Description

Technical Field

[0001] This utility model belongs to the field of chemical engineering extraction technology, and in particular relates to a chemical engineering extraction and separation device. Background Technology

[0002] Extraction separation technology in chemical engineering is a mass transfer process based on the difference in distribution of substances between two phases. Its core principle is to achieve selective transfer by utilizing the difference in solubility or partition coefficient of the target component in immiscible solvents. This physical process does not change the chemical properties of the substance, and through repeated extraction, the target component can be efficiently enriched from the original phase to the extract phase.

[0003] Comparing with Chinese Patent CN219440840U, a chemical engineering extraction and separation device is disclosed, including an extraction tank and a filtration mechanism configured to communicate with the outlet of the extraction tank. The filtration mechanism includes a filter element and a movable scraper that abuts against the front side of the filter element. A solenoid valve is fixedly connected to the outlet. A removable cover is installed at the inlet of the extraction tank. A stirring blade is rotatably connected inside the extraction tank. By setting the filter element and the scraper that moves relative to the filter element, when the filter element filters the solvent, the scraper scrapes the inlet side of the filter element to clean the filter element, thereby preventing the accumulation of impurities on the inlet side of the filter element. This prevents impurities from piling up on the filter element, allowing the filter element to maintain maximum throughput through the gaps in the solvent, and avoiding a decrease in the efficiency of the filter plate in filtering the solvent.

[0004] However, the aforementioned patented scraping of the filter surface can easily cause waste residue to be squeezed into the filter, resulting in blockage. Furthermore, the fixed liquid outlet position can also easily lead to waste residue accumulation, reducing the liquid-solid separation speed. Therefore, a new device needs to be designed.

[0005] The purpose of this invention is to provide a chemical engineering extraction and separation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A chemical engineering extraction and separation device includes a frame assembly for support and fixation. A collection tank is placed at the bottom of the frame assembly. The device also includes a tank assembly mounted on the frame assembly for offset rotation and liquid discharge. A tank cover assembly for feeding and stirring extraction is installed at the top of the tank assembly. A filter bag for separating the extract is disposed below the tank assembly. The filter bag is made of flexible material, and a waste discharge component for telescopic pushing to assist in cleaning waste residue is disposed at the bottom of the filter bag. The frame assembly includes four evenly distributed support legs, with an upper support plate disposed between the tops of the support legs. The middle of each support leg... A lower support plate is provided between the upper and lower support plates, and the edge of the filter bag is pressed and fixed to the lower support plate by a fixing ring; the box assembly includes a box body rotatably mounted in the middle of the upper support plate, a liquid outlet pipe is offset at the bottom of the box body, a liquid outlet valve is installed on the liquid outlet pipe, and a power mechanism for driving rotation is provided on the outside of the box body; the waste discharge assembly includes a fixing frame provided between the support legs, a support cylinder is provided in the middle of the fixing frame, a telescopic cylinder is installed in the middle of the support cylinder, a shielding cylinder is installed at the top telescopic end of the telescopic cylinder, and the top of the shielding cylinder is pressed and fixed to the center of the filter bag by a fixing block.

[0008] Furthermore, the power mechanism includes a passive gear ring fixedly disposed on the outer periphery of the housing and a second motor fixedly mounted on the lower support plate. A drive gear is installed at the output end of the second motor, and the drive gear and the passive gear ring mesh for transmission.

[0009] Furthermore: the passive gear ring and the middle part of the housing are welded together, and the housing is connected to the upper support plate bearing.

[0010] Furthermore, the fixing block is conical and made of 304 stainless steel.

[0011] Furthermore, both the support cylinder and the shielding cylinder are bottomless cylindrical shapes. During extension and retraction, the shielding cylinder completely covers the support cylinder, and the support cylinder completely covers the telescopic cylinder.

[0012] Furthermore: the box cover assembly includes a box cover body, a first motor is installed in the middle of the box cover body, a stirring rod is installed at the output end of the first motor, the stirring rod is inserted into the box cylinder, and a feed hopper is provided on the box cover body away from the first motor.

[0013] Furthermore, the stirring rod has a six-layer, four-lobed structure.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] The shielding cylinder structure is driven by a telescopic cylinder to achieve active control of the filter bag shape (inverted cone to upright cone). In the upright cone state, with the help of water rinsing, waste residue can be quickly guided to be discharged along the inclined surface without disassembly and cleaning, significantly improving cleaning efficiency. The flexible filter bag forms a large filtration area in the inverted cone state, accelerating the liquid-solid separation speed while reducing the risk of filter clogging. The offset liquid outlet pipe combined with the rotating design of the box cylinder ensures that the material is evenly dispersed during the discharge process, avoiding local accumulation and filter bag clogging, and improving the consistency of extract separation. It solves the problems of clogging, low filtration efficiency, and cumbersome cleaning in traditional extraction and separation, and has the advantages of high efficiency, reliability and ease of operation, with significant industrial application value.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

A box cover assembly 3 for feeding and stirring extraction is installed on the top of the box assembly 2. A filter bag 5 for separating the extract is provided below the box assembly 2. The filter bag 5 is made of flexible material. A waste discharge assembly 4 for telescopic pushing to assist in cleaning waste residue is provided at the bottom of the filter bag 5.

[0027] In this embodiment: the frame assembly 1 includes four evenly distributed support legs 101, an upper support plate 102 is provided between the tops of the support legs 101, and a lower support plate 103 is provided between the middle parts of the support legs 101. The edge of the filter bag 5 is pressed and fixed to the lower support plate 103 by a fixing ring 6. The support legs 101 fix the upper support plate 102 and the lower support plate 103. The upper support plate 102 supports the rotation of the box body 201, and the lower support plate 103 fixes and supports the filter bag 5.

[0028] In this embodiment: the box assembly 2 includes a box body 201 rotatably mounted in the middle of the upper support plate 102, an outlet pipe 205 offsetly disposed at the bottom of the box body 201, an outlet valve 206 installed on the outlet pipe 205, and a power mechanism for driving rotation disposed on the outer side of the box body 201; the power mechanism includes a passive gear ring 202 fixedly disposed on the outer periphery of the box body 201 and a second motor 204 fixedly mounted on the lower support plate 103, an active gear 203 installed at the output end of the second motor 204, and the active gear 203 and the passive gear ring 202 meshing and transmitting power. The passive gear ring 202 is welded together with the middle of the cylinder body 201, and the cylinder body 201 is connected to the upper support plate 102 by a bearing. The solvent and solid raw materials are added into the cylinder body 201 from the feed hopper 302 for extraction. After the extraction is completed, the liquid outlet valve 206 is opened, and the extract and waste residue in the cylinder body 201 are discharged from the liquid outlet pipe 205. The first motor 303 drives the active gear 203 to mesh with the passive gear ring 202 to rotate the cylinder body 201, so that the liquid outlet pipe 205 carries the waste residue to the filter screen bag 5 in the circumferential direction to avoid clogging and accelerate filtration.

[0029] In this embodiment: the box cover assembly 3 includes a box cover body 301, a first motor 303 is installed in the middle of the box cover body 301, a stirring rod 304 is installed at the output end of the first motor 303, the stirring rod 304 is inserted into the box cylinder 201, and a feed hopper 302 is provided on the box cover body 301 away from the first motor 303; the stirring rod 304 has a six-layer four-petal structure; the solvent and solid raw materials are added into the box cylinder 201 together from the feed hopper 302, and the box cover body 301 supports the second motor 204 to drive the stirring rod 304 to rotate, thereby accelerating the extraction of the solid raw materials by the solvent;

[0030] In this embodiment: the waste discharge component 4 includes a fixed frame 401 arranged between the support legs 101, a support cylinder 402 arranged in the middle of the fixed frame 401, a telescopic cylinder 403 installed in the middle of the support cylinder 402, a shielding cylinder 404 installed at the top telescopic end of the telescopic cylinder 403, and the top of the shielding cylinder 404 is fixed by pressing the center of the filter bag 5 with a fixing block 405; the fixing block 405 is conical and made of 304 stainless steel; both the support cylinder 402 and the shielding cylinder 404 are cylindrical without a bottom. When telescopic, the shielding cylinder 404 completely covers the support cylinder 402, and the support cylinder 402 completely covers the telescopic cylinder 403; When the telescopic cylinder 403 is in the retracted state, the support cylinder 402 supports the telescopic cylinder 403 to pull the filter bag 5 into an inverted cone shape through the shielding cylinder 404. After the extract is filtered through the filter bag 5, it flows into the collection bucket 7 below (the fixing block 405 prevents the extract from accumulating at the bottom of the filter bag 5). The waste residue is left in the filter bag 5. After the extraction is completed, the collection bucket 7 is removed. The fixing frame 401 supports the telescopic cylinder 403 to extend through the support cylinder 402, pushing the shielding cylinder 404 to push the center of the filter bag 5 to bulge, forming a positive cone shape. At this time, rinsing the filter bag 5 with clean water will allow the waste residue to flow down the filter bag 5 and be discharged.

[0031] Working principle: Solvent and solid raw materials are fed into the cylinder 201 from the feed hopper 302. The cylinder cover 301 supports the second motor 204 to drive the stirring rod 304 to rotate, accelerating the extraction of the solid raw materials by the solvent. After completion, the outlet valve 206 is opened, and the extract and waste residue in the cylinder 201 are discharged from the outlet pipe 205 and flow into the filter bag 5 pressed by the fixing ring 6 on the lower support plate 103. At this time, the telescopic cylinder 403 is in the retracted state. The support cylinder 402 supports the telescopic cylinder 403 to pull the filter bag 5 into an inverted cone shape through the shielding cylinder 404. After being filtered by the filter bag 5, the extract flows into the collection bucket 7 below. The fixing block 405 prevents the extract from accumulating at the bottom of the filter bag 5, while the waste residue is left inside the filter bag 5. At the same time, the upper support plate 102 supports the first motor 303 to drive the active gear 203 to mesh with the passive gear ring 202, thereby rotating the box cylinder 201. This causes the liquid outlet pipe 205 to carry the waste residue circumferentially into the filter bag 5, preventing blockage and accelerating filtration. After extraction is completed, the collection bucket 7 is removed, and the fixing frame 401 supports the extension of the telescopic cylinder 403 through the support cylinder 402. This pushes the shielding cylinder 404 to push the center of the filter bag 5 to bulge, forming a positive cone shape. At this time, rinsing the filter bag 5 with clean water will allow the waste residue to flow down the filter bag 5 and be discharged.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
