Description

Technical Field

[0001] The utility model relates to the technical field of pyrolysis treatment of oily sludge, and particularly relates to a mechanical material cleaning device for the bottom and side walls of a silo. Background Art

[0002] Oily sludge belongs to the "National List of Hazardous Wastes" and is an oily solid waste generated during oil exploration, transportation, refining, and oily sewage treatment. Its composition is very complex, containing a large amount of aged crude oil, solid suspended matter, bacterial substances and other solid wastes, and crude oil is the main component. The characteristics of oily sludge: generally, the oil content of oily sludge is about 10%-50%, and the water content is about 40%-90%. The solid-phase particles of the sludge are fine, and the density difference between oil and water is small, resulting in high viscosity of the oily sludge, difficult sedimentation, and poor dehydration effect. The current oily sludge treatment technologies mainly include pyrolysis, conditioning centrifugal separation, solidification treatment, incineration, solvent extraction, hot alkali water washing, etc. Among them, pyrolysis is to indirectly heat the oily sludge by a heat source under anaerobic environmental conditions, and the organic components in the oily sludge volatilize, and then through subsequent gas condensation, collection, and recovery to achieve resource utilization.

[0003] The problems existing in the prior art are that in the incineration and pyrolysis processes, the water content and oil content of the carbon black and oily sludge waste gas materials are relatively high, and it is easy to stick to the wall in the hopper of the incineration and pyrolysis processes, affecting the feeding, and even causing material blockage.

[0004] In the prior art, one is to use an aeration valve to pneumatically clean the oily sludge adhering to the silo. However, the problem with this method is that the sticky material on the wall cannot be completely scraped clean by the airflow output by the aeration valve, there is a lot of residue on the inner wall of the silo, the cleaning effect is not stable, and the output airflow will cause pressure fluctuations in the downstream incinerator, affecting safe production.

[0005] In the prior art, the second is to use a spiral body to clean the material. However, due to the characteristics of the spiral body structure, there are cleaning dead spots.

[0006] Moreover, the blind spot existing in the prior art is that when the sticky material on the inner wall of the silo is cleaned off, it is easy to form a blockage at the silo discharge port.

[0007] Therefore, the effect of the prior art solutions in treating the sticky material on the inner wall of the silo is not ideal, and it is necessary to improve the design to achieve the purpose of fully cleaning the sticky material on the inner wall of the silo, avoiding dead corners and residues, avoiding affecting the subsequent process, and making a linkage design for the silo discharge port to avoid the blocked discharge port caused by the cleaned sticky material. Content of the Utility Model

[0008] In order to solve the above technical deficiencies, the utility model provides a mechanical material cleaning device for the bottom and side walls of a silo.

[0009] Technical solution of the utility model: A mechanical material cleaning device for the bottom and side walls of a silo, comprising a silo, a scraping frame, and a first driving mechanism. The silo includes a bottom slope, two side wall surfaces located on both sides of the bottom slope, and a discharge port, which is connected to the lowest point of the bottom slope.

[0010] The scraping frame includes a bottom frame, a first side frame, and a second side frame. The contour of the bottom frame is adapted to the contour of the bottom slope and is arranged to make a sliding fit on the bottom slope. The first and second side frames are respectively attached to the two side wall surfaces and are both connected to the bottom frame.

[0011] The first driving mechanism is linked and cooperated with the bottom frame to drive the bottom frame to make a reciprocating motion in the direction close to or away from the discharge port, driving the first and second side frames to scrape the sticky materials on the bottom slope and the side wall surfaces and push them toward the discharge port side.

[0012] Adopting the above technical solution, as shown in the accompanying drawings of the specification Figure 1 shown, the silo is in a hopper shape (or square). After the carbon black and oily sludge waste gas materials enter the silo, they mainly slide down from the bottom slope to the discharge port. The bottom slope and the two side wall surfaces on both sides are the main surfaces in contact with the materials and are also the main inner walls where the materials adhere. The inner wall opposite to the bottom slope is vertically arranged. In another embodiment, this inner wall can also be set as a slope, and a corresponding set of scraping frames and driving mechanisms can be set.

[0013] A reciprocating scraping frame is set. The bottom frame, the first and second side frames are used to scrape the bottom slope and the two side wall surfaces, so that the materials sticking to the inner wall are scraped off and are pushed into the discharge port along with the reciprocating push of the scraping frame toward the discharge port side.

[0014] Further setting of the utility model: A number of hollow slots are provided on the bottom frame. The hollow slots are provided with acute edges relative to the edge of the bottom slope. A first hinge seat is provided on the bottom frame.

[0015] A first connecting groove penetrating the silo is provided at the position of the bottom slope corresponding to the first hinge seat and the stroke length.

[0016] The first driving mechanism includes a cylinder, a main shaft, an intermediate swing arm, a side swing arm, and a connecting rod. On the outer surface of the silo at the first connection groove, a first bearing seat is provided. The main shaft is arranged on the first bearing seat for circumferential rotational cooperation. The main shaft is axially fixed and circumferentially synchronously rotationally connected to the intermediate swing arm and the side swing arm respectively. The side swing arm extends through the first connection groove into the silo. The two ends of the connecting rod are respectively hinge-connected to the first hinge seat and the side swing arm. The cylinder part of the cylinder is hinge-connected to the outer surface of the silo, and the piston rod part of the cylinder is hinge-connected to the intermediate swing arm. When the piston rod of the cylinder expands and contracts, the bottom frame is driven by the connecting rod to move reciprocally in a direction close to or away from the discharge port.

[0017] Adopting the above technical method, as shown in the attached drawings of the specification Figure 1 As shown, the expansion and contraction of the piston rod of the cylinder drive the intermediate swing arm to swing around the main shaft, and because it is circumferentially synchronously rotationally connected to the main shaft, the main shaft is driven to rotate together. At the same time, the side swing arm arranged on the main shaft also swings along with the rotation of the main shaft. Through the hinge connection at both ends of the connecting rod, a connecting rod movement of pulling and pushing the bottom frame is formed, thereby completing the reciprocating movement of the bottom frame.

[0018] The provided hollow groove and the sharp edges are arranged at the edges of the hollow groove relative to the bottom slope, making it smoother when scraping the materials adhered to the inner wall.

[0019] A further setting of the present utility model: Two first hinge seats are symmetrically arranged at the center of the bottom frame, and two sets of first connection grooves, side swing arms, and connecting rods are arranged corresponding to the positions of the two first hinge seats.

[0020] First bearing seats are arranged at both axial ends of the main shaft. The two axial end parts of the main shaft are axially fixed and circumferentially synchronously rotationally connected to two sets of side swing arms respectively. The intermediate swing arm is arranged in the middle section of the main shaft.

[0021] Adopting the above technical solution, as shown in the attached drawings of the specification, two sets of side swing arms and connecting rods symmetrically arranged on both axial sides of the main shaft make the connecting rod movement of the driving mechanism and the bottom frame more stable, the force on the bottom frame more balanced, and the inclination during its movement is avoided.

[0022] A further setting of the present utility model: Both the first side frame and the second side frame include several scraping plates and connecting strips. The several scraping plates are arranged at intervals, and one end is detachably fixedly connected to the bottom frame, and the other end extends towards and fits against the side wall surface. The connecting strip is connected and fixed to several scraping plates on one side.

[0023] By adopting the above technical solution, the length of the scraper can be set according to the condition of the side wall surface by setting a plurality of scrapers. A connection seat is provided at the bottom of the scraper, and the connection seat is detachably fixedly connected to the bottom frame by screws, welding, etc. The connection strips are provided to connect the scrapers on the same side in series so that they are connected as a whole. The gaps between the scrapers form hollow grooves. After the sharp edges are also provided, the scraping effect is improved. Reinforcement ribs can be provided between the scraper and the mounting seat to improve the structural strength.

[0024] The utility model is further configured as follows: the silo is provided with a second connecting groove penetrating to the outer surface of the silo between the discharge port and the bottom frame, and the outer surface of the silo is provided with a second bearing seat at the second connecting groove, the device also includes a special-shaped plate and a second driving mechanism, the special-shaped plate includes a hinge arm, a guide arm, a pressure arm, and a downward probe arm, the special-shaped plate is arranged between the bottom frame and the discharge port, and the hinge arm of the special-shaped plate passes through the second connecting groove and is hingedly connected to the second bearing seat;

[0025] The guide arm extends toward one side of the bottom frame, the lower probe arm extends toward the discharge port, and the pressure arm is arranged between the guide arm and the lower probe arm and extends toward one side of the discharge port;

[0026] The second driving mechanism cooperates with the articulated arm to drive the special-shaped plate to flip around the second bearing seat toward the discharge port, so that the lower probe arm flips and moves deeper into the discharge port.

[0027] By adopting the above technical scheme, when the material is scraped and pushed to one side of the discharge port, if the scraping amount is large and the discharge amount is large, the discharge port may be blocked. Therefore, the special-shaped plate is set to flip back and forth toward the side of the discharge port, and the material on one side of the bottom frame is further guided and moved toward the side of the discharge port by flipping the guide arm. The pressure arm flips with it to press the material downward toward the discharge port, and the lower probe arm swings back and forth from the discharge port to the deep part of the discharge port with the flipping stroke, so as to clear the material blocked in the discharge port and effectively avoid the blockage of the discharge port.

[0028] The utility model is further configured as follows: the special-shaped plate is obliquely provided with an elongated sliding groove, the elongated sliding groove comprises a first end relatively close to the bottom frame, and a second end relatively far away, the distance between the first end and the articulated arm is greater than the distance between the second end and the articulated arm;

[0029] The bottom frame is provided with a push plate portion extending to the long circular slide groove of the special-shaped plate, and the push plate portion is provided with a pin shaft extending into the long circular slide groove for sliding fit. The bottom frame reciprocates to drive the special-shaped plate to flip back and forth toward the discharge port side.

[0030] With the above technical solution, through the structural design of the inclined oval chute, the push plate part, and the pin shaft, a linkage cooperation is formed between the bottom frame and the special-shaped plate. When the bottom frame moves towards the discharge port side, by utilizing the sliding cooperation between the inclined oval chute and the pin shaft, the force of the pin shaft movement is converted into the flipping force for pushing the special-shaped plate to rotate around the hinge arm. When the bottom frame moves relatively away from the discharge port, the retraction of the pin shaft drives the special-shaped plate to swing back. Thus, the second driving mechanism is optimized, and only the first driving mechanism needs to be set.

[0031] Further setting of the present utility model: The device is provided with two parallel and spaced special-shaped plates, and several dial rods extending beyond the special-shaped plates are connected between the two special-shaped plates.

[0032] With the above solution, two parallel and spaced special-shaped plates are connected by several dial rods, forming a gap in the middle, and several dial rods extending beyond the two special-shaped plates also form multiple gaps. By using these gaps, the bulk material is divided into small pieces, making it easier to pass through the discharge port and further avoiding blockage.

[0033] Beneficial effects of the present utility model: Through the mutual cooperation design among the scraping frame, the driving link mechanism, the special-shaped plate, and the silo, a set of linkage cleaning device is formed. Under the action of the reciprocating scraping frame and the special-shaped plate, the adhesive materials on the bottom and side surfaces of the silo can be completely removed. Moreover, the design of this device avoids the existing technical problems of air flow interference and cleaning dead corners. At the same time, through the reciprocating linkage between the bottom frame and the special-shaped plate, a function of preventing blockage at the discharge port is creatively formed. This structure is a pure mechanical mechanism, with relatively lower cost compared to the existing design and achieving a better cleaning effect. Description of the Drawings

[0042] To make the technical solutions and their advantages of this application clearer, the technical solutions of this application will be further described clearly and completely below in conjunction with the drawings. It can be understood that the specific embodiments described here are only partial embodiments of this application, which are only used to explain this application rather than limit this application. It should be noted that for the convenience of description, only the parts related to this application are shown in the drawings, and other related parts can refer to the general design. Without conflict, the embodiments in this application and the technical features in the embodiments can be combined with each other to obtain new embodiments.

[0043] The following will introduce the present utility model in detail in conjunction with the drawings. As Figure 1 and 3 shown, two states of the device under the telescopic stroke of the air cylinder are respectively shown.

[0044] A mechanical material cleaning device for the bottom and side walls of a silo 1, comprising a silo 1, a scraping frame 2, and a first driving mechanism. The silo 1 includes a bottom slope surface 11, two side wall surfaces 12 located on both sides of the bottom slope surface 11, and a discharge port 13, and this discharge port 13 is connected to the low point of the bottom slope surface 11;

[0045] The scraping frame 2 includes a bottom frame 21, a first side frame 22, and a second side frame 23. The contour of the bottom frame 21 is adapted to the contour of the bottom slope surface 11 and is arranged at the bottom slope surface 11 for sliding fit. The first and second side frames 23 are respectively attached to the two side wall surfaces 12 and are both connected to the bottom frame 21;

[0046] The first driving mechanism is linked and cooperated with the bottom frame 21 to drive the bottom frame 21 to move reciprocally in a direction close to or away from the discharge port 13, driving the first and second side frames 23 to scrape the adhesive materials on the bottom slope 11 and the side wall surface 12, and pushing them towards the discharge port 13 side.

[0047] As shown in the attached drawings of the specification Figure 1 As shown, the bin 1 is in a hopper shape (or square). After the carbon black and oily sludge waste gas materials enter the bin 1, they mainly slide down the bottom slope 11 to the discharge port 13. The bottom slope 11 and the two side wall surfaces 12 on both sides of it are the main surfaces in contact with the materials and also the main inner walls where the materials adhere. The inner wall opposite to the bottom slope 11 is vertically arranged. In another embodiment, this inner wall can also be set as a slope, and a set of scraping frames 2 and driving mechanisms can be correspondingly set.

[0048] The reciprocating scraping frame 2 is provided. The bottom frame 21, the first and second side frames 23 are used to scrape the bottom slope 11 and the two side wall surfaces 12, so that the materials sticking to the inner wall are scraped off and are pushed into the discharge port 13 along with the reciprocating push of the scraping frame 2 towards the discharge port 13 side.

[0049] A number of hollow slots 211 are provided on the bottom frame 21. The hollow slots 211 are provided with acute edges relative to the edge of the bottom slope 11. A first hinge seat 212 is provided on the bottom frame 21;

[0050] At the position corresponding to the first hinge seat 212 on the bottom slope 11 and the stroke length, a first connecting slot 213 penetrating through the bin 1 is provided;

[0051] The first driving mechanism includes a cylinder 31, a main shaft 32, an intermediate swing arm 33, a side swing arm 34, and a connecting rod 35. A first bearing seat 321 is provided on the outer surface of the bin 1 at the first connecting slot 213. The main shaft 32 is arranged on the first bearing seat 321 for circumferential rotational cooperation. The main shaft 32 is axially fixed and circumferentially synchronously rotatably connected to the intermediate swing arm 33 and the side swing arm 34 respectively. The side swing arm 34 extends through the first connecting slot 213 into the bin 1. The two ends of the connecting rod 35 are respectively hinge-connected to the first hinge seat 212 and the side swing arm 34. The cylinder part of the cylinder 31 is hinge-connected to the outer surface of the bin 1, and the piston rod part of the cylinder 31 is hinge-connected to the intermediate swing arm 33. When the piston rod of the cylinder 31 expands and contracts, it drives the bottom frame 21 to move reciprocally in a direction close to or away from the discharge port 13 through the connecting rod 35.

[0052] As shown in the attached drawings of the specification Figure 1As shown in the figure, the telescopic movement of the piston rod of the air cylinder 31 drives the intermediate swing arm 33 to swing around the main shaft 32. Since it is circumferentially synchronously rotationally connected to the main shaft 32, the main shaft 32 is driven to rotate around its axis. At the same time, the side swing arm 34 arranged on the main shaft 32 also swings along with the rotation of the main shaft 32. The two ends of the connecting rod 35 are hinged, forming the movement of the connecting rod 35 that pulls and pushes the bottom frame 21, thereby completing the reciprocating movement of the bottom frame 21.

[0053] The provided hollow groove 211 and the edge of the hollow groove 211 relative to the bottom slope 11 are provided with acute edges, making it smoother when scraping the materials adhering to the inner wall.

[0054] Two first hinge seats 212 are symmetrically arranged at the center of the bottom frame 21, and two groups of first connection grooves 213, side swing arms 34, and connecting rods 35 are arranged corresponding to the positions of the two first hinge seats 212.

[0055] First bearing seats 321 are arranged at both axial ends of the main shaft 32. The two axial end portions of the main shaft 32 are axially fixed and circumferentially synchronously rotationally connected to two groups of side swing arms 34 respectively. The intermediate swing arm 33 is arranged in the middle section of the main shaft 32.

[0056] As shown in the attached drawings of the specification, two groups of side swing arms 34 and connecting rods 35 arranged symmetrically on both axial sides of the main shaft 32 make the movement of the connecting rod 35 of the driving mechanism and the bottom frame 21 more stable, the force on the bottom frame 21 more balanced, and avoid tilting during its movement.

[0057] The first side frame 22 and the second side frame 23 each include a plurality of scraping plates 231 and connecting strips 232. The plurality of scraping plates 231 are arranged at intervals, and one end is detachably fixedly connected to the bottom frame 21, and the other end extends towards and fits against the side wall surface 12. The connecting strips are fixedly connected to the plurality of scraping plates 231 on one side.

[0058] By arranging a plurality of scraping plates 231, the length of the scraping plates 231 can be set according to the situation of the side wall surface 12. A connecting seat is provided at the bottom of the scraping plate 231, and the connecting seat is detachably fixedly connected to the bottom frame 21 by means of screws, welding, etc. The provided connecting strips 232 connect each scraping plate 231 on the same side in series to form an integrated body. The gaps between the scraping plates 231 form the hollow groove 211. After setting acute edges in the same way, the scraping effect is improved. Reinforcing ribs can be arranged between the scraping plates 231 and the mounting seat to improve the structural strength.

[0059] The silo 1 is provided with a second connecting groove 214 penetrating to the outer surface of the silo 1 between the discharge port 13 and the bottom frame 21, and a second bearing seat 215 is provided at the second connecting groove 214 on the outer surface of the silo 1. The device further comprises a special-shaped plate 4 and a second driving mechanism. The special-shaped plate 4 comprises a hinge arm 41, a guide arm 42, a pressure arm 43, and a lower probe arm 44. The special-shaped plate 4 is provided between the bottom frame 21 and the discharge port 13, and the hinge arm 41 of the special-shaped plate 4 passes through the second connecting groove 214 and is hingedly connected to the second bearing seat 215;

[0060] The guide arm 42 extends toward one side of the bottom frame 21, the lower probe arm 44 extends toward the discharge port 13, and the pressure arm 43 is disposed between the guide arm 42 and the lower probe arm 44 and extends toward one side of the discharge port 13;

[0061] The second driving mechanism cooperates with the articulated arm 41 to drive the special-shaped plate 4 to flip around the second bearing seat 215 toward the discharge port 13 , so that the lower probe arm 44 flips and moves deeper into the discharge port 13 .

[0062] When the material is scraped off and pushed to the side of the discharge port 13, if the scraping amount is large and the discharge amount is large, the discharge port 13 may be blocked. Therefore, the special-shaped plate 4 is set to flip back and forth toward the side of the discharge port 13, and the guide arm 42 is flipped to further guide and move the material on the side of the bottom frame 21 toward the side of the discharge port 13, and the pressure arm 43 flips to press the material downward toward the discharge port 13, and the lower probe arm 44 swings back and forth from the discharge port 13 to the deep part of the discharge port 13 along the flipping stroke, so as to clear the material blocked in the discharge port 13, thereby effectively avoiding the blockage of the discharge port 13.

[0063] The special-shaped plate 4 is obliquely provided with an elongated sliding groove 45, the elongated sliding groove 45 includes a first end relatively close to the bottom frame 21, and a second end relatively far away, and the distance between the first end and the hinge arm 41 is greater than the distance between the second end and the hinge arm 41;

[0064] The bottom frame 21 is provided with a push plate portion 216 extending to the long circular groove 45 of the special-shaped plate 4, and the push plate portion 216 is provided with a pin shaft 217 extending into the long circular groove 45 for sliding fit. The bottom frame 21 reciprocates to drive the special-shaped plate 4 to flip back and forth toward the discharge port 13 side.

[0065] Through the structural design of the inclined oval chute 45, the push plate portion 216, and the pin shaft 217, an interlocking cooperation is formed between the bottom frame 21 and the special-shaped plate 4. While the bottom frame 21 moves toward the discharge port 13, by means of the sliding cooperation between the inclined oval chute 45 and the pin shaft 217, the force of the movement of the pin shaft 217 is converted into the turning force for pushing the special-shaped plate 4 to rotate around the hinge arm 41. When the bottom frame 21 moves relatively away from the discharge port 13, the retraction of the pin shaft 217 drives the special-shaped plate 4 to swing back. Thus, the second driving mechanism is optimized, and only the first driving mechanism needs to be provided.

[0066] The device is provided with two parallel and spaced special-shaped plates 4, and a number of dial rods 46 extending beyond the special-shaped plates 4 are connected between the two special-shaped plates 4.

[0067] Two parallel and spaced special-shaped plates 4 are connected by a number of dial rods 46 to form a gap in the middle, and a number of dial rods 46 extending beyond the outer sides of the two special-shaped plates 4 also form a plurality of gaps. By using these gaps, the bulk material is divided into small pieces, making it easier to pass through the discharge port 13 and further avoiding blockage.

[0068] Through the mutual cooperation design among the scraping frame 2, the driving link 35 mechanism, the special-shaped plate 4, and the silo 1 in this application, a set of interlocking cleaning device is formed. Under the action of the reciprocating scraping frame 2 and the special-shaped plate 4, the sticky materials on the bottom surface and side surface of the silo 1 can be completely removed. Moreover, the design of this device avoids the existing technical problems of air flow interference and cleaning dead corners. At the same time, through the reciprocating interlock between the bottom frame 21 and the special-shaped plate 4, a function of preventing blockage at the discharge port 13 is creatively formed. This structure is a pure mechanical mechanism, with a relatively lower cost compared to the existing design and achieving a better cleaning effect.

[0069] It can be understood that for those skilled in the art, any equivalent replacement or change to the technical solution and the inventive concept of the present utility model should fall within the protection scope of the claims attached to the present utility model.
