Description

Technical Field

[0001] The present invention relates to a device for compressing waste stripping liquid residue into bricks, belonging to the technical field of detection. Background Art

[0002] Tank barrels are essential tools for modern warehousing and transporting liquid products. They are blow-molded from high-molecular-weight high-density polyethylene, with high strength, corrosion resistance, and good hygiene. An inlet is provided at the top, and an outlet is provided at the bottom of the side wall.

[0003] With the popularity of smart handheld devices and mobile terminals, the electronic manufacturing industry and optoelectronic industry have developed rapidly. Since in the manufacturing processes of printed circuit boards, liquid crystal display panels, semiconductor integrated circuits, etc., it is necessary to form multiple layers of precise microcircuits on silicon wafers or glass substrates through multiple processes such as graphic mask irradiation exposure and etching. Then, a stripping liquid is used to remove the photoresist coated on the protected area of the microcircuit as a mask. Usually, this step is called photoresist removal. In the wet processing production process of printed circuit boards, a large amount of stripping liquid will also be generated during the demolding (film stripping) process to remove the residual solder on the surface of waste circuit boards.

[0004] The generated stripping liquid needs to be stored and transported in tank barrels. At the same time, the stripping liquid contains residues. Before purifying the stripping liquid, solid-liquid separation needs to be carried out to filter and separate the residues. For example, in "CN111792984A A stripping liquid recovery device", it focuses on the recycling of stripping liquid, but there is no record on how to handle the separated residues.

[0005] The residue belongs to hazardous waste, which is the waste tar-like residue generated in other refining, distillation, and any pyrolysis processes as specified in the "List of Hazardous Wastes". In order to facilitate the subsequent treatment of the residue, it is necessary to compress the residue into bricks. Summary of the Invention

[0042] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] As Figures 1-10 shown:

[0044] The conveyor device 1 can adopt a belt conveyor and be horizontally arranged. The ton barrel 100 filled with stripping liquid is placed on the conveyor device 1, and the orientation of the ton barrel 100 is pre-adjusted / roughly adjusted.

[0045] On the opposite sides of the conveyor device 1, two groups of symmetrically arranged positioning mechanisms 3 are installed. The structure of the positioning mechanism 3 is as Figure 2 shown, including a first telescopic device 31, a base 32 installed at the output end of the first telescopic device 31, and a right-angle frame 33 rotatably connected to the upper surface of the base 32. The rotation angle of the right-angle frame 33 on the upper surface of the base 32 is limited, and a first elastic member (torsion spring) is also connected between the base 32 and the right-angle frame 33. The elastic force of the first elastic member drives the right-angle frame 33 to rotate and reset. The state of the right-angle frame 33 under normal conditions is as Figure 1 shown. At this time, the transverse end of the right-angle frame 33 is inclined to the conveying direction of the conveyor device 1.

[0046] The ton barrel 100 advances horizontally under the conveyance of the conveying device 1 until the front side wall of the ton barrel 100 abuts against the transverse ends of the two sets of right-angle frames 33. The ton barrel 100 continues to advance and pushes the two sets of right-angle frames 33 to rotate relative to each other until the transverse ends of the right-angle frames 33 are relatively perpendicular to the conveying direction of the conveying device 1 (the limit position is limited). During this process, the longitudinal ends of the two sets of right-angle frames 33 rotate accordingly and respectively abut against the left and right sides of the ton barrel 100 until the vertical ends of the two sets of right-angle frames 33 rotate to be parallel to each other 9 (parallel to the conveying direction of the conveying device 1). At this time, the distance between the vertical ends of the two sets of right-angle frames 33 is equal to the width of the ton barrel 100, thereby realizing the adjustment of the posture of the ton barrel 100.

[0047] The upper feeding port 101 on the upper surface of the ton barrel 100 after posture adjustment just aligns with the folding umbrella structure 4 above it. At the same time, the side discharging port 102 on the right side wall of the ton barrel 100 just aligns with the filter screen conveying device 2 and the opening mechanism 5.

[0048] After that, the staff starts the opening mechanism 5. As Figures 8-10 shown, the opening mechanism 5 includes a flipping assembly 51, a pressing rod 52, a rotating assembly 53, a turntable 54 and a number of elastic telescopic rods 55. The pressing rod 52 is in an "L" shape and its lower end is hinged relative to the ground. One end of the flipping assembly 51 can be an expansion cylinder, which is hinged relative to the ground and the other end is hinged to the pressing rod 52. Thus, the expansion and contraction of the expansion cylinder drives the pressing rod 52 to rotate relative to each other, so that the end of the pressing rod 52 with the turntable 54 approaches or moves away from the side discharging port 102 on the right side wall of the ton barrel 100. Since the operation handle states / orientations of the second valves 103 on the side discharging ports 102 of different ton barrels 100 are different when closed, therefore, a number of elastic telescopic rods 55 are installed on the turntable 54 in a rectangular array in sequence. The turntable 54 is rotationally connected to the pressing rod 52 through the rotating assembly 53 (which can be a motor), and the elastic telescopic rods 55 can automatically extend.

[0049] When the turntable 54 approaches the second valve 103, some of the elastic telescopic rods 55 in the rectangular array abut against the second valve 103 and are compressed, and the remaining elastic telescopic rods 55 maintain their lengths. At this time, the rotation center of the turntable 54 is roughly aligned with the rotation center of the second valve 103. Then the rotating assembly 53 drives the turntable 54 to rotate, and the several elastic telescopic rods 55 that maintain their lengths limit the periphery of the second valve 103, thereby driving the second valve 103 to rotate accordingly, so as to realize the opening / closing of the second valve 103 without manual / remote operation.

[0050] After the second valve 103 is opened, as Figures 5-6As shown, the stripping liquid in the ton barrel 100 is discharged through the side discharge port 102 and falls on the filter screen conveying device 2. A conveying pipeline 6 is arranged below the filter screen conveying device 2. The filter screen conveying device 2 includes a conveyor and a filter screen. The conveyor drives the filter screen to rotate in a cycle. After the stripping liquid is filtered by the filter screen, it falls into the conveying pipeline 6 below it. The filtered stripping liquid is conveyed outward through the conveying pipeline 6; while the residue in the stripping liquid remains on the filter screen, and the filter screen rotates in a cycle to drive the residue to move from left to right (ensuring that the stripping liquid has sufficient time to pass through the filter screen) and leave the discharge position of the side discharge port 102.

[0051] As Figure 6 shown, the residue conveying assembly 9 includes a collecting cover 91, a conveying hose 92, a first valve 93 and a jetting assembly 94. The collecting cover 91 is relatively located on the right side of the conveying pipeline 6. The jetting assembly 94 can adopt a nozzle and is connected to an external positive pressure air source. The jetting assembly 94 is placed inside the right side of the filter screen conveying device 2 and jets compressed air towards the collecting cover 91. The jetting assembly 94 jets compressed air to blow the residue adsorbed on the filter screen conveying device 2 / filter screen into the interior of the collecting cover 91; the residue inside the collecting cover 91 is conveyed to the brick forming mold 8 through the conveying hose 92. A first valve 93 is installed at the free end of the conveying hose 92 to control whether the residue inside it is discharged. The amount of residue in the stripping liquid is relatively small.

[0052] As Figure 5 and 7 shown, the brick forming mold 8 includes a hydraulic cylinder 7, a convex mold 81, a concave mold 82, a heating assembly 83, a jacking assembly 84 and a pushing seat 85. The concave mold 82 is relatively fixedly arranged. The output end of the hydraulic cylinder 7 is connected to the convex mold 81. The convex mold 81 and the concave mold 82 cooperate to form a mold. This is the prior art. Align the output end of the conveying hose 92 with the groove of the concave mold 82. After the residue in the groove of the concave mold 82 reaches a certain amount, the hydraulic cylinder 7 can be manually controlled to drive the convex mold 81 to descend vertically close to the convex mold 81. The convex mold 81 and the concave mold 82 cooperate to form a sealed cubic space, so as to compress the scattered residue into bricks; during this process, the heating assembly 83 heats the bricks to evaporate the moisture inside. Then the hydraulic cylinder 7 drives the convex mold 81 to rise vertically away from the convex mold 81, and the jacking assembly 84 (which can adopt a hydraulic cylinder) drives the pushing seat 85 to rise vertically, so as to push the bricks out of the groove of the concave mold 82.

[0053] As Figures 3-4As shown, the folding umbrella structure 4 includes a lifting device 41, a hollow umbrella handle 42, a second telescopic device 43, a limiting member 44, a fixing block 45, four groups of umbrella ribs 46, an umbrella surface 47, an elastic seal 48, and a jet head 49. The lifting device 41 can be relatively fixedly installed by using a telescopic cylinder. The downward output end of the lifting device 41 is fixedly connected to the hollow umbrella handle 42. The jet head 49 is installed at the lower end of the hollow umbrella handle 42. The air pipe of the jet head 49 is connected to the external positive pressure air source through the inside of the hollow umbrella handle 42. The fixing block 45 is relatively fixed at the lower part of the hollow umbrella handle 42 and above the jet head 49. The inner ends of the four groups of umbrella ribs 46 are all hinged to the fixing block 45. A second elastic member (torsion spring) is connected between the inner ends of the umbrella ribs 46 and the fixing block 45. The umbrella surface 47 is fixedly attached to the four groups of umbrella ribs 46. The elastic seal 48 is in a closed-loop structure and is fixed to the outer edge of the umbrella surface 47. The elastic seal 48 is relatively fixed to the outer ends of the four groups of umbrella ribs 46. The second telescopic device 43 can be installed on the middle part of the outer side wall of the hollow umbrella handle 42 by using an electric telescopic rod with an arbitrarily adjustable length. The output end of the second telescopic device 43 is provided with a limiting member 44. The second telescopic device 43 drives the limiting member 44 to move along the length direction of the hollow umbrella handle 42;

[0054] Under normal conditions, driven by the elastic force of the second elastic member 9 (not shown in the drawings), the umbrella ribs 46 are turned up and down and reset to the retracted state, which is beneficial to reducing the size. After the stripping liquid inside the ton barrel 100 is completely discharged, the lifting device 41 drives the umbrella ribs 46 to vertically descend through the upper feeding port 101 and into the ton barrel 100. Then, the second telescopic device 43 drives the limiting member 44 to descend and simultaneously abut against the four groups of umbrella ribs 46, thereby pushing the four groups of umbrella ribs 46 to rotate to the horizontal state, as Figures 3-4 shown. The second elastic member 9 generates a reverse elastic force. At this time, the umbrella surface 47 is in a horizontally unfolded state, and the outer edge of the umbrella surface 47 is in sealing contact with the inner side wall of the ton barrel 100 through the elastic seal 48;

[0055] Then, the external positive pressure air source evenly sprays air flow from the jet head 49 in all directions. The direction of the air flow is slightly inclined downward (0° - 5°) relative to the horizontal plane. The air flow blows the residue attached to the inner side wall of the ton barrel 100 downward. At this time, the upper feeding port 101 is isolated by the unfolded umbrella surface 47 and the elastic seal 48, so that most of the air flow is discharged outward from the side discharge port 102. Thus, it is beneficial to discharge most of the residue / stripping liquid attached to the inner side wall of the ton barrel 100 outward from the side discharge port 102. Avoid using water to cause mixing with the stripping liquid.

[0056] After that, the second telescopic device 43 continues to extend, driving the limiting member 44 to continue to descend. The limiting member 44 pushes the four groups of umbrella ribs 46 in the horizontal state that are in contact with it to continue to turn downward, realizing the downward turning and folding of the four groups of umbrella ribs 46. After that, the lifting device 41 drives the hollow umbrella handle 42 to rise vertically and separate from the upper feeding port 101. Then, the second telescopic device 43 shortens, driving the limiting member 44 to reset upward and separate from the contact with the four groups of umbrella ribs 46. Driven by the reverse elastic force of the second elastic member, the four groups of umbrella ribs 46 all turn upward and reset, so that the four groups of umbrella ribs 46 are in the folded state with upward turning.

[0057] During the process of the four groups of umbrella ribs 46 entering and exiting the upper feeding port 101, their inner ends pass through the upper feeding port 101 first, which can prevent the outer ends of the four groups of umbrella ribs 46 from deforming and resulting in a size larger than the inner diameter of the upper feeding port 101 and thus being unable to pass through smoothly.

[0058] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present invention.
