Description

Technical Field

[0001] The invention relates to the technical field of mullite brick production, in particular to a mullite brick production casting device. Background Art

[0002] Mullite bricks are high-alumina refractory materials with mullite as the main crystal phase. The general alumina content is between 65% and 75%. In addition to mullite, the low-alumina mineral components contain a small amount of glass phase and quartz, while the high-alumina mineral components contain a small amount of corundum. Lightweight mullite bricks are also used as thermal insulation layers for industrial kilns in metallurgy, petrochemicals, building materials, ceramics and other industries due to their good thermal insulation properties, such as heating furnaces, soaking furnaces, heat treatment furnaces, tunnel kilns, roller kilns, shuttle kilns, etc.

[0003] After searching, the Chinese patent with publication number CN118003455A discloses an aluminum alloy casting mold for improving casting defects, a mullite brick production casting device, including a casting platform, a mixing box and a molding box, the molding box is fixedly installed on the surface of the casting platform, a mixing and stirring mechanism is arranged inside the mixing box, an air pump box is fixedly installed on the back of the mixing box, a pressurized degassing mechanism is arranged inside the air pump box, a molding mechanism is arranged inside the molding box, and an inner wall cleaning mechanism is arranged on the back of the push plate. The mullite brick production casting device, by adopting the setting of the pressurized degassing mechanism, achieves the effect of rapid bubble removal and improves production efficiency. In addition, the material can be preliminarily compacted to facilitate subsequent molding. By adopting the setting of the through-hole connector, the molding box and the molding mechanism, the molding is more stable, so that the casting molding quality is improved, and the molding efficiency is further improved. By adopting the setting of the inner wall cleaning mechanism, some residual materials adhering to the inner wall of the molding box are removed, the adhesion effect after molding is reduced, and the molding quality is improved. However, when the technical solution is actually used, there are still the following shortcomings:

[0004] In the production process of mullite bricks, when high-alumina mullite brick raw materials are added to the forming mold, in order to ensure that the raw materials can be tightly combined to form bricks with a certain strength and density, it is usually necessary to use the cooperation of the cylinder and the pressing plate to apply sufficient pressure. However, since the mullite brick raw materials themselves have a certain viscosity, they are easy to adhere to the surface of the pressing plate. When the pressing plate goes deep into the mold to compact the raw materials, this adhesion phenomenon is particularly obvious. Over a long period of time, the raw materials adhered to the pressing plate will gradually accumulate and become difficult to remove, which will not only affect the flatness and dimensional accuracy of the subsequent brick molding, but may also cause damage to the mold and the pressing plate itself. At the same time, this adhesion phenomenon brings great inconvenience to the cleaning work during the production process.

[0005] Therefore, the present application provides a mullite brick production casting device to meet the cleaning requirements of the forming press plate. Summary of the invention

[0063] Beneficial effects of the present invention:

[0064] 1. The mullite brick production and casting device is provided with a control mechanism and a knocking assembly. When the pressing plate moves downward, the transmission gear drives the cam to rotate, and in turn drives the rotating rods and knocking heads at different positions to reverse and knock the mold, which is conducive to making the raw materials in the mold deposit more firmly, and at the same time shakes off the raw materials on the inner wall of the mold, which is convenient for subsequent extrusion molding, thereby improving the distribution uniformity and compactness of the raw materials in the mold.

When the pressure plate moves upward, the transmission gear 2 drives the paddle to rotate at high speed to generate airflow, and the gas flow direction is controlled by a one-way valve. Finally, the raw materials on the edge of the top surface of the mold are blown off through the nozzle, which is beneficial to prevent the raw materials from falling onto the molded bricks and keep the molded bricks clean, thereby achieving effective cleaning of the raw materials on the top surface of the mold.

[0066] 3. The mullite brick production and pouring device is provided with a pressing plate and a cleaning component. During the resetting process of the pressing plate, the transmission gear 3 drives the connecting rod to rotate, and the coil spring accumulates force. When the pressing plate is completely reset, the coil spring releases energy, drives the connecting rod to reverse, drives the reciprocating screw to rotate, and then drives the slide plate to slide back and forth along the guide rod, and the cleaning scraper cleans the bottom surface of the pressing plate, which is conducive to automatically cleaning the bottom surface of the pressing plate after each use, avoiding residues from affecting the next use, thereby realizing automatic cleaning of the bottom surface of the pressing plate and collection of materials.

[0078] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0080] like Figures 1 to 8 As shown, a mullite brick production and pouring device includes a conveying frame 1; a storage barrel 2, which is arranged at an upper position of the conveying frame 1 through a support frame; a fixing frame 3, which is fixedly installed on the top surface of the conveying frame 1; a cylinder 4, which is fixedly installed on the top surface of the fixing frame 3, and the telescopic end of the cylinder 4 passes through the top surface of the fixing frame 3; a pressing plate 5, which is fixedly installed on the telescopic end of the cylinder 4; a support plate 6, which is fixedly installed on the inner side wall of the bottom of one side of the fixing frame 3; a knocking component, which is arranged on the end of the support plate 6 away from the fixing frame 3; a sealing shell 8, which is fixedly installed on the top surface of the support plate 6 through a vertical rod; a blowing component, which is arranged on the sealing shell 8; a control mechanism, which is arranged on the inner side wall of the fixing frame 3; a connecting frame 11, which is fixedly installed on the inner side wall of the fixing frame 3; a cleaning component, which is arranged on the connecting frame 11;

[0081] When in use, a mold for forming mullite bricks is provided on the conveying frame 1. When the conveying frame 1 is opened, the mold can be driven to move. When the mold moves to the bottom of the storage barrel 2, the raw materials in the storage barrel 2 can be added to the mold. Then, the conveying frame 1 is continued to be opened to move the mold to the fixed frame 3 and is located directly below the pressing plate 5. At this time, the cylinder 4 is opened to drive the pressing plate 5 to move downward so that the pressing plate 5 can enter the mold to extrude and form the raw materials, ensuring that the raw materials in the mold can be formed into mullite brick blanks. In the process of the pressing plate 5 moving downward, the knocking component can be driven by the control mechanism to knock on the outer wall of the mold, so that the raw materials are deposited more firmly in the mold, and the raw materials attached to the inner wall of the mold can be shaken off for extrusion molding. In the process of the pressing plate 5 moving upward, the blowing component can be driven by the control mechanism to operate so that the gas blows off the raw materials at the edge of the top surface of the mold, making the mold tidier. After the pressing plate 5 is reset, the bottom surface of the pressing plate 5 can be cleaned by the cleaning component, so as to scrape off the material attached to the bottom surface of the pressing plate 5 to avoid adhesion. The working principle and connection method of the conveying frame 1 and the storage barrel 2 are existing mature technologies and will not be described in detail here.

[0082] like Figure 2 , Figure 3 As shown, the knocking assembly includes: a plurality of easing grooves 71, which are distributed in a linear array and are opened at one end of the support plate 6 away from the fixing frame 3; a plurality of rotating rods 72, which are respectively rotatably mounted on the inner side walls of the plurality of easing grooves 71 through connecting shafts and torsion springs; a plurality of knocking heads 73, which are respectively fixedly mounted on the bottom ends of the plurality of rotating rods 72, and the outer wall of the knocking head 73 is provided with a rubber pad; a bracket 74, which is fixedly mounted on the top surface of the support plate 6; a rotating shaft 75, which is rotatably mounted on the top of the bracket 74; a plurality of cams 76, which are distributed in a linear array and fixedly sleeved on the outer wall of the rotating shaft 75, and the position of the cam 76 corresponds to the position of the rotating rod 72, and the angles of the plurality of cams 76 are all different; a transmission gear 77, which is fixedly mounted on the end of the rotating shaft 75;

[0083] In the process of the pressing plate 5 moving downward to the middle of the mold, the transmission gear 77 can be driven to rotate by the control mechanism first. In the initial position, the rotating rod 72 is in an inclined state under the action of the torsion spring, and the outer wall of the striking head 73 can fit the outer wall of the mold. The transmission gear 77 drives the rotating shaft 75 to rotate, and the cam 76 can be driven to rotate synchronously. The initial angles of several cams 76 are different. Therefore, the rotating rods 72 and the striking heads 73 at different positions can be driven to reverse in turn during the rotation process, and when the cam 76 is separated from the rotating rod 72, the rotating rod 72 and the striking head 73 can be rotated under the action of the torsion spring to strike the mold, so that the raw materials in the mold are deposited more firmly, and the raw materials on the inner wall of the mold can be shaken off for extrusion molding.

[0084] like Figure 2 , Figure 4 As shown, the blowing assembly includes: a transmission shaft 91, which is rotatably mounted on the inner wall of the sealing shell 8, and one end of the transmission shaft 91 passes through the sealing shell 8; a plurality of paddles 92, which are arranged in a circular array and fixedly mounted on the outer wall of the transmission shaft 91; a transmission gear 93, which is fixedly mounted on one end of the transmission shaft 91 located outside the sealing shell 8; a plurality of air inlet pipes 94, which are arranged in a linear array on the outer wall of the sealing shell 8, and the air inlet pipes 94 are connected to the sealing shell 8; a plurality of air outlet pipes 95, which are arranged in a linear array on the outer wall of the sealing shell 8, and the air outlet pipes 95 are connected to the sealing shell 8, and the inner walls of the air inlet pipes 94 and the air outlet pipes 95 are installed with one-way valves with opposite flow directions; a plurality of nozzles 96, which are respectively arranged at one end of the plurality of air outlet pipes 95 away from the sealing shell 8, and the nozzles 96 are arranged opposite to the forming mold;

[0085] During the upward movement of the pressing plate 5, the transmission gear 2 93 can be driven to rotate through the control mechanism. During the rotation of the transmission gear 2 93, the paddle 92 can be driven to rotate at high speed through the transmission shaft 91. During the rotation of the paddle 92, since the inlet pipe 94 and the outlet pipe 95 are equipped with one-way valves with opposite flow directions, the gas can enter the sealing shell 8 through the inlet pipe 94, and can be discharged through the outlet pipe 95, and finally sprayed out through the nozzle 96, so that the raw materials at the edge of the top surface of the mold can be blown off. The whole process occurs when the pressing plate 5 is located in the mold, which prevents the raw materials from being blown onto the molded bricks.

[0086] like Figure 2 , Figure 5 As shown, the control mechanism includes: a guide sleeve 101, which is fixedly mounted on the top surface of the pressure plate 5 through a fixed plate; a slide bar 102, which is slidably mounted on the inner wall of the guide sleeve 101; a double-sided rack 103, which is fixedly mounted on one end of the slide bar 102 located outside the guide sleeve 101; a magnetic sheet 104, which is fixedly mounted on the top of the double-sided rack 103; two support rods 105, which are fixedly mounted on the inner wall of the fixed frame 3, and the position of the bottom support rod 105 of the two support rods 105 is opposite to the transmission gear 1 77; two magnetic sheets 2 106, which are respectively fixedly mounted on one end of the two support rods 105 away from the fixed frame 3, the magnetic sheet 104 is opposite to the magnetic sheet 2 106, and the upper magnetic sheet 106 of the two magnetic sheets 106 has the same magnetic pole as the magnetic sheet 104, and the lower magnetic sheet 106 of the two magnetic sheets 106 has an opposite magnetic pole to the magnetic sheet 104;

[0087] When the cylinder 4 drives the pressure plate 5 to move downward from the initial position, since the magnetic piece 104 at the top of the double-sided rack 103 at the initial position can be opposite to the magnetic piece 2 106 at the end of the top support rod 105, and the relative magnetic poles of the two are the same, the slide rod 102 can slide inward along the guide sleeve 101 under the action of the repulsive magnetic force, so that the double-sided rack 103 is located away from the magnetic piece 2 106. At this time, when the pressure plate 5 moves downward, it can drive the transmission gear 1 77 to rotate through the double-sided rack 103. When the pressure plate 5 moves to the lowest position, the magnetic piece 104 can be opposite to the bottom support rod 1 The magnetic sheets 106 at the ends of 05 are opposite to each other, and their relative poles are opposite. Therefore, under the action of the attractive magnetic force, the slide bar 102 can slide outward along the guide sleeve 101, so that the double-sided rack 103 can engage with the transmission gear 93. Therefore, the transmission gear 93 can be driven to rotate during the upward movement of the pressure plate 5. There is a certain damping effect between the slide bar 102 and the guide sleeve 101, so the stability of the double-sided rack 103 during movement can be ensured. The technology used for the damping effect between the slide bar 102 and the guide sleeve 101 is an existing mature technology, which will not be elaborated here.

[0088] like Figures 6 to 8 As shown, the cleaning assembly includes: a guide rod 121, fixedly mounted on the inner wall of the fixed frame 3; a reciprocating screw 122, rotatably mounted on the inner wall of the fixed frame 3 and the guide rod 121 at a symmetrical position; a slide plate 123, arranged on the guide rod 121 and the reciprocating screw 122, and the two ends of the slide plate 123 are respectively slidably connected to the guide rod 121 and screwed to the reciprocating screw 122; a cleaning scraper 124, fixedly mounted on the top surface of the slide plate 123; a collection box 125, fixedly mounted on the bottom surface of the slide plate 123, and the width of the collection box 125 is at least greater than the width of the slide plate 123; a connecting rod 126, rotatably mounted on the end of the connecting frame 11, and The connecting rod 126 is coaxially arranged with the reciprocating screw 122; the transmission gear three 127 is sleeved on the end of the connecting rod 126 away from the connecting frame 11 through a one-way bearing; a plurality of fixed teeth 128 are distributed in a linear array and fixedly installed on the side of the double-sided rack 103, and the transmission gear three 127 is meshed with the fixed teeth 128, and the width of the transmission gear three 127 is at least twice the width of the fixed teeth 128; the coil spring 129 is sleeved on the connecting rod 126, and the two ends of the coil spring 129 are fixedly connected to the connecting rod 126 and the connecting frame 11 respectively; the connecting mechanism is arranged between the opposite ends of the reciprocating screw 122 and the connecting rod 126;

[0089] During the process of the pressure plate 5 being reset with the cylinder 4, when the fixed teeth 128 on the side of the double-sided rack 103 mesh with the transmission gear three 127, this direction is the locking direction of the one-way bearing, thereby driving the transmission gear three 127 and the connecting rod 126 to rotate, while the reciprocating screw 122 cannot rotate in this direction under the action of the connecting mechanism. During the rotation of the transmission gear three 127 and the connecting rod 126, the coil spring 129 can be driven, so that the coil spring 129 rotates and accumulates force. When the pressure plate 5 is completely reset, the transmission gear three 127 is separated from the fixed teeth 128. Under the action of the coil spring 129, the connecting rod 126 can be reversed, and the reciprocating screw 122 can be driven to rotate through the connecting mechanism. During the rotation of the reciprocating screw 122 Since the two ends of the slide plate 123 are respectively screwed with the reciprocating screw 122 and slidably connected with the guide rod 121, the reciprocating screw 122 can drive the slide plate 123 to slide back and forth along the guide rod 121 when it rotates, so that the bottom surface of the pressure plate 5 can be cleaned by the cleaning scraper 124 on the top surface of the slide plate 123, and the cleaned material can fall into the collection box 125 for collection, and when the pressure plate 5 is used again to move downward, the fixed teeth 128 are engaged with the transmission gear three 127, because this direction is the free state direction of the one-way bearing, the fixed teeth 128 can drive the transmission gear three 127 to rotate but cannot drive the connecting rod 126 to rotate. The positions of the slide plate 123 and the cleaning scraper 124 remain unchanged, ensuring that the pressure plate 5 can move downward normally for use.

[0090] like Figure 8 As shown, the connection mechanism includes: a transmission plate 1210, which is slidably mounted on the end of the reciprocating screw 122 through a sliding groove and a slider; a spring 1211, which is mounted on the reciprocating screw 122, and the two ends of the spring 1211 are respectively fixedly connected to the reciprocating screw 122 and the transmission plate 1210; a driving plate 1212, which is fixedly mounted on the end of the connecting rod 126; a plurality of one-way teeth 1213, which are distributed in an annular array and fixedly mounted on the side of the driving plate 1212; a plurality of one-way tooth grooves 1214, which are distributed in an annular array and opened on the side of the transmission plate 1210;

[0091] In the process of the fixed tooth 128 driving the transmission gear three 127 to rotate, since the one-way tooth 1213 in this direction is opposite to the arc surface of the one-way tooth groove 1214, the driving disk 1212 can only push the transmission disk 1210 when it rotates, and cannot drive the transmission disk 1210 to rotate. When the transmission gear three 127 and the connecting rod 126 are reversed, the one-way tooth 1213 is opposite to the vertical surface of the one-way tooth groove 1214, so the driving disk 1212 can drive the transmission disk 1210 to rotate, thereby driving the reciprocating screw 122.

[0092] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples.
