[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1-10 As shown, an oil inlet structure for a frying box of a deep fryer is provided. The frying box 1 is provided with an oil inlet 11 and an oil outlet. In this embodiment, hot oil flows into the frying box 1 from the oil inlet 11 and then flows out of the frying box 1 from the oil outlet. The oil inlet 11 is used to transport external hot oil into the interior of the frying box 1. A diversion assembly located on the side of the oil inlet 11 is detachably provided inside the frying box 1. The diversion assembly includes a conveying plate 2, a diversion plate 3, a guide plate 4, and an oil baffle plate 5. The conveying plate 2 and the diversion plate 3 are fixedly installed inside the frying box 1, and the oil inlet 11 is located on the side of the conveying plate 2 away from the diversion plate 3.

[0030] Before frying, hot oil is supplied to the frying tank 1. When the external hot oil enters the frying tank 1 through the oil inlet 11, it first passes through a flow divider. The flow divider reduces the pressure of the hot oil, diverts it, and regulates the flow rate, ensuring that the hot oil enters the frying area of ​​the frying tank 1 evenly. The oil inlet pressure and flow rate are stable and uniform. The hot oil heats and fries the material (products to be fried), and pushes the material and impurities forward along the flow direction. Impurities are eventually discharged through the oil outlet of the frying tank 1, and the fried products are subsequently output by an external conveyor. Furthermore, the guide plate 4 and the oil baffle 5 are movable (can move up and down) to regulate the hot oil flow rate, thus meeting the frying process requirements of different materials (materials floating on the surface, partially floating, or sinking), and making the oil temperature inside the fryer more uniform. After long-term use, the flow divider can be disassembled for cleaning, facilitating subsequent cleaning of the oil inlet 11 of the frying tank.

[0034] The hot oil after pressure reduction and shunt is guided by the guide plate 4 to flow in two directions, the upper half of the hot oil flows out through the first guide opening 45, the hot oil flowing out from the first guide opening 45 is relatively more (the size of the first guide opening 45 is larger than the size of the second guide opening 46), and the position of the first guide opening 45 is flat with the liquid surface of the hot oil inside the frying box 1, after the hot oil flows out, the material falling from the upper left of the frying box 1 is pushed forward while the material is heated and fried.

[0035] The hot oil of the lower half part flows out through the guide hole 421 and the second guide hole 46, and the hot oil flowing out from the guide hole 421 can push the material forward, and the hot oil flowing out from the second guide hole 46 can push the impurities falling on the bottom wall of the frying tank 1 forward along the bottom wall of the frying tank 1.

[0037] The guide plate 4 can move up and down, which is realized by the first slot 441 and the second slot 422.

[0038] Specifically, the connecting piece 44 is locked at different positions of the mounting plate 12 through the mounting hole and the first slot 441, and the middle part of the locking screw 7 is locked at different positions of the vertical plate 42 through the second slot 422, so that the position of the guide plate 4 can be adjusted, that is, the guide plate 4 can move up and down.

[0039] Since the oil baffle 5 is on the same vertical line with the end of the horizontal plate 41, the hot oil flowing out through the guide hole 421 and the second guide hole 46 is again distributed by the oil baffle 5 and divided into two parts, the upper half part of the hot oil flows out through the first oil baffle 52, and the lower half part of the hot oil flows out through the second oil baffle 53. The hot oil flowing out from the first oil baffle 52 and the second oil baffle 53 respectively pushes the material falling in the frying tank 1 or the impurities located on the bottom wall of the frying tank 1 forward, and the material or the impurities will reach the oil outlet of the frying tank 1, and the impurities will be filtered out from the oil outlet. The discharge of the impurities ensures the quality of the hot oil. At the same time, the oil baffle 5 avoids the backflow of the material.

[0040] The oil baffle 5 can also be adjusted by moving up and down. After the position of the oil baffle 5 is changed, the size of the first oil baffle port 52 and the second oil baffle port 53 changes. The flow of hot oil in the first oil baffle port 52 and the second oil baffle port 53 can be adjusted according to the characteristics of different materials. The first oil baffle port 52 and the second oil baffle port 53 adjust the flow of hot oil, which can meet the needs of different materials (material floating on the liquid surface, half floating, and sinking to the bottom) for frying process, and make the oil temperature in the frying tank 1 more uniform.

[0041] Specifically, the end of the locking screw 7 is locked in different positions of the oil baffle 5 through the third slot 51, so that the position of the oil baffle 5 can be adjusted, that is, the oil baffle 5 can move up and down.

[0044] Preferably, a gasket is arranged between the first locking nut and the first gusset plate 13 and between the second locking nut and the second gusset plate 14.

[0045] As an implementable manner, a plurality of flow distribution holes 32 are uniformly arranged on the flow distribution plate 3, and a first installation gap is left between the top of the flow distribution plate 3 and the top wall of the frying tank 1 and between the bottom of the flow distribution plate 3 and the bottom wall of the frying tank 1. The first installation gap is designed to facilitate the installation and fixation of the flow distribution plate 3 to the inside of the frying tank 1. Although hot oil flows out from the first installation gap, it does not affect the overall oil inlet effect. The hot oil flows out through the plurality of flow distribution holes 32 to realize pressure reduction and distribution. The flow distribution holes 32 cover the entire flow distribution plate 3, and the hot oil passing through the conveying plate 2 is blocked and distributed by the flow distribution plate 3. Since the total cross-sectional area of all the flow distribution holes 32 of the flow distribution plate 3 is enlarged again compared with the total cross-sectional area of all the conveying holes 21 of the conveying plate 2, the flowing hot oil realizes pressure reduction and distribution again.

[0046] As an implementable manner, the conveying plate 2 is in a U-shaped structure, and is fixedly connected at a side away from the flow distributor 3 of the flow guide plate 4.

The second installation gap is designed to facilitate the installation and fixation of the conveying plate 2 to the inside of the frying box 1. Although hot oil flows out from the second installation gap, it does not affect the overall oil feeding effect. After the hot oil enters the inside of the frying box 1 from the oil inlet 11, it flows out between the conveying plate 2 and the flow distributor 3 through the conveying holes 21 of the conveying plate 2, and the flowing hot oil realizes pressure reduction and flow distribution.

[0047] Among them, the flow rate of hot oil in the middle conveying holes 21 is greater than that in the two end conveying holes 21. In order to keep the flow rate of hot oil in each conveying hole 21 consistent, the dowel pin 23 is arranged through the middle conveying holes 21. The dowel pin 23 plays a role in flow distribution.

A fixed hole 33 is arranged at the side of the flow distributor 3 close to the conveying plate 2. The fixed screw rod 22 is fixedly connected with a fixed nut through the fixed hole 33. The top and bottom of the conveying plate 2 are in contact with the top and bottom of the flow distributor 3, respectively. The fixed screw rod 22 and the fixed nut are used to fix the conveying plate 2 on the flow distributor 3.

The frying machine is externally connected with a boiler, the boiler heats oil, and the oil pump 65 is communicated with the boiler through an external pipe. When the oil pump 65 is started, the oil pump 65 conveys the hot oil in the boiler into the inside of the frying tank 1 through the fourth pipe 64, the third pipe 63, the second pipe 62, the first pipe 61 and the guide hole 611, and then the hot oil is subjected to pressure reduction and flow regulation by the shunt assembly.

[0051] When the oil pump 65 conveys the hot oil, the middle position of the first pipe 61 is the fastest to enter the oil, so the middle pressure of the first pipe 61 is large, and therefore the flow rate of the hot oil in the middle part of the guide hole 611 and the delivery hole 21 is greater than that in the two end guide holes 611 and delivery holes 21. In order to keep the flow rate of the hot oil in each guide hole 611 and delivery hole 21 consistent, the column pin 23 is arranged through the middle part of the guide hole 611 and the delivery hole 21, the column pin 23 plays a role of shunt, the end of the column pin 23 passes through the delivery hole 21 and the guide hole 611 into the inside of the first pipe, the column pin 23 reduces the cross-sectional area of the middle part of the guide hole 611 and the delivery hole 21, so that the hot oil is dispersed and shunted to the two end guide holes 611 and delivery holes 21, and the hot oil is subjected to pressure reduction and shunting.

[0052] As an implementable manner, the second pipe 62 is provided with a plurality of second pipes 62, the top of each of the plurality of second pipes 62 is fixedly connected with and communicated with the first pipe 61, the bottom of each of the plurality of second pipes 62 is fixedly connected with and communicated with the third pipe 63, and the two ends of the fourth pipe 64 are fixedly connected with and communicated with the middle part of the third pipe 63 and the outlet of the oil pump 65, respectively. When the oil pump 65 is started, the oil pump 65 conveys the hot oil in the boiler into the plurality of second pipes 62 through the fourth pipe 64 and the third pipe 63, and then the hot oil is conveyed into the inside of the frying tank 1 through the first pipe 61 and the guide hole 611.

After the hot oil enters the inside of the frying tank 1 from the import hole 611, first, the hot oil is pressure-divided and flows out between the conveying plate 2 and the shunt plate 3 through the plurality of conveying holes 21 on the conveying plate 2, then the hot oil is pressure-divided and flows out between the shunt plate 3 and the guide plate 4 through the plurality of shunt holes 32 on the shunt plate 3. The hot oil is guided by the guide plate 4 to flow in two directions, the upper half of the hot oil flows out through the first guide opening 45, and the lower half of the hot oil flows out through the guide hole 421 and the second guide opening 46.
