Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to a sludge solidification and molding device. Background Technology

[0002] With the rapid advancement of urbanization and the continuous expansion of industrial production, sewage sludge after wastewater treatment has become an extremely complex and difficult-to-handle heterogeneous substance. Sludge is mainly composed of organic fragments, bacterial cells, inorganic particles, and colloids, and is characterized by high water content (up to 99% or more), high organic matter content, easy putrefaction and odor, fine particles, low specific gravity, and a colloidal liquid state. Current technologies solidify sludge before further processing, mixing it with specific solidifying agents and using molding equipment to process it into solid materials with a certain shape and strength. This effectively reduces the volume of sludge and improves its stability. However, existing equipment cannot achieve fully automated feeding, molding, and heating, and the precision of each step in the processing must be ensured. Utility Model Content

[0003] The purpose of this invention is to provide a sludge solidification molding device with a high degree of automation and improved molding efficiency.

[0004] A sludge solidification molding device includes a mounting frame, in which a plurality of lifting and conveying mechanisms are installed. The lifting and conveying mechanisms are used to convey a solidification molding mold, and the solidification molding mold is provided with a plurality of molding grooves.

[0005] Above the lifting and conveying mechanism, there is a feeding mechanism, a forming mechanism, and a heating mechanism. The feeding mechanism, forming mechanism, and heating mechanism are mounted on the mounting frame. The inner side of the feeding mechanism, forming mechanism, and heating mechanism is provided with a positioning support mechanism. The positioning support mechanism is mounted on the mounting frame and is used to position and support the solidified molding mold.

[0006] In the above scheme, the lifting and conveying mechanism is used to transport the solidification molding mold in the horizontal and vertical directions and realize the return of the solidification molding mold. The molding groove on the solidification molding mold is used to solidify and shape the sludge. The lifting and conveying mechanism first transports the solidification molding mold to the position of the feeding mechanism. After the positioning and support mechanism positions and supports the solidification molding mold, the feeding mechanism sends the sludge to be formed to the solidification molding mold. Then, the lifting and conveying mechanism transports the solidification molding mold to the position of the molding mechanism, where the molding mechanism compacts and shapes the sludge. During this process, the positioning and support mechanism also positions and supports the solidification molding mold. Afterward, the lifting and conveying mechanism transports the solidification molding mold to the position of the heating mechanism to accelerate the evaporation and solidification of the sludge. This device can also realize the automatic return of the solidification molding mold.

[0007] Furthermore, the lifting and conveying mechanism includes a lifting component and a conveying component. The conveying component includes a first driving member, a transmission rod, and a conveying bracket. A synchronous pulley is installed inside the conveying bracket, and a synchronous belt is wound around the synchronous pulley. The transmission rod is connected to the synchronous pulley, and the first driving member is connected to the transmission rod.

[0008] In the above scheme, the first driving component is installed on one side wall of the conveying bracket. The first driving component is used to drive the transmission rod to rotate, and the transmission rod drives the synchronous wheel to rotate, thereby driving the synchronous belt to convey the curing mold in the horizontal direction. The lifting component can drive the conveying component to move in the vertical direction, thereby driving the curing mold to move in the vertical direction.

[0009] Furthermore, the lifting assembly includes a mounting plate, a linear guide rail, a sliding block, a second driving component, a transmission screw, and a screw nut. The mounting plate is vertically mounted on the mounting frame. The linear guide rail and the transmission screw are mounted on the mounting plate. The sliding block is slidably connected to the linear guide rail. The screw nut is rotatably connected to the transmission screw. The conveying assembly is connected to the screw nut and the sliding block. The second driving component is used to drive the transmission screw to rotate.

[0010] In the above scheme, the second driving component drives the transmission screw to rotate, which in turn drives the screw nut to move along the transmission screw, thereby enabling the conveying component connected to the screw nut to move back and forth in the vertical direction. The cooperation between the sliding block and the linear guide rail can ensure the smooth lifting and lowering of the conveying component.

[0011] Furthermore, the feeding mechanism includes a hopper, a feed tube, and a rotating assembly. A plurality of the feed tubes are connected to the hopper, a plurality of the feed tubes are connected to the feed tubes, and the rotating assembly passes through the hopper.

[0012] In the above scheme, the sludge to be formed is poured into the silo, the sludge is pushed to the hopper by the rotating component, and finally sent to the forming tank through the feeding pipe.

[0013] Furthermore, the rotating assembly includes a support plate, a third driving member, and a spiral rotating shaft. The support plate is installed on the top of the hopper, and a plurality of the third driving members are installed on the support plate. The output end of the third driving member passes through the support plate and is connected to the spiral rotating shaft.

[0014] In the above scheme, the support plate is used to support the third driving component, which can drive the spiral shaft to rotate, thereby continuously stirring and pushing the sludge, so that the sludge is pushed to the hopper and the feeding pipe.

[0015] Furthermore, the forming mechanism includes a support frame, a fourth driving component, a connecting plate, and a forming pressure plate. The fourth driving component is mounted on the support frame, and its output end passes through the support frame and is connected to the connecting plate. The connecting plate is connected to the forming pressure plate via guide posts and guide sleeves. The forming pressure plate is provided with compaction blocks corresponding to the forming groove.

[0016] In the above scheme, the support frame is used to support the molding mechanism. During molding, the fourth driving component drives the connecting plate to press down, thereby driving the molding plate to press down, so that the compaction block can squeeze the sludge into shape. The compaction block corresponds one-to-one with the molding groove, thereby ensuring the molding efficiency. The guide column and guide sleeve can play a certain buffering role.

[0017] Furthermore, the heating mechanism includes a mounting base, a lamp mounting plate, and heating lamps. The mounting base is mounted on the mounting frame, the lamp mounting plate is installed inside the mounting base and located above the lifting and conveying mechanism, and a plurality of heating lamps are mounted on the lamp mounting plate.

[0018] In the above scheme, the heating lamp tube, as a direct heating element, is installed on the lamp tube mounting plate, which can heat the solidification mold below in a concentrated and uniform manner, thereby improving heating efficiency and effect. This design ensures that the sludge can be heated quickly and evenly during the solidification process, thereby accelerating the evaporation of water and the solidification speed of the sludge.

[0019] Furthermore, the positioning support mechanism includes a first pushing component, a second pushing component, a positioning column, and a support block. The output end of the first pushing component is connected to the support block, and the output end of the second pushing component is connected to the positioning column. The curing mold has an overlapping block at one end near the support block, and a protruding structure at one end near the positioning column. The protruding structure has a positioning hole.

[0020] In the above scheme, the first pushing component can drive the support block to abut against the overlapping block, and the second pushing component can push the positioning column into the positioning hole of the protruding structure. The position of the feeding mechanism and the forming mechanism can ensure the accuracy of the position of the solidified forming mold. The position of the heating mechanism can support the solidified forming mold while positioning, so that the lifting and conveying mechanism can move freely up and down to realize the return of the solidified forming mold.

[0021] This utility model discloses a sludge solidification molding device with high automation and improved molding efficiency. A lifting and conveying mechanism is used to transport the solidification molding mold horizontally and vertically and to achieve mold return. The molding groove on the solidification molding mold is used to solidify and mold the sludge. The lifting and conveying mechanism first transports the solidification molding mold to the feeding mechanism. After the positioning and support mechanism positions and supports the solidification molding mold, the feeding mechanism sends the sludge to be molded to the solidification molding mold. Then, the lifting and conveying mechanism transports the solidification molding mold to the molding mechanism, where the molding mechanism compacts and molds the sludge. During this process, the positioning and support mechanism also positions and supports the solidification molding mold. Afterward, the lifting and conveying mechanism transports the solidification molding mold to the heating mechanism to accelerate the evaporation and solidification of the sludge. This device can also achieve automatic return of the solidification molding mold. Attached Figure Description

The forming groove 31 on the solidification mold 3 is used to solidify and form the sludge. The lifting and conveying mechanism 2 first transports the solidification mold 3 to the position of the feeding mechanism 4. After the positioning and support mechanism 7 positions and supports the solidification mold 3, the feeding mechanism 4 sends the sludge to be formed to the solidification mold 3. Then, the lifting and conveying mechanism 2 transports the solidification mold 3 to the position of the forming mechanism 5, where the forming mechanism 5 compacts and forms the sludge. During this process, the positioning and support mechanism 7 also positions and supports the solidification mold 3, ensuring the accurate position and stable support of the solidification mold 3 throughout the solidification process. After that, the lifting and conveying mechanism 2 transports the solidification mold 3 to the position of the heating mechanism 6 to accelerate the evaporation and solidification of the sludge.

[0031] The device can also realize the automatic return of the solidification mold 3. Specifically, during the heating process of sludge in the first solidification mold 3, the solidification of sludge in the second solidification mold 3 can be carried out simultaneously. When the first solidification mold 3 is unloaded, the second solidification mold 3 is supported by the positioning support mechanism 7 at the position of the heating mechanism 6.

Here, the screw nut is a conventional technology and will not be described or represented in detail. This allows the conveying assembly 22 connected to the screw nut to move back and forth in the vertical direction.
