Description

Technical Field

[0001] The invention belongs to the technical field of restaurant kitchen waste treatment, and in particular relates to a closed restaurant kitchen waste collection and transportation system. Background Art

[0002] Urban kitchen waste is mainly generated by canteens or catering stores in schools, enterprises, government agencies, etc. where people are relatively concentrated. It is mainly food processing waste, food residues and other high-moisture organic waste, which is easy to rot and deteriorate, and it is easy to emit odors, causing air pollution and affecting the surrounding environment. At the same time, the collection, transportation and treatment of kitchen waste is also related to the hygiene of the food processing site (kitchen) and people's food safety.

[0003] The main treatment method for urban food waste is to collect and transport it for centralized reduction, harmless treatment and resource utilization. In order to effectively alleviate the "NIMBY effect" of food waste treatment plants, food waste treatment plants are generally built in areas with relatively few residents. Therefore, the collection and transportation of food waste has become an important part of the food waste treatment process.

[0004] The collection and transportation of food waste refers to the process of placing, transferring, and finally transporting the scattered food waste to the food waste treatment plant. Compared with the "NIMBY effect" caused by the centralized treatment of food waste in the treatment plant, the surrounding air pollution caused by dumping, transfer, odor leakage, etc. during the collection and transportation of food waste is shorter in duration, but with the driving of the transport vehicle, its impact is wider. In addition, compared with the centralized treatment of food waste, its collection and transportation process is mostly in schools, enterprises, commercial streets and other places with dense populations, and the impact of environmental pollution caused by the collection and transportation process is more serious. Therefore, achieving efficient collection and transportation of food waste and avoiding odor leakage, pathogenic microorganism transmission and other problems caused by the collection and transportation of food waste are of great significance to improving the urban sanitation system and building urban ecological civilization.

[0005] However, in the prior art, direct contact with personnel cannot be avoided in most of the collection and transportation processes of food waste. During the transfer process, the stench emitted by the food waste can easily be emitted into the air, causing secondary pollution, which is not conducive to environmental protection during the treatment of food waste. Summary of the invention

[0006] The main purpose of the present invention is to provide a closed restaurant kitchen waste collection and transportation system, aiming to achieve closed treatment of the entire restaurant kitchen waste collection and transportation process, and avoid garbage exposure and direct contact between personnel during the restaurant kitchen waste collection and transportation process.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A closed kitchen waste collection and transportation system, comprising:

[0009] A garbage bin for storing garbage, wherein the garbage bin is provided with a feed inlet and a discharge inlet, the feed inlet is provided with an openable and closable bin cover, and the discharge inlet is provided with a normally closed discharge valve;

[0010] A transfer bin for transferring garbage, wherein the transfer bin is detachably connected to the garbage bin, the discharge port is sealedly connected to the feeding port of the transfer bin, and the feeding port is provided with an openable and closable cover;

[0011] The unloading mechanism is arranged on the transfer bin and is used to control the unloading valve to open the unloading port so as to unload the garbage to the transfer bin.

[0012] Specifically, a negative pressure air intake port is provided on the side wall of the feeding port, the negative pressure air intake port is connected to a negative pressure fan, and a deodorization module is also provided between the negative pressure air intake port and the negative pressure fan.

[0013] Specifically, the deodorizing module is activated carbon.

[0014] Specifically, a foot pedal for controlling the opening and closing of the bin cover is provided at the bottom of the trash bin, and the foot pedal is linked to the bin cover through a connecting rod mechanism.

[0015] Specifically, a feeding flap which can be turned around a rotating axis is provided in the feed port.

[0016] Specifically, the foot pedal controls the feeding flap to flip 180 degrees through a connecting rod mechanism at the same time.

[0017] Specifically, the feeding flap is arranged obliquely in the feeding port.

[0018] Specifically, the discharge valve includes two gate plates, two slide grooves and two return springs. The two slide grooves are respectively opened on the two opposite side walls of the discharge port. The two gate plates are respectively slidably connected in the corresponding slide grooves, and the two return springs are connected between the corresponding gate plates and the slide grooves.

[0019] Specifically, the unloading mechanism is a pair of mechanical arms that drive the two gate plates to slide in the corresponding slide grooves.

[0028] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] See also Figure 1-Figure 3 A closed food and kitchen waste collection and transportation system includes a garbage bin 1 for storing garbage, a transfer bin 2 for transferring garbage, and a discharge mechanism 3. The top of the garbage bin 1 is provided with a feed port 4, the bottom is provided with a discharge port 5, the feed port 4 is provided with a closable box cover 6, the discharge port 5 is provided with a normally closed discharge valve 7, the transfer bin 2 can be detachably connected to the garbage bin 1, and a closable cover body (not shown in the figure) is provided on the feeding port 8, and the discharge mechanism 3 is used to control the discharge valve 7 to open the discharge port 5. When it is necessary to transfer the garbage in the garbage bin 1 to the transfer bin 2, it is only necessary to open the cover body and dock the garbage bin 1 with the transfer bin 2. At this time, the discharge port 5 of the garbage bin 1 is sealed and connected with the feeding port 8 of the transfer bin 2. The discharge valve 7 is controlled by the discharge mechanism 3 to open the discharge port 5, and the garbage can be unloaded to the transfer bin 2.

[0032] In this embodiment, an openable and closable box cover 6 is provided on the top of the garbage bin 1, which can effectively prevent the garbage odor from overflowing. After the food waste temporarily stored in the garbage bin 1 is connected to the transfer bin 2, the garbage in the garbage bin 1 can be unloaded to the transfer bin 2 through the unloading mechanism 3, and after the transit transportation in the transfer bin 2, it is transferred to the storage bin of the food waste treatment plant through a closed connection. After the food waste is generated, the whole process of closed collection and transportation is realized, avoiding direct contact between materials and air or personnel during the collection and transportation of the food waste.

[0033] It is understandable that in actual application, in order to facilitate the movement of the transfer bin 2, the transfer bin 2 is installed on a transport vehicle, and the transfer bin 2 can quickly move back and forth between the garbage bin 1 and the food waste treatment plant. In order to facilitate the temporary placement or cleaning and disinfection of the transfer bin 2, the transfer bin 2 can be quickly disassembled from the transport vehicle.

[0034] See also Figure 1 and Figure 3 In some embodiments, a negative pressure air intake port (not shown in the figure) is provided on the side wall of the feeding port 8 of the garbage bin 1, the negative pressure air intake port is connected to the negative pressure fan 9, and a deodorization module (not shown in the figure) is also provided between the negative pressure air intake port and the negative pressure fan 9. Among them, the deodorization method can adopt physical adsorption and chemical adsorption, and in this embodiment, activated carbon is used for physical adsorption.

[0035] In this embodiment, a feeding port 8 is provided in the middle of the operating bin, and the feeding port 8 is used to connect with the discharge port 5 of the garbage bin 1 to transfer the food waste in the garbage bin 1 to the bin body of the operating bin. A negative pressure fan 9 is installed on the side of the inner wall of the feeding port 8, which is used to form a negative pressure environment in the garbage bin 1 after the operating bin is connected with the garbage bin 1, so as to improve the transfer efficiency of the food waste in the garbage bin 1 and avoid the odor therein from leaking into the air to cause pollution to the greatest extent.

[0036] See also Figure 2 In other embodiments, a foot pedal 10 for controlling the opening and closing of the box cover 6 is provided at the bottom of the garbage bin 1, and the foot pedal 10 is linked to the box cover 6 through a connecting rod mechanism (not shown in the figure). In this embodiment, when putting garbage, the worker only needs to step on the foot pedal 10 to drive the box cover 6 to open through the connecting rod mechanism. When the foot pedal 10 is released, the box cover 6 is re-covered on the feed port 4 of the garbage bin 1 under its own gravity or the action of the return spring 703. The foot pedal is connected to the barrel cover through the lever principle, which is convenient and labor-saving.

[0037] See also Figure 1 and Figure 2 In other embodiments, a feeding flap 11 that can be flipped around a rotating axis is provided in the feed port 4. The feeding flap 11 covers the feed port 4 when it is in a balanced state. When garbage is thrown into the feed port 4, the garbage will break the balance of the feeding flap 11. The feeding flap 11 rotates around under the action of the garbage's own weight to open the feed port 4. At this time, the garbage can slide along the feeding flap 11 into the inner cavity of the trash bin 1. When all the garbage on the feeding flap 11 enters the trash bin 1, the feeding flap 11 is reset to a balanced state under the action of its own gravity or the reset force of the reset member, and the feed port 4 is re-covered.

[0038] Of course, it should be noted that in actual design, the feeding flap 11 can also be controlled by a connecting rod mechanism. When the food waste is put in, first step on the pedal on the side of the garbage bin 1, and the pedal drives the box cover 6 to open through the action of the connecting rod mechanism, and the food waste falls into the feeding flap 11 through the feeding port 4 below the box cover 6. When the weight of the food waste after the feeding is large, under the gravity of the food waste put in, the feeding flap 11 completes a 180° rotation, and the food waste in the feeding port 4 is dumped into the inner cavity of the garbage bin 1. When the weight of the food waste put in is small and its gravity is insufficient to drive the feeding flap to complete a 180° rotation, after releasing the pedal, the box cover 6 is closed under the elastic force of the spring device connected thereto, and at this time, the rotating shaft on the feeding flap 11 is toggled while the connecting rod mechanism is reset, and rotates in the same direction as the dumping of the garbage, prompting the feeding flap 11 to complete a 180-degree rotation, and the food waste therein is dumped into the inner cavity of the garbage bin 1.

[0039] It should be noted that the working principle of the connecting rod mechanism and the box cover 6 has been maturely applied in the existing trash cans, and will not be described in detail here. In addition, in order to facilitate the pouring of food waste, the feeding flap 11 is tilted in the feeding port 4. As for the specific linkage structure between the connecting rod mechanism and the feeding flap 11, they are all existing technologies and will not be described here.

[0040] See also Figure 2 Specifically, the discharge valve 7 includes two gate plates 701, two slide grooves 702 and two return springs 703. The two slide grooves 702 are respectively provided on two opposite side walls of the discharge port 5. The two gate plates 701 are respectively slidably connected in the corresponding slide grooves 702, and the two return springs 703 are connected between the corresponding gate plates 701 and the slide grooves 702. In this embodiment, by driving the gate plates 701 to move in the slide grooves 702, the two gate plates 701 are moved closer to or farther from each other, so that the opening area of ​​the discharge port 5 can be controlled, and the discharge amount can be flexibly controlled.

[0041] See also Figure 3 In the actual design, the unloading mechanism 3 is a pair of mechanical arms 301 that drive two gate plates 701 to slide in the corresponding slide grooves 702, and a force-bearing hole 12 matching the corresponding mechanical arm 301 is provided on the gate plate 701. When the garbage bin 1 is full of food waste, the garbage bin 1 is docked with the operation bin, and the fixing groove on the base of the garbage bin 1 is stuck on the docking seat of the operation bin to complete the fixation of the garbage bin 1. Then, the mechanical arm 301 installed on the docking seat extends into the force-bearing hole 12. At this time, the reset spring 703 is compressed under the pulling force of the mechanical arm 301, and the gate plate 701 connected thereto is opened, and the food waste falls into the docking port through the unloading port 5 of the garbage bin 1, and then falls into the feeding port 8 of the operation bin, and then enters the bin body.

[0042] After the above operations, the closed food waste collection and transportation system designed by the present invention realizes the closed collection and transportation of food waste from its generation to its entry into the food waste treatment plant for terminal treatment, avoiding direct contact between the collection and transportation personnel and the surrounding air and the food waste, and is very suitable for the collection and transportation of urban food waste.
