Description

Technical Field

[0001] The utility model relates to the technical field of bulk powder transfer and transportation, in particular to a screw conveyor with a breaking function. Background Art

[0002] Screw conveyors are widely used in various sectors of the national economy, such as the grain industry, building materials industry, chemical industry, machinery manufacturing industry, and transportation industry. Screw conveyors, commonly known as auger, are a type of conveying equipment that is widely used in the mineral, feed, grain and oil, and construction industries. They are made of steel and are mainly used to convey various powdered, granular, and small block materials. When the screw shaft rotates, due to the gravity of the material and the friction between the material and the trough wall, the material can only move forward along the bottom of the conveyor trough under the push of the blades, just like a nut that cannot rotate moves in translation along the rotating screw. The main forward driving force of the material comes from the force of the spiral blades that push the material upward and forward along the tangential direction of the blades when the spiral blades rotate axially.

[0003] During the production process, we found that when conveying some powdery materials with poor fluidity such as titanium dioxide, the materials are very likely to form bridges above the spiral feed port. The spiral cannot unload materials when it is idling, so we have no choice but to arrange workers to continuously knock on the bottom of the storage bin to shake the materials off. This measure will not only cause deformation and damage to the storage bin, but also seriously waste manpower. In order to solve this problem, we designed this screw conveyor with a breaking function to solve the problem of material bridging in screw conveying. Utility Model Content

[0004] The purpose of the utility model is to provide a screw conveyor with a breaking function in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a screw conveyor with a breaking up function, comprising a spiral shell, a breaking up shaft, a spiral shaft, a spiral shaft sprocket chain assembly, a breaking up shaft sprocket chain assembly, a spiral shaft power assembly, a breaking up shaft power assembly and an air hammer, wherein a fluidizing chamber and a conveying chamber are arranged inside the spiral shell, the breaking up shaft is located in the fluidizing chamber, and the breaking up shaft cooperates with the air hammer located on the outer wall of the fluidizing chamber through rotation to form a vibrating fully fluidized zone, and the spiral shaft is located in the conveying chamber.

[0006] Preferably, the spiral blades on the spiral shaft are of variable pitch structure to prevent material from being squeezed and causing the blades to deform or the shaft to get stuck.

[0007] Preferably, the screw shaft is connected to the screw shaft powertrain via a screw shaft sprocket chain assembly.

[0008] Preferably, the scattering shaft is connected to the scattering shaft power assembly via a scattering shaft sprocket chain assembly.

[0009] Compared with the prior art, the advantages of the utility model are: the spiral feed port is designed as an open rectangular feed port, which increases the material drop area and is conducive to material drop, and a breaking shaft is added in the fluidizing chamber, and the breaking shaft power assembly drives the breaking shaft to rotate, and cooperates with the air hammer vibration of the outer wall of the chamber to make the bridging material fully fluidized and fall into the conveying chamber; by driving the spiral shaft power assembly to rotate the spiral shaft, the material moves forward along the conveying chamber under the push of the blades, thereby solving the problem that the material with poor fluidity bridges above the spiral feed port and cannot be dropped.

DETAILED DESCRIPTION

[0015] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0017] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0018] See also Figure 1-3 As shown, a screw conveyor with a breaking function includes a spiral shell 1, a breaking shaft 2, a screw shaft 3, a screw shaft sprocket chain assembly 4, a breaking shaft sprocket chain assembly 5, a screw shaft power assembly 6, a breaking shaft power assembly 7 and an air hammer 8.

[0019] In this embodiment, Figure 2 As shown, the spiral housing 1 includes a fluidizing chamber 101 and a conveying chamber 102 .

[0020] Furthermore, the breaking shaft 2 is located in the fluidizing chamber 101, and the breaking shaft 2 rotates, and the air hammer 8 on the outer wall of the chamber vibrates, so that the bridging material is fully fluidized and falls into the conveying chamber 102. Reinforcement ribs are arranged outside the feed port of the spiral shell 1 to prevent the shell from being broken due to the hammer 8 hitting it.

[0021] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the spiral shaft sprocket chain assembly 4 connects the spiral shaft 3 and the spiral shaft power assembly 6, and the sprocket chain assembly 5 connects the sprocket shaft 2 and the sprocket shaft power assembly 7.

[0022] Furthermore, the screw shaft 3 is located in the conveying cavity 102, and the screw blades are designed to have variable pitches to prevent material from being squeezed and causing the blades to deform or the shaft to get stuck.

[0023] Furthermore, the screw shaft power assembly 6 and the breaking shaft power assembly 7 are respectively located on both sides of the device, so as to substantially maintain the force balance of the device.

[0024] The rotation of the breaking shaft 2 can effectively prevent the material from bridging at the spiral feed port, and the vibration of the air hammer 8 can effectively shake off the material hanging on the wall. Finally, the material smoothly enters the spiral conveying cavity, and is discharged into the next unit from the discharge port as the blades advance.

[0025] In summary, when the device is used, it can solve the problem of material bridging at the spiral feed port, causing the spiral to run idle and unable to transport materials.
