Technical Field

[0001] The utility model belongs to the technical field of reaction kettles, and in particular relates to a reaction kettle which is convenient for discharging materials. Background Art

[0002] The broad understanding of a reactor is a stainless steel container for physical or chemical reactions. The structural design and parameter configuration of the container are carried out according to different process conditions. The design conditions, process, inspection, manufacturing and acceptance must be based on relevant technical standards to achieve the heating, evaporation, cooling and low-speed mixing reaction functions required by the process.

[0003] The materials used in the reactor generally include liquid solvents and solid volumes. When powdered solid materials are added into the reactor, some of the powdered materials sometimes sink and accumulate at the bottom of the reactor, preventing the materials from fully reacting and affecting the subsequent discharging and discharge of materials. At the same time, the reactor generally has a negative pressure concentration function. During the negative pressure concentration process, crystals in the solvent precipitate and aggregate and accumulate to block the bottom of the reactor, seriously affecting the subsequent discharging and discharge of materials. Summary of the invention

[0004] In view of the above problems, the purpose of the utility model is to provide a reactor that is easy to discharge materials, so as to solve the problem that during the feeding and concentration process of the traditional reactor, the solid materials fed into the reactor or the precipitated materials are deposited and blocked at the discharge port, causing difficulty in discharging materials.

[0011] As a further improvement of the above technical solution: the bottom end of the auger is not higher than the bottom end of the circulation pipe.

[0012] The beneficial effect of this improvement is that under the rotation of the auger, the material in the tank body circulates through the reflux pipe, the circulation pipe and the tank body, thereby avoiding material sedimentation during the stirring process.

[0013] In order to effectively suck the materials in the tank;

[0014] As a further improvement of the above technical solution: the auger and the inner wall of the tee pipe are clearance-fitted.

[0015] The beneficial effect of this improvement is that the auger matched with the gap of the three-way pipe can effectively suck the material.

[0016] In order to prevent materials from entering the circulation pipe during discharge;

[0017] As a further improvement of the above technical solution: the regulating valve is a three-way valve structure.

[0018] The beneficial effect of this improvement is that by adjusting the valve path direction of the regulating valve, the port of the circulation pipe can be kept closed, thereby preventing materials from entering the circulation pipe during the discharge process.

[0021] The beneficial effect of this improvement is that the support member provides rotation support for the three-way pipe, thereby ensuring the stability of the rotation of the three-way pipe.

[0022] In order to ensure the stability of the support installation;

[0023] As a further improvement of the above technical solution: the two ends of the connecting plate are respectively connected to the inner wall of the three-way pipe and the outer side surface of the bearing seat.

[0024] The beneficial effect of this improvement is that the connecting plate can stably connect the supporting member as a whole to the three-way pipe.

[0025] In order to reduce the adverse effects of supports on material cutting;

[0026] As a further improvement of the above technical solution: the connecting plate is a flat plate structure, and is circumferentially arranged around the axis of the bearing.

[0027] The beneficial effect of this improvement is that the connecting plate of the flat plate structure can effectively reduce the adverse effects on material discharge while making the supporting member stably installed on the three-way pipe as a whole.

The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention. Example

[0035] like Figure 1—4 shows a reactor for easy discharge, comprising a tank body 1, wherein the bottom end of a stirring shaft 2 installed in the tank body 1 is connected to an auger 3, a discharge port at the bottom of the tank body 1 is connected to one end of a three-way pipe 4, the lower half of the auger 3 is installed inside the three-way pipe 4, the other two ends of the three-way pipe 4 are respectively connected to a discharge valve 5 and a circulation pipe 6, the other end of the circulation pipe 6 is connected to a reflux pipe 8 through a regulating valve 7, the bottom end of the reflux pipe 8 extends into the tank body 1, and the forward and reverse rotation of the reactor motor is controlled, that is, The rotating auger 3 can prevent the material from accumulating at the bottom of the tank body 1 during the material reaction process, and assist in the material discharge during the discharge process to prevent the material from blocking the discharge port. The bottom end position of the reflux pipe 8 is not higher than one-third of the tank depth of the tank body 1. The reflux pipe 8 can be immersed below the material liquid surface during the stirring process to effectively suck the material. The bottom end of the auger 3 is not higher than the bottom end of the circulation pipe 6. Under the rotation of the auger 3, the material in the tank body 1 circulates through the reflux pipe 8, the circulation pipe 6, and the tank body 1 to avoid the material from clogging the discharge port during the stirring process. During the process, material deposition occurs. The auger 3 and the inner wall of the three-way pipe 4 are clearance-matched. The auger 3 with clearance-matched with the three-way pipe 4 can effectively suck the material. The regulating valve 7 is a three-way valve structure. By adjusting the valve path direction of the regulating valve 7, the port of the circulation pipe 6 can be kept closed to prevent the material from entering the circulation pipe 6 during the discharge process. The inner wall of the three-way pipe 4 is installed with a support member 9, and the support member 9 is composed of a bearing seat 91, a bearing 92 and a connecting plate 93. The rod of the three-way pipe 4 is rotatably installed on the bearing 9 2, the support member 9 provides rotation support for the three-way pipe 4 to ensure the stability of the rotation of the three-way pipe 4. The two ends of the connecting plate 93 are respectively connected to the inner wall of the three-way pipe 4 and the outer side of the bearing seat 91. The connecting plate 93 can stably connect the support member 9 as a whole with the three-way pipe 4. The connecting plate 93 is a flat plate structure and is circumferentially arranged around the axis of the bearing 92. The connecting plate 93 with a flat plate structure can stably install the support member 9 on the three-way pipe 4 as a whole, which can effectively reduce the adverse effects on material discharge.

[0036] The working principle of the present technical scheme is as follows: before feeding, the operator starts the stirring motor of the reactor, and then adjusts the valve path of the regulating valve 7 so that the reflux pipe 8 is connected to the external air; when the stirring shaft 2 rotates forward under the drive of the motor, it drives the agitator and the auger 3 to rotate synchronously. At this time, the operator feeds solid materials into the interior of the tank body 1 through the feeding port. After the feeding is completed, the operator adjusts the valve path of the regulating valve 7 so that the reflux pipe 8 is connected to the circulation pipe 6. At this time, as the auger 3 rotates and draws, the solvent in the tank body 1 enters the circulation pipe 6 through the reflux pipe 8, and flows into the interior of the tank body 1 from bottom to top through the three-way pipe 4, effectively avoiding the deposition of materials at the bottom of the tank body 1 and blocking the discharge port during the mixing process; when discharging, the operator adjusts the valve path of the regulating valve 7 so that the reflux pipe 8 is connected to the external air, opens the discharge valve 5, and controls the stirring motor to reverse. At this time, the three-way pipe 4 reverses and pushes the materials in the tank body 1 downward, effectively avoiding the blocking of the materials at the discharge port of the tank body 1 during the discharging process.
