Description

Technical Field

[0001] This utility model relates to the field of cosolvent technology, and in particular to a cosolvent production apparatus for methanol gasoline. Background Technology

[0002] Methanol gasoline co-solvent is a new type of environmentally friendly fuel additive product, composed of base gasoline, methanol, and related additives. The key technology of methanol gasoline lies in the technical level and quality control of the co-solvent. The technological solubility of the methanol gasoline co-solvent is the soul that determines the excellent quality of blended methanol gasoline. The production process of methanol gasoline using co-solvent requires mixing and stirring various raw materials.

[0003] Currently, most existing mixing and stirring devices are not sealed during operation. During the mixing process, a large amount of volatile organic solvents will evaporate, which can easily form an explosive mixture of gases, posing a serious safety hazard. At the same time, solvent evaporation and leakage will pollute the working environment and endanger the health of workers. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a device for producing a cosolvent for methanol gasoline.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a methanol gasoline cosolvent production device, including a support frame, a stirring tank is arranged on the support frame, an output pipe is connected to the bottom of the stirring tank, an output solenoid valve is arranged on the output pipe, an exhaust pipe is connected to the upper part of the side wall of the stirring tank, an exhaust solenoid valve is arranged on the exhaust pipe, the exhaust pipe is connected to an external gas treatment device, a stirring assembly is arranged inside the stirring tank, a plurality of feeding assemblies are arranged on the top of the stirring tank, the feeding assembly includes a mounting frame arranged on the top of the stirring tank, a receiving cylinder is arranged on the mounting frame, a feeding pipe is connected to the bottom of the receiving cylinder, the lower end of the feeding pipe passes through the top of the stirring tank and communicates with the stirring tank, a first solenoid valve is arranged on the feeding pipe, an inlet pipe is arranged on the top of the receiving cylinder, and a metering pump is arranged on the inlet pipe.

[0006] By adopting the above technical solution, which includes a support frame, mixing tank, exhaust pipe, mixing assembly, and feeding assembly, production begins with connecting containers containing various raw materials to their corresponding inlet pipes. A metering pump precisely delivers each raw material to its designated container at the required dosage. Next, the first solenoid valve on the feeding pipe for the material to be added first is opened, allowing that material to enter the mixing tank. Subsequently, when other raw materials need to be added, the first solenoid valve on the corresponding material's feeding pipe is opened, allowing the material to be added to the mixing tank. The mixing assembly then stirs the raw materials in the mixing tank, forming a co-solvent. After stirring is complete, the output solenoid valve is opened to discharge the co-solvent. The feeding and stirring processes are conducted in a sealed environment, preventing the large-scale evaporation of volatile organic solvents, thereby eliminating safety hazards and reducing health risks to workers.

[0007] Furthermore, the top of the container is connected to an air inlet pipe, and several of the air inlet pipes are connected by a connecting pipe, which is connected to an external air source.

[0008] By adopting the above technical solution, an air inlet pipe and a connecting pipe are installed. During the mixing process, when subsequent raw materials need to be added, the exhaust solenoid valve and the first solenoid valve for the corresponding raw material are opened. Then, air is supplied to the connecting pipe through an external air source, allowing the gas to enter the container and discharge the raw materials. This prevents the volatile mixed gas in the mixing tank from flowing back into the container and avoids contamination of the raw materials entering the container. After the raw materials enter the container, excess gas is discharged from the exhaust pipe.

[0009] Furthermore, a second solenoid valve is installed on the feed pipe located between the metering pump and the receiving cylinder.

[0010] By adopting the above technical solution and setting a second solenoid valve, the second solenoid valve closes after the metering pump adds raw materials into the container, thus avoiding the impact of subsequent operations on the metering pump.

[0011] Furthermore, the outer wall of the container cylinder has vertically arranged strip-shaped holes, and a glass plate is placed inside the strip-shaped holes. Several scale lines are vertically spaced on the outer wall of the container cylinder next to the glass plate.

[0012] By adopting the above technical solution, and setting up a strip-shaped hole, a glass plate, and graduation lines, staff can observe the liquid level of the raw materials in the container through the glass plate and judge the volume of the raw materials in the container according to the graduation lines, thereby further ensuring the accuracy of the raw material volume and guaranteeing the quality of the cosolvent.

[0013] Furthermore, the stirring assembly includes a rotating shaft that is vertically rotatably disposed inside the stirring tank, a plurality of stirring blades being disposed on the rotating shaft, and a drive motor being vertically disposed on the top surface of the stirring tank, the output shaft of the drive motor being downward and connected to the rotating shaft.

[0014] By adopting the above technical solution, a rotating shaft, stirring blades, and a drive motor are set up. The drive motor drives the rotating shaft to rotate, which in turn drives several stirring blades to rotate and stir the raw materials in the mixing tank.

[0015] Furthermore, a rotating hole is provided in the middle of the top surface of the mixing tank, the upper end of the rotating shaft is rotatably connected to the rotating hole, and a rotating ring is rotatably provided at the lower end of the rotating shaft. Several connecting rods that are connected to the inner wall of the mixing tank are arranged circumferentially on the rotating ring.

[0016] By adopting the above technical solution, and setting up rotating holes, rotating rings, and connecting rods, the stability of the rotating shaft is ensured.

[0017] Furthermore, a fixing frame is provided on the top surface of the receiving cylinder, and the fixing frame is connected to the metering pump.

[0018] In summary, this utility model has the following beneficial effects: This application includes a support frame, a mixing tank, an exhaust pipe, a mixing assembly, and a feeding assembly. During production, firstly, the storage containers containing various raw materials are connected to their corresponding inlet pipes. A metering pump precisely delivers each raw material to its corresponding container according to the required dosage. Next, the first solenoid valve on the feeding pipe for which the raw material needs to be added is opened, allowing that raw material to enter the mixing tank. Subsequently, when other raw materials need to be added, the first solenoid valve on the corresponding raw material's feeding pipe is opened, allowing the raw material to be added to the mixing tank. The mixing assembly stirs the raw materials in the mixing tank, forming a co-solvent. After stirring is complete, the output solenoid valve is opened to discharge the produced co-solvent. Both the feeding and stirring processes are conducted in a sealed state, preventing the large-scale evaporation of volatile organic solvents, thereby eliminating safety hazards and reducing harm to the health of workers.

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] like Figure 1-3 As shown in the illustration, this application discloses a methanol gasoline cosolvent production apparatus, including a support frame 10, a stirring tank 11, a stirring assembly 40, and a feeding assembly 50. The stirring tank 11 is mounted on the support frame 10, and an output pipe 20 is connected to the bottom of the stirring tank 11. An output solenoid valve 21 is installed on the output pipe 20 to control the discharge of cosolvent from the stirring tank 11. An exhaust pipe 30 is connected to the upper part of the side wall of the stirring tank 11, and an exhaust solenoid valve 31 is installed on the exhaust pipe 30. The exhaust pipe 30 is connected to an external gas treatment device for treating the gas discharged from the exhaust pipe 30. The stirring assembly 40 is installed inside the stirring tank 11 to stir the raw materials inside the stirring tank 11. There are several feeding assemblies 50, all of which are located at the top of the stirring tank 11.

[0025] The feeding assembly 50 includes a mounting bracket 51 mounted on the top of the mixing tank 11. A receiving cylinder 52 is mounted on the mounting bracket 51, and a feeding pipe 53 is connected to the bottom of the receiving cylinder 52. The lower end of the feeding pipe 53 passes through the top of the mixing tank 11 and connects to it. A first solenoid valve 54 is mounted on the feeding pipe 53. An inlet pipe 55 is mounted on the top of the receiving cylinder 52, and a metering pump 56 is mounted on the inlet pipe 55. During production, firstly, storage containers containing various raw materials are connected to their corresponding inlet pipes 55. The metering pump 56 precisely delivers each raw material to its corresponding receiving cylinder 52 according to the required dosage. Next, the first solenoid valve 54 on the feeding pipe 53 of the raw material to be added is opened, allowing that raw material to enter the mixing tank 11. Afterward, when other raw materials need to be added, the first solenoid valve 54 on the corresponding raw material's feeding pipe 53 is opened to add the raw material to the mixing tank 11. The mixing assembly 40 agitates the raw materials in the mixing tank 11, forming a co-solvent. After stirring is complete, open the output solenoid valve 21 to discharge the prepared co-solvent. The feeding and stirring processes are conducted in a sealed state to prevent the large-scale evaporation of volatile organic solvents, thereby eliminating safety hazards and reducing health risks to workers. A fixing frame 523 is installed on the top surface of the receiving cylinder 52, which is connected to the metering pump 56 to ensure the stable installation of the metering pump 56.

[0026] Specifically, an air inlet pipe 57 is connected to the top of the container 52. Several air inlet pipes 57 are connected by a connecting pipe 58, which is connected to an external air source. During the mixing process, when subsequent raw materials need to be added, the exhaust solenoid valve 31 and the corresponding first solenoid valve 54 are opened. Then, air is supplied to the connecting pipe 58 through the external air source, allowing the gas to enter the container and discharge the raw materials. This prevents the volatile mixed gas in the mixing tank 11 from flowing back into the container and contaminating the raw materials entering the container. After the raw materials enter the container, excess gas is discharged from the exhaust pipe 30, and then the exhaust solenoid valve 31 is closed. A second solenoid valve 59 is installed on the feed pipe 53 located between the metering pump 56 and the container 52. After the metering pump 56 adds raw materials to the container, the second solenoid valve 59 is closed to prevent subsequent operations from affecting the metering pump 56. An airflow check valve (not shown in the figure) is provided at one end of the air inlet pipe 57 near the container 52. When it is necessary to supply air into the container 52, the corresponding airflow check valve is opened to prevent the volatile organic solvents in the container 52 from flowing to each other through the air inlet pipe 57.

[0027] During setup, the outer wall of the container 52 has vertically arranged strip-shaped holes, and a glass plate 521 is placed inside the strip-shaped holes. Several scale lines 522 are vertically spaced on the outer wall of the container 52 next to the glass plate 521. The staff can observe the liquid level of the raw material in the container through the glass plate 521 and judge the volume of the raw material in the container according to the scale lines 522, so as to further ensure the accuracy of the raw material volume and ensure the quality of the cosolvent.

[0028] In a specific configuration, the stirring assembly 40 includes a vertically rotatable shaft 41 within the stirring tank 11, with several stirring blades 42 mounted on the shaft 41. A drive motor 43 is vertically mounted on the top surface of the stirring tank 11, with its output shaft pointing downwards and connected to the shaft 41. The drive motor 43 drives the shaft 41 to rotate, causing the stirring blades 42 to rotate and stir the raw materials within the stirring tank 11. A rotating hole is provided in the center of the top surface of the stirring tank 11, with the upper end of the shaft 41 rotatably connected to the hole. A rotary seal is also provided between the shaft 41 and the hole. A rotating ring 44 is rotatably mounted on the lower end of the shaft 41, with several connecting rods 45 spaced circumferentially around the ring 44 and connected to the inner wall of the stirring tank 11 to ensure the stability of the shaft 41's rotation.

[0029] The operating principle of the methanol gasoline cosolvent production device in this embodiment is as follows: During production, the storage containers containing various raw materials are first connected to the corresponding inlet pipes 55. A metering pump 56 precisely delivers each raw material to the corresponding container 52 according to the required dosage. After delivery, the second solenoid valve 59 is closed. When raw materials need to be added, the exhaust solenoid valve 31 and the corresponding first solenoid valve 54 are opened. Then, an external gas source supplies gas into the connecting pipe 58, allowing the gas to enter the container and discharge the raw materials. The drive motor 43 is started to drive the rotating shaft 41 to rotate, which in turn drives several stirring blades 42 to stir the raw materials in the stirring tank 11, forming a cosolvent. After stirring is complete, the output solenoid valve 21 is opened to discharge the produced cosolvent.

[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
