DETAILED DESCRIPTION

[0030] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figure 1-7 The present invention shows a production reaction equipment for preparing o-phthalaldehyde disinfectant, comprising a barrel 1, a feeding hopper 2 extending into the barrel 1 is fixedly connected to the top of the barrel 1, an atomizing mixing barrel 3 installed in the barrel 1 is sleeved at the lower end of the feeding hopper 2, an injection barrel 4 is arranged in the middle of the atomizing mixing barrel 3, a compression mixing chamber 401 is opened in the injection barrel 4, a diffusion cover 5 fixed on the outer wall of the injection barrel 4 is connected to the outside of the compression mixing chamber 401, a feeding channel 402 is connected to the upper end of the compression mixing chamber 401, and a feeding channel 402 is connected to the upper end of the compression mixing chamber 401. The upper end of the material channel 402 is connected with a receiving cover 6 fixed on the upper end of the injection tube 4. The upper end of the receiving cover 6 is sleeved on the lower end opening of the feeding hopper 2 and is rotatably connected to the outer wall of the lower end opening of the feeding hopper 2. The receiving cover 6 is penetrated by an upper rotating shaft 7 which is fixedly connected to the injection tube 4 and extends to the top of the feeding hopper 2. The upper rotating shaft 7 is provided with an air intake channel 701 which penetrates itself and is connected with the compression mixing chamber 401. The upper end of the upper rotating shaft 7 is connected with an air intake pipe 8 through a rotating joint. The air intake pipe 8 is connected with an external high-pressure air pump.

[0033] The outer wall of the injection cylinder 4 is fixedly connected with an injection pipe 11 which is evenly distributed in an arc shape and has a nozzle facing the inner wall of the atomizing mixing cylinder 3. A water injection chamber 403 connected to the injection pipe 11 is provided in the injection cylinder 4. A lower rotating shaft 12 fixedly connected to the injection cylinder 4 is connected below the water injection chamber 4. The lower rotating shaft 12 is provided with a water inlet channel 1201 which passes through itself and is connected to the water injection chamber 403. The lower end of the lower rotating shaft 12 is connected to a water inlet pipe 13 through a rotating joint. The water inlet pipe 13 is connected to a submersible pump 14 installed on the bottom plate of the cylinder body 1.

[0034] Specifically, when preparing the o-phthalaldehyde disinfectant, the following steps are included:

[0035] Step 1: inject pure water into the cavity of the cylinder 1 below the atomizing mixing cylinder 3, pour solid phthalaldehyde powder into the feeding hopper 2, and the solid powder flows into the receiving cover 6 under the action of gravity;

[0036] Step 2, start the driving mechanism of the upper rotating shaft 7, the external high-pressure air pump and the submersible pump 14, the upper rotating shaft 7 drives the injection tube 4 to rotate, and the injection tube 4 drives the diffusion cover 5 and the injection pipe 11 thereon to make circular motion. At the same time, the high-pressure air pump injects the high-pressure gas into the compression mixing chamber 401 through the intake pipe 8 and the intake channel 701 of the upper rotating shaft 7. The high-pressure airflow is injected into the diffusion cover 5 after passing through the compression mixing chamber 401 and then ejected. As the airflow passes through the compression mixing chamber 401 at a high speed, the negative pressure generated sucks the o-phthalaldehyde powder in the receiving cover 6, so that the high-pressure airflow and the o-phthalaldehyde powder are mixed in the compression mixing chamber 401, and then enter the diffusion cover 5 with a gradually expanding inner diameter, generating a powder spray that is sprayed toward the atomization On the inner wall of the mixing cylinder 3, at the same time, the submersible pump 14 injects the pure water at the bottom of the cylinder 1 into the water injection chamber 403 through the water inlet pipe 13 and the water inlet channel 1201 of the lower rotating shaft 12, and then sprays it out from the multiple injection pipes 11 distributed equidistantly in an arc shape. The water column sprayed from the injection pipe 11 collides with the inner wall of the atomizing mixing cylinder 3, causing the water flow to sputter and produce a large amount of atomized water droplets. In addition, the water flow infiltrates the inner wall of the atomizing mixing cylinder 3 and slides down with its inner wall. The atomized powder is fully contacted and dissolved with the atomized water droplets and the wet inner wall of the atomizing mixing cylinder 3, so that the atomized powder is quickly dissolved, mixed and settled, and the generated mixed liquid flows into the cavity at the lower part of the cylinder 1 through the lower end opening of the atomizing mixing cylinder 3.

[0037] Compared with the traditional preparation method of o-phthalaldehyde disinfectant by feeding and stirring, the present invention uses a spray barrel 4 with a compression mixing chamber 401 opened inside and a diffusion cover 5 installed outside. When the disinfectant is prepared, a high-pressure airflow is used to compress, mix and diffuse the o-phthalaldehyde powder to generate atomized raw material powder and spray the atomized powder onto the inner wall of the atomizing mixing barrel 3. At the same time, pure water is extracted by a submersible pump 14 and sprayed onto the inner wall of the atomizing mixing barrel 3 through a spray pipe 11 on the spray barrel 4, so that the inner wall of the atomizing mixing barrel 3 is wetted to form a flowing water film and atomized water droplets are generated by the impact and rebound of the water column. As the spray barrel 4 rotates, the atomized powder is fully contacted and dissolved with the atomized water droplets and the flowing water film on the inner wall of the atomizing mixing barrel 3, thereby improving the uniformity of the contact between the o-phthalaldehyde raw material and the pure water, reducing the situation where the raw material powder is concentratedly poured and contacts with the pure water to generate powder clumps, improving the mixing uniformity, and reducing the time for dissolving and stirring.

[0038] See also Figure 5 The atomizing mixing cylinder 3 is a vertical cylindrical structure with openings at both ends and a spindle-shaped cross section, and its upper and lower parts are a pair of integrally formed and back-to-back conical cylinders.

[0039] Specifically, the atomizing mixing cylinder 3, which is spindle-shaped and has conical cylinders at the upper and lower parts, has two large conical surfaces, so that pure water has a larger wetting area on the inner wall of the atomizing mixing cylinder 3, thereby increasing the contact area between the atomized powder and the wetted inner wall, and improving the dissolution uniformity and dissolution efficiency.

[0040] See also Figure 7 The receiving cover 6 includes a cylindrical portion 601, a conical portion 602 and a circular tube portion 603 integrally formed from top to bottom. The cylindrical portion 601 is rotatably sleeved on the outer side of the lower opening of the feeding hopper 2, the upper rotating shaft 7 passes through the conical portion 602, and the circular tube portion 603 is fixed on the injection tube 4 and connected to the feed channel 402.

[0041] Specifically, when the injection tube 4 rotates, it does not affect the raw material powder from being injected into the compression mixing chamber 401 from the receiving cover 6 .

[0042] See also Figure 6 The injection tube 4 is a vertical cylindrical structure, and a plurality of injection pipes 11 and diffusion covers 5 are equidistantly distributed on the side wall of the injection tube 4 in a circumferential manner.

[0043] Specifically, after the o-phthalaldehyde powder contacts the water flowing on the inner wall of the atomizing mixing tube 3, the water jetted by the adjacent circular spray tube 11 quickly flushes the mixed liquid on the inner wall, making it easier for the new powder to mix with the pure water on the inner wall, and rarely causing the evenly distributed mixed liquid to have too high a concentration.

[0044] See also Figure 2The upper rotating shaft 7 is connected to the output shaft of the driving motor 10 through the transmission gear set 9, the lower rotating shaft 12 is fixedly connected to the stirring blade 24, the upper part of the cylinder 1 is provided with a water injection pipe 15 connected to the cavity below the atomizing mixing cylinder 3, and the lower part of the cylinder 1 is connected with a discharge pipe 16.

[0045] Specifically, the mixed liquid in which o-phthalaldehyde is dissolved is fully diffused in the pure water, thereby further improving the mixing uniformity.

[0046] Second implementation method:

[0047] Figure 8-13 A production reaction equipment for preparing o-phthalaldehyde disinfectant is shown. On the basis of the first embodiment, a grinding chamber 201 is provided at the lower part of the feeding hopper 2, a grinding hammer 17 is nested in the grinding chamber 201, a columnar portion 1701 is provided at the upper part of the grinding hammer 17, a first prism tube 18 penetrating the grinding hammer 17 is nested in the columnar portion 1701, and the first prism tube 18 is fixedly connected to the upper rotating shaft 7; a guide ring 19 rotatably connected to the upper part of the columnar portion 1701 is sleeved, and the guide ring 19 is fixedly connected to the inner wall of the grinding chamber 201 through a fixing plate 20; a sliding column 1702 is fixedly connected to the circumferential side wall of the columnar portion 1701, and a guide groove 1901 for the sliding column 1702 to slide up and down is provided on the inner wall of the guide ring 19.

[0048] Specifically, the upper rotating shaft 7 drives the grinding hammer 17 to rotate through the first prism tube 18, and the grinding hammer 17 cooperates with the inner wall of the grinding chamber 201 to grind and crush the o-phthalaldehyde powder, and break the agglomerates therein, so that the particle size of the o-phthalaldehyde powder is smaller, which is convenient for subsequent high-pressure jet injection and improves the dissolution effect; in addition, when the grinding hammer 17 rotates, the sliding column 1702 on the columnar portion 1701 slides up and down in the guide groove 1901 of the guide ring 19, thereby driving the grinding hammer 17 to move up and down, realizing the up and down rotation grinding of the grinding hammer 17, improving the grinding effect, and at the same time, intermittently changing the feeding speed of the o-phthalaldehyde powder, reducing the accumulation of powder, and facilitating the compression mixing chamber 401 to negatively pressure suction the powder.

[0049] See also Fig.10 The guide groove 1901 is a closed annular groove arranged at an angle, the columnar portion 1701 abuts and slides against the inner wall of the guide ring 19 , and the vertical length of the columnar portion 1701 is greater than twice the length of the guide ring 19 .

[0050] Specifically, the grinding hammer 17 can rotate up and down smoothly. At the same time, the columnar portion 1701 is used to block the inner side of the guide groove 1901 to prevent powder from entering the guide groove 1901.

[0051] See also Fig.11 and Fig.12A splash wheel suspended on the pure water surface is slidably sleeved under the lower rotating shaft 12, and a second prism tube 23 is fixedly connected to the lower rotating shaft 12. The splash wheel includes a sliding ring 21 sleeved on the outside of the second prism tube 23 and a water-slapping rod 22 fixedly connected to the sliding ring 21. The longitudinal cross-section of the water-slapping rod 22 is triangular in the upper part and semicircular in the lower part.

[0052] For details, please refer to Fig.13 The lower rotating shaft 12 drives the splash wheel suspended on the pure water surface to rotate through the second prism tube 23. The splash wheel is affected by the centrifugal force and the lifting effect of the liquid surface, slides upward along the second prism tube 23 to leave the water surface, and then falls on the liquid surface again under the action of gravity. The above-mentioned up and down movement process is repeated, and the water-slapping rod 22 hits the liquid surface to generate water splashes. Then, as the contact area between the water-slapping rod 22 and the pure water near the liquid surface gradually increases, the splashing water absorbs and dissolves the atomized powder entering the cavity above the liquid surface for a second time, further improving the dissolution effect.

[0053] See also Fig.12 The sliding ring 21 and the water-beating rod 22 are both made of hollow light materials. A prismatic hole that cooperates with the second prismatic tube 23 is opened at the center of the sliding ring 21.

[0054] Specifically, it is convenient for the water-slapping rod 22 to perform circular motion and up and down slapping motion on the water surface.

[0055] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
