Description
Technical Field
[0001] This utility model relates to a wet material crusher, belonging to the technical field of material processing equipment. Background Technology
[0002] Wet materials often have a high moisture content, which makes them prone to sticking together during the crushing process, clogging the screen of the crusher, and affecting crushing efficiency and quality. Existing crushing equipment has good performance in handling dry materials, but when dealing with wet materials, it is necessary to perform drying and other treatment processes before crushing, which increases production costs. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a wet material crusher that can effectively process high moisture materials, improve crushing efficiency and crushing quality, and reduce production costs.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a wet material crusher, comprising:
[0005] Support frame;
[0006] A crushing cylinder is mounted on the support frame and has a crushing chamber.
[0007] A stirring and conveying assembly, comprising a stirring shaft rotatably mounted in the grinding chamber, the stirring shaft having a spiral structure.
[0008] The crushing cylinder is provided with a first inlet and a first outlet, both of which are connected to the crushing chamber. A feeding funnel is provided on the first inlet.
[0009] The dehumidification assembly includes a heat source box, at least one first heat pipe and a second heat pipe. The heat source box is installed on the support frame. The first heat pipe is disposed in the feed funnel. A dehumidification chamber is provided between the crushing chamber and the outer surface of the crushing cylinder. One end of the second heat pipe is connected to the first heat pipe, and the second heat pipe is connected to the dehumidification chamber.
[0010] Furthermore, in order to control the crushing speed, the mixing and conveying assembly also includes a drive motor, a drive pulley, a driven pulley, and a timing belt. The drive motor is mounted on the support frame, the drive pulley is connected to the movable end of the drive motor, the driven pulley is connected to the mixing shaft, and the timing belt is adapted to connect the drive pulley and the driven pulley.
[0011] Furthermore, in order to improve the pulverization efficiency, the pitch of the spiral structure gradually decreases along the stirring shaft from the first inlet to the first outlet.
[0012] Furthermore, the inner wall of the grinding chamber is provided with multiple uniformly distributed grinding protrusions.
[0013] Furthermore, the crushing cylinder is equipped with a pressure gauge and a pressure relief solenoid valve, and the pressure relief solenoid valve is connected to the dehumidification chamber.
[0014] Furthermore, to facilitate the collection of the crushed material, a wet material crusher also includes a collection box assembly, which includes a collection box frame, a collection filter screen, and a pull-out collection trough. The collection box frame is installed on the support frame and located below the first outlet. The collection filter screen is installed above the collection box frame, and the pull-out collection trough is slidably installed below the collection box frame.
[0015] Furthermore, the pull-out collection slot is also equipped with a pull-out handle.
[0016] By adopting the above technical solution, this utility model has the following beneficial effects:
[0017] In this invention, wet granular material is conveyed from an external conveying device to the feed hopper. Part of the material enters the crushing chamber through the feed hopper, while some wet and sticky material accumulates on multiple first heat pipes. At this time, the hot air source box transfers hot air to the first heat pipes, and the surface of the first heat pipes preliminarily heats the wet material to evaporate its surface moisture, causing it to disperse and fall into the crushing chamber.
[0018] The drive motor drives the stirring shaft to rotate via a synchronous belt. The spiral structure pushes the material toward the first outlet with a decreasing pitch. During the process of pushing, the material is repeatedly squeezed and sheared by the spiral blades and crushing protrusions, gradually dispersing into individual small particles in a loose and non-sticky form.
[0019] During the crushing process, the hot air source box introduces hot air into the dehumidification chamber of the crushing cylinder through the first and second heat pipes. The heat indirectly heats the material in the crushing chamber through the chamber wall, further evaporating the internal moisture. When too much hot air in the dehumidifier chamber causes the pressure in the dehumidifier chamber to rise, the pressure relief solenoid valve automatically opens to discharge the air and maintain the safety of the dehumidifier chamber.
[0020] The crushed material is discharged from the first outlet and screened by a collection filter. Qualified particles fall into the pull-out collection trough, while coarse particles remain on the surface of the filter screen. Operators can collect the retained particles on the collection screen for secondary processing. The pull-out handle allows for quick and easy removal of the collection trough for operators to collect the finished product. Attached Figure Description

[0026] like Figure 1-4 As shown, a wet material crusher includes:
[0027] Support frame 1;
[0028] Crushing cylinder 2 is mounted on support frame 1 and has a crushing chamber 21.
[0029] A stirring and conveying assembly includes a stirring shaft 31, which is rotatably mounted in a grinding chamber 21, and a spiral structure 32 is provided on the stirring shaft 31.
[0030] The crushing cylinder 2 is provided with a first inlet 22 and a first outlet 23. Both the first inlet 22 and the first outlet 23 are connected to the crushing chamber 21. A feeding funnel 24 is provided on the first inlet 22.
[0031] The dehumidification assembly includes a heat source box 41, at least one first heat pipe 42 and a second heat pipe 43. The heat source box 41 is mounted on the support frame 1. The first heat pipe 42 is disposed in the feed funnel 24. A dehumidification chamber 25 is provided between the crushing chamber 21 and the outer surface of the crushing cylinder 2. One end of the second heat pipe 43 is connected to the first heat pipe 42, and the second heat pipe 43 is connected to the dehumidification chamber 25.
[0032] Specifically, such as Figure 1-4 As shown, the mixing and conveying assembly also includes a drive motor 51, a drive pulley 52, a driven pulley 53, and a synchronous belt 54. The drive motor 51 is mounted on the support frame 1. The drive pulley 52 is connected to the movable end of the drive motor 51. The driven pulley 53 is connected to the mixing shaft 31. The synchronous belt 54 is adapted to connect the drive pulley 52 and the driven pulley 53.
[0033] In this embodiment, the drive motor 51 drives the active pulley 52 to rotate clockwise, and the active pulley 53 drives the driven pulley 53 to rotate clockwise through the synchronous belt 54, so that the stirring shaft 31 and the spiral structure 32 are brought to the first outlet 23 of the material phase.
[0034] The crushing cylinder 2 is provided with bearing seats at both ends, and the stirring shaft 31 is mounted on the bearing seats;
[0035] The crushing cylinder 2 is also provided with a steam outlet, which is connected to the crushing chamber 21. Part of the water vapor generated by the material in the crushing chamber 21 is released through the steam outlet, and part of it is released from the first outlet 23.
[0036] Specifically, such as Figure 4 As shown, the pitch of the spiral structure 32 gradually decreases along the stirring shaft 31 from the first inlet 22 to the first outlet 23.
[0037] Specifically, such as Figure 4 As shown, the inner wall of the crushing chamber 21 is provided with a plurality of uniformly distributed crushing protrusions 26.
[0038] In this embodiment, the interaction between the spiral structure 32 and the crushing protrusions 26 can make the material more dispersed.
[0039] Specifically, such as Figure 1-4 As shown, the crushing cylinder 2 is equipped with a pressure gauge 61 and a pressure relief solenoid valve 62, which is connected to the dehumidification chamber 25.
[0040] Specifically, such as Figure 1-4 As shown, a wet material crusher also includes a collection box assembly, which includes a collection box frame 71, a collection filter 72, and a pull-out collection trough 73. The collection box frame 71 is mounted on the support frame 1 and located below the first outlet 23. The collection filter 72 is mounted above the collection box frame 71, and the pull-out collection trough 73 is slidably mounted below the collection box frame 71.
[0041] Specifically, such as Figure 1-4 As shown, the pull-out collection slot 73 is also equipped with a pull-out handle 731.
[0042] In this embodiment, the wet granular material is conveyed from the external conveying device to the feed hopper. Part of the material enters the crushing chamber 21 through the feed hopper 24, and part of the wet and sticky material accumulates on multiple first heat pipes 42. At this time, the hot air source box 41 transmits hot air to the first heat pipes 42. The surface of the first heat pipes 42 preliminarily heats the wet material to evaporate its surface moisture, causing it to disperse and fall into the crushing chamber 21.
[0043] The drive motor 51 drives the stirring shaft 31 to rotate via the synchronous belt 54. The spiral structure 32 pushes the material toward the first outlet 23 with decreasing pitch. During the process of pushing, the material is repeatedly squeezed and sheared by the spiral blades and crushing protrusions 26, and gradually disperses into individual small particles in a loose and non-sticky form.
[0044] During the crushing process, the hot air source box 41 introduces hot air into the dehumidification chamber 25 of the crushing cylinder 2 through the first heat pipe 42 and the second heat pipe 43. The heat indirectly heats the material in the crushing chamber 21 through the chamber wall, further evaporating the internal moisture. When too much hot air in the dehumidifier chamber causes the pressure in the dehumidifier chamber 25 to rise, the pressure relief solenoid valve 62 automatically opens to discharge the air and maintain the safety of the dehumidifier chamber.
[0045] The crushed material is discharged from the first outlet 23 and screened by the collection filter 72. Qualified particles fall into the pull-out collection trough 73, while coarse particles remain on the surface of the filter screen. Operators can collect the retained particles on the collection filter 72 for secondary processing. The pull-out handle 731 facilitates quick pulling out of the pull-out collection trough 73 for operators to collect the finished product.
