Description

Technical Field

[0001] The utility model relates to the technical field of formaldehyde production, in particular to a distributor for formaldehyde production. Background Art

[0002] Formaldehyde is an important basic chemical raw material. Formaldehyde is mainly produced by oxidizing methanol with air over a silver catalyst or an iron-molybdenum catalyst. In order to control the methanol concentration in the reactor and effectively remove the reaction heat, a large amount of batching steam is used in the oxidation process. Therefore, an air distribution device is required in the formaldehyde production process.

[0003] According to the announcement number CN219615556U, an air distribution device for formaldehyde production is proposed. The air distribution device for formaldehyde production can mix steam, methanol and other gases used for formaldehyde production more evenly by adding swinging blades, a first rotating rod, a second rotating rod, a first bevel gear, a second bevel gear and a third bevel gear and other structures that cooperate with each other, thereby improving the production quality of formaldehyde.

[0004] However, when an emergency situation occurs and all control valves need to be closed, the air distribution device for formaldehyde production needs to close each control valve one by one, which prolongs the valve closing time and is time-consuming and labor-intensive, reducing the safety of formaldehyde production. Therefore, a distributor for formaldehyde production is proposed to solve the above problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a distributor for formaldehyde production, which has the advantage of closing and opening three control valves at the same time, and solves the problem that when an emergency occurs and all the control valves need to be closed, each control valve needs to be closed one by one, which prolongs the valve closing time, is time-consuming and labor-intensive, and reduces the safety of formaldehyde production.

[0006] In summary, the utility model provides the following technical solutions: a formaldehyde production dispenser, comprising a tank body, a dispensing mechanism disposed outside the tank body, and a mixing mechanism disposed above the tank body;

[0007] The distribution mechanism includes three air inlet pipes fixedly mounted on the outside of the tank body, first valves fixedly mounted on the outside of the three air inlet pipes, second valves fixedly mounted on the outside of the three air inlet pipes, and a synchronization mechanism for driving the multiple valves to close and open simultaneously;

[0009] The utility model adopts the technical scheme and is provided with a distribution mechanism, thereby achieving the purpose of closing and opening three control valves at the same time, saving time and labor and improving the safety of formaldehyde production.

[0010] Furthermore, the mixing mechanism includes a casing fixedly mounted on the top of the tank body and a second motor fixedly mounted on the inner top wall of the casing.

[0011] The utility model adopts the above technical scheme and is provided with a mixing mechanism to mix the steam, methanol and other gases for producing formaldehyde. Since the two blades distributed at intervals rotate in opposite directions, the steam, methanol and other gases for producing formaldehyde are mixed more evenly, thereby improving the production quality of formaldehyde.

[0012] Furthermore, the outer surface of the mounting gear is meshed with the outer surface of the synchronous gear ring, and the outer surfaces of the three synchronous gears are meshed with the outer surface of the synchronous gear ring.

[0013] The beneficial effect of adopting the above further solution is that the mounting gear drives the three synchronous gears to rotate through the synchronous gear ring.

[0014] Furthermore, the output shaft of the second motor is fixedly connected to a rotating shaft having one end penetrating through and extending into the tank body through a coupling, and a sleeve is rotatably mounted on the outer surface of the rotating shaft.

[0015] The beneficial effect of adopting the above further solution is that the second motor drives the rotating shaft to rotate.

[0016] Furthermore, a movable hole is opened on the inner top wall of the tank body, and the inner surface of the movable hole is rotatably connected to the outer surface of the sleeve.

[0017] The beneficial effect of adopting the above further solution is that the movable hole makes the sleeve rotation stable.

[0018] Furthermore, transverse bevel gears are fixedly mounted on the outer surface of the rotating shaft and the outer surface of the sleeve, and blades are fixedly mounted on the outer surface of the rotating shaft and the outer surface of the sleeve.

[0019] The beneficial effect of adopting the above further solution is that the rotating shaft and the sleeve drive the two blades to rotate in opposite directions.

[0020] Furthermore, a vertical bevel gear is rotatably mounted on the right side wall of the inner cavity of the housing, and the outer surface of the vertical bevel gear is meshed with the outer surfaces of the two transverse bevel gears.

[0021] The beneficial effect of adopting the above further solution is that the vertical bevel gear causes the two transverse bevel gears to rotate in opposite directions.

[0022] Furthermore, an air outlet pipe having one end penetrating through and extending to the outside of the tank body is fixedly installed inside the tank body, and the air outlet pipe is located at the center of the bottom of the tank body.

[0023] The beneficial effect of adopting the above further solution is that formaldehyde is discharged through the exhaust pipe.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] The distributor for formaldehyde production achieves the purpose of closing and opening three control valves at the same time by providing a distribution mechanism, thereby saving time and labor and improving the safety of formaldehyde production. The distributor is provided with a mixing mechanism to mix the steam, methanol and other gases for producing formaldehyde. Since the two blades distributed at intervals rotate in opposite directions, the steam, methanol and other gases for producing formaldehyde are mixed more evenly, thereby improving the production quality of formaldehyde.
