Description

Technical Field

[0001] This utility model relates to the field of defoamer production technology, and in particular to an emulsification and dispersion kettle for defoamer production. Background Technology

[0002] Defoamers reduce the surface tension of water, solutions, suspensions, etc., preventing foam formation or reducing or eliminating existing foam. However, defoamers often require the use of emulsification reactors, which have some drawbacks, such as:

[0003] Ordinary emulsification and dispersion kettles cannot self-clean during use, which makes it easy for materials to remain on the internal parts of the device, resulting in waste of raw materials and incomplete emulsification and dispersion, which is detrimental to the use of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide an emulsification and dispersion reactor for the production of defoamers, so as to solve the problems mentioned in the background art.

[0005] An emulsification and dispersion vessel for defoamer production includes a vessel body, a vessel lid, and a feed hopper.

[0006] The upper end of the vessel body is provided with a vessel lid, and the interior of the vessel body is provided with an emulsification and dispersion mechanism. The upper end of the vessel lid is provided with a feed hopper, and the lower center of the vessel body is provided with a discharge valve. The emulsification and dispersion mechanism includes a motor, a stirring shaft, and a stirring rod. The motor is located at the center of the vessel lid, and the lower end of the motor is provided with a stirring shaft located inside the vessel body. The stirring shaft has stirring rods arranged at equal angles on its side. The lower end of the stirring shaft is provided with a friction ring, and the inner side of the friction ring is provided with a connecting shaft, which is rotatably located inside the stirring shaft. The bottom of the connecting shaft is provided with a cleaning rod, which fits against the bottom of the vessel body. A fixing groove is opened inside the side of the vessel body, and a piston rod is slidably arranged in the fixing groove. A return spring is provided inside the fixing groove. The vessel body and the vessel lid are fixed together by bolts, and the upper end of the vessel body and the bottom of the vessel lid are arc-shaped.

[0007] When the device is in use, the material is fed through the feed hopper, processed by the emulsification and dispersion mechanism, and discharged through the discharge valve after processing.

[0008] When the device is in use, the electric motor drives the stirring shaft and stirring rod to rotate. When the stirring rod rotates, it emulsifies and disperses the material.

[0009] The friction ring is in contact with the stirring shaft and the connecting shaft on both sides, respectively. So when the stirring shaft rotates, it will drive the connecting shaft to rotate through friction. When the connecting shaft is subjected to resistance, the rotation speed of the connecting shaft will be significantly lower than that of the stirring shaft, thus avoiding the phenomenon that the stirring shaft cannot rotate normally.

[0010] When the device is in use, the cleaning rod will rotate. Since the cleaning rod is in contact with the bottom of the vessel, the cleaning rod will continuously clean the vessel, thereby preventing the material from sticking to the vessel.

[0011] When the cleaning rod rotates and contacts the piston rod, the resistance on the cleaning rod will suddenly increase. At the same time, the piston rod will move inward under the thrust, and the rotational resistance of the cleaning rod will decrease. When the impact occurs, the cleaning rod, stirring shaft and stirring rod will vibrate, thereby preventing the material from sticking to the surface of the cleaning rod, stirring shaft and stirring rod, achieving a self-cleaning effect. Afterwards, the return spring will push the piston rod back to its original position.

[0012] When the device is in use, the vessel body and lid are fixed by bolts, and the vessel body can be opened or closed by removing the bolts.

[0013] The beneficial effects of this utility model are:

[0014] 1. When the device is in use, the stirring rod will emulsify and disperse the material, and the cleaning rod will be used to clean the device. Since the rotation speed of the cleaning rod is significantly lower than that of the stirring rod, the emulsification and dispersion will not be affected.

[0015] 2. When the cleaning rod rotates and cleans, it will continuously collide with the piston rod, causing the cleaning rod and the stirring rod to vibrate. This will prevent the material from sticking to the surface of the cleaning rod and the stirring rod, thus achieving self-cleaning of the device. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In practical implementation: such as Figure 1-5 As shown, an emulsification and dispersion reactor for defoamer production includes a reactor body 1, a reactor cover 2, and a feed hopper 3.

[0025] The upper end of the vessel body 1 is provided with a vessel cover 2, the interior of the vessel body 1 is provided with an emulsification and dispersion mechanism, the upper end of the vessel cover 2 is provided with a feed hopper 3, and the lower end of the vessel body 1 is provided with a discharge valve 12.

[0026] When the device is in use, it is fed through the feed hopper 3, processed by the emulsification and dispersion mechanism, and discharged through the discharge valve 12 after processing.

[0027] The emulsification and dispersion mechanism includes a motor 4, a stirring shaft 5, and a stirring rod 6. The motor 4 is located at the center of the vessel cover 2. The stirring shaft 5 is located at the lower end of the motor 4 and is located inside the vessel body 1. The stirring rod 6 is arranged at equal angles on the side of the stirring shaft 5.

[0028] When the device is in use, the electric motor 4 drives the stirring shaft 5 and the stirring rod 6 to rotate. When the stirring rod 6 rotates, it emulsifies and disperses the material.

[0029] A friction ring 7 is provided inside the lower end of the stirring shaft 5, and a connecting shaft 8 is provided inside the friction ring 7. The connecting shaft 8 is rotatably located inside the stirring shaft 5.

[0030] The friction ring 7 is attached to the stirring shaft 5 and the connecting shaft 8 on both sides respectively. So when the stirring shaft 5 rotates, it will drive the connecting shaft 8 to rotate through friction. When the connecting shaft 8 is subjected to resistance, the rotation speed of the connecting shaft 8 will be significantly lower than the rotation speed of the stirring shaft 5, thereby avoiding the phenomenon that the stirring shaft 5 cannot rotate normally.

[0031] A cleaning rod 9 is provided at the bottom of the connecting shaft 8, and the cleaning rod 9 is in contact with the bottom of the vessel body 1.

[0032] When the device is in use, the cleaning rod 9 will rotate. Since the cleaning rod 9 is in contact with the bottom of the vessel body 1, the cleaning rod 9 will continuously clean the vessel body 1, thereby preventing the material from sticking to the vessel body 1.

[0033] A fixing groove is provided inside the side of the vessel body 1. A piston rod 10 is slidably arranged in the fixing groove, and a return spring 11 is provided inside the fixing groove.

[0034] When the cleaning rod 9 rotates and contacts the piston rod 10, the resistance to the cleaning rod 9 will suddenly increase, and the piston rod 10 will also move inward under the thrust, while the rotational resistance of the cleaning rod 9 will decrease. When the impact occurs, the cleaning rod 9, the stirring shaft 5 and the stirring rod 6 will all vibrate, thereby preventing the material from sticking to the surface of the cleaning rod 9, the stirring shaft 5 and the stirring rod 6, achieving a self-cleaning effect. Afterward, the return spring 11 will push the piston rod 10 back to its original position.

[0035] The vessel body 1 and the vessel cover 2 are fixed together by bolts, and the upper end of the vessel body 1 and the bottom of the vessel cover 2 are arc-shaped.

[0036] When the device is in use, the vessel body 1 and the vessel cover 2 are fixed by bolts. Based on this, the vessel body 1 can be opened or closed by removing the bolts.
