Description

Technical Field

[0001] This utility model relates to the field of vacuum suction hopper technology, specifically to a wear-resistant particle vacuum suction hopper structure. Background Technology

[0002] Vacuum hoppers are widely used for conveying powdery or granular materials. They utilize a vacuum pump to generate negative pressure, which draws the material into the hopper. The filter screen inside the hopper separates the air from the material. When the hopper is full of material, the vacuum pump is turned off, the valve at the bottom of the hopper opens automatically, and the material falls into the receiving equipment due to gravity.

[0003] Publication number CN220054952U discloses an anti-clogging vacuum hopper that uses an upper and lower cone to separate and disperse materials, reducing material accumulation. Through a lower and side air inlet, it allows outside air to quickly enter during material discharge, balancing the internal and external pressure difference and thus preventing blockage at the outlet. However, this patent still has the following problems in practical use:

[0004] By using the upper and lower cones to separate and disperse the material, the accumulation of material is reduced. The lower and side air inlets allow outside air to enter quickly when the material is discharged, balancing the internal and external pressure difference and preventing blockage at the outlet. However, when the particles are vacuum-suctioned into the hopper, they will cause a large impact and knocking on the hopper wall, which will gradually thin the hopper wall over time.

[0005] A wear-resistant particle vacuum suction hopper structure is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a wear-resistant particle vacuum hopper structure to solve the problem mentioned in the background art. Currently, materials are separated and dispersed by an upper and lower cone to reduce material accumulation. The lower and side air inlets allow outside air to enter quickly during material discharge, balancing the internal and external pressure difference and preventing blockage at the outlet. However, when particles are vacuum-suctioned into the hopper, they cause significant impact and impact on the hopper wall, which gradually thins the hopper wall over time.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant particle vacuum suction hopper structure, comprising a connecting frame and a receiving bin, wherein the top surface of the connecting frame is connected through the receiving bin;

[0008] A discharge pipe is connected through the middle of the bottom surface of the receiving hopper, and a discharge valve is fixedly installed inside the discharge pipe. A discharge pipe is connected through the middle of the top surface of the receiving hopper, and a conveying pipe is connected through the top surface of the discharge pipe. A mounting frame is connected through one side surface of the conveying pipe, and one side of the bottom surface of the mounting frame is fixedly connected to the receiving hopper. A buffer baffle is installed on the bottom surface of the conveying pipe.

[0009] Also includes:

[0010] The top surface of the buffer baffle is symmetrically provided with mounting components;

[0011] The mounting components include a sleeve that is connected through the buffer baffle;

[0012] A tie rod is connected through the inside of the sleeve.

[0013] Preferably, a first spring is sleeved on the surface of the pull rod, one side of the first spring is fixedly connected to the sleeve, and a sliding plate is fixedly connected to the other side of the first spring. One side of the pull rod is fixedly connected to the sliding plate.

[0014] Preferably, the sleeve is symmetrically mounted with fixing frames on both sides, and a limiting rod is connected through the middle of the fixing frame. A second spring is sleeved on the surface of the limiting rod. The bottom surface of the second spring is fixedly connected to the sleeve, and the top surface of the second spring is fixedly connected to the fixing frame. The limiting rod is connected through the sleeve.

[0015] Preferably, a locking rod is fixedly connected to the middle of the side surface of the slide away from the first spring, and limit grooves are symmetrically formed on both sides of the locking rod, and the limit grooves are engaged with the limit rod.

[0016] Preferably, a suction hopper is attached to the bottom surface of the buffer baffle, and a sealing ring is bonded to the perimeter of the buffer baffle, with the outer wall of the sealing ring being attached to the suction hopper.

[0017] Preferably, a screen is fixedly installed inside the conveying pipe, a plurality of damping blocks are fixedly installed on one side of the screen, a damping spring is fixedly connected to the surface of the damping block away from the screen, and a perforated plate is fixedly connected to the surface of the damping spring away from the damping block.

[0018] Preferably, the conveying pipe has symmetrical slots on one side surface near the bottom, and the slots are engaged with the locking rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This wear-resistant particle vacuum suction hopper structure, by setting a buffer baffle and mounting components, allows the buffer baffle to buffer the impact force of the particles, thus protecting the side hopper wall while allowing observation of the suction status inside the hopper through the viewing window. Furthermore, the mounting components make the installation and removal of the buffer baffle more convenient. The specific details are as follows:

[0020] 1. By setting up the installation components, when the buffer baffle needs to be replaced, pulling the limiting rod separates it from the limiting groove. Then, pulling the pull rod moves the slide plate. This movement compresses the first spring, causing it to deform. Simultaneously, the slide plate moves the locking rod. Once the locking rod reaches a certain position, it separates from the locking groove, thus separating the buffer baffle from the conveying pipe. Furthermore, when installing the buffer baffle, the buffer baffle... After the top of the plate is attached to the bottom of the conveying pipe, the sliding plate returns to its original position under the action of the first spring by loosening the pull rod. The movement of the sliding plate can drive the movement of the locking rod, so that the locking rod can engage with the locking groove on the conveying pipe. At the same time, by loosening the limiting rod, the limiting rod returns to its original position under the action of the second spring, so that the limiting rod can engage with the limiting groove, thus limiting the pull rod. This completes the installation between the buffer baffle and the conveying pipe, thereby improving the efficiency of installing and disassembling the buffer baffle and the conveying pipe.

[0021] 2. By setting up a screen, damping block, damping spring, and perforated plate, after the particles are conveyed into the conveying pipe, the particles will impact the perforated plate, causing the perforated plate to move. At the same time, the movement of the perforated plate will compress the damping spring, causing the damping spring to deform. Through the cooperation between the damping spring and the damping block, the impact force on the perforated plate can be buffered, thereby reducing the impact force on the screen and improving the service life of the screen.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a wear-resistant particle vacuum suction hopper structure, including a connecting frame 1 and a receiving bin 2. The top surface of the connecting frame 1 is connected to the receiving bin 2 through the middle; a discharge pipe 3 is connected through the middle of the bottom surface of the receiving bin 2, and a discharge valve 4 is fixedly installed inside the discharge pipe 3. A discharge pipe 5 is connected through the middle of the top surface of the receiving bin 2, and a conveying pipe 6 is connected through the top surface of the discharge pipe 5. A mounting frame 7 is connected through one side surface of the conveying pipe 6, and one side of the bottom surface of the mounting frame 7 is fixedly connected to the receiving bin 2. A buffer baffle 8 is installed on the bottom surface of the conveying pipe 6. It also includes: mounting components 9 symmetrically arranged on the top surface of the buffer baffle 8; wherein, the mounting component 9 includes a sleeve 901 that is connected through the buffer baffle 8; wherein, a pull rod 902 is connected through the inside of the sleeve 901, such as... Figure 1-5 As shown, by setting the buffer baffle 8 and the mounting component 9, the buffer baffle 8 can buffer the impact force of the particles, so as to protect the side wall of the hopper and observe the material suction status inside the hopper through the viewing window. At the same time, the mounting component 9 makes it easier to install and remove the buffer baffle 8. The buffer baffle 8 is made of tempered glass with a thickness of 10 mm, and the bottom of the buffer baffle 8 is slightly inclined, which facilitates the entry of particles into the interior of the conveying pipe 6.

[0030] A first spring 903 is fitted onto the surface of the pull rod 902. One side of the first spring 903 is fixedly connected to the sleeve 901, and a slide plate 904 is fixedly connected to the other side of the first spring 903. One side of the pull rod 902 is fixedly connected to the slide plate 904. Fixing brackets 905 are symmetrically installed on both sides of the sleeve 901. A limiting rod 906 is connected through the center of the fixing bracket 905. A second spring 907 is fitted onto the surface of the limiting rod 906. The bottom surface of the second spring 907 is fixedly connected to the sleeve 901, and the top surface of the second spring 907 is fixedly connected to the fixing bracket 905. The limiting rod 906 is connected through the sleeve 901. A locking rod 908 is fixedly connected to the center of the side of the slide plate 904 away from the first spring 903. Limiting grooves 909 are symmetrically formed on both sides of the locking rod 908. The limiting grooves 909 engage with the limiting rod 906. Figure 4 , 5 As shown, when installing the buffer baffle 8, after the top of the buffer baffle 8 is attached to the bottom of the conveying pipe 6, the pull rod 902 is loosened, causing the slide plate 904 to return to its original position under the action of the first spring 903. The movement of the slide plate 904 can drive the movement of the locking rod 908, thereby causing the locking rod 908 to engage with the locking groove 16 on the conveying pipe 6. At the same time, by loosening the limiting rod 906, the limiting rod 906 returns to its original position under the action of the second spring 907, thereby causing the limiting rod 906 to engage with the limiting groove 909, thus limiting the pull rod 902. This completes the installation between the buffer baffle 8 and the conveying pipe 6, thereby improving the efficiency of installing and disassembling the buffer baffle 8 and the conveying pipe 6. The first spring 903 and the second spring 907 are both compression springs in the prior art.

[0031] A suction hopper 10 is attached to the bottom surface of the buffer baffle 8, and a sealing ring 11 is bonded to the perimeter of the buffer baffle 8. The outer wall of the sealing ring 11 is attached to the suction hopper 10. Figure 2 As shown, the sealing ring 11 prevents air leakage, and the buffer baffle 8 is connected to the suction hopper by a connecting snap-fit ​​in the prior art.

[0032] A screen 12 is fixedly installed inside the conveying pipe 6. Several damping blocks 13 are fixedly installed on one side of the screen 12. A damping spring 14 is fixedly connected to the surface of the damping block 13 away from the screen 12. A perforated plate 15 is fixedly connected to the surface of the damping spring 14 away from the damping block 13. Figure 3As shown, after the particles are conveyed into the conveying pipe 6, they impact the perforated plate 15, causing the perforated plate 15 to move. At the same time, the movement of the perforated plate 15 compresses the damping spring 14, causing the damping spring 14 to deform. Through the cooperation between the damping spring 14 and the damping block 13, the impact force on the perforated plate 15 can be buffered, thereby reducing the impact force on the screen 12 and thus improving the service life of the screen 12.

[0033] The conveying pipe 6 has symmetrically formed slots 16 on one side surface near the bottom. The slots 16 engage with the locking rod 908. Figure 4 , 5 As shown, the clamping rod 908 engages with the slot 16 on the conveying pipe 6, thereby improving the efficiency of installing and removing the buffer baffle 8 and the conveying pipe 6.

[0034] Working principle: Before using this type of wear-resistant particle vacuum suction hopper structure, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 As shown in Figure 5, under negative pressure, the material in the storage hopper is first sucked into the suction hopper 10 through the conveying pipe 6. At the same time, the discharge valve 4 is closed. During the conveying process, the material enters the interior of the conveying pipe 6 along with the air. Then, through the action of the screen 12, the air and material are separated. The material falls automatically under the action of gravity and is collected in the receiving bin 2. When the material is collected at the set value of the suction hopper 10, the suction is stopped by time control. The air stop valve inside the conveying pipe 6 is opened, and air enters the other side of the screen 12. Then, the material falls into the interior of the receiving bin 2 by its own weight.

[0035] Secondly, when the buffer baffle 8 needs to be replaced, by pulling the limiting rod 906, the limiting rod 906 is separated from the limiting groove 909. Then, by pulling the pull rod 902, the pull rod 902 can drive the slide plate 904 to move. The movement of the slide plate 904 will compress the first spring 903, causing the first spring 903 to deform. At the same time, when the slide plate 904 moves, it can drive the locking rod 908 to move. After the locking rod 908 moves to a certain position, the locking rod 908 separates from the locking groove 16, thereby separating the buffer baffle 8 from the conveying pipe 6. Furthermore, when installing the buffer baffle 8, by... After the top of the conveying pipe 6 is attached to the bottom, the sliding plate 904 returns to its original position under the action of the first spring 903 by loosening the pull rod 902. The movement of the sliding plate 904 can drive the movement of the locking rod 908, so that the locking rod 908 can engage with the locking groove 16 on the conveying pipe 6. At the same time, by loosening the limiting rod 906, the limiting rod 906 returns to its original position under the action of the second spring 907, so that the limiting rod 906 can engage with the limiting groove 909, thereby limiting the pull rod 902. This completes the installation between the buffer baffle 8 and the conveying pipe 6, thereby improving the efficiency of installing and disassembling the buffer baffle 8 and the conveying pipe 6.

[0036] Finally, after the particles are conveyed into the conveying pipe 6, they impact the perforated plate 15, causing the perforated plate 15 to move. At the same time, the movement of the perforated plate 15 compresses the damping spring 14, causing the damping spring 14 to deform. Through the cooperation between the damping spring 14 and the damping block 13, the impact force on the perforated plate 15 can be buffered, thereby reducing the impact force on the screen 12 and thus improving the service life of the screen 12.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
