Description

Technical Field

[0001] The invention relates to the technical field of vacuum belt dehydrators, and in particular to a deviation adjusting device for vacuum belt dehydrators. Background Art

[0002] Vacuum belt dehydrators are widely used in industrial production in the process of gypsum vulcanization dehydration and other processes. During its operation, belt deviation is an extremely critical problem that needs to be solved urgently. The traditional vacuum belt dehydrator belt deviation adjustment mainly relies on manual experience judgment and manual operation. The operator needs to observe the running status of the belt at all times. Once deviation is found, the operator should adjust the deviation adjustment mechanism based on experience, such as adjusting the tensioning device, adjusting the roller angle, etc.

[0003] In the prior art, belt deviation is generally adjusted by extrusion to prevent the belt from deviation. Patent publication number CN110559725B discloses a vacuum belt dehydrator belt deviation adjustment device and a method of use, which prevents the belt from curling and deviation by squeezing the belt by the deviation adjustment pressure roller and the deviation adjustment roller, so that the belt can maintain stable operation, and the side pushing effect of the deviation adjustment vertical rollers on both sides can prevent side climbing. However, this extrusion method sometimes has a counterproductive effect. First, the belt may flip over during the extrusion process. Secondly, the belt edge may be damaged during the extrusion process. In addition, the machine needs to be shut down when the deviation is too large. The steps are cumbersome and are not conducive to the vulcanization and dehydration production of gypsum. Summary of the invention

[0015] The present invention provides a deviation adjustment device for a vacuum belt dehydrator, which has the following beneficial effects: 1. When one side of the filter belt deviates outward, it will squeeze the wheel on one side, and drive the rotating shaft to rotate through the swing frame, thereby driving the rack one to move through gear four, and then driving the upper or lower gear three to rotate, and then driving the lower gear two to rotate through the rotating rod, and driving the T-shaped baffle to rotate toward the swing frame on that side through gear one and the rotating rod. At this time, the air outlet slot is opened away from the swing frame on that side, and the gas is discharged from the air outlet away from the swing frame on that side and enters the interior of the adjustment part. Through the cooperation of the toggle part, the filter belt is adjusted to return to normal state. Conversely, when the other side of the filter belt deviates outward, the gas is discharged from the exhaust port close to the swing frame on that side. Through the monitoring and control part in the deviation adjustment mechanism, real-time monitoring of the filter belt is realized, and this process is mechanical transmission control, which avoids the problem of sensitivity of traditional monitoring sensors that leads to the failure to issue adjustment signals in time, resulting in untimely adjustment.

[0016] 2. When the filter belt deflects more, the wheel on one side is squeezed to make the swing frame rotate at a larger angle, so that more gas enters the adjustment part, the toggle part and the drying part, accelerating the adjustment of the filter belt amplitude, thereby avoiding the situation where the filter belt adjustment cannot meet the filter belt amplitude due to the slow recovery speed, or the material is not completely dried at the upper end of the filter cloth.

[0017] 3. When the gas enters the gas bin 1 from the gas pipe 1 on the other side, the gas pressure inside the gas bin 1 increases. At this time, the gas pressure will force the piston plate to move down, and drive the gear 5 to rotate through the piston rod, the universal bearing seat 1 and the rack 2, and then drive the rack 3 to move toward the rack 2 inside the sliding bin through the gear 6, and then drive the universal bearing seat 2 to move toward the rack 2 through the sliding seat, and finally drive the driven roller away from the end of the filter belt offset to rotate toward the rack 2. At this time, due to the displacement of the end of the driven roller away from the filter belt offset, the tension of the filter belt changes, which will cause the filter belt to move from the outer circumference of the driven roller to the end of the driven roller away from the filter belt offset. The filter belt is moved to the right end, and then the filter belt is adjusted to reset. After the filter belt is reset, the torsion spring drives the shaft to reset, the air outlet groove is re-blocked by the T-shaped baffle, the air pressure inside the air bin one returns to normal, the rack two is reset, and the universal bearing seat two resets the driven roller through the tension and the spring two on the outer periphery of the limit shaft. Through the cooperation of the adjustment part and the monitoring and control part in the deviation adjustment mechanism, when the deviation of one side of the filter belt is detected, the displacement of the other side of the driven roller is adjusted in time, so that the filter belt is automatically reset due to the tension change. Compared with the traditional method of compressing the filter belt to adjust the deviation of the filter belt, it will not cause damage to the filter belt and the adjustment effect is better.

[0018] 4. When the universal bearing seat on the side away from the filter belt deviation drops, it drives the adjusting lower pressure roller to drop, pressing the other side of the filter belt to move downward, which not only makes the adjustment effect better, but also makes the filter belt more effective and safer to avoid excessive deviation due to large tension changes during the adjustment process.

[0019] 5. When gas enters the air bin one, part of the gas will enter the air bin two from the air pipe two, driving the impeller to rotate, and then driving the knocking roller two to rotate through the rotating rod and the gear eight, intermittently pushing the filter cloth outward to offset the lower end of one side of the driven roller, so that when the filter belt is adjusted, the filter cloth is adjusted to move away from the filter belt and offset from the driven roller, thereby adjusting the filter cloth while adjusting the filter belt, avoiding the situation where the filter cloth is torn and affects the filtering effect.

[0020] 6. Gear 8 drives gear 7 to rotate, and then the filter belt is offset to one side of the driven roller by knocking roller 1, so that the auxiliary adjustment part can adjust the filter belt, improve the efficiency of adjusting the filter belt, and part of the gas inside the air bin 1 can be discharged to the toggling part, so that when the detection adjustment part controls the size of the airflow, the air pressure inside the air bin 1 can change, and then the monitoring adjustment part can correspondingly control the adjustment of the driven roller and the amplitude of the lower pressure roller of the adjustment part when detecting the change of the filter belt offset, so that the offset of the filter belt can be adjusted in real time.

[0021] 7. The gas in the toggle part enters the interior of the gas bin three through the gas pipe three, first blows the swing plate to rotate, and then contacts the pressure switch. The pressure switch can control the start of the electric heating wire. At the same time, the gas inside the gas bin three enters the interior of the drying bin through the gas distribution pipe, and then assists in heating the material on the upper end of the filter cloth to accelerate the evaporation efficiency of the water in the material. In the process of adjusting the filter belt to reset, the drying part assists in heating the material to evaporate the water therein, avoiding the situation in which the residual water in the material does not meet the standard due to the vacuum dehydration effect being affected when the filter belt and filter cloth are not reset during the adjustment process.

[0022] 8. During the adjustment process, the amount of gas passing through can change, and the air pressure in the gas chamber three changes, causing the force of the swing plate squeezing the pressure switch to change, thereby controlling the power of the heating wire and adjusting the drying effect in real time to avoid over-drying or incomplete drying.

DETAILED DESCRIPTION

[0033] In this embodiment, the air pump 201 is fixedly connected to the lower side of the inner middle part of the bracket 101, the upper ends of gear 1 205 and gear 2 206 are rotatably connected to the inner upper part of the cover plate 2045 through a rotating rod, the lower ends of the two racks 208 are slidably connected to the lower ends of the inner sides of the limiting bin 2046, the front and rear ends of the limiting bin 2046 are fixedly connected to the middle of the front and rear sides of the bracket 101, the middle parts of the two rotating shafts 2010 are rotatably connected to the middle of the upper ends of the front and rear sides of the bracket 101, the upper ends of the two torsion springs 2044 are fixedly connected to the middle of the upper ends of the inner front and rear sides of the bracket 101, and the middle outer peripheries of the two rotating wheels 2012 are rotatably connected to the middle of the front and rear sides of the filter belt 105.

[0034] Specifically, when one side of the filter belt 105 deviates outward, it squeezes the rotating wheel 2012 on one side, drives the rotating shaft 2010 to rotate through the swing frame 2011, thereby drives the rack 1 208 to move through the gear 4 209, and then drives the gear 3 207 on the upper or lower side to rotate, and then drives the gear 2 206 on the lower side to rotate through the rotating rod, and drives the T-shaped baffle 204 to rotate toward the swing frame 2011 on this side through the gear 1 205 and the rotating rod. At this time, the air outlet slot 203 is opened away from the swing frame 2011 on this side, and the gas is discharged from the air outlet away from the swing frame 2011 on this side, and enters the interior of the adjustment part. Through the cooperation of the toggle part, the filter belt 105 is adjusted to return to a normal state. On the contrary, when the other side of the filter belt 105 deviates outward, The gas is discharged from the exhaust port close to the side swing frame 2011, and the real-time monitoring of the filter belt 105 is realized through the monitoring and control part in the deviation adjustment mechanism 2. This process is mechanical transmission control, which avoids the sensitivity problem of the traditional monitoring sensor, resulting in the inability to send out the adjustment signal in time, causing the adjustment to be untimely. In addition, when the deviation of the filter belt 105 is greater, the rotating wheel 2012 on the squeezing side makes the swing frame 2011 rotate at a larger angle, so that more gas enters the adjustment part, the shifting part and the drying part, and accelerates the adjustment of the amplitude of the filter belt 105, thereby avoiding the slow adjustment recovery speed of the filter belt 105, resulting in the adjustment being unable to meet the amplitude of the filter belt 105, or the material is not completely dried at the upper end of the filter cloth 107.

The periphery is fixedly connected to the front and rear end outer periphery of the adjusting lower pressure roller 2019, the lower ends of the two universal bearing seats 1 2017 are fixedly connected with racks 2020, the lower ends of the right sides of the two racks 2020 are meshed with gears 5 2021, the right ends of the two gears 5 2021 are meshed with gears 6 2022, the lower ends of the two gears 6 2022 are meshed with racks 3 2023, and the upper ends of the right sides of the two racks 3 2023 are fixedly connected with sliding The movable seat 2024 and the upper ends of the two sliding seats 2024 are fixedly connected with the universal bearing seat 2025, the inner peripheries of the two universal bearing seats 2025 are fixedly connected to the outer peripheries of the front and rear ends of the driven roller 104, the right ends of the two universal bearing seats 2025 are fixedly connected with the limiting shaft 2026, the outer peripheries of the two limiting shafts 2026 are sleeved with springs 2027, and the lower ends of the two racks 3 2023 are slidably connected to the inner lower part of the sliding bin 2043.

[0036] In this embodiment, the lower ends of the two air pipes 2013 are fixedly connected to the inner periphery of the air outlet in the middle of the front and rear sides of the airflow bin 202, the lower ends of the two air bins 2014 are fixedly connected to the inner middle of the front and rear sides of the bracket 101, the middle outer peripheries of the two racks 2020 are slidably connected in the middle opening of the bracket 101, the middle parts of the two sets of gears 5 2021 and gear 6 2022 are rotatably connected to the inner left side of the sliding bin 2043 through a rotating rod, and the upper ends of the two sliding bins 2043 are fixedly connected to the right side of the inner lower part of the front and rear ends of the bracket 101.

[0037] In this embodiment, the lower end of the adjusting lower pressure roller 2019 is rotatably connected to the middle part of the inner lower wall of the filter belt 105, the inner peripheries of the two sliding seats 2024 are slidably connected to the outer peripheries of the middle part of the right end of the front and rear sides of the bracket 101, and the outer peripheries of the right ends of the two limiting shafts 2026 are slidably connected to the upper opening of the right end of the air pump 201.

[0038] Specifically, when gas enters the interior of the gas chamber 1 2014 from the gas pipe 1 2013 on the other side, the gas pressure inside the gas chamber 1 2014 increases. At this time, the gas pressure will force the piston plate 2015 to move downward, and drive the gear 5 2021 to rotate through the piston rod 2016, the universal bearing seat 1 2017 and the rack 2 2020, and then drive the rack 3 2023 to the rack 2 2020 in the sliding chamber 2043 through the gear 6 2022, and then drive the universal bearing seat 2 2025 to the rack 2 through the sliding seat 2024. 2020 moves, and finally drives the end of the driven roller 104 away from the filter belt 105 to rotate toward the rack 2 2020. At this time, due to the displacement of the end of the driven roller 104 away from the filter belt 105, the tension of the filter belt 105 changes, which will cause the filter belt 105 to move along the outer periphery of the driven roller 104 toward the end of the driven roller 104 away from the filter belt 105, thereby adjusting the filter belt 105 to reset. When the filter belt 105 is reset, the torsion spring 2044 drives the rotating shaft 2010 to reset. The air outlet groove 203 is blocked by the T-shaped baffle 204 again, the air pressure inside the air chamber 1 2014 returns to normal, and the rack 2020 is reset. The universal bearing seat 2025 resets the driven roller 104 through the tension and the spring 2027 on the periphery of the limit shaft 2026. Through the cooperation of the adjustment part and the monitoring control part in the deviation adjustment mechanism 2, it is realized that when the deviation of one side of the filter belt 105 is detected, the displacement of the other side of the driven roller 104 is adjusted in time, so that the filter belt 105 is automatically reset due to the change of tension. Compared with the traditional method of compressing the filter belt 105 to adjust the deviation of the filter belt 105, it will not cause damage to the filter belt 105, and the adjustment effect is better. At the same time, when the universal bearing seat 2017 on the side away from the deviation of the filter belt 105 descends, it drives the adjustment lower pressure roller 2019 to descend, and compresses the other side of the filter belt 105 to move downward, which not only makes the adjustment effect better, but also makes the filter belt 105 more effective and safer to adjust in the process of adjustment due to excessive deviation caused by large tension changes.

[0039] In this embodiment, the moving part includes air pipe 2028, air bin 2029, impeller 2030, gear 7 2031, knocking roller 1 2032, gear 8 2033 and knocking roller 2034. There are two air bins 2029, and the inner periphery of the air inlet end is fixedly connected with air pipe 2028. The inner upper parts of the two air bins 2029 are rotatably connected with the impeller 2030 through a rotating rod. The right ends of the two gears 7 2031 are fixedly connected with the knocking roller 1 2032 through a rotating rod. The lower ends of the two gears 7 2031 are meshed with gear 8 2033. The right ends of the two gears 8 2033 are fixedly connected with the knocking roller 2 2034 through a rotating rod. The left sides of the two gears 8 2033 are fixedly connected to the right side of the impeller 2030 through a rotating rod.

[0040] In this embodiment, the inner peripheries of the air outlet ends of the two air chambers 2029 are fixedly connected to the outer peripheries of the lower ends of the air pipes 3 2035, the left sides of the two air chambers 2029 are fixedly connected to the middle of the lower ends of the front and rear sides of the bracket 101, the upper ends of the two air pipes 2028 are fixedly connected to the right opening of the upper end of the air chamber 1 2014, and the left ends of the two gears 8 2033 are rotatably connected to the lower right end of the air chamber 2 2029 through a rotating rod.

[0041] Specifically, when gas enters the gas chamber 1 2014, part of the gas will enter the gas chamber 2 2029 from the gas pipe 2 2028, driving the impeller 2030 to rotate, and then driving the knocking roller 2034 to rotate through the rotating rod and the gear 8 2033, intermittently pushing the filter cloth 107 outward to deviate from the lower end of one side of the driven roller 104, so that when the filter belt 105 is adjusted, the filter cloth 107 is adjusted to move to the side away from the filter belt 105 and deviate from the driven roller 104, thereby adjusting the filter cloth 107 while adjusting the filter belt 105, avoiding the situation that the filter cloth 107 is torn and affects the filtering effect, and at the same time, the gear 8 2033 drives the filter cloth 107 to move outward to the lower end of the driven roller 104, so that when the filter belt 105 is adjusted, the filter cloth 107 is adjusted to avoid the situation that the filter cloth 107 is torn and affects the filtering effect, and at the same time, the gear 8 2033 drives the filter cloth 107 to move outward to the lower end of the driven roller 104, and then the filter cloth 107 is adjusted. Gear seven 2031 rotates, and then the filter belt 105 is offset to one side of the driven roller 104 through the knocking roller 2032, so that the auxiliary adjustment part can adjust the filter belt 105, improve the efficiency of adjusting the filter belt 105, and part of the gas inside the air tank 2014 can be discharged to the toggling part, so that when the detection adjustment part controls the size of the airflow, the air pressure inside the air tank 2014 can change, and then when the monitoring adjustment part detects that the offset of the filter belt 105 changes, the corresponding control adjustment part adjusts the amplitude of the driven roller 104 and the lower pressure roller 2019, so that the offset of the filter belt 105 can be adjusted in real time.

[0042] Working principle: Start the reduction motor 102, vacuum pump 1011 and double cleaning rollers 1016, add the gypsum solution that needs to be vulcanized and dehydrated to the left side of the upper end of the filter cloth 107 through the feed port 108, the reduction motor 102 drives the filter belt 105 to rotate through the driving roller 103 and the driven roller 104, the filter belt 105 cooperates with the tensioning roller 106 to drive the filter cloth 107 to rotate synchronously, the blocking roller 109 blocks the material so that the material can move to the right at the upper end of the filter cloth 107, the vacuum pump 1011, the connecting pipe 1012, the cyclone separator 1013, the vacuum pipe 1014 and the vacuum box 1015 generate suction at the lower end of the filter belt 105, and the water in the material passes through the filter cloth 107 and the filter belt 105 The air holes of the filter belt 105 suck the sewage into the cyclone separator 1013. After cyclone separation, the sewage is discharged through the lower end of the driving roller 103, and the gas is discharged through the connecting pipe 1012 and the vacuum pump 1011. When one side of the filter belt 105 deviates outward, it will squeeze the runner 2012 on one side, and drive the rotating shaft 2010 to rotate through the swing frame 2011, thereby driving the rack 1 208 to move through the gear 4 209, and then driving the upper or lower gear 3 207 to rotate, and then driving the lower gear 206 to rotate through the rotating rod, and driving the T-shaped baffle 204 to rotate toward the swing frame 2011 on this side through the gear 1 205 and the rotating rod. At this time, the air outlet slot 203 is opened away from the swing frame 2011 on this side, and the gas is discharged from the swing frame 2011 away from this side. The air is discharged from the outlet and enters the interior of the adjusting part. Through the cooperation of the toggle part, the filter belt 105 is adjusted to return to a normal state. On the contrary, when the other side of the filter belt 105 deviates outward, the gas is discharged from the exhaust port close to the swing frame 2011 on that side. Through the monitoring and control part in the deviation adjustment mechanism 2, the filter belt 105 is monitored in real time, and this process is mechanical transmission control, which avoids the problem of sensitivity of traditional monitoring sensors that lead to the failure to send adjustment signals in time, resulting in untimely adjustment. Moreover, when the deviation of the filter belt 105 is greater, the rotating wheel 2012 on one side is squeezed to make the swing frame 2011 rotate at a larger angle, so that more gas enters the adjusting part, the toggle part and the drying part, accelerating the adjustment of the filter belt. The amplitude of the belt 105 is adjusted to avoid the filter belt 105 adjusting and recovering slowly, which causes the adjustment to fail to meet the amplitude of the filter belt 105, or the material is not completely dried on the upper end of the filter cloth 107. When the gas enters the air bin 1 2014 from the air pipe 1 2013 on the other side, the air pressure inside the air bin 1 2014 increases. At this time, the air pressure will force the piston plate 2015 to move down, and drive the gear 5 2021 to rotate through the piston rod 2016, the universal bearing seat 1 2017 and the rack 2 2020, and then drive the rack 3 2023 to move toward the rack 2 2020 in the sliding bin 2043 through the gear 6 2022, and then drive the universal bearing seat 2 2025 to move toward the rack 2 2020 through the sliding seat 2024.Finally, the end of the driven roller 104 that is offset away from the filter belt 105 is driven to rotate toward the rack 2020. At this time, since the end of the driven roller 104 that is offset away from the filter belt 105 is displaced, the tension of the filter belt 105 changes, which will cause the filter belt 105 to move along the outer periphery of the driven roller 104 toward the end of the driven roller 104 that is offset away from the filter belt 105, thereby adjusting the filter belt 105 to reset. When the filter belt 105 is reset, the torsion spring 2044 drives the rotating shaft 2010 to reset, the air outlet groove 203 is re-blocked by the T-shaped baffle 204, the air pressure inside the air chamber 1 2014 returns to normal, the rack 2 2020 is reset, and the universal bearing seat 2 2025 is tensioned by the spring 2 27 on the outer periphery of the limit shaft 2026. By cooperating with the reset of the driven roller 104, through the cooperation of the adjustment part and the monitoring and control part in the deviation adjustment mechanism 2, it is achieved that when the deviation of one side of the filter belt 105 is detected, the displacement of the other side of the driven roller 104 is adjusted in time, so that the filter belt 105 is automatically reset due to the tension change. Compared with the traditional method of compressing the filter belt 105 to adjust the deviation of the filter belt 105, it will not cause damage to the filter belt 105, and the adjustment effect is better. At the same time, when the universal bearing seat 2017 on the side away from the deviation of the filter belt 105 descends, it drives the adjustment lower pressure roller 2019 to descend, and compresses the other side of the filter belt 105 to move downward, which not only makes the adjustment effect better, but also makes the filter belt 105 change greatly due to the tension change during the adjustment process. In the event of excessive deviation, adjustment is more effective and safer. When gas enters the air bin 1 2014, part of the gas will enter the air bin 2 2029 from the air pipe 2 2028, driving the impeller 2030 to rotate, and then driving the knocking roller 2034 to rotate through the rotating rod and the gear 8 2033, intermittently pushing the filter cloth 107 outward to deviate from the lower end of one side of the driven roller 104, so that when the filter belt 105 is adjusted, the filter cloth 107 is adjusted to move to the side away from the filter belt 105 that is deviated from the driven roller 104, thereby achieving the adjustment of the filter cloth 107 while adjusting the filter belt 105, avoiding the situation that the filter cloth 107 is torn and affects the filtering effect. At the same time, the gear 8 2033 drives the gear 7 203 1 rotates, and then the filter belt 105 is deflected out of one side of the driven roller 104 by the knocking roller 1 2032, so that the auxiliary adjustment part adjusts the filter belt 105, improves the efficiency of adjusting the filter belt 105, and part of the gas inside the gas chamber 1 2014 can be discharged into the toggling part, so that when the detection adjustment part controls the size of the airflow, the air pressure inside the gas chamber 1 2014 can be changed, and then the monitoring adjustment part can correspondingly control the amplitude of the adjustment driven roller 104 and the adjustment lower pressure roller 2019 of the adjustment part when monitoring the change of the deviation of the filter belt 105, so that the deviation of the filter belt 105 can be adjusted in real time, and the gas in the toggling part enters the interior of the gas chamber 3 2036 through the air pipe 3 2035,First, the swing plate 2037 is blown to rotate, and then the pressure switch 2039 is contacted. The pressure switch 2039 can control the electric heating wire 2042 to start. At the same time, the gas inside the gas chamber 3 2036 enters the interior of the drying chamber 2041 through the gas distribution pipe 2040, and then the material on the upper end of the filter cloth 107 is auxiliary heated to accelerate the evaporation efficiency of the water in the material. In the process of adjusting the filter belt 105 to reset, the drying part is used to auxiliary heat the material to evaporate the water therein, so as to avoid the situation that the residual water in the material does not meet the standard due to the vacuum dehydration effect being affected when the filter belt 105 and the filter cloth 107 are not reset during the adjustment process. In addition, during the adjustment process, the gas flow rate can change, and the air pressure in the gas chamber 3 2036 changes, resulting in the swing plate 2037 squeezing the pressure switch 2039. The force changes, and then the power of the electric heating wire 2042 is controlled to adjust the drying effect in real time to avoid excessive drying or incomplete drying.
