Description

Technical fields:

[0001] This utility model relates to the field of chemical equipment technology, and more specifically to a mixing reactor with a dust-collecting structure. Background technology:

[0002] A reaction vessel is a container used to realize physical or chemical reactions, mainly for liquid-phase reactions and multiphase reaction processes such as liquid-liquid, gas-liquid, liquid-solid, and gas-liquid-solid. Through structural design and parameter configuration, it can achieve functions such as heating, evaporation, cooling, and mixing, and is widely used in chemical, pharmaceutical, petroleum, and food industries.

[0003] In existing mixing reactors, materials are typically poured into the inner cavity of the reactor body, and then stirred and mixed by rotating the stirring shaft. However, after adding a certain amount of material, such as 3 kg, a separating agent needs to be added. Currently, the material must be weighed manually and poured into the inner cavity of the reactor body, which is very cumbersome. At the same time, there is no adsorption device at the discharge port of the reactor, which causes some exhaust gas to drift out when the material is discharged, and dust will float in the air, affecting the surrounding environment and resulting in poor environmental protection. Utility model content:

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a mixing reactor with a dust-collecting structure. When feeding, it can automatically sense the weight through a weighing sensor, eliminating the need to weigh the added material beforehand. Moreover, when discharging at the discharge end of the manually controlled valve, it can adsorb the surrounding air, thereby adsorbing the dust or gas generated during the discharge and reducing the impact on the surrounding environment.

[0005] The solution of this utility model to the aforementioned technical problem is:

[0006] A mixing reactor with a dust collection structure includes a mixing reactor body. Vertical support frames on the left and right sides of the mixing reactor body are fixed to the top surface of the same bottom fixing plate. Weighing sensors are fixed to the left and right front and rear parts of the bottom surface of the bottom fixing plate.

[0007] The bottom plate of the mixing reactor body is connected to a downward-extending discharge connector, and the bottom end of the discharge connector is connected to a manual control valve, with the discharge end of the manual control valve pointing vertically downward.

[0008] A horizontal connecting pipe is provided above the rear of the mixing reactor body. One end of a gooseneck pipe is connected to the vent connector at the bottom of the horizontal connecting pipe, and the other end of the gooseneck pipe is connected to a suction connector. The suction connector is facing the discharge end of the manual control valve.

[0009] A separator connector is connected to the front wall of the mixing reactor body. A baffle is fixed to the front end of the separator connector by bolts. A sealing ring is clamped between the baffle and the edge of the front end of the separator connector. The baffle covers the front end of the central through hole of the separator connector. The central through hole of the separator connector communicates with the internal stirring chamber of the mixing reactor body.

[0010] The suction connector includes a cylindrical connecting tube and a tapered suction port formed at the front end of the cylindrical connecting tube.

[0011] A transverse connecting shaft is provided at the middle of the front end of the cylindrical connecting tube. The two ends of the transverse connecting shaft are fixed to the inner side wall of the front part of the cylindrical connecting tube. Two semi-circular cover plates are located in the front end of the cylindrical connecting tube. The two semi-circular cover plates form a circular cover plate and cover the front end of the cylindrical connecting tube.

[0012] Movable rings are fixed on the adjacent sides of the rear walls of the two semi-circular cover plates. All the movable rings are staggered, and the transverse connecting shaft is inserted into the central through hole of all the movable rings.

[0013] A middle support plate is provided directly below the transverse connecting shaft, and both ends of the middle support plate are fixed to the inner sidewall of the cylindrical connecting tube.

[0014] One end of a reset spring is fixed to the middle of the left and right sides of the intermediate support plate, and the other end of the reset spring is fixed to the middle of the rear wall of the corresponding semi-circular cover plate.

[0015] The outstanding effect of this utility model is:

[0016] Compared with existing technologies, it can adsorb the surrounding air when discharging material at the discharge end of the manually controlled valve, thereby adsorbing the dust or gas generated during the discharge and reducing the impact on the surrounding environment. At the same time, when feeding material, it can automatically sense the weight through a weighing sensor, eliminating the need to pre-weigh the material, reducing operation steps and improving processing efficiency.

[0022] For example, see below. Figures 1 to 5 As shown, a mixing reactor with a dust collection structure includes a mixing reactor body 10. The vertical support frames on the left and right sides of the mixing reactor body 10 are fixed to the top surface of the same bottom fixing plate 11. Weighing sensors 12 are fixed to the left and right front and rear parts of the bottom surface of the bottom fixing plate 11. The weighing sensors 12 are electrically connected to the control host via electrical connection wires. At the same time, a display screen is installed on a nearby wall or frame. The display screen is electrically connected to the control host. The control host can display the value sensed by the weighing sensors 12 on the display screen. In addition, the control host can set a weight reminder. For example, the control host can also be electrically connected to a speaker. When the sensed value reaches the set value, the corresponding value is displayed on the display screen, and an sound is emitted through the speaker to realize the reminder.

[0023] The bottom plate of the mixing reactor body 10 is connected to a downwardly extending discharge connector 13, and the bottom end of the discharge connector 13 is connected to a manual control valve 14, with the discharge end of the manual control valve 14 pointing vertically downward.

[0024] A horizontal connecting pipe 20 is located above the rear of the mixing reactor body 10. One end of a gooseneck pipe 21 is connected to a vent connector at the bottom of the horizontal connecting pipe 20, and the other end of the gooseneck pipe 21 is connected to a suction connector 30, which faces the discharge end of the manual control valve 14. The vent end of the horizontal connecting pipe 20 is connected to a control valve at the suction port of the dust removal equipment via a connecting pipe. This is a conventional structure and will not be described in detail here, nor is it shown in the attached drawings.

[0025] Furthermore, a release agent connector 15 is connected to the front wall plate of the mixing reactor body 10, and a baffle 16 (attached) is fixedly connected to the front end face of the release agent connector 15 by bolts. Figure 1(omitted from the image) A sealing ring is clamped between the edge of the front end face of the baffle 16 and the separator connector 15. The baffle 16 covers the front end of the central through hole of the separator connector 15, which communicates with the internal stirring chamber of the mixing reactor body 10. In use, the baffle 16 is removed, and then the separator delivery pipe is connected. A solenoid valve is connected to the inlet of the separator delivery pipe, and the other end of the solenoid valve is connected to the outlet of the separator delivery pump. The connection pipe connected to the inlet of the delivery pump extends into the separator tank. When the four weighing sensors 12 sense a value of 3kg (this is set to a single full load of 3kg, which allows for separator addition and stirring), the separator is allowed to enter the inner cavity of the mixing reactor body 10 by running the delivery pump and opening the solenoid valve. After the addition is completed, the solenoid valve is closed. The solenoid valve, delivery pump, etc. are all conventional structures and will not be described in detail here, nor are they shown in the attached figures.

[0026] Furthermore, the discharge end of the manual control valve 14 is connected to a discharge pipe 1. It can be a bag-type discharge pipe.

[0027] Furthermore, the suction connector 30 includes a cylindrical connecting tube portion 31 and a conical suction port 32 formed at the front end of the cylindrical connecting tube portion 31. A grip portion is fixed on the outer wall of the conical suction port 32, which can be manually gripped to adjust the position of the conical suction port 32. Since it is a gooseneck tube 21, it can be moved to the corresponding position as needed for positioning, which is very convenient.

[0028] Furthermore, a transverse connecting shaft 33 is provided at the middle of the front end of the cylindrical connecting cylinder 31. The two ends of the transverse connecting shaft 33 are fixed on the inner side wall of the front part of the cylindrical connecting cylinder 31. Two semi-circular cover plates 34 are located in the front end of the cylindrical connecting cylinder 31. The two semi-circular cover plates 34 form a circular cover plate and cover the front end of the cylindrical connecting cylinder 31.

[0029] Each of the two semi-circular cover plates 34 has a movable ring 35 fixed on one side of its rear wall. All the movable rings 35 are staggered, and the transverse connecting shaft 33 is inserted into the central through hole of all the movable rings 35.

[0030] Furthermore, an intermediate support plate 36 is provided directly below the transverse connecting shaft 33, and both ends of the intermediate support plate 36 are fixed to the inner sidewall of the cylindrical connecting tube 31.

[0031] One end of a return spring 37 is fixed to the middle of the left and right sides of the intermediate support plate 36, and the other end of the return spring 37 is fixed to the middle of the rear wall of the corresponding semi-circular cover plate 34.

[0032] Furthermore, an annular limiting ring 321 is formed on the inner sidewall at the rear end of the conical air intake 32, and the front sidewalls of the two semi-circular cover plates 34 press against the rear end surface of the annular limiting ring 321.

[0033] Furthermore, a feed connection cylinder 2 is connected to the top plate of the mixing reactor body 10, and a feed connector is connected to the middle of the top plate of the feed connection cylinder 2.

[0034] In this embodiment, the material to be mixed is fed into the internal stirring chamber of the mixing reactor body 10 through the feed connector 2. When the weight reaches the set value (sensed by the weighing sensor 12, displayed on the screen, and accompanied by an audible alarm), the solenoid valve and the delivery pump are opened to inject a separating agent into the inner cavity of the mixing reactor body 10. After a certain amount has been added, the solenoid valve and the delivery pump are closed, and the stirring shaft in the mixing reactor body 10 rotates to stir the material inside, achieving a mixing reaction. Once stirring is complete, the material is discharged by manually opening the manual control valve 14. A receiving box can be placed below the discharge point to receive the material.

[0035] When receiving material, the control valve at the horizontal connecting pipe 20 is opened to achieve air intake, thereby adsorbing the air around the discharge point, so that the gas and dust coming out during discharge are adsorbed.

[0036] The conical air inlet 32 ​​has a gripping part fixed on its outer wall. By gripping the gripping part, the gooseneck tube 21 can be bent, thereby changing the position of the conical air inlet 32.

[0037] When it is inhaling air, the two semi-circular cover plates 34 fold backward, and the corresponding return spring 37 is compressed to achieve air intake. When it is not inhaling air, the two semi-circular cover plates 34 can be flipped forward and returned to their original position by the elastic reset of the return spring 37, so that the two semi-circular cover plates 34 form a circle. The front wall surface of the two semi-circular cover plates 34 presses against the rear end surface of the annular limiting ring 321, covering the rear end of the conical air intake 32, so that dust and other particles in the gooseneck tube 21 will not flow back out.

[0038] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
