[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention drives the connecting shaft to rotate through the driving disk, and the connecting shaft drives the deflection plate at the bottom to rotate. The deflection plate can drive the introduction nozzle and the conducting tube to rotate, so that the introduction nozzle moves to the bottom of one of the through holes. During this process, the introduction nozzle will contact the bottom of the pressure ring. Since the bottom edge of the pressure ring is designed with a slope, the introduction nozzle will push the pressure ring to move up and squeeze multiple supporting springs. When the opening of the introduction nozzle is located at the center of the pressure ring, the deflection plate will no longer move, and the pressure ring is squeezed by the elastic force of the supporting spring so that the pressure ring can fit tightly with the introduction nozzle. Secondly, the slag discharge valve outside the discharge pipe is opened. Due to the pressure difference between the air pressure in the C4 liquefied gas processing box and the external atmospheric pressure, the purified and filtered C4 liquefied gas flows in reverse to remove impurities trapped in the filter holes and the inner wall of the filter element. The impurities are backwashed into the introduction nozzle and then discharged from the discharge pipe through the introduction nozzle, the conducting tube and the rotary joint. In the entire clearing process, The process is carried out inside the liquefied gas treatment box, and the discharge pipe guides the impurities into the external collection container for centralized treatment, thereby improving the environmental friendliness of the actual application of the device. After the unblocking work of a single purification filter component is completed, the turntable rotates inside the arc groove, so that the drive disk is in a stationary state, and the drive disk, connecting shaft and the deflection plate below do not rotate, thereby limiting the inlet nozzle and preventing the inlet nozzle from deviating from the through hole and affecting the discharge of impurities. As the turntable continues to rotate and drives the baffle column to slide into the concave hole, the baffle column pushes the drive disk to rotate sixty degrees again. Similarly, the deflection plate below drives the inlet nozzle to rotate sixty degrees and is located directly below the next through hole. In this way, after the inlet nozzle rotates one circle, the purpose of automatic backflushing and unblocking of all purification filter components in the C4 liquefied gas treatment box is achieved. There is no need to stop the machine to unblock the purification filter components, which makes the operation cycle of the device long and the maintenance cost low, ensuring the continuous processing of C4 liquefied gas.
[0013] 2. The present invention removes the purification filter assembly from the C4 liquefied gas processing box by holding the handle and rotating it, so that the fixing ring drives the two limit plugs to rotate inside the slot, and when the limit plug rotates to the opening at the bottom of the groove, the handle is lifted, so that the handle drives the purification filter assembly upward through the column, so that the purification filter assembly moves upward in the installation hole until the purification filter assembly is completely separated from the C4 liquefied gas processing box, so that the purification filter assembly can be removed for daily maintenance. When installing the purification filter assembly, the bottom end of the purification filter assembly is passed through the installation hole, so that the bottom end of the filter cartridge in the purification filter assembly is inserted between the clamping ring and the guide tube, and the filter assembly is installed. The guide tube with a conical design at the top serves to limit and guide the filter cartridge so that the opening at the bottom of the filter cartridge and the through hole are on the same vertical line. Secondly, the fixing ring is pressed down by the handle so that the two limiting plugs are inserted into the slot through the groove. Similarly, the fixing ring squeezes the sealing gasket below, causing the sealing gasket to deform and fit tightly with the inner wall of the mounting hole, thereby improving the sealing performance of the purification filter assembly installation. The fixing ring is then rotated by the handle so that the fixing ring drives the two limiting plugs to rotate inside the slot, causing the limiting plugs to be misaligned with the groove, so that the limiting assembly and the purification filter assembly no longer move upward, thereby improving the stability of the purification filter assembly installation.

When the opening of the inlet nozzle 142 is located at the center of the pressure ring 803, the deflection plate 141 will no longer move, and the pressure ring 803 will be squeezed by the elastic force of the support spring 804, so that the pressure ring 803 can fit tightly with the inlet nozzle 142, thereby isolating the liquefied gas inside and outside the through hole 6.
[0021] As a further embodiment of the present invention, the purification filter assembly 9 includes a filter cartridge 901.

During operation, the filter element 903 in the purification and filtering assembly 9 purifies and filters the C4 liquefied gas, so that impurities will adhere to the inside of the filter element 903. After passing through the filter element 903, the C4 liquefied gas passes through the filter hole 902 outside the filter cylinder 901, so that the filter hole 902 again filters the impurities in the C4 liquefied gas.
[0022] As a further embodiment of the present invention, the limiting assembly 10 includes a column 101, the bottom end of the column 101 is fixed to the top of the filter cartridge 901, the column 101 is inserted into the mounting hole 15, a fixing ring 102 is fixed to the outer wall of the column 101, a handle 104 is fixed to the fixing ring 102, and limiting plugs 103 are fixed on both sides of the fixing ring 102, respectively. The two limiting plugs 103 are inserted into the slots 16 on the inner wall of the mounting hole 15; During operation, when the limiting plug 103 rotates to the opening at the bottom of the groove 17, the handle 104 is lifted, so that the handle 104 drives the purification filter assembly 9 to move upward through the column 101, so that the purification filter assembly 9 moves upward in the installation hole 15 until the purification filter assembly 9 is completely separated from the C4 liquefied gas processing box 1, so that the purification filter assembly 9 can be removed for daily maintenance; During operation, the fixing ring 102 is rotated by the handle 104, so that the fixing ring 102 drives the two limiting plugs 103 to rotate inside the slot 16, so that the limiting plugs 103 are misaligned with the groove 17, so that the limiting component 10 and the purification filter component 9 no longer move upward.
[0023] As a further solution of the present invention, a sealing gasket 105 is sleeved on the outside of the column 101, the top of the sealing gasket 105 overlaps the bottom of the fixing ring 102, and the sealing gasket 105 is clamped in the mounting hole 15 and the bottom overlaps the boss in the mounting hole 15; During operation, the fixing ring 102 is pressed down by the handle 104 so that the two limiting plugs 103 are inserted into the slot 16 through the groove 17. Similarly, the fixing ring 102 squeezes the sealing gasket 105 below, causing the sealing gasket 105 to deform and fit tightly with the inner wall of the mounting hole 15, thereby improving the sealing performance of the purification filter assembly 9.

The angle between two adjacent concave holes 123 and two adjacent arc-shaped grooves 122 is sixty degrees, and a turntable 124 is overlapped in one of the arc-shaped grooves 122.

The blocking post 125 pushes the driving disk 121 to rotate through the concave hole 123, and the driving disk 121 drives the connecting shaft 11 to rotate. The connecting shaft 11 drives the deflection plate 141 at the bottom to rotate, and the deflection plate 141 can drive the introduction nozzle 142 and the guide tube 143 to rotate. When the blocking post 125 slides out of the current concave hole 123, the driving disk 121 drives the deflection plate 141 to rotate sixty degrees through the connecting shaft 11, that is, the introduction nozzle 142 on the deflection plate 141 moves to the bottom of one of the through holes 6, thereby facilitating the fixed angle adjustment of the introduction nozzle 142. The turntable 124 rotates inside the arc groove 122, so that the driving disk 121 is in a stationary state, and the driving disk 121, the connecting shaft 11 and the lower deflection plate 141 do not rotate, thereby limiting the introduction nozzle 142 and preventing the introduction nozzle 142 from deviating from the through hole 6 and affecting the discharge of impurities.
[0025] As a further embodiment of the present invention, the slag discharge assembly 14 includes a deflection plate 141, one end of which is fixed to the bottom end of the connecting shaft 11, and an introduction nozzle 142 is fixed above the other end of the deflection plate 141. The bottom of the introduction nozzle 142 passes through the deflection plate 141 and is connected to a conducting pipe 143. The other end of the conducting pipe 143 is connected to a rotary joint 144. Since the bottom end of the conducting pipe 143 is connected to the top end of the discharge pipe 145 via the rotary joint 144, the connection between the discharge pipe 145 and the conducting pipe 143 will not be affected during the rotation of the conducting pipe 143. The bottom of the rotary joint 144 is connected to a discharge pipe 145, and the other end of the discharge pipe 145 passes through the bottom of the C4 liquefied gas processing box 1 and is installed with a slag discharge valve 146; During operation, the slag discharge valve 146 outside the discharge pipe 145 is opened, and the impurities are backwashed into the inlet nozzle 142, and then discharged from the discharge pipe 145 through the inlet nozzle 142, the conducting pipe 143 and the rotary joint 144. In addition, the entire clearing process is carried out inside the C4 liquefied gas processing box 1, and the discharge pipe 145 introduces the impurities into the external collection container for centralized treatment, thereby improving the environmental friendliness of the actual application of the device.
[0026] Working principle of the present invention: When in use, the C4 liquefied gas pipeline to be processed is connected at the air inlet flange pipe 2, and the C4 liquefied gas is introduced into the bottom of the C4 liquefied gas processing box 1 through the booster mechanism on the pipeline. The C4 liquefied gas is isolated by the middle partition 5, so that the C4 liquefied gas can pass through multiple through holes 6 and the guide component 8 to enter the purification filter component 9. The filter element 903 in the purification filter component 9 purifies and filters the C4 liquefied gas, so that impurities will adhere to the inside of the filter element 903. The C4 liquefied gas passes through the filter element 903 and then passes through the filter element 903. The filter holes 902 outside the filter cartridge 901 allow the filter holes 902 to filter the impurities in the C4 liquefied gas again. The treated C4 liquefied gas passes through the filter holes 902 and enters the upper position of the C4 liquefied gas treatment box 1. The C4 liquefied gas is isolated in cooperation with the middle partition plate 5 so that the purified and filtered C4 liquefied gas will not be introduced below the middle partition plate 5. During this process, the discharge valve pipe 3 above the outer wall of the C4 liquefied gas treatment box 1 is in an open state, which can discharge the filtered C4 liquefied gas for subsequent centralized collection. When the filter assembly 9 is unblocked, the motor 126 is controlled to work to drive the turntable 124 to rotate. During the rotation of the turntable 124 driving the blocking column 125, it can slide into the concave hole 123 outside the driving disk 121. The blocking column 125 pushes the driving disk 121 to rotate through the concave hole 123, and the driving disk 121 drives the connecting shaft 11 to rotate. The connecting shaft 11 drives the deflection plate 141 at the bottom to rotate, and the deflection plate 141 can drive the introduction nozzle 142 and the guide pipe 143 to rotate. Since the bottom end of the guide pipe 143 is connected to the top end of the discharge pipe 145 through the rotary joint 144, the connection state between the discharge pipe 145 and the guide pipe 143 will not be affected during the rotation of the guide pipe 143. When the blocking column 125 slides out of the current concave hole 123, the driving disk 1 21 drives the deflection plate 141 to rotate sixty degrees through the connecting shaft 11, that is, the introduction nozzle 142 on the deflection plate 141 moves to the bottom of one of the through holes 6. During this process, the introduction nozzle 142 will contact the bottom of the pressure ring 803. Since the bottom edge of the pressure ring 803 is designed with a bevel, the introduction nozzle 142 will push the pressure ring 803 to move upward and squeeze the multiple support springs 804. When the opening of the introduction nozzle 142 is located at the center of the pressure ring 803, the deflection plate 141 no longer moves. The elastic force of the support springs 804 squeezes the pressure ring 803 so that the pressure ring 803 can fit tightly with the introduction nozzle 142, thereby isolating the liquefied gas inside and outside the through hole 6. At this time, the liquefied gas below the middle partition plate 5 cannot pass through the through hole 6 into the upper filter element 903; Secondly, open the slag discharge valve 146 outside the discharge pipe 145. Due to the pressure difference between the air pressure in the C4 liquefied gas treatment box 1 and the external atmospheric pressure, the purified and filtered C4 liquefied gas flows in reverse to remove impurities trapped on the filter hole 902 and the inner wall of the filter element 903. The impurities are backwashed into the introduction nozzle 142 and then discharged from the discharge pipe 145 through the introduction nozzle 142, the guide pipe 143 and the rotary joint 144. In the entire clearing process, it is carried out inside the C4 liquefied gas treatment box 1. The discharge pipe 145 introduces the impurities into the external collection container for centralized treatment, thereby improving the environmental protection of the actual application of the device. After completing the clearing work of a single purification and filtering component 9, the turntable 124 is in the arc groove 1 22 rotates internally, so that the driving disk 121 is in a stationary state, so that the driving disk 121, the connecting shaft 11 and the lower deflection plate 141 do not rotate, which serves the purpose of limiting the introduction nozzle 142 and preventing the introduction nozzle 142 from deviating from the through hole 6 and affecting the discharge of impurities. As the turntable 124 continues to rotate and drives the blocking column 125 to slide into the concave hole 123, the blocking column 125 pushes the driving disk 121 to rotate sixty degrees again. Similarly, the lower deflection plate 141 drives the introduction nozzle 142 to rotate sixty degrees and is located directly below the next through hole 6. In this way, when the introduction nozzle 142 rotates one circle, the purpose of automatically backflushing and clearing the blockage of all purification and filtering components 9 in the C4 liquefied gas processing box 1 is achieved; When removing the purification filter assembly 9 from the C4 liquefied gas processing box 1, hold the handle 104 and rotate it, so that the fixing ring 102 drives the two limiting plugs 103 to rotate inside the slot 16. When the limiting plug 103 rotates to the opening at the bottom of the groove 17, lift the handle 104, so that the handle 104 drives the purification filter assembly 9 to move upward through the column 101, so that the purification filter assembly 9 moves upward in the installation hole 15 until the purification filter assembly 9 is completely separated from the C4 liquefied gas processing box 1, so that the purification filter assembly 9 can be removed for daily maintenance. When installing the purification filter assembly 9, the bottom end of the purification filter assembly 9 is passed through the installation hole 15, so that the bottom end of the filter cartridge 901 in the purification filter assembly 9 is inserted between the clamping ring 801 and the guide tube 802. Cooperating with the guide tube 802 with a conical top design, it plays the role of limiting and guiding the filter cartridge 901, so that the opening at the bottom of the filter cartridge 901 is on the same vertical line as the through hole 6. Secondly, the fixing ring 102 is pressed down by the handle 104 so that the two limiting plugs 103 are stuck in the slot 16 through the groove 17. Similarly, the fixing ring 102 squeezes the sealing gasket 105 below, so that the sealing gasket 105 is deformed and fits tightly with the inner wall of the mounting hole 15, thereby improving the sealing performance of the installation of the purification filter assembly 9. Then, the fixing ring 102 is rotated by the handle 104, so that the fixing ring 102 drives the two limiting plugs 103 to rotate inside the slot 16, so that the limiting plug 103 is misaligned with the groove 17, so that the limiting assembly 10 and the purification filter assembly 9 no longer move up.
