Abstract
Description
Technical Field
[0001] This utility model relates to the field of asphalt production technology, specifically to an asphalt filtration device for asphalt production. Background Technology
[0002] Asphalt is a dark brown, complex mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid, appearing liquid with a black surface, and is soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementing material. Asphalt can be mainly classified into three types: coal tar pitch, petroleum asphalt, and natural asphalt. Coal tar pitch is a byproduct of coking. Petroleum asphalt is the residue after crude oil distillation. Natural asphalt is stored underground, sometimes forming mineral layers or accumulating on the earth's surface. Asphalt is mainly used in the coatings, plastics, and rubber industries, as well as in road paving.
[0003] During asphalt production, a filtration device is needed to filter the asphalt. The filter screen inside the filtration device needs to be disassembled and cleaned regularly. However, the process of disassembling and cleaning the filter screen is cumbersome, which leads to the inconvenience of cleaning the filter screen. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an asphalt filtration device for asphalt production, which has the advantages of easy disassembly of the filter screen, thus solving the problem of inconvenient filter screen disassembly.
[0005] This utility model discloses an asphalt filtration device for asphalt production, comprising a filter box. The top of the filter box has a cover, and the top of the cover has a feed inlet. The bottom of the front of the filter box has a discharge outlet. A filter assembly is located at the top of the inner cavity of the filter box. The filter assembly includes two placement concave plates, which are fixedly connected to both sides of the inner cavity of the filter box. A filter screen is located at the top of the two placement concave plates. Limiting rods are located at both ends of the top of each placement concave plate. Limiting holes, matching the limiting rods, are opened at the four corners of the inner cavity of the filter screen. Locking holes are opened at both ends of both sides of the filter screen. Movable plates are located at both ends of the top of each placement concave plate. A locking rod is movably fitted inside the inner cavity of each movable plate, and the inner side of the locking rod engages with the locking hole. A baffle is fitted on the inner side of the surface of the locking rod. A tension spring is located at the connection between the outer side of the baffle and the movable plate, and the tension spring is fitted onto the surface of the locking rod. A rotating rod is rotatably connected to the outer side of the locking rod. A guide wheel is fixedly fitted on the surface of the rotating rod. The device includes a matching inclined plate with an electric push rod at its top. When the filter needs to be disassembled, the electric push rod moves upward, causing the inclined plate to move upward. During this upward movement, the inertia of the tension spring causes the baffle to move outward, which in turn causes the locking rod to move outward. The locking rod then moves stably within the movable plate, and the guide wheel on its outer side moves outward against the inclined surface of the plate. When the locking rod moves out of the locking hole, the filter can move upward. Once the limiting hole on the filter moves out of the limiting rod, the filter can be cleaned. After cleaning and placing the filter in the designated position, the electric push rod moves downward, causing the inclined plate to move downward. The inclined plate then pushes the guide wheel inward, which in turn moves the locking rod inward. When the locking rod moves into the locking hole, the filter is fixed in place. This makes cleaning the filter more convenient, avoiding the cumbersome process of disassembling and cleaning the filter, which can lead to inconvenient cleaning.
[0006] The present invention relates to an asphalt filtration device for asphalt production, wherein the top and bottom of the surface of the electric push rod are fixedly fitted with limiting plates, and the outer side of the limiting plates is fixedly connected to the filter box. The limiting plates can fix the electric push rod, thus improving the performance of the electric push rod during use and preventing the electric push rod from shaking and becoming unstable.
[0007] The present invention relates to an asphalt filtration device for asphalt production, wherein baffles are provided on both sides of the bottom of the box cover, and the bottom of the baffles is in close contact with the filter screen. Through the baffles, when the asphalt is transmitted to the filter box through the feed inlet for filtration, the baffles can act as baffles to prevent the asphalt from scattering on both sides of the filter screen and causing the clamping mechanism on both sides of the filter screen to malfunction.
[0008] The present invention relates to an asphalt filtration device for asphalt production, wherein the bottom of the filter box is provided with an anti-slip mat, and the bottom of the anti-slip mat is provided with anti-slip particles. The anti-slip mat can prevent the filter box from moving during use, thereby preventing the filter box from having poor performance.
[0009] The present invention relates to an asphalt filtration device for asphalt production, wherein a guide plate is provided at the bottom of the inner cavity of the filter box, and the inclination angle of the guide plate is not less than 45 degrees.
[0010] The present invention relates to an asphalt filtration device for asphalt production, wherein the two sides of the inner cavity of the filter box are fixedly connected to the placement concave plates by welding, and the two placement concave plates are arranged symmetrically about the filter box.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. When the filter screen needs to be disassembled, the electric push rod first moves upward, driving the inclined plate upward. During the upward movement of the inclined plate, the inertia of the tension spring drives the baffle to move outward, which in turn drives the locking rod to move outward. At this time, the locking rod will move stably within the movable plate, and the guide wheel on the outside of the locking rod will move outward against the inclined surface of the inclined plate. When the locking rod moves out of the locking hole, the filter screen can move upward. When the limiting hole on the filter screen moves out of the limiting rod, the filter screen can be cleaned. After the filter screen is cleaned and placed in the designated position, the electric push rod moves downward, driving the inclined plate downward. The inclined plate pushes the guide wheel inward, which in turn drives the locking rod inward. When the locking rod moves into the locking hole, the filter screen can be fixed. This makes cleaning the filter screen more convenient and avoids the cumbersome process of disassembling and cleaning the filter screen, which leads to inconvenient cleaning.
[0013] 2. This utility model uses a limiting plate to fix the electric push rod, which makes the electric push rod perform better during use and avoids shaking during use, thus preventing the electric push rod from becoming unstable.
[0014] The baffle plate can block the asphalt when it is fed into the filter box through the inlet for filtration, thus preventing the asphalt from scattering on both sides of the filter screen and causing the clamping mechanism on both sides of the filter screen to malfunction.
[0015] The anti-slip mat prevents the filter box from slipping, thus avoiding movement during use and ensuring its effectiveness. Attached Figure Description

[0024] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.
[0025] Please see Figure 1-6The present invention relates to an asphalt filtration device for asphalt production, comprising a filter box 1, a cover 4 on the top of the filter box 1, an inlet 6 on the top of the cover 4, an outlet 3 at the bottom of the front of the filter box 1, a filter assembly 5 on the top of the inner cavity of the filter box 1, the filter assembly 5 comprising two placement concave plates 501, the two placement concave plates 501 being fixedly connected to the two sides of the inner cavity of the filter box 1 respectively, a filter screen 504 on the top of the two placement concave plates 501, a limiting rod 502 at both ends of the top of the placement concave plates 501, and limiting holes 503 adapted to the limiting rods 502 at the four corners of the inner cavity of the filter screen 504, the filter screen 504 having limiting holes 503 on both sides. Both ends of the plate are provided with locking holes 5014. Both ends of the top of the recessed plate 501 are provided with movable plates 505. The inner cavity of the movable plate 505 is movably fitted with a locking rod 506, and the inner side of the locking rod 506 is engaged with the locking hole 5014. The inner side of the surface of the locking rod 506 is fitted with a baffle 507. The outer side of the baffle 507 is provided with a tension spring 508 at the connection between it and the movable plate 505, and the tension spring 508 is fitted on the surface of the locking rod 506. The outer side of the locking rod 506 is rotatably connected with a rotating rod 5013. The surface of the rotating rod 5013 is fixedly fitted with a guide wheel 509. The surface of the guide wheel 509 is provided with a matching inclined plate 5012. The top of the inclined plate 5012 is provided with an electric push. When the filter screen 504 needs to be disassembled, the electric push rod 5010 moves upward, driving the inclined plate 5012 upward. During the upward movement of the inclined plate 5012, the inertia of the tension spring 508 causes the baffle 507 to move outward, which in turn causes the locking rod 506 to move outward. At this time, the locking rod 506 moves stably within the movable plate 505, and the guide wheel 509 on the outer side of the locking rod 506 moves outward against the inclined surface of the inclined plate 5012. When the locking rod 506 moves out of the locking hole 5014, the filter screen 504 can move upward. When the positioning hole 503 moves out of the limiting rod 502, the filter screen 504 can be cleaned. After the filter screen 504 is cleaned and placed in the designated position, the electric push rod 5010 moves downward, which drives the inclined plate 5012 to move downward. The inclined plate 5012 pushes the guide wheel 509 to move inward, which drives the locking rod 506 to move inward. When the locking rod 506 moves into the locking hole 5014, the filter screen 504 can be fixed. This makes cleaning the filter screen 504 more convenient and avoids the cumbersome process of disassembling and cleaning the filter screen 504, which would otherwise make cleaning the filter screen 504 inconvenient.
[0026] The top and bottom of the electric push rod 5010 are fixedly fitted with limiting plates 5011, and the outer side of the limiting plates 5011 is fixedly connected to the filter box 1. The limiting plates 5011 can fix the electric push rod 5010, so that the electric push rod 5010 performs better when in use and avoids the electric push rod 5010 shaking during use, which would lead to the unstable operation of the electric push rod 5010.
[0027] Both sides of the bottom of the box cover 4 are provided with baffle plates 7, and the bottom of the baffle plates 7 is in close contact with the filter screen 504. Through the baffle plates 7, when the asphalt is transmitted to the filter box 1 through the feed inlet 6 for filtration, the baffle plates 7 can play a role in blocking the asphalt, preventing the asphalt from scattering on both sides of the filter screen 504 and causing the snap-fit mechanism on both sides of the filter screen 504 to malfunction.
[0028] The bottom of the filter box 1 is provided with an anti-slip pad 2, and the bottom of the anti-slip pad 2 is provided with anti-slip particles. The anti-slip pad 2 can prevent the filter box 1 from slipping, thus preventing the filter box 1 from moving during use and thus preventing the filter box 1 from having poor performance.
[0029] The bottom of the inner cavity of filter box 1 is provided with a guide plate, and the tilt angle of the guide plate is not less than 45 degrees.
[0030] The two sides of the inner cavity of the filter box 1 are fixedly connected to the placement concave plate 501 by welding, and the two placement concave plates 501 are arranged symmetrically about the filter box 1.
[0031] When using this utility model: When it is necessary to disassemble the filter screen 504, firstly, the electric push rod 5010 moves upward, which drives the inclined plate 5012 to move upward. During the upward movement of the inclined plate 5012, the inertia of the tension spring 508 will drive the baffle 507 to move outward, which in turn drives the locking rod 506 to move outward. At this time, the locking rod 506 will move stably within the movable plate 505, and the guide wheel 509 on the outer side of the locking rod 506 will move outward against the inclined surface of the inclined plate 5012. When the locking rod 506 moves out of the locking hole 5014, the filter screen 504 can move upward. When the positioning hole 503 moves out of the limiting rod 502, the filter screen 504 can be cleaned. After the filter screen 504 is cleaned and placed in the designated position, the electric push rod 5010 moves downward, which drives the inclined plate 5012 to move downward. The inclined plate 5012 pushes the guide wheel 509 to move inward, which drives the locking rod 506 to move inward. When the locking rod 506 moves into the locking hole 5014, the filter screen 504 can be fixed. This makes cleaning the filter screen 504 more convenient and avoids the cumbersome process of disassembling and cleaning the filter screen 504, which would otherwise make cleaning the filter screen 504 inconvenient.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
