Abstract
Description
Technical Field
[0001] This application relates to the field of chemical production equipment, and in particular to an internal screw conveyor mixer for polyacrylamide. Background Technology
[0002] Polyacrylamide is a high molecular weight compound with a wide range of applications, including as a flocculant, thickener, reinforcing agent, and surfactant. In the chemical production field, polyacrylamide is granulated through a series of processes such as grinding and drying, and requires a mixing process to form the finished polyacrylamide granules.
[0003] Existing polyacrylamide mixers include a vessel body, an auger, and a feed pipe. The auger is vertically installed inside the vessel body, and one end of the feed pipe is connected to the vessel body. Users pour materials into the vessel body through the feed pipe. The auger includes an outer cylinder and a spiral auger. The outer cylinder is vertically installed inside the vessel body, and the spiral auger is coaxially connected inside the outer cylinder. When the spiral auger rotates, it can drive the material to be vertically lifted. During the process of lifting the material by the spiral auger, the material is mixed evenly, thereby making the particle size of the material output by the auger uniform.
[0004] The aforementioned technical solutions have the following drawbacks: the material has a high moisture content before being poured into the reactor, and additional equipment is required to dry the material, resulting in low production efficiency. Utility Model Content
[0005] To improve the efficiency of material drying, this application provides an internal screw conveyor mixer for polyacrylamide.
[0006] The polyacrylamide internal screw mixer provided in this application adopts the following technical solution:
[0007] A polyacrylamide internal auger mixer includes a storage tank, an auger lifting mechanism, a feed pipe, and a drive mechanism. The auger lifting mechanism is vertically installed inside the storage tank, and one end of the feed pipe is connected to the storage tank. The drive mechanism is installed outside the storage tank and is used to drive the auger lifting mechanism. The storage tank is provided with a top cover, and multiple fans are installed on the top cover. The fans pass through and are fixed to the top cover.
[0008] By adopting the above technical solution, and by setting up an lifting auger mechanism inside the storage tank, the user can inject materials into the storage tank through the feed pipe. The lifting auger mechanism inside the storage tank lifts the materials from the bottom of the storage tank to the top and delivers them out. When the lifting auger mechanism lifts the materials, the materials are mixed evenly inside the lifting auger mechanism, thereby making the particle size of the materials delivered from the top of the lifting auger uniform. When the materials are in the storage tank, the fan can work and play a ventilation role, thereby reducing the temperature of the materials. When the materials contain water vapor, the water vapor in the materials is easy to dissipate and accumulate in the storage tank. The fan can accelerate the discharge of water vapor in the storage tank, making the materials drier. During the mixing process, the temperature and moisture content of the materials decrease, which can improve production efficiency.
[0009] Optionally, a valve body is provided on the feed pipe, which is used to control the opening and closing of the feed pipe.
[0010] By adopting the above technical solution, by setting a valve body on the feed pipe, the valve body can control the opening and closing of the feed pipe. When the material enters the storage tank and is mixed and lifted, the probability of foreign matter entering the storage tank through the feed pipe is reduced.
[0011] Optionally, the storage vessel is provided with a discharge pipe, which is inclined and connected to the bottom of the storage vessel at the top. A valve body is provided on the discharge pipe to control the opening and closing of the discharge pipe.
[0012] By adopting the above technical solution, and by setting a discharge pipe on the storage tank and setting the discharge pipe at an angle, the material at the bottom of the storage tank can be discharged through the discharge pipe, which makes it convenient for users to quickly discharge the material in the storage tank.
[0013] Optionally, the lifting auger mechanism includes an outer cylinder and a spiral auger. The outer cylinder is a cylindrical structure and is vertically fixed inside the storage tank. The lower end of the outer cylinder is connected to the bottom of the storage tank, and the upper end of the outer cylinder passes through the top cover. The spiral auger is coaxially rotatably connected inside the outer cylinder. A feed inlet is provided on the lower side of the outer cylinder, and a discharge outlet is provided on the side wall outside the top cover at the upper end of the outer cylinder.
[0014] By adopting the above technical solution, the outer cylinder is set vertically, and a feed inlet and a discharge outlet are opened on the side wall of the outer cylinder. The material in the storage tank can enter the outer cylinder through the feed inlet. When the spiral auger rotates, the material can be vertically lifted between the spiral auger and the outer cylinder. Due to the joint compression and friction of the material by the outer cylinder and the spiral auger, the material can generate heat, thereby causing water vapor to evaporate and achieving the effect of drying the material.
[0015] Optionally, a sieve plate is provided in the outer cylinder, which is used to cover the feed inlet.
[0016] By adopting the above technical solution, by setting a sieve plate on the outer cylinder, materials with smaller particle sizes can enter the outer cylinder and be lifted. When a lot of materials with larger particle sizes accumulate at the bottom of the storage tank, the user can discharge the materials with larger particle sizes through the discharge pipe, so that the materials with larger particle sizes can be re-ground.
[0017] Optionally, the spiral auger includes a shaft and blades. The shaft is vertically arranged inside the outer cylinder, and the lower end of the shaft passes through the bottom of the storage tank. The blades are connected to the shaft. The drive mechanism includes a motor, two pulleys and a belt. One pulley is mounted on the output shaft of the motor, and the other pulley is fixed to the lower end of the shaft. The belt is sleeved on the two pulleys.
[0018] By adopting the above technical solution, by making the rotating shaft pass through the bottom of the storage tank, the drive mechanism can be connected to the rotating shaft and drive the spiral auger to rotate. By setting a pulley on the motor, the pulley drives the belt to rotate, thereby making the motor and rotating shaft connected in transmission.
[0019] Optionally, the fan is installed at the upper end of the outer cylinder.
[0020] By adopting the above technical solution, by installing a fan at the upper end of the outer cylinder, the fan can increase the ventilation speed inside the outer cylinder. When the lifting auger mechanism lifts the material, the material temperature rises and water vapor is released. The fan can then discharge the water vapor inside the outer cylinder, keeping the material dry.
[0021] Optionally, a connector is provided inside the outer cylinder, which is located on the lower side of the fan at the upper end of the outer cylinder, and a ventilation hole is provided on the connector.
[0022] By adopting the above technical solution, by setting a connector inside the outer cylinder, the connector is fixed in the outer cylinder, and the spiral auger can be rotatably connected to the connector, so that the spiral auger is stably connected to the outer cylinder. By setting the fan above the connector and opening ventilation holes on the connector, the fan can blow air onto the material lifted in the spiral auger, so that the water vapor emitted by the material can be discharged.
[0023] In summary, the beneficial technical effects of this application are as follows:
[0024] 1. By installing a lifting auger mechanism inside the storage tank, the user can inject materials into the storage tank through the feed pipe. The lifting auger mechanism inside the storage tank lifts the materials from the bottom of the storage tank to the top of the storage tank and sends them out. When the lifting auger mechanism lifts the materials, the materials are mixed evenly inside the lifting auger mechanism, so that the particle size of the materials sent out from the top of the lifting auger is uniform. When the materials are in the storage tank, the fan can work and play a ventilation role, thereby reducing the temperature of the materials. When the materials contain water vapor, the water vapor in the materials is easy to dissipate and accumulate in the storage tank. The fan can accelerate the discharge of water vapor in the storage tank, making the materials drier. During the mixing process, the temperature and moisture content of the materials decrease, which can improve production efficiency.
[0025] 2. By setting the outer cylinder vertically and opening the inlet and outlet on the side wall of the outer cylinder, the material in the storage tank can enter the outer cylinder through the inlet. When the spiral auger rotates, the material can be vertically lifted between the spiral auger and the outer cylinder. Due to the joint compression and friction of the material by the outer cylinder and the spiral auger, the material can generate heat, thereby causing water vapor to evaporate and achieving the effect of drying the material.
[0026] 3. By setting a connector inside the outer cylinder, the connector is fixed inside the outer cylinder, and the spiral auger can be rotatably connected to the connector, so that the spiral auger is stably connected inside the outer cylinder. By setting the fan above the connector and opening ventilation holes on the connector, the fan can blow air onto the material lifted in the spiral auger, so that the water vapor emitted by the material can be discharged.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.
[0032] This application discloses an internal screw conveyor mixer for polyacrylamide, referring to...Figure 1 and Figure 2 The system includes a storage tank 1, a lifting auger mechanism 2, a feed pipe 3, a discharge pipe 4, and a drive mechanism 5. The lifting auger mechanism 2 is located inside the storage tank 1 and is used to vertically lift the material inside the storage tank 1. The drive mechanism 5 is located below the storage tank 1 and is connected to the lifting auger mechanism 2. The feed pipe 3 and the discharge pipe 4 are connected to the storage tank 1. Users pour material into the storage tank 1 through the feed pipe 3, and the material in the storage tank 1 can be discharged through the discharge pipe 4. During use, the lifting auger mechanism 2 vertically conveys the material from the storage tank 1 out of the storage tank 1. While conveying the material, the material is uniformly mixed, achieving the purpose of mixing.
[0033] Reference Figure 1 and Figure 2 The storage vessel 1 has an opening that faces vertically upwards. A top cover 11 is installed on the storage vessel 1, covering it. Multiple fans 6 are installed on the top cover 11, passing through and connecting to it. The fans 6 are used for ventilation. When material enters the storage vessel 1, it may be in a high-temperature or humid state. The fans 6 can cool the material in the storage vessel 1 or remove water vapor, thereby reducing the chance of material deterioration.
[0034] Reference Figure 2 The lifting auger mechanism 2 includes an outer cylinder 21 and a spiral auger 22. The outer cylinder 21 is a cylindrical structure and is vertically installed inside the storage vessel 1. The spiral auger 22 is coaxially connected to the outer cylinder 21. The lower end of the outer cylinder 21 is fixed to the bottom surface of the storage vessel 1, and the upper end of the outer cylinder 21 passes through the top cover 11 and extends outside the storage vessel 1. A feed inlet 211 is provided on the lower side wall of the outer cylinder 21, and a discharge outlet 212 is provided at the upper end of the outer cylinder 21, located on the top cover 11. The material in the storage vessel 1 can enter the outer cylinder 21 through the feed inlet 211. During the rotation of the spiral auger 22, the material is lifted inside the outer cylinder 21 and discharged through the discharge outlet 212.
[0035] Reference Figure 2 The outer cylinder 21 is equipped with a sieve plate 213, which is located at the feed inlet 211. The sieve plate 213 has multiple sieve holes. When the material enters the storage tank 1, the material with a smaller particle size can pass through the sieve plate 213 and enter the outer cylinder 21, while the material with a larger particle size is on the outside of the outer cylinder 21, thus achieving the effect of screening the material.
[0036] Reference Figure 1The feed pipe 3 is inclined, and its lower end is connected to the storage vessel 1. The feed pipe 3 is also connected to the bottom end of the storage vessel 1. The user injects material into the storage vessel 1 through the feed pipe 3. A valve body 31 is installed on the feed pipe 3. The valve body 31 is used to control the opening and closing of the feed pipe 3. After the material is injected into the feed pipe 3, closing the valve body 31 can reduce the probability of water vapor in the storage vessel 1 flowing along the feed pipe 3.
[0037] Reference Figure 1 The discharge pipe 4 is inclined and its upper end is connected to the storage vessel 1. The discharge pipe 4 is connected to the bottom of the storage vessel 1. A valve body 41 is provided on the discharge pipe 4, which is used to control the opening and closing of the discharge pipe 4. By controlling the valve body 41, the user can discharge the material at the bottom of the storage vessel 1 to the outside of the storage vessel 1 and re-grind it.
[0038] Reference Figure 2 The auger 22 includes a rotating shaft 221 and blades 222. The blades 222 are mounted on the rotating shaft 221, which is coaxially arranged inside the outer cylinder 21. A connector 214 is provided inside the outer cylinder 21 and is fixed to the upper end of the outer cylinder 21. The upper end of the rotating shaft 221 is rotatably connected to the connector 214, and the lower end of the rotating shaft 221 passes through the storage tank 1 and extends out. A drive mechanism 5 is located on the lower side of the storage tank 1 and is connected to the rotating shaft 221.
[0039] Reference Figure 1 The drive mechanism 5 includes a motor 51, two pulleys 52, and a belt 53. One pulley 52 is coaxially fixed on the output shaft of the motor 51, and the other pulley 52 is fixed on the rotating shaft 221. The belt 53 is sleeved on the two pulleys 52. The motor 51 drives the pulleys 52 to rotate, which in turn causes the rotating shaft 221 to rotate, thereby causing the auger 22 to rotate inside the outer cylinder 21.
[0040] Reference Figure 3 A fan 6 is installed at the top of the outer cylinder 21. The fan 6 is fixed to the top of the outer cylinder 21 and is located on the upper side of the connector 214 and the rotating shaft 221. The connector 214 is made of a rod and has ventilation holes. When the rotating shaft 221 rotates and drives the material to move, the fan 6 can work and cool the material. The fan 6 can also extract water vapor from the outer cylinder 21, keeping the material stable.
[0041] The implementation principle of this application embodiment is as follows: by setting a lifting auger mechanism 2 in the storage tank 1, the material in the storage tank 1 can enter the outer cylinder 21 and be lifted by the spiral auger 22. By setting a fan 6 on the top cover 11 and the top of the outer cylinder 21, the fan 6 can cool the material in the storage tank 1 and the fan 6 can discharge the residual water vapor in the storage tank 1, thereby achieving the purpose of drying the material.
[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
