[0022] The present invention will be further described below with reference to the embodiments. Example

[0023] See also Figure 1-Figure 5The dosing assembly 5 includes a medicine box 51 fixedly mounted on the top of the support plate 2, a water pump 52 fixedly mounted on the top of the medicine box 51, a first connecting pipe 53 fixedly connected to the output end of the water pump 52, a third connecting pipe fixedly connected between the input end of the water pump 52 and the medicine box 51, a liquid medicine hopper 55 movably embedded in the card slot 31, a first liquid outlet pipe 56 fixedly connected to the bottom end of the liquid medicine hopper 55, a second liquid outlet pipe 57 fixedly connected to the bottom end of the first liquid outlet pipe 56, a liquid outlet valve 58 fixedly connected to the outer surface of the first liquid outlet pipe 56, a bucket cover 54 movably connected to the top of the liquid medicine hopper 55, and a second connecting pipe 59 fixedly connected between the second liquid outlet pipe 57 and the barrel cover 42. The first connecting pipe 53 passes through the bucket cover 54, and the first connecting pipe 53 passes through the bucket cover 54. The tube 53 passes through the opening 32, and the second liquid outlet pipe 57 is arranged above the barrel cover 42. A liquid level sensor is arranged inside the medicine liquid hopper 55. Under the action of the water pump 52, the liquid medicine in the medicine box 51 enters the medicine liquid hopper 55 through the first connecting pipe 53. There is no need for the operator to climb to a high place with the help of a ladder to add medicine. The liquid outlet valve 58 is opened. Under the action of gravity, the liquid medicine flows into the interior of the reaction barrel 4 in turn through the first liquid outlet pipe 56, the second liquid outlet pipe 57 and the second connecting pipe 59 to complete the addition of medicine. The liquid raw material is transmitted in a closed pipeline, reducing contact with the outside world. There is no need to open the barrel cover 42, which is convenient for protecting operators. The liquid level sensor is convenient for real-time monitoring of the liquid level in the medicine liquid hopper 55 to ensure that the liquid is kept within an appropriate range during the addition process.

[0024] The conveying assembly 6 includes a conveying box 62 arranged above the support seat 11, a first motor 61 fixedly connected to one end of the conveying box 62, a spiral conveying rod 63 fixedly connected to the output end of the first motor 61, a feeding channel 64 fixedly connected between the conveying box 62 and the barrel cover 42, and a feeding channel 65 fixedly connected to the conveying box 62 on the side away from the feeding channel 64. The feed channel 65 is movably connected with a connecting cover 651 inside the feed channel 65, the spiral conveying rod 63 passes through the conveying box 62, the first motor 61 is fixedly connected to the support seat 11, and the conveying box 62 is set to an inclined state. The solid medicine is poured into the feed channel 65, and the spiral conveying rod 63 is driven to rotate by the first motor 61. The spiral conveying rod 63 is convenient for effectively grasping and conveying solid medicine particles, preventing material from being blocked or accumulated during the conveying process, and facilitating the continuous and uniform advancement of the solid medicine along the conveying box 62. The solid medicine falls into the reaction barrel 4 through the feeding channel 64 during the conveying process.

[0025] A second motor 7 is fixedly installed on the top of the barrel cover 42, and a rotating rod 71 is fixedly connected to the output end of the second motor 7. The bottom end of the rotating rod 71 is fixedly connected to a connecting frame 711, and the top of the connecting frame 711 is fixedly connected to a scraper 7121. A connecting rod 712 is fixedly connected between the rotating rod 71 and the scraper 7121. The rotating rod 71 passes through the barrel cover 42 and is driven to rotate by the second motor 7. The rotation of the rotating rod 71 drives the connecting frame 711 and the connecting rod 712 to rotate, thereby driving the scraper 7121 to rotate, producing a certain stirring effect, which helps to increase the reaction rate of the drug.

[0026] The scraper 7121 contacts the inner wall of the reaction barrel 4, and the inner wall of the reaction barrel 4 is coated with a polytetrafluoroethylene coating. The contact between the scraper 7121 and the inner wall of the reaction barrel 4 effectively prevents the material from adhering to the barrel wall of the reaction barrel 4 during the reaction process, thereby reducing material waste. The polytetrafluoroethylene coating reduces wear and adhesion.

[0027] A discharge pipe 43 is fixedly connected to the outer surface of the reaction barrel 4 , and a discharge valve 431 is fixedly connected to the outer surface of the discharge pipe 43 . The discharge valve 431 is opened to discharge the reacted drug through the discharge pipe 43 .

[0028] A pressure gauge 8 and a pressure relief pipe 9 are provided on the top of the barrel cover 42. A pressure relief valve 91 is provided on the outer surface of the pressure relief pipe 9. The pressure gauge 8 is used to monitor the pressure changes inside the reaction barrel 4 in real time. The pressure relief valve 91 is used to control the pressure relief pipe 9. When the pressure inside the reaction barrel 4 exceeds the safety threshold, the excess gas or steam can be quickly released.

[0029] When in use, solid medicine is poured in through the feed channel 65, and the first motor 61 drives the spiral conveying rod 63 to rotate, so that the solid medicine is continuously and evenly pushed along the conveying box 62. During the conveying process, the solid medicine falls into the reaction barrel 4 through the feed channel 64. Under the action of the water pump 52, the liquid medicine in the medicine box 51 enters the medicine liquid hopper 55 through the first connecting pipe 53. There is no need for the operator to climb up to a high place with the help of a ladder to add medicine. The liquid outlet valve 58 is opened, and the liquid medicine passes through the first liquid outlet pipe 56, the second liquid outlet pipe 57 and the liquid outlet pipe 58 in turn under the action of gravity. The second connecting pipe 59 flows into the interior of the reaction barrel 4 to complete the dosing. The liquid raw material is transmitted in a closed pipeline, reducing contact with the outside world. There is no need to open the barrel cover 42, which is convenient for protecting the operator. The liquid level sensor is convenient for real-time monitoring of the liquid level in the liquid medicine bucket 55 to ensure that the liquid remains in an appropriate range during the dosing process. The second motor 7 drives the rotating rod 71 to rotate, and the rotation of the rotating rod 71 drives the connecting frame 711 and the connecting rod 712 to rotate, thereby driving the scraper 7121 to rotate, generating a certain stirring effect, which helps to increase the reaction rate of the drug.
