[0029] Figure 2 This is a schematic structural diagram of a cylinder provided in an embodiment of the utility model.

[0030] Among them, there are a silo 1, a reflux component 2, a reflux pipe 21, a valve 22, a water filter component 3, a water collecting tank 31, a cylinder 32, a screw rod 33, and a power mechanism 34. DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0032] The utility model provides a kitchen waste reflux heating device, see Figure 1 and Figure 2 , Figure 1 The structure diagram of the restaurant kitchen waste reflow heating device is shown in FIG. 1 , which includes: a silo 1, a reflow component 2, a water filter component 3 and an external conveying pipeline;

[0033] The feed end of the water filter assembly 3 is connected to the bottom of the silo 1;

[0034] The water filter component 3 has a slurry discharge end and a solid waste discharge end. The water filter component 3 is used to separate the solid waste from the slurry in the kitchen waste. The slurry discharge end is connected to an external conveying pipeline.

[0035] The feed end of the reflux component 2 is communicated with the external conveying pipeline, and the discharge end of the reflux component 2 is communicated with the silo 1 .

[0036] It should be noted that the feed end of the reflux component 2 is connected to the external conveying pipeline, and the discharge end of the reflux component 2 is connected to the silo 1. The reflux component 2 can re-introduce the warm organic slurry in the external conveying pipeline into the silo 1 to melt the grease and / or ice in the silo 1, thereby avoiding the waste of heat in the organic slurry. Moreover, since the organic slurry can be recycled, the unheated food waste can be directly put into the silo 1 for melting, thereby simplifying the treatment process of the food waste.

[0037] It is worth noting that the organic slurry in the external conveying pipeline is introduced into the silo 1 through the reflux component 2 only when the temperature is greater than a certain level, because the grease and / or ice in the food waste cannot be melted when the temperature in the organic cooling is low.

[0038] In the embodiment of the utility model, the feed end of the water filter component 3 is connected to the bottom of the silo 1, and the solid waste in the food waste is separated from the slurry through the water filter component 3, and the slurry discharge end of the water filter component 3 is connected to the external conveying pipeline, the feed end of the reflux component 2 is connected to the external conveying pipeline, and the discharge end of the reflux component 2 is connected to the silo 1. Through the above-disclosed food waste reflux heating device, the organic slurry with temperature in the external conveying pipeline can be introduced into the silo 1 again through the reflux component 2, so that the grease and / or ice in the silo 1 is melted, thereby avoiding the heat in the organic slurry from being wasted.

[0039] Specifically, the reflux component 2 includes: a water pump, a reflux pipe 21 and a valve 22;

[0040] The water outlet of the water pump is connected to the first end of the return pipe 21, and the water inlet of the water pump is connected to the external delivery pipeline;

[0041] The second end of the reflux pipe 21 is in communication with the silo 1;

[0042] The valve 22 is disposed at the second end of the return pipe 21 .

[0043] It should be noted that the water outlet of the water pump is connected to the first end of the return pipe 21, the water inlet of the water pump is connected to the external conveying pipeline, and the second end of the return pipe 21 is connected to the silo 1, and the valve 22 is set at the second end of the return pipe 21. Then, when the external ambient temperature is at room temperature (the grease is not solidified), the valve 22 can be closed to limit the reflux of the organic slurry in the external conveying pipeline, thereby improving the solid-liquid separation efficiency of the kitchen waste reflux heating device; and when the external ambient temperature is low (the grease is solidified and / or there are ice cubes), the valve 22 and the water pump can be opened to introduce the heated organic slurry in the external conveying pipeline into the silo 1 for reuse, thereby avoiding the waste of heat in the organic slurry.

[0044] Specifically, the second end of the reflux pipe 21 is communicated with the top of the silo 1 .

[0045] It should be noted that when the second end of the reflux pipe 21 is connected to the top of the silo 1, the organic slurry can impact the solidified grease and / or ice from top to bottom when flowing out from the second end of the reflux pipe 21, thereby accelerating the melting of the grease and / or ice, and thus improving the separation efficiency of the food waste reflux heating device.

[0046] Further, the water filter assembly 3 includes: a water collection tank 31, a cylinder 32, a spiral rod 33 and a power mechanism 34;

[0047] The cylinder 32 and the silo 1 are arranged at a preset angle, and the lower end of the cylinder 32 is connected to the discharge end of the silo 1;

[0048] The screw rod 33 is rotatably disposed in the cylinder 32. The screw rod 33 is rotated to drive the solid waste at the lower end of the cylinder 32 to be discharged from the discharge port of the cylinder 32. The discharge port of the cylinder 32 is located at the upper end of the cylinder 32.

[0049] The power mechanism 34 is in transmission connection with the screw rod 33;

[0050] The cylinder 32 is provided with a plurality of through holes around its periphery for the passage of organic slurry;

[0051] The water collecting tank 31 is disposed below the cylinder 32 , and a discharge end of the water collecting tank 31 is connected to an external conveying pipeline.

[0052] It should be noted that the barrel 32 and the silo 1 are arranged at a preset angle, and the lower end of the barrel 32 is connected to the discharge end of the silo 1; the screw rod 33 is rotatably arranged in the barrel 32, and the rotation of the screw rod 33 is used to drive the solid waste at the lower end of the barrel 32 to be discharged from the discharge port of the barrel 32, and the discharge port of the barrel 32 is located at the upper end of the barrel 32; the power mechanism 34 is transmission-connected with the screw rod 33; a plurality of through holes for the passage of organic slurry are opened in the circumference of the barrel 32; the water collecting tank 31 is arranged below the barrel 32, and the discharge end of the water collecting tank 31 is connected to the external conveying pipeline, and then when the power mechanism 34 drives the screw rod 33 to rotate, it can drive the food waste to move from the lower end of the barrel 32 to the upper end of the barrel 32, and during the movement, the organic slurry in the food waste will flow out from the through hole of the barrel 32 to the water collecting tank 31 under the action of its own gravity, thereby realizing solid-liquid separation.

[0053] Furthermore, the thread pitch of the screw rod 33 gradually decreases along the axial direction of the screw rod 33 , wherein the thread pitch at the lower end of the screw rod 33 is greater than the thread pitch at the upper end of the screw rod 33 .

[0054] It should be noted that the thread pitch of the screw rod 33 is gradually reduced along the axial direction of the screw rod 33, and the thread pitch at the lower end of the screw rod 33 is made greater than the thread pitch at the upper end of the screw rod 33. When the solid waste moves from the lower end of the cylinder 32 to the upper end of the cylinder 32, as the thread pitch of the screw rod 33 decreases, the rotation of the screw rod 33 can squeeze the solid waste, so that the organic slurry in the solid waste is squeezed out and flows through the through hole of the cylinder 32 to the sump 31 for collection.

[0055] Specifically, the power mechanism 34 is a motor.

[0056] It should be noted that the power mechanism 34 may be a motor, or other mechanisms capable of driving the screw rod 33 to rotate, such as a diesel engine, a gasoline engine, a steam engine, or other power mechanisms 34 .

[0057] Specifically, the preset angle ranges from 35° to 60°.

[0058] It should be noted that the preset angle may be 35°, 60°, or 47°, and those skilled in the art may select any angle between 35° and 60° as required.

[0059] Furthermore, the food waste reflow heating device also includes: a heating device for heating the food waste in the silo 1 .

[0060] It should be noted that, by providing a heating device for heating the food waste in the silo 1, the food waste can be directly placed in the silo 1 in cold weather, and the food waste in the silo 1 can be heated by the heating device to melt the solidified fat and / or ice.

[0061] Specifically, the heating device is a steam heating device.

[0062] It should be noted that the heating device may be a steam heating device or other devices (such as electric heating devices) capable of heating the food waste in the silo 1, and those skilled in the art may make conventional replacements according to needs.

[0063] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
