[0036] Referring to Figure 3The cleaning structure 200 comprises a base 250, a swing driving component 230, a rotation driving component 240, a connecting rod 210 and a sprayer 220. The sprayer 220 is used for spraying clean water, is installed at the lower end of the connecting rod 210, is provided with a movable hole in the middle of the base 250, the connecting rod 210 is arranged in the movable hole, and the lower end of the connecting rod 210 extends into the reaction cavity 110. The swing driving component 230 is installed on the base 250, the output end of the swing driving component 230 is drivingly connected with the upper end of the connecting rod 210, the connecting rod 210 can be driven to swing in the vertical plane, so as to adjust the included angle between the connecting rod 210 and the horizontal plane, and adjust the spraying direction of the sprayer 220. The rotation driving component 240 is drivingly connected with the base 250, under the driving action of the rotation driving component 240, the base 250 can rotate around the center axis of the base 250, and the swing driving component 230 and the connecting rod 210 installed on the base 250 are also rotated, so that the sprayer 220 is rotated.

[0037] It can be understood that the clean water sprayed by the sprayer 220 can clean the inner wall of the reaction cavity 110, and flush the material adhered to the inner wall of the reaction cavity 110, so as to avoid that the fouling layer in the reaction cavity 110 affects the subsequent reaction heat exchange and material flow. The swing action and the rotation action of the sprayer 220 are matched with each other, so that the sprayer 220 can comprehensively spray and clean the inside of the reaction cavity 110, and avoid that the dead angle in the reaction cavity 110 is not cleaned.

[0038] In some embodiments, the connecting rod 210 is a telescopic rod which can be lengthened or shortened, and the cleaning structure 200 further comprises a telescopic driving component 270, the output end of the telescopic driving component 270 is drivingly connected with the telescopic rod, and the telescopic driving component 270 can drive the telescopic rod to lengthen or shorten. During the reaction of the reaction kettle 100, the telescopic driving component 270 is used to drive the telescopic rod to shorten, so as to avoid that the cleaning structure 200 affects the stirring and reaction of the material, and also avoid that the material pollutes or corrodes the sprayer 220. After the reaction is completed, the telescopic driving component 270 is used to drive the telescopic rod to lengthen, so that the lower end of the telescopic rod is close to the bottom of the reaction cavity 110, which is more conducive to the cleaning of the bottom of the reaction cavity 110, and avoids that the material is fouled at the bottom of the reaction cavity 110. During the cleaning process, the telescopic driving component 270 is used to control the telescopic rod to gradually shorten, so as to realize the cleaning of the inside of the reaction cavity 110 from bottom to top, and ensure that the inner wall of the entire reaction cavity 110 is clean and comprehensive.

[0039] In some embodiments, the telescopic rod comprises a fixed rod and a movable rod, the fixed rod is hollowly provided with a movable cavity which extends along the length direction of the fixed rod, and the movable rod is slidingly connected in the movable cavity and can extend out of the lower end of the movable cavity. The telescopic driving component 270 can be an electric cylinder, a pneumatic cylinder or the like, is installed on the fixed rod, and the output end of the telescopic driving component 270 is connected with the upper end of the movable rod, so as to control the movable rod to extend out of the movable cavity or to be retracted into the movable cavity.

[0040] It can be understood that the sprayer 220 needs to be equipped with a water pipe for supplying water from an external water supply device box to the sprayer 220. The sprayer 220 is a high-pressure nozzle that can increase the water flow pressure to form a high-pressure water jet, thereby better cleaning the inner wall of the reaction cavity 110.

[0041] In some embodiments, a water flow channel is hollowly formed in the movable rod and communicates with the sprayer 220. A hose is arranged in the movable cavity, one end of the hose is connected to the upper wall of the movable cavity, the lower end is connected to the movable rod and communicates with the water flow channel. An interface is arranged at the upper end of the fixed rod, and the interface is used for inserting the water pipe. When the telescopic rod performs telescopic action under the driving action of the telescopic driving part 270, the hose can ensure stable water supply of the sprayer 220, and also avoid damage of the water pipe following the sprayer 220.

[0042] In some embodiments, the telescopic driving part 270 is provided with a telescopic switch, which is arranged on the outer side of the fixed rod and is electrically connected with the telescopic driving part 270, so as to conveniently operate and control the telescopic action.

[0043] In some embodiments, the rotary driving part 240 includes a motor 241 and a transmission gear 242. The motor 241 is installed on the top of the reaction kettle 100, and the output shaft thereof is drivingly connected with the transmission gear 242. Under the driving action of the motor 241, the transmission gear 242 can rotate. The outer side wall of the base 250 is provided with a toothed structure, which is meshingly connected with the transmission gear 242. When the transmission gear 242 rotates, the base 250 can rotate with the transmission gear 242. The rotation direction of the base 250 is opposite to that of the transmission gear 242. The swing driving part 230 connected with the base 250, the connecting rod 210 and the sprayer 220 installed at the lower end of the connecting rod 210 can all rotate with the base 250.

[0044] It can be understood that when the included angle between the connecting rod 210 and the horizontal plane is an acute angle, the rotation of the base 250 can change the spraying direction of the sprayer 220, so that the sprayer 220 can realize 360° spraying in the plane where the sprayer 220 is located. When the swing action, the rotation action of the sprayer 220 and the telescopic action of the connecting rod 210 are matched with each other, the entire inside of the reaction cavity 110 can be sprayed, and overall cleaning can be realized.

[0045] It can be understood that the rotation speed of the base 250 is controlled by the rotation speed of the motor 241. The toothed structure and the transmission gear 242 should have a proper transmission ratio. The rotation of the sprayer 220 should not be too fast or too slow. If the rotation is too slow, the cleaning efficiency is low; if the rotation is too fast, the cleaning effect will be affected.

[0046] In some embodiments, the connecting rod 210 is connected with the hole wall of the movable hole through an elastic or soft material, so that the hole wall of the movable hole does not interfere with the swing of the connecting rod 210, and the base 250 can support the connecting rod 210.

The hole wall of the movable hole is arc-shaped. When the connecting rod 210 swings, the connecting ball 260 rotates in the movable hole. The hole wall of the movable hole can support the connecting rod 210, and the connecting rod 210 can smoothly swing under the driving action of the swing driving part 230.

[0048] In some embodiments, the swing driving part 230 is a pneumatic cylinder, the cylinder body of which is hinged with the base 250, and the output rod thereof is hinged with the upper end of the connecting rod 210. The swing action of the connecting rod 210 is realized through the extension and retraction of the output rod of the pneumatic cylinder, so as to adjust the spraying direction of the sprayer 220.

[0049] In some embodiments, the cleaning structure 200 is provided in plurality, and the plurality of cleaning structures 200 are arranged in the circumferential direction around the central axis of the reaction cavity 110. The cleaning efficiency of the inside of the reaction cavity 110 can be improved, and the inside of the reaction cavity 110 can be more comprehensively cleaned, avoiding the situation that local scaling occurs in dead angles.

[0051] In some embodiments, with reference to Figure 1 The bottom of the reaction kettle 100 is provided with a discharge port 112, which is communicated with the reaction cavity 110. A discharge valve is arranged at the discharge port 112, which is used to open or close the discharge port 112.

[0052] In the reaction synthesis process, if scaling is found on the inner wall of the reaction cavity 110, the discharge port 112 can be opened through the discharge valve, and the material can be discharged through the discharge port 112 at the bottom of the reaction kettle 100, and then the cleaning structure 200 is used to clean the inner wall of the reaction cavity 110 to remove the scaling. In the cleaning process, the discharge port 112 remains open, which can avoid the accumulation of water on the inner wall of the reaction cavity 110, thereby affecting the spraying and descaling of the inner wall of the reaction cavity 110 by the sprayer 220. After cleaning, the discharge port 112 is closed through the discharge valve, so as to avoid the material flowing out of the discharge port 112 during the reaction process and affecting the reaction synthesis.

[0053] In some embodiments, the bottom surface of the reaction cavity 110 is concave, and the evacuation port 112 is arranged at the middle of the bottom surface of the reaction cavity 110, i.e. the lowest end of the concave surface. In this way, the material or the cleaning water can flow along the bottom surface of the reaction cavity 110 to the evacuation port 112, so as to ensure that the material or the cleaning water in the reaction cavity 110 is completely evacuated.

[0054] In some embodiments, the reaction device further comprises a feeding pipe 130, which is connected to the upper end of the reaction kettle 100 and is inclined downwardly into the reaction cavity 110, and the lower ends of the feeding pipe 130 are arranged close to each other.

Since the lower ends of the feeding pipe 130 are arranged close to each other, the contact between the three materials can be accelerated, so as to improve the reaction rate, improve the production capacity and stabilize the product index. Figure 1 and Figure 2 It can be understood that the feeding pipe 130 is used to guide the material into the reaction cavity 110, and at least two feeding pipes are arranged so as to facilitate the mixing reaction of two or more materials. In this embodiment, the reaction device is used to synthesize iron phosphate, and the feeding pipe 130 is arranged in three, and the three feeding pipes 130 are respectively used to add raw materials, hydrogen peroxide and additives into the reaction cavity 110. Since the lower ends of the feeding pipe 130 are arranged close to each other, the contact between the three materials can be accelerated, so as to improve the reaction rate, improve the production capacity and stabilize the product index.

[0056] In some embodiments, the feeding pipe 130 is equipped with a metering pump, and the proportion and speed of the raw materials, hydrogen peroxide and additives entering the feeding pipe 130 are controlled by the metering pump. It can be understood that the purpose of synthesizing iron phosphate can be achieved by controlling the addition rate of the three materials, and the particle size index of the iron phosphate can be adjusted by controlling the addition rate of the additives.

[0057] In this embodiment, the side wall of the reaction kettle 100 is provided with an overflow port 111, which is arranged above the outlet end of the feeding pipe 130. After the material mixing reaction, the slurry flows out of the reaction cavity 110 through the overflow port 111 and is collected, and the slurry is aged by the upward fluid movement in the synthesis process.

[0058] It can be understood that the raw materials are continuously added into the reaction cavity 110 through the feeding pipe 130 and mixed, and the synthesized slurry flows out through the overflow port 111, so as to realize the continuous synthesis reaction of the material, improve the production capacity of a single reaction device, and avoid the problem that the index fluctuation between different batches of synthesized materials is too large.

[0059] In some embodiments, the reaction device further comprises a cooling flow channel and a heating flow channel. The cooling flow channel is used for flowing cooling medium to achieve the effect of cooling the reaction kettle 100. The heating flow channel is used for flowing heating medium to achieve the effect of increasing the temperature of the reaction kettle 100.

[0061] The heating flow channel can be arranged inside or outside the reaction kettle 100, and is provided with a heating inlet 170 and a heating outlet 160. The heating medium enters the heating flow channel from the heating inlet 170 and flows out through the heating outlet 160, and heat exchange is carried out between the heating medium and the reaction kettle 100 to achieve heating.

[0062] The cooling medium can be cooling water and the like; and the heating medium can be hot water, hot steam and the like.

In this way, the existing position of the reactant can be concentratedly heated or cooled.

[0065] In some embodiments, with reference to Figure 1 , the reaction device further comprises a temperature transmitter 113 arranged at the bottom of the reaction kettle 100. The temperature transmitter 113 is used to obtain the temperature of the material in the reaction kettle 100, so that the operator can adjust the temperature of the reaction kettle 100 through the cooling flow channel and the heating flow channel, and ensure that the reaction temperature in the reaction kettle 100 reaches the preset temperature.

[0066] The temperature transmitter 113 belongs to an instrument capable of converting a temperature variable into a transmittable output signal, including a sensor and a signal converter.

[0067] It can be understood that, with reference to Figure 1 The reaction device generally further includes a stirring component and a stirring driving component 121, an output end of the stirring driving component 121 is connected with the stirring component, and under the driving action of the stirring driving component 121, the stirring component can rotate in the reaction cavity 110 to realize the mixing and stirring of raw materials, so that the reaction is more comprehensive.

[0068] In some embodiments, with reference to Figure 1 The stirring component includes three layers of stirring blades 120, which are arranged in the reaction cavity 110 along the up-down direction, and can stir and mix the upper layer, middle layer and lower layer materials in the reaction cavity 110, thereby improving the reaction efficiency. The lower end of the feeding pipe 130 extends to the middle layer stirring blade 120, and the raw materials can be settled, lifted and stirred in the reaction cavity 110, so as to improve the reaction efficiency, improve the production capacity and stabilize the product index.

[0069] When the reaction device of the embodiment is used for iron phosphate synthesis reaction, the raw materials, hydrogen peroxide and additives are added into the reaction cavity 110 through the feeding pipe 130 in a preset ratio under the action of the metering pump, and are stirred and mixed by the stirring component. The slurry formed by the synthesis of the raw materials, hydrogen peroxide and additives in the reaction cavity 110 flows out through the overflow port 111 and is collected, and the slurry completes aging through the fluid movement from bottom to top in the synthesis process.

[0070] During the synthesis of the materials, the operator obtains the material temperature in the reaction kettle 100 through the temperature transmitter 113, and controls the material temperature in the reaction kettle 100 through the cooling flow channel and the heating flow channel. When the temperature is too high, the reaction kettle 100 is cooled by passing cooling medium into the cooling flow channel; when the temperature is too low, the reaction kettle 100 is heated by passing heating medium into the heating flow channel.
