Description

Technical Field

[0001] The invention relates to the technical field of chemical waste residue recovery equipment, and in particular to an environmentally friendly chemical waste residue recovery device. Background Art

[0002] Chemical waste residues often contain a large amount of harmful substances. If these substances enter the environment, they will be transmitted and spread along the food chain, posing a long-term threat to the ecosystem and human health. Environmentally friendly recycling devices can effectively remove or reduce the content of harmful substances in waste residues by treating them, preventing them from being released and spread in the natural environment, thereby protecting ecological and environmental elements such as soil, water sources and air. The recycling of chemical waste residues plays many important roles, covering multiple fields such as resource recycling, environmental protection and economic efficiency improvement. The specific steps involved mainly include coarse filtration or initial filtration of waste residues in chemical wastewater, as well as subsequent screening, cleaning and recycling of waste residues. As the beginning of the entire process of chemical waste residue recycling, the initial collection and extraction of chemical waste residues is very important, which is directly related to the quality of the recycling effect.

[0003] When recycling chemical waste residues, the first step of extracting waste residues is rough extraction of waste residues, that is, most of the waste residues are roughly extracted first, and the remaining wastewater is selected according to the type of waste residues for further fine extraction or directly enters the chemical treatment link. When rough extraction of chemical waste residues is carried out, chemical wastewater is generally directly passed into a filtering device, and waste residues are obtained after filtering through multiple layers of filter screens, and then the waste residues are recycled. However, because chemical wastewater contains a variety of chemical substances, in the process of converging flow, there are not only debris and slag, but also flocculent precipitation and other floccules. These floccules contain a large amount of waste residues, and with the passage of time, due to the relative stability of wastewater flow, the floccules gradually increase and lengthen, forming a variety of strip-shaped soft mixtures, which wrap the waste residues layer by layer, and when filtering, they will also cover the corresponding filter plates layer by layer, which can easily cover the filter plates or dense filter screens, resulting in clogging of the filter elements and obstruction of waste residue extraction. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide an environmentally friendly chemical waste recovery device, which adopts a dynamic circulation fishing working mechanism to solve the problem of blockage that is easy to occur during the rough extraction of chemical waste during the extraction process of chemical waste.

[0005] The present invention is achieved through the following technical solutions:

[0006] An environmental protection recycling device for chemical industrial waste residues, comprising a waste water tank for storing chemical industrial waste water. The accommodation cavity of the waste water tank is a cylindrical cavity horizontally arranged axially. An inlet cage is eccentrically arranged above the center in the accommodation cavity and is fixed in the accommodation cavity. The inlet cage is a cylindrical barrel with closed ends. The side surface of the inlet cage has a plurality of water permeable slits. The rear end of the inlet cage is connected with an inlet pipeline, and a gear assembly is installed at the front end. One transmission gear on the gear assembly is eccentrically arranged with respect to the accommodation cavity, and an installation frame is fixed on the gear shaft of the transmission gear. A scraping plate and a fishing frame are installed in the installation frame. The fishing frame is integrally formed by connecting a plurality of link assemblies in the shape of parallelograms in series by hinge connections. One end of the fishing frame is connected to one side of the scraping plate, and the other end is connected to one side of the installation frame close to the inner wall of the accommodation cavity. The scraping plate is connected to one end of an elastic telescopic rod, and the elastic telescopic rod is installed on the installation frame, so that under the pulling force of the elastic telescopic rod, the scraping plate always makes sliding contact with the cylindrical surface of the inlet cage. A slag discharge hole is opened at the top end of the accommodation cavity. A blocking plate is installed on one side of the slag discharge hole in a vertically sliding fit manner. The bottom end of the blocking plate has a horizontally extending bearing plate. When the fishing frame rotates from the lowest point to the highest point driven by the transmission gear, the scraping plate continuously compresses the fishing frame. When the fishing frame moves to near the slag discharge hole, the waste residues between the fishing frame and the blocking plate are extruded together, and when the blocking plate moves vertically upward, the waste residues can be taken out of the waste water tank upward.

[0007] Further, the gear assembly further includes a driving gear coaxially and rotatably installed at the front end of the inlet cage, and the driving gear meshes with the transmission gear.

[0008] Further, the installation frame is in a Π-shaped frame structure. One side of the inlet cage is located within the opening of the installation frame, and the frame beam on one side of the installation frame is fixed on the gear shaft. On the two opposite side walls within the opening of the installation frame, a rectangular strip groove is respectively opened along their lengths. The two ends of the scraping plate are slidably installed in the rectangular strip grooves, and the left and right opposite hinge ends of the link assembly are slidably and fittingly located within the rectangular strip grooves, so that when the transmission gear rotates, the fishing frame is compressed along the extending direction of the rectangular strip grooves.

[0009] Further, the elastic telescopic rod includes an inner inserted rod, an outer sleeve tube and a tension spring. A limit sliding block is integrally formed at the end of the scraping plate, and the limit sliding block is in a linear sliding fit within the rectangular strip groove. An annular groove with an arc-shaped groove bottom is formed in the middle of the limit sliding block. A collar is arranged within the annular groove, and the collar is fixed on the inner inserted rod. After the inner inserted rod is coaxially inserted into the outer sleeve tube, it is connected to the tension spring within the outer sleeve tube, and the outer sleeve tube is fixedly connected and penetrates through the frame beam.

[0010] Furthermore, on one side of the orifice of the slag discharge hole, there is a first baffle, and on the other side, there is a second baffle. The first baffle is in sliding fit with the intercepting plate. A sliding column is fixed on the back of the first baffle, and the sliding column is vertically and slidably installed in the first baffle. A hydraulic rod is fixed on the first baffle, and the hydraulic rod is connected to one end of the sliding column exposed on its surface; at the bottom end of the second baffle, there is fixed an arc-shaped plate, which is concentric with the accommodating cavity, and is slidably installed in the cavity wall of the accommodating cavity and is connected to an elastic element in the cavity wall. When the installation frame moves to the bottom end of the second baffle together with the fishing frame, the installation frame drives the second baffle and the arc-shaped plate to rotate together, and when the installation frame crosses the slag discharge hole, the second baffle and the arc-shaped plate are separated from the synchronous movement state with the installation frame due to contact with the intercepting plate.

[0011] Furthermore, the elastic element is a silica gel elastic cord or a spring with an arc-shaped axis.

[0012] Furthermore, inside the bottom end of the second baffle and at the end of the installation frame in sliding contact with the accommodating cavity, there is respectively provided a magnet. When the two magnets face each other, the second baffle and the installation frame are adsorbed and fixed as a whole.

[0013] Furthermore, one end of a slag discharge plate is fixed to the top end of the second baffle. The slag discharge plate is an arc-shaped shell concentric with the accommodating cavity. The other end of the slag discharge plate bends downward and extends toward the side away from the slag discharge hole to discharge the waste residue downward into a specified container; a horizontal plate is fixed to the top end of the first baffle, and the horizontal plate completely blocks the upper part of the orifice of the slag discharge hole and extends above one end of the slag discharge plate.

[0014] Furthermore, an isolation cylinder is rotatably fitted at at least one end of the water inlet cage. The isolation cylinder is coaxially arranged with the transmission gear. The two end faces of the isolation cylinder are in dynamic sealing contact with the water inlet cage and the accommodating cavity respectively; the installation frame slidably passes through the cylinder wall of the isolation cylinder along the radial direction of the isolation cylinder.

[0015] Furthermore, the bearing plate is a horizontally arranged elastic telescopic plate. The free end of the elastic telescopic plate can contact the frame surface of the fishing frame, and the elastic telescopic plate can freely vertically pass through the slag discharge hole.

[0016] The beneficial effects of the present invention are as follows:

[0017] In this chemical waste residue environmental protection recycling device, a large amount of waste residue in the wastewater will gradually accumulate at the bottom of the water inlet cage, which is conducive to centralized extraction. The secondary wastewater passing through the water inlet cage is stirred again by a fishing frame composed of several connecting rod assemblies in a quadrilateral shape to fish out some waste residue. Moreover, since a traditional filter plate is not used, blockage is hardly caused. After several rotations, a large amount of waste residue in the wastewater, including flocculants, can be successively extracted. In addition, due to the dynamic rotation of the fishing frame, the water in the wastewater tank is always in an unstable state, which greatly slows down the layer-by-layer covering of the flocculants on the surface of the waste residue, making it easier to fish out the waste residue. Specifically, the wastewater first enters the water inlet cage for filtration, filtering some waste residue in the water inlet cage. The remaining wastewater flows into the wastewater tank and can freely flow back into the water inlet cage for secondary rough filtration. Moreover, due to the intermittent rotation of the fishing frame, the wastewater in the water inlet cage can always be in a flowing state, unlike the traditional filter plate, which gradually and stably settles with the flow of water and then gradually covers the waste residue, forming a thick layer that cannot disperse and directly blocking the filter plate.

[0018] By arranging a water inlet cage eccentrically relative to the wastewater tank and a fishing frame rotating eccentrically relative to the water inlet cage, while automatically scraping and cleaning the surface of the water inlet cage, the fishing frame is adaptively shortened, and the void density of the fishing frame is increased to automatically adapt to the gradually smaller accommodation space in the second half of a rotation cycle, and to prepare for centrally squeezing the fished waste residue at the slag discharge hole. Near the slag discharge hole, the fishing frame can be compressed to the limit, forming a very narrow parallelogram-shaped void. At the same time, it cooperates with a special intercepting plate to better squeeze the waste residue, and then the waste residue is automatically extracted from the slag discharge hole to prepare for further subsequent cleaning of the waste residue.

[0019] Other advantages, objectives, and features of the present invention will be described to some extent in the subsequent specification, and to some extent, they will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following specification. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0033] Therefore, the detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0034] It should be noted that like reference numerals and letters refer to like items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] Please refer to Figure 1 , the present invention provides a technical solution: an environmental protection recycling device for chemical industrial waste residue, including a waste water tank 1 for storing chemical industrial waste water. The accommodating cavity 5 of this waste water tank 1 is a cylindrical cavity horizontally arranged axially, that is, this waste water tank 1 is installed horizontally. A drain pipe 3 is installed on the bottom side wall. After discharging slag multiple times, according to needs, the drain pipe 3 is manually opened to discharge the waste water. Specifically, an inlet cage 2 is eccentrically arranged above the center in the accommodating cavity 5. The inlet cage 2 is fixed in the accommodating cavity 5, and this inlet cage 2 is a cylindrical tube with both ends closed. As Figure 9 shown, there are several water permeable slits on the side surface of this inlet cage 2. This water permeable slit is different from a conventional filter plate. While it is relatively long and narrow itself, its width is relatively wide. General flocs and the like can pass through freely, and because of the flexibility of the flocs themselves, they can flow through the above-mentioned water permeable slits adaptively, and then some large-sized or harder waste residues are left in the inlet cage 2 so that the inlet cage 2 can be taken out and cleared in time. In this embodiment, the waste water enters the inlet cage 2 through the waste water cage, and a water inlet pipe is connected to the rear end of the inlet cage 2. Large scraps and the like are left in the inlet cage 2. During specific manufacturing, a gear assembly is installed at the front end of the inlet cage 2. A driving gear 4 on this gear assembly is eccentrically arranged with the accommodating cavity 5. As a specific embodiment, as Figure 1 , this gear assembly further includes a driving gear 8 coaxially and rotatably installed at the front end of the inlet cage 2. The driving gear 8 meshes with the driving gear 4 to drive the fishing frame 13 to rotate. As Figures 2 - 3 , a mounting frame 12 is fixed on the gear shaft 9 of the driving gear 4. A scraping plate 11 and a fishing frame 13 are installed in this mounting frame 12. The fishing frame 13 is used to pick up some waste residues in the waste water, such as some flexible wastes that can pass through the inlet cage 2, or the flocs formed by chemical reactions in the waste water. Even a special filter mesh (which will be further introduced later) can be laid on the fishing frame 13 according to needs. As a specific structural design, as Figures 4 - 5 shown, this fishing frame 13 is formed by connecting a plurality of link assemblies with parallelogram structures in series by hinge connections. One end of the fishing frame 13 is connected to one side of the scraping plate 11, and the other end is connected to one side of the mounting frame 12 close to the inner wall of the accommodating cavity 5 so that when the scraping plate 11 moves, the fishing frame 13 can be stretched or compressed. During installation, the scraping plate 11 is connected to one end of an elastic telescopic rod 10. The elastic telescopic rod 10 is installed on the mounting frame 12 so that the scraping plate 11 is always in sliding contact with the cylindrical surface of the inlet cage 2 under the pulling force of the elastic telescopic rod 10, so as to scrape off the flocs and the like accumulated around the inlet cage 2 during rotation.Figure 1 , in this embodiment, a slag discharge hole 6 is also provided at the top of the accommodation cavity 5. This slag discharge hole 6 is mainly used to take out some waste residues. On one side of this slag discharge hole 6, an intercepting plate 7 is vertically and slidably installed. The bottom end of the intercepting plate 7 has a horizontally extending bearing plate. This intercepting plate 7 can be a solid plate or a hollow filter plate. During use, when the fishing frame 13 rotates from the lowest point to the highest point under the drive of the transmission gear 4, for example, rotates counterclockwise, the scraper 11 continuously compresses the fishing frame 13 to adapt to the continuously decreasing flow channel volume between the accommodation cavity 5 and the water inlet cage 2, forming a continuously decreasing water-permeable area (i.e., the gap in the shape of a parallelogram). When the fishing frame 13 moves near the slag discharge hole 6, it will squeeze the waste residues between it and the intercepting plate 7 together. After compressing the waste residues, the intercepting plate 7 moves vertically upward, and most of the waste residues can be taken out of the wastewater tank 1 upward, and then collected and discharged for subsequent recycling. It should be noted that when performing the rough extraction of chemical industrial waste residues, the rotation speed of the above-mentioned fishing frame is selected according to the adaptability of specific chemical wastewater. The principle is that during the intermittent rotation process, try to let the flocs and waste residues be fished out by the fishing frame. This specification appendix Figure 4 and Figure 6 To clearly show the structure, the fishing frame is overly stretched and expanded for display, and the shown parallelogram is relatively thick. In actual production, it is best to present a narrow and long narrow-hole shape when the fishing frame is in the lowest position, that is, the diagonal in the left-right direction is much larger than the diagonal in the vertical direction; if necessary, a mesh cloth can also be laid in the parallelogram area of each link assembly of the fishing frame, but it is not the traditional fine-mesh filter screen with dense pores. Instead, the holes on the mesh cloth are long strip-shaped holes with a large width, just like the water-permeable slits of the water inlet cage 2, to improve the fishing efficiency.

[0036] In this embodiment, as Figure 4 , the installation frame 12 has a Π-shaped frame structure. One side of the water inlet cage 2 is located inside the opening of the installation frame 12, and as Figure 7 shown, the frame beam 1201 on one side of the installation frame 12 is fixed on the gear shaft 9 to rotate synchronously with the rotation of the transmission gear 4. On the two opposite side walls inside the opening of the installation frame 12, as Figure 5 , a rectangular strip groove is respectively opened along their lengths. The two ends of the scraper 11 are slidably installed in the rectangular strip groove to guide the telescopic movement of the fishing frame 13, that is, the two relatively hinged ends of the link assembly are slidably fitted inside the rectangular strip groove, so that when the transmission gear 4 rotates, the fishing frame 13 is compressed along the extension direction of the rectangular strip groove to adapt to the continuously decreasing volume.

[0037] In this embodiment, as Figure 3, the elastic telescopic rod 10 adopted includes an inner inserted rod 1002, an outer sleeve 1001 and a tension spring. The end of the scraping plate 11 integrally has a limit slider 24, and the limit slider 24 is linearly slidably fitted in the rectangular strip groove to guide the sliding of the scraping plate 11. The middle of the limit slider 24 has an annular groove with an arc-shaped bottom, and a collar 1003 is arranged in the annular groove. The collar 1003 is fixed on the inner inserted rod 1002. After the inner inserted rod 1002 is coaxially inserted into the outer sleeve 1001, it is connected to the tension spring in the outer sleeve. The outer sleeve 1001 is fixedly connected and penetrates through the frame beam 1201, so as to well maintain the sliding contact between the scraping plate 11 and the water inlet cage 2 during the rotation of the scraping plate 11 around the outer wall of the water inlet cage 2, and preferably scrape out the waste residue, floccules, etc. on the surface of the water inlet cage 2.

[0038] In order to better discharge the slag, as Figure 1 , on one side of the orifice of the slag discharge hole 6 mentioned in the previous text, there is a first baffle 15. The first baffle 15 can be integrally formed with the waste water tank 1. On the other side of the slag discharge hole 6, there is a second baffle 17. The area between the two baffles can allow the waste residue to move up and be lifted out. More specifically, the first baffle 15 is vertically slidably fitted with the intercepting plate 7. A sliding column 16 is fixed on the back of the first baffle 15. The sliding column 16 is vertically slidably installed in the first baffle 15. A hydraulic rod 14 is fixed on the first baffle 15. The hydraulic rod 14 is connected to the end of the sliding column 16 exposed on its surface. When the hydraulic rod 14 contracts, it can drive the intercepting plate 7 to move vertically upward, and then lift out part of the waste residue. In addition, an arc-shaped plate 18 can be fixed at the bottom end of the second baffle 17. The arc-shaped plate 18 is concentric with the accommodating cavity 5, and is slidably installed in the cavity wall of the accommodating cavity 5 and is connected to an elastic element 19 in the cavity wall. This elastic element 19 can be a silicone elastic rope or a spring with an arc-shaped axis. The elastic element 19 maintains the arc-shaped plate 18 in a Figure 1In specific use, when the mounting frame 12 moves with the fishing frame to the bottom end of the second baffle 17, the mounting frame 12 rotates with the second baffle 17 and the arc plate 18, that is, the mounting frame 12, the fishing frame 13, the second baffle 17 and the arc plate 18 become a whole and move synchronously, and when the mounting frame 12 passes over the slag discharge hole 6, the second baffle 17 and the arc plate 18 cannot continue to move synchronously because of the contact with the interception plate 7, and then automatically break away from the synchronous movement state with the mounting frame 12, and the second baffle 17 and the arc plate 18 are reset under the action of the elastic element 19. During this process, the main purpose is to squeeze the waste slag picked up by the fishing frame 13 so that the fishing frame 13 contacts the intercepting plate 7, specifically, when it contacts the supporting plate of the intercepting plate 7, the waste slag is fully squeezed, which is convenient for concentrated removal from the slag discharge hole 6. The squeezing effect and slag discharge channel adaptively formed by the two baffles are conducive to the concentrated discharge of more waste slag; in addition, the channel formed by the two baffles can prevent waste water from splashing out of the slag discharge hole 6 when squeezing the waste slag, which is equivalent to deepening the depth of the slag discharge hole 6. When the aforementioned supporting plate is manufactured, it can be a horizontally arranged elastic retractable plate 22, the free end of which can contact the frame surface of the fishing frame, and the elastic retractable plate 22 can freely shuttle vertically in the slag discharge hole 6, so that after the waste slag is lifted up, it can freely fall down and reset. Figure 1 As shown, as the capture frame continues to rotate, the waste slag is further squeezed, and the supporting plate shrinks adaptively. When the intercepting plate 7 moves upward, the supporting plate scrapes off the accumulated waste slag and other residues on the surface of the capture frame, which is equivalent to cleaning it. When the supporting plate moves to the outside of the slag discharge hole 6 and needs to retreat, it is squeezed and contacted with the second baffle plate 17, and then enters into the slag discharge hole 6. Regardless of entering or exiting, it can be squeezed and contacted with the capture frame and the second baffle plate 17 to fully remove the waste slag.

[0039] In this embodiment, in order to realize the rotation of the mounting frame 12 with the second baffle 17 and the arc plate 18, a magnet (not shown in the figure) is respectively provided inside the bottom end of the second baffle 17 and inside the end where the mounting frame 12 and the accommodating chamber 5 are in sliding contact. When the two magnets are facing each other, they have a large magnetic attraction force, thereby adsorbing and fixing the second baffle 17 and the mounting frame 12 as a whole, so that the mounting frame 12, the fishing rack 13, the second baffle 17 and the arc plate 18 become a whole and move synchronously until they are separated from the second baffle 17 and the arc plate 18.

[0040] In this embodiment, Figure 1, one end of a slag discharge plate 20 is fixed to the top of the second baffle 17. The slag discharge plate 20 is an arc-shaped shell concentric with the accommodating cavity 5. The other end of the slag discharge plate 20 bends downward and extends toward the side away from the slag discharge hole 6 to discharge the waste slag downward into a designated container. On the front and back sides of the slag discharge plate 20, a retaining plate can be fixed respectively to form an arc-shaped slide structure, so as to better convey the waste slag to a designated position or container. A cross plate 21 can also be horizontally fixed to the top of the first baffle 15. The cross plate 21 completely shields the upper part of the orifice of the slag discharge hole 6 and extends above one end of the slag discharge plate 20, which is beneficial to the output of the waste slag.

[0041] In the recovery device in the above embodiments, in order to minimize the pollution to the gear assembly and affect the transmission, it can be like Figures 9 - 11 , a separating cylinder 23 is rotatably fitted at at least one end of the water inlet cage 2. The separating cylinder 23 is a circular cylindrical structure. The separating cylinder 23 is coaxially arranged with the transmission gear 4. The two end faces of the separating cylinder 23 are in dynamic sealing contact with the water inlet cage 2 and the accommodating cavity 5 respectively to enclose the gear assembly. The mounting frame 12 passes through the cylinder wall of the separating cylinder 23 in a sliding fit along the radial direction of the separating cylinder 23. In the above design structure, because one of the frame beams 1201 of the mounting frame 12 is fixed, the purpose of the fishing frame and the gear shaft 9 rotating together can be achieved. Therefore, only one transmission gear 4 can be provided. Therefore, for the aforementioned water inlet cage 2, it is required that a separating cylinder 23 is rotatably fitted at at least one end; in practice, if space permits, transmission gears 4 can be arranged on the front and back end faces of the water inlet cage 2, that is, symmetrically arranged front and back. Then, at this time, two separating cylinders 23 are required, that is, as Figure 11 shown, to protect the two groups of gear assemblies.

[0042] In the above description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "one side" and "the other side" is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present invention is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. In addition, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0043] In addition, terms such as "the same" do not mean that the components are required to be absolutely the same, but there can be slight differences. The term "vertical" only means that the positional relationship between components is relatively more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly inclined.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
