Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical equipment, in particular to a petroleum coke sealing loading and unloading door. Background Art

[0002] When petroleum coke is processed in petrochemical industry, water and coke blocks are mixed and injected into the dehydration bin from the top of the bin. As the bin is filled, clear water overflows from the top of the dehydration bin. When the coke blocks reach the predetermined height, the injection is stopped, and then the coke and water are left to stand for separation. After 10 hours, the water is separated through the filter screen into the drainage pipe. Finally, the bottom loading and unloading door is opened to discharge the dehydrated petroleum coke and transport it to the next step.

[0003] The ash discharge gates (also known as loading and unloading gates) currently in use have certain defects. The gap between the loading and unloading gates and the ash discharge port of the dehydration bin is difficult to adjust. Support nuts are used for adjustment, but such adjustment methods often require manual operation, and the adjustment gaps cannot be guaranteed to be the same, which can easily lead to partial poor sealing and water leakage.

[0004] In order to avoid water leakage, the prior art has adopted an inflatable sealing ring on the ash discharge port. When the ash discharge port and the ash discharge gate need to be sealed, the two are sealed by inflating the sealing ring to deform and expand. This sealing structure requires the sealing ring to be inflated and deflated, which increases the time for opening or closing the ash discharge port and is not conducive to rapid unloading. In addition, since the sealing ring is inside the ash discharge port, it is impossible to determine whether the sealing ring has achieved the sealing effect, which may easily cause the ash discharge gate to be opened without complete deflation, thereby causing the sealing ring to rub and break, which not only fails to achieve the sealing effect, but also increases the sliding resistance of the ash discharge gate.

[0005] At the same time, the water in the dehydration bin will flow out through the gaps, affecting the working environment. At the same time, since the sealed bin bottom of the gate cannot effectively drain water, a large amount of water will accumulate and be discharged during unloading, seriously polluting the on-site environment. Seals must be replaced frequently and maintenance and cleaning must be performed. Utility Model Content

[0049] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0050] The present embodiment relates to a sealed petroleum coke loading and unloading door, which comprises a frame 1 having an inner cavity arranged at the lower end of an ash discharge port 15, a door body 2 driven to move relative to the ash discharge port 15, and a first driving part 3 and a second driving part 4 arranged in the frame 1. The first driving part 3 drives the door body 2 to move back and forth along the length direction of the frame 1, so that the door body 2 blocks or opens the ash discharge port 15, and the second driving part 4 drives the door body 2 to move back and forth along the height direction of the frame 1, so that the door body 2 blocks or opens the ash discharge port 15. An annular seal 5 is provided on the plane of the door body 2 close to the ash discharge port 15. When the door body 2 blocks the ash discharge port 15, the annular seal 5 abuts against the corresponding position of the dehydration bin and deforms, and the inner hole of the annular seal 5 is larger than the inner hole of the ash discharge port 15.

[0051] The petroleum coke sealed loading and unloading door of this embodiment is provided with a first driving part 3 to drive the door body 2 to move back and forth along the length direction of the frame 1, so that the door body 2 can block or open the ash discharge port 15, and the second driving part 4 is provided to reciprocate the door body 2 along the height direction of the frame 1, and the door body 2 is provided with an annular seal 5. When the door body 2 blocks the ash discharge port 15, the annular seal 5 can form a sealing ring between the door body 2 and the ash discharge port 15 to avoid water leakage. When the door body 2 needs to be opened for unloading, the second driving part 4 is away from the door body 2, and the door body 2 is away from the ash discharge port 15 due to its own weight. At this time, the first driving part 3 drives the door body 2 to move and open the ash discharge port 15, which can effectively ensure that the annular sealing ring will not be worn or damaged due to the movement of the door body 2, thereby ensuring the sealing effect, and increasing the moving speed of the door body 2, thereby improving the unloading efficiency.

[0052] Based on the above overall introduction, an exemplary structure of the petroleum coke sealed loading and unloading door of this embodiment is as follows: Figures 1 to 3 As shown, the frame 1 is formed as a rectangular ring frame, and the first drive part 3 and the second drive part 4 both use hydraulic cylinders, wherein one end of the first drive part 3 is pivotally connected to the inner side of the frame 1 , and its power output end is connected to the lower end of the door body 2 .

[0053] As Figures 1 to 3As shown, the door body 2 is a rectangular structure. In order to ensure the stability of the door body 2 moving up and down, four second driving parts 4 are provided in this embodiment. The power output end of each second driving part 4 is connected to a rubber sleeve 12. The rubber sleeve 12 can increase the contact area with the door body 2 and reduce the impact. The four second driving parts 4 are respectively connected to the side walls of the frame 1.

[0054] In order to improve the flexibility of the door body 2 in opening the ash discharge port 15, Figures 1 to 3 As shown, a plurality of rollers 10 are arranged at intervals along the length direction of the frame 1, and the rollers 10 are pivotally connected to the inner wall of the frame 1. Two rows of rollers 10 are respectively arranged on two opposite surfaces of the frame 1, and when the power output end of the second driving part 4 is away from the door body 2, the two ends of the base 201 overlap on the two rows of rollers 10.

[0055] like Figure 6 As shown, the roller 10 of this embodiment is connected to the side wall of the frame 1 through a pin 11, a pressure cover 13 is provided on the outside of the frame 1, and the pressure cover 13 and the pin 11 are fixedly connected by bolts, and a deep groove ball bearing is provided between the roller 10 and the pin 11. During processing, it is necessary to ensure that the line connecting the highest points of each roller 10 is parallel to the ash discharge port 15. In this embodiment, by setting a second driving part 4, the door body 2 is driven close to the ash discharge port 15, and fine adjustment can be performed when the door body 2 is not parallel to the ash discharge port 15, which reduces the straightness requirement for the installation of the roller 10, and reduces the processing and assembly requirements.

[0056] As a preferred implementation mode, Figures 3 to 5 As shown, the frame 1 is provided with a connecting plate 6 connected to the dehydration bin, and the connecting plate 6 is connected to a side of the door body 2 with an annular buffer 7, and the inner hole of the annular buffer 7 is larger than the outer shape of the annular seal 5. When the door body 2 blocks the ash discharge port 15, the annular buffer 7 abuts against the door body 2. The annular seal 5 of this embodiment is made of a harder nitrile rubber material, and its cross-section can be an O-shaped, rectangular, polygonal or other structure. The annular buffer 7 can be made of a softer rubber material.

[0057] By providing the connection plate 6 and the annular buffer 7, a certain buffering effect can be played when the second driving part 4 presses against the door body 2, thereby preventing the connection between the discharge door and the dehydration bin from failing due to the impact. In addition, by providing the annular buffer 7, another seal is formed on the outer ring of the annular seal 5 to further increase the sealing effect, thereby preventing water leakage between the ash discharge port 15 and the door body 2, and improving the use effect of the sealed discharge door.

[0058] like Figure 4 and Figure 5As shown, the middle of the connecting plate 6 is provided with an opening 601, and the lower part of the dehydration bin passes through the opening 601 and abuts against the annular seal 5. The shape of the lower part of the dehydration bin is adapted to the opening 601, and the connecting plate 6 is provided with a mounting portion connected to the dehydration bin. The opening 601 of this embodiment is set according to the shape of the lower part of the dehydration bin, and the opening 601 in this embodiment is a round hole. Figure 4 As shown, the lower part of the dehydration bin has a cylinder 16 protruding downward. When the door body 2 is driven close to the ash discharge port 15 , the cylinder 16 passes through the opening 601 and abuts against the annular seal 5 .

[0059] like Figure 3 As shown, the mounting portion is a plurality of through holes provided on the connecting plate 6, and the dehydration bin is provided with threaded holes corresponding to the through holes, and the loading and unloading door is connected to the dehydration bin by bolts. By providing the mounting portion on the connecting plate 6, it is convenient to connect the unloading door to the dehydration bin, and the shape of the lower part of the dehydration bin is adapted to the opening 601, and the lower part of the dehydration bin is guided and limited by the opening 601 to ensure the abutment effect between the dehydration bin and the annular seal 5.

[0060] Further, as Figure 4 and Figure 5 As shown, the door body 2 includes a base 201 and a gate plate 202 disposed on the base 201. An annular groove is disposed on the plane of the gate plate 202, and an annular seal 5 is disposed in the annular groove. A through hole 2021 is also disposed in the center of the gate plate 202, and an outlet 2011 is disposed on the base 201. The through hole 2021 communicates the opening 601 and the outlet 2011.

[0061] like Figure 4 and Figure 5 As shown, the gate plate 202 is provided with an opening 601 groove for setting the filter screen 17, and the filter screen 17 is fixedly connected to the gate plate 202. By setting the filter screen 17, excessive ash can be prevented from entering the water outlet pipe 8 described below, thereby improving the ash separation effect.

[0062] Still Figure 4 and Figure 5 As shown, a receiving chamber 2012 is provided in the base 201, and a through hole 2021 is provided in the middle of the gate plate 202, and water from the ash discharge port 15 flows into the receiving chamber 2012 through the through hole 2021. By providing the through hole 2021 and the receiving chamber 2012, a water filtering effect is played before unloading, so that a large amount of water and ash are prevented from being sent into the unloading vehicle together during unloading, and the effect of pre-separating ash is achieved, thereby effectively avoiding the problem of ash and slurry water being unloaded at the same time in the prior art, causing serious pollution on site, and reducing subsequent maintenance and cleaning work.

[0063] Furthermore, if Figures 1 to 3As shown, a water outlet pipe 8 is provided on one side of the frame 1, a guide portion 9 is provided on one side of the gate plate 202 near the water outlet pipe 8, a water inlet 801 is provided on the water outlet pipe 8, and the guide portion 9 has a protruding portion 901 extending toward the water inlet 801. The water outlet pipe 8 is provided to facilitate the collection of filtered water.

[0064] like Figures 1 to 3 As shown, the outlet pipe 8 includes a rectangular collecting pipe and a flange pipe. The collecting pipe is a rectangular structure with an inner cavity. Correspondingly, the guide portion 9 is extended along the width direction of the gate plate 202, and the water inlet 801 is arranged along the length direction of the collecting pipe. Its length is greater than the guide portion 9, and the extending portion 901 extends to the water inlet 801 to avoid partial water leakage.

[0065] like Figure 4 As shown, the guide part 9 of this embodiment is made of a bent plate connected up and down, and one end of the bent plate is fixedly welded to the gate plate 202. If water leakage occurs due to failure of both the annular seal 5 and the annular buffer 7, the water flow can be transported to the outlet pipe 8 through the guidance of the upper plane of the guide part 9.

[0066] In addition, Figure 4 As shown, the flow guide 9 is provided with a communication port 902 communicating with the accommodating chamber 2012, and the outlet 2011 of the extending portion 901 is provided in the water outlet pipe 8. The communication port 902 in this embodiment can be a long hole arranged along the length direction of the flow guide 9, or can be a plurality of long holes or circular holes arranged at intervals, which is not limited here. The two bent plates and the side surface of the gate plate 202 form a water outlet chamber, and the extending portion 901 has a sharp corner portion, which forms the outlet 2011 of the water outlet chamber. When the water volume is too much and fills the accommodating chamber 2012, it can flow into the water outlet pipe 8 through the communication port 902.

[0067] Furthermore, if Figure 1 As shown, a scraper 14 is provided on one side of the connecting plate 6, and the scraper 14 is used to scrape off the ash residue on the filter screen 17. By providing the scraper 14, the ash residue covering the filter screen 17 can be removed while the door body 2 moves. In addition, a brush can be provided under the scraper 14 to improve the removal effect of the ash residue on the filter screen.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
