Abstract
Description
Technical Field
[0001] This utility model belongs to the field of leaching technology, specifically relating to a spray overflow device for leaching. Background Technology
[0002] During the extraction process, the solvent needs to be in full contact with the oil to extract more oil. The extractor is the device used to extract oil from the oil. The oil moves forward at a low speed on a filter screen. Several solvent-providing devices, or spray devices, are arranged above the oil, spraying the solvent evenly and in equal amounts onto the surface of the oil. The solvent penetrates downwards and contacts the oil, and the extracted oil is filtered through the filter screen and falls into an oil collection hopper. It is then pumped back to the spray device for repeated spraying. Because the mixed oil carries away a large amount of powder during the extraction process, the circulating mixed oil passes through the spray device. The overflow tank in the spray device is used for secondary distribution of the mixed oil, balancing the solvent distribution across the extraction width and preventing unevenness on the surface of the oil layer. In actual production, the bottom hole of the overflow tank is easily blocked; long-term operation of the overflow tank will cause powder to accumulate, filling the entire tank cavity and causing uneven spraying; the powder in the overflow tank is not easy to clean; for oil with fibrous material, it is easy to get stuck on the tank teeth, affecting the overflow and causing the overflow tank to lose its function of secondary distribution of mixed oil, which directly affects the leaching residual oil rate. Utility Model Content
[0003] The purpose of this invention is to provide a spray overflow device to solve the technical problem of high residual oil leaching rate caused by sludge accumulation in existing overflow tanks.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a spray overflow device, characterized in that it includes:
[0005] A spray assembly includes a spray pipe with liquid outlet holes on the spray pipe;
[0006] The overflow assembly is a split structure, including a first overflow tank and a second overflow tank arranged opposite each other; the mixed oil flows through the outlet hole of the spray pipe to the first overflow tank, then flows through the second overflow tank and overflows into the oil, and the overflow assembly is used to prevent sludge accumulation.
[0007] This invention designs the overflow component as a split structure, including a first overflow tank and a second overflow tank, which shortens the residence time of the mixed oil from the spray pipe in the overflow component, avoids the sedimentation of powder in the mixed oil, and allows the powder to fall onto the oil material below with the mixed oil, thereby solving the problem of material accumulation in the overflow tank, while retaining the effect of secondary distribution of mixed oil, thus achieving excellent leaching effect.
[0008] To address the technical challenge of installing the overflow assembly, this invention employs the following technical solution: the overflow assembly further includes connecting plates disposed at both ends of the first overflow channel and the second overflow channel, used to fix the overflow assembly to the leaching tank side plate. Connecting plates are fully welded to both ends of the first and second overflow channels, and the connecting plates are mounted on a guide positioning assembly, which is then mounted on the leaching tank side plate.
[0009] To solve the technical problem of how to implement the first overflow channel, this utility model adopts the following technical solution, wherein the first overflow channel includes:
[0010] The first baffle, which is set vertically, is used to prevent the mixed oil from overflowing from the first overflow trough;
[0011] The first guide vane is inclined downwards and positioned at the lower end of the first baffle.
[0012] The first guide overflow plate is inclined upward and disposed at the lower end of the first guide plate. The connection between the first guide overflow plate and the first guide plate forms an oil storage tank for uniformly distributing the mixed oil. The end of the first guide overflow plate is provided with a first serrated overflow section.
[0013] When the mixed oil is sprayed, it impacts the surface of the first guide plate and the first baffle, passes through the oil storage tank, and falls directly onto the triangular arc sawtooth of the first guide overflow plate, so that the mixed oil can be evenly distributed on the surface of the oil.
[0014] To solve the technical problem of mixed oil with fluffy fibers getting stuck in the sawtooth pattern during circulation, this utility model adopts the following technical solution: the first sawtooth overflow part includes a first peak sawtooth and a first valley sawtooth arranged in sequence. The first peak sawtooth and the first valley sawtooth are rounded to ensure that the fluffy mixed oil will not get stuck on or stuck on the peaks and valleys of the sawtooth during circulation.
[0015] To address the technical problem of how to implement the second overflow channel, this utility model adopts the following technical solution, wherein the second overflow channel includes:
[0016] The second baffle is vertically arranged to prevent the mixed oil from overflowing from the second overflow trough; the second guide plate is inclined downward at the lower end of the second baffle.
[0017] The second guide overflow plate is vertically arranged at the lower end of the second guide plate to evenly distribute the mixed oil; the end of the second guide overflow plate is provided with a second serrated overflow section.
[0018] If the flow rate is too high, some of the mixed oil will be impacted onto the inner surface of the second overflow channel. The second overflow channel also has a second baffle, a second guide plate, and a vertically downward-facing second guide overflow plate with triangular serrations. The second baffle blocks the mixed oil from flowing out from the top, and the second guide plate causes the mixed oil to flow downwards. After passing through the vertically downward-facing second guide overflow plate and its triangular serrations, the oil is then evenly distributed to the surface of the oil.
[0019] To solve the technical problem of the positional relationship between the first baffle and the second baffle, the present invention adopts the following technical solution: the height difference between the second baffle and the first baffle is 1.5-2.5 times the diameter of the spray pipe.
[0020] To solve the technical problem of the positional relationship between the liquid outlet and the first overflow tank, the present invention adopts the following technical solution: the liquid outlet is inclined and faces the first guide plate of the first overflow tank.
[0021] The mixed oil coming out of the irregularly shaped liquid outlet of the spray pipe will flow to the first baffle side of the first overflow tank. Its flow direction is towards the first baffle and the first guide plate. The first baffle can prevent the mixed oil from flowing out from the upper end of the straight section. The mixed oil can only flow downward and to the left along the surface of the first guide plate.
[0022] To solve the technical problem of how to realize the liquid outlet hole, the present invention adopts the following technical solution: the liquid outlet hole is an irregularly shaped hole with a structure that is larger at the top and smaller at the bottom.
[0023] To solve the technical problem of material accumulation at the bottom of the spray pipe, the present invention adopts the following technical solution: a slag chute is provided on the spray pipe, located below the liquid outlet and connected to the liquid outlet, so that the powder at the bottom of the spray pipe will flow away from the slag chute.
[0024] To solve the technical problem of how to implement the slag chute, this utility model adopts the following technical solution: the opening area of the slag chute is smaller than the opening area of the liquid outlet hole.
[0025] The slag discharge port includes an arc transition section, a square section, and a semi-circular section arranged from top to bottom. The arc transition section is connected to the liquid outlet hole, and the arc transition section has a structure that is larger at the top and smaller at the bottom. Attached Figure Description

[0037] 300 guide positioning component. Detailed Implementation
[0038] The present invention will be further described below with reference to the accompanying drawings.
[0039] like Figure 1 As shown, the spray overflow device 10 includes a spray assembly 100, an overflow assembly 200, and a guide and positioning assembly 300.
[0040] like Figure 1 As shown, the spray assembly 100 includes a spray pipe 110, which is horizontally arranged. A liquid inlet 140 is installed at one end of the spray pipe 110, and a blind plate 150 is installed at the other end. A liquid outlet 120 is provided on the spray pipe. In one embodiment, the liquid outlet 120 is inclined.
[0041] In one embodiment, such as Figure 5 As shown, the liquid outlet hole 120 is an irregularly shaped hole with a structure that is larger at the top and smaller at the bottom, and is arranged at equal intervals along the axial direction of the spray pipe.
[0042] The spray assembly is used to supply the mixed oil, which enters the spray pipe from the inlet at a certain flow rate. Several irregularly shaped holes are opened at the lower angle of the spray pipe. When the mixed oil fills the inner cavity of the spray pipe, it flows out from the holes. Regardless of the flow rate, the mixed oil in each hole falls into the overflow groove at the bottom of the spray pipe.
[0043] In one embodiment, such as Figure 5 As shown, a slag discharge port 130 is provided on the spray pipe 110, which is located below the liquid outlet and connected to the liquid outlet.
[0044] In one embodiment, the opening area of the slag discharge port 130 is smaller than the opening area of the liquid outlet port 120. For example... Figure 7 As shown, the slag discharge port 130 includes an arc transition portion 131, a square portion 132, and a semi-circular portion 133 arranged from top to bottom. The arc transition portion 131 is connected to the liquid outlet 120, and the arc transition portion 131 has a structure that is larger at the top and smaller at the bottom.
[0045] There are several equidistant irregularly shaped liquid outlet holes on the lower side of the spray pipe. The bottom of the irregularly shaped liquid outlet holes is connected to the slag chute. The opening area of the slag chute is smaller than that of the irregularly shaped liquid outlet holes. The diameter of the slag chute gradually increases from the slag chute hole away from the irregularly shaped liquid outlet hole to the diameter at the connection between the slag chute and the irregularly shaped liquid outlet hole. The arc of the semicircular part of the slag chute below the irregularly shaped liquid outlet hole is tangent to and aligned with the axis of the spray pipe.
[0046] The irregularly shaped oil outlet and sludge discharge port design ensures that no powder will accumulate inside the spray pipe, and the powder will automatically flow out with the flow of the mixed oil.
[0047] When the mixed oil flows inside the spray pipe, a small amount of powder will also be deposited at the bottom of the spray pipe. Each irregular hole at the bottom of the spray pipe has a slag chute directly below it. The slag chute is located at the bottom of the spray pipe and faces directly downwards. The cross-sectional area of the slag chute directly below the irregular hole increases in size. Therefore, the powder at the bottom of the spray pipe will flow away from the slag chute. As the amount of powder increases, the larger area of the slag chute will cause more powder to flow away with the mixed oil.
[0048] There are two guide positioning components 300. The spray pipe 110, guide positioning components 300, blind plate 150, etc. are integrated into one unit. That is, the spray pipe 110 passes through the inner hole of the guide positioning component 300. The guide positioning components 300 are set at both ends of the spray pipe 110. The guide positioning components 300 at both ends of the spray pipe 110 are coaxially fixed to the two side plates of the leaching tank. The spray pipe 110 can rotate around the axis and move along the axis inside the guide positioning component 300.
[0049] The overflow assembly 200 is a split structure, including a first overflow groove 210 and a second overflow groove 220 disposed opposite to each other. In one embodiment, such as Figure 2 As shown, the first overflow channel 210 includes a first baffle 211, a first guide plate 212, and a first guide overflow plate 213.
[0050] The first baffle 211 is set vertically to prevent the mixed oil from overflowing from the first overflow tank.
[0051] The first guide plate 212 is inclined downwards and disposed at the lower end of the first baffle 211. The liquid outlet 120 faces the first guide plate 212. The irregularly shaped liquid outlet 120 is installed obliquely opposite the first overflow groove 210 of the overflow assembly 200. Specifically, the irregularly shaped liquid outlet 120 is exactly opposite to the first guide plate 212 of the first overflow groove.
[0052] The first overflow guide plate 213 is inclined upward and disposed at the lower end of the first guide plate 212. The connection between the first overflow guide plate 213 and the first guide plate 212 forms an oil storage tank 240 for uniformly distributing the mixed oil. The first overflow tank with a small volume oil storage tank ensures the effect of secondary distribution of the mixed oil. The end of the first overflow guide plate 213 is provided with a first serrated overflow section 2130.
[0053] In one embodiment, such as Figure 3 As shown, the first serrated overflow section 2130 includes a first peak serration 2131 and a first valley serration 2132 arranged in sequence. Both the first peak serration 2131 and the first valley serration 2132 are rounded, so that the phenomenon of filament jamming and filament snagging will not occur for some oil containing oil filaments.
[0054] In one embodiment, such as Figure 4 As shown, the second overflow channel 220 includes a second baffle 221, a second guide plate 222, and a second guide overflow plate 223.
[0055] The second baffle 221 is set vertically to prevent the mixed oil from overflowing from the second overflow tank; the height difference between the second baffle 221 and the first baffle 211 is 1.5-2.5 times the diameter of the spray pipe.
[0056] The second guide plate 222 is inclined downward and disposed at the lower end of the second baffle 221.
[0057] The second guide overflow plate 223 is vertically arranged at the lower end of the second guide plate 222 for uniformly distributing the mixed oil; the end of the second guide overflow plate 223 is provided with a second serrated overflow section 2230.
[0058] In one embodiment, the overflow assembly 200 further includes a connecting plate 230 disposed at both ends of the first overflow channel 210 and the second overflow channel 220, for fixing the overflow assembly 200 to the side plate of the leacher.
[0059] The overflow assembly 200 mainly consists of connecting plates 230 at both ends, a first overflow groove 210, and a second overflow groove 220. The mixed oil directly enters the first overflow groove 210. The first overflow groove 210 and the second overflow groove are arranged side by side. The first overflow groove consists of a first baffle 211, a first guide plate 212, and a first guide overflow plate 213. Several triangular serrations are continuously formed at the end of the first guide overflow plate 213, forming a first serrated overflow section 2130. The peak and valley serrations of the triangular serrations all have the same arc, ensuring that the fibrous mixed oil will not get stuck or trapped on the peaks and valleys of the serrations during circulation.
[0060] The first overflow trough is higher on one side and lower on the other. The lower side has several triangular arc serrations. The mixed oil coming out of the irregular liquid outlet of the spray pipe will flow to the first baffle side of the first overflow trough. Its flow direction is towards the first baffle and the first guide plate. The first baffle can prevent the mixed oil from flowing out from the upper end of the straight section. The mixed oil can only flow downward and to the left along the surface of the first guide plate. The first overflow plate, which is connected to the first guide plate, is the lower part of the first overflow channel. The end of the first overflow plate has several triangular arc sawtooths, and the beginning of the first overflow plate is a sloping plate. This sloping plate and the first guide plate form a small oil storage tank. The mixed oil from the spray pipe will pass through this oil storage tank and be distributed to the oil surface. The advantage of the first overflow channel is that it can solve the problem of overflow tank accumulation and also meet the spraying effect. When the mixed oil is sprayed, the mixed oil impacts the surface of the first guide plate and the first baffle, passes through the oil storage tank, and falls directly to the triangular arc sawtooths of the first overflow plate. The mixed oil can be evenly distributed to the oil surface.
[0061] If the flow rate is too high, some of the mixed oil will be impacted onto the inner surface of the second overflow tank. The second overflow tank also has a second baffle, a second guide plate, and a vertically downward-facing second guide overflow plate with triangular serrations. The second baffle prevents the mixed oil from flowing out from the top, while the second guide plate directs the mixed oil downwards, passing through the vertically downward-facing second guide overflow plate and its triangular serrations, before evenly distributing it to the oil surface. Because the first overflow tank has a very small volume, it can only hold the mixed oil for a short time while maintaining a continuous supply. The first overflow tank allows the mixed oil to remain briefly for secondary distribution without causing powder sedimentation.
[0062] The overflow assembly 200 is formed by welding a first overflow channel 210, a second overflow channel 220, and a connecting plate 230 together. The first baffle 211 of the first overflow channel 210 and the second baffle 221 of the second overflow channel 220 are both vertical. The first serrated overflow portion 2130 of the first overflow channel 210 is angled upward to the left, and the second serrated overflow portion 2230 of the second overflow channel 220 is vertically downward. The height difference between the first baffle 211 and the second baffle 221 is 1.5-2.5 times the diameter of the spray pipe. The first overflow channel 210 and the second overflow channel 220 are of the same length and aligned at both ends. Connecting plates 230 are installed and welded at both ends of the first overflow channel and the second overflow channel, requiring full welding.
[0063] The overflow assembly 200 is installed on the two opposite sides of the two guide positioning parts 300 and fixed by bolts. Before fixing, make sure it is level.
[0064] The mixed oil flows through the outlet of the spray pipe to the first overflow tank, then flows through the second overflow tank and overflows into the oil. The overflow assembly is used to prevent sludge accumulation.
[0065] This invention prevents powder from settling in the overflow tank during the circulation of the mixed oil, ensuring continuous spraying and uniform solvent distribution during leaching, thereby improving extraction efficiency.
[0066] This utility model spray overflow device has a self-cleaning effect. Due to the special environment of the leaching section, cleaning the leaching equipment, such as cleaning the accumulated material in the overflow tank, is very troublesome. With this structure and device, the powder carried in the mixed oil will not be deposited in the first overflow tank, but will only flow out with the mixed oil, thus eliminating the need to clean the overflow tank.
[0067] The above embodiments are only for illustrating the technical features and concept of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made according to the spirit and implementation of this utility model should be covered within the protection scope of this utility model.
