Description

Technical Field

[0001] The invention relates to the technical field of kitchen waste treatment equipment, and in particular to a current limiting device. Background Art

[0002] Kitchen waste is mainly composed of protein, starch, animal and plant oils and fats, so it has huge potential for resource utilization.

[0003] With the increasing requirements for environmental protection, the effective treatment of food waste has become extremely important. The food waste treatment equipment currently on the market has shortcomings in how the oil-water mixture can flow stably into the oil-water separator. In the prior art, the oil-water mixture after the slag-liquid separation flows directly into the oil-water separator without a flow-limiting structure, which can easily affect the separated oil layer in the oil-water separator, and further affect the working effect of the oil-water separator. Therefore, in order to ensure the stable operation of the oil-water separator, the prior art mostly uses a multi-mesh plate and sets a baffle at the liquid outlet of the slag-liquid separation equipment. The above-mentioned prior art has the problem that when blockage occurs, it cannot be quickly cleaned, affecting the flow-limiting effect, and it is also impossible to clean the blockage without stopping the machine and maintaining the flow-limiting function. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a current limiting device.

[0005] To achieve the above-mentioned purpose, the present invention discloses a flow limiting device, including a working box and a flow limiting module, wherein a liquid passing chamber is arranged in the working box, a liquid outlet communicated with the liquid passing chamber is arranged on one side of the working box, and a flow limiting cover is fixedly arranged on the outer side of the liquid outlet.

[0006] An overflow plate is arranged on the upper half of the flow limiting cover, and a flood spillway is arranged on the overflow plate.

[0007] The lower half of the flow limiting cover is set as the flow limiting working position, and the flow limiting module includes a first flow limiting leaf and a second flow limiting leaf. The first flow limiting leaf can be flipped and set in the flow limiting working position, and it is hinged to the overflow plate. The first flow limiting leaf is used to limit the speed of the liquid flowing out of the liquid outlet. The second flow limiting leaf is obliquely set between the first flow limiting leaf and the liquid outlet. The first flow limiting leaf is driven by a driving device to flip upward, and the second flow limiting leaf is flipped downward and moved to the flow limiting working position to maintain flow limiting, and the residue blocked at the liquid outlet is driven to flow during the flipping process.

[0008] Furthermore, a guide plate is provided at the bottom end of the liquid outlet in a downwardly inclined manner, and the flow limiting cover is fixedly provided between the guide plate and the working box body.

[0009] The flow limiting working position is formed between the overflow plate and the guide plate.

[0010] The overflow port and the liquid outlet are arranged vertically staggered.

[0011] Furthermore, the first flow limiting leaf is hinged to the outer side surface of the overflow plate through a hinge module, so that the first flow limiting leaf is aligned with the overflow plate up and down and is arranged in the flow limiting working position or flipped upward 90° with the overflow plate as the center.

[0012] Furthermore, a swing arm is fixedly provided on the outer side surface of the first current limiting leaf, and the driving device is transmission-linked to the swing arm.

[0013] Furthermore, a lower end of the second flow-limiting leaf is fixedly connected to the inner side surface of the first flow-limiting leaf, and a higher end thereof faces the upper half of the liquid outlet.

[0014] Furthermore, when the first flow limiting leaf or the second flow limiting leaf is arranged in the flow limiting working position, a flow limiting channel is formed between the first flow limiting leaf and the guide plate.

[0015] Furthermore, an overflow position is formed between the overflow plate, the second flow limiting leaf and the liquid outlet, and the overflow port is in conduction with the overflow position.

[0021] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will be combined with Figure 1-Figure 4 The present invention is further described in detail with reference to the accompanying drawings.

[0022] Reference Figure 1 and Figure 2 As shown, a current limiting device is characterized in that it includes a working box 1 and a current limiting module 2, wherein a liquid passing chamber 11 is provided in the working box 1, and the liquid passing chamber 11 is in communication with the top of the working box 1. A liquid outlet 12 is provided on an inner side wall of the liquid passing chamber 11, and the liquid outlet 12 is in communication with the outer side of the working box 1, and the current limiting module 2 is movably provided at the liquid outlet 12.

[0023] A guide plate 13 is provided at the bottom end of the liquid outlet 12, and the guide plate 13 is arranged to be tilted downward. In this embodiment, the guide plate 13 guides the liquid flowing out of the liquid outlet 12 to flow downward.

[0024] A flow limiting cover 3 is arranged between the guide plate 13 and the working box 1, and the bottom and an outer side of the flow limiting cover 3 are respectively fixedly connected to the top of the guide plate 13 and the outer side of the working box 1. In this embodiment, the outer wheel of the flow limiting cover 3 is N-shaped.

[0025] An overflow plate 4 is arranged inside the flow limiting cover 3 , and the top and both sides of the overflow plate 4 are fixedly connected to the top and both sides inside the flow limiting cover 3 respectively.

[0026] Recombination Figure 3 As described above, a flow limiting working position is formed between the bottom of the overflow plate 4 and the top of the guide plate 13. The flow limiting module 2 is movably arranged in the flow limiting working position.

[0027] Furthermore, the bottom of the overflow plate 4 does not exceed the bottom of the liquid outlet 12 to ensure the normal operation of the flow limiting module 2.

[0028] Reference Figure 1 As shown, further, a flood overflow port 41 is provided on the overflow plate 4 , and the flood overflow port 41 is communicated with the liquid outlet 12 .

[0029] Reference Figure 1 and Figure 3 As shown, the flow limiting module 2 includes a first flow limiting leaf 21, a second flow limiting leaf 22 and a swing arm 23. The first flow limiting leaf 21 is flippably arranged in the flow limiting working position, and the outer side surface of the first flow limiting leaf 21 is hinged to the outer side surface of the overflow plate 4 through a hinge module 24. In the initial state, the first flow limiting leaf 21 is flush with the overflow plate 4 up and down, so that a flow limiting channel 5 is formed between the bottom of the first flow limiting leaf 21 and the top of the guide plate 13. One end of the swing arm 23 is fixedly connected to the outer side surface of the first flow limiting leaf 21, and the other end of the swing arm 23 is connected to a driving device (not shown in the figure).

[0030] The driving device is any one of an air cylinder, an oil cylinder, and an electric pole.

[0031] The second flow limiting leaf 22 is fixedly arranged at an angle on the inner side surface of the first flow limiting leaf 21. A vertical section 221 and an oblique section 222 are arranged on the second flow limiting leaf 22. The vertical section 221 is fixedly arranged on the inner side surface of the first flow limiting leaf 21. Specifically, when the first flow limiting leaf 21 is flush with the overflow plate 4 up and down, the oblique section 222 is inclined from the top of the vertical section 221 toward the liquid outlet 12, and the higher end of the second flow limiting leaf 22 faces the upper half of the liquid outlet 12.

[0032] In this embodiment, the higher end of the second flow limiting leaf 22 is located outside the liquid outlet 12 to ensure that when the second flow limiting leaf 22 is turned downward, its higher end does not interfere with the guide plate 13 and cause rotation failure.

[0033] The hinge module 24 in this embodiment is preferably a torsion spring hinge.

[0034] Furthermore, an overflow position 26 is formed between the overflow plate 4 , the liquid outlet 12 and the oblique section 222 , and the overflow port 41 is in communication with the overflow position 26 .

[0035] During operation, the liquid flows into the liquid chamber 11 and flows out through the liquid outlet 12 and the flow limiting channel 5 to the oil-water separation device. The first flow limiting leaf 21 limits the flow of the liquid flowing out of the liquid outlet 12, specifically, the liquid flows into the oil-water separation device at a stable flow rate to ensure the stability of its working effect.

[0036] Some residues are inevitably mixed in the liquid. After long-term use, the residues will accumulate between the first flow-limiting leaf 21 and the guide plate 13, causing the flow-limiting channel 5 to fail. At this time, the liquid flows into the overflow position 26 and flows out from the overflow port 41, thus preventing flooding caused by blockage.

[0037] Recombination Figure 4 As shown, at the same time, the driving device drives the swing arm 23 to move upward, thereby driving the first flow limiting leaf 21 to flip upward 90°. During the process of the first flow limiting leaf 21 flipping upward, the second flow limiting leaf 22 is driven to flip downward. During the process of the second flow limiting leaf 22 flipping downward, the oblique section 222 scrapes the residue downward.

[0038] At the same time, a gap is set between the oblique section 222 and the top of the guide plate 13 to maintain the flow limiting function.

[0039] In this embodiment, the device realizes the flow limiting function by setting the first flow limiting leaf. At the same time, the first flow limiting leaf can be flipped to change the position of the second flow limiting leaf to remove the residue blocking the installation position. Compared with the prior art, this equipment has a self-cleaning function; further, by setting the overflow position and the overflow port, the normal operation of the device is guaranteed when the flow limiting module fails.

[0040] The flow limiting, residue removal and flood overflow structures of this embodiment are simple and reasonable, with low production and maintenance costs and stable and reliable effects.

[0041] Of course, the above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any modifications made according to the spirit of the main technical solution of the present invention should be included in the protection scope of the present invention.
