Description

Technical Field

[0002] In washing plants, mines, and various industrial production outdoor working environments, belt conveyors, as key equipment for material transportation, bear the heavy responsibility of transporting various materials. When the conveyed materials contain moisture, the moisture is very easy to freeze on the conveyor belt of the belt conveyor in a low temperature environment. Once the conveyor belt freezes, the friction between the material and the conveyor belt is reduced due to the ice, causing the material and the conveyor belt to slip, which in turn causes the material to pile up. For belt conveyors that use multiple drives, ice on the conveyor belt will cause the friction between the conveyor belt and the drive roller to be unbalanced, resulting in slippage, which affects the stable operation of the belt conveyor.

[0003] In some scenarios, the ice on the surface of the conveyor belt of the belt conveyor is cleaned manually and regularly. However, this method is not only inefficient and difficult to complete the cleaning of the conveyor belt in a short time, but also seriously lacks real-time performance and cannot effectively deal with the frozen materials as soon as possible, which leads to the worsening of the conveyor belt icing problem and hinders the continuous and stable operation of the belt conveyor.

[0026] like Figure 1 As shown, the deicing device 10 provided in the embodiment of the present invention can be used in Figure 1 In the belt conveyor scenario shown, Figure 1 The belt conveyor shown in the figure comprises a driving roller 1, a conveyor belt 2, a redirecting roller 3 and a deicing device 10. The conveyor belt 2 moves at a speed V in cooperation with the driving roller 1 and the redirecting roller 3. The deicing device 10 of the belt conveyor in the embodiment of the present invention can be installed at Figure 1 The position shown, that is, the deicing device 10 is installed below the conveyor belt 2. Of course, according to the actual application scenario, the deicing device 10 in the embodiment of the present invention can be installed at other positions, and the embodiment of the present invention is not limited here.

[0027] For example, Figure 2 and Figure 3 As shown, the deicing device 10 includes an ultrasonic detector 100, a first deicing mechanism 200 and a controller. The first deicing mechanism 200 includes a pressure roller 201 and an ice-breaking assembly 202, which are respectively arranged on the upper and lower sides of the conveyor belt of the belt conveyor. When the ultrasonic detector 100 detects that the surface of the conveyor belt is frozen, the controller controls the pressure roller 201 and the ice-breaking assembly 202 to squeeze the ice area of ​​the conveyor belt.

[0028] Specifically, after the ultrasonic detector 100 detects ice on the surface of the conveyor belt, it transmits the detected ice area and the ice thickness of the ice area to the controller in the form of a signal. The controller controls the ice breaking assembly 202 to move toward the conveyor belt based on the ice thickness. After the ice breaking assembly 202 reaches the target position, it presses the ice area with the pressure roller 201 to crush the ice in the ice area. Among them, the pressure roller 201 is used to press the conveyor belt to ensure that when the ice breaking assembly 202 presses the conveyor belt, there is sufficient pre-tightening force between the ice breaking assembly 202 and the conveyor belt.

[0029] For example, Figure 3As shown, the ice breaking assembly 202 includes an ice breaking blade head 2020, a blade head bracket 2021 and a first oil cylinder 2022. The ice breaking blade head 2020 is fixed to the blade head bracket 2021, and the blade head bracket 2021 is fixed to the first oil cylinder 2022. The first oil cylinder 2022 can be extended and retracted up and down to drive the ice breaking blade head 2020 away from or close to the conveyor belt. Among them, the pressure roller 201 is installed at one end of the bracket 2010, and the other end of the bracket 2010 can be fixed to the box. The ice breaking blade head 2020 is fixed to the blade head bracket 2021, one end of the first oil cylinder 2022 is fixed to the blade head bracket 2021, and the other end of the first oil cylinder 2022 is fixed to the box. When the first oil cylinder 2022 receives the command of the controller and moves, it pushes the blade head bracket 2021. The blade bracket 2021 drives the ice-breaking blade head 2020 to move toward the conveyor belt so that there is sufficient pre-tightening force between the ice-breaking blade head 2020 and the pressure roller 201 and squeezes the ice area of ​​the conveyor belt to crush the ice.

[0030] Furthermore, as the roller body of the driving pressure roller 201 of the conveyor belt rotates along with the conveyor belt, the degree of crushing of ice in the icing area is increased, thereby improving the ice crushing effect, so that more crushed ice falls off the conveyor belt faster.

[0031] In this way, through the first ice-breaking mechanism provided by the embodiment of the present invention, the controller can control the oil cylinder to squeeze the ice-breaking blade head and the pressure roller against each other to crush the ice, so that the ice cubes fall from the conveyor belt, thereby clearing the ice area in real time, improving the efficiency of clearing ice on the conveyor belt, and further saving manpower and material resources.

[0032] For example, Figure 4 As shown, the ice breaker head 2020 may be a sawtooth-shaped structure, and the top of each tooth may be a flat structure to avoid damage to the conveyor belt and extend the service life of the conveyor belt.

[0033] For example, Figure 2 and Figure 5 As shown, the de-icing device of the belt conveyor also includes a second de-icing mechanism 400. The first de-icing mechanism 200 and the second de-icing mechanism 400 are arranged in sequence along the running direction of the conveyor belt; the second de-icing mechanism 400 includes a first ice-breaking ball array 401 and a second ice-breaking ball array 402 respectively arranged on the upper and lower sides of the conveyor belt of the belt conveyor, and the controller controls the first ice-breaking ball array 401 and the second ice-breaking ball array 402 on the upper and lower sides of the conveyor belt to reciprocate and crush the ice area on the conveyor belt after being de-iced by the first de-icing mechanism 200.

[0034] Specifically, if Figure 5As shown, the first ice-breaking ball array 401 includes an upper bracket 4010 and a plurality of first ice-breaking ball components 4011 fixed to the upper bracket 4010, each of the first ice-breaking ball components 4011 includes a second oil cylinder 4012 and a first ball 4013; one end of the second oil cylinder 4012 is fixed to the upper bracket 4010, and the first ball 4013 is arranged at the other end of the second oil cylinder 4012 and is rollingly connected to the other end of the second oil cylinder 4012, and the controller controls the second oil cylinder 4012 to extend and retract up and down to drive the first ball 4013 to reciprocate and impact and roll and crush the conveyor Belt; the second ice-breaking ball array 402 includes a lower bracket 4020 and a plurality of second ice-breaking ball components 4021 fixed to the lower bracket 4020, each second ice-breaking ball component 4021 includes a third oil cylinder 4022 and a second ball 4023; one end of the third oil cylinder 4022 is fixed to the lower bracket 4020, the second ball 4023 is arranged at the other end of the third oil cylinder 4022 and is rollingly connected to the other end of the third oil cylinder 4022, and the controller controls the third oil cylinder 4022 to extend and retract up and down to drive the second ball 4023 to reciprocate and roll to crush the conveyor belt.

[0035] Specifically, one end of the upper bracket 4010 and the lower bracket 4020 are respectively fixed on the box body, and the other ends of the upper bracket 4010 and the lower bracket 4020 are respectively used to fix the first ice-breaking ball component 4011 and the second ice-breaking ball component 4021. When the second oil cylinder 4012 and the third oil cylinder 4022 receive the command from the controller, they push the first ball 4013 and the second ball 4023 to reciprocate and roll to crush the conveyor belt. Among them, the ultrasonic detector 100 can also detect the density of the crushed ice on the surface of the conveyor belt after being squeezed by the first deicing mechanism 200, and the controller adjusts the expansion and contraction frequency of the second oil cylinder 4012 and the third oil cylinder 4022 and the rolling frequency of the first ball 4013 and the second ball 4023 based on the crushed ice density. Among them, the greater the density of the crushed ice, the greater the expansion and contraction frequency of the second oil cylinder 4012 and the third oil cylinder 4022 and the rolling frequency of the first ball 4013 and the second ball 4023.

[0036] In this way, through the second de-icing mechanism provided in the embodiment of the present invention, the controller controls the oil cylinder to drive the first ice-breaking ball array and the second ice-breaking ball array in the second de-icing mechanism to reciprocately impact and crush the iced area on the conveyor belt after the ice is broken by the first de-icing mechanism. The vibration and crushing of the first ice-breaking ball array and the second ice-breaking ball array can be used to separate the residual ice adhering to the conveyor belt, thereby effectively improving the strength and effect of clearing ice accumulated on the conveyor belt.

[0037] For example, Figure 2 and Figure 6As shown, the de-icing device of the belt conveyor also includes an ice scraping and cleaning mechanism 500. Along the running direction of the conveyor belt, the first de-icing mechanism 200, the second de-icing mechanism 400 and the ice scraping and cleaning mechanism 500 are arranged in sequence; the ice scraping and cleaning mechanism 500 includes an ice scraping blade head 501, a blade head bracket 502, a fixing frame 503, a retractable mechanism 504 arranged on the fixing frame 503 and a direction adjustment mechanism 505 arranged on the retractable mechanism 504. The ice scraping blade head 501 is arranged at one end of the blade head bracket 502, and the other end of the blade head bracket 502 is arranged on the direction adjustment mechanism 505. By adjusting the direction of the direction adjustment mechanism 505 to drive the blade head bracket 502 to change direction, the controller controls the retractable mechanism 504 to retract relative to the conveyor belt.

[0038] Specifically, if Figure 6 As shown, the telescopic mechanism 504 includes a fourth oil cylinder 5040 and a first mounting portion 5041, one end of the oil cylinder 5040 is fixed to the fixing frame 503, and the other end of the fourth oil cylinder 5040 is fixed to the first mounting portion 5041. The direction adjustment mechanism 505 includes a second mounting portion 5050, a rotating portion 5051 and a fixing member 5052, a part of the second mounting portion 5050 is fixed to the inside of the first mounting portion 5041, another part of the second mounting portion 5050 extends out of the first mounting portion 5041, the rotating portion 5051 is arranged on the second mounting portion 5050 extending out of the first mounting portion 5041 and can rotate relative to the second mounting portion 5050, a part of the second mounting portion 5050 extending out of the first mounting portion 5041 is provided with a plurality of holes, and the fixing member 5052 passes through the holes to press the rotating portion 5051.

[0039] More specifically, the fixing member 5052 may be a bolt pair, and the bolt pair may pass through the opening on the second mounting portion 5050 and enter the interior of the second mounting portion 5050. The cutter head bracket 502 passes through the second mounting portion 5050 and is fixedly connected to the rotating portion 5051, and the rotating portion 5051 may drive the cutter head bracket 502 to rotate at any angle. When the rotating portion 5051 needs to drive the cutter head bracket 502 to rotate, the bolt pair may be loosened so that the rotating portion 5051 may rotate in the second mounting portion 5050. When the direction of the cutter head bracket 502 needs to be fixed, the bolt pair may be tightened to clamp the rotating portion 5051, so that the rotating portion 5051 cannot rotate.

[0040] Furthermore, after the ice area on the conveyor belt passes through the first de-icing mechanism 200 and the second de-icing mechanism 400, the controller controls the fourth cylinder 5040 of the ice scraping and cleaning mechanism 500 to move toward the conveyor belt. When the fourth cylinder 5040 moves toward the conveyor belt, it drives the first mounting part 5041 to move, thereby driving the second mounting part 5050, the blade bracket 502 and the ice scraper head 501 to move toward the conveyor belt, so that a pressing force is generated between the conveyor belt and the ice scraper head 501. As the conveyor belt rotates, the ice scraper head 501 cleans the residual ice on the conveyor belt.

[0041] Further, in order to make the ice scraper head 501 press against the conveyor belt, Figure 2 As shown, the embodiment of the present invention is further provided with a clamping mechanism 502. When the ice scraper head 501 is pressed against the surface of the conveyor belt, the clamping mechanism 502 and the ice scraper head 501 are pressed against each other so that a clamping force is generated between the conveyor belt and the ice scraper head 501. As the conveyor belt rotates, the ice scraper head 501 cleans the residual ice on the conveyor belt. The clamping mechanism 502 can be any fixing member, such as a pressure plate, etc., one end of which can be set on the inner side wall of the top of the box body 600, and the other end can be a flat structure and close to the conveyor belt to cooperate with the ice scraper head 501.

[0042] In this way, the embodiment of the present invention is provided with an ice scraping and cleaning mechanism, and the ice scraper head of the ice scraping and cleaning mechanism is pressed against the conveyor belt to scrape off the residual ice on the conveyor belt, thereby further improving the de-icing effect and de-icing strength on the conveyor belt. In addition, the direction adjustment mechanism in the ice scraping and cleaning mechanism can adaptively adjust the direction of the ice scraper head according to the angle of the surface of the conveyor belt, so that the direction of the ice scraper head is more suitable for the angle of the conveyor belt in the current scene, thereby improving the removal effect and strength of residual ice on the conveyor belt in different scenes.

[0043] Further, such as Figure 2 As shown, the deicing device of the belt conveyor also includes a box body 600, a drainage mechanism 700 and a heating mechanism 800. The ultrasonic detector 100, the first deicing mechanism 200, the second deicing mechanism 400 and the ice scraping and cleaning mechanism 500 are all arranged inside the box body 600; the heating mechanism 800 is used to heat to melt the ice that falls on the conveyor belt and discharge it through the drainage mechanism 700.

[0044] Specifically, the drainage mechanism 700 can be a drainage hole, or a combination of a water pump and a drainage hole. When the drainage mechanism 700 is a drainage hole, it can be set at the bottom of the box 600, and the ice dropped from the conveyor belt can be directly discharged from the inside of the box 600 after being heated and melted by the heating mechanism 800. When the drainage mechanism 700 is a combination of a drainage hole and a water pump, the drainage hole can be set on the side wall of the box 600, and the pipeline of the water pump can be connected to the outside of the box 600 through the drainage hole, and the ice dropped from the conveyor belt can be heated and melted by the heating mechanism 800 and can be pumped out from the inside of the box 600 by the water pump. Among them, the heating mechanism 800 can be a heating rod.

[0045] It is worth noting that the controller can be arranged inside or outside the box 600, and the embodiment of the present invention does not limit its arrangement position.

[0046] It is worth noting that the ultrasonic detector 100, the first deicing mechanism 200, the second deicing mechanism 400 and the ice scraping and cleaning mechanism 500 are fixed on the fixing frame 601 inside the box 600, and the fixing frame 601 can be a hollow structure to ensure that the ice falling off the conveyor belt can fall into the bottom of the box 600. In addition, the pressure roller 201 is installed at one end of the bracket 2010, and the other end of the bracket 2010 can be fixed on the inner side wall of the top of the box 600 to achieve a fixing effect. In order to make the schematic diagram more concise, the embodiment of the present invention is not illustrated for the time being. Furthermore, the other end of the upper bracket 4010 is also fixed on the inner side wall of the top of the box 600 to achieve a fixing effect. In order to make the schematic diagram more concise, the embodiment of the present invention is not illustrated for the time being.

[0047] In addition, as shown in FIG. 2 , a window 602 may be provided on the box 600 , through which the user can view the situation inside the box 600 in real time, and can perform maintenance on the various mechanisms inside the box 600 .

[0048] The embodiment of the present invention detects the surface of the conveyor belt of the belt conveyor through an ultrasonic detector. After the ultrasonic detector detects that the surface of the conveyor belt of the belt conveyor is frozen, the controller controls the pressure roller and the ice-breaking assembly of the first de-icing mechanism to squeeze the ice area of ​​the conveyor belt against each other, so that the ice area of ​​the conveyor belt breaks. In this way, after ice forms on the conveyor belt, the ice area can be broken immediately. The broken ice falls off the conveyor belt and slides off the conveyor belt during the operation of the conveyor belt. The real-time performance and removal efficiency are high, which avoids the problem of further deterioration of the ice problem of the conveyor belt and ensures the continuous and stable operation of the belt conveyor.

[0049] Based on the same inventive concept of the deicing device for a belt conveyor provided in the above embodiment, the present invention also discloses a deicing method for a belt conveyor, such as Figure 7As shown, Figure 7 A flow chart of a deicing method for a belt conveyor provided in an embodiment of the present invention, wherein the deicing method for a belt conveyor disclosed includes: Step S701, obtaining a first detection signal of an ultrasonic detector, where the ultrasonic detector is used to detect the surface of a conveyor belt of a belt conveyor.

[0050] Specifically, the ultrasonic detector in the embodiment of the present invention can detect the surface of the conveyor belt in real time. When ice forms on the upper surface of the conveyor belt, the ultrasonic detector can detect information such as the ice area and ice thickness on the surface of the conveyor belt.

[0051] Step S702, when the first detection signal indicates that the surface of the conveyor belt is frozen, control the pressure roller and ice-breaking assembly of the first deicing mechanism to press the frozen area of ​​the conveyor belt against each other.

[0052] Specifically, after the ultrasonic detector detects ice on the surface of the conveyor belt, the ice-breaking assembly can be controlled to move relative to the conveyor belt, thereby cooperating with the pressure roller to press the conveyor belt. As the conveyor belt is driven, the roller body of the pressure roller rotates and cooperates with the ice-breaking assembly to squeeze and crush the ice stuck on the conveyor belt, causing it to fall off the conveyor belt.

[0053] Furthermore, as an optional embodiment of the present invention, controlling the pressure roller and ice-breaking assembly of the first de-icing mechanism to squeeze the ice area of ​​the conveyor belt against each other includes: analyzing the first detection signal to obtain the ice thickness of the ice area on the conveyor belt; determining the target distance between the pressure roller and the blade surface of the ice-breaking blade of the ice-breaking assembly according to the ice thickness; and controlling the extension and retraction of the first oil cylinder of the ice-breaking assembly based on the distance so that the distance between the pressure roller and the blade surface of the ice-breaking blade of the ice-breaking assembly reaches the target distance.

[0054] Specifically, the ultrasonic detector in the embodiment of the present invention can detect the ice thickness in the icing area. The distance between the pressure roller and the blade surface of the icebreaker blade of the icebreaking assembly changes accordingly with the ice thickness. After the ultrasonic detector detects the ice thickness in the icing area, the controller determines the target distance between the pressure roller and the blade surface of the icebreaker blade of the icebreaking assembly according to the ice thickness. Among them, the target distance between the pressure roller and the blade surface of the icebreaker blade of the icebreaking assembly in the embodiment of the present invention can be 10% smaller than the ice thickness in the icing area to improve the deicing effect.

[0055] In this way, the embodiment of the present invention adjusts the distance between the pressure roller and the ice-breaking blade head of the ice-breaking assembly by the ice thickness, so that the distance between the pressure roller and the blade head surface of the ice-breaking blade head of the ice-breaking assembly can adapt to the ice thickness of the ice-forming area, avoiding the problem of the conveyor belt being stuck due to the ice thickness being too thick and the distance between the pressure roller and the blade head surface of the ice-breaking blade head of the ice-breaking assembly being too small, or avoiding the problem of poor deicing effect due to the ice thickness being too thin and the distance between the pressure roller and the blade head surface of the ice-breaking blade head of the ice-breaking assembly being too large. In this way, the embodiment of the present invention adjusts the distance between the pressure roller and the ice-breaking blade head of the ice-breaking assembly by the ice thickness, thereby improving the deicing effect, strength and reliability.

[0056] The embodiment of the present invention detects the surface of the conveyor belt of the belt conveyor through an ultrasonic detector. After the ultrasonic detector detects that the surface of the conveyor belt of the belt conveyor is frozen, the pressure roller and the ice-breaking assembly of the first de-icing mechanism are controlled to mutually squeeze the ice area of ​​the conveyor belt, so that the ice area of ​​the conveyor belt breaks. In this way, after ice forms on the conveyor belt, the ice area can be broken immediately. The broken ice falls off the conveyor belt and slides off the conveyor belt during the operation of the conveyor belt. The real-time performance and removal efficiency are high, which avoids the problem of further deterioration of the ice problem of the conveyor belt and ensures the continuous and stable operation of the belt conveyor.

[0057] Optionally, as an optional embodiment of the present invention, when the first detection signal indicates that the surface of the conveyor belt is frozen, after controlling the pressure roller and ice-breaking assembly of the first de-icing mechanism to squeeze the ice area of ​​the conveyor belt against each other, the method also includes: acquiring a second detection signal of the ultrasonic detector; analyzing the second detection signal to obtain the density of crushed ice in the ice area after being squeezed by the first de-icing mechanism; determining the frequency of the first ice-breaking ball array and the second ice-breaking ball array of the second de-icing mechanism according to the density of the crushed ice; and controlling the first ice-breaking ball array and the second ice-breaking ball array to reciprocately impact and crush the ice area on the conveyor belt after being squeezed by the first de-icing mechanism based on the frequency.

[0058] Specifically, after the ice area passes through the first de-icing mechanism, there are still some residual crushed ice adhering to the conveyor belt, and the ultrasonic detector can detect the density of the crushed ice adhering to the conveyor belt. Then the controller adjusts the frequency of the first ice-breaking ball array and the second ice-breaking ball array according to the density of the crushed ice. Among them, the greater the density of the crushed ice, the greater the frequency of the first ice-breaking ball array and the second ice-breaking ball array. Among them, when adjusting the frequency of the first ice-breaking ball array and the second ice-breaking ball array, the frequency of the reciprocating impact of the first ball and the second ball on the conveyor belt can be adjusted by adjusting the telescopic frequency of the second cylinder and the third cylinder. And / or adjust the rolling frequency of the first ball and the second ball to adjust the rolling frequency of the first ball and the second ball rolling the conveyor belt.

[0059] In this way, through the second de-icing mechanism provided in the embodiment of the present invention, the controller controls the oil cylinder to drive the first ice-breaking ball array and the second ice-breaking ball array in the second de-icing mechanism to reciprocately impact and crush the iced area on the conveyor belt after the ice is broken by the first de-icing mechanism. The vibration and crushing of the first ice-breaking ball array and the second ice-breaking ball array can be used to separate the residual ice adhering to the conveyor belt, thereby effectively improving the strength and effect of clearing ice accumulated on the conveyor belt.
