Description

Technical Field

[0001] The utility model relates to the technical field of mixed emulsification, in particular to mixed emulsification equipment for preparing an oil-proofing agent. Background Art

[0002] Oil-proof agent is an auxiliary agent, mainly used to prevent the surface of fabrics from being stained by oil substances. It can be used in the paper sizing process to form oil-proof paper by adsorption and precipitation on the fiber surface.

[0003] In the production process of oil-proof agent, oil-proof agent mixed emulsification mainly refers to mixing oil-proof agent with other substances to form a uniform emulsion-like substance through emulsification. This emulsifier is an important component of oil-proof agent. It can emulsify oil substances and water to form an emulsion-like substance. This emulsion-like substance can effectively prevent oil substances from adhering to the surface of fabrics, thereby achieving the purpose of oil repellency.

[0004] In the process of mixing and emulsifying the oil-proofing agent, emulsifying equipment is needed. There are many types of these equipment, such as pipeline emulsifiers, high shear emulsifiers, kettle emulsifiers and emulsifying tanks. The main function of these equipment is to mix and emulsify the oil-proofing agent and other raw materials through mechanical force to form a uniform emulsion-like substance. For example, in the patent document with patent publication number CN218901709U, a mixed emulsifying equipment for preparing waterproof and oil-proofing agents is disclosed, and its main structure includes an emulsifying tank, a tank cover, a motor, a feed pipe, an emulsifying vertical stirring shaft, a discharge pipe, a discharge valve, a support leg, a chassis, a support frame, a rotatable sampling tube structure, an electric lifting frame structure and a detachable adhesive plate structure. The upper end of the emulsifying tank is bolted to the tank cover, the middle part of the upper side of the tank cover is bolted to the motor, the upper right side of the tank cover is integrated with a feed pipe, and the lower end of the output shaft of the motor is bolted to the emulsifying vertical stirring shaft; the lower middle part of the emulsifying tank is integrated with a discharge pipe and other components.

[0005] It can be seen from the above structure that it mainly separates the emulsification tank and the tank cover, connects the external power supply to the electric push rod, and the electric push rod drives the lifting frame and the connecting rod to move upward, thereby opening the tank cover to facilitate the inspection of the inside of the emulsification tank. When the tank cover is raised or lowered, the limit rod moves along the limit seat to play a limiting role.

[0006] However, this structure can only realize the vertical displacement of the tank cover during the actual emulsification process. However, after the displacement, it usually still causes certain interference to the feeding, cleaning and maintenance steps of the emulsification tank, and the separation and displacement effect of the tank body and the tank cover is poor. In addition, the existing equipment also has the problem of relatively low emulsification efficiency and poor emulsification effect caused by single-axis mechanical operation during emulsification operation.

[0028] The following is a detailed description of the embodiments of the technical solution of the utility model in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. Figure 1-Figure 4 as shown in .

[0029] Embodiment 1: A mixed emulsification equipment for preparing oil-proofing agent, comprising two symmetrically arranged emulsification tank groups, a tank cover shifting opening and closing mechanism is arranged between the two emulsification tank groups, and the left and right sides of the top of the tank cover shifting opening and closing mechanism are respectively fixedly connected to the outer side wall of the tank cover 1 of the emulsification tank group at the corresponding position; the emulsification tank group comprises an emulsification tank body 2 fixedly installed on the ground, the tank cover 1 is sealed and fitted on the top of the emulsification tank body 2, and a mixing agitator is installed inside the mixing emulsification chamber 3 of the emulsification tank body 2, the top of the mixing agitator movably and sealably passes through the central through hole of the tank cover 1 and extends above it to connect with a stirring driving member, and the top of the stirring driving member is fixedly connected to a stirring lifting mechanism. A discharge pipe 4 with a valve is installed at the lower part of each emulsification tank body 2, and a feed pipe opening 5 with a cover is installed on the top of each tank cover 1. The oil-proofing agent preparation mixed emulsification equipment is mainly used for the mixed stirring emulsification operation in the oil-proofing agent production process. By feeding the material into the mixed emulsification chamber 3 of the emulsification tank group in advance, after the feeding is completed, the stirring drive can be started to cooperate with the reciprocating lifting movement of the stirring lifting mechanism to drive the mixing agitator to complete the rapid stirring and mixing of the internal solution in the mixed emulsification chamber 3 to achieve emulsification. During the stirring process, a compound movement of fixed-axis stirring and up and down displacement can be achieved to improve the effect and efficiency of mixed emulsification. When the emulsification mixing operation is completed, the internal emulsified product can be discharged by controlling the opening of the discharge pipe 4. During the discharge process, the discharge pipe 4 can be connected to the external power pump pipe as needed to improve the discharge effect.

[0030] When the discharge is completed and the inside of the emulsification tank body 2 needs to be deeply cleaned or inspected, the tank cover switching opening and closing mechanism is controlled to be raised and lowered first, so that the bottom of the mixing agitator is higher than the top of the emulsification tank body 2, and then the high-torque rotary motor 7 on the tank cover switching opening and closing mechanism is controlled to complete the rotation and drive the tank covers 1 on both sides to rotate and move as needed, thereby achieving the purpose of exposing the top opening of the emulsification tank body 2 and ensuring the convenience of deep cleaning and inspection.

[0031] In any of the above schemes, it is preferred that the tank cover repositioning opening and closing mechanism includes a multi-stage lifting cylinder 6 fixedly installed on the ground between the two emulsification tank bodies 2, a large torque rotating motor 7 is fixedly installed on the top piston rod of the multi-stage lifting cylinder 6, and a U-shaped connecting frame 8 is fixedly installed on the top of the motor shaft of the large torque rotating motor 7, the tops of the two vertical sections of the U-shaped connecting frame 8 are fixedly connected to the middle section of a horizontally arranged support beam 9 through threaded connectors, and the left and right ends of the support beam 9 are fixedly installed on the outer side wall of the tank cover 1 at corresponding positions.

[0032] It should be noted that when the tank cover repositioning and opening and closing mechanism is working, the multi-stage lifting of the multi-stage lifting cylinder 6 at the bottom can drive the corresponding rotating motor and the U-shaped connecting frame 8 on the top to follow the lifting, and realize the locking positioning after completing the lifting into place. At this time, the rotation of the rotating motor can drive the corresponding U-shaped connecting frame 8, the support beam 9 and the tank cover 1 at both ends to rotate into place. When it is rotated into place, the top openings of the two emulsification tank bodies 2 at the bottom can be vacated to facilitate deep cleaning and maintenance of the inside of the emulsification tank body 2.

[0033] Among them, the multi-stage lifting cylinder 6 is preferably a multi-stage telescopic oil cylinder, and a matching hydraulic station is configured to provide power for it.

[0034] In any of the above solutions, it is preferred that the stirring drive member includes a vertically arranged stirring motor 10, and the bottom of the motor shaft of the stirring motor 10 is coaxially fixedly connected to the top of the mixing agitator.

[0035] The rotation speed of the stirring motor 10 can be controlled as needed when rotating, effectively ensuring that the required stirring effect is achieved when mixing and stirring the materials.

[0036] In any of the above schemes, it is preferred that the stirring and lifting mechanism includes two synchronous lifting electric cylinders 11 symmetrically arranged on both sides of the stirring motor 10, the bottoms of the cylinder barrels of the two synchronous lifting electric cylinders 11 are fixedly installed on the top of the tank cover 1, and the tops of the piston rods of the two synchronous lifting electric cylinders 11 are fixedly connected to a horizontally arranged lifting plate 12, and the stirring motor 10 is fixedly installed at the bottom center of the lifting plate 12.

[0037] The function of the stirring and lifting mechanism is to drive the stirring motor 10 to realize lifting and lowering control in the height direction. When the stirring motor 10 is driven to lift and lower, the entire mixing agitator at the bottom connected to the stirring motor 10 can be linked to follow and lift and lower, thereby achieving the stirring effect of the mixing agitator in the working state when stirring and emulsifying the solution inside the emulsification tank body 2. At the same time, during the stirring process, the stirring effect and comprehensiveness of the stirring can be improved by stirring and rotating while lifting and lowering.

[0038] In any of the above schemes, it is preferred that the mixing agitator includes a vertical stirring shaft 13 vertically arranged in the center of the mixing and emulsification chamber 3, the top of the vertical stirring shaft 13 movably passes through the central through hole of the tank cover 1 and extends above it to be fixedly connected to the motor shaft of the stirring motor 10, a positioning sleeve 14 is fixedly installed on the lower outer wall of the vertical stirring shaft 13, and horizontal stirring rods 15 are respectively fixedly welded on the outer walls on both sides of the positioning sleeve 14, and a stirring blade 16 is integrally formed at the outer end of each of the horizontal stirring rods 15.

[0039] It should be noted that when the mixing agitator is working, the upper stirring motor 10 provides a rotational driving force. When the vertical stirring shaft 13 is subjected to the rotational driving force, the horizontal stirring rod 15 and the stirring blade 16 at the bottom thereof will be driven to rotate accordingly, thereby achieving the purpose of quickly completing the stirring. The stirring blade 16 arranged here adopts a double-blade structure with both the upper and lower parts extending outward, which can achieve a better stirring effect during stirring.

[0040] Embodiment 2: Compared with Embodiment 1, this embodiment is different in that it also includes the following technical features:

[0041] Each of the stirring blades 16 is vertically arranged and has a cutting grid 17 at its center. The cutting grid 17 in a rotating state is used to cut the bubbles generated in the emulsified solution of the oil repellent.

[0042] During the rotation of each stirring blade 16 , bubbles are generated in the internal emulsion. The operation of the cutting grid 17 can quickly cut the generated bubbles, thereby reducing the number of bubbles and effectively ensuring the homogeneity and quality of the emulsified solution.

[0043] In any of the above schemes, preferably, a U-shaped scraper plate 18 is fixedly installed on the top of the vertical stirring shaft 13 , and outer sides of two vertical sections of the U-shaped scraper plate 18 are both in contact with the inner wall of the mixing and emulsification chamber 3 .

[0044] It should be noted that the U-shaped scraper plate 18 provided here is installed at the bottom of the vertical stirring shaft 13 in a quick-release manner. After the installation is completed, the U-shaped scraper plate 18 follows the rotation of the vertical stirring shaft 13 to complete the cleaning and scraping of the inner wall of the mixing and emulsification chamber 3, thereby ensuring the cleanliness of the inner wall of the mixing and emulsification chamber 3.

[0045] Embodiment 3: Compared with Embodiment 2, this embodiment is different in that it also includes the following technical features:

[0046] In any of the above schemes, it is preferred that mist air nozzles 19 are installed on both side walls of the lower part of the mixing and emulsification chamber 3 of each emulsification tank body 2, and the outer end pipe joints 20 of each mist air nozzle 19 are sealed and extended to the outside of the emulsification tank body 2 and are used to connect to the external air source pipeline in the working state.

[0047] It should be noted that: by opening each mist jet nozzle 19, the external sterile airflow can be sprayed into the mixing and emulsification chamber 3 of the emulsification tank body 2, thereby achieving pneumatic mixing and effectively ensuring the effect of mixing and emulsification.

[0048] Specific working principle: The oil-proofing agent preparation mixing emulsification equipment in the utility model is mainly used for the mixing, stirring and emulsification operation in the oil-proofing agent production process. By pre-feeding into the mixing emulsification chamber 3 of the emulsification tank group, after the feeding is completed, the mixing agitator can be driven by starting the stirring drive member to cooperate with the reciprocating lifting motion of the stirring lifting mechanism to complete the rapid stirring and mixing of the internal solution in the mixing emulsification chamber 3 to achieve emulsification.

[0049] During the stirring process, a compound motion of fixed-axis stirring and simultaneous up-and-down displacement can be achieved, thereby improving the effect and efficiency of mixing and emulsification.

[0050] When the emulsification and mixing operation is completed, the internal emulsified product can be discharged by controlling the opening of the discharge pipe 4. During the discharge process, the discharge pipe 4 can be connected to the external power pump pipe as needed to improve the discharge effect. When the discharge is completed, if the inside of the emulsification tank body 2 needs to be deeply cleaned or repaired, the tank cover transposition opening and closing mechanism is controlled to be raised and lowered in place first, so that the bottom of the mixing agitator is higher than the top of the emulsification tank body 2.

[0051] Then the high-torque rotary motor 7 on the tank cover transposition opening and closing mechanism is controlled to complete the rotation and drive the tank covers 1 on both sides to rotate and move as needed, thereby achieving the purpose of exposing the top opening of the emulsification tank body 2 and ensuring the convenience of deep cleaning and maintenance.

[0052] From the above, it can be seen that the synchronous operation of two emulsification tank groups can realize the rapid stirring, mixing and emulsification treatment of the oil-proof agent emulsification process; at the same time, relying on the movement of the tank cover transposition opening and closing mechanism at the center of the connection line of the two emulsification tank groups, it can achieve smoothness when it is necessary to open the tank cover 1 for deep cleaning of the inside of the emulsification tank body 2, so as to facilitate timely maintenance of the situation inside the tank.

[0053] When the can cover transposition opening and closing mechanism drives the filling cover to rotate, the can cover 1 is symmetrically connected on both sides, which can ensure the balance control on both sides during the rotation process, ensure the stability of the rotation control position, and reduce the risk of rollover.

[0054] When the tank cover transposition opening and closing mechanism is shifting the two tank covers 1, the central rotation is used to drive the tank covers 1 symmetrical on both sides to rotate, so that they can be rotated into place; at the same time, after the rotation and transposition, the tank cover 1 will not interfere with or block the bottom of the emulsification tank body 2, effectively ensuring the smoothness of irrigation and movement; when the internal solution is mixed inside the emulsification tank body 2, a mixing agitator is used to quickly complete the mixing operation, and at the same time, the thick emulsion adhered to the inner wall of the mixing emulsification chamber 3 can be scraped, and synchronous stirring can be achieved under the upper and lower control states during the mixing process, thereby improving the emulsification efficiency and effect.

[0055] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
