Description

Technical Field

[0001] The present invention relates to the field of industrial salt processing, and specifically relates to an industrial salt belt conveyor with an anti-loosening mechanism. Background Art

[0002] Industrial salt is one of the most basic raw materials in the chemical industry. Its main components include sodium chloride, sodium nitrite, etc. It is known as the "mother of the chemical industry."

[0003] A search revealed an invention patent application with authorization publication number CN205940086U, which discloses a recovery-type salt production system comprising a salt drying system, a post-bed iodization system, and a powdered salt recovery system. The salt drying system comprises a wet material belt conveyor, a drying device, and a cyclone dust collector. The drying device comprises a material inlet, a material outlet, and an air outlet. The cyclone dust collector comprises an air inlet and a powdered salt outlet. The end of the wet material belt conveyor is connected to the material inlet of the drying device, the air inlet of the cyclone dust collector is connected to the air outlet of the drying device, the powdered salt recovery system is connected to the powdered salt outlet of the cyclone dust collector, and the post-bed iodization system is connected to the material outlet of the drying device. The present utility model adds a powdered salt recovery system to recover powdered salt, which is then dissolved for use in ion-exchange membrane caustic soda. This system can replace 50,000 tons of industrial salt for domestic use annually, reducing production costs.

[0004] In the existing technology, a belt conveyor is needed to transport industrial salt. As the belt conveyor is used for a long time, the conveyor belt on the belt conveyor will inevitably become loose, which will cause the transmission efficiency of the conveyor belt to decrease in subsequent use, affecting the transportation rate of industrial salt. In addition, in order to ensure the stability of power, the belt conveyor will also transmit the belt to the roller, thereby providing multiple sets of drives for the transmission of the conveyor belt. However, as the use time increases, the belt will inevitably become loose. Utility Model Content

[0005] The purpose of this solution is to provide an industrial salt belt conveyor with an anti-loosening mechanism to solve the problem of loosening of the conveyor belt during long-term use in the existing technology, and at the same time solve the problem of loosening of the transmission belt.

[0006] In order to achieve the above-mentioned purpose, the present invention provides an industrial salt belt conveyor with an anti-loosening mechanism, comprising a crossbeam, wherein there are two crossbeams and they are arranged in parallel. Support legs are installed at the bottom of each crossbeam, and a driving roller 1 is provided at both ends between the two crossbeams, and the end of the driving roller 1 is rotatably connected to the crossbeam. The ends of the two driving rollers 1 are connected through a transmission mechanism, and a tensioning mechanism is provided on the transmission mechanism, wherein a driving motor is installed at one end of one driving roller 1, and a driving roller 2 is provided below the driving roller 1 in parallel, and the end of the driving roller 2 is rotatably connected to the support leg. A conveyor belt is installed on the driving roller 2 and the driving roller 1, and tensioning rollers are provided at both ends of the bottom of the conveyor belt, and the end of the tensioning roller is rotatably installed on a connecting frame, and the other end of the connecting frame is rotatably installed on the support leg through a rotating shaft. An inclined electric push rod 1 is provided below the connecting frame, and one end of the electric push rod 1 is rotatably connected to the support leg through a rotating shaft, and the other end of the electric push rod 1 is rotatably installed in a U-shaped seat, and the U-shaped seat and the connecting frame are fixed near one end of the tensioning roller.

[0007] The principle of this solution is that when in use, as industrial salt is placed on the conveyor belt for transportation, if the conveyor belt becomes loose, the electric push rod 1 can be driven to push the connecting frame to rotate upward, so that the tensioning roller can act on the bottom of the conveyor belt and push it upward, so that the conveyor belt is tensioned again, ensuring that the conveyor belt is close to the drive roller and will not become loose. If the transmission mechanism becomes loose, the tensioning mechanism can be driven to act on the transmission mechanism to ensure stable transmission between the drive rollers.

[0008] The technical effect of this solution is that through the rotation of a pair of connecting frames of the electric push rod, the tensioning roller can drive the bottom of the conveyor belt to move up and down, thereby tensioning the conveyor belt during transmission, ensuring that the conveyor belt is close to the drive roller to avoid loosening.

[0009] Furthermore, a plurality of spaced support rollers are provided between the two drive rollers, the ends of which are rotatably connected to the crossbeam. The support rollers act on the inner side of the conveyor belt to support the top of the conveyor belt, thereby ensuring the stability of the industrial salt during transportation on the conveyor belt and preventing it from falling off the side of the conveyor belt due to depressions in the conveyor belt.

[0010] Furthermore, the transmission mechanism includes pulleys coaxially mounted on the ends of the first drive roller and connected by a belt, wherein the tensioning mechanism is disposed on the belt. The belt drives the first drive rollers at both ends to rotate synchronously, providing multiple sets of power for the transmission of the conveyor belt.

[0011] Furthermore, the tensioning mechanism includes a support wheel located below and corresponding to the belt. The support wheel is rotatably mounted within a U-shaped frame. A second electric push rod is mounted at the bottom of the U-shaped frame and is fixed to a support leg. The lifting and lowering of the support wheel acts on the belt, thereby tensioning the belt transmission and preventing it from loosening.

[0012] Furthermore, the surfaces of the first and second drive rollers are covered with anti-skid pads, and the anti-skid sleeves are rough rubber sleeves. The anti-skid pads provided on the first and second drive rollers increase the friction between the drive rollers and the conveyor belt, allowing the conveyor belt to move effectively when the drive rollers rotate.

[0013] Furthermore, the surface of the tensioning roller is covered with an anti-skid pad, and the anti-skid cover is a rough rubber cover. The anti-skid pad provided on the tensioning roller increases the friction between the tensioning roller and the conveyor belt, ensuring that the conveyor belt always drives the tensioning roller to rotate during transmission, reducing the probability of friction between the conveyor belt and the tensioning roller, and reducing wear on the conveyor belt.

[0014] Furthermore, the ends of the first and second driving rollers are both provided with limit plates, which limit the position of the conveyor belt on the driving rollers to prevent the conveyor belt from shifting during long-term use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The embodiment is basically as shown in the attached Figure 1-Figure 4As shown: An industrial salt belt conveyor with an anti-loosening mechanism, including a crossbeam 1, there are two crossbeams 1 and they are arranged in parallel, and support legs 2 are installed at the bottom of each crossbeam 1, and a driving roller 3 is provided at both ends between the two crossbeams 1, and the end of the driving roller 3 is rotatably connected to the crossbeam 1, and the ends of the two driving rollers 3 are connected through a transmission mechanism 11, and a tensioning mechanism 18 is provided on the transmission mechanism 11, and a driving motor 10 is installed at one end of one driving roller 3, and a driving roller 2 4 is provided below the driving roller 3 in parallel, and the end of the driving roller 2 4 is rotatably connected to the support leg 2, and a conveyor belt 5 is installed on the driving roller 2 4 and the driving roller 3, and the surfaces of the driving roller 3 and the driving roller 2 4 are wrapped with anti-slip pads, and the anti-slip sleeves are rough surfaces. The rough rubber sleeve increases the friction between the driving roller and the conveyor belt 5 through the anti-slip pads arranged on the driving roller 1 3 and the driving roller 2 4, so that the conveyor belt 5 can be driven to move well when the driving roller rotates; the ends of the driving roller 1 3 and the driving roller 2 4 are both installed with limit plates, and the position of the conveyor belt 5 on the driving roller is limited by the limit plates to avoid the conveyor belt 5 from shifting during long-term use; a plurality of support rollers 17 arranged at intervals are provided between the two driving rollers 1 3, and the ends of the support rollers 17 are rotatably connected to the crossbeam 1. The support rollers 17 act on the inner side of the conveyor belt 5 to support the top of the conveyor belt 5, thereby ensuring the stability of industrial salt during transportation on the conveyor belt 5 and preventing it from falling from the side of the conveyor belt 5 due to the depression of the conveyor belt 5.

[0022] like Figure 1 and Figure 2 As shown, the transmission mechanism 11 includes a pulley 12, which is coaxially mounted on the end of the driving roller 3, and the pulleys 12 are connected by a belt 13, wherein the tensioning mechanism 18 is arranged on the belt 13, and the driving rollers 3 at both ends are driven to rotate synchronously through the transmission of the belt 13, thereby providing multiple sets of power for the transmission of the conveyor belt 5; the tensioning mechanism 18 includes a support wheel 14, which is located below the belt 13 and corresponds to the belt 13, and the support wheel 14 is rotatably mounted in the U-shaped frame 15, and an electric push rod 2 16 is installed at the bottom of the U-shaped frame 15, and the electric push rod 2 16 is fixed to the support leg 2. The lifting and lowering of the support wheel 14 acts on the belt 13, and also tensions the transmission of the belt 13 to avoid loosening.

[0023] like Figure 1 、 Figure 2 、 Figure 3As shown, tensioning rollers 6 are provided at both ends of the bottom of the conveyor belt 5, and the end of the tensioning roller 6 is rotatably mounted on the connecting frame 7, and the other end of the connecting frame 7 is rotatably mounted on the supporting leg 2 through a rotating shaft. An inclined electric push rod 8 is provided below the connecting frame 7, and one end of the electric push rod 8 is rotatably connected to the supporting leg 2 through a rotating shaft, and the other end of the electric push rod 8 is rotatably mounted in a U-shaped seat 9. The U-shaped seat 9 is fixed to one end of the connecting frame 7 close to the tensioning roller 6. The surface of the tensioning roller 6 is wrapped with an anti-slip pad, and the anti-slip sleeve is a rubber sleeve with a rough surface. The anti-slip pad arranged on the tensioning roller 6 increases the friction between the tensioning roller 6 and the conveyor belt 5, ensuring that the conveyor belt 5 always drives the tensioning roller 6 to rotate during transmission, reducing the probability of friction between the conveyor belt 5 and the tensioning roller 6, and reducing the wear of the conveyor belt 5.

[0024] The specific implementation process of the present utility model is as follows: when in use, as industrial salt is placed on the conveyor belt 5 for transportation, if the conveyor belt 5 becomes loose, the electric push rod 8 can be driven to push the connecting frame 7 to rotate upward, so that the tensioning roller 6 can act on the bottom of the conveyor belt 5 and push it upward, so that the conveyor belt 5 is tensioned again, ensuring that the conveyor belt 5 is close to the drive roller and will not become loose. If the transmission mechanism 11 becomes loose, the tensioning mechanism 18 can be driven to act on the transmission mechanism 11 to ensure stable transmission between the drive rollers 3.

[0025] This solution uses the electric push rod 8 to rotate the connecting frame 7, so that the tensioning roller 6 can drive the bottom of the conveyor belt 5 to move up and down, thereby tensioning the conveyor belt 5 during transmission, ensuring that the conveyor belt 5 is close to the drive roller to avoid loosening.

[0026] The above is only an embodiment of the present invention, and the commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
