[0002] Methacrylic acid is an organic compound with the chemical formula C4H6O2. It is a colorless crystalline powder or a colorless transparent liquid, soluble in water and most organic solvents such as ethanol and ether.

A current patent describes a dehydration device (patent publication number CN203719328U), comprising a volume chamber, a deformable sealed container, a water and air extraction pipe, and a dual-purpose wet and dry air pump. The deformable sealed container is placed inside the volume chamber, and its upper end is equipped with a sealing cap. The water and air extraction pipe is located inside the deformable sealed container, passing through the sealing cap or the side wall of the deformable sealed container and connecting to the dual-purpose wet and dry air pump. A one-way valve is installed inside the water and air extraction pipe. This invention has a simple structure, low energy consumption, convenient operation, facilitates liquid removal, low noise during operation, and minimal damage to the dehydrated product, exhibiting excellent practicality and broad application value.

[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] Please see Figures 1-6 This utility model provides a technical solution: a reaction dehydration device applied in the preparation process of methacrylic acid, including a sleeve mechanism 2, the sleeve mechanism 2 having a one-way opening structure at the top, a guide ring assembly 201 fixedly connected to the outside of the sleeve mechanism 2, the main body of the guide ring assembly 201 having a ring structure, the diameter of the guide ring assembly 201 being larger than the diameter of the sleeve mechanism 2, a cylindrical support rod assembly 203 fixedly connected to the top surface of the sleeve mechanism 2, the support rod assembly 203 being fixedly connected to the top surface of the sleeve mechanism 2 in a ring array, a sleeve assembly 204 fixedly connected to the top surface of the support rod assembly 203, the sleeve assembly 204 having a ring structure, and a guide tooth assembly 205 fixedly connected to the outer circumferential surface of the sleeve assembly 204 in a ring array;

[0025] By providing a guide gear assembly 205 that is fixedly connected to the outside of the sleeve assembly 204, it can mesh with the drive gear 104 for transmission during use.

[0026] See Figure 1 , Figure 6 The sleeve mechanism 2 is rotatably connected to the top surface of the support mechanism 1, and the base assembly 101 with a hollow structure is fixedly connected to the bottom surface of the support mechanism 1.

[0027] By fixing a base assembly 101 to the bottom surface of the support mechanism 1, it can support and bear the load for the servo motor 102 when in use.

[0028] See Figure 3 , Figure 5 The seat assembly 101 is used to support the support mechanism 1, and a servo motor 102 is installed on the bottom surface of the support mechanism 1.

[0029] By installing a servo motor 102 on the bottom surface of the support mechanism 1, it can drive the drive gear 104 to rotate during use.

[0030] See Figure 2 , Figure 4 The servo motor 102 has an output shaft at its top, and a drive shaft 103 is mounted on the output shaft.

[0031] Stable power output can be achieved by mounting a drive shaft 103 on the top output shaft of the servo motor 102.

[0032] See Figure 4 , Figure 6 The drive shaft 103 is rotatably connected to the inner side of the support mechanism 1 via a bearing seat, and a drive gear 104 is fixedly connected to the top surface of the drive shaft 103.

[0033] By fixing a drive gear 104 to the top of the drive shaft 103, stable power transmission can be achieved during use.

[0034] See Figure 1 , Figure 2 The drive gear 104 meshes with the guide gear assembly 205 for transmission, and the servo motor 102 and the drive gear 104 are used to drive the guide gear assembly 205 to rotate.

[0035] Efficient power transmission can be achieved by setting up a drive gear 104 and a guide gear assembly 205 that mesh with each other.

[0036] See Figure 3 , Figure 4 A fixing bolt 202 is screwed onto the outside of the sleeve mechanism 2, and a conduit assembly 3 is installed through the fixing bolt 202. A filter plate assembly 301 is embedded inside the conduit assembly 3, and a drain hole 302 is opened on the outside of the conduit assembly 3.

[0038] During operation, in the preparation of methacrylic acid, the reactants are placed inside the conduit assembly 3 and placed on the filter plate assembly 301. Then, the conduit assembly 3 is inserted into the groove at the top of the sleeve mechanism 2, and the fixing bolt 202 is screwed into the sleeve mechanism 2 to tighten and limit the conduit assembly 3 in the sleeve mechanism 2.

[0039] After the tightening limit is completed, the servo motor 102 installed on the bottom surface of the support mechanism 1 is started to drive the transmission shaft 103 and the drive gear 104 to rotate. The drive gear 104 and the guide gear assembly 205 set on the outside of the sleeve assembly 204 are meshed to achieve efficient dehydration of the current reactant. The dehydrated liquid is collected through the sleeve mechanism 2 and then pumped out by a subsequent water pump to complete the removal.

[0040] In summary, the device can achieve stable power output by having a guide tooth assembly 205 fixedly connected to the outer surface of the sleeve assembly 204.
