[0002] Dry anaerobic fermentation raw materials are mainly solid organic waste (total solid concentration ≥20%), which can undergo anaerobic fermentation with little or no water.
[0003] To improve fermentation efficiency, existing dry anaerobic fermentation raw materials are often pulverized to ensure that microorganisms can better contact and decompose organic matter. However, some moisture remains inside the raw materials during pulverization, which can easily accumulate in the processing device and cause blockage. To address these problems and shortcomings, a pretreatment device for dry anaerobic fermentation raw materials is urgently needed. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a dry anaerobic fermentation raw material pretreatment device to solve the problem that existing dry anaerobic fermentation raw materials are mostly crushed in order to improve their fermentation efficiency, so as to ensure that microorganisms can better contact and decompose organic matter. However, when the dry anaerobic fermentation raw materials are crushed, some moisture will be present inside, which will easily accumulate in the treatment device after crushing, causing the device to be blocked.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A dry anaerobic fermentation raw material pretreatment device includes: a shell, on which a crushing component, an anti-clogging component, and a drying component are provided; a feed pipe is fixedly connected to the top of the shell, and a sealing door is rotatably connected to the outer wall of the shell; the anti-clogging component includes a spring installed on the outer wall of the shell, a fixing plate is fixedly mounted on the end of the spring away from the shell, a partition is fixedly mounted on the outer wall of the shell, a motor is fixedly mounted on the outer wall of the partition, a rotating rod is fixedly mounted on the end of the output shaft of the motor, a cam is fixedly mounted on the outer wall of the rotating rod, a vertical plate is fixedly mounted on the side of the fixing plate near the shell, the vertical plate penetrates the shell, and a top plate is fixedly mounted on the side of the vertical plate away from the fixing plate.
[0007] Preferably, the crushing assembly includes a second motor mounted on the outer wall of the housing, a first rotating shaft fixedly mounted at the end of the output shaft of the second motor, a first crushing roller fixedly mounted on the outer wall of the first rotating shaft, a transmission belt meshing with the outer wall of the first rotating shaft, a second rotating shaft meshing with the outer wall of the transmission belt, and a second crushing roller fixedly mounted on the outer wall of the second rotating shaft.
[0008] Preferably, the drying assembly includes a groove formed in the inner wall of the housing, an electric heating wire is fixedly mounted on the inner wall of the groove, and a side plate is fixedly mounted on the inner wall of the groove.
[0009] Preferably, a round rod is rotatably connected to the inner wall of the feed tube, a baffle is fixedly mounted on the outer wall of the round rod, and a spring is fixedly mounted on the inner wall of the feed tube, with the side of the spring away from the feed tube being fixedly connected to the baffle.
[0010] Preferably, a folded cloth is fixedly fitted on the side of the top plate near the inner wall of the shell, and the side of the folded cloth away from the top plate is fixedly connected to the shell.
[0011] Preferably, a sleeve is fixedly fitted to the outer wall of the housing, a damping block is slidably connected to the inner wall of the sleeve, a moving rod is fixedly fitted to the end of the damping block away from the sleeve, the end of the moving rod away from the damping block is fixedly connected to a fixed plate, and the sleeve is located inside the spring.
[0012] Preferably, a bellows is fixedly mounted on the outer wall of the housing, and the side of the bellows away from the housing is fixedly connected to a fixed plate, with the spring located inside the bellows.
[0013] Preferably, the cross-sectional shape of the housing is "Y" shaped, and the anti-blocking component is located at the inclined side of the housing.
[0014] Compared with the prior art, this utility model has at least the following beneficial effects:
[0015] 1. In the above scheme, the dry anaerobic fermentation raw material is crushed by a crushing component. The crushed dry anaerobic fermentation raw material slides down the lower part of the inner wall of the shell. When the crushed powder accumulates on the inner wall of the shell, a motor drives a rotating rod to rotate. The rotation of the rotating rod drives a cam to rotate. The cam continuously pushes the fixed plate, thereby moving the fixed plate away from the shell. This causes the vertical plate and the top plate to move. When the cam separates from the fixed plate, a spring pulls the fixed plate towards the shell, thereby moving the vertical plate and the top plate into the shell. This pushes the raw material, loosens the accumulated raw material, prevents the crushed raw material from clogging, and improves the stability and reliability of the device during operation.
[0016] 2. In the above scheme, by setting up drying components, when the crushed raw materials fall between the two sets of drying components, heat is generated by electric heating wires to dry the raw materials, reduce the moisture in the raw materials, and thus improve the fermentation effect of the raw materials. The side plate can prevent raw material fragments from falling into the groove and prevent the raw materials from accumulating in the groove. Attached Figure Description

Detailed Implementation
[0033] The dry anaerobic fermentation raw material pretreatment device provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, in order to make the embodiments more detailed, the following embodiments are listed as best and preferred embodiments, and those skilled in the art can also use other alternative methods to implement the invention; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.
[0034] like Figure 1 , Figure 2 and Figure 8-9 As shown, an embodiment of this utility model provides a dry anaerobic fermentation raw material pretreatment device, including: a shell 1, on which a crushing component 2, an anti-clogging component 3, and a drying component 4 are provided; a feed pipe 11 is fixedly connected to the top of the shell 1, and a sealing door 15 is rotatably connected to the outer wall of the shell 1; the anti-clogging component 3 includes a spring 31 provided with elastic force installed on the outer wall of the shell 1, a fixing plate 32 is fixedly mounted on the end of the spring 31 away from the shell 1, a partition 33 is fixedly mounted on the outer wall of the shell 1, and a motor 34 provided with driving force is fixedly mounted on the outer wall of the partition 33. A rotating rod 35 is fixedly mounted at the end of the output shaft 34. A cam 36 is fixedly mounted on the outer wall of the rotating rod 35. A vertical plate 37 is fixedly mounted on the side of the fixed plate 32 near the housing 1. The vertical plate 37 penetrates the housing 1. A top plate 38 is fixedly mounted on the side of the vertical plate 37 away from the fixed plate 32. The cross-sectional shape of the housing 1 is "Y". The anti-blocking component 3 is located at the inclined side of the housing 1. By limiting the shape of the housing 1, it is beneficial for the crushed raw material to slide down along the lower part of the inclined inner wall of the housing 1. At the same time, by limiting the anti-blocking component 3, it is beneficial to improve the unblocking effect of the raw material.
[0035] like Figure 1 , Figure 2 and Figure 5As shown, the crushing assembly 2 includes a second motor 21 installed on the outer wall of the housing 1. A first rotating shaft 22 is fixedly mounted at the end of the output shaft of the second motor 21. A first crushing roller 23 is fixedly mounted on the outer wall of the first rotating shaft 22. A transmission belt 24 meshes with the outer wall of the transmission belt 24. A second rotating shaft 25 meshes with the outer wall of the transmission belt 24. A second crushing roller 26 is fixedly mounted on the outer wall of the second rotating shaft 25. The second rotating shaft 22 is driven to rotate by the second motor 21. The rotation of the first rotating shaft 22 drives the transmission belt 24 and the second rotating shaft 25 to rotate, which in turn drives the first crushing roller 23 and the second crushing roller 26 to rotate. Through the rotation of the two sets of crushing rollers, the raw materials for dry anaerobic fermentation can be crushed, which is beneficial to improving the fermentation efficiency of the raw materials for dry anaerobic fermentation.
[0036] like Figure 2 and Figure 7 As shown, the drying component 4 includes a groove 41 formed in the inner wall of the shell 1. An electric heating wire 42 is fixedly installed on the inner wall of the groove 41, and a side plate 43 is fixedly installed on the inner wall of the groove 41. Several ventilation holes are formed on the outer wall of the side plate 43. There are two sets of drying components 4, and the two sets of drying components 4 are symmetrically distributed on both sides of the inner wall of the shell 1. By setting the drying components 4, when the crushed raw material falls between the two sets of drying components 4, the electric heating wire 42 generates heat to dry the raw material, reduce the moisture in the raw material, and thus improve the fermentation effect of the raw material. The side plate 43 can prevent raw material fragments from falling into the groove 41 and prevent the raw material from accumulating in the groove 41.
[0037] like Figure 2 and Figure 6 As shown, a round rod 12 is rotatably connected to the inner wall of the feed pipe 11, and a baffle 13 is fixedly mounted on the outer wall of the round rod 12. A spring piece 14 is fixedly mounted on the inner wall of the feed pipe 11. The side of the spring piece 14 away from the feed pipe 11 is fixedly connected to the baffle 13. By setting the round rod 12, the baffle 13 and the spring piece 14, it is beneficial to simply block the material when the raw material passes through the feed pipe 11. After feeding is completed, the baffle 13 is reset by the spring piece 14, thereby reducing the feeding speed of the raw material and preventing the raw material from accumulating on the crushing component 2.
[0038] like Figure 3 and Figure 8 As shown, a folded cloth 39 is fixedly mounted on the side of the top plate 38 near the inner wall of the shell 1. The side of the folded cloth 39 away from the top plate 38 is fixedly connected to the shell 1. By setting the folded cloth 39, it is beneficial to seal the connection between the vertical plate 37 and the shell 1, thereby preventing the crushed raw materials from falling out of the shell 1.
[0039] like Figure 4 and Figure 9As shown, a sleeve 311 is fixedly mounted on the outer wall of the housing 1. A damping block 312 is slidably connected to the inner wall of the sleeve 311. A moving rod 313 is fixedly mounted on the end of the damping block 312 away from the sleeve 311. The end of the moving rod 313 away from the damping block 312 is fixedly connected to the fixed plate 32. The sleeve 311 is located inside the spring 31. By setting up the sleeve 311, the damping block 312 and the moving rod 313, it is beneficial for the moving rod 313 to push the damping block 312 to slide inside the sleeve 311 when the spring 31 moves, thereby improving the stability of the spring 31 and the fixed plate 32 when they move, thus ensuring the normal use of the device.
[0040] like Figure 4 and Figure 9 As shown, a bellows 314 is fixedly mounted on the outer wall of the housing 1. The side of the bellows 314 away from the housing 1 is fixedly connected to the fixing plate 32. The spring 31 is located inside the bellows 314. By setting the bellows 314, it is beneficial to protect the spring 31, prevent the spring 31 from being corroded by the outside world, and thus improve the service life of the spring 31.
[0041] The technical solution provided by this utility model, when working, drives the rotating shaft 22 to rotate through the motor 21, and the rotation of the rotating shaft 22 drives the transmission belt 24 and the rotating shaft 25 to rotate, which in turn drives the crushing roller 23 and the crushing roller 26 to rotate. Through the rotation of the two sets of crushing rollers, the raw materials for dry anaerobic fermentation can be crushed.
[0042] The crushed dry anaerobic fermentation raw material slides down the lower part of the inner wall of the shell 1. When the powder obtained after crushing accumulates on the inner wall of the shell 1, the rotating rod 35 is driven to rotate by the motor 34. The rotation of the rotating rod 35 drives the cam 36 to rotate. The cam 36 continuously pushes the fixed plate 32, thereby moving the fixed plate 32 away from the shell 1. This causes the vertical plate 37 and the top plate 38 to move. When the cam 36 separates from the fixed plate 32, the fixed plate 32 is pulled towards the position of the shell 1 by the spring 31. This causes the vertical plate 37 and the top plate 38 to move into the interior of the shell 1, thereby pushing the raw material and loosening the accumulated raw material.
[0043] By setting up the drying component 4, when the crushed raw material falls between the two sets of drying components 4, the electric heating wire 42 generates heat to dry the raw material, reducing the moisture in the raw material and thus improving the fermentation effect of the raw material. The side plate 43 can prevent the raw material fragments from falling into the groove 41 and prevent the raw material from accumulating in the groove 41.
[0044] 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 principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
