Description

Technical Field

[0001] The utility model relates to the technical field of cement silo production, in particular to a dredging device for the bottom of a cement silo. Background Art

[0002] A cement silo is a crucial device in the cement production and storage process, mainly used for large-scale cement storage. The design and operation of a cement silo involve multiple aspects, among which the bottom discharging system is a key link to ensure the smooth discharge of cement. The bottom discharging system usually includes components such as a discharging port, a discharging chute, and a pressure reducing cone. The design and operation of these components directly affect the discharge efficiency of cement and the continuity of production. During actual use, the discharging chute at the bottom of the silo is prone to material accumulation at the pressure reducing cone, which seriously affects the smooth progress of production. The pressure reducing cone is usually installed above the discharging port to regulate the material flow rate and pressure.

[0003] As a fine-particle powdery material, cement has a certain fluidity but is also prone to moisture absorption and caking. During the bottom discharging process of the silo, cement particles flow through the discharging chute under the action of gravity. Since cement particles are prone to moisture absorption, in a high-humidity environment or after long-term storage, cohesive forces will be generated between cement particles, resulting in an increase in the friction force between particles, and gradually forming lumps during the flow process. These lumps are prone to accumulate at the bottom of the cone when flowing through the pressure reducing cone, leading to the occurrence of material accumulation. However, the existing bottom dredging equipment is large in volume, which reduces the volume of the cement silo, and cannot clean the silo bottom without dead angles at 360°, resulting in poor dredging effect. Summary of the Utility Model

[0004] The utility model provides a dredging device for the bottom of a cement silo to alleviate the problem that the existing equipment cannot clean the cement blocks accumulated at the bottom of the silo in all directions.

[0052] During the bottom discharging process of the silo, cement particles flow through the discharging chute under the action of gravity. Since cement particles are prone to moisture absorption, in a high-humidity environment or after long-term storage, cohesive force will be generated between cement particles, resulting in an increase in the frictional force between particles, and causing them to gradually form lumps during the flowing process. When these lumps flow through the decompression cone, they are prone to accumulate at the bottom of the cone, leading to the occurrence of stockpiling phenomena. The existing bottom dredging equipment in the silo is large in volume, resulting in a smaller volume of the cement silo, and it cannot clean in all directions without dead angles, and the dredging effect is poor.

[0053] In view of this, as Figures 1 to 5 shown, this solution provides a bottom dredging device for a cement silo to alleviate the above problems:

[0054] This device includes a fixed seat 100, a drive assembly 200 and a telescopic support 300;

[0055] The fixed seat 100 is sleeved on the lower part of the telescopic support 300;

[0056] The telescopic support 300 is rotatably connected to the fixed seat 100;

[0057] The upper part of the fixed seat 100 is fixedly connected to the lower end of the discharge port at the bottom of the cement silo;

[0058] The drive assembly 200 can drive the telescopic support 300 to fold;

[0059] A hydraulic hose 400 is arranged inside the telescopic support 300.

[0060] Specifically, when dredging the bottom of the cement silo, the telescopic support 300 is set to a vertical state and inserted into the cement silo along the discharge port at the bottom of the silo, and then docked with the discharge port through the fixed seat 100 to seal the discharge port. Then, the telescopic support 300 is adjusted through the drive assembly 200 to align the nozzle of the hydraulic hose 400 with the inner wall of the cement silo. After connecting the gas tank to the intake end of the hydraulic hose 400, an air injection operation is carried out to make the high-pressure gas spray towards the inner wall of the cement silo to blow and disperse the agglomerated cement particles; the telescopic support 300 can also be rotated and the extended state of the telescopic support 300 can be adjusted to make the nozzle of the hydraulic hose 400 evenly spray towards the inner wall of the cement silo.

[0061] Regarding the shape and structure of the fixed seat 100, as Figure 2 shown:

[0062] The fixed seat 100 includes a fixed flange 110 and a rotating flange 120;

[0063] The rotating flange 120 is arranged below the fixed flange 110.

[0064] Specifically, a bearing is arranged at the center of the rotating flange 120, and the fixed flange 110 is arranged at the upper end of the bearing. The fixed flange 110 is used to fix the bearing and provide sealing for the upper part of the bearing to prevent the upper part of the bearing from being polluted by cement particles. Mounting seats are arranged around the rotating flange 120 for fixedly connecting with the discharge port at the bottom of the silo.

[0065] Regarding the shape and structure of the telescopic support 300, as Figure 1 and Figure 3 shown:

[0066] The telescopic support 300 includes a vertical pipe 310, a movable pipe 320 and a support plate 330;

[0067] The lower part of the vertical pipe 310 is clamped with the bearing inside the rotating flange 120;

[0068] The upper part of the vertical pipe 310 is fixedly connected with the support plate 330;

[0069] The movable pipe 320 is rotatably connected with the support plate 330 through a hinge plate 340.

[0070] Specifically, the movable pipe 320 can rotate along the axis of the hinge plate 340, so that the movable pipe 320 can be adjusted from the state of being close to the support plate 330 to the extended state away from the support plate 330; in the close state, the telescopic support 300 as a whole remains vertical to facilitate passing through the discharge port at the bottom of the silo.

[0071] Regarding the installation position of the hydraulic hose 400, as Figure 1 and Figure 4 shown:

[0072] The hydraulic hose 400 passes through the vertical pipe 310 and the movable pipe 320 in sequence;

[0073] One end of the hydraulic hose 400 is fixedly connected with the vertical pipe 310, and the other end is fixedly connected with the movable pipe 320.

[0074] Specifically, an opening is arranged at the lower part of the vertical pipe 310, and the hydraulic hose 400 can be inserted along the opening. After the installation of the hydraulic hose 400 is completed, the two ends are fixedly connected with the vertical pipe 310 and the movable pipe 320 respectively by welding to ensure that high-pressure gas can be ejected smoothly.

[0075] In this solution, as Figure 1 shown, the drive assembly 200 includes a winch assembly 210 and a pulley assembly 220;

[0076] The winch assembly 210 is disposed at the lower part of the rotating flange 120 and is fixedly connected to the riser 310;

[0077] The pulley assembly 220 is disposed on the side wall of the telescopic bracket 300;

[0078] The winch assembly 210 is rotatably connected to the pulley assembly 220 through a steel wire rope.

[0079] Specifically, the pulley assembly 220 includes a first pulley, a second pulley and a third pulley. The first pulley and the second pulley are disposed on one side of the support plate 330, and the third pulley is disposed at one end of the moving pipe 320 away from the support plate 330; the winch assembly 210 includes a first winch, a second winch and a third winch. The three are fixedly connected by welding with a short plate and are connected to the pulley assembly 220 through a steel wire rope to realize the operations of adjusting the angle, extending and retracting of the moving pipe 320.

[0080] In this solution, as Figure 3 and Figure 4 shown, a long hole 321 is provided at one end of the moving pipe 320 connected to the hinge plate 340;

[0081] The hinge plate 340 is provided with a limiting hole 341 that matches the long hole 321;

[0082] The limiting hole 341 and the long hole 321 are connected by a pin shaft.

[0083] Specifically, when the moving pipe 320 is controlled to retract and extend by the driving assembly 200, the pin shaft moves within the range of the limiting hole 341 to ensure that the hydraulic hose 400 works within an appropriate range; in addition, a dust discharge hole 322 is provided on the side wall of the moving pipe 320. In the vertical state when the moving pipe 320 retracts, the limiting hole 341 is disposed on the side close to the support plate 330, and the dust discharge hole 322 is disposed at the bottom on the side away from the limiting hole 341, so that when the moving pipe 320 extends, the dust discharge hole 322 is at the lowermost end of the moving pipe 320, so that the cement particles excited by the high-pressure gas can flow out along the dust discharge hole 322 after entering the moving pipe 320 from the limiting hole 341.

[0084] In this solution, for the convenience of installation, the fixing seat 100 is provided with a lifting lug 130, and the lifting lug 130 is disposed on one side of the rotating flange 120; in addition, the fixing seat 100 is further provided with an inspection hole 140. The inspection port 140 is used for lighting equipment and camera equipment to enter the inside of the cement silo to detect the state inside the silo. The inspection hole 140 is closed by a baffle during silo cleaning.

[0085] This solution has at least the following beneficial effects:

[0086] The design of this solution provides an effective solution to the blockage problem during the discharging process at the bottom of the cement silo, and has significant beneficial effects. First of all, the cement silo bottom dredging device designed in the solution realizes efficient blockage removal operations inside the cement silo through the coordinated action of the telescopic support 300, the hydraulic hose 400, and the drive assembly 200. When dredging the bottom of the cement silo, the telescopic support can flexibly adjust the angle and position, so that the nozzle of the hydraulic hose can evenly align with the inner wall of the cement silo, quickly blowing away the agglomerated cement particles. Compared with traditional large-scale dredging equipment, this device occupies less space, does not significantly reduce the effective volume of the cement silo, and can greatly improve the dredging effect through 360° dead-angle-free cleaning.

[0087] Secondly, the hydraulic hose 400 in the solution can effectively use air pressure to blow away the bonded particles on the inner wall of the cement silo by jetting high-pressure gas, avoiding the damage that traditional mechanical dredging equipment may cause to the inner wall of the cement silo. The sealed connection between the fixed seat 100 and the discharge port of the cement silo can effectively prevent the leakage of cement particles during the dredging operation, thus maintaining the cleanliness and safety of the operation environment. Moreover, the inspection hole 140 provided on the fixed seat 100 facilitates the operator to monitor the situation inside the cement silo in real time through lighting or camera equipment, ensuring a comprehensive grasp of the internal state of the cement silo.

[0088] Generally speaking, the cement silo bottom dredging device provided by this solution is not only superior to traditional equipment in terms of space occupation and flexibility, but also realizes a more thorough and efficient dredging effect through high-pressure gas cleaning, which can significantly reduce the stacking phenomenon and ensure the normal operation of the cement silo. This device has a simple design and convenient operation, is suitable for application in cement silos of different scales, and has broad market prospects and promotion value.
