Description

Technical Field

[0001] The present application relates to the technical field of screw stirring, and in particular to a screw stirring device. Background Art

[0002] Screw mixers are used to mix, stir, and process fluids or viscous materials. They typically utilize the rotating motion of the screw to achieve uniform mixing of materials and are widely used in the chemical, pharmaceutical, food, and building materials industries.

[0003] When conventional screw mixing equipment is used to feed viscous materials, in order to prevent problems such as stratification and separation of the viscous materials during transportation, a screw conveyor is usually sealed and connected to the feed port of the mixing equipment. The screw conveyor ensures that the materials are quickly and continuously fed into the mixing equipment.

[0004] However, when the viscous material enters the mixing equipment from the screw conveyor, some of the material will stick to the inner wall of the connecting pipe between the two, which will reduce the flow rate of the pipe over time. At this time, the staff will need to dismantle and relocate the screw conveyor and then clean the pipe, which will require more time and manpower costs for cleaning and maintenance, increasing the operating and maintenance costs. Therefore, it is necessary to provide a screw mixing equipment to solve the above problems.

[0005] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Summary of the Invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by this application is: to provide a screw mixing equipment, which does not require staff to disassemble and shift the screw conveyor as a whole, saving time and labor costs and reducing operation and maintenance costs.

[0012] A base plate is installed on the transmission pipe, a slot is provided through the base plate, the slot corresponds to the opening, a matching plate is installed on the outside of the slot, a protective sleeve is hinged on one side of the base plate, and the protective sleeve cooperates with the matching plate.

[0013] Furthermore, an extension strip is fixedly installed on the side of the protective sleeve away from the transmission tube, and two sets of locking mechanisms are provided on the base plate. The locking mechanism has a threaded rod hinged to the base plate, and the threaded rod is located on the side of the protective sleeve that is not hinged. A slot is provided at one end of the extension strip close to the threaded rod, and the slot corresponds to the threaded rod.

[0014] Furthermore, a turntable is threadedly connected to the threaded rod, and a gasket is fixedly installed on a side of the turntable close to the transmission pipe.

[0015] Furthermore, a rubber pad is provided between the bottom plate and the transmission pipe, and a sealing pad is fixedly installed on the inner wall of the protective sleeve.

[0016] Furthermore, the lower end pipe of the spiral mixer is connected to a discharge pipe.

[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0032] like Figure 1 As shown, the present application provides a screw mixing device, including a spiral mixer 1 for uniformly mixing viscous materials, a fixing frame 11 is fixedly installed below the spiral mixer 1, and the fixing frame 11 supports the spiral mixer 1, thereby improving the mixing stability;

[0033] At the same time, a feed port is provided at the upper end of the spiral mixer 1, and a transmission pipe 2 is connected to the upper pipe of the feed port. The viscous material to be mixed is added to the spiral mixer 1 through the transmission pipe 2, and the lower end pipe of the spiral mixer 1 is connected to a discharge pipe 12, which is used to discharge the evenly mixed viscous material to the outside.

[0034] In addition, the upper end pipe of the transmission pipe 2 is connected to a screw conveyor 4, which is a prior art and is used to transport viscous materials to the transmission pipe 2. The screw conveyor 4 is arranged on one side of the spiral mixer 1, and the lower end pipe of the screw conveyor 4 is connected to a feed hopper 41. The lower end of the feed hopper 41 is fixedly installed with a bracket 42, and the feed hopper 41 is fixed by the bracket 42, so that the viscous material is conveniently poured into the feed hopper 41.

[0035] like Figure 2-Figure 3 As shown, in order to prevent viscous materials from sticking to the inner wall of the transmission pipe 2, an opening 21 is opened on one side of the transmission pipe 2, and a protective mechanism 3 is installed on the outside of the opening 21. The protective mechanism 3 has a bottom plate 31, and the bottom plate 31 is fixedly installed on the transmission pipe 2 by bolts. In this application, a rubber pad is padded between the bottom plate 31 and the transmission pipe 2 to improve the sealing performance of the connection between the bottom plate 31 and the transmission pipe 2.

[0036] At the same time, a slot (not marked in the figure) is opened through the bottom plate 31, which corresponds to the opening 21. A matching plate 32 is fixedly installed on the outside of the slot, and a protective sleeve 33 is hinged on one side of the bottom plate 31. The protective sleeve 33 cooperates with the matching plate 32. In this application, a sealing gasket is fixedly installed on the inner wall of the protective sleeve 33. Therefore, when the protective sleeve 33 is sleeved on the matching plate 32, the sealing of the sleeve can be ensured by the sealing gasket.

[0037] In addition, an extension bar 34 is fixedly installed on the side of the protective cover 33 away from the transmission tube 2, and the protective cover 33 can be opened or closed conveniently by holding the extension bar 34;

[0038] To prevent the protective cover 33 from accidentally opening due to a touch, two sets of locking mechanisms 5 are provided on the bottom plate 31. The locking mechanisms 5 include a threaded rod 51 hinged to the bottom plate 31. The threaded rod 51 is located on the side of the protective cover 33 that is not hinged. A locking groove 35 is formed on the end of the extension bar 34 near the threaded rod 51. The locking groove 35 corresponds to the threaded rod 51.

[0039] At the same time, a turntable 52 is threadedly connected to the threaded rod 51 , and a gasket 53 is fixedly installed on a side of the turntable 52 close to the transmission pipe 2 .

[0040] To summarize: when closing the protective cover 33, first place the protective cover 33 on the mating plate 32, then rotate the threaded rod 51 and snap it into the slot 35, and rotate the turntable 52 to make the gasket 53 fit tightly against the extension bar 34 until it cannot rotate, thereby fixing the protective cover 33 to prevent accidental opening.

[0041] When the transmission pipe 2 needs to be cleaned, the operator first rotates the turntable 52 outward and loosens it to keep it away from the protective sleeve 33, then rotates the threaded rod 51 outward to disengage it from the slot 35, and then opens the protective sleeve 33 through the extension bar 34, thereby cleaning the inner wall of the transmission pipe 2 through the opening 21. Therefore, when cleaning the transmission pipe 2, there is no need for the staff to disassemble and shift the screw conveyor 4 as a whole, saving time and labor costs and reducing operation and maintenance costs.

[0042] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
