TECHNICAL FIELD

[0001] The utility model relates to garbage treatment device technical field, especially relate to a kind of extrusion drainage board for garbage compression equipment, improve the shape of drainage hole, reduce the plugging rate of plate hole. BACKGROUND

[0002] Among the collection and processing equipment of garbage, there is a kind of equipment for garbage compression box, which is used to transport the collected garbage with high water content to the garbage transfer station for compression treatment. After the garbage compression box is full, it is extruded from one side to the other side, and the liquid extruded is discharged from the liquid discharge end of the other side. The liquid discharge end is connected with a liquid collection tank to drain to a sewage tank, and the garbage after extrusion is further processed. Among them, the liquid discharge end of the garbage compression box is a liquid discharge plate arranged at the end of the box. The plate wall is relatively thick, and the overall plate surface is arranged with liquid discharge holes in rows and columns. The general opening rate of the overall plate surface is about 10%. The size of the hole for domestic garbage is generally a circular hole with a hole diameter of 30mm or a square hole or a waist-shaped hole with a similar cross-sectional area. However, regardless of the structure of the liquid discharge hole, the size of the domestic garbage cannot be estimated, and it is not convenient to strictly classify and process. During the use of the extrusion hole, the hole is often blocked. It takes time and water to clean these blocked holes, which affects the efficiency of garbage treatment and circulation. SUMMARY

[0003] The utility model provides a kind of extrusion drainage board for garbage compression equipment to solve the problem that the plate hole of the extrusion drainage board of garbage compression box in prior art is prone to blockage, improve the structure of plate hole, reduce the problem of plate hole blockage.

[0004] The utility model discloses a kind of extrusion drainage board for garbage compression equipment, including installation in the drainage end of extrusion box drainage plate, the drainage plate is arranged with several drainage holes, it is characterized in that, the drainage hole is from liquid inlet side to liquid outlet side enlarged waist-shaped inverted conical hole.

[0005] The utility model has the beneficial effects that in the case where the opening rate is unchanged, the shape of the drainage hole is selected as a waist-shaped hole, which has a longer overall length and a smaller width compared to a circular hole with the same through area, so the amount of garbage passing through is small, and the amount of liquid discharged remains unchanged to ensure the efficiency of leachate discharge during garbage compression. Meanwhile, the hole shape is designed as an inverted conical hole from the liquid inlet side to the liquid outlet side, so the hole size is smaller on the liquid inlet side and larger on the liquid outlet side. This design effectively blocks the garbage in the box and reduces the probability of hole blockage, while ensuring the efficiency of leachate discharge during garbage compression.

[0006] Further, the length direction of the waist shape of the drainage hole is horizontally arranged.

[0007] Further, the drainage hole is horizontally arranged in several rows on the drainage plate, and the hole positions in each row are staggered.

[0008] Further, the width of the waist-shaped inverted taper hole of the drainage hole is tapered from the liquid inlet side to the liquid outlet side.

[0009] Further, the taper of the waist-shaped inverted taper hole expanding from the liquid inlet side to the liquid outlet side is 1: (3.5-4).

[0010] Further, the opening rate of the drainage hole on the surface of the drainage plate is 9-12%, the hole width of the liquid inlet side of the waist-shaped inverted taper hole is 9-11mm, and the hole length is 65-75mm. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 It is a front view (partial view) of the extrusion drainage plate for garbage compression equipment of the utility model.

[0013] The following structural drawings will explain the extrusion drainage plate for garbage compression equipment of the utility model in detail.

[0014] As shown in Figure 1 and Figure 2 The extrusion drainage plate for garbage compression equipment of the utility model comprises a drainage plate 1 installed at the drainage end of an extrusion box, a plurality of drainage holes 2 arranged on the drainage plate 1, and the drainage hole 2 is a waist-shaped inverted taper hole expanding from the liquid inlet side to the liquid outlet side.

[0015] In the utility example, the waist-shaped length direction of the drainage hole 2 is horizontally arranged; and the drainage hole 2 is horizontally arranged on the drainage plate 1 in several rows, and the hole positions in each row are staggered; the width (short direction) of the waist-shaped inverted taper hole of the drainage hole 2 is tapered from the liquid inlet side to the liquid outlet side, and the taper of the waist-shaped inverted taper hole expanding from the liquid inlet side to the liquid outlet side is 1: (3.5-4).

[0016] On the whole drainage plate, the opening rate of the drainage hole 2 on the surface of the drainage plate 1 is 9-12%, and the size adaptability of the domestic garbage in the garbage transfer station. The hole width of the liquid inlet side of the waist-shaped inverted taper hole is 9-11mm, and the hole length is 65-75mm.

[0017] The extrusion drainage plate of the garbage compression equipment is subjected to the following extrusion drainage performance experiment: the drainage plates with circular drainage holes, square drainage holes and waist-shaped drainage holes are subjected to extrusion experiment; according to the particularity of domestic garbage in the garbage compression station, the drainage hole size is designed to ensure that the leachate in the domestic garbage can pass through the drainage holes after compression and that the domestic garbage cannot pass through the drainage holes to block the drainage holes. The precondition of the experiment is to ensure that the garbage compression amount and the garbage specifications are consistent, the through sectional area of all holes is consistent, the opening rate is consistent, and the garbage blocking conditions inside all holes are compared under the same compression area and compression pressure, the hole compression blocking rate is calculated according to the number of blocked holes; the final experimental results show that: the overall length of the waist-shaped inverted cone hole is longer than that of the circular hole with the same area, which can ensure that the leachate of the garbage compression has higher water outlet efficiency, and the hole structure is formed into an inverted cone type, the hole inlet is small and the hole outlet is large, the number of garbage compression blocking the drainage holes is obviously smaller than that of other hole structures, thereby effectively proving that the water outlet efficiency of the garbage compression of the drainage plate structure of the waist-shaped inverted cone hole of the utility model is high, and the blocking rate is low.

[0018] The extrusion drainage plate of the garbage compression equipment is not limited to the structure size of the equipment during the extrusion of domestic garbage, the size of the hole and the arrangement mode of the hole can be appropriately changed in the arrangement direction or the size of the hole on the basis of the inverted cone hole structure according to the difference of the application scene.
