Description

Technical Field

[0001] The present invention belongs to drying equipment, and particularly relates to an environmental protection drying equipment and a method thereof. Background Art

[0002] Environmental protection drying equipment is a key equipment for realizing material dehydration, solvent recovery and reducing pollutant emissions. With the increasingly strict environmental protection regulations, high-efficiency energy-saving and low-emission drying technologies have become a necessity in the high-efficiency energy-saving or energy-saving and environmental protection industries. However, the existing drying equipment has a complex structure, many power devices, high energy consumption, low utilization rate, and poor drying quality. It is particularly difficult to apply to the drying of some macromolecular materials, and there is also a lack of some simple and efficient drying methods, which seriously affects the development of drying equipment and material properties. Summary of the Invention

[0003] In order to solve one of the above problems, the present application provides a petrochemical environmental protection drying equipment, which includes a drying bin, a control mechanism, a matching mechanism, and a balance positioning bracket. The control mechanism is arranged on the left side of one end of the drying bin, the matching mechanism is arranged on the right side of one end of the drying bin, and the balance positioning bracket is arranged at the bottom of the drying bin to enable the drying equipment to be applicable to the drying of different materials.

[0004] Preferably, it further includes a protective agent pool, which is arranged at the other end of the drying bin. The protective agent pool is provided with a concave opening so that the bottom of the other end of the drying bin can entirely enter the protective agent pool.

[0005] Preferably, the drying bin is columnar. The bottom of the other end of the drying bin is provided with a protective agent inlet hole, the upper part of the other end of the drying bin is provided with a feed inlet, the feed inlet extends in the drying agent bin to the upper end of the protective agent inlet hole, the lower part of one end of the drying bin is provided with a discharge outlet, the feed inlet and the discharge outlet are arranged in parallel, guide plates are arranged around the inside of the drying bin, an air inlet window is arranged on the end face of one end of the drying bin to complete programmed drying in cooperation with the movement, a power supply access area is arranged on the outer surface area of the jacket layer at one end of the drying bin, and a groove is arranged outside the drying bin to cooperate with the balance positioning bracket to control positioning and balance.

[0006] Preferably, the balance positioning bracket includes a positioning seat and a balance shaft. The arc-shaped two ends of the balance shaft are fixed on the positioning seat, the diameter of the balance shaft does not exceed the caliber of the notch of the groove, and the top end of the balance shaft is installed in the groove to enable the drying bin to swing up and down.

[0007] Preferably, the control mechanism includes a lifting base, a positioning rod, an upper push rod, a live wire threading column, and a driven lower pressing rod. The positioning rod is provided with a lifting base, an upper push rod, a live wire threading column, and a driven lower pressing rod in sequence from bottom to top. The upper push rod and the driven lower pressing rod are installed in parallel, and the live wire threading column is vertically installed on the positioning rod. The distance between the upper push rod and the driven lower pressing rod shall not exceed 1.3 times the outer diameter of the drying chamber.

[0008] Preferably, the matching mechanism includes a hole seat, a tension spring, a telescopic column, an up-and-down moving rod, a lower pressing driving rod, a neutral wire threading column, a transmission box, a driving wheel, and a motor. The lower end of the up-and-down moving rod is fixedly connected to one end of the telescopic column and the tension spring. The other end of the telescopic column is inserted into the hole seat and can move up and down, restricting the telescopic column and the connected up-and-down moving rod from moving in the horizontal direction or restricting their movement in other directions. The other end of the tension spring is fixedly connected to the hole seat to pull the up-and-down moving rod downward. The middle section of the up-and-down moving rod is provided with a lower pressing driving rod and a neutral wire threading column from bottom to top. The upper end of the up-and-down moving rod is provided with a transmission box. The driving wheel and the motor are symmetrically arranged at both ends of the transmission box. The lower pressing driving rod and the transmission box are installed in parallel on the same vertical plane. When the driving wheel descends with the up-and-down moving rod, it can closely contact the drying chamber to drive the drying chamber to rotate. The neutral wire threading column is matched with the neutral wire area.

[0009] Preferably, directly below the end of the drying chamber where the lower pressing driving rod of the matching mechanism extends, the upper push rod of the control mechanism is arranged below the lower pressing driving rod. The positioning rod of the control mechanism contacts or is tangent to the drying chamber. The driven lower pressing rod of the control mechanism is arranged above one end of the drying chamber. The driven lower pressing rod, the lower pressing driving rod, and the upper push rod are arranged in alignment in the up-and-down direction.

[0010] Preferably, the initial state includes: one end of the drying chamber is inclined at a low position and the other end is raised at a high position. The lifting base contracts to the lowest position. The lifting base contracts and pulls down the positioning rod and the driven lower pressing rod. The driven lower pressing rod pulls down one end of the drying chamber, and the other end of the drying chamber rises. The tension spring is in a natural contraction state. The driving wheel and the drying chamber are in close contact and can drive the drying chamber to rotate. When adding the immersion protective agent, start the lifting seat to rise. The upper push rod drives the lower pressing driving rod to rise. The lower pressing driving rod drives one end of the drying chamber to rise. The other end of the drying chamber descends, causing the hole of the protective agent to face downward and enter the protective agent pool. The lower pressing driving rod stretches the tension spring through the up-and-down moving rod to make it longer. The up-and-down moving rod drives the driving wheel to rise, causing the driving wheel to have a distance from the drying chamber and disengage from contact, and add materials from the feed port.

[0011] Preferably, when the device starts drying, after the lifting seat is closed, the lifting seat loses the power to rise, and the stretched tension spring returns to its original state to generate a restoring force that drives the downward pressure on the active rod to press down the upper push rod, and the upper push rod drives the positioning rod and the driven downward pressure rod to descend. The driven downward pressure rod presses down one end of the drying chamber to descend, and the other end of the drying chamber rises around the balance shaft. At the same time, the downward pressure on the active rod drives the driving wheel to come into contact with the drying chamber and drive the drying chamber to rotate, heating the drying chamber, and the air guiding window draws air outwards to collect materials or evenly raises the temperature inside the drying chamber. When approaching the drying state, the stretched tension spring returns to its original state to generate a restoring force that drives the downward pressure on the active rod to descend, quickly returning the drying device to its initial state. When one end of the drying chamber descends and tilts, and the air guiding window blows air from the outside into the chamber to reduce the temperature at the outlet end of the chamber to protect the materials from high-temperature damage, the discharge port is opened to quickly unload the materials to prevent high-temperature deformation.

[0012] This application also provides a method or drying program for drying materials using a petrochemical environmental protection drying device. First, ensure that the driving wheel drives the drying chamber to rotate until the protective agent inlet hole faces downwards and is directly opposite the protective agent pool, and at the same time, the feed inlet faces upwards. Start the lifting seat to rise. The other end of the drying chamber descends, causing the protective agent inlet hole to face downwards and enter the protective agent pool. The driving wheel and the drying chamber are spaced apart and out of contact. Select the materials, add no more than half of the drying chamber, and close the feed inlet.

[0013] Secondly, after closing the lifting seat, the driven downward pressure rod presses down one end of the drying chamber to descend, and the other end of the drying chamber rises around the balance shaft. At the same time, the downward pressure on the active rod drives the driving wheel to come into contact with the drying chamber and drive the drying chamber to rotate. When the two ends of the drying chamber reach the balance state and the materials are not all dried, the drying chamber swings up and down repeatedly. When swinging up and down, the lowest position of one end of the drying chamber is not higher than the height of the balance position to reduce stacking pressure, prevent particle surface adhesion reaction, or improve the drying quality. After testing the moisture content of the materials, return the drying device to its initial state, and make the air guiding window blow air from the outside into the chamber to reduce the temperature at the outlet end of the chamber to protect the materials from high-temperature damage, and open the discharge port to quickly unload the materials.

[0014] The beneficial effects of the present invention:

[0015] The drying equipment of the present application has at least one of the following beneficial effects: the drying of materials is achieved through the cooperation of the drying bin 1, the control mechanism 2, the matching mechanism 3, and the balance positioning bracket 4. The structural design is simple and efficient. The driving power devices of the drying bin and the related mechanisms are few but powerful. The energy consumption required to control the up and down movement and rotation of the drying bin is low. The drying equipment can dry according to the required procedures, with a high utilization rate of the motion state. The drying bin is basically closed, and the emissions are easy to control, which is energy-saving, environmentally friendly, simple to operate, fast and efficient in drying, and can control the high-temperature stage of the materials to further protect the materials and prevent material property changes, especially suitable for the drying of macromolecular materials or materials, with obvious environmental protection effects.

[0016] The method for drying materials of the present invention has at least one of the following beneficial effects: the method or drying procedure of the present invention is simple and easy to promote. The method of the present invention is especially suitable for the drying of macromolecular materials or materials, preventing the surface of polymer particles from undergoing property changes during drying when the water content is low or at high temperatures for a long time. The energy consumption is low, the utilization rate of the motion state is high, the drying bin is basically closed, and the emissions are easy to control, which is energy-saving, environmentally friendly, and has relatively important significance in the field of promoting environmental protection through energy conservation.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] As Figure 1 shown, a petrochemical environmental protection drying device includes a drying bin 1, a control mechanism 2, a matching mechanism 3, a balance positioning bracket 4, and also includes a protective agent pool 5, and the protective agent pool 5 is arranged at the other end of the drying bin. The control mechanism is arranged on the left side of one end of the drying bin, the matching mechanism is arranged on the right side of one end of the drying bin, and the balance positioning bracket is arranged at the bottom of the drying bin so that the drying device is applicable to drying different materials; the protective agent pool 5 is provided with a concave opening so that the entire bottom of the other end of the drying bin 1 can enter the protective agent pool 5.

[0028] As Figure 2 shown, the drying bin 1 is columnar, and a protective agent inlet hole 11 is arranged at the bottom of the other end of the drying bin 1. Preferably, the aperture of the inlet hole is not greater than 8 mm. An inlet port 12 is arranged at the upper part of the other end of the drying bin 1, and the inlet port extends into the drying agent bin to the upper end of the protective agent inlet hole to facilitate the accurate contact between the protective agent and the materials in the inlet port. An outlet port 16 is arranged at the lower part of one end of the drying bin, and the outlet port 16 is preferably arranged on an inclined surface for discharging materials. The inlet port 12 and the outlet port 16 are arranged in parallel. A flow guide plate 19 is arranged around the inner part of the drying bin, preferably 8. The flow guide plate 19 is bent and arranged between the inlet port and the outlet port inside the drying bin to facilitate uniform drying or delay the accumulation of materials when the drying bin 1 descends at one end. An air induction window 15 is arranged on the end surface of one end to cooperate with the movement to complete programmed drying. Preferably, the air induction window 15 draws air outwards to collect materials or uniformly heats up the inside of the drying bin 1 from the balanced position to the descent of one end, and when the drying bin 1 descends from the balanced position to one end, the air induction window 15 sends air into the bin from the outside to reduce the temperature at the outlet end of the bin to protect the materials from high-temperature damage. Preferably, an electric control device such as an electric control fan is arranged on the air induction window 15. The drying bin 1 is arranged as a double-layer structure. Preferably, the outer layer is a jacket layer 18 to heat the inside of the drying bin 1. Preferably, an electric heater and a heat-conducting liquid are arranged in the jacket layer 18. A power supply access area is arranged on the outer surface area of the jacket layer 18 at one end of the drying bin 1. The preferred scheme is a live wire area 14 and a neutral wire area 17 in sequence. The power supply access area can supply power to the electrical appliances on the drying bin 1, and in the case of power failure, heat supply can also be directly supplemented by heating with a heat source outside the jacket. A groove 13 is arranged outside the drying bin 1 to cooperate with the balance positioning bracket 4 to control positioning and balance. Preferably, the groove 13 is arranged on one side close to the protective agent inlet hole 11.

[0029] As Figure 3As shown, the balance positioning bracket 4 includes a positioning seat 41 and a balance shaft 42. The balance shaft 42 is arc-shaped, preferably quasi-arc-shaped. The two arc-shaped ends of the balance shaft 42 are fixed on the positioning seat 41. The diameter of the balance shaft 42 does not exceed the caliber of the notch of the groove 13. The top end of the balance shaft 42 is installed in the groove 13 to enable the drying bin 1 to swing up and down. Further, the groove of the drying bin 1 swings up and down around the arc top of the balance shaft. The positioning seat 41 can be fixed at an adjustable height or fixed by landfill. Further, in order to prevent the drying bin from sliding to any one of the two arc ends, two vertical railings 43 can be arranged on both sides of the drying bin near the groove. The gap between the vertical railings 43 and the surface of the drying bin is 1-3 mm to facilitate the movement of the drying bin. The two vertical railings 43 are fixed on the positioning seat 41, and the diameters of the two vertical railings 43 are larger than the caliber of the groove.

[0030] As Figure 4 As shown, the control mechanism 2 includes a lifting base 21, a positioning rod 23, an upper push rod 22, a live wire threading post 25, and a driven lower pressure rod 24. The lifting base 21, the upper push rod 22, the live wire threading post 25, and the driven lower pressure rod 24 are arranged on the positioning rod 23 from bottom to top in sequence. The upper push rod 22 and the driven lower pressure rod 24 are installed in parallel, preferably on the same vertical plane. The live wire threading post 25 is vertically installed on the positioning rod 23, preferably the installation position of the live wire threading post 25 is tangent to the direction of the outer surface of the drying bin 1. The distance between the upper push rod 22 and the driven lower pressure rod 24 shall not exceed 1.3 times, preferably 1.1 times, the outer diameter of the drying bin 1. A wear-resistant conductive rod 251 is arranged on the live wire threading post 25 to cooperate with the live wire area 14. A block 221 is arranged on the upper push rod 22 to prevent the horizontal movement of the lower pressure active rod 32. The lifting base 21 can be fixed. Preferably, the wear-resistant conductive rod 251 is provided with an elastic contraction material to cooperate with the movement of the live wire area when the positioning rod 23 moves up and down.

[0031] As Figure 5As shown, the matching mechanism 3 includes a hole seat 30, a tension spring 31, a telescopic column 35, an up-and-down movement rod 34, a downward pressure active rod 32, a zero-line threading column 38, a transmission box 37, a driving wheel 33, and a motor 36. The lower end of the up-and-down movement rod 34 is fixedly connected to one end of the telescopic column 35 and the tension spring 31. The other end of the telescopic column 35 is inserted into the hole seat 30 and can move up and down, restricting the telescopic column and the connected up-and-down movement rod 34 from moving in the horizontal direction or restricting movement in other directions. The other end of the tension spring 31 is fixedly connected to the hole seat 30 to pull the up-and-down movement rod 34 downward. In the middle section of the up-and-down movement rod 34, a downward pressure active rod 32 and a zero-line threading column 38 are arranged from bottom to top. The upper end of the up-and-down movement rod 34 is provided with a transmission box 37. At both ends of the transmission box 37, a driving wheel 33 and a motor 36 are symmetrically arranged. The downward pressure active rod 32 and the transmission box 37 are installed in parallel on the same vertical plane. When the driving wheel 33 descends with the up-and-down movement rod 34, it can closely adhere to the drying bin 1 to drive the drying bin 1 to rotate. The zero-line threading column 38 cooperates with the zero-line area 17. The zero-line threading column and the live-line threading column introduce power from the outside. The hole seat 30 can be fixed. Preferably, the zero-line threading column is provided with an elastic contraction material so that when the up-and-down movement rod 34 moves up and down, it can cooperate with the movement of the zero-line area.

[0032] As Figure 5-7 shown, the downward pressure active rod 32 of the matching mechanism 3 extends into the drying bin directly below one end. The upper push rod 22 of the control mechanism 2 is arranged below the downward pressure active rod 32. Preferably, the lower surface of the downward pressure active rod 32 is closely attached to the upper surface of the upper push rod 22. One side of the up-and-down movement rod 34 of the matching mechanism 3 is in contact with or tangent to the drying bin 1. The positioning rod 23 of the control mechanism 2 is in contact with or tangent to the drying bin 1. Preferably, a rolling device such as the contact points of the driven downward pressure rod 24, 26, 321, 341 is arranged in the contact area of the control mechanism 2, the matching mechanism 3, and the drying bin 1. Among them, 26, 321, 341 are shown in Figures 5 to 6 , the driven downward pressure rod 24 of the control mechanism 2 is arranged above one end of the drying bin. The driven downward pressure rod 24, the downward pressure active rod 32, and the upper push rod 22 are arranged in alignment in the up-and-down direction. The downward pressure active rod 32 is arranged in the block 221. A wear-resistant conductive rod 251 is arranged on the live-line threading column 25 to make a moving contact with the live-line area 14. The zero-line threading column 38 makes a moving contact with the zero-line area 17.

[0033] The working principle and related structural relationships of a petrochemical environmental protection drying equipment are described below. The initial state or the state after installation is as follows: As Figure 7 shown, one end of the drying bin is inclined and at a low position, and the other end is rising and at a high position. As Figure 7As shown in the enlarged view b, the lifting base 21 contracts to the lowest position. The contraction of the lifting base 21 pulls down the positioning rod 23 and the driven pressing rod 24 downward. The driven pressing rod 24 pulls one end of the drying bin to descend, and the other end of the drying bin ascends. The tension spring 31 is in a natural contraction state. As Figure 7 As shown in the enlarged view a, the pitch of the tension spring 31 is smaller in the natural contraction state. The driving wheel 33 is in close contact with the drying bin 1 and can drive the drying bin 1 to rotate. Preferably, the driving wheel 33 drives the drying bin 1 to rotate until the protective agent inlet hole 11 faces downward and is directly opposite to the protective agent pool 5, and at the same time, the feeding port 12 faces upward. The distance between 24 and 32 is greater than the outer diameter of the drying bin so that one end of the drying bin can shake slightly up and down in the initial state.

[0034] The tension spring 31 is selected such that the restoring force generated when it returns to its original state after being stretched can slowly lift the other end of the above-mentioned drying bin (when the drying bin is filled with dried materials with a volume of one-half of the drying bin). The tax rate of the dried materials is not less than 65%, and the density of the dried materials is 0.9 - 1.2 g / cm 3 , and the dried materials in the drying bin are pulled up relatively quickly by the tension spring 31 as the weight of the dried materials decreases due to water loss during drying in the drying bin. When one end of the drying bin passes the balance position, it falls faster. If one end of the drying bin descends rapidly and generates a force impact on the smaller pitch of the tension spring 31 in the natural contraction state, the smaller pitch of the tension spring 31 rebounds slightly to vibrate the drying bin to prevent the materials from being damaged by long-term contact with high temperature. Further, the slight rebound is beneficial to the rapid discharging of the discharge port.

[0035] When adding the protective agent to immerse the equipment, it is necessary to start the lifting seat 21 to rise. The upper push rod 22 drives the lower pressing main rod 32 to rise. The lower pressing main rod 32 drives one end of the drying bin to rise, and the other end of the drying bin descends, causing the protective agent inlet hole 11 to face downward and enter the protective agent pool 5. As Figure 8 shown, the lower pressing main rod 32 stretches the tension spring 31 to elongate through the up-and-down movement rod 34. The pitch of the tension spring 31 is significantly increased compared to the natural contraction state. At the same time, as Figure 8 shown in the enlarged view A, the up-and-down movement rod 34 drives the driving wheel 33 to rise, causing the driving wheel 33 to be separated from the drying bin and have a distance therebetween. Further, the distance does not exceed 3 cm, further preventing the driving wheel 33 from driving the drying bin to rotate and causing the failure of the protective agent to immerse the drying bin. Chemical materials are added from the feeding port 12.

[0036] When the device starts drying after adding materials, after closing the lifting seat 21, the lifting seat 21 loses the power to rise and can also return to the lowest position. Preferably, the partial top head at the upper end of the lifting seat 21 can move up and down freely after the lifting seat 21 loses power to facilitate better cooperation with the mechanism 3. Preferably, the lifting base 21 is a hydraulic lift or a hydraulic jack. The stretched tension spring 31 returns to its original state and generates a restoring force to drive the downward pressure active rod 32. The downward pressure active rod 32 presses down the upper push rod 22 to descend. The upper push rod 22 drives the positioning rod 23 and the driven downward pressure rod 24 to descend. As Figure 9 shown in the enlarged view d, the driven downward pressure rod 24 comes into close contact with the drying chamber to exert force. The driven downward pressure rod 24 presses down one end of the drying chamber to descend, and the other end of the drying chamber rises around the balance shaft. At the same time, the downward pressure active rod 32 drives the driving wheel 33 to come into contact with the drying chamber and drives the drying chamber to rotate, heating the drying chamber. The air guiding window 15 guides air outwards to collect materials or enables the temperature inside the drying chamber 1 to rise uniformly, as Figure 9 , when the two ends of the drying chamber reach the equilibrium state, as Figure 9 shown in the enlarged view c, the pitch of the stretched tension spring 31 decreases but it does not return to the natural contraction state, and the rising distance of the lifting seat 21 decreases. When the materials are approaching drying, when one end of the drying chamber descends and tilts, and the air guiding window 15 sends air from the outside into the chamber to reduce the temperature at the outlet end inside the chamber to protect the materials from high-temperature damage, the discharge port 16 is opened to quickly discharge the materials to prevent high-temperature deformation. Preferably, when the materials dry slowly, before one end of the drying chamber descends and tilts, the lifting seat 21 can be instantaneously started to rise instantaneously and then stopped. The drying chamber swings up and down and rotates near the equilibrium position height (the height of the drying chamber when the two ends of the drying chamber reach the equilibrium state around or with the arc top of the balance shaft as the fulcrum), preferably the lowest position of one end when swinging up and down is not higher than the equilibrium position height, reducing stacking pressure to prevent particle surface adhesion reaction and collecting more materials better. When approaching the drying state, the lifting seat is no longer instantaneously started. The stretched tension spring 31 returns to its original state and generates a restoring force to drive the downward pressure active rod 32 to descend quickly to realize the drying equipment returning to the Figure 7 initial state as shown. Collection facilities can be set at the air windows and holes of the equipment to collect and control the discharged water vapor. The drying chamber is basically closed and the discharge is easy to control.

[0037] The drying equipment of the present application realizes the drying of materials under the cooperation of the drying bin 1, the control mechanism 2, the matching mechanism 3, and the balance positioning bracket 4. The structure design is simple and the operation is efficient. The driving power devices of the drying bin and the related mechanisms are few but powerful. The energy consumption required to control the up and down movement and rotation of the drying bin is low. The drying equipment can be dried according to the required program, and the utilization rate of the motion state is high. The drying bin is basically closed and the discharge is easy to control, which is energy-saving and environmentally friendly. The device is easy to operate, dries quickly and efficiently, controls the high-temperature stage of the material, and further protects the material from physical changes. It is especially suitable for the drying of macromolecular materials or materials, and the environmental protection effect is obvious.

[0038] The following describes a method or drying procedure for drying materials using a petrochemical environmental protection drying equipment. The material is selected as polymer hydrocolloid particles with a molecular weight of more than 1 million, preferably polyvinyl alcohol hydrocolloid particles, potassium polyvinyl alcohol hydrocolloid particles, and polyamide sol particles. In order to prevent the surface of the polymer particles from undergoing physical changes when the water content is low or at high temperature for a long time, the particles need to be quickly dried after being soaked in a protective agent solution on the surface. Select a petrochemical environmental protection drying equipment to dry. First, ensure that the driving wheel 33 drives the drying bin 1 to rotate until the protective agent inlet hole 11 faces downwards and is directly opposite to the protective agent pool 5, and at the same time the feed inlet 12 faces upwards. Start the lifting seat 21 to rise, and the other end of the drying bin drops, causing the protective agent inlet hole 11 to face downwards and enter the protective agent pool 5. The driving wheel 33 is separated from the drying bin to produce a spacing. Select materials with a particle size not less than the diameter of the inlet hole, add no more than half of the drying bin, and the volume of the polymer material expands slightly after soaking to further prevent the material from flowing out of the inlet hole. Close the feed inlet.

[0039] Secondly, after closing the lifting seat 21, the stretched spring 31 returns to its original state and generates a restoring force to drive the downward pressure of the active rod 32 to press down the upper push rod 22 to descend. The driven downward pressure rod 24 presses down one end of the drying bin to descend, and the other end of the drying bin rises around the balance shaft. At the same time, the downward pressure active rod 32 drives the driving wheel 33 to contact the drying bin and drive the drying bin to rotate. Heat the drying bin, manually or electrically ventilate the air window 15 to draw air outwards to collect the preliminarily dried materials and move them towards the discharge port or make the temperature in the drying bin 1 rise evenly. When the two ends of the drying bin reach a balanced state, test the moisture content of the materials. When it is close to the drying state and does not exceed 15%, return the drying equipment to the initial state for discharging. Further, make one end of the drying bin swing up and down and rotate repeatedly at the balance position or not higher than the balance position height to reduce the stacking pressure to prevent particle surface adhesion reaction or improve the drying quality. In order to better prevent the material from leaking due to long-term accumulation into the inlet hole, test the moisture content of the materials. When it is close to the drying state and does not exceed 15%, return the drying equipment to the initial state, make the air window 15 send air from the outside to the inside of the bin to reduce the temperature at the outlet end of the bin to protect the material from high-temperature damage, and open the discharge port 16 to quickly discharge the material to further prevent the physical change of the high-temperature material.

[0040] The method or process for drying materials of the present invention is simple and easy to promote. The method of the present invention is particularly suitable for drying macromolecular materials or substances, preventing surface deformation of polymer particles during drying when the water content is low or at high temperature for a long time. It requires low energy consumption, has a high utilization rate of the motion state, the drying bin is basically closed and the emissions are easy to control, and it is energy-saving and environmentally friendly. The present invention has relatively important significance in the field of promoting environmental protection through energy conservation.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.

The neutral wire threading column cooperates with the neutral wire area.

7. Any one of the petrochemical environmental protection drying equipment according to claims 1-6, characterized in that, The downward pressing active rod of the matching mechanism extends below one end of the drying bin that extends into the drying bin. The upper push rod of the control mechanism is arranged below the downward pressing active rod. The positioning rod of the control mechanism contacts or is tangent to the drying bin. The driven downward pressing rod of the control mechanism is arranged above one end of the drying bin. The driven downward pressing rod, the downward pressing active rod, and the upper push rod are arranged in alignment in the up and down direction.

8. Any of the petrochemical environmental protection drying equipment according to claims 1-6, characterized in that, The initial state includes: one end of the drying bin is inclined at a low position and the other end rises to a high position. The lifting base contracts to the lowest position. The lifting base contracts and pulls down the positioning rod and the driven downward pressing rod. The driven downward pressing rod pulls down one end of the drying bin, and the other end of the drying bin rises. The tension spring is in a natural contraction state. The driving wheel and the drying bin are in close contact and can drive the drying bin to rotate. When adding immersion protectant, start the lifting seat to rise. The upper push rod drives the downward pressing active rod to rise. The downward pressing active rod drives one end of the drying bin to rise. The other end of the drying bin drops, causing the protectant inlet hole to face downward into the protectant pool. The downward pressing active rod stretches the tension spring to elongate through the up and down movement rod. The up and down movement rod drives the driving wheel to rise, causing the driving wheel to be spaced apart from and out of contact with the drying bin, and adding materials from the feed inlet.

9. Any of the petrochemical environmental protection drying equipment according to claims 1-6, characterized in that, When the equipment starts drying, after closing the lifting seat, the lifting seat loses the power to rise. The stretched tension spring returns to its original state and generates a restoring force to drive the downward pressing active rod to press down and the upper push rod to drop. The upper push rod drives the positioning rod and the driven downward pressing rod to drop. The driven downward pressing rod presses down one end of the drying bin to drop, and the other end of the drying bin rises around the balance axis. At the same time, the downward pressing active rod drives the driving wheel to contact the drying bin and drive the drying bin to rotate, heating the drying bin, and the air guiding window guides air outwards to collect materials or evenly heat the inside of the drying bin. When approaching the drying state, let the stretched tension spring return to its original state and generate a restoring force to drive the downward pressing active rod to drop quickly to return the drying equipment to the initial state. When one end of the drying bin drops and inclines, and the air guiding window blows air from the outside into the bin to reduce the temperature at the outlet end of the bin to protect the materials from high temperature damage, open the discharge port to quickly unload the materials to prevent high temperature deformation.

10. A method or drying process for drying materials using a petrochemical environmental protection drying device, characterized in that, First, ensure that the driving wheel drives the drying bin to rotate until the protectant inlet hole faces downward and is directly opposite to the protectant pool. At the same time, the feed inlet faces upward. Start the lifting seat to rise. The other end of the drying bin drops, causing the protectant inlet hole to face downward into the protectant pool. The driving wheel is spaced apart from and out of contact with the drying bin. Select materials and add no more than half of the drying bin, and then close the feed inlet. Secondly, after closing the lifting seat, the driven downward pressing rod presses down one end of the drying bin to descend, and the other end of the drying bin rises around the balance shaft for heating and drying. At the same time, the downward pressing driving rod drives the driving wheel to contact the drying bin and drive the drying bin to rotate. After the two ends of the drying bin reach the balance state and the moisture of the tested material is dried, during the process of the drying equipment returning to the initial state, the air guiding window blows air from the outside into the bin to reduce the temperature at the outlet end inside the bin to protect the material from high-temperature damage, and the discharge port is opened to quickly discharge the material.
