Description

Technical Field

[0001] This utility model relates to the field of chemical technology, specifically to a distillation vessel for solvent recovery. Background Technology

[0002] In many industrial production fields involving solvent recycling, such as chemical, pharmaceutical, and coating industries, solvent recovery distillation kettles play a crucial role. By heating, evaporating, and condensing mixtures containing solvents in a distillation kettle, solvents can be effectively separated from other impurities or materials, achieving solvent recycling and reuse. This not only helps reduce production costs but also meets the requirements of environmental protection and sustainable resource development.

[0003] However, currently, the feeding process into the solvent recovery distillation vessel is mostly carried out manually by lifting the feeding bucket. This traditional feeding method has many obvious drawbacks:

[0004] Manually lifting material buckets requires operators to exert a great deal of physical strength, especially when dealing with large-capacity and heavy buckets. Frequent handling and lifting operations can easily lead to physical fatigue for operators, and over time may even cause physical injury, seriously affecting the health and work efficiency of operators.

[0005] When lifting a material bucket by hand, there is a risk of the bucket slipping or tipping over due to changes in a person's attention and physical strength. If this happens, on the one hand, it may cause material leakage, leading to pollution of the production site and increasing the cost and difficulty of subsequent cleanup; on the other hand, if the material has corrosive, toxic or other hazardous characteristics, it may also pose a serious threat to the personal safety of the operator and cause a safety accident.

[0006] When manually pouring materials into the distillation vessel, it is difficult to accurately control the flow rate and pouring position, which can easily lead to material splashing and uneven pouring. This not only affects the uniformity of material distribution in the distillation vessel, which is not conducive to the stable and efficient operation of subsequent distillation, but may also cause some material waste and increase production costs.

[0007] In summary, given the numerous problems associated with the existing manual loading method for solvent recovery distillation kettles, there is an urgent need for a new type of loading mechanism that can replace manual labor and achieve efficient, safe, and precise loading to meet the growing production demands and requirements for safe production and high-quality operation in the field of solvent recovery in industrial production. Utility Model Content

[0008] To address the aforementioned problems, this invention presents a distillation vessel for solvent recovery.

[0009] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0010] A distillation vessel for solvent recovery includes a base. Two columns are rotatably connected to the top wall of the base via a pin. A motor is mounted on the inner bottom wall of each column. A lead screw is locked to the output end of the motor via a coupling, and the top end of the lead screw is rotatably connected to the inner top wall of the column via a bearing. A connecting block is threaded onto the outer wall of the lead screw. A connecting rod is mounted on the inner end wall between the connecting blocks. The inner end wall of the connecting rod extends beyond the column and is provided with a connecting plate. A round rod is rotatably connected to the inner wall of the connecting plate via a bearing. A cylinder is mounted on the inner end between the round rods. A discharge pipe is mounted on the bottom wall of the cylinder. A valve is mounted on the outer wall of the discharge pipe. A tilting drive mechanism is mounted on the left end wall of the base.

[0011] Furthermore, the tilting drive mechanism includes a base plate, the top wall of which is rotatably connected to a hydraulic cylinder via a second pin seat, and the drive top of the hydraulic cylinder is rotatably connected to the left side wall of the column via a third pin seat.

[0012] Furthermore, the outer wall of the hydraulic cylinder is inclined.

[0013] Furthermore, an elongated hole is provided through the inner wall of the column.

[0014] Furthermore, the outer ring of the first bearing is fixedly connected to the inner wall of the column through the bearing seat, and the inner ring of the first bearing is interference-fitted with the outer wall of the lead screw.

[0015] The beneficial effects of this utility model are:

[0016] This utility model adopts an automated operation mode driven by power components such as motors and hydraulic cylinders. Compared with the traditional manual material bucket loading method, it greatly improves the loading speed. The manual material bucket loading method is limited by the physical strength and operation frequency of human beings, and the loading process is slow and easy to be interrupted. However, this device can quickly and continuously complete a series of operations from material filling to conveying to the distillation kettle according to the predetermined process. It can meet the continuous supply of materials required by the solvent recovery distillation kettle in a timely manner, effectively ensure the efficient and uninterrupted operation of the solvent recovery production process, and significantly improve the overall production efficiency.

[0017] Throughout the entire feeding process, this feeding mechanism ensures that the material remains in a safe and controllable state through the stable transmission and precise control of each component. This effectively prevents accidental material leakage, reduces the burden of cleaning up the production site, and alleviates a series of subsequent problems that may be caused by material leakage.

[0018] This device is automated, allowing operators to control the equipment from a relatively safe distance, away from potential hazards such as material leaks and splashes. This greatly ensures the personal safety of operators, significantly reduces the probability of accidents, and meets the requirements for safe production. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] See Figure 1-3As shown, a distillation vessel for solvent recovery includes a base 1. The top wall of the base 1 is rotatably connected to two columns 3 via a pin seat 2. A motor 4 is mounted on the inner bottom wall of the columns 3. The output end of the motor 4 is locked with a lead screw 5 via a coupling. The top end of the lead screw 5 is rotatably connected to the inner top wall of the columns 3 via a bearing 1. A connecting block 6 is threaded onto the outer wall of the lead screw 5. A connecting rod 7 is mounted on the inner end wall between the connecting blocks 6. The inner end wall of the connecting rod 7 extends out of the columns 3 and is provided with a connecting plate 8. A round rod 9 is rotatably connected to the inner wall of the connecting plate 8 via a bearing 2. A cylinder 10 is mounted on the inner end between the round rods 9. A discharge pipe 11 is mounted on the bottom end wall of the cylinder 10. A valve is mounted on the outer wall of the discharge pipe 11. A tilting drive mechanism is mounted on the left end wall of the base 1.

[0027] Furthermore, the tilting drive mechanism includes a base plate 12. The top wall of the base plate 12 is rotatably connected to a hydraulic cylinder 14 via a second pin seat 13. The drive top of the hydraulic cylinder 14 is rotatably connected to the left side wall of the column 3 via a third pin seat. The hydraulic cylinder 14 drives the column 3 to tilt the connecting rod 7, connecting plate 8, round rod 9, and cylinder 10 to the left, tilting the cylinder 10 to above the feed inlet of the distillation kettle. When the column 3 tilts, the cylinder 10 is always vertically positioned by rotating the bearing 2. The valve on the outer wall of the discharge pipe 11 is opened, and the material in the cylinder 10 is transported into the distillation kettle through the discharge pipe 11, completing the feeding operation of the distillation kettle.

[0028] Furthermore, the outer wall of the hydraulic cylinder 14 is inclined. The hydraulic cylinder 14 drives the column 3 to tilt the connecting rod 7, connecting plate 8, round rod 9 and cylinder 10 to the left, so as to move the cylinder 10 tilted above the feed inlet of the distillation kettle.

[0029] Furthermore, an elongated hole is provided through the inner wall of the column 3 for the connecting rod 7 to move up and down.

[0030] Furthermore, the outer ring of bearing one is fixedly connected to the inner wall of column 3 through bearing seat, and the inner ring of bearing one is interference-fitted to the outer wall of lead screw 5. The bearing one plays a fixing role for lead screw 5, which facilitates the rotation of lead screw 5 through bearing one.

Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0032] One specific application of this embodiment is:

[0033] In use, the device is installed on one side of the distillation vessel, which is placed between the base plates 12. The motor 4 drives the lead screw 5 to rotate, which in turn drives the connecting block 6 to move the connecting rod 7, connecting plate 8, round rod 9, and cylinder 10 upwards or downwards. The cylinder 10 is moved downwards to the bottom, and the material is poured into it. The motor 4 then drives the cylinder 10 upwards to the top. The hydraulic cylinder 14 drives the column 3 to tilt the connecting rod 7, connecting plate 8, round rod 9, and cylinder 10 to the left, moving the cylinder 10 tilted above the feed inlet of the distillation vessel. During the tilting movement, the cylinder 10 remains vertical due to the rotation of the bearing 2. The valve on the outer wall of the discharge pipe 11 is opened, and the material in the cylinder 10 is conveyed into the distillation vessel through the discharge pipe 11, completing the feeding operation of the distillation vessel.
