Description

Technical Field

[0001] This utility model relates to the field of methylnaphthalene mixing technology, and in particular to a safe mixing equipment for the production of methylnaphthalene. Background Technology

[0002] Methylnaphthalene is a colorless, oily liquid with a naphthalene-like odor. It can evaporate with vapor, is flammable, insoluble in water, but readily soluble in ether and ethanol. During the production and processing of methylnaphthalene, mixing tanks are used to mix the methylnaphthalene raw materials.

[0003] When mixing methylnaphthalene raw materials in a mixing tank, a stirring rod is installed inside the mixing tank. The rotation of the stirring rod can stir the methylnaphthalene raw materials. Currently, most stirring rods are composed of multiple horizontal bars. However, the contact between the horizontal stirring rods and the methylnaphthalene raw materials is limited when the stirring rods rotate inside the mixing tank. This results in uneven mixing of the methylnaphthalene raw materials in the upper and lower layers. Furthermore, the methylnaphthalene raw materials are very easy to remain on the tank wall when the mixing tank rotates. It is impossible to ensure the cleanliness of the mixing tank in a timely manner during the mixing process. Utility Model Content

[0004] The purpose of this invention is to solve the problem of limited mixing degree of methylnaphthalene raw materials in the prior art, and to propose a safe mixing equipment for the production of methylnaphthalene.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A safe mixing device for the production of methylnaphthalene includes a base and a mixing tank for mixing methylnaphthalene. A connecting frame is fixedly installed on the mixing tank, and a support is fixedly installed on the base. A rotating shaft connected to the connecting frame and the mixing tank is rotatably installed on the support. A mesh plate for extruding methylnaphthalene is provided on the connecting frame via a moving part. A rotating structure for pulling the mixing tank to rotate is installed on the support.

[0007] Preferably, the moving part includes a motor fixedly installed on the connecting frame, and a bidirectional lead screw is fixedly connected to the output end of the motor. Two matching nuts are slidably sleeved on the bidirectional lead screw, and a ring frame is fixedly installed on the nuts. The mesh plate is disposed on the ring frame, and a support plate is fixedly installed on the mesh plate. A brush for cleaning the inner wall of the mixing tank is provided on the support plate.

[0008] Preferably, the bidirectional lead screw is horizontally arranged, and symmetrically arranged filter plates are fixedly installed on the mixing tank.

[0009] Preferably, a guide rod for guiding the ring frame is fixedly installed on the mixing tank, and the filter plate is vertically arranged on both sides of the mesh plate.

[0010] Preferably, the rotating structure includes an annular rack fixedly mounted on the mixing tank, a second motor fixedly mounted on the bracket, and a drive shaft that is connected to the annular rack for transmission at the output end of the second motor.

[0011] Preferably, the drive shaft is horizontally positioned below the mixing tank, and a gear that meshes with a ring rack is fixedly mounted on the drive shaft.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model supports the mixing tank with a bracket, so that the mixing tank is in a horizontal state. Under the traction of the ring rack and gear, the mixing tank rotates, thereby enabling the methylnaphthalene raw material to be fully stirred when the mixing tank rotates.

[0014] 2. This utility model provides a mesh plate inside the mixing tank. When the two mesh plates move towards each other, they can squeeze the methylnaphthalene raw material. When the mesh plate comes into contact with the filter plate, it can squeeze the methylnaphthalene again. At the same time, when the mesh plate moves, it drives the brush to clean the inner wall of the mixing tank, thereby ensuring the cleanliness of the mixing tank. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3A safe mixing device for the production of methylnaphthalene includes a base 1 and a mixing tank 3 for mixing methylnaphthalene. A connecting frame is fixedly installed on the mixing tank 3. A bracket 2 is fixedly installed on the base 1, and a rotating shaft 5 connected to the connecting frame and the mixing tank 3 is rotatably installed on the bracket 2. A mesh plate 9 for extruding methylnaphthalene is provided on the connecting frame through a moving part.

[0021] The moving part includes a motor 4 fixedly mounted on the connecting frame, and a bidirectional lead screw 6 fixedly connected to the output end of the motor 4. Two matching nuts 7 are slidably sleeved on the bidirectional lead screw 6, and a ring frame 8 is fixedly mounted on the nuts 7. A mesh plate 9 is set on the ring frame 8, and a support plate is fixedly mounted on the mesh plate 9. A brush 10 for cleaning the inner wall of the mixing tank 3 is provided on the support plate.

[0022] When the motor 4 is powered on, it drives the bidirectional lead screw 6 to rotate. When the bidirectional lead screw 6 rotates, it drives the two nuts 7 to move in opposite directions. When the two screen plates 9 move in opposite directions, they can squeeze the methylnaphthalene raw material. When the two nuts 7 move in opposite directions, they can squeeze the methylnaphthalene raw material between the screen plate 9 and the filter plate 11. When the methylnaphthalene raw material is squeezed in the mixing tank 3, it can be evenly separated.

[0023] The bidirectional lead screw 6 is horizontally set, and the mixing tank 3 is fixedly installed with symmetrically arranged filter plates 11. The mixing tank 3 is fixedly installed with guide rods for guiding the ring frame 8. The filter plates 11 are vertically set on both sides of the screen plate 9. By setting guide rods on the mixing tank 3, and the guide rods can limit the movement direction of the ring frame 8 and the nut 7, the screen plate 9 can drive the brush 10 to move and scrape the inner wall of the mixing tank 3, thereby maintaining the cleanliness of the mixing tank 3.

[0024] A rotating structure for pulling the mixing tank 3 to rotate is installed on the support 2.

[0025] The rotating structure includes an annular rack 12 fixedly mounted on the mixing tank 3, a second motor 13 fixedly mounted on the bracket 2, and a drive shaft 14 that is connected to the annular rack 12 via the output end of the second motor 13. The drive shaft 14 is horizontally positioned below the mixing tank 3, and a gear 15 that meshes with the annular rack 12 is fixedly mounted on the drive shaft 14. When the drive shaft 14 rotates, it drives the mixing tank 3 to rotate through the meshing gear 15 and the annular rack 12. The horizontally positioned mixing tank 3 ensures the degree of mixing of the methylnaphthalene raw material.

[0026] It should be noted that the specific model and specifications of motor 4 and motor 13 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0027] The functional principle of this utility model can be explained through the following operation methods:

[0028] Add the methylnaphthalene raw material into mixing tank 3;

[0029] The output end of motor 4 drives the bidirectional lead screw 6 to rotate. When the bidirectional lead screw 6 rotates, it drives the two nuts 7 to move in opposite directions.

[0030] When the two nuts 7 move toward each other, they drive the ring frame 8 to move synchronously. The ring frame 8 drives the two mesh plates 9 to move relative to each other. When the mesh plates 9 move, they squeeze the methylnaphthalene raw material.

[0031] When the two nuts 7 move in opposite directions, they drive the ring frame 8 to move synchronously. The ring frame 8 drives the screen plate 9 to gradually approach the filter plate 11. When the screen plate 9 and the filter plate 11 are in contact with each other, the methylnaphthalene raw material is squeezed. When the screen plate 9 moves, it drives the ring frame 8 and the brush 10 to move synchronously, so that the brush 10 can scrape the inner wall of the mixing tank 3.

[0032] At the same time, the output end of motor 13 drives the drive shaft 14 to rotate, the drive shaft 14 drives the gear 15 to rotate the meshing ring rack 12, so that the ring rack 12 drives the mixing barrel 3 to rotate, and the mixing barrel 3 drives the rotating shaft 5 to rotate on the support 2, which can thoroughly stir the methylnaphthalene in the mixing barrel 3.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
