[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The solid waste pretreatment device according to an embodiment of the utility model will be described below with reference to the accompanying drawings.

[0022] like Figure 1-Figure 3 As shown, the solid waste pretreatment device of the embodiment of the utility model may include: a shell 1, a driving assembly 2 and a feeding mechanism 4, wherein an inclined plate body 11 is provided inside the shell 1, and a plurality of filter holes 12 are provided on the plate body 11.

[0023] It should be noted that the inclination angle of the plate body 11 described in this embodiment is between 30° and 60°, and the specific angle value can be determined according to actual conditions.

[0024] A pressure roller 13 is rotatably connected inside the housing 1 , and the pressure roller 13 is located above the plate body 11 .

[0025] A baffle 14 is connected to the inner wall of the housing 1 , and the baffle 14 is located above the pressure roller 13 .

[0026] It can be understood that the baffle 14 can play the role of separating the shell 1 and supporting the crushing mechanism 3.

[0027] A discharge port 15 is formed on one side of the shell 1 , and the discharge port 15 is located above the plate 11 . A tube 16 is connected to the other side of the shell 1 , and the tube 16 is located below the plate 11 .

[0028] It should be noted that an external material collecting device (not shown in the figure) is provided below the discharge port 15 described in this embodiment, and the external material collecting device can temporarily store the solid waste materials that have been pre-treated.

[0029] In addition, one end of the tube body 16 described in this embodiment is connected to an external liquid collecting device (not shown in the figure), and the external liquid collecting device can collect the liquid generated by separation.

[0030] The driving assembly 2 is disposed on the outer wall of the housing 1 , the driving assembly 2 is connected to one end of the pressure roller 13 , and the feeding mechanism 4 is disposed above the housing 1 .

[0031] Specifically, the solid waste material to be pretreated can be placed inside the feeding mechanism 4 with the help of external feeding equipment (for example: a claw machine, a screw feeder or a conveyor belt, etc.). Under the action of gravity, the solid waste material falls on the plate 11. At this time, under the action of inertia, a part of the liquid is separated from the solid waste material, and the liquid passes through the filter hole 12 into the bottom of the shell 1 for temporary storage.

[0032] Since the plate 11 is arranged at an angle, the solid waste material moves along the plate 11. When the solid waste material reaches the pressing roller 13, the pressing roller 13 can squeeze the solid waste material, which can separate the liquid attached to the solid waste material, thereby improving the solid waste separation effect.

[0033] On the other hand, the volume of the solid waste material can be reduced, making the solid waste material present a flat structure, which is convenient for subsequent treatment of the solid waste material (for example, incineration). After being treated by the pressing roller 13, the solid waste material is discharged to the interior of the external collection device through the discharge port 15. After a period of time, the separated liquid enters the interior of the external liquid collection device through the pipe body 16 for temporary storage.

[0034] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, a crushing mechanism 3 is further provided between the feeding mechanism 4 and the shell 1 , and the crushing mechanism 3 includes a connecting frame 31 , a crushing box 32 and a crushing roller 33 .

[0035] The connection frame 31 is connected to the housing 1 , the crushing box 32 is connected to the connection frame 31 , the crushing roller 33 is installed inside the crushing box 32 , the driving assembly 2 is connected to the crushing roller 33 , and the feeding mechanism 4 is connected to the crushing box 32 .

[0036] It is understandable that the driving assembly 2 drives the crushing roller 33 to rotate, which can crush the solid waste material to be pre-treated, thereby further reducing the volume of the solid waste material and improving the subsequent (eg, incineration) discharge effect of the solid waste material.

[0037] In one embodiment of the present invention, Figure 1 and Figure 3As shown, the feeding mechanism 4 includes a collecting trough 41 , two cover plates 42 and a stopper 43 .

[0038] The aggregate trough 41 is communicated with the crushing box 32 , two cover plates 42 are pivotally connected inside the aggregate trough 41 , a stopper 43 is arranged on the inner wall of the aggregate trough 41 , and the cover plates 42 abut against the stopper 43 .

[0039] It should be noted that a rotating shaft and a torsion spring are provided between the cover plate 42 described in this embodiment and the inner wall of the collecting trough 41 , and the cover plate 42 can be turned over freely under the action of the torsion spring.

[0040] It can be understood that the cover plate 42 can be provided to prevent the debris generated during the crushing process from splashing out through the opening at the upper portion of the aggregate trough 41 .

[0041] In one embodiment of the present invention, Figure 2 As shown, a plurality of rubber strips 51 are provided on the outer wall of the pressing roller 13 , and the rubber strips 51 are in contact with the plate body 11 .

[0042] It is understandable that the rubber strip 51 can intercept the liquid generated during the squeezing process on the plate body 11 to reduce the liquid from flowing out through the discharge port 15 .

[0043] In one embodiment of the present invention, Figure 1 As shown, the housing 1 is provided with an opening 61 , and the opening 61 is located above the plate body 11 .

[0044] It is understandable that the opening 61 facilitates relevant technicians (eg, workers) to observe the working state of the pressure roller 13 and also facilitates maintenance of the interior of the housing 1 .

[0045] In one embodiment of the present invention, Figure 1 As shown, the driving assembly 2 includes a driving motor 21 , a driving wheel 22 , a first driven wheel 23 , a second driven wheel 24 and a transmission belt 25 .

[0046] Among them, the driving motor 21 is installed on the outer wall of the shell 1, the output shaft of the driving motor 21 is connected to the driving wheel 22, one end of the pressure roller 13 passes through the inner wall of the shell 1, one end of the pressure roller 13 is connected to the first driven wheel 23, one end of the crushing roller 33 passes through the inner wall of the crushing box 32, one end of the crushing roller 33 is connected to the second driven wheel 24, and the transmission belt 25 is wound around the driving wheel 22, the first driven wheel 23 and the second driven wheel 24.

[0047] Specifically, during the operation of the driving assembly 2, the driving motor 21 drives the driving wheel 22 to rotate, and under the action of the transmission belt 25, the first driven wheel 23 and the second driven wheel 24 rotate, thereby crushing and filtering the solid waste materials.

[0048] In summary, the solid waste pretreatment device of the utility model drives the pressure roller to rotate through the driving component, and the pressure roller can squeeze the solid waste material on the plate body. On the one hand, it can reduce the volume of the solid waste material, and on the other hand, it can force the liquid attached to the surface of the solid waste material to separate from it, thereby improving the solid waste separation effect.
