Technical Field

[0001] The invention relates to the technical field of hopper conveying, and in particular to a flexible hopper device. Background Art

[0002] In the chemical industry and other industries, the properties of various materials are different. For the storage and transportation of materials with poor fluidity, conventional silos are difficult to achieve their functions. Flexible hoppers are usually used for transportation. Flexible hoppers are widely used in many industrial fields due to their flexibility, versatility and high cost-effectiveness. By selecting appropriate materials and designs, flexible hoppers can meet various material handling needs and improve production efficiency and product quality.

[0003] However, for materials that are wet, sticky or uneven in particle size, some materials may remain inside after a batch of materials is conveyed, causing problems such as mixing excess materials when new materials are subsequently conveyed. At the same time, after the existing technology conveys the materials, the materials will remain on the inner wall or in the cracks of the equipment, which can easily cause a poor working environment and affect the normal operation of the equipment in the long run.

[0004] In addition, the existing flexible hopper is often fixed by bolts or clamps, which requires frequent maintenance work, resulting in difficulty in installation and disassembly. In addition, the existing flexible hopper may be excessively deformed during use due to excessive weight, squeezing, or collision of materials. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0032] Example 1

[0033] A flexible hopper device, such as Figure 1-Figure 8 As shown, it includes a hopper body 1; it also includes a hopper rubber sleeve 2, a fixing mechanism 3, a flapping mechanism 4 and a pipe clamping mechanism 5; the hopper body 1 is connected to the fixing mechanism 3; the fixing mechanism 3 is connected to the hopper rubber sleeve 2, and the upper part of the hopper rubber sleeve 2 is an inclined part, and the lower part of the hopper rubber sleeve 2 is a vertical part, and the hopper rubber sleeve 2 is provided with a shaping ring 2003, which is used to keep the inclined part of the hopper rubber sleeve 2 in an expanded state; the hopper body 1 is connected to the flapping mechanism 4, and the flapping mechanism 4 is connected to the middle part of the hopper rubber sleeve 2; the flapping mechanism 4 is connected to the pipe clamping mechanism 5, and the pipe clamping mechanism 5 is connected to the bottom of the hopper rubber sleeve 2.

[0034] The hopper body 1 includes a top cover 101, a feed pipe 103 and a support member 104; a plurality of circumferentially distributed lock buckles 10101 are arranged on the top cover 101, and the top cover 101 is arranged in two parts, and the upper and lower parts of the top cover 101 are fixed by the lock buckles 10101; at least four feed pipes 103 are arranged on the upper part of the top cover 101; the bottom of the top cover 101 is connected to the support member 104, and a curved portion 2001 is arranged on the upper part of the hopper rubber sleeve 2, and the support member 104 is located on the inner wall of the curved portion 2001.

[0035] The present invention works specifically as follows:

[0036] The bottom of the hopper rubber sleeve 2 is clamped and closed by the tube clamping mechanism 5, and the required material is passed from the feed pipe 103 into the hopper rubber sleeve 2. When the formula requirements are met and the material needs to be discharged, the tube clamping mechanism 5 cancels the closure of the bottom of the hopper rubber sleeve 2. At the same time, the hopper rubber sleeve 2 is fully vibrated by the flapping mechanism 4 to fully fluidize and assist the flow of the material. In this way, the use of the hopper rubber sleeve 2 and the flapping mechanism 4 can achieve the effects of no fixed inner wall, full diameter, no bonding, no leakage and no blockage when conveying materials.

[0037] It should be noted that the support member 104 props up the hopper rubber sleeve 2 to form a curved portion 2001, and fixes the top of the hopper rubber sleeve 2 through the fixing mechanism 3. Therefore, when the material enters the hopper rubber sleeve 2, the support member 104 is used to block the material, thereby preventing some of the material from being stuck in the connection gap between the hopper rubber sleeve 2 and the fixing mechanism 3. This is different from the prior art that directly uses bolts or clamps to fix it, so that a small gap is formed between it and the fixed area, causing the material to be stuck in the gap.

[0038] Furthermore, the hopper rubber sleeve 2 is provided with a shaping ring 2003, which is located at the angle between the inclined portion and the vertical portion of the hopper rubber sleeve 2. When the hopper rubber sleeve 2 is deformed by the clamping mechanism 5, the inclined portion can remain expanded to avoid deformation.

[0039] Example 2

[0040] On the basis of Example 1, Figure 1-Figure 7 As shown, the fixing mechanism 3 includes a fixing member 301, an elastic rope 302 and a retaining member 303; the fixing member 301 is connected to the bottom of the top cover 101; the fixing member 301 is connected to the elastic rope 302; the hopper body 1 is movably connected to a plurality of circumferentially distributed retaining members 303, and the elastic rope 302 passes through the upper part of the retaining member 303.

[0041] The fixing mechanism 3 further includes a limiting ring 304 ; the top cover 101 is connected to the limiting ring 304 , and a plurality of rubber wheels 30401 are arranged on the limiting ring 304 , and the limiting ring 304 is arranged to fit the surface of the bending portion 2001 .

[0042] A locking head 30301 is provided at the bottom of the locking member 303, and the locking head 30301 is made of magnetic material. The support member 104 is made of iron material. A plurality of first grooves 2002 are provided on the hopper rubber sleeve 2, and each locking head 30301 corresponds to a position of a first groove 2002. A plurality of second grooves 10401 are provided on the support member 104, and each second groove 10401 corresponds to a position of a first groove 2002.

[0043] The present invention works specifically as follows:

[0044] By manually pulling the elastic rope 302, the elastic rope 302 contracts and drives the retaining member 303 to rotate, so that the retaining member 303 fits the hopper rubber sleeve 2 and squeezes it to fit the support member 104. At the same time, the elastic rope 302 is clamped by the fixing member 301 to limit the rebound of the elastic rope 302, so that the retaining member 303 keeps squeezing the hopper rubber sleeve 2, thereby completing the fixation of the hopper rubber sleeve 2. When the hopper rubber sleeve 2 needs to be disassembled and maintained, the restriction of the fixing member 301 on the elastic rope 302 is cancelled, and the retaining member 303 is reset, thereby canceling the squeezing of the hopper rubber sleeve 2. At this time, the hopper rubber sleeve 2 can be easily removed from the support member 104 manually, thereby improving the convenience of equipment operation.

[0045] Furthermore, when it is necessary to install the hopper rubber sleeve 2, the top of the hopper rubber sleeve 2 can be passed through the limiting ring 304, and the limiting ring 304 can be used to squeeze the curved portion 2001 supported by the support 104, thereby enhancing the effect of preventing some materials from getting stuck in the gap. At the same time, the rubber wheel 30401 can be used to assist manual labor in passing the hopper rubber sleeve 2 through the limiting ring 304, thereby improving operational convenience.

[0046] Furthermore, when the locking member 303 squeezes the hopper rubber sleeve 2, the locking head 30301 on the locking member 303 can be restricted by the first groove 2002 and the second groove 10401 to prevent slipping during squeezing. At the same time, the locking head 30301 set with magnetic material can be made to fit the first groove 2002 and the second groove 10401 and squeeze the hopper rubber sleeve 2, and a magnetic attraction force is formed between the locking head 30301 and the support member 104 made of iron material, thereby increasing the fixing effect of the locking member 303 on the hopper rubber sleeve 2, and avoiding the problem of the hopper rubber sleeve 2 falling off when the flapping mechanism 4 is working and causing the equipment to shake.

[0047] Example 3

[0048] On the basis of Example 2, Figure 1-Figure 8As shown, the beating mechanism 4 includes a mounting frame 401, a pneumatic hammer 402, a vibration motor 403, a first electric push rod 404 and a connecting block 405; the top cover 101 is connected to the mounting frame 401; a plurality of pneumatic hammers 402 distributed left and right are installed on the mounting frame 401, and the output end of each pneumatic hammer 402 is connected to the middle part of the hopper rubber sleeve 2; two vibration motors 403 distributed left and right are installed in the middle part of the mounting frame 401, and the two vibration motors 403 are connected to the shaping ring 2003 together; two first electric push rods 404 distributed front and back are installed at the bottom of the mounting frame 401; the telescopic ends of the two first electric push rods 404 are fixedly connected to a connecting block 405, and the hopper rubber sleeve 2 is provided with a fixing sleeve 2004, and the connecting block 405 is engaged with the inside of the fixing sleeve 2004.

[0049] The pipe clamping mechanism 5 includes a second electric push rod 501 and a clamping plate 502 and a first electric push rod 404; the mounting frame 401 is installed with two second electric push rods 501 distributed on the left and right; the telescopic ends of the two second electric push rods 501 are fixedly connected with a clamping plate 502, and the clamping plates 502 are located on the left and right sides of the bottom of the hopper rubber sleeve 2.

[0050] A plurality of protrusions 50201 are disposed on the two clamping plates 502, and the heights of the protrusions 50201 on the left and right sides are arranged in an alternating manner.

[0051] The present invention works specifically as follows:

[0052] When the material is discharged through the hopper rubber sleeve 2, the pneumatic hammer 402 continuously vibrates the hopper rubber sleeve 2, and by providing at least four pneumatic hammers 402, sufficient flow assistance for the material is achieved to avoid the problem of the material staying on the inner wall of the hopper rubber sleeve 2.

[0053] Furthermore, before the pipe clamping mechanism 5 needs to clamp and close the vertical part of the hopper rubber sleeve 2, the two first electric push rods 404 can drive the two connecting blocks 405 engaged in the fixed sleeve 2004 to move toward the opposite sides thereof, and drive the vertical part of the hopper rubber sleeve 2 to stretch in the front-to-back direction. At this time, the two second electric push rods 501 can drive the two clamping plates 502 to move toward the opposite sides thereof until the inner wall of the vertical part of the hopper rubber sleeve 2 is fitted. This can avoid the problem of wrinkles on the vertical part of the hopper rubber sleeve 2 caused by direct clamping, which seriously reduces the service life of the hopper rubber sleeve 2.

[0054] Furthermore, a plurality of protrusions 50201 are provided on both clamps 502, and the heights of the protrusions 50201 on the left and right sides are staggered up and down, so that when the two clamps 502 move toward their opposite sides, the protrusions 50201 on the two clamps 502 can be engaged with each other, thereby increasing the sealing of the vertical part of the hopper rubber sleeve 2.

[0055] Example 4

[0056] On the basis of Example 3, Figure 6 As shown, the hopper body 1 also includes a multi-stage electric telescopic tube 102; the middle of the top cover 101 is connected to the multi-stage electric telescopic tube 102 for passing gas to prevent part of the material from remaining inside the hopper rubber sleeve 2.

[0057] A tuyere 10201 is provided at the bottom of the multi-stage electric telescopic tube 102, and the tuyere 10201 is elliptical in shape for diffusing the incoming airflow.

[0058] The gas washing operation of the present invention is specifically as follows:

[0059] Connect the external gas transmission equipment to the top of the multi-stage electric telescopic tube 102. After the material is discharged, some of the material may not fall out of the hopper rubber sleeve 2 due to its own viscosity or small volume. At this time, the gas can be passed into the multi-stage electric telescopic tube 102 by opening the external gas transmission equipment, and blown out from the bottom to the inside of the hopper rubber sleeve 2, so that the blown gas blows the material remaining on the inner wall of the hopper rubber sleeve 2 downward to complete the gas washing of the equipment. It should be noted that when the gas is passed in, the multi-stage electric telescopic tube 102 can be extended and retracted to adjust the distance between the multi-stage electric telescopic tube 102 and the inner wall of the hopper rubber sleeve 2, thereby adjusting the gas flow. The size of the collision force when the multi-stage electric telescopic tube 102 contacts the material. When the multi-stage electric telescopic tube 102 is extended, it is close to the inner wall of the hopper rubber sleeve 2. When the gas is blown out from the bottom of the multi-stage electric telescopic tube 102, the diffusion range is small, and it will contact the material remaining on the inner wall of the hopper rubber sleeve 2 faster. The collision force is large, and the stubborn residual material can be air washed. When the multi-stage electric telescopic tube 102 is contracted, it is far away from the inner wall of the hopper rubber sleeve 2. When the gas is blown out from the bottom of the multi-stage electric telescopic tube 102, the diffusion range is large, and the diffused gas contacts the material remaining on the inner wall of the hopper rubber sleeve 2. The collision force is small, and a larger range of residual materials can be air washed.

[0060] Furthermore, a tuyere 10201 is provided at the bottom of the multi-stage electric telescopic tube 102, and the tuyere 10201 is elliptical and used to diffuse the incoming airflow, thereby increasing the air washing range. It should be noted that the multi-stage electric telescopic tube 102 can be extended to make the tuyere 10201 close to the vertical part of the hopper rubber sleeve 2. During the clamping process of the clamping plate 502, the elliptical tuyere 10201 has the same shape as the vertical part of the hopper rubber sleeve 2 during the clamping process, thereby better performing air washing on the vertical part of the hopper rubber sleeve 2.

[0061] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
