Description

Technical Field

[0001] This utility model belongs to the technical field of feeding devices for drying viscous materials, and specifically relates to a novel viscous material feeding bin. Background Technology

[0002] Sticky materials refer to materials with a moisture content of 15% or higher. When feeding sticky materials to a dryer, a feeding hopper is needed to ensure uniform and stable feeding. Existing feeding hoppers consist of a rigid impeller and a shell, with the discharge delivered by a twin-screw conveyor. The connection between the feeding hopper and the twin screws is an insert-type rigid connection. For example, patent CN218056707U discloses a sticky material discharge hopper, which is divided into upper and lower parts. The upper hopper is inserted into the lower hopper, shortening the material stacking height and reducing the risk of blockage. However, this discharge hopper lacks a stirring device, making it impossible to control the discharge speed and causing the sticky material to easily agglomerate and clump in the hopper, hindering discharge.

[0003] Currently, ordinary feeding hoppers consist of rigid blades and a shell, with material discharged by a twin-screw conveyor. This structure has several drawbacks: 1. Sticky materials enter from above the hopper; without a dispersing device, this can lead to clumping, material buildup on the inner walls, and uneven discharge, affecting feeding operations; 2. The rigid insertion connection between the feeding hopper and the twin screw conveyor can easily cause material to be squeezed outwards; 3. The twin-screw conveyor with a shaft is susceptible to motor jamming if there are hard lumps in the sticky material. Utility Model Content

[0004] The purpose of this invention is to provide a novel viscous material feeding bin to solve the problem mentioned in the background art that the existing viscous material feeding bins do not achieve ideal storage and conveying effects.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel viscous material feeding bin, comprising a cylindrical bin body, an inlet at the top center of the bin body, a conical agitator arranged along the axis inside the bin body, multiple sets of agitating blades and multiple layers of crushing blades arranged on the outside of the agitator, the bottom end of the agitator's rotating shaft passing through the bin body and fixedly connected to the output end of a drive motor, and a discharge port near the bottom edge of the bin body, with a screw conveyor connected to the discharge port.

[0006] Preferably, the screw conveyor is a shaftless double screw conveyor.

[0007] Preferably, four mounting brackets are symmetrically distributed along the circumference on the upper part of the outer side of the silo body, and are connected to the support frame through the mounting brackets.

[0008] Preferably, each of the four mounting brackets is equipped with a weighing component.

[0009] Preferably, the feed end of the screw conveyor is connected to the discharge port of the silo body via a flexible connection.

[0010] Preferably, the agitator has two layers of shredders welded along the axial direction. Each layer of shredders includes two sets of stainless steel blades arranged symmetrically at 180°, and the two layers of shredders are vertically staggered.

[0011] Preferably, the weighing component is connected to an external display via a data cable.

[0012] Preferably, the multiple sets of stirring blades are symmetrically arranged at the bottom of the agitator, with the inner ends of the stirring blades welded to the agitator and the outer ends in contact with the inner wall of the chamber.

[0013] Compared with the prior art, the beneficial effects of the novel viscous material feeding bin provided by this utility model are:

[0014] 1. The feeding hopper uses a conical agitator set along its axis. Sticky material falling from the feed inlet at the top of the hopper lands on the conical agitator and disperses downwards. Two layers of cutting blades are welded to the agitator, each layer symmetrically distributed at 180°. The two layers of blades are perpendicular to each other to increase the probability of breaking up the incoming material. In practical applications, the number of blade layers and the rotation speed of the agitator can be determined based on the properties of the sticky material and the feeding speed. When material falls from the feed inlet onto the agitator, the rotating cutting blades cut through any clumps of material, ensuring the uniformity of the sticky material.

[0015] 2. The discharge port of the feed hopper and the feed port of the screw conveyor are connected by a flexible joint, which effectively prevents raw material spillage and is easier to connect than a straight connection. This is because the flexible joint can achieve a tight seal between the feed hopper and the screw conveyor, and slight relative movement between the two will not cause the flexible joint to break.

[0016] 3. The discharge end of the feeding hopper adopts a shaftless double spiral conveyor, which can transport viscous materials evenly, prevent clogging, and ensure stable operation.

[0017] 4. The feeding bin is connected to the support frame through four mounting brackets on the upper side of the bin body. Each mounting bracket is equipped with a weighing component, which can display the weight of the material in the bin in real time. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1 , 2 This utility model provides: a novel viscous material feeding bin, comprising a cylindrical bin body 1, with a feed inlet 11 at the top center of the bin body 1 and a discharge port 12 near the bottom edge. A screw conveyor 3 is connected to the discharge port 12 via a telescopic flexible hose.

[0023] Inside the silo 1, a conical agitator 2 is arranged along its axis. Agitator blades 21 and multiple layers of crushing blades 22 are arranged on the outside of agitator 2. The bottom end of the agitator 2's rotating shaft extends through the bottom of the silo 1 and is rotatably connected to the bottom surface of the silo 1 via a sealed bearing. The bottom end of the rotating shaft is fixedly connected to the output end of the drive motor 5. Three sets of agitator blades 21 are symmetrically arranged. The agitator blades 21 are located at the bottom of agitator 2, with their inner ends welded to agitator 2 and their outer ends contacting the inner wall of the silo 1. While agitating, they scrape the inner wall of the silo 1 and push the material out through the discharge port 12. Two layers of crushing blades 22 are welded along the axial direction. These are made of stainless steel, and each layer of crushing blades 22 has two sets of blades welded symmetrically at 180° intervals. The upper and lower layers of crushing blades 22 are vertically distributed.

[0024] Four mounting brackets 4 are symmetrically assembled along the circumference of the upper outer surface of the silo body 1. The silo body 1 is connected to the rigid support frame through the mounting brackets 4. Weighing components are installed at each of the four mounting brackets 4. The weighing components use existing weighing sensors. The weighing sensors are connected to a display through data transmission lines, which can weigh the materials in the silo body 1 and display the weight in real time.

[0025] The screw conveyor 3 is a shaftless double screw conveyor. There are two screw blades arranged axially inside the conveyor. The ends of the two screw blades are connected to a conveying motor to control the rotation of the two screw blades to convey materials in the same direction.

[0026] This utility model patent provides a novel viscous material feeding hopper. In application, the feeding hopper is vertically mounted on a rigid support frame via four mounting brackets 4. Four sets of weighing components perform the weighing function. The weighing components are connected to an external display via a data cable to display the weight of the material inside the hopper in real time. The viscous material enters through the feed inlet 11 of the feeding hopper and falls onto the agitator 2 at the bottom under gravity. The agitator 2, driven by the drive motor 5, performs a circular motion. The crushing blade 22 and the stirring blade 21 also perform a circular motion under the drive of the agitator 2. Large clumps of material are crushed into smaller pieces by the cutting action of the crushing blade 22. The rotation and stirring of the stirring blade 21 maintains the uniformity of the material. Simultaneously, the material enters the screw conveyor 3 through the discharge port 12. The discharge speed of the material is adjusted by controlling the rotation speed of the agitator. The material is then transported to the subsequent dryer by the screw conveyor 3.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
