Description

Technical Field

[0001] This invention relates to the field of air separation equipment technology, specifically to a wastewater discharge device for air separation equipment. Background Technology

[0002] Air separation equipment is used to gradually separate inert gases such as oxygen, nitrogen, and argon from liquid air. Air separation equipment uses air as raw material, turns air into liquid through compression and deep freezing, and then gradually separates inert gases such as oxygen, nitrogen, and argon from the liquid air through distillation.

[0003] After prolonged operation, existing air separation equipment accumulates a large amount of dirt at its bottom, which needs to be cleaned regularly. Existing sewage discharge equipment has a sewage discharge valve at the bottom. When the valve is opened, the dirt falls off the air separation equipment due to its own gravity. At this time, a large amount of dirt will splash around. When the dirt is left to stand for a long time, it will cause the valve to become blocked, requiring manual removal. Summary of the Invention

[0006] The sewage discharge assembly includes a sewage discharge mechanism, and an adjustment mechanism is installed on the outer wall of the sewage discharge mechanism;

[0007] The sewage discharge mechanism includes a horizontal sewage discharge pipe, a piston pusher cylinder is slidably connected to the inner wall of the horizontal sewage discharge pipe, a pusher screw is threadedly connected to the inner wall of the piston pusher cylinder, the pusher screw is fixedly sleeved on the power output shaft of the pusher motor, the pusher motor is fixedly mounted on the horizontal sewage discharge pipe, and a connecting rod is fixedly mounted on the outer wall of the piston pusher cylinder.

[0008] The adjustment mechanism includes an adjustment block, which is slidably connected to a connecting rod. A switch rod is slidably connected to the outer wall of the adjustment block. A square groove is formed on the outer wall of the switch rod, and a toothed groove is formed on the top of the switch rod.

[0009] The outer wall of the horizontal sewage pipe is fixedly fitted with a fixed bracket, and the outer wall of the fixed bracket is provided with a fixed groove. The adjusting block is slidably connected to the fixed groove.

[0010] A fixed block is fixedly mounted on the outer wall of the adjusting block, and a movable screw is fixedly mounted on the inner wall of the fixed block. An adjusting worm gear is threadedly connected to the outer edge of the movable screw, and the adjusting worm gear is movably connected to the switch rod.

[0011] The adjusting worm gear is threadedly connected to the outer edge of the adjusting worm wheel, and an adjusting handle is fixedly mounted on the outer edge of the adjusting worm gear. The adjusting worm gear is movably connected to the switch rod.

[0012] The outer wall of the horizontal sewage pipe is provided with a horizontal groove, and the connecting rod is slidably connected to the horizontal groove.

[0013] The end of the transverse sewage pipe away from the drive motor is provided with a pipe cover. The pipe cover is installed on the transverse sewage pipe through a connecting shaft, and the connecting shaft is movably connected to the transverse sewage pipe.

[0014] Both ends of the connecting shaft are equipped with gears, which mesh with tooth grooves.

[0015] As a preferred embodiment of the present invention, the inner wall of the piston pusher is slidably connected with a plurality of limiting rods, the plurality of limiting rods being evenly distributed on the mounting plate, and the mounting plate being installed on the inner wall of the transverse sewage pipe.

[0016] As a preferred embodiment of the present invention, a slider is fixedly mounted at the bottom of the switch rod, a slide bar is slidably connected to the inner wall of the slider, and the slide bar is fixedly mounted on the outer wall of the transverse sewage pipe.

[0017] As a preferred embodiment of the present invention, the length of the piston pusher is longer than the length between the connecting housing and the tube cover.

[0018] The present invention has the following beneficial effects:

[0019] 1. The wastewater discharge device of this air separation unit drives the motor to rotate the push screw, and the piston pusher moves towards the pipe cover. The piston pusher pushes the dirt in the transverse wastewater pipe towards the pipe cover, gradually pushing the dirt out of the transverse wastewater pipe. Then the piston pusher moves towards the motor, at which point the dirt enters the transverse wastewater pipe from the connecting housing. Then the piston pusher continues to push, allowing the device to discharge dirt intermittently, thus solving the problem that the valve port will be blocked due to the dirt standing for a long time, requiring manual removal.

[0020] 2. The sewage discharge device of this air separation equipment moves by moving the piston pusher cylinder to drive the connecting rod. When the connecting rod moves, it can drive the adjusting block and the switch rod to move. When the switch rod moves, it can drive the gear to rotate. The rotation of the gear can drive the pipe cover to flip, so that the dirt in the horizontal sewage discharge pipe can be pushed out by the piston pusher cylinder. The pipe cover of this device is closed and opened by the movement of the piston pusher cylinder.

[0021] 3. The wastewater discharge device of this air separation unit, by disengaging the adjusting block from the connecting rod and inserting the adjusting block into the fixed slot on the fixed bracket, allows the switch rod to be locked by the adjusting block and the fixed bracket. When the piston pusher moves repeatedly in the transverse wastewater pipe, it can squeeze the dry dirt. After the dry dirt is squeezed and compressed, the adjusting block aligns with the fixed slot, and the adjusting block disengages from the fixed slot and is inserted into the connecting rod. Subsequently, when the piston pusher moves, it can open the pipe cover and discharge the clumps of dirt. This device can process and discharge both dry and wet dirt. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-8 A wastewater discharge device for an air separation unit includes a wastewater discharge pipe 1 for the air separation unit, a connecting housing 2 fixedly mounted at the bottom of the wastewater discharge pipe 1, and a wastewater discharge assembly 3 fixedly mounted at the bottom of the connecting housing 2.

[0036] In the above structure, the dirt accumulated at the bottom of the air separation equipment drain pipe 1 can be discharged through the drain component 3 by setting the drain component 3. When the drain component 3 is opened, the dirt at the bottom of the air separation equipment drain pipe 1 falls into the drain component 3 through the connecting housing 2, so that the dirt enters the interior of the drain component 3.

[0037] The sewage discharge assembly 3 includes a sewage discharge mechanism 31, and an adjustment mechanism 32 is installed on the outer wall of the sewage discharge mechanism 31;

[0038] In the above structure, the sewage discharge mechanism 31 pushes the dirt to be discharged in a quantitative manner, which can effectively prevent dirt from clogging the equipment. By setting the adjustment mechanism 32, the state of dirt discharge can be changed. When the adjustment mechanism 32 is closed, thin dirt can be discharged. When the adjustment mechanism 32 is open, dry dirt can be squeezed and formed, so that the dirt is discharged from the equipment in a block form, which improves the flexibility of the device.

[0039] The sewage discharge mechanism 31 includes a transverse sewage discharge pipe 3101, a piston pusher 3105 slidably connected to the inner wall of the transverse sewage discharge pipe 3101, a pusher screw 3104 threadedly connected to the inner wall of the piston pusher 3105, the pusher screw 3104 fixedly sleeved on the power output shaft of the push motor 3103, the push motor 3103 fixedly mounted on the transverse sewage discharge pipe 3101, and a connecting rod 3108 fixedly mounted on the outer wall of the piston pusher 3105.

[0040] In the above structure, the drive motor 3103 drives the drive screw 3104 to rotate clockwise. At this time, the drive screw 3104 can drive the piston push cylinder 3105 to slide in the transverse drain pipe 3101, so that the dirt in the transverse drain pipe 3101 can be pushed by the piston push cylinder 3105. Gradually, the piston push cylinder 3105 moves in the opposite direction to the drive motor 3103 to push the dirt out of the transverse drain pipe 3101.

[0041] The adjustment mechanism 32 includes an adjustment block 3201, which is slidably connected to the connecting rod 3108. A switch rod 3202 is slidably connected to the outer wall of the adjustment block 3201. A square groove 3203 is provided on the outer wall of the switch rod 3202, and a toothed groove 3204 is provided on the top of the switch rod 3202.

[0042] In the above structure, by setting the adjusting block 3201, when the adjusting block 3201 contacts the connecting rod 3108, the movement of the horizontal drain pipe 3101 can drive the connecting rod 3108 to move, the adjusting block 3201 connected to the connecting rod 3108 can move, and the switch rod 3202 installed on the adjusting block 3201 can also move. The adjusting block 3201 plays an adjusting role.

[0043] A fixed bracket 3212 is fixedly mounted on the outer wall of the horizontal sewage pipe 3101. A fixed groove 3213 is opened on the outer wall of the fixed bracket 3212. The adjusting block 3201 is slidably connected to the fixed groove 3213.

[0044] In the above structure, when the adjusting block 3201 slides into the fixed groove 3213, the adjusting block 3201 will disengage from the connecting rod 3108. At this time, the switch rod 3202 is fixed to the fixed bracket 3212 through the adjusting block 3201, so that the switch rod 3202 cannot move. When the switch rod 3202 does not move, it cannot drive the gear 3111 to rotate, so that the tube cover 3109 can be locked.

[0045] A fixed block 3211 is fixedly mounted on the outer wall of the adjusting block 3201, and a moving screw 3210 is fixedly mounted on the inner wall of the fixed block 3211. An adjusting worm wheel 3209 is threadedly connected to the outer edge of the moving screw 3210, and the adjusting worm wheel 3209 is movably connected to the switch rod 3202.

[0046] In the above structure, when the adjusting worm gear 3209 rotates, it can drive the moving screw 3210, the fixed block 3211, and the adjusting block 3201 to move in the switch rod 3202, gradually moving the adjusting block 3201 into the fixing groove 3213 on the fixed bracket 3212, so that the adjusting block 3201 can disengage from the connecting rod 3108. By reversing the adjusting worm gear 3209, the adjusting block 3201 can be disengaged from the fixing groove 3213 on the fixed bracket 3212, and gradually inserting the adjusting block 3201 into the connecting rod 3108, so that the connecting rod 3108, the adjusting block 3201, and the switch rod 3202 can be connected.

[0047] The adjusting worm gear 3209 is threadedly connected to the outer edge of the adjusting worm 3207. An adjusting handle 3208 is fixedly mounted on the outer edge of the adjusting worm 3207. The adjusting worm 3207 is movably connected to the switch rod 3202.

[0048] In the above structure, by adjusting the cooperation between the worm gear 3207 and the worm wheel 3209, the worm gear 3207 and the worm wheel 3209 have a self-locking function, so that the adjusting block 3201 will not move when the switch rod 3202 moves, so that the adjusting block 3201 is in stable contact with the connecting rod 3108, thereby improving the stability of the device.

[0049] A horizontal groove 3102 is provided on the outer wall of the horizontal drain pipe 3101, and the connecting rod 3108 is slidably connected to the horizontal groove 3102.

[0050] In the above structure, since the piston pusher 3105 is located in the inner cavity of the transverse drain pipe 3101, the power for the movement of the connecting rod 3108 comes from the movement of the piston pusher 3105. Therefore, a transverse groove 3102 needs to be opened on the outer wall of the transverse drain pipe 3101. When the piston pusher 3105 moves, the connecting rod 3108 will slide on the transverse groove 3102, which improves the rationality of the device.

[0051] A pipe cover 3109 is provided at the end of the horizontal drain pipe 3101 away from the drive motor 3103. The pipe cover 3109 is installed on the horizontal drain pipe 3101 through a connecting shaft 3110. The connecting shaft 3110 is movably connected to the horizontal drain pipe 3101.

[0052] In the above structure, the pipe cover 3109 can seal the outlet of the transverse drain pipe 3101. When wet dirt is encountered, the pipe cover 3109 can be opened, allowing the dirt to be discharged from the outlet of the transverse drain pipe 3101. When dry dirt is encountered, the pipe cover 3109 is closed, blocking the dry dirt. The piston pusher 3105 repeatedly pressurizes the dry dirt, causing it to be squeezed into shape. Then the pipe cover 3109 can be opened, and the discharged dirt is in block form.

[0053] Gears 3111 are installed at both ends of the connecting shaft 3110, and the gears 3111 mesh with the tooth groove 3204;

[0054] In the above structure, the movement of the piston pusher 3105 drives the connecting rod 3108 to move. The movement of the connecting rod 3108 drives the adjusting block 3201 and the switch rod 3202 to move. The switch rod 3202 can drive the gear 3111 to rotate. The rotation of the gear 3111 can drive the connecting shaft 3110 and the pipe cover 3109 to rotate, so that the pipe cover 3109 can be opened and the dirt can be discharged.

[0055] In a preferred embodiment, a plurality of limiting rods 3106 are slidably connected to the inner wall of the piston pusher 3105. The plurality of limiting rods 3106 are evenly distributed on the mounting plate 3107, which is installed on the inner wall of the transverse drain pipe 3101.

[0056] In the above structure, the limiting rod 3106 can limit the piston push cylinder 3105, so that the piston push cylinder 3105 can only move laterally and cannot rotate. Therefore, when the push screw 3104 rotates, it can drive the piston push cylinder 3105 to move, so that the dirt in the transverse drain pipe 3101 can be pushed out by the piston push cylinder 3105, which improves the rationality of the device.

[0057] In a preferred embodiment: a slider 3205 is fixedly mounted on the bottom of the switch rod 3202, and a slide bar 3206 is slidably connected to the inner wall of the slider 3205. The slide bar 3206 is fixedly mounted on the outer wall of the horizontal drain pipe 3101.

[0058] In the above structure, when the switch rod 3202 moves, it will drive the slider 3205 to move. At this time, the slider 3205 slides on the slide bar 3206. Through the cooperation between the slide bar 3206 and the slider 3205, the switch rod 3202 can always move in a horizontal state, which improves the stability of the engagement between the switch rod 3202 and the fixed block 3211.

[0059] In a preferred embodiment: the length of the piston cylinder 3105 is longer than the length between the connecting housing 2 and the cap 3109;

[0060] In the above structure, when the piston pusher 3105 contacts the mounting plate 3107, the mounting plate 3107 can seal the connecting housing 2, so that dirt cannot enter the transverse drain pipe 3101, and dirt cannot enter the push screw 3104 side through the connecting housing 2, so that dirt cannot be discharged through the transverse groove 3102 on the transverse drain pipe 3101.

[0061] Working principle: During operation, the motor 3103 drives the lead screw 3104 to rotate. At this time, the piston pusher 3105 moves towards the motor 3103, causing the dirt at the bottom of the air separation unit's drain pipe 1 to fall downwards into the transverse drain pipe 3101. Then, the motor 3103 drives the lead screw 3104 to rotate in the opposite direction, causing the piston pusher 3105 to slide on the limit rod 3106. The sliding piston pusher 3105 moves the dirt in the transverse drain pipe 3101 towards the pipe cover 3109. When the device is moved, it can move the connecting rod 3108. The moving connecting rod 3108 can move the adjusting block 3201 and the switch rod 3202. When the switch rod 3202 moves, it can rotate the gear 3111. The rotation of the gear 3111 can rotate the pipe cover 3109, allowing the dirt in the transverse drain pipe 3101 to be pushed out by the piston pusher 3105. At this time, the piston pusher 3105 is still blocking the connecting housing 2. When the piston pusher 3105 is on the left side of the connecting housing 2, it is in the dirt-infeeding state. When it is necessary to dry the dirt... During block extrusion, rotating the adjusting handle 3208 drives the adjusting worm 3207 to rotate, which in turn drives the adjusting worm wheel 3209 to rotate. The rotation of the adjusting worm wheel 3209 moves the fixed block 3211, the moving screw 3210, and the adjusting block 3201, gradually disengaging the adjusting block 3201 from the connecting rod 3108. The adjusting block 3201 gradually enters the fixing groove 3213 on the fixed bracket 3212. At this time, the switch rod 3202 can be locked by the adjusting block 3201 and the fixed bracket 3212. When the piston pusher 3105 repeatedly... The piston pusher 3105 moves within the horizontal drain pipe 3101, allowing it to compress the dry dirt. Once the dry dirt is fully compressed, the motor 3103 drives the screw 3104 to rotate, causing the piston pusher 3105 and connecting rod 3108 to move. When the adjusting block 3201 aligns with the fixed groove 3213, the adjusting block 3201 is disengaged from the fixed groove 3213 and inserted into the connecting rod 3108. Subsequently, as the piston pusher 3105 moves, it can open the pipe cover 3109, allowing the piston pusher 3105 to discharge the clumps of dirt.
