Description

Technical Field

[0001] The present invention relates to the technical field of Euro bins, and in particular to a detachable modular gear sleeve device for a Euro bin spiral mechanism. Background Art

[0002] Eurosilo is a closed storage system similar to a silo, which provides a storage solution for non-free-flowing solid bulk materials and large storage requirements. Due to its non-free-flow design concept, it ensures the stability of feeding and discharging of viscous materials such as desulfurized gypsum, limestone powder and other materials. The materials are accumulated and stored in horizontal layers, entering from the top of the silo, falling through the telescopic drop pipe, and distributed to various parts of the drop layer by the screw conveyor controlled by the revolving trestle suspension. Therefore, the conveying capacity of the screw mechanism is the key to ensure the fluidity of the material when feeding and discharging.

[0003] At present, due to certain differences between the design process of foreign Euro warehouses and the actual use environment in China, the outer teeth of the Euro warehouse spiral mechanism are severely worn and the conveying capacity is significantly reduced, resulting in instability when the material is fed in and out, which seriously affects the service life of the spiral mechanism. It also causes tension fluctuations in the wire rope connecting the spiral mechanism, affecting the safe and stable operation of the equipment. At the same time, since the original spiral mechanism is an integral casting, the tooth surface needs to be replaced as a whole after wear, the material waste rate is high (about 70% or more), and the overall replacement cost is high, the replacement is difficult, and the time-consuming is long. Therefore, there is an urgent need for a new type of gear sleeve device that can adapt to China's complex working conditions, a modular, highly wear-resistant, and easy-to-replace device, to solve the problems of fast wear, difficult maintenance, and high cost in the prior art. Summary of the invention

[0004] The object of the present invention is to provide a detachable modular gear sleeve device for a Euro bin screw mechanism which is easy to replace.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A detachable modular gear sleeve device for a Euro warehouse spiral mechanism, which is used to be covered and installed on the base of the spiral mechanism. The detachable modular gear sleeve device includes a gear sleeve body matching the base and bolt holes arranged on the gear sleeve body. The bolt holes are used to install the gear sleeve body on the base by bolts. The gear sleeve body includes symmetrically arranged fan rings, bow-shaped connecting pieces and external teeth. The bow-shaped connecting pieces are respectively connected to the outermost arc edges of two fan rings, and the external teeth are arranged on the bow-shaped connecting pieces.

[0007] Furthermore, the base is a polished spiral blade in the spiral mechanism.

[0008] Furthermore, the bolt holes are arranged in multiple rows, with multiple bolt holes in each row.

[0009] Further, the bolt holes are arranged on two sector rings, and the bolt holes on the two sector rings correspond to each other.

[0010] Further, on each of the sector rings, double rows of bolt holes are arranged at preset intervals of angle.

[0011] Further, the central angle of the sector ring is 60 degrees, 90 degrees, 120 degrees or 180 degrees.

[0012] Further, the sector ring, the bow-shaped connecting piece and the external teeth are integrally designed to form the tooth sleeve body.

[0013] Further, a positioning pin hole is further included, and the positioning pin hole is arranged at both ends of the sector ring for circumferential positioning when the tooth sleeve body is installed.

[0014] Further, a buffer layer is further included, and the buffer layer is arranged between the base and the inner wall of the sector ring for reducing the transmission of impact load.

[0015] Further, the detachable modular tooth sleeve device is made of wear-resistant alloy.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention splits the existing integrated spiral mechanism into a base and a detachable modular tooth sleeve device. The detachable modular tooth sleeve device is wrapped and installed on the base of the spiral mechanism. When the external teeth are worn and need to be replaced, only the detachable modular tooth sleeve device needs to be replaced, without replacing the whole spiral mechanism, thus reducing the replacement difficulty.

[0018] (2) The detachable modular tooth sleeve device of the present invention can be set into tooth sleeve devices with different central angles in combination with the setting of the external teeth, and has good versatility.

[0019] (3) The present invention is easy to disassemble and install, reduces the replacement time and difficulty, largely avoids material waste and reduces the cost. Description of the Drawings

[0026] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and the detailed implementation manners and specific operation processes are given, but the protection scope of the present invention is not limited to the following embodiments.

[0027] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is 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 construed as a limitation of the present invention. In addition, the terms "first", "second", "third", etc. are used to describe common objects, and only represent different instances referring to the same object, rather than implying that the objects described in this way must be in a given order, whether in time, space, sorting or any other way.

[0028] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0029] As Figure 2 and Figure 3 shown, in the existing integral spiral mechanism, there is a spiral blade 6 on the bearing 5, the spiral blade surrounds the bearing 5, and external teeth 23 are provided at the edge of the spiral blade 6, including large teeth and small teeth of different specifications. Since the existing spiral mechanism is integrally cast, during the process of conveying viscous materials such as desulfurized gypsum and limestone powder, it is easy to cause rapid wear on the tooth surface, affecting the use, and the whole spiral mechanism needs to be replaced. However, the overall replacement is difficult, costly, and difficult to maintain.

[0030] Therefore, this embodiment provides a detachable modular tooth sleeve device for the Eurobin screw mechanism. In this embodiment, the screw mechanism is decomposed into a base 1 and a detachable modular tooth sleeve device. The base 1 is modified from the original screw mechanism and is formed by grinding the edge of the screw blade 6. This split design makes the easily worn part of the screw mechanism a replaceable modular device, eliminating the need to replace the entire screw mechanism and solving the problems existing in the prior art.

[0031] Specifically, as Figure 1 and 5 shown, the device includes a tooth sleeve body 2 and bolt holes 3. The tooth sleeve body 2 includes symmetrically arranged fan rings 21, bow-shaped connectors 22 and external teeth 23. The bow-shaped connectors 22 are respectively connected to the outermost arc edges of the two fan rings 21, and the external teeth 23 are arranged on the bow-shaped connectors 22, thus forming a hollow structure inside for sleeving on the base 1. In this embodiment, the fan rings 21, bow-shaped connectors 22 and external teeth 23 are integrally designed with wear-resistant alloy. Wear-resistant alloy: such as high-chromium cast iron Cr26, and surface quenching is carried out to make it have the required hardness and wear resistance; or wear-resistant ceramic sheets with a thickness of 1 - 1.5 mm are installed on the surface. Multiple rows of bolt holes 3 are correspondingly arranged on the two fan rings 21, and multiple bolt holes 3 are provided in each row. As Figure 4 shown, in this embodiment, the bolt holes 3 are arranged in two rows every 60 degrees, and the central angle of the fan ring 21 is set to 120 degrees. With the device being 120 degrees and two groups of double-row bolt holes 3 being set every 60 degrees, it is convenient to install and disassemble the tooth sleeve every 120 degrees. And according to the large teeth with one every 40 degrees for a total of 9, each 120-degree module device can evenly distribute the number of teeth, making each section of the tooth sleeve the same, eliminating the need to design multiple tooth sleeve arrangements. To adapt to screw mechanisms with different structures, the central angle of the fan ring 21 in this embodiment can also be set to 60 degrees, 90 degrees or 180 degrees.

[0032] To reduce the transmission of impact load and extend the service life of the base 1, a buffer layer is also provided in this embodiment. The buffer layer is arranged between the base 1 and the inner wall of the fan ring 21.

[0033] To facilitate the replacement operation, positioning pin holes 4 are also provided at both ends of the fan ring 21 in this embodiment, which is convenient for circumferential positioning during replacement.

[0034] In summary, a detachable modular tooth sleeve device is obtained. Each device is used as a section and is installed on the base 1 through the bolt holes 3 and positioning pin holes 4. The design process of the device can be referred to as follows:

[0035] (1) Measure the parameters of the original screw conveyor mechanism and draw diagrams;

[0036] (2) Design a detachable modular tooth sleeve according to the parameters of the original base;

[0037] (3) Stop the equipment and grind and drill the original mechanism to the designed state;

[0038] (4) Install the gear sleeve modules one by one above the original base, fix them and install anti-loosening bolts.

[0039] (5) Start the equipment and observe whether the equipment runs normally and whether there is any looseness.

[0040] Although the preferred embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications to these embodiments once they know the basic creative concept. Therefore, the appended claims are intended to be construed as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0041] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
