Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to a sewage treatment device for titanium and titanium alloy processing. Background Art

[0002] During the production process of titanium and titanium alloy workpieces, it is often necessary to use equipment such as machine tools and lathes to perform operations such as cutting, drilling, and grooving on titanium and titanium alloy workpieces. During the processing, in order to cool the processing part and the tool tip, it is often necessary to use cooling water for flushing and cooling. In order to save water, the cooling water will be recycled and reused. The above processing will generate titanium and titanium alloy waste chips, which will be mixed into the cooling water and recycled together. In order to prevent the waste chips from being mixed into the cooling water and flushing on the product to cause scratches and wear on the product surface, therefore, it is necessary to filter the recycled cooling water to filter out the titanium and titanium alloy waste chips.

[0003] The existing sewage treatment devices for titanium and titanium alloy processing can effectively filter out and recycle titanium and titanium alloy waste chips. However, during the recycling process, since the titanium and titanium alloy waste chips are in an irregular curly and extended shape, they accumulate together, there are gaps between them, and the fluffiness is high. They occupy a large space during transportation and transfer, increasing the transportation cost. At the same time, it is difficult to arrange them neatly and fill them tightly, and it takes more time and manpower to perform the loading and transfer operations, reducing the recycling efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a sewage treatment device for titanium and titanium alloy processing that can compact the filtered waste chips for recycling, effectively solving the technical problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions.

[0006] A sewage treatment device for titanium and titanium alloy processing includes a filter box with an opening at the top. In the middle of the filter box, a filter plate is fixed. The filter plate has a number of uniformly arranged temporary storage grooves, and each temporary storage groove opens upward for temporarily storing the filtered waste chips. A driving mechanism is provided on the filter box. A number of wedge-shaped pressing blocks are arrayedly installed on the driving mechanism. The wedge-shaped pressing blocks are respectively distributed in the temporary storage grooves and are slidably fitted with the inner walls of the temporary storage grooves. The driving mechanism is used to drive each wedge-shaped pressing block to reciprocally translate along the length direction of the temporary storage groove to push the waste chips to move and cooperate with the inner wall of the filter box to compact the waste chips.

[0007] By providing a filter plate with a temporary storage groove, the filtered waste can be temporarily stored in the temporary storage groove. At the same time, a wedge-shaped pressing block is provided in each temporary storage groove. The driving mechanism drives the wedge-shaped pressing block to move along the temporary storage groove and push the waste in the temporary storage groove forward. Under the blocking effect of the inner wall of the filter box, the waste in the temporary storage groove is pushed together and compacted into waste cakes, so that the waste is more tightly combined together, the volume during recycling is reduced, the recycling cost is reduced, and the recycling is ensured to be more convenient and efficient.

[0008] Preferably, the filter plate is composed of several V-shaped plates fixedly connected in sequence, the bottom of each V-shaped plate is evenly distributed with several filter holes, each V-shaped plate has a temporary storage groove with a larger top and a smaller bottom, and the wedge-shaped pressure blocks are slidably installed in the V-shaped plates one by one.

[0012] Preferably, the driving mechanism includes a power track, a connecting arm, a suspension plate and a connecting rod. A connecting rod extending vertically upward to the top of the filter box is fixed to the top of each wedge-shaped pressure block, and a suspension plate is commonly fixed to the top of each connecting rod. The power track is fixed to the side of the filter box along the length direction of the temporary storage tank. The power track is provided with a movable seat that can be moved and adjusted. One end of the connecting arm is fixedly connected to the suspension plate, and the other end is fixedly connected to the movable seat.

[0013] Preferably, a number of first partition plates are evenly distributed in the filter box. The filter box is divided by the first partition plates into a number of diversion chambers. The bottom ends of the diversion chambers communicate with the top of the temporary storage tank in a one-to-one correspondence. A diverter is provided above the filter box, and the diverter is used to divert the recycled cooling water into each diversion chamber.

[0014] Preferably, the diverter is composed of a diversion box, an inlet part, and a number of diversion pipes. The inlet part is arranged at the top of the diversion box. The diversion box is divided by a guide plate into a number of diversion channels all communicating with the inlet part. A number of diversion pipes are arranged in an array at the bottom of the diversion box. The top of each diversion pipe communicates with the diversion channel in a one-to-one correspondence, and the bottom corresponds to the position of each diversion chamber.

[0015] Preferably, vertical guide rods extending upward are respectively fixed on both sides of the filter box. Support frames are respectively fixed on both sides of the diversion box.

A vertically extending first electric push cylinder is fixedly installed on the side of the filter box through a mounting table. The end of the telescopic rod of the first electric push cylinder is fixedly connected to a connecting frame fixed on the side of the diversion box.

[0016] Preferably, the sewage treatment device further includes a base. Two vertically extending stand frames are fixed above the base. The filter box is fixed on the tops of the two stand frames. A filter and a pressure pump are arranged above the base. The input part of the filter communicates with the discharge port at the bottom of the filter box. The drain port on the filter communicates with the input part of the pressure pump. The output part of the pressure pump communicates with the cooling water storage tank through a delivery pipe. A sewage discharge port for discharging the filtered fine particle impurities is also provided on the side of the filter.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0018] By providing a filter plate with a temporary storage tank, the present invention enables the filtered waste chips to be temporarily stored in the temporary storage tank. At the same time, wedge-shaped pressing blocks are arranged in each temporary storage tank. The driving mechanism works to drive the wedge-shaped pressing blocks to move along the temporary storage tank and push the waste chips in the temporary storage tank forward. Under the blocking effect of the inner side wall of the filter box, the waste chips in the temporary storage tank are pushed together and compacted into a waste chip cake, making the waste chips more tightly combined together, reducing the volume during recycling, lowering the recycling cost, and ensuring more convenient and efficient recycling.

[0019] Due to the special V-shaped structural design of the V-shaped plate in the present invention, the temporary storage tank in the V-shaped plate has a structure that is larger at the top and smaller at the bottom. During filtration, large-volume waste chips will get stuck at the upper layer of the temporary storage tank. As the depth of the temporary storage tank increases, the volume of waste chips that can be stuck becomes smaller, enabling the waste chips to be arranged in layers in the temporary storage tank. Furthermore, the fluffiness between the chips is high, which is conducive to the rapid passage of water and fine particles, improving the filtration speed. At the same time, the waste chips are arranged in layers in the temporary storage tank, which can prevent the waste chips from accumulating excessively at the bottom of the temporary storage tank and causing blockage of the filter holes, ensuring the continuous smoothness of the filter holes.

[0020] The present invention cooperates with the diverter and the diverter cavity separated by the partition in the filter box to divert the recovered water to each temporary storage tank for filtration, ensuring that the recovered water mixed with waste debris can be evenly distributed in each temporary storage tank, improving the uniformity during filtration, so that the temporary storage tank of each unit can fully exert the filtration effect, and avoiding excessive accumulation of waste debris in a local area, which causes excessive filtration burden in the local temporary storage tank, and effectively improving the filtration quality.

[0021] The present invention utilizes the end of the baffle plate to contact and squeeze the inner wall of the filter box to form a compaction cavity between the wedge-shaped pressure block and the side wall of the filter box. As the wedge-shaped pressure block continues to be fed, the space of the compaction cavity gradually decreases. The baffle plate is utilized to provide a blocking effect at the top of the temporary storage tank to enclose the waste chips in the compaction cavity for compaction, thereby ensuring the compaction molding quality of the waste chips and avoiding pressure leakage caused by the waste chips being pressed to move upward and pass over the wedge-shaped pressure block.

[0022] The present invention provides structures for discharging and collecting crumbs on both sides of the filter box, so that the wedge-shaped pressing block can compact and discharge waste crumbs twice in one round trip. Furthermore, after the wedge-shaped pressing block moves to the inner wall of one side of the filter box, it does not need to be immediately retracted and reset. When moving to the inner wall of the other side, the next waste crumb compaction can be completed, eliminating the time required for the wedge-shaped pressing block to retract and reset after unidirectional movement and compaction, thereby having high continuity and further improving the processing efficiency.

[0043] The sewage treatment device for titanium and titanium alloy processing includes a filter box 2 with an opening at the top. In the middle of the filter box 2, a filter plate 3 is fixed. There are several uniformly arranged temporary storage grooves 301 on the filter plate 3, and each temporary storage groove 301 opens upward for temporarily storing the filtered waste chips. Several first partition plates 21 are evenly distributed in the filter box 2, and the filter box 2 is divided into several diversion chambers 22 by the first partition plates 21. The bottom ends of the diversion chambers 22 communicate with the tops of the temporary storage grooves 301 in a one-to-one correspondence. Above the filter box 2, there is a diverter 7, and the diverter 7 is used to divert and introduce the recycled cooling water into each diversion chamber 22.

[0044] When the sewage treatment device for titanium and titanium alloy processing is in use, the cooling wastewater generated during processing and mixed with waste chips is recovered and transported into the diverter 7. The diverter 7 diverts and introduces the recovered water into each diversion chamber 22, and then the diversion chambers 22 introduce the recovered water into the temporary storage grooves 301 respectively. The filter plate 3 filters the recovered water, and the filtered cooling water flows to the lower part of the filter plate 3, while the filtered waste chips remain in the temporary storage grooves 301 for temporary storage.

[0045] Among them, the diverter 7 cooperates with the diversion chambers 22 separated by the first partition plates 21 in the filter box 2 to divert and conduct the recovered water into each temporary storage groove 301 for filtration, ensuring that the recovered water mixed with waste chips can be evenly distributed into each temporary storage groove 301, improving the uniformity during filtration, enabling the filtration function to be fully exerted in each unit of the temporary storage groove 301, and also preventing the waste chips from accumulating excessively in a local area, resulting in an overly heavy filtration burden in the local temporary storage groove 301.

[0046] A driving mechanism 5 is provided on the filter box 2. A number of wedge-shaped pressing blocks 4 are arrayedly installed on the driving mechanism 5. The wedge-shaped pressing blocks 4 are respectively distributed in the temporary storage grooves 301 and are slidably attached to the inner walls of the temporary storage grooves 301. The driving mechanism 5 is used to drive each wedge-shaped pressing block 4 to reciprocally translate along the length direction of the temporary storage groove 301 to push the waste chips to move and cooperate with the inner wall of the filter box 2 to compact the waste chips.

[0047] After a long time of filtering and treating the recovered water, when the waste chips temporarily stored in the temporary storage groove 301 reach a certain amount, at this time, the driving mechanism 5 works, driving the wedge-shaped pressing blocks 4 stored near the inner wall on one side of the filter box 2 to move along the temporary storage groove 301 towards the inner wall on the other side of the filter box 2. The moving wedge-shaped pressing blocks 4 can push the waste chips in the temporary storage groove 301 forward. Finally, under the blocking action of the inner wall of the filter box 2, the wedge-shaped pressing blocks 4 push the waste chips in the temporary storage groove 301 together and compact them into a waste chip cake, making the waste chips more closely combined together and reducing the volume during recovery.

[0048] Please refer to Figure 5 and Figure 6, the filter plate 3 is composed of a number of V-shaped plates 31 fixedly connected in sequence. A number of filter holes 32 are evenly distributed at the bottom of each V-shaped plate 31. During filtration, the waste chips are retained in the temporary storage tank 301, while the water body and fine particles pass through the filter holes 32 at the bottom of the V-shaped plate 31 and flow to the lower part of the filter plate 3. The inside of each V-shaped plate 31 is a temporary storage tank 301 with a larger upper part and a smaller lower part, and the wedge-shaped pressing blocks 4 are slidably installed in the V-shaped plates 31 in one-to-one correspondence.

[0049] The titanium and titanium alloy waste chips produced by processing have different volumes. Due to the special V-shaped structural design of the V-shaped plate 31, the temporary storage tank 301 inside the V-shaped plate 31 has a structure with a larger upper part and a smaller lower part. During filtration, as Figure 12 shown, the large-volume waste chips will get stuck at the upper layer of the temporary storage tank 301. As the depth of the temporary storage tank 301 increases, the volume of the waste chips that can be stuck becomes smaller, causing the waste chips to be arranged in layers in the temporary storage tank 301. Furthermore, the fluffiness between the chips is high, which is conducive to the rapid passage of the water body and fine particles, improving the filtration speed. At the same time, the waste chips are arranged in layers in the temporary storage tank 301, which can prevent the waste chips from accumulating excessively at the bottom of the temporary storage tank 301 and causing blockage of the filter holes 32, ensuring the continuous smoothness of the filter holes 32.

[0050] Please refer to Figure 7 and Figure 10 , through slots 41 are provided near the top of each wedge-shaped pressing block 4. A baffle 6 extending along the length direction of the temporary storage tank 301 is installed in each through slot 41 in a limited sliding manner. Vertical holes 42 extending upward and communicating with the through slots 41 are provided inside each wedge-shaped pressing block 4. A vertically upward extending spring 61 is fixed on the inner bottom wall of each hole 42. A connecting head 63 is fixed at one end of the top of the spring 61. A relief groove 601 extending along the length direction of the baffle 6 is provided on the lower surface of the baffle 6. A traction rope 62 is fixedly connected to the middle of the inner wall of the relief groove 601. The other end of the traction rope 62 extends into the hole 42 and is fixedly connected to the connecting head 63.

[0051] Among them, the traction rope 62 is made of flexible steel wire rope, which is not easy to break and has a long service life. The relief groove 601 provided at the bottom of the baffle 6 is used to accommodate the steel wire rope, preventing the steel wire rope from being directly arranged between the lower surface of the baffle 6 and the inner bottom wall of the through slot 41 and causing blockage, which affects the sliding of the baffle 6.

[0052] In addition, when the baffle 6 is not in contact and pressed against the inner wall of the filter box 2, the spring 61 is in a retracted state, and the lengths of the baffle 6 extending from both sides of the wedge-shaped pressing block 4 are the same. When the baffle 6 is in contact and pressed against the inner wall of the filter box 2, a compaction cavity 302 is formed between the inner walls on both sides of the temporary storage tank 301, the side walls of the wedge-shaped pressing block 4, the lower surface of the baffle 6, and the corresponding inner wall of the filter box 2.

[0053] Among them, when the end of the baffle 6 does not contact the inner wall of the filter box 2, due to the elastic force of the spring 61 and the restraint effect of the traction rope 62 on the baffle 6, the baffle 6 is in a reset state. At this time, the lengths of both ends of the baffle 6 extending out are the same. During the process of the driving mechanism 5 driving the wedge-shaped pressing block 4 to compact the waste chips, when the end of the baffle 6 contacts and presses against the inner wall of the filter box 2, as the wedge-shaped pressing block 4 continues to advance, the baffle 6 is pressed and moves relative to the wedge-shaped pressing block 4. As shown in Figure 14 , on the one hand, under the traction of the traction rope 62, the spring 61 is stretched and stores energy. On the other hand, a compaction cavity 302 is formed between the wedge-shaped pressing block 4 and the side wall of the filter box 2 and below the baffle 6. At the same time, as the wedge-shaped pressing block 4 continues to feed, the spring 61 is stretched longer, and the space of the compaction cavity 302 becomes smaller. The baffle 6 is used to enclose the waste chips in the compaction cavity 302 for compaction, which not only ensures the forming quality of the compacted waste chips but also avoids the situation of missed compaction due to the waste chips being pressed and moving upward over the wedge-shaped pressing block 4. During the retraction process of the wedge-shaped pressing block 4, under the elastic reset action of the spring 61, the baffle 6 is pulled back. After the baffle 6 is separated from the inner wall of the filter box 2, the baffle 6 returns to its original state again.

[0054] Please refer to Figure 3 and Figure 13 . At positions corresponding to both sides of the filter plate 3 on the filter box 2, discharge ports 23 are provided. Sealing plates 8 for blocking the discharge ports 23 are installed in both discharge ports 23. Side covers 81 covering the discharge ports 23 are fixed on both side surfaces of the filter box 2. A material collection box 83 with an opening at the bottom is formed between the side covers 81 and the side surface of the filter box 2. Second electric push cylinders 82 are fixed on both side covers 81. The telescopic rods of the second electric push cylinders 82 all penetrate and extend into the inside of the side covers 81 and are correspondingly fixed to the sealing plates 8. Among them, the sealing plates 8 block the discharge ports 23 and complete the inner wall of the filter box 2, so that the sealing plates 8 serve as a part of the inner wall of the filter box 2. During compaction, the wedge-shaped pressing block 4 specifically cooperates with the inner side surface of the sealing plate 8 to compact the waste chips.

[0055] When the waste chips are compacted into a chip cake, through the retraction of the second electric push cylinder 82, the sealing plate 8 is driven to disengage from the discharge port 23, so that the discharge port 23 is in an open state. Then, through the operation of the driving mechanism 5, the wedge-shaped pressing block 4 is continuously driven to feed, and the chip cake is pushed out from the discharge port 23 by the wedge-shaped pressing block 4 into the material collection box 83 formed by the side cover 81 and the outer surface of the filter box 2. The chip cake falling into the material collection box 83 falls vertically. By arranging a collection container below the opening at the bottom of the material collection box 83, the chip cake can be collected. After collection, through the operation of the second electric push cylinder 82, the sealing plate 8 is pushed back into the discharge port 23 to block the discharge port 23 for the next waste chip compaction work.

[0056] Secondly, by arranging structures for discharging and collecting chip cakes on both sides of the filter box 2, the wedge-shaped pressing block 4 can compact and discharge waste chips twice during a round trip. Furthermore, after the wedge-shaped pressing block 4 moves to the inner wall of one side of the filter box 2, it does not need to immediately retreat and reset. When moving to the inner wall of the other side, it can then complete the next compaction of waste chips, saving the time for the wedge-shaped pressing block 4 to retreat and reset during one-way movement compaction, with high continuity and further improving the processing efficiency.

[0057] Please refer to Figure 2 、 Figure 3 、 Figure 8 and Figure 9 , the diverter 7 is composed of a diversion box 71, an inflow part 72 and a plurality of diversion pipes 73. The inflow part 72 is arranged at the top of the diversion box 71. A plurality of diversion channels 712 communicating with the inflow part 72 are separated in the diversion box 71 through a guide plate 711. The plurality of diversion pipes 73 are arranged in an array at the bottom of the diversion box 71. The tops of the respective diversion pipes 73 are correspondingly connected to the diversion channels 712 one by one, and the bottoms correspond to the positions of the respective diversion cavities 22. The recovery pipe is placed in the inflow part 72 to introduce the recovered water into the diversion box 71. The water body is diverted into the respective diversion channels 712 through the guide plate 711 and finally flows into the diversion pipes 73.

[0058] Secondly, guide rods 701 extending vertically upward are respectively fixed on both sides of the filter box 2. Support frames 702 are respectively fixed on both sides of the diversion box 71. The two support frames 702 are respectively sleeved on the corresponding guide rods 701 in a sliding manner. A vertically extending first electric push cylinder 704 is fixedly installed on the side of the filter box 2 through a mounting table 703. The end of the telescopic rod of the first electric push cylinder 704 is fixedly connected to a connecting frame 705 fixed on the side of the diversion box 71.

[0059] By the retraction operation of the first electric push cylinder 704, under the connection action of the connecting frame 705, the diversion box 71 can be driven to move downward along the guide rod 701. As Figure 13 shown, when the diversion box 71 moves downward to the limit position, the bottom ends of the respective diversion pipes 73 are respectively inserted into the temporary storage grooves 301, and the recovered water can be directly diverted and conveyed into the respective temporary storage grooves 301 to ensure the uniform distribution of the recovered water.

[0060] As Figure 4 and Figure 7As shown in the figure, the driving mechanism 5 includes a power track 51, a connecting arm 53, a suspension plate 54 and a connecting rod 55. A connecting rod 55 extending vertically upward above the filter box 2 is fixed to the top of each wedge-shaped pressing block 4. A suspension plate 54 is fixedly connected to the tops of the connecting rods 55. The power track 51 is fixed to the side of the filter box 2 along the length direction of the temporary storage groove 301. A movable seat 52 capable of moving and adjusting is provided on the power track 51. One end of the connecting arm 53 is fixedly connected to the suspension plate 54, and the other end is fixedly connected to the movable seat 52. By the operation of the power track 51, the movable seat 52 is driven to perform translational adjustment. Under the connection action of the connecting arm 53, the suspension plate 54 and each connecting rod 55, each wedge-shaped pressing block 4 can be driven to move synchronously, providing stable driving for the pushing and chip pressing actions of the wedge-shaped pressing blocks 4. Moreover, the movement of the movable seat 52 has a reciprocating effect, which is adapted to the compaction and discharging actions on both sides.

[0061] Secondly, when the shunt box 71 descends to the limit position, during the movement of the wedge-shaped pressing block 4, the shunt pipe 73 will cause blocking interference to the movement of the suspension plate 54 and the connecting rod 55. Therefore, when the wedge-shaped pressing block 4 moves, the first electric push cylinder 704 extends to work, pushing the shunt device 7 to move upward as a whole, so that the shunt pipe 73 moves above the suspension plate 54 to avoid blocking interference and ensure that the wedge-shaped pressing block 4 can move and adjust smoothly.

[0062] As Figure 1 and Figure 11 shown in the figure, the sewage treatment device further includes a base 1. Two vertically extending upright frames 11 are fixed above the base 1. The filter box 2 is fixed to the tops of the two upright frames 11. A filter 9 and a pressure pump 91 are arranged above the base 1. Among them, the filter 9 adopts the prior art, and its specific structure and working principle will not be elaborated in detail. The input part of the filter 9 is communicated with the discharge port 201 at the bottom of the filter box 2. The drain port 901 on the filter 9 is communicated with the input part of the pressure pump 91. The output part of the pressure pump 91 is communicated with the cooling water storage tank through a conveying pipe 92. A sewage discharge port 902 for discharging the filtered fine particle impurities is also provided on the side of the filter 9.

[0063] The water body mixed with fine particles after filtration flows into the filter 9 through the discharge port 201. The fine particles in the water body can be further filtered through the filter 9 to improve the treatment quality of the cooling water. The filtered water body enters the pressure pump 91 through the drain port 901, is pumped into the conveying pipe 92 by the pressure pump 91, and flows back to the cooling water storage tank through the conveying pipe 92 for the reuse of the cooling water. The filtered fine particle impurities are discharged through the sewage discharge port 902 for collection, so as to extract and recover the useful components in them more refinedly.

[0064] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
