DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1 , is a device for separating impurities from kitchen waste slurry disclosed in an embodiment of the present invention, comprising a storage bin 1, the storage bin 1 comprising a feed port 101 and a discharge port 102, the feed port 101 being connected to the discharge pipe of the pulping equipment, and the discharge port 102 being connected to the feed pipe, see Figure 2 , a blocking rod array 2 is fixedly installed in the storage bin 1, and the blocking rod array 2 is arranged below the feed port 101. The blocking rod array 2 includes a plurality of blocking rods arranged in a rectangular row. A first slag outlet 11 is opened on the side of the storage bin 1 where the blocking rod array 2 is not fixed. A wire cleaning plate 21 is slidably installed on the blocking rod array 2. The wire cleaning plate 21 has a plurality of through holes corresponding to the blocking rods. A driving member 22 is fixedly installed in the storage bin 1, and the output end of the driving member 22 is fixedly connected to the wire cleaning plate 21. Please refer to Figure 3 A screening plate 3 is hinged on the inner wall of the accommodating bin 1. The screening plate 3 is located below the barrier bar array 2. The free end of the screening plate 3 is higher than the hinged end. A second slag outlet 12 is provided in the accommodating bin 1 at the hinged end of the screening plate 3. A vibration drive 31 is fixedly installed in the accommodating bin 1. The output end of the vibration drive 31 is fixedly connected to the free end of the screening plate 3. The discharge port 102 is located below the screening plate 3.

[0031] Specifically, a barrier bar array 2 is set in the accommodating bin 1. The barrier bar array 2 intercepts the entangled objects through dense barrier bars, so that the entangled objects are hung on the barrier bars, and the wire cleaning plate 21 is driven to slide by the driving member 22, and the entangled objects hung on the barrier bars are pushed out at regular intervals. A screening plate 3 is set under the barrier bar array 2 to screen solid particles such as debris.

[0032] In this way, by screening out the solid impurities in the slurry, the solid impurities entering the delivery pump are reduced, thereby reducing the wear and blockage of the delivery pump part and improving the separation efficiency of the centrifuge.

[0033] In some feasible embodiments, the storage bin 1 includes two rectangular bin bodies, one for mounting the barrier bar array 2 and the other for mounting the screening plate 3. The barrier bar is a cylindrical rod, the driving member 22 is an electric push rod, and the cleaning plate 21 is a porous plate. The barrier bar corresponds to the through-holes of the cleaning plate 21, so that when the cleaning plate 21 slides, the entangled material intercepted on the barrier bar is pushed out of the first slag outlet 11, thereby cleaning the barrier bar. To reduce the possibility of slurry leakage from the first slag outlet 11, a bend can be provided at the bottom of the feed port 101 to allow the slurry to enter the barrier bar array 2 away from the first slag outlet 11. The screening plate 3 is a mesh plate, and the vibration drive 31 can be configured as an oscillating motor or a reciprocating drive mechanism as used in the prior art.

[0034] As a specific embodiment of the device for separating impurities from kitchen waste slurry provided in the application, please refer to Figure 4 The blocking rod side circumferential array has a plurality of rectangular wire cleaning grooves 201 arranged along the axial direction, and the through holes of the wire cleaning plate 21 are provided with rectangular protrusions corresponding to the wire cleaning grooves 201.

[0035] Generally speaking, there may be strips with smaller diameters in the entangled objects, which may get stuck in the gap between the cleaning plate 21 and the blocking rod during the sliding cleaning process of the cleaning plate 21. By setting the cleaning groove 201 and the corresponding protrusions, the protrusions push the entangled objects during sliding cleaning, reducing the possibility of entering the gap between the cleaning plate 21 and the blocking rod.

[0036] Furthermore, the barrier bar array 2 protrudes from the first slag outlet 11 , and when the wire cleaning plate 21 slides to one end of the barrier bar array 2 close to the first slag outlet 11 , the wire cleaning plate 21 protrudes from the barrier bar array 2 .

[0037] It should be understood that by arranging the blocking bar array 2 to protrude from the first slag outlet 11 and the wire cleaning plate 21 to protrude from the blocking bar array 2, the wire cleaning plate 21 can completely push the entangled material out of the blocking bar array 2 and the accommodating bin 1, thereby reducing the possibility of bringing the entangled material back during the resetting process of the wire cleaning plate 21.

[0038] Further, see Figure 1 The first slag outlet 11 is provided with a spray pipe 23 , and the water outlet of the spray pipe 23 faces the cleaning plate 21 .

[0039] It should be understood that spraying the surface of the cleaning plate 21 through the spray pipe 23 facilitates flushing of the entanglements pushed out by the cleaning plate 21, further reducing the possibility of bringing back the entanglements during the resetting of the cleaning plate 21.

[0040] Furthermore, the spray pipe 23 is provided with a push switch, which is located on the sliding path of the wire cleaning plate 21. When the wire cleaning plate 21 slides to one end of the blocking bar array 2 close to the first slag outlet 11, the push switch is pressed.

[0041] It should be understood that the cleaning plate 21 intermittently cleans the entangled material. By setting a press switch, the spray pipe 23 is triggered when the cleaning plate 21 moves to the first slag outlet 11, and the spray pipe 23 is shut down when it is reset, thereby reducing water waste.

[0042] In some feasible embodiments, the spray pipe 23 is connected to a water pump, and the push switch is a normally open push button switch, which is turned on when the wire cleaning plate 21 is pressed and turned off after the wire cleaning plate 21 is reset.

[0043] As another specific embodiment of the device for separating impurities from kitchen waste slurry provided by the application, please refer to Figure 1 A buffer bin 13 is provided below the feed port 101 , an electric valve is provided at the bottom of the buffer bin 13 , and a barrier bar array 2 is provided below the electric valve.

[0044] In combination with specific usage scenarios, when the wire cleaning plate 21 is cleaning the entangled objects, if slurry enters, the wire cleaning plate 21 will push the intercepted entangled objects to the end away from the first slag outlet 11 when it is reset. By setting a buffer bin 13 and an electric valve, the slurry feed is cut off through the electric valve and opened again after the wire cleaning plate 21 cleans the entangled objects and is reset.

[0045] As a specific embodiment of the device for separating impurities from kitchen waste slurry provided in the application, please refer to Figure 3 The screening plate 3 is provided with multiple layers, and the sieve holes of the multiple layers of screening plate 3 gradually decrease from top to bottom.

[0046] It should be understood that by providing multiple layers of screening plates 3, the slurry can be screened more finely, the wear and blockage of the delivery pump can be further reduced, and the separation efficiency of the centrifuge can be further improved.

[0047] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
