Description

Technical Field

[0001] This utility model belongs to the technical field of feeding devices, and specifically relates to a feeding device for a synthesis reactor. Background Technology

[0002] In the process of synthesizing materials, materials need to be added to the interior of the synthesis reactor. The feeding device can precisely control the amount of each raw material added to ensure the accuracy and consistency of the reaction conditions. Most existing feeding devices are set up with multiple feed hoppers at the top of the synthesis reactor to transport materials into the interior of the synthesis reactor for mixing. However, in this method, the materials enter the interior of the synthesis reactor directly through the feed hoppers without being premixed before entering the synthesis reactor. Since there are many materials to be mixed inside the synthesis reactor, it takes a long time for the materials inside the reactor to be mixed evenly, which prolongs the mixing time and increases production costs.

[0003] For example, the utility model patent with announcement number CN209155793U discloses a novel automatic feeding device for a synthesis reactor. In the technical solution of this patent, the upper surface of the synthesis reactor is provided with feeding hoppers such as a catalyst inlet, a funnel feeding hopper, and an auxiliary material feeding hopper. The materials to be mixed are respectively transported to the interior of the synthesis reactor through the feeding hoppers for mixing. However, in this method, the materials to be mixed are directly transported to the interior of the synthesis reactor through the feeding hoppers. The materials cannot be pre-mixed before being put into the interior of the synthesis reactor. Since there are many materials to be mixed inside the synthesis reactor, it takes a long time for the synthesis reactor to mix the materials evenly, which prolongs the production cycle and reduces production efficiency. Utility Model Content

[0004] In view of this, the present invention addresses the shortcomings of the prior art by providing a synthesis reactor feeding device, which can not only feed materials into the synthesis reactor through the feeding component, but also premix the materials through the stirring component to improve the uniformity and efficiency of the reaction.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a synthesis reactor feeding device, including a synthesis reactor, a feeding component is provided at the upper end of the synthesis reactor, a baffle plate is provided at the upper end of the synthesis reactor, a discharge hole is opened in the middle of the baffle plate, a discharge hopper is provided at the lower end of the discharge hole, a discharge valve is provided at the discharge hopper, a premixing cavity is formed between the top wall of the synthesis reactor and the baffle plate, a rotating column is rotatably provided in the middle of the synthesis reactor, a stirring element one is provided at one end of the rotating column located inside the premixing cavity, and a stirring element two is provided on the outer arc surface of the other end away from the premixing cavity.

[0006] As a further improvement of this utility model, the feeding assembly includes a feeding hopper 1 located on the upper left side of the synthesis reactor, a flow meter being installed at the feeding hopper 1, an auxiliary material feeding hopper being installed at the upper right side of the synthesis reactor, a scale line being installed on the outer surface of the auxiliary material feeding hopper, a catalyst feeding hopper being installed on the right side of the auxiliary material feeding hopper, and a feeding valve being installed at the lower end of the feeding hopper 1, the auxiliary material feeding hopper, and the catalyst feeding hopper.

[0007] As a further improvement of this utility model, the stirring component includes several connecting plates disposed at one end of the rotating column located in the premixing chamber. A stirring rod is rotatably disposed at the end of each connecting plate away from the rotating column. Several stirring rollers are disposed at the lower end of each stirring rod. A driving component for driving the stirring rod to rotate is disposed at the upper end of the synthesis vessel. The driving component includes a mounting box disposed at the top of the synthesis vessel. A motor is fixedly disposed inside the mounting box. The output end of the motor is connected to the rotating column through a coupling. A gear is disposed at the upper end of each stirring rod. An external gear ring that meshes with the gear is fixedly disposed on the upper side wall of the synthesis vessel through a support rod.

[0008] As a further improvement of this utility model, the stirring component 2 includes a plurality of stirring rollers 2 disposed on the outer arc surface at the lower end of the rotating column.

[0009] As a further improvement of this utility model, a discharge port is provided at the bottom of the synthesis reactor, and a discharge valve is provided at the discharge port.

[0010] As a further improvement of this utility model, a fixing ring is provided at the lower end of the synthesis reactor, and several supporting bases are evenly provided at the lower end of the fixing ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Firstly, by setting up a premixing chamber and starting the motor, the motor drives the rotating column to rotate, which in turn drives the connecting plate to rotate. The stirring rod at the end of the connecting plate then rotates, and the gear at the upper end of the stirring rod rotates under the action of the external gear ring, which in turn drives the stirring rod to rotate. This causes the stirring roller to rotate while rotating around the rotating column, thus premixing the materials, reducing the uneven distribution of raw materials in the synthesis reactor, avoiding excessively high or low local concentrations, and improving the uniformity and efficiency of the reaction.

[0013] Secondly, by setting up feed valves, each feed valve can be controlled independently, and can be opened or closed according to the reaction needs, so as to achieve precise management of different raw materials.

[0014] Thirdly, a flow meter is installed at one point in the feed hopper. The flow meter can monitor the amount of material fed into the feed hopper in real time, ensuring that the amount of each raw material fed is accurate and controllable.

[0015] Fourth, the bottom of the synthesis reactor is equipped with a discharge port, and a discharge valve is installed at the discharge port. The discharge valve can precisely control the discharge speed and amount to ensure the uniform discharge of reaction products and avoid excessive or insufficient discharge.

Detailed Implementation

[0022] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0023] like Figure 1 , 2As shown in Figure 3, a synthesis reactor feeding device includes a synthesis reactor 101. A feeding assembly is provided at the upper end of the synthesis reactor 101. A baffle plate 102 is provided at the upper end of the synthesis reactor 101. A discharge hole is opened in the middle of the baffle plate 102. A discharge hopper 103 is provided at the lower end of the discharge hole. A discharge valve 104 is provided at the discharge hopper 103. A premixing chamber is formed between the top wall of the synthesis reactor 101 and the baffle plate 102. By setting the premixing chamber, materials can be added to the interior of the premixing chamber for preliminary mixing. A rotating column 201 is rotatably arranged in the middle of the synthesis reactor 101. A stirring element one is provided at one end of the rotating column 201 located inside the premixing chamber, and a stirring element two is provided on the outer arc surface of the end away from the premixing chamber.

[0024] like Figure 1 , 4 As shown, the feeding assembly includes a feed hopper 202 located on the upper left side of the synthesis reactor 101, a flow meter 203 located at the feed hopper 202, an auxiliary material feed hopper 204 located on the upper right side of the synthesis reactor 101, a scale line 205 located on the outer surface of the auxiliary material feed hopper 204, and a catalyst feed hopper 206 located on the right side of the auxiliary material feed hopper. Feed valves 207 are located at the lower ends of the feed hopper 202, the auxiliary material feed hopper 204, and the catalyst feed hopper 206. Each feed valve 207 can be independently controlled and opened or closed according to the reaction requirements to achieve precise management of different raw materials.

[0025] like Figure 2 , 3 As shown, the stirring component includes several connecting plates 301 disposed at one end of the rotating column 201 located in the premixing chamber. A stirring rod 302 is rotatably mounted on the end of each connecting plate 301 away from the rotating column 201. Several stirring rollers 303 are disposed at the lower end of each stirring rod 302. A driving component for driving the stirring rods 302 to rotate is disposed at the upper end of the synthesis vessel 101. The driving component includes a mounting box 304 disposed at the top of the synthesis vessel 101. A motor 305 is fixedly disposed inside the mounting box 304. The output end of the motor 305 is connected to the rotating column 201 via a coupling. The upper end of each stirring rod 302... A gear 306 is provided, and an external gear ring 307 that meshes with the gear 306 is fixed on the upper side wall of the synthesis kettle 101 by a support rod. When the motor 305 is started, the motor 305 drives the rotating column 201 to rotate. The rotating column 201 drives the connecting plate 301 to rotate, and the stirring rod 302 at the end of the connecting plate 301 rotates accordingly. The gear 306 at the upper end of the stirring rod 302 rotates under the action of the external gear ring 307, which in turn drives the stirring rod 302 to rotate. As a result, the stirring roller 303 rotates on its own axis while rotating around the rotating column 201, which enhances the fluidity of the material and improves the premixing efficiency.

[0026] like Figure 3As shown, the stirring component 2 includes several stirring rollers 308 disposed on the outer arc surface of the lower end of the rotating column 201. The motor 305 drives the rotating column 201 to rotate, and the rotating column 201 drives the stirring rollers 308 to rotate, thereby stirring and mixing the materials inside the synthesis kettle 101.

[0027] like Figure 1 , 4 As shown, the bottom of the synthesis reactor 101 is provided with a discharge port 105, and a discharge valve 106 is provided at the discharge port 105.

[0028] like Figure 1 , 4 As shown, a fixing ring 108 is provided at the lower end of the synthesis vessel 101, and several supporting bases 107 are evenly provided at the lower end of the fixing ring 108.

[0029] In use, first open the feed valve 207 at feed hopper 202 to pour the material into the premixing chamber through feed hopper 202. The flow meter 203 detects the amount of material entering. When the appropriate amount of material is reached, close the feed valve 207 at feed hopper 206. Then, open the feed valves 207 at auxiliary material feed hopper 204 and catalyst feed hopper 206 respectively, and pour in a certain amount of auxiliary material and catalyst. Start the motor 305, which drives the rotating column 201 to rotate. The rotating column 201 then drives the connecting plate 301 to rotate. When the stirring column on the connecting plate 301 is moved, the gear 306 at the upper end of the stirring column rotates under the action of the external gear ring 307, which in turn drives the stirring rod 302 to rotate, so that the stirring roller 303 rotates on its own axis while rotating around the rotating column 201, so as to premix the material and enhance the flowability of the material. Then the discharge valve 104 is opened, and the premixed material enters the interior of the synthesis kettle 101. The rotating column 201 drives the stirring roller 308 to rotate, thereby stirring and mixing the material inside the synthesis kettle 101.
