DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] A device for squeezing and separating food waste, such as Figure 1 , 2As shown in , 3, it comprises a square tube 1, the left and right ends of the square tube 1 are closed, a pressing block 2 is installed in an airtight sliding fit in the square tube 1, the outer periphery of the pressing block 2 is in sliding contact with the inner periphery of the square tube 1, a driving device for driving the pressing block 2 to move left and right is provided on the square tube 1, a plurality of liquid outlet holes 3 are provided on the side wall of the square tube 1, a filter screen is provided in the liquid outlet hole 3, a feed port 4 is provided on the upper side of the square tube 1, and a slag discharge port 5 is provided on the lower side of the square tube 1, characterized in that: the feed port 4 and the slag discharge port 5 are respectively provided with two, and the plurality of liquid outlet holes 3 are provided with a filter screen. The liquid outlet 3, the feed port 4, and the slag discharge port 5 are symmetrically distributed on the square tube 1. When the pressing block 2 is in the middle of the square tube 1, the pressing block 2 blocks the two feed ports 4. The outer side of the slag discharge port 5 is provided with an inclined guide groove 20. The lower side of the guide groove 20 is provided with a food waste bin. The food waste bin is not drawn in this embodiment. The guide groove 20 is fixedly installed on the square tube 1. The outer side of the slag discharge port 5 is movably provided with a baffle 6. The driving device controls the movement of the baffle 6 through a linkage structure. The utility model has a simple structure and an ingenious design. Through the left and right movement of the pressing block 2, the continuous squeezing of the food waste is realized, which greatly improves the work efficiency, can meet the actual needs, and is suitable for promotion. When using the utility model, firstly, the pressing block 2 is driven by the driving device to perform reciprocating left and right movements. When the pressing block 2 moves to the left to expose the feed port 4 on the right, the food waste needs to be put into the feed port 4 on the right. Then, the pressing block 2 moves to the leftmost side and then moves in the opposite direction. The pressing block 2 first covers the feed port 4 on the right, so that the food waste cannot be put into the feed port 4 on the right. Then, the food waste put into the feed port 4 on the right is squeezed, and the liquid generated by the squeezing of the food waste is discharged through several liquid outlet holes 3. In this process, the feed port 4 on the left is exposed, and food waste can be put into it. When the pressing block 2 moves to the rightmost side and then moves in the opposite direction to the left, it drives the baffle 6 to move and open to expose the slag discharge port 5 on the right. The squeezed solid residue falls from the slag discharge port 5 and falls into the food waste bin through the guide groove 20. Then, the above operation is repeated to realize the solid-liquid separation of the food waste.

[0017] Specifically, as shown in the figure, the inner side of the guide groove 20 in this embodiment is fixedly installed with a pressure plate 21, and the baffle 6 can be in contact with the upper side of the pressure plate 21. The pressure plate 21 increases the bearing capacity of the baffle 6, so that when the pressing block 2 squeezes the food waste, the baffle 6 can well block the food waste.

[0018] Furthermore, as shown in the figure, the outer side of the square tube 1 described in this embodiment is fixedly installed with a box body 30, the guide grooves 20 pass through the side walls of the box body 30 respectively, a liquid collecting port 31 is opened on the lower side of the box body 30, and several supporting legs 32 are fixedly installed on the periphery of the box body 30. The liquid collecting port 31 can be connected to the oil-water separator through a water pipe, and the water pipe and the oil-water separator are not drawn in this embodiment. When the pressing block 2 squeezes the food waste, the liquid in the food waste will spray from several liquid outlets 3. The existence of the box body 30 can block the spraying path of the liquid, thereby protecting the environment; the oil-water mixture flowing out of the liquid collecting port 31 is separated by the oil-water separator and the oil and water are discharged to the external oil barrel and water barrel respectively.

[0019] Furthermore, as shown in the figure, the driving device described in this embodiment includes a reciprocating screw 40, and the two ends of the reciprocating screw 40 are respectively rotatably mounted on the square tube 1 through the shaft seat, and the outer peripheral thread of the reciprocating screw 40 is equipped with a nut 41, and the nut 41 is fixedly connected to the pressing block 2 through the slide rod 42. The lower side of the square tube 1 is provided with a slide groove 43, and the slide rod 42 is slidably mounted in the slide groove 43. The inner wall of the slide groove 43 is respectively in sliding contact with the outer wall of the slide rod 42, and the pressing block 2 always blocks the slide groove 43. One end of the reciprocating screw 40 is fixedly connected to the output shaft of the motor 44, and the motor 44 is fixedly mounted on the square tube 1. Under the sliding cooperation between the slide rod 42 and the slide groove 43, the nut 41 can only move left and right along the reciprocating screw 40, and the rotation of the output shaft of the motor 44 drives the reciprocating screw 40 to rotate, thereby driving the nut 41 to move left and right, thereby driving the pressing block 2 to move left and right in the square tube 1 through the slide rod 42.

[0020] Furthermore, as shown in the figure, the linkage structure of this embodiment includes a fixing ring 50, two fixing rings 50 are provided and fixedly mounted on the nut 41 respectively, the fixing rings 50 are fixedly mounted on the nut 41 respectively through connecting rods, and are symmetrically distributed on the nut 41, and positioning rods 51 are movably mounted in the fixing rings 50 respectively, and the inner peripheries of the fixing rings 50 are respectively in sliding contact with the outer peripheries of the corresponding positioning rods 51, and the positioning rods 51 are respectively connected to the corresponding fixing rings 50 through springs 52, and the springs 52 are sleeved on the positioning rods 51. One end of the spring 52 is fixedly connected to the side wall of the positioning rod 51, and the other end of the spring 52 is fixedly connected to the corresponding fixing ring 50. The upper end of the positioning rod 51 is an arc surface, which is an arc less than half a circle. Arc holes 53 are respectively provided on the baffle 6. The upper end of the positioning rod 51 can be installed in the corresponding arc hole 53. The baffle 6 is installed on the square tube 1 through the spring rod 7. The fixed ends of the spring rod 7 are respectively fixedly installed on the square tube 1, and the movable ends of the spring rod 7 are respectively fixedly connected to the side walls of the baffle 6. When the nut 41 is located at the leftmost side of the reciprocating screw 40, the left side of the pressing block 2 squeezes the food waste in the left cavity of the square tube 1 to the minimum volume, and the corresponding upper end of the positioning rod 51 is located in the arc hole 53. Therefore, at this time, the positioning rod 51 can drive the baffle 6 to move. As the reciprocating screw 40 continues to rotate, the nut 41 moves to the right, driving the pressing block 2 to move to the right. When the feed port 4 on the left is in a state of being about to be located on the left side of the pressing block 2, the spring rod 7 is in the shortest state. The pressing block 2 continues to move, and the positioning rod 51 cannot continue to drive the baffle 6 to move. Therefore, the upper end of the positioning rod 51 slides out of the arc hole 53. At this time, the baffle 6 is reset under the elastic force of the spring rod 7, and the baffle 6 on the right is the same.

[0021] Furthermore, as shown in the figure, a plurality of vertical plates 60 are fixedly installed on the upper side of the square tube 1 in this embodiment, and the plurality of vertical plates 60 surround the two feed ports 4. A dividing plate 61 is provided between the two feed ports 4, and the dividing plate 61 is fixedly installed on the square tube 1. When the kitchen waste is placed between the plurality of vertical plates 60, the kitchen waste can fall into the feed ports 4 respectively under the action of the dividing plate 61, and will not be accumulated on the square tube 1.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
