Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical equipment safety protection technical field, specifically, relate to a deviation detection device and horizontal vacuum belt filter. BACKGROUND

[0002] For chemical enterprises, horizontal vacuum belt filter plays an important role in material conveying and processing during production, improving production efficiency and automation level. In the process of lithium carbonate production from salt lake, it is necessary to separate solid and liquid and wash and remove impurities by horizontal vacuum belt filter.

[0003] The horizontal vacuum belt filter uses a belt to drive the filter cloth to rotate, and the belt deviation is one of the common faults of the horizontal vacuum belt filter. There are many causes of the fault, such as incorrect adjustment of the center during installation of the horizontal vacuum belt filter, or incorrect setting of the position and angle of the roller, which may cause the belt to deviate. During operation, the belt is subjected to external forces and uneven feeding, which will cause the belt to be unbalanced, resulting in deviation. In addition, uneven tension of the belt is also a common cause. When the belt tension is uneven, the belt will tend to deviate towards the side with less tension. After long-term use of the equipment, wear of the roller, carrier roller and carrier roller frame will cause the belt to be unstable and prone to deviation. Of course, environmental factors such as temperature change and humidity may also affect the stability of the belt, causing deviation. In order to avoid these problems, regular inspection and maintenance of the horizontal belt machine are needed to ensure its normal operation. In addition, these factors should also be fully considered during design and installation to reduce the possibility of belt deviation. Belt deviation may cause the following adverse effects: belt damage or unstable material conveying, reduced production capacity, affecting the quality of lithium carbonate products, reducing their purity and consistency.

[0004] Currently, there are several methods to correct the belt deviation, such as: regular inspection and adjustment of the belt tension to make the belt tension appropriate so that the belt can run in the correct position; since the key components such as rollers and carrier rollers may wear out and cause the belt to deviate, these components can be replaced in time to avoid production delays caused by belt deviation; regular cleaning of material accumulation to avoid belt deviation and blockage, so that the material can be conveyed normally; additional devices such as edge guides and guides can help the belt to stay in a stable position; if the belt deviation is caused by unbalanced equipment, the belt running direction can be adjusted to make it closer to the center of gravity of the equipment. Before dealing with the belt deviation, the specific cause of the belt deviation needs to be determined, but the existing horizontal vacuum belt filter cannot automatically detect whether the belt is deviating, and the staff cannot find that the belt has deviated from the predetermined track in time, which makes it impossible to take timely corrective measures, which may cause the belt to be damaged and cause economic losses.

DETAILED DESCRIPTION

[0027] It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict. The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0028] The ore in the salt lake contains lithium carbonate, and the belt conveyor plays a key role in the process of extracting lithium carbonate from the salt lake. First of all, it transports the lithium carbonate-containing ore from the mining site or extraction equipment to the subsequent processing equipment, ensuring that the ore can quickly and efficiently enter the next production link. The belt conveyor can also send larger ore into the crushing equipment to break it into smaller particles, helping to improve the efficiency of ore processing. The crushed ore needs to be screened to separate ore of different particle sizes. The belt conveyor can send the ore into the screening equipment to realize the automated screening process. When the ore needs to be temporarily stored, the belt conveyor can transport it to the designated stacking area for convenient stacking and management of the ore. After the lithium carbonate production process, the obtained lithium carbonate product can also be transported to the storage area or loading equipment by the belt conveyor, preparing for subsequent market sales. However, the belt conveyor will also have some problems. For example, belt deviation is caused by many reasons, such as incorrect centering during installation, or incorrect position and angle setting of the roller. In addition, external forces during operation, such as uneven material accumulation, wind influence, etc., can also cause the belt to deviate. Uneven tension of the belt is also a common cause. Belt deviation can cause a series of adverse effects. First of all, it will cause unstable material conveying, which will affect the production capacity. If the raw materials such as lithium carbonate cannot be accurately and timely transported to the target location, it will affect the continuous operation of the production line and reduce the production efficiency. Secondly, belt deviation may also cause uneven or chaotic distribution of materials, which may affect the quality of lithium carbonate products. In the long run, belt deviation may increase the risk of equipment failure, resulting in additional downtime and disruption of production plans. At present, there is no device on the market that can automatically detect belt deviation and alarm, which makes it impossible to discover that the belt has deviated from the predetermined track in time.

[0029] In order to solve the above problems, in combination with the Figures 1 to 6As shown, the utility model provides a kind of deviation detection device 80, which comprises: mounting seat 10, with installation cavity;Trigger mechanism 20, including trigger assembly 21 and rotating trigger piece 22, trigger assembly 21 is installed in installation cavity, trigger assembly 21 has first trigger state and second trigger state, when trigger assembly 21 is in first trigger state, trigger assembly 21 can send alarm signal, when trigger assembly 21 is in second trigger state, trigger assembly 21 can send shutdown signal, rotating trigger piece 22 is rotationally connected with mounting seat 10, the rotation axis of rotating trigger piece 22 extends along horizontal direction, part rotating trigger piece 22 is located in installation cavity, the part of rotating trigger piece 22 in installation cavity is configured to be able to abut with trigger assembly 21, to make trigger assembly 21 can be in first trigger state or second trigger state;Detection wheel 30, is installed in rotating trigger piece 22 away from mounting seat 10 one end, detection wheel can rotate relative to rotating trigger piece 22, and the rotation axis of detection wheel 30 is arranged with the rotation axis of rotating trigger piece 22 Angle.

[0030] In the embodiment, along the direction perpendicular to the conveying direction of the conveying belt 101, the conveying belt 101 has a first side and a second side arranged oppositely, the deviation detection device 80 is installed on the first side and / or the second side of the conveying belt 101, when the conveying belt 101 is not deviated and normally conveyed, the conveying belt 101 does not contact the detection wheel 30, when the conveying belt 101 is deviated, the conveying belt 101 will touch and push the detection wheel 30, since the detection wheel 30 is installed on the rotating trigger piece 22, the detection wheel 30 will drive the rotating trigger piece 22 to rotate, in the process of rotating of the rotating trigger piece 22, the part of the rotating trigger piece 22 in the installation cavity will abut with the trigger assembly 21, so that the trigger assembly 21 is in the first trigger state or the second trigger state, so that the worker can find that the conveying belt 101 deviates from the predetermined track in time, so as to take measures to correct in time.

[0031] The trigger mechanism 20 is composed of a trigger assembly 21 and a rotating trigger 22, and can send different signals according to the deviation degree of the conveying belt 101. When the conveying belt 101 is slightly deviated, the conveying belt 101 pushes the detection wheel 30 to rotate at a small angle, the rotating trigger 22 rotates at a small angle, and the trigger assembly 21 is in a first trigger state. At this time, the trigger assembly 21 can send an alarm signal, so that the staff can find that the conveying belt 101 deviates from the predetermined track in time, so as to take timely measures to correct, thereby avoiding serious consequences caused by long-term neglect. When the conveying belt 101 is seriously deviated, the conveying belt 101 pushes the detection wheel 30 to rotate at a large angle, the rotating trigger 22 rotates at a large angle, and the trigger assembly 21 is in a second trigger state. At this time, the trigger assembly 21 can send a stop signal to make the conveying belt 101 stop conveying. Through the above setting, the deviation detection device 80 can respond differently under different deviation conditions, and the flexibility of the deviation detection device 80 is improved.

[0032] The detection wheel 30 can protect the rotating trigger 22, avoid direct contact between the rotating trigger 22 and the conveying belt 101, and prevent the rotating trigger 22 from being worn and damaged, thereby prolonging the service life of the rotating trigger 22. In addition, the surfaces of different conveying belts 101 have different friction effects on the rotating trigger 22. Through the setting of the detection wheel 30, different specifications of the conveying belt 101 can be better adapted to, so that the rotating trigger 22 can maintain a relatively stable working state. Moreover, the rotating direction of the detection wheel 30 is consistent with the conveying direction of the conveying belt 101, which can reduce the friction of the conveying belt 101 and avoid damage to the conveying belt 101.

[0033] It should be noted that if the salt mine factory uses the deviation detection device 80 of the present application, the safety and production efficiency of the equipment can be greatly improved, the equipment damage can be avoided, the risk of production interruption and safety accidents can be reduced, and the artificial inspection work can be reduced, and the automation level of the production line can be improved.

[0037] In the present embodiment, the first end of the second connecting part 2222 is rotatably connected with the second end of the first connecting part 2221, so that the angle between the first connecting part 2221 and the second connecting part 2222 is adjustable, and since the detection wheel 30 is installed on the second connecting part 2222, the position of the detection wheel 30 relative to the conveying belt 101 can be adjusted to adapt to conveying belts 101 of different widths without the need to replace the entire device or make complicated adjustments, thereby improving the applicability of the deviation detection device 80.

[0042] In one embodiment, the locking part 40 is a bolt.

[0043] In combination with the Figures 1 to 6 As shown in the utility model, in one embodiment of the utility model, the trigger assembly 21 comprises a first trigger part 211, the first trigger part 211 comprises a first trigger piece 2111, a first contact piece 2112, a second contact piece 2113 and a first elastic piece 2114, the first trigger piece 2111 is sleeved on the rotating trigger section 221, one end of the first elastic piece 2114 is connected with the top wall of the mounting cavity, the other end of the first elastic piece 2114 is connected with the first contact piece 2112, the second contact piece 2113 is located on the side of the first contact piece 2112 away from the first elastic piece 2114, the second contact piece 2113 is connected with the mounting base 10, the side of the first contact piece 2112 and the second contact piece 2113 facing each other is provided with a first convex part 2115, two first convex parts 2115 are correspondingly and spaced apart, the outer circumferential side of the first contact piece 2112 is provided with a first insulation section 2116, the first insulation section 2116 is located on the moving path of the first trigger piece 2111, when two first convex parts 2115 contact under the pressure of the first trigger piece 2111, the trigger assembly 21 is in the first trigger state.

When the first trigger 2111 rotates to contact the first insulating section 2116 and continues to rotate, the first trigger 2111 presses down the first contact 2112, so that the first contact 2112 can move to the direction where the second contact 2113 is located against the elastic force of the first elastic member 2114, until the first protrusion 2115 on the first contact 2112 and the first protrusion 2115 on the second contact 2113 are in contact under pressure.

When the conveying belt 101 deviates from the predetermined running track and a large deviation occurs, the edge of the conveying belt 101 touches the detection wheel 30 and pushes the detection wheel 30, and then pushes the rotating trigger section 221 to rotate, so that the rotating trigger section 221 drives the second trigger piece 2121 to rotate, when the second trigger piece 2121 rotates to contact the second insulation section 2126 and continues to rotate, the second trigger piece 2121 presses down the third contact piece 2122, so that the third contact piece 2122 can move away from the fourth contact piece 2123 against the elastic force of the second elastic piece 2124, until the second convex part 2125 on the third contact piece 2122 is separated from the second convex part 2125 on the fourth contact piece 2123, when two second convex parts 2125 are completely separated from each other, the contact circuit of the trigger assembly 21 is disconnected, at this time, the trigger assembly 21 is in the second trigger state and sends a stop signal.
