Technical Field
[0001] This utility model belongs to the field of environmental protection equipment technology, and relates to transfer warehouses, and in particular to a transfer warehouse for the treatment of kitchen waste. Background Technology
[0002] Food waste, also known as kitchen waste or food scraps, refers to organic waste generated during household, catering service, food processing, and commercial food preparation processes. Food waste is characterized by its high rate of rotting and spoilage, foul odor, and ability to spread bacteria and viruses. Large amounts of food waste are generated daily in both urban and rural areas of my country, and improper disposal can have a severe impact on environmental sanitation.
[0003] In the field of food waste treatment, the transfer warehouse, as an important component of the pretreatment system, is used to collect and transfer food waste. Its structure and performance have a significant impact on the efficiency and cost of the entire treatment line.
[0004] Traditional transfer silos are either square or round, typically equipped with a mixer inside, with the feed pump for downstream equipment placed at the bottom. This design has several drawbacks: First, impurities such as metals and ceramics in food waste easily accumulate at the bottom, causing blockages in the feed pump and pipes, increasing pressure, and leading to frequent malfunctions. This not only increases maintenance costs but also affects processing efficiency. Second, with long-term operation, the impurities settled at the bottom of the transfer silo require manual cleaning, resulting in high labor intensity for workers, increased labor costs, and further impacting processing efficiency. Summary of the Invention
[0005] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide a transfer bin for food waste treatment. This utility model can effectively avoid the blockage of downstream equipment such as feeding pumps, while also improving processing efficiency and reducing the labor intensity and processing cost of workers.
[0006] The technical solution of this utility model is implemented as follows:
[0007] A transfer chamber for food waste treatment includes a chamber body and a feeding pump. An annular mesh is provided inside the chamber body. The mesh is vertically arranged to divide the chamber body into a sedimentation zone and a slurry zone. The slurry zone is located outside the sedimentation zone. An agitator is provided inside the sedimentation zone. The feeding pump is located at the bottom of the slurry zone.
[0008] Furthermore, the agitator includes a rotating shaft and several blades. The rotating shaft is vertically arranged, and the blades are horizontally arranged and evenly distributed along the axial direction of the rotating shaft. The upper end of the rotating shaft is connected to a motor, which facilitates rotation under the drive of the motor to drive the blades to rotate, so as to agitate the kitchen waste in the sedimentation zone.
[0009] Further, the end of the paddle away from the rotating shaft is provided with a stirring head, the stirring head is curved towards one side in an arc shape to increase the stirring effect.
[0010] Further, the bottom of the bin body corresponding to the sedimentation area is provided with a slag discharge port, an inclined variable-pitch screw conveyor is arranged below the slag discharge port, the variable-pitch screw conveyor is provided with a feeding port at the lower end and a discharging port at the upper end, the feeding port of the variable-pitch screw conveyor is connected with the slag discharge port in a corresponding manner, the discharging port of the variable-pitch screw conveyor is higher than the bin body by a certain height, and the pitch of the variable-pitch screw conveyor gradually decreases from the lower end to the upper end.
[0011] Further, the aperture of the screen is 6-10 mm.
[0012] Compared with the prior art, the utility model has the beneficial effects that:
[0013] 1. The screen is arranged in the transfer bin, the bin body is divided into a sedimentation area and a slurry area, the screen can screen the materials, avoids the large-particle materials such as metal and ceramic in the sedimentation area from entering the slurry area, effectively reduces the pressure of the rear-end equipment, avoids the blockage of the rear-end equipment such as the feeding pump, effectively reduces the maintenance cost, and improves the processing efficiency.
[0014] 2. The variable-pitch screw conveyor is arranged at the bottom of the sedimentation area, when the deposits in the sedimentation area deposit to a certain amount, the variable-pitch screw conveyor below the sedimentation area can be opened, the deposits are discharged from the discharging port under the extrusion and pressing of the variable-pitch screw conveyor, manual cleaning of the staff is avoided, and the labor intensity and processing cost of the staff are effectively reduced. Meanwhile, due to the inclined arrangement of the variable-pitch screw conveyor, the slurry in the sedimentation area remains in the sedimentation area and can enter the slurry area and the rear-end equipment under the action of the stirrer.

[0019] The utility model will be further explained in detail in combination with the drawings and specific embodiments.
[0020] Referring to Figure 1 ,Figure 2 and Figure 3 A kitchen waste processing transfer bin comprises a bin body 2 and a feeding pump 1, an annular screen 3 is arranged in the bin body 1, the screen 3 is vertically arranged, thereby dividing the bin body 1 into a sedimentation area a and a slurry area b, the slurry area b is located outside the sedimentation area a, a stirrer is arranged in the sedimentation area a, and the feeding pump 1 is arranged at the bottom of the slurry area b. The screen aperture is 6-10 mm, which can be adjusted according to the application requirements.
[0021] In this way, the material (kitchen waste) enters the sedimentation area of the transfer bin after being crushed at the front end, and the centrifugal effect is generated on the material under the action of the stirrer, so that the metal, ceramic and plastic bag impurities larger than the screen aperture are intercepted in the sedimentation area under the screening action of the screen, the impurities are settled at the bottom of the sedimentation tank under the centrifugal sedimentation action, and the material smaller than the screen aperture enters the slurry area through the screen, and then enters the rear-end equipment such as the feeding pump. Since the metal and ceramic impurities are intercepted in the sedimentation area, the impurities in the slurry area are small and few, which can effectively reduce the pressure of the rear-end equipment, thereby effectively avoiding the blockage of the rear-end equipment such as the feeding pump, and further effectively reducing the maintenance cost and improving the processing efficiency.
[0022] The bin body can be square or circular, and the screen can also be square or circular. In the application, the screen is circular, so that there is no dead zone during stirring, and the stirring is more beneficial.
[0023] In the specific implementation, the stirrer comprises a rotating shaft 7 and a plurality of paddles 5, the rotating shaft 7 is vertically arranged, the paddles 5 are horizontally arranged and uniformly distributed along the axial direction of the rotating shaft 7, and the upper end of the rotating shaft 7 is connected with a motor 6, so as to be rotated under the driving of the motor 6 to drive the paddles 5 to rotate, thereby stirring the kitchen waste in the sedimentation area a.
[0024] Further, the end of the paddle 5 away from the rotating shaft 7 is provided with a stirring head 4, and the stirring head 4 is curved in an arc shape towards one side, so as to increase the stirring effect.
[0025] In this way, the stirring head is arranged at the free end of the paddle, so that the rotating effect of the paddle is increased, and the stirring effect is more obvious. Meanwhile, the stirring head is curved in an arc shape towards one side, which is equivalent to a spoon-shaped structure of the stirring head, so that the usable components such as rice grains in the material are stirred upwards and enter the slurry area through the screen, and the heavy metal and ceramic impurities in the material sink to the bottom of the sedimentation area. The stirring head is a consumable part, which can be detachably arranged on the paddle.
[0026] In the embodiment, the bottom of the bin body 2 corresponding to the sedimentation area a is provided with a slag discharge port, and a variable pitch screw conveyor 8 is obliquely arranged below the slag discharge port, the variable pitch screw conveyor 8 is provided with a feeding port at the lower end and a discharging port at the upper end; the feeding port of the variable pitch screw conveyor 8 is connected with the slag discharge port, the discharging port of the variable pitch screw conveyor 8 is higher than the bin body by a certain height, and the pitch of the variable pitch screw conveyor 8 gradually decreases from the lower end to the upper end.
[0027] In this way, when the sediment in the sedimentation area deposits to a certain amount, the variable pitch screw conveyor below the sedimentation area can be opened, and the slag is discharged from the discharging port under the extrusion and pressing action of the variable pitch screw conveyor, so as to avoid manual cleaning by the staff, and further effectively reduce the labor intensity and processing cost of the staff. At the same time, due to the inclined arrangement of the variable pitch screw conveyor, the slurry in the sedimentation area can be left in the sedimentation area and can enter the slurry area under the action of the stirrer and enter the rear-end equipment.
[0028] Finally, it should be noted that the above embodiments of the present application are only examples for illustrating the present application, and are not a limitation on the embodiments of the present application.
