Description

Technical Field

[0001] The utility model relates to the technical field of conveying hoppers, in particular to a vibrating hopper. Background Art

[0002] In the modern paper-making industry, efficient and stable raw material supply is one of the key factors to ensure the smooth progress of the production process. When traditional feeding hoppers handle paper-making raw materials, they often face the problem of blockage caused by the relatively light weight of the raw materials.

[0003] Generally, after the paper-making raw materials enter the feeding hopper, it is easy to cause poor flow due to factors such as accumulation, mutual extrusion, and friction with the inner wall of the hopper. This blockage phenomenon will not only reduce the feeding efficiency and affect the overall production progress, but also may lead to production interruption, increasing equipment maintenance and production costs. For example, in some paper mills, when using ordinary hoppers for feeding, due to the light weight characteristics of the raw materials, accumulation often occurs near the outlet or corners of the hopper, and workers need to frequently clean and dredge it, which not only consumes manpower but also delays production time.

[0004] To solve this problem, there have been some previous attempts. For example, in the patent with the publication number CN206842161U, a metal diaphragm is provided inside the hopper, and the metal diaphragm is driven by a vibrator to vibrate the materials on the periphery of the metal diaphragm. However, since the position of the metal diaphragm is fixed and non-adjustable, material blockage is still likely to occur inside the hopper. Content of the Utility Model

[0005] To solve the existing problems, the utility model provides a vibrating hopper. Through the cooperation of a vibrating diaphragm and a push rod, the position of the vibrating diaphragm inside the hopper is adjustable, further reducing the possibility of material blockage inside the hopper and accelerating the feeding speed.

[0006] The utility model provides a vibrating hopper, which includes a hopper main body. The top of the hopper main body is a feeding port, and the bottom is a discharging port. A vibrating diaphragm is arranged inside the hopper main body, and the vibrating diaphragm is connected to an external pulse gas generator. A push rod for adjusting the insertion length of the vibrating diaphragm is arranged outside the hopper main body. The push rod is used to push the vibrating diaphragm into the hopper main body, so that the vibrating diaphragm can not only vibrate on the side wall of the hopper, but also enter the hopper to vibrate, further avoiding material blockage and ensuring smooth feeding.

[0007] Further, the push rod has a fixed end and a telescopic end. The fixed end is fixedly arranged outside the hopper main body through a positioning frame, and the telescopic end is connected to the vibrating diaphragm. A through hole for the telescopic end to pass through is opened on the hopper main body. The telescopic end of the push rod is slidably arranged in the through hole to drive the vibrating diaphragm to expand and contract.

[0008] Further, a connecting pipe is provided between the telescopic end and the vibrating diaphragm. The connecting pipe is slidably arranged in the through hole, and one end of the connecting pipe close to the fixed end is connected to an external pulse gas generator through a gas guide hose. To prevent the telescopic end from directly entering the hopper and causing the material to be carried into the fixed end, affecting the normal operation of the push rod, the connecting pipe is used to drive the vibrating diaphragm into the hopper.

[0009] Further, the hopper body is a square hopper and has four side walls. Four groups of vibrating diaphragms and push rods are provided corresponding to the four side walls. The vibrating diaphragm and the push rod form a vibration unit, and vibration units are arranged on each side wall, which can effectively prevent material blockage.

[0010] Further, a flanging is provided along the upper edge of the hopper body, and a support frame is provided below the hopper body. The flanging of the hopper body is arranged on the support frame through an elastic member. Through the arrangement of the elastic member, the hopper body and the support frame are elastically connected and will automatically move slightly up and down according to the amount of material in the hopper, thereby further preventing material blockage.

[0011] Further, the elastic member includes a double-headed bolt and a spring. One end of the double-headed bolt is screwed on the support frame, and the other end is sleeved with a spring and then penetrates through the flanging. A limit nut is screwed on the double-headed bolt penetrating through the flanging, and the flanging is slidably arranged with the double-headed bolt through the spring. The middle section of the double-headed bolt is a smooth section, and the flanging slides up and down along the smooth section under the pressure of the material in the hopper.

[0012] Further, a sealing ring is provided on the outer side of the through hole, and the connecting pipe sequentially passes through the sealing ring and the through hole and enters the inside of the hopper body. The sealing ring can not only seal the through hole, but also scrape off the material attached to the outer surface of the connecting pipe.

[0013] Further, a discharge hard pipe and a discharge flexible pipe are sequentially connected at the discharge port, and a valve for opening and closing is provided on the discharge hard pipe. The valve on the hard pipe is used to open and close the discharge, and the discharge flexible pipe is used to facilitate the introduction of the material into the equipment of the next process.

[0014] The beneficial effects of the present utility model are as follows:

[0015] The present utility model provides a vibrating hopper. By arranging an adjustable pulse gas vibrating diaphragm inside the hopper body, the vibrating diaphragm can extend into different positions inside the hopper body under the drive of the push rod, thereby reducing the possibility of material blockage inside the hopper and effectively improving the discharging efficiency.

[0021] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings. Obviously, the described embodiments are some embodiments of the present invention, rather than all embodiments.

[0022] In order to avoid the situation that the material is blocked at the discharge port and affects the feeding, a vibrating hopper is designed. As Figure 1 shown, it includes a hopper body 1. The top of the hopper body 1 is the feeding port, and the bottom of the hopper body 1 is the discharge port. A vibration diaphragm 2 is arranged inside the hopper body 1. The vibration diaphragm 2 is connected to an external pulse gas generator, and a push rod 3 for adjusting the insertion length of the vibration diaphragm 2 is arranged outside the hopper body 1.

[0023] After the papermaking raw materials enter the inside of the hopper body 1, the position of the vibration diaphragm 2 extending into the hopper can be adjusted by the push rod 3, and vibration is carried out at different positions of the hopper body 1 close to the discharge port, so as to reduce the blockage of the papermaking raw materials at the discharge port, ensure smooth feeding, and since the papermaking raw materials are light in weight, the push rod 3 can smoothly extend into the raw material pile, and the raw materials will not cause damage to the push rod 3 and the vibration diaphragm 2.

[0024] The push rod 3 has a fixed end and a telescopic end. The fixed end is fixedly arranged outside the hopper main body 1 through a positioning frame 13. The telescopic end is connected with a vibration diaphragm 2. A through hole through which the telescopic end can pass is provided on the hopper main body 1. In order to protect the push rod 3, a connecting pipe 4 is also arranged between the telescopic end and the vibration diaphragm 2. The connecting pipe 4 is slidably arranged in the through hole. One end of the connecting pipe 4 close to the fixed end is connected with an external pulse gas generator through a gas guide hose 5. Here, the external pulse gas generator can be any device that can deliver pulse gas. The movement of the vibration diaphragm 2 is driven by the telescopic end of the push rod 3 to drive the connecting pipe 4 to slide in the through hole, avoiding the situation that the telescopic end directly extends into the raw material pile and brings the raw materials into the push rod 3, thus affecting the normal operation of the push rod 3.

[0025] In order to further improve the vibration effect and avoid material blockage, the hopper main body 1 is a square hopper and has four side walls. Four groups of vibration diaphragms 2 and push rods 3 are arranged corresponding to the four side walls.

[0026] In order to facilitate the discharge of the materials in the hopper main body 1, a discharge hard pipe 11 and a discharge flexible pipe are successively connected at the discharge port. A valve 12 for opening and closing is arranged on the discharge hard pipe 11. The discharge hard pipe 11 is opened and closed through the valve 12 on it, and then the materials are introduced into the equipment of the next process by using the discharge flexible pipe. Usually, the hopper main body 1 is placed on the second floor, and the stirring device is placed on the first floor. A hole is opened on the floor slab and the discharge flexible pipe is placed in it. The bagged raw materials are lifted by a crane and poured into the hopper main body 1, and the raw materials fall along the discharge flexible pipe to the stirring device on the first floor for mixing.

[0027] As Figure 2 shown, in order to facilitate the fixation of the hopper main body 1, a flange 6 is arranged along the upper edge of the hopper main body 1, and a support frame 7 is arranged below the hopper main body 1. The hopper main body 1 can be directly welded on the support frame 7, or the flange 6 can be arranged on the support frame 7 through an elastic member.

[0028] Specifically, the elastic member includes a double-headed bolt 10 and a spring 8. One end of the double-headed bolt 10 is screwed on the support frame 7, and the other end is sleeved with the spring 8 and then penetrates through the flange 6. A limit nut 9 is screwed on the double-headed bolt 10 penetrating through the flange 6 to limit the flange 6. The flange 6 is slidably arranged with the double-headed bolt 10 through the spring 8. The double-headed bolt 10 is a rod body with external threads at both ends. When the papermaking raw materials enter the inside of the hopper main body 1, the falling raw materials will cause a downward pressure on the hopper main body 1, driving the hopper main body 1 to move downward. When the hopper main body 1 moves downward, the spring 8 will be compressed. When the raw materials in the hopper main body 1 decrease, the spring 8 will reset and drive the hopper main body 1 to move upward, thus repeatedly driving the hopper main body 1 to move up and down, applying kinetic energy to the materials in the hopper by using the up and down movement, and reducing the blockage phenomenon during feeding.

[0029] As Figure 3As shown in the figure, in order to ensure the sealing performance at the telescopic part of the connecting pipe 4, a sealing ring is provided on the outer side of the through hole. The connecting pipe 4 passes through the sealing ring and the through hole in sequence and enters the inside of the hopper body 1. The sealing ring is bonded to the outer wall of the hopper body 1 with strong glue, which can not only seal the through hole, but also scrape off the materials adhering to the outer surface of the connecting pipe 4.

[0030] The above description is illustrative rather than restrictive to the present utility model. Those of ordinary skill in the art understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the appended claims, and all of them will fall within the protection scope of the present utility model.
