Description

Technical Field

[0001] This utility model relates to the technical field of ovens, and in particular to a hot air circulating oven for continuous firing and molding of ceramic parts. Background Technology

[0002] Ceramics not only hold an important place in my country's long history of art, but ceramic products are also ubiquitous in our daily lives. Currently, a drying step is required in ceramic processing, necessitating the use of specialized drying ovens for efficient drying. Existing technology publication number CN219264744U discloses a hot air circulating drying oven, including a drying chamber with horizontally spaced hot air chambers and a drying chamber. A partition is provided between the hot air chambers and the drying chamber, and the partition has a plurality of air holes evenly distributed on it. A hot air blower connected to the hot air chambers is mounted on the drying chamber, and a plurality of trays are installed along its height in the drying chamber. The partition also includes a baffle that adheres to the surface of the partition to block some of the air holes, and a control structure for controlling the baffle's back-and-forth movement along the height of the partition. However, during heating and drying, hot and humid gas accumulates inside the oven, potentially affecting the drying effect and preventing continuous drying operations. The ceramics can only be removed after the drying chamber temperature has decreased, impacting processing efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a hot air circulating oven for continuous firing and forming of ceramic parts, which reduces the amount of hot and humid gas in the drying chamber to reduce the impact on the drying effect, and can continuously dry ceramic parts and improve processing efficiency.

[0004] This utility model discloses a hot air circulating oven for continuous firing and molding of ceramic parts, comprising a base, a box body, a drying component, a moving component, and a condensing component. The box body is installed on top of the base, with a drying chamber in the middle. The drying component is installed inside the drying chamber, and a condensing component is connected to the drying component. Cooling chambers are located at the left and right ends of the box body, with cavities formed in the inner walls of the cooling chambers on both sides. Heat-absorbing cotton is placed inside the cavities. The moving component is installed on top of the base, and a placement component is installed on top of the moving component. The drying component heats the interior of the drying chamber in the middle of the box body. Ceramic parts are placed on the placement component, and the moving component moves the ceramic parts into the box body, allowing them to gradually heat up. After the ceramic parts reach the drying chamber, they are dried. Simultaneously, the condensing component prevents liquid from accumulating in the box body and affecting the normal operation of the oven. After the ceramic parts are dried, they continue to move into the cooling chamber to cool down. Meanwhile, undried ceramic parts enter the drying chamber for continuous drying, improving processing efficiency.

[0005] Preferably, the drying assembly includes a blower, an air duct, multiple heating coils, a drying chamber, and an air inlet pipe. Heating chambers are formed in the inner walls at both ends of the drying chamber. Multiple heating coils are fixedly installed inside the heating chambers. The blower is installed on the rear side wall of the chamber. Multiple channels are formed inside the base, communicating with the bottom of the two heating chambers. The output end of the blower is connected to the channels via the air duct. Multiple through holes communicating with the drying chamber are formed inside the heating chamber. The drying chamber is installed on the rear side wall of the chamber. The input end of the blower is connected to the output end of the drying chamber. An air inlet pipe is connected to the input end of the drying chamber. The interior of the drying chamber is filled with desiccant. After the ceramic part is moved to the drying chamber position, the blower is activated to extract air. The gas enters the drying chamber through the air inlet pipe, is dried, and then enters the channels through the air duct, and finally enters the heating chamber. The heating coils are activated to heat the gas. The hot gas enters the drying chamber through the through holes to dry the ceramic part.

[0006] Preferably, the condensing component includes multiple connecting pipes, a condenser pipe, and a drain pipe. A condensing chamber is provided at the top of the chamber corresponding to the drying chamber. Multiple connecting pipes are connected inside the condensing chamber. The input end of the connecting pipe is connected to the top of the drying chamber, and the output end of the connecting pipe is higher than the bottom of the condensing chamber. The condenser pipe is installed in the condensing chamber. The output end of the rear wall of the condensing chamber is connected to the air inlet pipe, and a drain pipe is connected to the bottom of the front end of the condensing chamber. The hot and humid gas in the drying chamber enters the condensing chamber through the connecting pipe. The hot and humid gas liquefies upon contact with the condenser pipe. The liquefied water is discharged from the condensing chamber through the drain pipe, and the gas is reintroduced into the air inlet pipe for circulation, thereby reducing the amount of hot and humid gas in the drying chamber and minimizing its impact on the drying effect.

[0007] Preferably, the moving assembly includes a threaded shaft, a forward and reverse motor, multiple moving seats, and a moving base. A moving groove is formed at the center of the top of the base. The threaded shaft is rotatably mounted within the moving groove. The left input end of the threaded shaft passes through the left side wall of the base and connects to the output end of the forward and reverse motor. Multiple moving seats are slidably mounted within the moving groove, and the moving seats are screwed onto the outer wall of the threaded shaft. The moving base is fixedly connected to the top of each moving seat, and the front and rear sides of the moving base are in sealed sliding contact with the inner wall of the chamber. Starting the forward and reverse motor drives the threaded shaft to rotate, which in turn drives the moving seats to move within the moving groove, thereby moving the moving base within the chamber. This facilitates the gradual movement of multiple sets of ceramic parts, achieving continuous drying and improving work efficiency.

[0008] Preferably, the placement assembly includes multiple sealing side plates, multiple sets of placement baffles, multiple grid plates, and multiple sealing strips. Multiple sealing side plates are evenly spaced on the top of the movable base. Multiple sets of placement baffles are spaced apart on the sidewalls between adjacent sealing side plates. The grid plates are placed on top of the placement baffles between two sealing side plates, and sealing strips are installed on the outer walls of the sealing side plates. Ceramic parts are sequentially placed onto the grid plates. After one layer is filled, the next layer of grid plates is placed onto the placement baffles to continue placement. After placement, the movable base moves, moving the ceramic parts into the chamber. The ceramic parts first enter the cooling chamber, then the drying chamber. The sealing side plates seal the drying chamber, and the sealing strips ensure the sealing between the sealing side plates and the inner wall of the chamber, reducing heat loss. After the rightmost group of ceramic parts is dried, it moves to the right into the right-side cooling chamber, while the next group of ceramic parts enters the drying chamber, enabling continuous drying and improving work efficiency.

[0009] Preferably, it also includes two sets of support rollers. The top of the base has symmetrically opened walking grooves about the front and back of the moving slide. Multiple support rollers are installed at the front and back ends of the bottom of the moving base corresponding to the walking grooves. The support rollers are rolled in the walking grooves. When the moving base moves, it drives the support rollers to roll in the walking grooves to support the bottom of the moving base and ensure the stability of the moving base when it moves.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the drying component heats the interior of the drying chamber in the middle of the box, the ceramic parts are placed on the placement component, and the moving component moves the ceramic parts into the box, so that the ceramic parts are gradually heated in the box. After the ceramic parts are moved to the drying chamber, they are dried. At the same time, the condensation component can prevent liquid from accumulating in the box and affecting the normal operation of the oven. After the ceramic parts are dried, they continue to move into the cooling chamber to cool them down. Meanwhile, the undried ceramic parts enter the drying chamber for continuous drying, thus improving processing efficiency. Attached Figure Description

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0020] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the chamber 2 is installed on top of the base 1. The middle of the chamber 2 is a drying chamber, and the left and right ends of the chamber 2 are cooling chambers. The inner walls of the left and right cooling chambers of the chamber 2 have cavities, and heat-absorbing cotton 3 is placed inside the cavities. The inner walls of the front and rear ends of the drying chamber have heating chambers, and multiple heating coils 6 are fixedly installed inside the heating chambers. The blower 4 is installed on the rear wall of the chamber 2. The base 1 has multiple channels inside, which are connected to the bottom of the two heating chambers. The output end of the blower 4 is connected to the channels through an air supply pipe 5. The heating chamber has multiple through holes inside that communicate with the drying chamber. The drying chamber 7 is installed on the rear wall of the chamber 2. The input end of the blower 4 is connected to the output end of the drying chamber 7. The input end of the drying chamber 7 is connected to an air inlet pipe 8. The interior of the drying chamber 7 is filled with drying fluid. The base 1 has a movable slide groove at the top center. The threaded shaft 12 is rotatably installed in the movable slide groove. The left input end of the threaded shaft 12 passes through the left side wall of the base 1 and is connected to the output end of the forward and reverse motor 13. Multiple movable seats 14 are slidably installed in the movable slide groove, and the movable seats 14 are screwed onto the outer wall of the threaded shaft 12. The top of the movable seat 14 is fixedly connected to the movable base 15. The front and rear sides of the movable base 15 are in sealed sliding contact with the inner wall of the box 2. Multiple sealing side plates 17 are evenly spaced on the top of the movable base 15. Multiple sets of placement baffles 18 are spaced on the side wall between two adjacent sealing side plates 17. The grid plate 19 is placed on the top of the placement baffles 18 between two sealing side plates 17. Sealing strips 20 are installed on the outer wall of the sealing side plate 17.

[0021] The ceramic parts are placed sequentially on the grid plate 19. After one layer is filled, the next layer of grid plate 19 is placed on the placement baffle 18 and the process continues. After placement, the forward and reverse motor 13 is started to drive the threaded shaft 12 to rotate. The threaded shaft 12 drives the moving seat 14 to move in the moving slide, thereby driving the moving base 15 to move inside the chamber 2. This facilitates the gradual movement of multiple sets of ceramic parts, thus achieving continuous drying and improving work efficiency. The movement of the moving base 15 moves the ceramic parts into the chamber 2. The ceramic parts first enter the cooling chamber and then the drying chamber. The drying chamber can be sealed by the sealing side plate 17. After the ceramic parts are moved to the drying chamber, the blower 4 is started to draw in air. The gas enters the drying chamber 7 through the air inlet pipe 8, and after drying, it is input into the channel through the air supply pipe 5 and then enters the heating chamber. The heating coil 6 is started to heat the gas. The hot gas enters the drying chamber through the through hole to dry the ceramic parts. The sealing strip 20 can ensure the sealing of the sealing side plate 17 and the inner wall of the chamber 2, reducing heat loss. After the rightmost group of ceramic parts is dried, it moves to the right and enters the right cooling chamber. At the same time, the next group of ceramic parts enters the drying chamber, so that continuous drying can be carried out and the work efficiency is improved. Example 2

[0022] like Figure 2 , Figure 5 and Figure 7As shown, based on embodiment 1, a condensing chamber is provided at the top of the box 2 corresponding to the drying chamber. Multiple connecting pipes 9 are connected inside the condensing chamber. The input end of the connecting pipe 9 is connected to the top of the drying chamber, and the output end of the connecting pipe 9 is higher than the bottom of the condensing chamber. A condensing pipe 10 is installed in the condensing chamber. The output end of the rear wall of the condensing chamber is connected to the air inlet pipe 8. A drain pipe 11 is connected to the bottom of the front end of the condensing chamber. A walking groove is symmetrically provided on the top of the base 1 about the front and rear of the moving slide. Multiple supporting rollers 16 are installed at the front and rear ends of the bottom of the moving base 15 corresponding to the walking groove. The supporting rollers 16 are rolled in the walking groove.

[0023] The hot and humid gas in the drying chamber of the box 2 enters the condensation chamber through the connecting pipe 9. The hot and humid gas liquefies upon contact with the condenser pipe 10. The liquefied water is discharged from the condensation chamber through the drain pipe 11. The gas is then reintroduced into the air inlet pipe 8 for circulation, reducing the amount of hot and humid gas in the drying chamber to minimize its impact on the drying effect. When the movable base 15 moves, it drives the support rollers 16 to roll in the travel groove, supporting the bottom of the movable base 15 and ensuring the stability of the movable base 15 during movement.

[0024] like Figures 1 to 7 As shown, this utility model discloses a hot air circulating oven for continuous firing and molding of ceramic parts. During operation, ceramic parts are sequentially placed onto the grid plate 19. After one layer is filled, the next layer of grid plate 19 is placed onto the placement baffle 18 for further placement. After placement, the forward and reverse motor 13 is started, driving the threaded shaft 12 to rotate. The threaded shaft 12 drives the moving seat 14 to move in the moving slide, thereby moving the moving base 15 within the chamber 2. This causes multiple sets of ceramic parts to move gradually. The moving base 15 moves the ceramic parts into the chamber 2. During movement, the moving base 15 drives the supporting rollers 16 to roll in the travel groove, supporting the bottom of the moving base 15. The ceramic parts first enter the cooling chamber and then the drying chamber. The drying chamber is sealed by the sealing side plate 17. After closing and moving to the drying chamber position, the blower 4 is started to extract air. The gas enters the drying chamber 7 through the air inlet pipe 8, and after drying, it is input into the channel through the air supply pipe 5, and then enters the heating chamber. The heating coil 6 is started to heat the gas. The hot gas enters the drying chamber through the through hole to dry the ceramic parts. The hot and humid gas in the drying chamber of the chamber 2 enters the condensation chamber through the connecting pipe 9. The hot and humid gas liquefies upon contact with the condenser pipe 10. The liquefied water is discharged from the condensation chamber through the drain pipe 11. The gas is reintroduced into the air inlet pipe 8 for circulation, reducing the hot and humid gas in the drying chamber to reduce the impact on the drying effect. After the rightmost group of ceramic parts is dried, it moves to the right and enters the right cooling chamber. At the same time, the next group of ceramic parts enters the drying chamber, thus enabling continuous drying.

[0025] The blower 4, heating coil 6, drying box 7, condenser 10, and forward / reverse motor 13 of the hot air circulating oven for continuous firing of ceramic parts of this utility model are commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
