Description

Technical Field

[0001] This utility model relates to the field of 2-4(chlorophenyl)-3-methylbutyryl chloride production technology, specifically a circulating cooling structure for the production of 2-4(chlorophenyl)-3-methylbutyryl chloride. Background Technology

[0002] In the industrial production of 2,4-(chlorophenyl)-3-methylbutyryl chloride, the acyl chloride reaction is a typical and violent exothermic process. This reaction is extremely sensitive to temperature. If the heat of reaction cannot be removed in a timely and effective manner, it will lead to uncontrolled temperature in the reaction system. This will not only cause the decomposition of the target product, generate a large number of impurities, and reduce the product yield and purity, but may also lead to serious safety accidents such as material overflow and explosion due to the aggravation of side reactions and high pressure.

[0003] Currently, heat exchangers are commonly used in the industry for water cooling of reaction vessels. However, during long-term operation, the heat exchanger is continuously under high load. The internal coolant gradually increases in temperature due to the continuous absorption of reaction heat, causing the overall heat exchange efficiency to gradually decrease as the operating time increases, which in turn affects the subsequent cooling effect.

The two cooling coils 210 are respectively connected to two heat exchangers 110. The reactor 300 is located inside the cooling sleeve 200 and is driven to rotate by the motor 130. When the cooling liquid circulates inside one of the cooling coils 210, the reactor 300 inside the cooling sleeve 200 is cooled down. At this time, the reactor 300 rotates, which can cool the reactor 300 evenly.

[0032] A first pulley 130a is installed at the output end of the motor 130. A second gear 120b is rotatably connected to the side wall of the side plate 120.

When the reactor 300 rotates, it drives the cross-shaped insert 120a-1 and the first gear 120a-2 to rotate. The first gear 120a-2 drives the third gear 140b to rotate. When the third gear 140b rotates, it drives the second pulley 140a-1 and the first reciprocating threaded rod 140a to rotate via a belt. When the first reciprocating threaded rod 140a rotates, it drives the lifting block 160 to move up and down via a screw mechanism. When the lifting block 160 moves upward, it drives the moving plate 170 to move to the left via the connecting plate 160b. Conversely, when the lifting block 160 moves downward...At this time, the lifting block 160 drives the moving plate 170 to move to the right via the connecting plate 160b.

Not shown in the figure, two one-way racks 170a mesh with two one-way gears 150 respectively. When the moving plate 170 moves to the left, the one-way rack 170a on the left drives the one-way gear 150 on the left to rotate. When the moving plate 170 moves to the right, the one-way rack 170a on the right drives the one-way gear 150 on the right to rotate. When the one-way gear 150 rotates, it drives the first helical gear 150a to rotate. The first helical gear 150a drives the second helical gear 150b-2 and the second reciprocating threaded rod 150b-1 to rotate.

[0034] Two conveying assemblies 400 are symmetrically installed on the top of the base 100. The two conveying assemblies 400 are respectively connected to two cooling coils 210 and two heat exchangers 110. The conveying assemblies 400 are also connected to the reactor 300. When the reactor 300 rotates, it drives the two conveying assemblies 400 to alternately convey the coolant inside the two heat exchangers 110 to the cooling coils 210 for alternating cooling. Each conveying assembly 400 includes a fixed pipe 410 installed on the top of the base 100 and a piston 420 located inside the fixed pipe 410. An inlet pipe 410a is installed on the side wall of the fixed pipe 410, and the other end of the inlet pipe 410a is connected to the heat exchanger 110. A first one-way valve 410a-1 is installed on the body of the inlet pipe 410a. An outlet pipe 410b is installed on the top of the fixed pipe 410, and the other end of the outlet pipe 410b is connected to the cooling coil 210. A second one-way valve 410b-1 is installed on the body of the outlet pipe 410b. A fixing rod 420a is installed on the side wall of the piston 420. A second reciprocating threaded hole 420a-1 is opened at the side end of the fixing rod 420a. The second reciprocating threaded rod 150b-1 rotates and extends into the second reciprocating threaded hole 420a-1. When the one-way gear 150 rotates, the piston 420 is pushed to reciprocate inside the fixed tube 410 by the screw structure. When the piston 420 moves outward inside the fixed tube 410, the first one-way valve 410a-1 opens and the second one-way valve 410b-1 closes. The coolant inside the heat exchanger 110 enters the fixed tube 410 through the inlet pipe 410a. When the piston 420 moves inward inside the fixed tube 410, the first one-way valve 410a-1 closes and the second one-way valve 410b-1 opens. The coolant inside the fixed tube 410 is transported to the cooling coil 210 through the outlet pipe 410b and then transported back to the heat exchanger 110 through the cooling coil 210.

[0035] Combination Figures 1-5 This embodiment describes a circulating cooling structure for the production of 2-4-(chlorophenyl)-3-methylbutyryl chloride. During use, the reaction liquid is poured into the reactor 300. The motor 130 is then started to rotate the reactor 300. This rotation of the reactor 300 causes the cross-shaped insert 120a-1 and the first gear 120a-2 to rotate, which in turn rotates the first reciprocating threaded rod 140a, pushing the lifting block 160 up and down. As the lifting block 160 moves, it drives two conveying components 400 to start alternately, alternately conveying the coolant inside one side of the heat exchanger 110 to the corresponding cooling coil 210 for water cooling. This prevents the internal coolant of a single heat exchanger 110 from overheating due to prolonged operation, thus affecting subsequent cooling efficiency.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
