Description

Technical Field

[0001] This utility model belongs to the field of chemical engineering technology, and more specifically, it relates to a water-gas mixing device for a reaction vessel. Background Technology

[0002] The production of papermaking additives generally involves combining and mixing various raw materials, followed by a chemical reaction to form the additives. During the mixed production of papermaking additives, a reaction vessel water-air mixing device is required. Various raw materials are placed inside the device, and the stirring components inside the device stir and mix the various raw materials, which facilitates the production of papermaking additives.

[0003] According to CN202121727240.3, this utility model discloses a synthesis apparatus for manufacturing water-soluble polyester resin, including a reactor. The reactor has four legs connected to its bottom, feed pipes fixedly connected to the left and right sides of the top of the reactor, a discharge pipe fixedly connected to the bottom of the reactor, and a slag discharge pipe fixedly connected to the left side of the reactor. A motor is installed at the top of the reactor, between the two feed pipes. This utility model relates to the technical field of resin production equipment. This synthesis apparatus for manufacturing water-soluble polyester resin, by incorporating an aeration mechanism, introduces nitrogen into the reactor for initial air replacement. Simultaneously, during the stirring process, it facilitates uniform mixing of raw materials, improving mixing efficiency. Furthermore, impurities generated during the mixing process can rise to the top of the mixture with the aeration and be discharged through the slag discharge pipe, thus improving functionality compared to traditional air inlet pipes.

[0004] Based on the above, in existing reactor water-gas mixing devices, water and gas are usually mixed by stirring the agitator blades. Since the gas will rise, it is easy for the gas to not come into contact with the water, which affects the mixing efficiency of water and gas. Utility Model Content

The water-air mixing mechanism is located inside the mixing body.

[0008] Furthermore, the protective positioning mechanism includes: a parallel groove and a protective torsion spring; the parallel groove is located at the middle of the upper end face of the observation frame, and the protective cover rotates inside the parallel groove; the protective torsion spring is fixedly connected to the rear side inside the observation frame, and the protective torsion spring and the protective rotating shaft are elastically connected.

[0009] Furthermore, the protective positioning mechanism also includes: a protective insertion hole, a protective pin, and a protective lever; the protective insertion hole is located in the middle of the left end face of the protective cover; the protective pin is slidably connected to the left side inside the observation frame, and the protective insertion hole and the protective pin are connected by insertion; the protective lever is fixedly connected to the left end face of the protective pin, and the protective lever slides on the left side of the observation frame.

[0010] Furthermore, the protective positioning mechanism also includes: a protective connecting block and a protective spring; the protective connecting block is fixedly connected to the lower side of the protective pin, and the protective connecting block is slidably connected to the left side inside the observation frame; the protective spring is fixedly connected to the left side inside the observation frame, and the protective connecting block and the protective spring are elastically connected.

[0011] Furthermore, the protective blocking mechanism includes a protective gear and a connecting gear; the protective gear is coaxially fixedly connected to the front side of the protective rotating shaft, and the protective gear rotates inside the right side of the observation frame; the connecting gear is rotatably connected inside the right side of the observation frame, and the protective gear and the connecting gear mesh together to form a gear transmission mechanism.

[0012] Furthermore, the protective blocking mechanism also includes: a blocking gear and a blocking rack; the blocking gear is rotatably connected to the right side inside the observation frame, and the blocking gear and the connecting gear mesh together to form a gear transmission mechanism; the blocking rack is fixedly connected to the upper end face of the blocking slider, and the blocking gear and the blocking rack mesh together to form a gear and rack transmission mechanism.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model employs a protective positioning mechanism to ensure that the protective cover protects the mixing device inside the parallel groove, preventing damage caused by direct impact from the outside. The protective hole and protective pin fix the position of the protective cover, and the protective cover protects the mixing device, ensuring the sealing of the mixing device.

[0016] This invention employs a protective blocking mechanism. When the protective cover is opened, the blocking slider slides to block the observation frame, allowing the worker to observe the interior of the mixing device. This prevents unpleasant odors from directly impacting the worker and causing discomfort, thus ensuring the worker's health. When the protective cover is closed, the blocking slider slides back into the mixing cover, allowing the worker to easily add or remove items through the observation frame, making the mixing device convenient to use.

[0017] This invention employs a water-air mixing mechanism to achieve a vacuum state inside the mixing body. When the mixing motor drives the mixing stirring blades to stir the water and air, it also drives the mixing auger to rotate. The rotation of the mixing auger moves the rising gas to the position of the water for mixing. At the same time, it avoids the rising gas from affecting the mixing efficiency of the gas and water, thus ensuring the efficiency of the gas and water mixing. Attached Figure Description

[0034] The protective positioning mechanism also includes a protective connecting block 802 and a protective spring 803. The protective connecting block 802 is fixedly connected to the lower side of the protective pin 8 and slidably connected to the left side inside the observation frame 5.

The blocking gear 10 and the blocking rack 1101 mesh together to form a gear and rack transmission mechanism. During use, the connecting gear 9 rotates, causing the meshing blocking gear 10 to rotate. The rotation of the blocking gear 10 causes the meshing blocking rack 1101 to slide. The sliding of the blocking rack 1101 causes the blocking slider 11 to slide.

[0037] The specific usage and function of this first embodiment are as follows:

[0038] During use, the protective cover 7 rotates, causing the protective shaft 6 to rotate. The protective cover 7 rotates inside the parallel groove 501. The rotation of the protective shaft 6 causes the protective torsion spring 601 to extend and retract. The elastic force of the protective torsion spring 601 causes the protective cover 7 to rotate and open. The rotation of the protective cover 7 causes the protective insertion hole 701 to rotate. The protective insertion hole 701 rotates to the position of the protective pin 8. The operator moves the protective lever 801 to slide. The sliding of the protective lever 801 causes the protective pin 8 to slide. Whether the protective pin 8 is inserted into the protective insertion hole 701 is determined. The sliding of the protective pin 8 causes the protective connecting block 802 to slide. The sliding of the protective connecting block 802 causes the protective spring 803 to extend and retract. The 803 spring force drives the protective pin 8 to insert into the protective socket 701, fixing the protective cover 7 closed. This allows the protective cover 7 to protect and open the mixing device. The rotation of the protective cover 7 drives the protective shaft 6 to rotate, which in turn drives the protective gear 602 to rotate. The rotation of the protective gear 602 drives the meshing connecting gear 9 to rotate, which in turn drives the meshing blocking gear 10 to rotate. The rotation of the blocking gear 10 drives the meshing blocking rack 1101 to slide, which in turn drives the blocking slider 11 to slide. This ensures that when the protective cover 7 is open, the blocking slider 11 provides protection, preventing the chemical odor inside the device from impacting the personnel.
