The initial end of the transportation stage 230 is located below the moving gate 220, the terminal end of the transportation stage 230 is located above the discharge port of the outer housing 200, and the transportation stage 230 is used for receiving the solid waste discharged from the moving gate 220 and conveying the solid waste to the discharge port of the outer housing 200; the solid waste collection box 300 is disposed below the discharge hole of the outer case 200, for collecting the solid waste discharged from the outer case 200; the drainage sloping table 240 is arranged below the transport table 230, the transverse direction of the drainage sloping table 240 is consistent with the transverse direction of the transport table 230, the bottom end of the drainage sloping table 240 is far away from the discharge hole, and the drainage sloping table 240 is used for receiving waste liquid dripped from the transport table 230; the liquid inlet of the second waste liquid collecting pipeline 500 is communicated to the inside of the outer shell 200 and is located at the bottom of the drainage ramp 240. For discharging the waste liquid from the bottom of the drainage ramp 240 to an external collection tank.

In the embodiment of the present invention, the small-package liquid material is put into the outer case 200 through the hopper 100, and then pulverized by the pulverizer 210 to destroy the package of the small-package liquid material, so that the liquid can flow out of the package. The crushed material crushed by the crusher 210 is stopped by the movable gate 220, stacked and left standing, and the waste liquid flows to the bottom of the crushed material stack. And then, collecting the waste liquid at the bottom of the crushed material pile by using a first waste liquid collecting pipeline to realize the primary separation of the solid waste and the waste liquid. After the waste liquid is preliminarily collected, the movable gate 220 is opened, and the pulverized material pile is dropped on the transport table 230, so that the pulverized material flows inside the outer case 200. After the pulverized material falls on the transportation table 230, the transportation table 230 transports the pulverized material to the discharge port of the outer case 200 and discharges the pulverized material. Need not artifical partial shipment, effectively solve artifical partial shipment process scene dirty and disorderly poor, cause certain technical problem of harm to workman's occupational health and environment. It is worth mentioning that, in the process of transporting the crushed materials by the transporting table 230, the written waste liquid is received by the drainage sloping table 240, the waste liquid is drained to the bottom of the sloping table, and the waste liquid is recovered by the second waste liquid collecting pipeline, so that the second solid-liquid separation is realized, and the solid-liquid separation effect of the dangerous waste materials is improved.

Preferably, the movable gate 220 is obliquely disposed inside the outer casing 200, one edge of the movable gate 220 is hinged to the inner wall of the outer casing 200, and the liquid inlet of the first waste liquid collecting pipeline 400 is disposed at the bottom end of the movable gate 220. Specifically, as shown in the embodiment of fig. 1, one side edge of the movable gate 220 is hinged to the inner wall of the outer shell 200, so that the movable gate 220 can swing up and down, and when the movable gate 220 swings up, the side edge far away from the hinged end is higher than the hinged end, so that the movable gate 220 intercepts crushed materials crushed by the crusher 210, and waste liquid in a crushed material pile can be collected to the inclined bottom of the movable gate 220 along the inclined surface of the movable gate 220 and enter the first waste liquid collecting pipe. When the moving gate 220 swings downward, an edge of a side far from the hinge end is made lower than the hinge end, so that the pulverized material pile crushed by the pulverizer 210 slides down along the inclined surface of the moving gate 220 and finally falls on the transportation table 230. Specifically, the moving shutter 220 may be driven to swing up and down by a motor.

Preferably, the inside of the outer case 200 is provided with a drainage slope plate 260, and the drainage slope plate 260 is located above a side edge far from the hinged end of the moving gate 220. Specifically, since the movable gate 220 is movably disposed inside the outer casing 200 in a swinging manner, a gap may exist between an edge of the side far from the hinged end and the outer casing 200 for the movable gate 220 to normally swing. To avoid waste liquid dripping from the crusher 210 from passing directly through the gap. Referring to fig. 3 and 4, the drainage sloping plate 260 is arranged above the side edge far away from the hinged end of the movable gate 220, so that the drainage sloping plate 260 covers the gap, the waste liquid falling on the drainage sloping plate 260 flows onto the movable gate 220, and the problem that the waste liquid dropping from the pulverizer 210 directly passes through the gap is solved.

Preferably, the included angle α between the moving gate 220 and the horizontal plane is 20 ° to 30 °. Specifically, if the included angle between the movable gate 220 and the horizontal plane is less than 20 °, the inclination of the movable gate 220 is insufficient, so that the waste liquid is difficult to collect at the bottom end of the movable gate 220, which is not beneficial to the collection of the waste liquid by the first waste liquid collecting pipeline. If the included angle between the movable gate 220 and the horizontal plane is more than 30 degrees, although waste liquid is favorably collected to the bottom end of the movable gate 220, the load of the hinged edge of the movable gate 220 is large, and the service life of the movable gate 220 is short.

Since the shredder 210 is inside the outer casing 200, sparks are generated when the shredder 210 shreds small packages of liquid material, such as some 300ml or 500ml chemical reagent glass bottles, and there is a risk of explosion. In this embodiment, the inert gas is introduced into the outer shell 200 through the inert gas source 800 for protection, so that sparks generated in the crushing process of the small-package liquid material are effectively avoided, and the explosion is avoided. In the preferred embodiment, inert gas source 800 is nitrogen, which is readily available and inexpensive.

Preferably, the first waste liquid collecting pipeline 400 and the second waste liquid collecting pipeline 500 share the same power pump 600, and the power pump 600 is used for providing drainage power for the first waste liquid collecting pipeline 400 and the second waste liquid collecting pipeline 500. Specifically, the power pump 600 has two input ends, the terminal end of the first waste liquid collecting pipeline 400 is communicated with one input end of the power pump 600, and the terminal end of the second waste liquid collecting pipeline 500 is communicated with the other input end of the power pump 600. So, drive first minute liquid collection pipeline and second waste liquid pipeline simultaneously through a power pump 600 to reduce power pump 600's quantity, do benefit to the cost that reduces solid-liquid separation system.

Preferably, the first and second waste liquid collecting pipes 400 and 500 are respectively provided with basket filters 700, and the basket filters 700 are used for filtering out solid waste mixed in the waste liquid. So, filter the waste liquid through set up basket filter 700 on first waste liquid collection pipeline 400 and second waste liquid collection pipeline 500, effectively avoid in partial solid waste disintegrating slag gets into power pump 600 to guarantee that management and second waste liquid collection pipeline 500 can normal operating are collected to first waste liquid.
