. The limit switch on the sensor can contact the side of the belt. When the equipment is working, the displacement of the belt is transmitted to the control unit through the action signal of the limit switch on the sensor. When the belt deviation reaches a certain displacement, the sensor will be triggered to transmit its signal to the control unit. The sensor component is assembled after the belt is initially positioned. The sensor component is used to feedback signals.

[0011] The sensor component transmits signals to the control unit according to the contact action between the belt and the limit switch on the sensor. The control unit performs corresponding actions through the electric cylinder in the adjustment device component. The bearing with a slider seat slides along the direction of the slide rail frame following the electric cylinder, so as to drive the tensioning roller to adjust the tightness of the belt.

[0012] The tensioning device component, the adjustment device component and the sensor component are respectively connected to the control unit for communication.

[0013] Further, the two tensioning rollers are respectively the first tensioning roller and the second tensioning roller. The two ends of the first tensioning roller are respectively in interference fit with the bearings of the tensioning device component and the bearing with a slider seat of the adjustment device component located at the upper part of the box. The shaft shoulders of the tensioning roller respectively abut against both sides of the bearings of the tensioning device component and the adjustment device component, so as to position the first tensioning roller.

[0014] The two ends of the second tensioning roller are respectively in interference fit with the bearings of the tensioning device component and the bearing with a slider seat of the adjustment device component located at the lower part of the box. The shaft shoulders of the tensioning roller respectively abut against both sides of the bearings of the tensioning device component and the adjustment device component, so as to position the second tensioning roller.

[0015] Further, there are three idler rollers. The two ends of the first idler roller and the second idler roller are respectively in interference fit with the bearings in the idler roller bearing seat component A and the idler roller bearing seat component B. The shaft shoulders of the first idler roller and the second idler roller respectively abut against both sides of the bearings of the idler roller bearing seat component A and the idler roller bearing seat component B, so as to position the idler rollers. The third idler roller is located at the bottom of the belt and is positioned according to the box structure. Its assembly method is the same as that of the first idler roller and the second idler roller, that is, its two ends are in hole-shaft assembly with the bearings in the idler roller bearing seat A and the idler roller bearing seat component B, and the shaft shoulders of the third idler roller respectively abut against the two end bearing seats for axial positioning. The function of the third idler roller is "to support the weight of the belt and the material, reduce the running resistance of the belt and prevent the belt from sagging".

[0016] Further, the belt is made of PPS, which is a flexible material of high-performance thermoplastic resin. The belt is similar to a rainproof rolling cloth with a width of 4 meters. When it is installed, the tensioning roller and the supporting roller in the equipment need to be initially installed and positioned on the box body. First, the belt is laid into the equipment from one end along the fixed route of the tensioning roller and the supporting roller by manual or equipment dragging. The belt needs to be wound around to the initial point to form a circle. Then, the positioning of the tensioning roller and the supporting roller is adjusted in detail. Finally, the end of the belt is tightened with the first section to make it close to the roller and then sewn.

[0017] Further, the end of the screw rod away from the bearing of the slider seat is square and can be screwed with a wrench tool.

[0018] Further, the end of the slider screw rod away from the bearing of the slider seat is square, which is convenient for screwing with a wrench tool.

[0019] Further, the box body is of a square structure, with side wall steel plates and maintenance manholes installed on both sides. The front side is used for assembly and installation with other equipment. The rear side is installed with double doors. The top is used for installing gas collection equipment, and the bottom is installed and fixed on a stable foundation plane.

[0020] Further, adjustable bolt holes (waist-shaped holes) are provided on the fixed angle steel; bolt holes are opened on the connecting angle steel, and the connecting angle steel is connected and fixed to the adjustable bolt holes of the fixed angle steel through bolts and nuts.

[0021] Further, the fixed angle steel is fixed (such as welded) inside the box body, and the connecting angle steel is connected to the fixed angle steel; the sensor is connected to the adjustable bolt holes of the connecting angle steel through bolts and nuts, and the sensor can realize horizontal and height adjustment through the adjustable bolt holes of the connecting angle steel and the fixed angle steel.

[0022] The working principle of the deviation correction device of the sludge thermal coupling system of the present utility model:

[0023] First, the belt 7 is initially installed on the tensioning roller 2 and the idler roller 5. By adjusting the screw 9 in the tensioning device assembly 3, the belt 7 on this side is in a relatively tight working state. Secondly, through the combined adjustment of components such as the electric cylinder slider assembly 15, the slider screw 17, and the bearing 11 with a slider seat in the adjustment device assembly 4. Specifically, by adjusting the position of the nut matching the slider screw 17 in the adjustment device assembly 4, the purpose of adjusting the screw length of the slider screw 17 is achieved. Therefore, the electric cylinder slider assembly 15, the electric cylinder 18, the tensioning roller 2, and the bearing 11 with a slider seat can be driven to displace along the slide rail direction in sequence (the relevant components are all connected in a reliable connection manner). Since the belt 7 on the side corresponding to the tensioning device assembly 3 has been tightened, the displacement of the corresponding components in the adjustment device assembly 4 in the distal direction will tighten the belt on this side, so as to meet the purpose of the belt in the equipment reaching the required tightness state. Make the belt 7 on this side also in a relatively tight working state. Finally, the sensor assembly 6 is installed according to the current position of the belt 7, so that the limit switch of the sensor 21 of the sensor assembly 6 can contact the side of the belt 7;

[0024] Before the equipment is put into trial operation, the interlock signal between the electric cylinder 18 and the sensor 21 needs to be set, and the displacement parameters of the electric cylinder 18 are set. When the equipment is in trial operation, according to the working conditions of the belt 7, the position of the sensor assembly 6 and the displacement parameter of the electric cylinder 18 are adjusted to meet the control of the displacement of the tensioning roller 2 on one side of the belt 7, further control the tightness of this side of the belt 7, and further correct the deviation of the belt 7; Specifically, if the belt 7 runs off to the side of the adjustment device assembly 4, the sensor 21 on this side transmits the touch signal of the belt 7 to the electric cylinder 18. After receiving the signal, the electric cylinder 18 makes a displacement action for a certain distance. At this time, the tightness of the belt 7 on this side increases, so a force for displacement to the other side of the belt 7 is generated. During the continuous operation of the equipment, the belt 7 deviates to the opposite side under the action of this force until the sensor 21 no longer receives the touch signal of the belt 7. At this time, after receiving the signal of the sensor 21, the electric cylinder 18 maintains its position without moving, and this is regarded as the position of the belt 7 returning to the normal working condition. Similarly, if the belt 7 deviates to the side of the tensioning device assembly 3, the electric cylinder 18 will make a reverse displacement action according to the signal, so as to make the position of the belt 7 return to the normal working condition position.

[0025] The deviation correction device of the sludge thermal coupling system of the present utility model, when the belt in the system starts to be installed, after the belt is initially positioned by installing the tensioning roller and the idler roller, the tensioning device assembly and the adjustment device assembly are adjusted in sequence, so as to finely adjust the tightness state of the belt. When the equipment runs to drive the belt to run for a trial, if the belt runs off or shifts, it will contact the sensor assemblies on both sides in the box body. The sensor assemblies will feedback the signals to the adjustment device assembly. The electric cylinder of the adjustment device assembly will execute corresponding actions according to the signals, and adjust a certain displacement in the conveying direction of the belt through the tensioning roller, and then adjust the tightness degree of the belt, so as to generate a force in the opposite direction of the running deviation of the belt, so as to achieve the purpose of correcting the belt deviation. Specifically, the deviation correction device of the sludge thermal coupling system of the present utility model has the following advantages compared with the prior art:

[0026] 1) The deviation correction device of the sludge thermal coupling system of the present utility model can adjust the belt to the correct position through the interlocking signals of the sensor assembly and the adjustment device assembly, prevent serious wear on the edge of the belt, and even prevent phenomena such as belt tearing or belt jamming;

[0027] 2) The deviation correction device of the sludge thermal coupling system of the present utility model is conducive to the non-stop operation of the sludge thermal coupling system, improves the working efficiency of the equipment, and reduces the maintenance time of the equipment.

[0028] 3) The structural components of the deviation correction device of the sludge thermal coupling system of the present utility model make full use of the side wall of the box body structure, do not occupy additional land area, and the equipment has a high degree of integration and automation.

[0029] In summary, the deviation correction device of the sludge thermal coupling system of the present utility model avoids traditional shutdown deviation correction, and improves the working efficiency and automation degree of the equipment. Brief Description of the Drawings

The opening on the frame structure is used to install the hexagon socket head cap screw and fix the frame to the side wall plate of the box body 1; The tensioning device shield 8 is installed outside the bearing frame 10. This shield can protect the internal components of the tensioning device. At the same time, because it adopts the structure of a handle-end cover, it is convenient for equipment installation, adjustment and maintenance; The screw 9 is installed at the bearing frame 10 and the bearing with a slider seat 11 and is equipped with nuts, used to adjust the position of the bearing with a slider seat 11 and act on the belt 7 of the tensioning roller 2 to tighten the belt 7.

[0043] The adjustment device assembly 4 includes a slide rail frame 12, a first slide rail 13, a second slide rail 14, an electric cylinder slider assembly 15, an adjustment device shield 16, a slider screw 17, an electric cylinder 18 and a bearing with a slider seat 11, specifically as Figure 4 and Figure 5As shown. The adjustment device assembly 4 is divided into two groups and is respectively installed at the corresponding positions on the right side wall plate of the box body 1 on the opposite side of the tensioning device assembly 3. When the electric cylinder acts according to the interlock signal, the positioning of the tensioning roller 2 is also adjusted accordingly. The slide rail frame 12 is installed outside the box body and is installed in cooperation with the first slide rail 13 and the second slide rail 14, and is used to provide the track for the electric cylinder slider assembly 15 and the bearing 11 with a slider seat; the electric cylinder slider assembly 15 is installed on the slide rail and is used to adjust the positioning of the electric cylinder 18; the adjustment device shield 16 is installed outside the slide rail frame 12, which can protect the internal components of the adjustment device. At the same time, due to its flange structure, it is convenient for equipment installation adjustment and maintenance; the slider screw 17 is installed at the slide rail frame 12 and the electric cylinder slider assembly 15, and is installed in sequence in cooperation with the electric cylinder 18 and the bearing 11 with a slider seat. The main function of the adjustment device assembly 4 is to act on the belt 7 of the tensioning roller 2 through the action of the electric cylinder 18 to adjust the tightness of the belt 7.

[0044] The sensor assembly 6 includes a connecting angle steel 19, a fixing angle steel 20 and a sensor 21, specifically as Figure 6 shown. The sensor assembly 6 is divided into two groups and is respectively installed on both sides of the belt 7. After the installation position of the belt 7 is basically determined, the sensor assembly 6 is assembled with the internal structure of the box body 1. The fixing angle steel 20 is used for welding to the box body and is used in cooperation with the connecting angle steel 19; the connecting angle steel is used to connect the fixing angle steel 20 and the sensor 21, and the position of the sensor 21 can be appropriately adjusted according to the position of the belt 7.

[0045] The working principle of the deviation correction device of the sludge thermal coupling system in this embodiment is as follows. First, the belt 7 is initially installed on the tensioning roller 2 and the idler roller 5. By adjusting the screw 9 in the tensioning device assembly 3, the belt 7 on this side is in a relatively tight working state. Secondly, through the combined adjustment of components such as the electric cylinder slider assembly 15, the slider screw 17 and the bearing 11 with a slider seat in the adjustment device assembly 4, the belt 7 on this side is also in a relatively tight working state. Finally, the sensor assembly 6 is assembled according to the current position of the belt 7;

[0046] Before the equipment is put into trial operation, it is necessary to interlock the electric cylinder 18 with the sensor 21 and set the displacement parameters of the electric cylinder 18;

[0047] During the trial operation of the equipment, according to the working condition of the belt 7, the position of the sensor assembly 6 and the displacement parameter of the electric cylinder 18 are adjusted to control the displacement of the tensioning roller 2 on one side of the belt 7, further control the tightness of this side of the belt 7, and further correct the deviation of the belt 7; specifically, if the belt 7 runs off to the side of the adjustment device assembly 4, the sensor 21 on this side transmits the touch signal of the belt 7 to the electric cylinder 18. After receiving the signal, the electric cylinder 18 makes a displacement action for a certain distance. At this time, the tightness of this side of the belt 7 increases, so a force for displacement to the other side of the belt 7 is generated. During the continuous operation of the equipment, the belt 7 deviates to the opposite side under the action of this force until the sensor 21 no longer receives the touch signal of the belt 7. At this time, after receiving the signal from the sensor 21, the electric cylinder 18 keeps its position unchanged, and at this time, it is regarded that the position of the belt 7 returns to the normal working condition. Similarly, if the belt 7 deviates to the side of the tensioning device assembly 3, the electric cylinder 18 will make a reverse displacement action according to the signal to make the position of the belt 7 return to the normal working condition position.
