The feeder 1 is driven by a vibration motor, in order to prevent the feeder 1 from being damaged by vibration impact during operation, a certain space needs to be reserved between the feeding port 11 of the feeder 1 and the discharge port 221 of the cooler 2. However, during the material conveying process, a large amount of dust spills out from the reserved gaps, the dust of the material splashes to the production site, which not only threatens the health of the on-site operators, but also hides the danger of production safety, and the risk of dust explosion is correspondingly increased.

[0032] The utility model provides a kind of sealing mechanism and conveying device, as shown in Figure Figure 1 The conveying device includes cooler 2, feeder 1 and the sealing mechanism provided by the utility model, the sealing mechanism can be arranged between cooler 2 and feeder 1, for sealing the discharge port 221 of cooler 2 and the feeding port 11 of feeder 1. The conveying device seals the discharge port 221 and the feeding port 11 through the sealing mechanism, which can prevent material leakage, reduce waste and improve conveying stability.

[0033] As shown in Figure Figure 1As shown, the sealing mechanism includes a base 3, a first stopper 41 and two second stoppers 42, one end of the base 3 is sealingly connected with the feeding port 11, the other end is flexibly sealingly connected with the outer wall of the discharge pipe 22, the first stopper 41 and the second stopper 42 are both arranged around the discharge pipe 22, the first stopper 41 is fixedly connected with the outer wall of the discharge pipe 22, and the second stopper 42 is fixedly connected with the inner wall of the base 3 in the vertical direction, one first stopper 41 is arranged between every two second stoppers 42, and any first stopper 41 and the two second stoppers 42 adjacent thereto are distributed in a Z shape in the vertical direction.

[0034] The sealing mechanism of the embodiment is arranged between the feeder 1 and the cooler 2, the material in the cooler 2 flows to the feeding port 11 of the feeder 1 through the discharge pipe 22, one end of the base 3 is sealingly connected with the feeding port 11, and the other end is flexibly connected with the outer wall of the discharge pipe 22, which can adapt to the vibration of the feeder 1 and the displacement caused by the vibration, and any first stopper 41 fixedly connected with the outer wall of the discharge pipe 22 and the two second stoppers 42 fixedly connected with the inner wall of the base 3 adjacent thereto are distributed in a Z shape in the vertical direction, which can effectively seal the gap between the discharge pipe 22 and the base 3, reduce the leakage and dust raising of the material during the conveying process, and ensure the smooth conveying of the material.

[0035] The conveying device of the embodiment realizes the sealing communication between the discharge port 221 of the cooler 2 and the feeding port 11 of the feeder 1, effectively avoids the leakage during the conveying process of the material, reduces the material loss, prevents the dust overflow and dust raising, avoids the pollution to the working environment, and protects the health of the operators. In addition, the sealing connection can also reduce the entry of external air into the conveying link, prevent the oxidation and deterioration of the material, and maintain the quality of the material. The arrangement of the sealing mechanism optimizes the connection between the cooler 2 and the feeder 1, ensures the smooth conveying process, and significantly improves the overall performance of the conveying device.

[0036] In the embodiment, the number of first stoppers 41 is one, and the number of second stoppers 42 is two, in other embodiments, the number of first stoppers 41 can be two, and correspondingly, the number of second stoppers 42 can be three, the number of first stoppers 41 can be three, and correspondingly, the number of second stoppers 42 can be four, which is not limited here.

[0037] As Figure 1As shown, the extension direction of the first stopper 41 forms a first preset angle with the vertical direction, and the extension direction of the second stopper 42 forms a second preset angle with the vertical direction, and the first preset angle is equal to the second preset angle. The inclined arrangement of the first stopper 41 and the second stopper 42 increases the path length of the movement of the material dust, effectively prevents the leakage of the material and the dust, and in addition, when the feeder 1 runs and vibrates or displaces, the inclined structure can better adapt to the changes, maintain stable sealing effect, reduce material loss, improve working environment, and ensure efficient operation of the conveying device.

[0038] Specifically, the extension direction of the first stopper 41 is defined as the direction of the first stopper 41 from the fixed connection end of the discharge pipe 22 to the unfixed end, and the extension direction of the first stopper 41 forms a first preset angle with the vertical direction in Figure 1 The extension direction of the second stopper 42 is defined as the direction of the second stopper 42 from the fixed connection end of the base 3 to the unfixed end, and the extension direction of the second stopper 42 forms a second preset angle with the vertical direction in Figure 1 The first preset angle is equal to the second preset angle, and any one first stopper 41 and two second stoppers 42 adjacent thereto are distributed in a Z-shaped manner along the vertical direction, and the first preset angle is equal to the second preset angle. The cross design greatly prolongs the dust movement path and can more effectively block the dust from escaping, greatly improving the sealing effect.

[0039] In this embodiment, the first preset angle and the second preset angle are both 45 degrees, and in other embodiments, the first preset angle and the second preset angle can be 30 degrees, 35 degrees, 40 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, 85 degrees, 90 degrees, etc., which are not limited here.

[0040] As shown in Figure 1 The first stopper 41 is constructed as a first loop, and the inner circle of the first loop is fixedly connected with the outer wall of the discharge pipe 22; and the second stopper 42 is constructed as a second loop, and the outer circle of the second loop is fixedly connected with the inner wall of the base 3. On the one hand, the first stopper 41 and the second stopper 42 both adopt a loop structure, which fully surrounds the clamping space of the discharge pipe 22 and the base 3, forms a multi-layer sealing barrier, greatly improves the blocking ability of the dust, ensures that the material is in a tightly sealed environment during the conveying process, eliminates dust leakage, and creates a clean production environment. On the other hand, any one first loop and two loops adjacent thereto are distributed in a Z-shaped manner along the vertical direction. This ingenious cross layout greatly prolongs the dust movement path and effectively suppresses the dust rising when the feeder 1 runs and vibrates.

[0041] In the embodiment, the discharge pipe 22 is constructed as a first square cylinder, and the base 3 is constructed as a second square cylinder. The base 3 includes four rectangular steel plates with equal height and width, and the four rectangular steel plates are welded to form a hollow second square cylinder with open ends. The base 3 has sufficient strength and stability to withstand the vibration and pressure during the operation of the feeder 1, ensuring the stability of the structure. The welding process tightly combines the steel plates to form a continuous sealing structure, effectively preventing dust leakage.

[0042] In the embodiment, the first return-shaped piece includes four trapezoidal connecting plates, each of which is provided with an upper base, a first waist, a second waist, and a lower base. The four upper bases of the four trapezoidal connecting plates are fixedly connected to the four sides of the outer wall of the first square cylinder. The first waist of any trapezoidal connecting plate is connected to the second waist of the adjacent trapezoidal connecting plate. The four trapezoidal connecting plates are constructed as the first return-shaped piece. That is, the inner circle of the first return-shaped piece is fixedly connected to the outer wall of the first square cylinder, and the outer circle of the first return-shaped piece is spaced from the inner wall of the second square cylinder, effectively extending the dust movement path and preventing dust from overflowing. At the same time, when the feeder 1 vibrates, the reserved space can provide a space for buffering vibration and displacement.

[0043] In the embodiment, the second return-shaped piece includes four trapezoidal connecting plates, each of which is provided with an upper base, a first waist, a second waist, and a lower base. The four lower bases of the four trapezoidal connecting plates are fixedly connected to the four sides of the inner wall of the second square cylinder. The first waist of any trapezoidal connecting plate is connected to the second waist of the adjacent trapezoidal connecting plate. The four trapezoidal connecting plates are constructed as the second return-shaped piece. That is, the outer circle of the second return-shaped piece is fixedly connected to the inner wall of the second square cylinder, and the inner circle of the second return-shaped piece is spaced from the outer wall of the first square cylinder, extending the dust escape path and effectively preventing dust from overflowing, significantly improving the sealing performance. When the feeder 1 vibrates during operation, the reserved space acts as a buffer space, which can buffer vibration and displacement and avoid the inner circle of the second return-shaped piece directly rubbing the outer wall of the first square cylinder, reducing wear and tear, thereby prolonging the service life of the discharge pipe 22 and ensuring the sealing and stability of material conveying.

[0044] In other embodiments, the base 3 can be constructed as a first cylinder, and the discharge pipe 22 can be constructed as a second cylinder. Correspondingly, the first return-shaped piece and the second return-shaped piece can both be constructed as a circular ring, which is not specifically limited here.

[0045] As Figure 1As shown, the sealing mechanism further comprises a flexible sealing member 5, a first end of the flexible sealing member 5 being connected to the outer wall of the discharge pipe 22, and a second end being connected to the end of the base 3 away from the feeding port 11. On the one hand, the flexible sealing member 5 can effectively seal the gap between the discharge pipe 22 and the base 3, reduce dust or gas leakage, reduce material loss and avoid environmental pollution. On the other hand, the flexible material can buffer the vibration and displacement generated during the operation of the feeder 1, reduce the wear of the components, ensure the stability of the sealing, ensure the stable conveying of the cooled material to the feeder 1, and improve the continuity and reliability of the production.

[0046] As shown in Figure 1 As shown, the sealing mechanism further comprises a first fastener (not shown in the figure), a second fastener (not shown in the figure), a first sealing pressing plate 61 and a second sealing pressing plate 62. The first sealing pressing plate 61 is provided with a first through hole, and the first fastener is sequentially arranged through the first through hole, the first end of the flexible sealing member 5, and fixedly connected with the outer wall of the discharge pipe 22. The second sealing pressing plate 62 is provided with a second through hole, and the second fastener is sequentially arranged through the second through hole, the second end of the flexible sealing member 5, and fixedly connected with the outer wall of the base 3. The first sealing pressing plate 61 tightly presses the first end of the flexible sealing member 5 against the outer wall of the discharge pipe 22 by means of the first fastener, and the second sealing pressing plate 62 tightly presses the second end of the flexible sealing member 5 against the outer wall of the base 3 by means of the second fastener, effectively improving the sealing performance, reducing the risk of leakage during material conveying, preventing the flexible sealing member 5 from falling off and being damaged during the vibration of the feeder 1, prolonging the service life of the flexible sealing member 5, reducing the maintenance cost, stably conveying the material to the feeder 1, and improving the reliability of the sealing mechanism.

[0047] In this embodiment, the sealing mechanism comprises four first sealing pressing plates 61 and four second sealing pressing plates 62, so as to tightly seal the first end of the flexible sealing member 5 against the four faces of the outer wall of the first square cylinder, and the second end of the flexible sealing member 5 against the four faces of the outer wall of the second square cylinder.

[0048] In this embodiment, the first sealing pressing plate 61 and the second sealing pressing plate 62 are flat steel, and are coated with colored paint on the surface, so as to facilitate the management. A 6mm shaft drill bit is used to drill first through holes with equal spacing in the first sealing pressing plate 61, and a 6mm shaft drill bit is used to drill second through holes with equal spacing in the second sealing pressing plate 62, so as to facilitate the later installation and use, and improve the installation efficiency.

[0049] In this embodiment, the flexible sealing member 5 is made of high-temperature-resistant material. The cooler 2 processes high-temperature calcined materials. The flexible sealing member 5 made of high-temperature-resistant material will not deform, age or lose sealing performance under high-temperature environment, and can continuously ensure the sealing effect between the discharge pipe 22 and the base 3, prevent high-temperature dust and hot gas leakage, and reduce safety risks. At the same time, the high-temperature-resistant property prolongs the service life of the flexible sealing member 5, reduces downtime caused by frequent replacement of the flexible sealing member 5, reduces maintenance costs, ensures that the material conveying link is not affected by high temperature, and continues to operate stably.

[0050] In this embodiment, the flexible sealing member 5 is a high-temperature-resistant filter bag. The high-temperature-resistant filter bag is cut to an appropriate size and connected to the outer wall of the discharge pipe 22 and the end of the base 3 away from the feed inlet 11, respectively, which effectively prevents material leakage and maintains a certain looseness during installation to avoid excessive tension. The flexible sealing member 5 can better adapt to the relative displacement and vibration between the discharge pipe 22 and the base 3 during work, reducing damage caused by external pulling. In other embodiments, the flexible sealing member 5 can also be made of silicone rubber, fluorine rubber, etc., which is not limited here.

[0051] As shown in Figure 1 , the end of the base 3 is connected to the outer periphery of the feed inlet 11 by welding. The welding ensures the tightness and stability of the connection, greatly enhances the sealing effect, effectively prevents dust from leaking from the connection during material conveying, and creates a clean production environment.

[0052] In this embodiment, the feed inlet 11 is constructed as a rectangular port, and the base 3 is constructed as a second square cylinder. The outer periphery of the port of the second square cylinder is connected to the outer periphery of the rectangular port by welding. The rectangular port and the second square cylinder have high compatibility, and the welding area is large during welding, greatly enhancing the firmness of the connection and greatly improving the sealing performance, effectively preventing dust from spilling during material conveying. At the same time, the rigid connection formed by welding can better resist the vibration and stress generated during the operation of the feeder 1. In other embodiments, the feed inlet 11 can also be constructed as a circular port or a polygonal port, which is not limited here.

[0053] In other embodiments, the end of the second square cylinder is provided with a turned-up edge in the circumferential direction, the feeding machine 1 is provided with an elastic sealing element around the circumferential direction of the rectangular port, the turned-up edge is pressed against the elastic sealing element, and the fastener is arranged through the turned-up edge and the elastic sealing element and is fixedly connected with the feeding machine 1, so that the end of the second square cylinder is sealingly connected with the four circumferences of the rectangular port. On the one hand, the turned-up edge increases the connection area, cooperates with the elastic sealing element, greatly improves the sealing effect, and effectively prevents dust leakage during material conveying. On the other hand, the elastic sealing element can buffer the vibration and displacement generated during the operation of the feeding machine 1, and reduce the wear of the components. In addition, this connection mode is convenient to install and disassemble, reduces the difficulty of maintenance, and reduces the downtime. The sealing connection mode of the end of the second square cylinder with the four circumferences of the rectangular port is not specifically limited here.

[0054] As shown in Figure 1 The first stopper 41 is welded to the outer wall of the discharge pipe 22, and the second stopper 42 is welded to the inner wall of the base 3. The firm connection ensures that the first stopper 41 and the second stopper 42 can still remain stable during the long-term operation and frequent vibration of the feeding machine 1, and ensures that the sealing performance is not affected.

[0055] In this embodiment, the first stopper 41 and the outer wall of the discharge pipe 22 are welded by using J422 welding rods, and the second stopper 42 and the inner wall of the base 3 are welded by using J422 welding rods. The type of welding rod is not specifically limited here.

[0056] In other embodiments, the first stopper 41 is fixed to the outer wall of the discharge pipe 22 by a fastener, and the second stopper 42 is fixed to the inner wall of the base 3 by a fastener. The fastener is convenient to install and disassemble, and when the first stopper 41 or the second stopper 42 is worn or aged, it can be quickly replaced.

[0057] In this embodiment, the first stopper 41 and the second stopper 42 are both made of hard material. The hard material has high strength and wear resistance, and can effectively resist dust erosion and vibration impact during long-term use, greatly prolonging the service life of the first stopper 41 and the second stopper 42, reducing the replacement frequency, and saving maintenance costs.

[0058] In this embodiment, the first stopper 41 and the second stopper 42 are flat steel. In other embodiments, the first stopper 41 and the second stopper 42 can also be made of stainless steel, titanium alloy, etc., which are not specifically limited here.
