Abstract
Description
Technical Field
[0001] The invention relates to the technical field of conveying devices, in particular to a gypsum slurry conveying device capable of automatically adjusting scraping materials. Background Art
[0002] Belt conveyor is a friction-driven machine that transports materials in a continuous manner. It is mainly composed of a frame, conveyor belt, rollers, drums, tensioning devices, transmission devices, etc. It can form a material conveying process from the initial feeding point to the final unloading point on a certain conveying line. In the belt conveying of gypsum board slurry, since it is often necessary to convey slurry with a certain humidity and viscosity, it is often necessary to use a corresponding scraper device to clean the conveyor belt to prevent the slurry from adhering to the outer surface of the belt and affecting the normal operation of the belt conveyor.
[0003] The existing scraper device needs to regularly clean the gypsum remaining on the scraper end during the scraping process. Generally, the cleaning methods for the gypsum remaining on the scraper device are divided into manual cleaning and mechanical cleaning. However, both manual cleaning and mechanical cleaning have shortcomings, which are specifically divided into the following shortcomings:
[0004] 1. Although manual cleaning does not require consumption of other energy and only requires manual physical labor, it requires downtime for processing, does not utilize the continuous production of the entire production line, and has low cleaning efficiency.
[0005] 2. Although mechanical cleaning has high cleaning efficiency and does not require shutdown, the cleaning equipment needs to be driven by a separate driving source. The increase in driving sources not only increases the size of the cleaning equipment, but also increases energy consumption and production costs.

[0021] As a preferred solution of the present invention, a sealing telescopic sleeve is provided at the connection between the connecting rod and the activity chamber, and the sealing telescopic sleeve is automatically telescopically deformed to meet the change of the position of the connecting rod.

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0052] like Figure 1 As shown, a gypsum slurry conveying device with automatic adjustment of scraping material comprises a conveyor belt mechanism 1, two scraping material mounting frames 3, a scraper 4, an intermittent flushing component 5 and a transmission component 6;
[0053] The conveyor belt mechanism 1 is used to convey the gypsum slurry. Both ends of the driving roller in the conveyor belt mechanism 1 extending out of the side wall of the frame are connected to driving gears 2;
[0054] Two scraper mounting frames 3 are respectively mounted on both sides of the frame in the conveyor belt mechanism 1;
[0055] The scraper 4 has one end rotatably connected to the side walls of the two scraper mounting frames 3 and the other end in contact with the conveyor belt in the conveyor belt mechanism 1;
[0056] The intermittent flushing assembly 5 is installed between the two scraper mounting frames 3 and can store and transport water;
[0057] The transmission assembly 6 is mounted on the scraper mounting frame 3, one end of which is connected to the driving gear 2 through a chain belt, and the other end is connected to the intermittent flushing assembly 5 through a hinge. The transmission assembly 6 can drive the intermittent flushing assembly 5 to intermittently spray cleaning water toward the scraper 4;
[0058] The intermittent flushing assembly 5 includes a piston-type flushing box 51 and two connecting pieces 52. The inner cavity of the piston-type flushing box 51 is connected with a water storage chamber 511, an active chamber 512 and a spray chamber 513 in sequence. The inner cavity of the active chamber 512 is slidably connected with a piston 517 hingedly connected to the two connecting pieces 52 respectively.
[0059] Driven by the transmission assembly 6, the two connecting parts 52 drive the two pistons 517 to guide the water in the water storage chamber 511 into the active chamber 512 or to guide the water in the active chamber 512 into the injection chamber 513 and spray it out; so that the cleaning water in the piston-type flushing box 51 is flushed along the flushing port directly toward the contact point between the scraper 4 and the conveyor belt.
[0060] When the conveyor belt transports gypsum slurry, the conveyor belt rotates continuously. During the rotation process, the slurry on the conveyor belt is scraped by the scraper 4. The slurry on the conveyor belt is cleaned up by the scraper 4. The cleaned up slurry gradually accumulates on the head of the scraper 4 over time. The accumulated slurry will affect the later scraping of the scraper 4 and requires manual cleaning. However, manual cleaning is time-consuming and labor-intensive, and also requires shutdown. The device of the present application can automatically flush the slurry accumulated on the head of the scraper 4 while the conveyor belt is running, so as to achieve the effect of cleaning the scraper 4, thereby improving the effect of the scraper 4 on cleaning the conveyor belt, and the intermittent flushing component 5 does not need to be separately provided with an external drive device, but only needs to use the driving force of the transmission roller in the conveyor belt mechanism 1.
[0061] Since the water in the three chambers of the piston-type flushing box 51 can be in a circulating state, the inner cavity of the piston-type flushing box 51 should be designed with a channel for the water to circulate.
[0062] Specifically, Figure 3 As shown, the top of the water storage chamber 511 is connected to an external water inlet pipe 514, and water channels 515 are provided at the connections between the water storage chamber 511 and the activity chamber 512 and between the activity chamber 512 and the injection chamber 513. The inner cavity of the injection chamber 513 is provided with a plurality of spray holes 516 along its length direction.
[0063] The spray hole 516 mainly serves to discharge water, and the main power for the water sprayed out of the spray hole 516 comes from the transmission component 6. Under the action of the continuous rotation of the transmission component 6, the two pistons 517 reciprocate close to or away from each other, so that the water in the injection chamber 513 is sprayed out along the spray hole 516.
[0064] Specifically, the two connecting members 52 each include a connecting rod 521 and a reinforcing rod 522, and the connecting rod 521 and the reinforcing rod 522 are hinged to each other.
[0065] One end of the reinforcing rod 522 away from the hinge point is hinged to the piston 517 , and one end of the connecting rod 521 away from the hinge point is hinged to the transmission assembly 6 .
[0066] Further, such as Figure 1-3 As shown, the transmission assembly 6 includes a limit seat 61, a driven gear 62, a rotating shaft 63 and a rotating disk 64; the limit seat 61 is installed on the scraper mounting frame 3; the rotating shaft 63 passes through the inner cavity of the limit seat 61, and both ends extend out of the side wall of the limit seat 61, one end of the rotating shaft 63 is connected to the driven gear 62, and the other end is connected to the rotating disk 64; the driven gear 62 is connected to the driving gear 2 through a tooth chain, and the disc surface of the rotating disk 64 is hinged to the connecting rod 521.
[0067] When the conveyor belt transports the slurry, the scraper 4 fits tightly under the tail of the conveyor belt, and when the conveyor belt rotates, the transmission roller that drives the conveyor belt to rotate drives the driving gear 2 to rotate, and the driving gear 2 is linked to the driven gear 62 through a toothed chain, so the moving driven gear 62 rotates synchronously with the transmission roller, and the driven gear 62 drives the turntable 64 to rotate through the rotating shaft 63. The connecting rod 521 connected between the turntable 64 and the piston-type flushing box 51 continuously changes its position with the rotation of the turntable 64, that is, when the connecting rod 521 is at the highest point of the turntable 64, the connecting rod 521 pushes the piston in the piston-type flushing box 51 forward to complete the water spraying action, conversely, when the connecting rod 521 is at the lowest point of the turntable 64, the connecting rod 521 pulls the piston in the piston-type flushing box 51 back to complete the water absorption action, thereby intermittently spraying water to clean the top of the scraper 4.
[0068] Since the piston-type flushing box 51 is designed with a multi-chamber structure, before use, the turntable 64 is at the lowest point of the turntable 64. At this time, the water storage chamber 511, the active chamber 512 and the injection chamber 513 are all in the state of maximum volume. Then the external water inlet pipe 514 is connected to the external water source to fill water so that the water fills the entire piston-type flushing box. When the conveyor belt moves, the turntable 64 also rotates. At this time, the two connecting rods 521 at the lowest point move synchronously toward the highest point. During the movement, the connecting rod 521 pushes the piston 11 forward. As the two pistons 11 approach each other, the water in the active chamber 512 is squeezed, so that the pressure of the active chamber 512 and the injection chamber 513 increases, thereby continuously pumping the water in the active chamber 512. The water is introduced into the injection chamber 513 through the water channel 515, and the water in the injection chamber 513 is quickly ejected from the spray hole 516 under the action of boost. The spray direction of the spray hole 516 is perpendicular to the contact point between the scraper 4 and the conveyor belt, ensuring that the injected water is directly facing the contact point between the scraper 4 and the conveyor belt. When the connecting rod 521 moves to the highest point, the boost is maximum. At this time, as the conveyor belt continues to move, the connecting rod 521 moves toward the lowest point. During the movement, the connecting rod 521 pulls the piston 11 back. At this time, the pressure in the inner cavity of the active chamber 512 is constantly decreasing, and the water in the water storage chamber 511 is sucked into the active chamber 512 and the injection chamber 513 through the water channel 515, thereby completing the intermittent movement of water absorption and water spraying during the rotation of the turntable 64.
[0069] A one-way valve is installed in the water channel 515. Under the action of the one-way valve, the water in the water storage chamber 511, the activity chamber 512 and the injection chamber 513 can only flow in one direction.
[0070] As the connecting rod 521 rotates with the turntable 64, the distance between the connecting rod 521 and the active chamber 512 will also change. Since the active chamber 512 needs to be sealed to prevent air or water leakage, which would affect the normal operation of the piston flushing box 51, a sealing structure needs to be provided at the connection between the connecting rod 521 and the active chamber 512.
[0071] Specifically, Figure 3 As shown, a sealing telescopic sleeve 8 is provided at the connection between the connecting rod 521 and the activity chamber 512, and the sealing telescopic sleeve 8 automatically telescopes and deforms to meet the change of the position of the connecting rod 521, wherein the sealing telescopic sleeve 8 is a louver-type silicone sealing sleeve or other louver-type sealing sleeve, and the sealing sleeve needs to be made of a tough material that is resistant to tensile force and wear, so as to increase the service life of the sealing telescopic sleeve 8.
[0072] When the conveyor belt is in contact with the scraper 4 for a long time, the scraper is prone to wear and tear, and a gap is easily generated between the scraper 4 and the conveyor belt. The gap will make it impossible to clean a small amount of slurry, and the slurry adhering to the conveyor belt will affect the subsequent transportation of gypsum slurry. In order to avoid this phenomenon.
[0073] The scraper mounting frame 3 includes an L-shaped fixing frame 31, which is fixed to the frame in the conveyor belt mechanism 1 by fixing bolts, and the right angle of the L-shaped fixing frame 31 is in contact with the frame in the conveyor belt mechanism 1, and a rotating shaft 35 is rotatably connected between the transverse sections of the two L-shaped fixing frames 31, and the rotating shaft 35 is connected to the scraper 4;
[0074] Two support seats 32 are fixedly connected to the vertical section of the L-shaped fixing frame 31 from top to bottom in sequence, and an elastic adjustment component 7 is connected between the support seat 32 at the lower part and the rotating shaft 35;
[0075] Further, such as Figure 1-2 As shown, the elastic adjustment assembly 7 includes a sleeve 71, a guide rod 72 and a contraction spring 73. The sleeve 71 is sleeved on the end of the rotating shaft 35, the guide rod 72 is connected to the sleeve 71, and the guide rod 72 is connected to the support seat 32 through the contraction spring 73.
[0076] The outer surface of the vertical end of the L-shaped fixing frame 31 is provided with a mounting groove 74 for the sleeve 71 to move. Under the elastic force of the contraction spring 73, the guide rod 72 pulls the rotating shaft 35 to rotate, so that the scraper 4 rotates synchronously with the rotating shaft 35, thereby making the scraper 4 close to the conveyor belt.
[0077] When the scraper 4 scrapes the slurry on the conveyor belt, the contraction spring 73, under the action of its own tension, makes the guide rod 72 have a tendency to rotate upward. The guide rod 72 with the upward rotation tendency pulls the sleeve 71 to rotate, and the sleeve 71 drives the rotating shaft 35 to rotate. Since the rotating shaft 35 is fixedly connected to the scraper 4, the movement trend of the scraper 4 is the same as the movement trend of the rotating shaft 35. The rotating shaft 35 with the upward rotation tendency has the effect of driving the scraper 4 to always be close to the conveyor belt.
[0078] During the scraping process, the slurry scraped off the conveyor belt mainly falls onto the head of the scraper 4. Even under the flushing of the piston-type flushing box, there will be some slurry remaining on the scraper head.
[0079] In actual use, considering that the device is installed on the frame of the conveying mechanism, it is necessary to consider the installation issue, that is, the installation relationship between the piston flushing box 51 and the elastic adjustment component 7, so that when achieving their respective effects, they will not affect their respective normal work.
[0080] Specifically, Figure 1-2As shown, the scraper mounting frame 3 includes an L-shaped fixing frame 31, which is fixed to the frame in the conveyor belt mechanism 1 by fixing bolts, and the right angle of the L-shaped fixing frame 31 is in contact with the frame in the conveyor belt mechanism 1, and the transverse sections of the two L-shaped fixing frames 31 are rotatably connected to the rotating shaft 35;
[0081] When installing the device, the two L-shaped fixing frames 31 are respectively installed on the frame by fixing bolts, and the rotating shaft 35 is connected between the two L-shaped fixing frames 31. Since the piston-type flushing box and the elastic adjustment component are both installed on the L-shaped fixing frames 31, and the scraper is also located between the two L-shaped fixing frames 31, the piston-type flushing box must be opposite to the scraper 4.
[0082] Further, such as Figure 1 As shown, two support seats 32 are fixedly connected to the vertical section of the L-shaped fixing frame 31 from top to bottom in sequence, and the support seat 32 at the lower part is connected to the rotating shaft 35 through an elastic adjustment component. A fixing plate 33 is arranged between the two lower support seats 32, and a plurality of support frames 34 are fixedly connected to the top of the fixing plate 33. The other end of the support frame 34 is connected to the piston-type flushing box 51 to support the piston-type flushing box 51.
[0083] A limit seat 61 is fixedly connected to the upper support seat 32 . A rotating shaft 63 is rotatably connected to the limit seat 61 . Both ends of the rotating shaft 63 extend out of the side walls of the limit seat 61 .
[0084] By arranging the elastic adjustment components on both sides of the piston-type flushing box, the functions of the two are realized without mutual interference. Two sets of support seats 32 are arranged on the two L-shaped fixing frames 31, one of which is used to install the piston-type flushing box 51, so that the piston-type flushing box 51 is elevated, thereby ensuring that the spray hole 516 in the piston-type flushing box 51 is located directly above the scraper 4, thereby facilitating the cleaning of the contact point between the scraper and the conveyor belt, and the other set of support seats 32 is used to install the turntable 64, the driven gear 62 and the rotating shaft 63.
[0085] Specifically, Figure 4 As shown, the scraper 4 includes a straight section 41 and an arc section 42, and the arc section 42 is integrally formed on the straight section 41;
[0086] The arc segment 42 is bent toward the conveyor belt in the conveyor belt mechanism 1 to fit the conveyor belt. The side of the arc segment 42 away from the conveyor belt is a slope structure with a high top and a low bottom to facilitate the sliding of the gypsum slurry.
[0087] The curved side of the arc segment 42 of the scraper 4 meets the curved posture of the tail of the conveyor belt, so as to better fit on the conveyor belt, and the side of the arc segment 42 away from the conveyor belt is a slope structure with a high top and a low bottom. On the one hand, the scraper 4 can maintain a linear contact state with the conveyor belt, so as to better scrape the material. On the other hand, the slope structure can make the slurry slide better under the flushing action of the piston flushing box.
[0088] It can be understood that the scraper 4 is fixed to the rotating shaft 35 by fixing bolts, that is, a circular groove which is sleeved with the rotating shaft 35 is formed at the bottom of the straight section 41 along its length direction, and the fixing bolt passes through the circular groove and is fixed to the rotating shaft.
[0089] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
