Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically to an air-blowing mixing device. Background Technology

[0002] In chemical workshops, many chemical reactions need to be carried out in stirred tanks. Stirred tanks are equipped with stirrs that can agitate the reaction liquid inside the stirred tank to accelerate the reaction rate. In order to further increase the reaction rate, some stirrers have vent holes on their impeller blades to allow air to pass through while stirring, further promoting the mixing of the reaction liquid and further increasing the reaction rate.

[0003] The existing technology has the following shortcomings: in some reaction types of reaction products, reactants can easily enter the stirring blade through the vent, which prevents these reactants from participating in the reaction and easily leads to incomplete reaction. In addition, in some designs, although it is possible to prevent reactants from entering the stirring blade, it is still easy to clog the vent, preventing gas from participating in the reaction, resulting in unsatisfactory stirring process and reaction effect. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems and shortcomings by providing an air-blowing stirring device that improves overall work efficiency.

[0005] The technical problem solved by this utility model is:

[0006] (1) Reactants can easily enter the stirring blades through the vent holes, resulting in incomplete reaction;

[0007] (2) Although it can block reactants from entering, it is still easy to clog the vent.

[0008] The objective of this utility model can be achieved through the following technical solution: A blower-type stirring device includes a reaction vessel. A main gas pipe is installed through the middle of the reaction vessel. L-shaped gas guide pipes are connected to the lower two sides of the main gas pipe. A gas guide inner sleeve is fixedly sleeved on the lower outer periphery of the main gas pipe and the upper outer periphery of the two L-shaped gas guide pipes. A transmission gas guide hole is opened at the end of the gas guide inner sleeve. A gas guide outer sleeve is slidably sleeved on the outer periphery of the gas guide inner sleeve. A transmission spring is fixedly connected inside the gas guide outer sleeve near the transmission gas guide hole. The transmission spring is fixedly connected to the end of the gas guide inner sleeve near the transmission gas guide hole. A number of inner gas guide holes are evenly distributed in a ring array on the outer periphery of the gas guide inner sleeve. A number of outer gas guide holes are evenly distributed in a ring array on the outer periphery of the gas guide outer sleeve.

[0009] Preferably, a stirring motor is provided above the reactor, the upper end of the main gas pipe is fixedly installed at the lower end of the drive shaft of the stirring motor, and a rotary joint is rotatably installed on the outer periphery of the upper end of the main gas pipe.

[0010] Preferably, the air inlet of the rotary joint is connected to an air inlet pipe, and an on / off valve is installed on the air inlet pipe.

[0011] Preferably, the inner circumference of the end of the air guide sleeve away from the transmission spring is stepped, and the end of each air guide sleeve away from the transmission spring is respectively sealed and slidably connected to the outer circumference of the corresponding main air pipe and the L-shaped air guide pipe.

[0012] Preferably, the inner and outer air guide holes correspond one-to-one. When the transmission spring has no elasticity, the distance between the stepped end of the outer air guide sleeve and the end of the inner air guide sleeve and the height distance between the outer air guide hole and the inner air guide hole are the same.

[0013] Preferably, a mounting base is installed on the top of the reactor and on the outer periphery of the upper end of the main gas pipe. The mounting base is rotatably connected to the main gas pipe, and a transmission ring is rotatably sleeved on the lower periphery of the mounting base.

[0014] Preferably, a mounting block is sealed and embedded on the top of the reactor and on one side of the mounting base. A transmission shaft is inserted through and rotatably sleeved in the middle of the mounting block. A third gear is installed at the upper end of the transmission shaft, and a fourth gear is installed at the lower end of the transmission shaft. The upper outer circumference of the transmission ring is provided with teeth, and the transmission ring meshes with the fourth gear through the teeth. A first gear is fixedly sleeved on the lower end of the drive shaft of the stirring motor. A support shaft is installed on the lower part of the stirring motor and on one side of the first gear. A second gear is rotatably sleeved on the support shaft. The first gear and the second gear, as well as the second gear and the third gear, maintain meshing and transmission.

[0015] Preferably, a number of diagonal braces arranged in a circular array are fixedly connected to the lower outer periphery of the transmission ring, and an L-shaped scraper is fixedly connected to the lower end of the diagonal braces. The outer periphery of the L-shaped scraper is in contact with and slidably connected to the inner peripheral side wall of the reactor.

[0016] Preferably, a second blade is installed on the side of the outer sleeve of the L-shaped air guide tube near the main air guide tube, and a retaining strip and a retaining groove are provided on the outer periphery of the inner sleeve of the air guide tube to limit sliding in conjunction with the outer sleeve of the air guide tube.

[0017] Preferably, a support ring is rotatably sleeved on the lower outer circumference of the main air tube, and several vertical support rods are installed between the support ring and the transmission ring in a circular array. Several first blades are installed on each vertical support rod in an equidistant and uniformly distributed manner.

[0018] The beneficial effects of this utility model are as follows:

[0019] (1) By balancing the gas pressure and the elastic force, the inner and outer gas guide holes are connected, allowing the gas to stably pass through the inner and outer gas guide holes into the reactor. When the gas passes through, the gas pressure is higher than the outside pressure, preventing the substances in the reactor from entering. When the gas pressure decreases, the balance between the gas pressure and the elastic force of the transmission spring is broken, causing the outer gas guide sleeve to reset. The inner and outer gas guide holes are no longer connected, effectively blocking the reactants and preventing them from entering, thus ensuring the full progress of the reaction.

[0020] (2) The main gas pipe is rotated by the stirring motor, which drives the L-shaped gas pipe, the inner gas pipe sleeve, and the outer gas pipe sleeve to rotate. The rotating L-shaped gas pipe and the outer gas pipe sleeve stir the material in the reactor. While the main gas pipe is rotating, the first gear is rotated, which in turn drives the second gear, the third gear, the transmission shaft, the fourth gear, and the transmission ring to rotate in sequence. Through a series of transmissions, the rotation direction of the transmission ring is opposite to that of the main gas pipe. When the transmission ring drives the vertical support rod and the first blade to rotate, the outer gas pipe sleeve drives the second blade to rotate in the opposite direction to the first blade. This allows the reactants in the reactor to be pushed by the first and second blades to generate a circulating convection, so that the reactants are no longer stirred in layers, but are stirred in a three-dimensional manner across layers, ensuring the efficiency and uniformity of the stirring, and allowing the reactants to react fully.

Detailed Implementation

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0028] Please see Figure 1-4 As shown: A pneumatic stirring device includes a reaction vessel 101. A main air pipe 103 is installed through the middle of the reaction vessel 101. A stirring motor 102 is installed above the reaction vessel 101. The upper end of the main air pipe 103 is fixedly installed at the lower end of the drive shaft of the stirring motor 102. A rotary joint 104 is rotatably installed on the outer periphery of the upper end of the main air pipe 103 and sealed. The air inlet of the rotary joint 104 is connected to an air inlet pipe 105. An on / off valve 106 is installed on the air inlet pipe 105. L-shaped air guide pipes 107 are respectively connected to the lower two sides of the main air pipe 103. The lower periphery of the main air pipe 103 and the two L-shaped air guide pipes 107 are connected to the main air pipe 103. The upper outer periphery of 07 is fixedly sleeved with an inner air guide sleeve 108. The end of the inner air guide sleeve 108 is provided with a transmission air guide hole 110. The outer periphery of the inner air guide sleeve 108 is slidably sleeved with an outer air guide sleeve 109. The inner end of the outer air guide sleeve 109 near the transmission air guide hole 110 is fixedly connected with a transmission spring 113. The transmission spring 113 is fixedly connected to the end of the inner air guide sleeve 108 near the transmission air guide hole 110. The outer periphery of the inner air guide sleeve 108 is provided with a number of inner air guide holes 111 evenly distributed in a ring array. The outer periphery of the outer air guide sleeve 109 is provided with a number of outer air guide holes 112 evenly distributed in a ring array.

[0029] In this embodiment, the rotary joint 104 ensures that the gas supplied by the inlet pipe 105 is stably delivered even when the main gas pipe 103 rotates. The stirring motor 102 rotates the main gas pipe 103, causing the L-shaped gas guide pipe 107, the inner gas guide sleeve 108, and the outer gas guide sleeve 109 to rotate. The rotating L-shaped gas guide pipe 107 and the outer gas guide sleeve 109 stir the material in the reactor 101. Simultaneously, the gas supplied by the main gas pipe 103 increases the pressure inside the inner gas guide sleeve 108 and maintains it at a high pressure level. Subsequently, the gas pressure pushes the outer gas guide sleeve 109 to move and stretch the transmission. Spring 113 generates elastic force, which balances the gas pressure with the elastic force, thereby connecting the inner gas guide hole 111 and the outer gas guide hole 112. This allows gas to stably pass through the inner gas guide hole 111 and the outer gas guide hole 112 into the reactor 101. When the gas passes through, the gas pressure is higher than the outside pressure, preventing substances in the reactor 101 from entering. When the gas pressure decreases, the balance between the gas pressure and the elastic force of the transmission spring 113 is broken, causing the outer gas guide sleeve 109 to reset. The inner gas guide hole 111 and the outer gas guide hole 112 are no longer connected, thus preventing substances in the reactor 101 from entering the inner gas guide hole 111.

[0030] The inner circumference of the end of the air guide sleeve 109 away from the transmission spring 113 is stepped. The end of each air guide sleeve 109 away from the transmission spring 113 is respectively sealed and slidably sleeved with the outer circumference of the corresponding main air pipe 103 and L-shaped air pipe 107. The inner air guide hole 111 and the outer air guide hole 112 correspond one-to-one. When the transmission spring 113 has no elasticity, the distance between the stepped end of the air guide sleeve 109 and the end of the air guide inner sleeve 108 is the same as the height distance between the outer air guide hole 112 and the inner air guide hole 111. The outer circumference of the air guide inner sleeve 108 is provided with a retaining strip and a retaining groove that cooperate with the air guide sleeve 109 to limit sliding.

[0031] In this embodiment, the stepped end of the gas guide sleeve 109 prevents the gas guide sleeve 109 from becoming loose, and the moving distance of the gas guide sleeve 109 and the communication between the outer gas guide hole 112 and the inner gas guide hole 111 are matched, thereby stably preventing the entry of reactants and avoiding blockage.

[0032] A mounting base 201 is sealed and installed on the top of the reactor 101 and on the outer periphery of the upper end of the main gas pipe 103. The mounting base 201 is rotatably connected to the main gas pipe 103. A transmission ring 202 is rotatably sleeved on the lower outer periphery of the mounting base 201. A mounting block 212 is sealed and installed on the top of the reactor 101 and on one side of the mounting base 201. A transmission shaft 213 is inserted through and rotatably sleeved in the middle of the mounting block 212. A third gear 214 is installed on the upper end of the transmission shaft 213, and a fourth gear 215 is installed on the lower end of the transmission shaft 213. The upper outer periphery of the transmission ring 202 has teeth, and the transmission ring 202 meshes with the fourth gear 215 through the teeth. A first gear 209 is fixedly sleeved on the lower end of the drive shaft of the stirring motor 102. A support shaft 210 is installed on the lower part of the stirring motor 102 and on one side of the first gear 209. A second gear 211 is rotatably sleeved on the support shaft 210. The first gear 209 and the second gear 211, as well as the second gear 211 and the third gear 214, are meshed and driven. Several inclined support rods 203 arranged in a ring array are fixedly connected to the lower outer periphery of the transmission ring 202. An L-shaped scraper 204 is fixedly connected to the lower end of the inclined support rod 203. The outer periphery of the L-shaped scraper 204 is attached to and slidably connected to the inner peripheral side wall of the reactor 101. A support ring 207 is rotatably sleeved on the lower outer periphery of the main gas pipe 103. Several vertical support rods 205 arranged in a ring array are installed between the support ring 207 and the transmission ring 202. Several first blades 206 arranged in an equidistant and uniform distribution are installed on each vertical support rod 205. A second blade 208 is installed on the side of the gas guide sleeve 109 located on the L-shaped gas guide pipe 107 near the main gas pipe 103.

[0033] In this embodiment, while the stirring motor 102 rotates the main gas pipe 103, it also rotates the first gear 209, which in turn drives the second gear 211, the third gear 214, the transmission shaft 213, the fourth gear 215, and the transmission ring 202 to rotate in sequence. Through a series of transmissions, the rotation direction of the transmission ring 202 is opposite to that of the main gas pipe 103. When the transmission ring 202 drives the vertical support rod 205 and the first blade 206 to rotate, the gas guide sleeve 109 drives the second blade 208 to rotate in the opposite direction to the first blade 206. This allows the reactants in the reactor 101 to be pushed by the first blade 206 and the second blade 208 to generate a circulating convection. As a result, the reactants are no longer rotated and stirred in layers, but are stirred three-dimensionally across layers, ensuring the efficiency and uniformity of the stirring, and allowing the reactants to react fully.

[0034] In summary, during operation, the balance between gas pressure and elastic force is achieved, thereby connecting the inner gas guide hole 111 and the outer gas guide hole 112. This allows gas to stably pass through the inner gas guide hole 111 and the outer gas guide hole 112 into the reactor 101. When the gas passes through, the gas pressure is higher than the outside pressure, preventing substances in the reactor 101 from entering. When the gas pressure decreases, the balance between the gas pressure and the elastic force of the transmission spring 113 is broken, causing the outer gas guide sleeve 109 to reset. The inner gas guide hole 111 and the outer gas guide hole 112 are no longer connected, effectively blocking reactants and preventing them from entering, thus ensuring the full progress of the reaction.

[0035] During operation, the stirring motor 102 rotates the main gas pipe 103, which in turn drives the L-shaped gas guide pipe 107, the inner gas guide sleeve 108, and the outer gas guide sleeve 109 to rotate. The rotating L-shaped gas guide pipe 107 and the outer gas guide sleeve 109 stir the material inside the reactor 101. Simultaneously with the rotation of the main gas pipe 103, the first gear 209 rotates, which in turn sequentially drives the second gear 211, the third gear 214, the transmission shaft 213, the fourth gear 215, and the transmission ring 202 to rotate. Through this series of transmissions, the material is stirred... The rotation direction of the rotating ring 202 is opposite to that of the main gas pipe 103. When the transmission ring 202 drives the vertical support rod 205 and the first blade 206 to rotate, the gas guide sleeve 109 drives the second blade 208 to rotate in the opposite direction to the first blade 206. This allows the reactants in the reactor 101 to be pushed by the first blade 206 and the second blade 208 to generate a circulating convection. As a result, the reactants are no longer stirred in layers, but are stirred in a three-dimensional manner across layers, which ensures the efficiency and uniformity of the stirring and allows the reactants to react fully.

[0036] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
