Description

Technical Field

[0001] The utility model relates to the technical field of flux production equipment, in particular to a mixing equipment with a cooling structure. Background Art

[0002] Flux is usually a mixture with rosin as the main ingredient. It is an auxiliary material to ensure the smooth progress of the welding process. Its main function is to remove oxides on the welding surface, prevent re-oxidation of the solder and the welding surface during welding, reduce the surface tension of the solder, and make the metal surface reach the necessary cleanliness. When processing the flux, it is often necessary to mix and stir the raw materials of the flux, and a stirring device is required during the mixing and stirring process.

[0003] According to a publicly disclosed environmentally friendly integrated circuit flux production batching device (Announcement No.: CN217989099U), the above application provides a mixing barrel that can mix the raw material powders added with cold water, and a cooling jacket that can ensure that the raw materials remain at a low temperature during the mixing process to avoid the generation of harmful gases from the rosin due to excessive temperature.

[0004] However, in actual use of the above equipment, when the raw materials are mixed and stirred, the heat in the raw materials will be more concentrated in the internal center of the raw materials. At this time, when the flux raw materials are cooled by the cooling jacket, only the outside of the raw materials can be cooled, resulting in the increase of the heat accumulation temperature inside the raw materials, causing the rosin to produce toxic gases when heated, affecting the cooling effect of the raw materials. In view of this, we propose a mixing equipment with a cooling structure. Utility Model Content

[0005] The purpose of the utility model is to provide a mixing device with a cooling structure to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a mixing device with a cooling structure, comprising a mixing barrel, a motor is fixedly installed on the top of the mixing barrel, a discharge pipe is fixedly installed at the center of the right side of the mixing barrel, a cold water tank is arranged on the left side of the mixing barrel, and a cooling component is arranged inside the mixing barrel, and the cooling component comprises:

A spring is fixedly mounted on the inner top surface of the fixed cylinder, and a limit plate is fixedly mounted on the bottom end of the spring. When the limit plate moves toward the spring, the spring can be squeezed, so that the spring is compressed to generate elastic potential energy, and a main stirring rod is fixedly mounted on the bottom end of the limit plate;

[0009] A lifting chamber is provided in the bottom inner wall of the mixing barrel, a lifting hydraulic cylinder is fixedly installed on the inner bottom surface of the lifting chamber, and a moving cylinder is fixedly installed on the top end of the lifting hydraulic cylinder.

[0010] Preferably, the bottom end of the main stirring rod passes through the fixed cylinder, the outer wall of the limiting plate is in contact with the inner wall of the fixed cylinder, and the limiting plate is arranged in a rectangular structure. When the fixed cylinder rotates, the main stirring rod can be driven to rotate synchronously through the limiting plate.

[0011] Preferably, the top end of the movable cylinder passes through the lifting cavity, and the upper surface of the movable cylinder fits with the bottom surface of the inner wall of the mixing barrel. When the lifting hydraulic cylinder is started, the movable cylinder can be driven to perform linear motion in the up and down directions.

[0015] Compared with the prior art, the utility model provides a mixing device with a cooling structure, which has the following beneficial effects:

[0016] 1. The mixing equipment with a cooling structure can mix and stir the center and side of the flux raw material in the mixing barrel synchronously through the cooperation of the rotating ring frame, the side stirring rod, the fixed cylinder, the spring, the limit plate and the main stirring rod. At the same time, through the cooperation of the lifting chamber, the lifting hydraulic cylinder and the moving cylinder, the thickness of the raw material can be reduced, so that the raw material can better exchange heat with the cold water in the annular cavity and the moving cylinder, avoiding heat accumulation inside the raw material. The cold water inside the annular cavity can only cool down the outside of the raw material. The inside of the raw material is still in a high temperature state, so that the rosin is heated to produce toxic gas. At the same time, when the raw material enters the gap between the moving cylinder and the inner wall of the mixing barrel, the side stirring rod can still mix and stir the raw material, thereby accelerating the cooling efficiency of the raw material.

[0017] 2.

The provided cone can reduce the resistance when the moving cylinder moves upward, and allow the raw materials to flow better to the outside of the moving cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a mixing device with a cooling structure, comprising a mixing barrel 1, a feed port is fixedly installed at the top of the mixing barrel 1, a motor 2 is fixedly installed at the top of the mixing barrel 1, a discharge pipe 3 is fixedly installed at the right center of the mixing barrel 1, an annular cavity is opened in the inner wall of the upper end of the mixing barrel 1, the interior of the annular cavity is connected with the interior of a cold water tank 4 through a pipeline, the interior of a moving cylinder 509 is connected with the interior of the cold water tank 4 through a telescopic hose, a plurality of water pumps are arranged inside the cold water tank 4, one end of which is connected to cold water, and the other end is connected to a pipeline or a telescopic hose, so that cold water can be injected into and replaced in the annular cavity and the interior of the moving cylinder 509, and the raw materials mixed in the mixing barrel 1 can be cooled when the cold water enters the annular cavity, a cold water tank 4 is arranged on the left side of the mixing barrel 1, and a cooling component is arranged inside the mixing barrel 1.

[0024] The cooling assembly includes: a rotating ring frame 501, a fixed cylinder 503 and a lifting chamber 507. The rotating ring frame 501 is arranged at the inner top end of the mixing barrel 1. A side stirring rod 502 is fixedly installed at the outer circle of the bottom surface of the rotating ring frame 501. The fixed cylinder 503 is fixedly installed at the center of the bottom surface of the rotating ring frame 501. A spring 504 is fixedly installed on the inner top surface of the fixed cylinder 503. A limiting plate 505 is fixedly installed on the bottom end of the spring 504. The outer wall of the limiting plate 505 is in contact with the inner wall of the fixed cylinder 503. The limiting plate 505 is arranged in a rectangular block structure. The inner wall of the fixed cylinder 503 can guide and limit the movement of the limiting plate 505, so that the limiting plate 505 can only perform linear motion in the up and down directions. The bottom end of the limiting plate 505 is fixedly installed with a main stirring rod 506, and the bottom end of the main stirring rod 506 passes through the fixed cylinder 503.

[0025] When the motor 2 starts to drive the rotating ring frame 501 to rotate, it can drive the side stirring rod 502 and the main stirring rod 506 to move synchronously. The side stirring rod 502 can stir and mix the raw materials located on the outside of the mixing barrel 1, and the main stirring rod 506 can stir and mix the raw materials located in the center. The shape of the bottom end of the main stirring rod 506 is adapted to the size of the top end of the cone 603.

[0026] The lifting chamber 507 is opened in the bottom inner wall of the mixing barrel 1, and a lifting hydraulic cylinder 508 is fixedly installed on the inner bottom surface of the lifting chamber 507. A moving cylinder 509 is fixedly installed on the top of the lifting hydraulic cylinder 508. The top of the moving cylinder 509 passes through the lifting chamber 507, and the upper surface of the moving cylinder 509 is in contact with the bottom surface of the inner wall of the mixing barrel 1. When the lifting hydraulic cylinder 508 is started, it can drive the moving cylinder 509 to move linearly in the up and down directions.

[0027] A temperature control detector can be set inside the mixing barrel 1. When it is detected that there is serious heat accumulation inside the mixed raw materials, the lifting hydraulic cylinder 508 can be started to drive the moving cylinder 509 to move upward, push and squeeze the raw materials, so that the raw materials are distributed between the moving cylinder 509 and the inner wall of the mixing barrel 1, and the thickness of the material is reduced. At this time, the raw materials can be cooled by the cold water inside the annular cavity and the moving cylinder 509 to avoid heat accumulation inside the raw materials, resulting in only the cold water inside the annular cavity to cool the outside of the raw materials, while the inside of the raw materials is still in a high temperature state, causing the rosin to produce toxic gases due to the heat.

[0028] During the upward movement of the movable cylinder 509, the main stirring rod 506 will be squeezed, so that the main stirring rod 506 moves upward under the guide limit of the limit plate 505, and the spring 504 is squeezed to prevent the main stirring rod 506 from affecting the upward movement of the movable cylinder 509. At the same time, when the raw materials enter the gap between the movable cylinder 509 and the mixing barrel 1, the motor 2 can still be started to drive the side stirring rod 502 to rotate, so as to mix and stir the raw materials in the gap and accelerate the cooling efficiency.

[0029] A cylinder 601 is provided inside the movable cylinder 509, and support rods 602 are fixedly installed at the upper and lower ends of the cylinder 601. The end of the support rod 602 away from the cylinder 601 is fixedly connected to the inner wall of the movable cylinder 509. The cylinder 601 and the support rod 602 can limit the internal space of the movable cylinder 509, so that when the cold water enters the movable cylinder 509, it can better fit the inner wall of the movable cylinder 509, thereby obtaining better heat exchange efficiency with the raw materials. A cone 603 is fixedly installed on the upper surface of the movable cylinder 509. When the movable cylinder 509 moves upward, the cone 603 can break the raw materials well, so that the raw materials flow along the inclined surface of the cone 603 to the outside of the movable cylinder 509, thereby reducing the load of the lifting hydraulic cylinder 508 and extending the service life of the lifting hydraulic cylinder 508.

[0030] In the utility model, when in use, the water pump is started to draw cold water in the cold water tank 4 into the annular cavity and the movable cylinder 509, the raw materials are added into the interior of the mixing barrel 1, and the motor 2 is started to drive the side stirring rod 502 and the main stirring rod 506 to rotate to stir and mix the raw materials. When it is detected that the heat accumulation inside the raw materials is serious during the stirring process, the lifting hydraulic cylinder 508 can be started to drive the movable cylinder 509 to move upward, and the cone 603 will break the raw materials and make the raw materials flow to the outside of the movable cylinder 509, so that the raw materials enter the inner wall of the movable cylinder 509 and the mixing barrel 1, reduce the thickness of the raw materials, and make the raw materials better exchange heat with the cold water inside the annular cavity and the movable cylinder 509, avoid cooling only by the cold water inside the annular cavity, which easily causes heat to accumulate inside the raw materials and affect the cooling efficiency. When the raw materials enter the gap between the movable cylinder 509 and the inner wall of the mixing barrel 1, the motor 2 can continue to be started to drive the side stirring rod 502 to rotate, mix the raw materials in the gap, and speed up the cooling efficiency.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
