Description

Technical Field

[0001] This utility model relates to the field of technical fields, and more specifically, to a waste residue separation device for chemical machinery. Background Technology

[0002] In chemical production processes, the mixtures generated after reactions (including liquid media and solid waste) require solid-liquid separation. On the one hand, the separated liquid media (such as reaction solvents and process water) can be recycled back to the production line, reducing raw material consumption and production costs. On the other hand, the separated solid waste must meet environmental emission or subsequent disposal standards to avoid direct discharge that could pollute the environment, while also reducing the risk of secondary pollution from residual liquid in the waste. Therefore, waste separation is a crucial step in ensuring resource recovery and environmental compliance in chemical production processes.

[0003] In the current separation of chemical waste, horizontal screw discharge sedimentation centrifuges are widely used. Their core structure includes a horizontally placed cylindrical drum, a screw conveyor coaxially mounted inside the drum, a main motor driving the drum, and a differential gear (linked to the main motor) driving the screw conveyor. The mixed material enters from the middle of the drum through the feed pipe. Under the centrifugal force generated by the high-speed rotation of the drum, the solid waste settles to the inner wall of the drum. The screw conveyor pushes the waste towards the solid phase outlet at the conical end of the drum at a speed slightly lower than that of the drum. The clarified liquid is discharged from the liquid phase outlet at the cylindrical end of the drum, achieving continuous separation.

[0004] Certain problems arise during equipment operation. On the one hand, unreliable sealing can easily occur, leading to leakage or mixing of substances that should be effectively separated. This affects the accuracy of the separation results and may also have adverse effects on the surrounding environment. On the other hand, residual substances can easily accumulate in the slag discharge area inside the equipment. The continuous accumulation of these residual substances reduces the overall separation efficiency and may also interfere with subsequent separation operations, affecting the continuous and stable operation of the equipment. Therefore, we urgently need a waste residue separation device for chemical machinery to solve the above problems. Utility Model Content

[0005] One objective of this invention is to provide a new technical solution for a waste residue separation device for chemical machinery. This solution constructs a reliable seal by using an arc-shaped sleeve, a flip-up end cover, a screw slide, and a U-shaped plate seal. Combined with multiple sets of vertical scrapers, springs, and protrusions to clean the residue at the discharge point, and with zoned discharge, it solves the problems of unreliable sealing and residue accumulation, improves separation accuracy and efficiency, and ensures stable operation of the equipment.

[0006] According to a first aspect of this utility model, a waste residue separation device for chemical machinery is provided, including a support frame for supporting the equipment, a rotating drum rotatably connected to the support frame via a drive component, and a screw conveyor disposed inside the rotating drum, with the screw conveyor end fixedly mounted on the support frame via the drive component. The device further includes: an arc-shaped sleeve fixedly mounted on the support frame for sealing, an arc-shaped end cap for sealing being flipped on the support frame, which is locked in place by a sealing component when the arc-shaped end cap engages with the arc-shaped sleeve; and a vertical frame fixedly mounted at the slag discharge port of the rotating drum, the vertical frame being provided with a cleaning component for cleaning adhering materials.

[0007] Optionally, the seal includes rectangular plates symmetrically mounted on a bracket, one of which has a screw rotatably connected inside it, and the other set of rectangular plates has a guide rod fixedly connected to it. A sliding rod is provided between the two sets of rectangular plates, one end of which is threadedly connected to the screw and the other end of which is slidably connected to the guide rod. When the screw rotates, the sliding rod moves closer to or away from the arc-shaped sleeve.

[0008] Optionally, U-shaped plates are symmetrically installed on the slide rod, and anti-slip pads are fixedly installed on the inner wall of the U-shaped plates. When the arc-shaped end cap and the arc-shaped sleeve are fastened, the anti-slip pads inside the U-shaped plates clamp the connection and form a fastening area.

[0009] Optionally, the number of the uprights is in multiple groups, and the multiple groups of uprights are arranged equidistantly in a ring around the axis of the drum.

[0010] Optionally, the cleaning component includes a sliding groove formed on the upright for sliding, a straight rod fixedly connected in the sliding groove, and a scraper for cleaning the inner wall slidably connected in the sliding groove and on the straight rod.

[0011] Optionally, a spring is sleeved inside the sliding groove and on the straight rod, with both ends of the spring connected to the scraper and the inner wall of the sliding groove, respectively.

[0012] Optionally, both the arc-shaped sleeve and the arc-shaped end cap are provided with protrusions at equal intervals along their arc. The protrusions are right-angled trapezoids. When the drum rotates, the scraper abuts against the inner wall of the arc-shaped sleeve and the protrusions along the arc-shaped sleeve and the arc-shaped end cap.

[0013] Optionally, the drum is fixedly connected to a feed pipe for feeding, the arc-shaped sleeve is provided with a slag discharge pipe corresponding to the scraper, and the arc-shaped sleeve is provided with a liquid discharge port away from the slag discharge pipe.

[0014] 1. According to one embodiment of this disclosure, the waste residue separation device for chemical machinery constructs a basic sealed space by fastening an arc-shaped sleeve with a reversible arc-shaped end cap. Then, by using a sealing structure of "screw driving slide bar sliding, U-shaped plate clamping tightly sealing the cover, and anti-slip pad filling the tiny gaps", a highly stable seal is achieved during the separation process, effectively preventing leakage or mixing of liquid and waste residue. This ensures the purity of the separated products and avoids pollution of the surrounding environment by leaked substances, thus reducing additional environmental remediation costs.

[0015] 2. According to one embodiment of this disclosure, the waste residue separation device for chemical machinery drives the scraper to rotate synchronously with the drum through 3-6 sets of annular equidistant vertical frames. With the help of springs, the scraper is kept in continuous contact with the inner wall of the slag discharge point. The protrusions drive the scraper to move slightly to remove stubborn residues. At the same time, the device adopts a partitioned discharge design of "liquid discharge port away from slag discharge port and slag discharge port corresponding to scraper", which realizes real-time and efficient cleaning of residues at the slag discharge point and no cross-discharge of liquid and slag. This not only avoids the decrease in separation efficiency caused by residue accumulation, but also reduces the frequency of equipment maintenance caused by cleaning residues and extends the stable operation cycle of the equipment.

[0020] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0021] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0022] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0023] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0024] like Figure 1-4 As shown, a waste residue separation device for chemical machinery includes a support frame 1 for supporting the equipment. A rotating drum 2 is rotatably connected to the support frame 1 via a drive component, and a screw conveyor 3 is installed inside the rotating drum 2. The screw conveyor 3 is fixedly installed on the support frame 1 via a drive component.

[0025] Here, bracket 1 serves as the support carrier for the entire equipment, precisely positioning and installing all components such as drum 2 and arc sleeve 4, ensuring that the relative positions of each structure are fixed, avoiding misalignment of the sealing surface and deviation of the scraper 15 from the inner wall due to equipment shaking, and providing a fixing point for the drive components to ensure that drum 2 and screw conveyor 3 rotate synchronously, reducing mechanical wear.

[0026] Furthermore, the drum 2 is driven to rotate by a drive component, using centrifugal force to separate the liquid and waste residue in the mixture to be separated. The liquid, due to its lower density, is closer to the inner wall, while the waste residue, due to its higher density, gathers in the center, making it the core carrier for achieving solid-liquid separation. It provides an installation foundation for the frame 6, drives the cleaning component to rotate synchronously with the drum 2, and allows the scraper 15 to follow the trajectory of the drum 2 to thoroughly clean the inner wall. At the same time, its rotation speed can be adjusted in conjunction with the screw conveyor 3 to adapt to materials with different viscosities and waste residue contents, improving the equipment's versatility.

[0027] Furthermore, the screw conveyor 3 is installed inside the drum 2 and is driven to rotate by the drive component. It pushes the waste residue that has been separated and gathered in the center toward the slag discharge port, preventing the waste residue from accumulating inside the drum 2 and ensuring that the separated waste residue is discharged in a timely manner. It forms a "separation-conveyance" synergy with the "centrifugal separation" of the drum 2, solving the problem of "waste residue retention after separation". The spacing of its screw blades can be designed to be gradual, with the spacing becoming smaller near the slag discharge port, which enhances the squeezing and dewatering effect on the waste residue, improves the separation accuracy, and reduces the amount of liquid carried by the waste residue.

[0028] It also includes an arc-shaped sleeve 4 fixedly installed on the bracket 1 for sealing. An arc-shaped end cap 5 for sealing is flipped on the bracket 1. When the arc-shaped end cap 5 is fastened to the arc-shaped sleeve 4, it is locked by a sealing element.

[0029] Here, the arc-shaped sleeve 4 and the arc-shaped end cap 5 form a complete sealed cavity, eliminating "open leakage". The arc-shaped sleeve 4 is fixed on the support 1, providing a closed space for the separation operation and preventing liquid splashing and waste residue scattering during the separation process; the arc-shaped end cap 5 is designed to be flipped, and when running, it will snap together with the arc-shaped sleeve 4 to form a complete sealed cavity, structurally blocking the "liquid and residue overflow" channel.

[0030] Furthermore, it takes into account ease of maintenance and reduces equipment repair costs. When it is necessary to clean the inside of the equipment, simply flip open the arc-shaped end cover 5 without disassembling the entire structure, reducing maintenance time; when fastening, it can quickly align the sealing surface, improving the efficiency of equipment start-up and shutdown.

[0031] The sealing element includes rectangular plates 7 symmetrically mounted on the bracket 1. One rectangular plate 7 is rotatably connected to a screw 8, and another set of rectangular plates 7 is fixedly connected to a guide rod 9. A slide rod 10 is provided between the two sets of rectangular plates 7. One end of the slide rod 10 is threadedly connected to the screw 8, and the other end of the slide rod 10 is slidably connected to the guide rod 9. When the screw 8 rotates, the slide rod 10 moves closer to or away from the arc-shaped sleeve 4. A U-shaped plate 11 is symmetrically mounted on the slide rod 10. An anti-slip pad 12 is fixedly installed on the inner wall of the U-shaped plate 11. When the arc-shaped end cap 5 is fastened to the arc-shaped sleeve 4, the anti-slip pad 12 inside the U-shaped plate 11 clamps the connection point and forms a fastening area.

[0032] Here, the screw 8 is threadedly connected to the slide bar 10. Rotating the screw 8 will drive the slide bar 10 to slide along the guide bar 9. Rotating the screw 8 clockwise will bring the slide bar 10 closer to the sealing surface, increasing the clamping force; rotating it counterclockwise will decrease the clamping force, avoiding problems caused by insufficient or excessive clamping force.

[0033] Furthermore, the guide rod 9 restricts the sliding direction of the slide rod 10, allowing it to move only in the horizontal direction. This prevents the slide rod 10 from shifting up and down or left and right during movement, ensuring that the U-shaped plate 11 on the slide rod 10 can be accurately aligned with the sealing surface and preventing "partial clamping failure".

[0034] Furthermore, the U-shaped plate 11 is symmetrically installed on the slide rod 10. Its "open wrap-around" structure can fit the connection between the arc-shaped sleeve 4 and the end cap. Compared with the flat clamping parts, the contact area is increased by more than 30%, avoiding "clamping point offset" caused by equipment vibration and forming a stable "fastening zone". The anti-slip pad 12 is made of oil-resistant and wear-resistant rubber material. On the one hand, it increases the friction with the sealing surface and prevents the U-shaped plate 11 from loosening when the equipment vibrates. On the other hand, it can fill the tiny gaps in the sealing surface, eliminate "micro-leakage", and further improve the sealing reliability.

[0035] The uprights 6 are fixedly installed at the slag discharge port of the rotating drum 2. There are multiple sets of uprights 6, and the multiple sets of uprights 6 are arranged in a ring at equal intervals around the axis of the rotating drum 2.

[0036] Here, the support frame 6 is installed in a ring at equal intervals with the axis of the drum 2 as the center. Usually, 3-6 sets are set. When the scraper 15 rotates with the drum 2, it can cover the entire range of the slag discharge area of ​​the arc sleeve 4 and the arc end cover 5, avoiding the problem of local residue accumulation caused by the single set of cleaning parts in the existing equipment.

[0037] Furthermore, the rigid support frame 6 ensures cleaning power. The frame 6 is made of stainless steel, which is high in strength and resistant to deformation. It can withstand the reaction force when the scraper 15 removes stubborn residue, preventing the scraper 15 from detaching from the inner wall due to deformation of the frame 6, thus ensuring long-term cleaning effectiveness.

[0038] The upright frame 6 is equipped with a cleaning component for cleaning attached materials. The cleaning component includes a sliding groove 13 opened on the upright frame 6 for sliding. A straight rod 14 is fixedly connected in the sliding groove 13. A scraper 15 for cleaning the inner wall is slidably connected in the sliding groove 13 and located on the straight rod 14. A spring 16 is sleeved in the sliding groove 13 and located on the straight rod 14. The two ends of the spring 16 are respectively connected to the scraper 15 and the inner wall of the sliding groove 13. The arc-shaped sleeve 4 and the arc-shaped end cap 5 are both provided with protrusions 17 at equal intervals along their arc. The protrusions 17 are right-angled trapezoids. When the drum 2 rotates, the scraper 15 abuts against the inner wall of the arc-shaped end cap 5 and the protrusions 17 along the arc-shaped sleeve 4.

[0039] Here, the sliding groove 13 is opened on the upright 6, and the straight rod 14 is fixed in the groove. When the scraper 15 slides along the straight rod 14, it can only move "closer to / away from the inner wall of the slag discharge point" to avoid the scraper 15 deviating and ensure that the scraper 15 is always aligned with the residual area of ​​the slag discharge point, so as not to waste cleaning force.

[0040] Furthermore, the scraper 15 is made of elastic alloy material, and its end can be slightly deformed according to the arc surface at the slag discharge point to fit tightly against the inner wall. Even if there are processing errors or slight wear at the slag discharge point, it can still scrape off the attached waste residue, thus improving the scraping rate.

[0041] Furthermore, the spring 16 is sleeved on the straight rod 14, with its two ends connected to the scraper 15 and the inner wall of the sliding groove 13, respectively. Its preload can always push the scraper 15 against the inner wall of the slag discharge area. Even if the scraper 15 is worn after the equipment has been running for a period of time, the spring 16 can still push the scraper 15 to fill the gap and maintain the fit, avoiding the increase of the cleaning gap at the slag discharge area due to wear. When the scraper 15 encounters hard residual clumps at the slag discharge area, the spring 16 can absorb the impact force through compression, avoiding the "fracture of scraper 15" and "deformation of straight rod 14" caused by hard contact between the scraper 15 and the clumps, reducing the frequency of component replacement and reducing maintenance costs.

[0042] It should be noted that the protrusions 17 are equidistantly distributed along the arc of the slag discharge point of the arc sleeve 4 and the arc end cap 5, forming a right-angled trapezoid. When the drum 2 drives the scraper 15 to rotate, the end of the scraper 15 will slide along the inclined surface of the protrusions 17. When it climbs up the inclined surface, the scraper 15 compresses the spring 16. When it slides down the inclined surface, the spring 16 returns to its original position, causing the scraper 15 to "move up and down slightly" at the slag discharge point. This allows for "repeated scraping" of stubborn residues that are prone to clumping at the slag discharge point. Compared with a fixed scraper 15, the cleaning efficiency of stubborn residues is improved.

[0043] Furthermore, the right-angled trapezoidal slope design, with an inclination angle of 30-45°, can guide the scraper 15 to slide smoothly without "jamming" and avoid increased load on the drum 2 and overload of the drive components due to jamming, ensuring that the cleaning at the slag discharge point and the conveying of waste slag are carried out simultaneously.

[0044] The drum 2 is fixedly connected to a feed pipe 18 for feeding. The arc-shaped sleeve 4 is provided with a slag discharge pipe 19 corresponding to the scraper 15, and a liquid discharge port 20 is provided on the arc-shaped sleeve 4 away from the slag discharge pipe 19.

[0045] In this invention, before startup, the arc-shaped end cap 5 on the support 1 is flipped and fastened to the fixed arc-shaped sleeve 4 to form a sealed cavity. Then, the screw 8 inside the rectangular plate 7 in the sealing component is rotated to drive the slide rod 10 to slide along the guide rod 9, so that the U-shaped plate 11 on the slide rod 10 clamps the cover tightly through the anti-slip pad 12, creating a leak-free environment. During operation, the mixture to be separated enters through the feed pipe 18 inside the drum 2. The drive unit drives the drum 2 to rotate at high speed, using centrifugal force to bring the liquid closer to the inner wall and the waste residue accumulation center. The screw conveyor 3 simultaneously pushes the waste residue to the slag discharge pipe 19. At the same time, 3-6 sets of annular equidistant uprights 6 at the slag discharge port of the drum 2 drive the scraper 15 to rotate with the drum 2. Under the action of spring 16, scraper 15 adheres to the inner wall of the slag discharge point. When it encounters the right-angled trapezoidal protrusion 17 on the arc sleeve 4 and the arc end cover 5, it generates micro-movement, which strengthens the scraping of stubborn residues. The sliding groove 13 and the straight rod 14 constrain the scraper 15 to perform directional cleaning. During the discharge stage, the separated liquid is discharged from the liquid outlet 20 on the arc sleeve 4 away from the slag discharge pipe 19. The waste residue and scraped residue are discharged through the slag discharge pipe 19 of the corresponding scraper 15 to avoid liquid and slag mixing. When stopping for maintenance, the screw 8 is rotated in the opposite direction to release the clamp, and the arc end cover 5 can be flipped open for convenient maintenance. The overall process solves the problems of unreliable sealing and residue accumulation at the slag discharge point through the synergy of various structures.
