Description

Technical Field

[0002] Many industries today require organic matter and water-soluble salts for their operations, but these two substances may contaminate other substances after use, making them unusable. Nowadays, many contaminated substances are generally filtered and purified after use, and then the substances are buried in designated locations or transported to sewers to transport the contaminated substances away, or the pollutants are diluted, and then the mixed solution is placed in a filter mechanism for filtration, and then separated from the water-soluble salts. However, when the pollutants are diluted and the water-soluble salts are separated, the impurities in the mixed solution will accumulate on the filter net, which may cause the filter net to be blocked, resulting in a decrease in subsequent purification efficiency, or even inability to purify, which is inconvenient in actual use.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figures 1 to 11 :

[0033] A hazardous waste resource processing device comprises a frame, and a filter cartridge 1, a temporary storage box 2, a distillation component and a conveying component installed on the frame, wherein the filter cartridge 1 is provided with a liquid inlet 11, and a conical filter tube 12 for filtering impurities is provided at the bottom axis of the filter cartridge 1, the conical filter tube 12 has an inner diameter that decreases downward, and the circumference of the conical filter tube 12 is provided with filter holes evenly distributed, the conical filter tube 12 is located inside the temporary storage box 2 below the filter cartridge 1, and the temporary storage box 2 is provided with a liquid outlet 21, and the liquid outlet 21 is connected to the input end of the distillation component; a blocking block 13 is provided inside the conical filter tube 12, and the outer diameter of the blocking block 13 is The inner diameter of the sealing block 13 is the same as the inner diameter of the bottom opening of the conical filter tube 12. When the sealing block 13 is located at the bottom of the conical filter tube 12, the bottom opening of the conical filter tube 12 is blocked. A scraper 14 is slidably installed at the bottom of the sealing block 13. The scraper 14 moves radially along the sealing block 13 to fit the inner wall of the conical filter tube 12. The filter cartridge 1 is provided with a linear drive 15 for driving the sealing block 13 to move in a vertical direction, and a rotating drive 16 for driving the sealing block 13 to rotate around its own axis; a discharge pipe 121 is provided at the bottom of the conical filter tube 12, and the discharge pipe 121 extends to the outside of the temporary storage box 2. The filter cartridge 1 is provided with a waste collection box 3 at the discharge pipe 121.

[0034] When the treatment device of the present invention is in use, the staff will mix and dilute the pollutants with water, and then inject the mixed solution into the filter cartridge 1 through the liquid inlet 11 of the filter cartridge 1. The mixed solution moves to the temporary storage box 2 through the conical filter tube 12 at the bottom of the filter cartridge 1. The filter holes on the conical filter tube 12 retain the solid impurities in the conical filter tube 12. The solution enters the temporary storage box 2 and enters the distillation component through the liquid outlet 21 to separate the water and inorganic salts, and then is transported by the conveying component in a classified manner. The distillation component and the conveying component in this embodiment are prior art, which will not be described in detail here and are not shown in the figure. The conical filter tube 12 in this embodiment has a tapered downward taper, and the opening at the bottom of the conical filter tube 12 is blocked by the blocking block 13. Therefore, when the mixed solution enters the conical filter tube 12, the solution portion can only enter the temporary storage box 2 through the filter holes on the conical filter tube 12, and the solid impurities portion remains in the conical filter tube 12 and cannot pass through the blocking block 13 to enter the discharge pipe 121 below the conical filter tube 12. The staff can regularly use the linear drive 15 to move the blocking block 13 upward along the axis of the conical filter tube 12. After the blocking block 13 moves upward, the conical filter tube 12 The solid impurities in the filter tube 12 can enter the waste collection box 3 through the discharge pipe 121 for unified collection. During the upward movement of the blocking block 13, the scraper 14 at the bottom of the blocking block 13 moves radially along the blocking block 13 to fit the inner wall of the conical filter tube 12. During the subsequent downward movement of the blocking block 13, the rotary driver 16 can drive the blocking block 13 to rotate, and the scraper 14 moves along the inner wall of the conical filter tube 12 to clean up the impurities remaining in the filter holes on the conical filter tube 12, thereby avoiding the residue of impurities and ensuring the separation efficiency of the subsequent conical filter tube 12.

[0035] In order to solve the problem of how to make the solid impurities stuck in the filter holes escape from the filter holes and enter the discharge pipe 121, the following features are specifically set:

[0036] Two closed covers 4 are slidably installed in the temporary storage box 2. The closed covers 4 move radially along the conical filter tube 12. When the closed covers 4 are spliced ​​together, a cover body that closes the conical filter tube 12 is formed; each closed cover 4 is provided with an air inlet pipe 41, and the air inlet pipe 41 is connected to the working end of the air inlet assembly 5 arranged outside the filter cartridge 1.

[0037] Two closing covers 4 are also provided in the temporary storage box 2 in this embodiment. When the mixed solution enters the filter cartridge 1, the two closing covers 4 are located on both sides of the conical filter tube 12, and the solution enters the temporary storage box 2 through the gap between the conical filter tube 12 and the closing covers 4. When it is necessary to clean the impurities in the conical filter tube 12, the closing covers 4 are translated to merge, and the cover body spliced ​​by the two closing covers 4 seals the conical filter tube 12. The gas delivered by the air intake assembly 5 outside the filter cartridge 1 is blown into the conical filter tube 12 through the air intake pipe 41 on the closing cover 4, and the impurities remaining in the filter holes of the conical filter tube 12 are sent into the conical filter tube 12, and are cleaned by the sealing block 13 and the scraper 14 to the discharge pipe 121 and enter the waste collection box 3, to ensure that the filter holes on the conical filter tube 12 will not be blocked by impurities, thereby ensuring the efficiency of subsequent separation.

[0038] In order to solve the problem of how to ensure that the scraper 14 can maintain adaptive fit to the inner wall of the conical filter tube 12, the following features are specifically set:

[0039] A plug-in sleeve 131 is provided at the bottom of the blocking block 13, and a mounting block 141 is provided at one end of the scraper 14. The mounting block 141 is slidably installed in the plug-in sleeve 131. A first spring 132 is provided in the plug-in sleeve 131. The first spring 132 elastically connects the plug-in sleeve 131 and the mounting block 141. The elastic force of the first spring 132 makes the scraper 14 fit the inner wall of the conical filter tube 12; a lower fitting ring 122 is provided at the connection between the discharge pipe 121 and the conical filter tube 12, and the inner diameter of the lower fitting ring 122 is the same as the inner diameter of the bottom opening of the conical filter tube 12.

[0040] In this embodiment, the scraper 14 is slidably installed in the plug-in sleeve 131 below the blocking block 13 through the mounting block 141. The first spring 132 arranged in the plug-in sleeve 131 pushes the scraper 14 to move outward to fit the inner wall of the conical filter tube 12. When the blocking block 13 moves downward, the scraper 14 compresses the first spring 132 to move into the plug-in sleeve 131. When the blocking block 13 is located at the bottom of the scraper 14, one end of the scraper 14 close to the conical filter tube 12 fits the inner wall of the lower fitting ring 122. When the blocking block 13 keeps blocking the opening below the conical filter tube 12, the scraper 14 fits the lower fitting ring 122 and remains in the plug-in sleeve 131.

[0041] In order to solve the problem of how to ensure that the scraper 14 can fit the inner wall of the conical filter tube 12 at any position, the following features are specifically set:

[0042] The length of the scraper 14 is smaller than the diameter of the blocking block 13 ; the radius of the top opening of the conical filter tube 12 is smaller than the sum of the length of the scraper 14 and the radius of the blocking block 13 .

[0043] In this embodiment, the length of the scraper 14 is smaller than the diameter of the blocking block 13, and the radius of the top opening of the conical filter tube 12 is smaller than the sum of the length of the scraper 14 and the radius of the blocking block 13. Therefore, it can be ensured that the scraper 14 can completely enter the plug-in sleeve 131, and it can also be ensured that when the blocking block 13 moves to the top opening of the conical filter tube 12, the scraper 14 fits the inner wall of the conical filter tube 12 while keeping the mounting block 141 inside the plug-in sleeve 131, so as to prevent the scraper 14 from detaching from the plug-in sleeve 131 and affecting the subsequent cleaning operation.

[0044] In order to solve the problem of how to realize the blocking block 13 driving the scraper 14 to rotate and clean the inner wall of the conical filter tube 12, the following features are specifically set:

[0045] A spline shaft 133 is coaxially arranged on the top of the blocking block 13. The spline shaft 133 is inserted into the filter cartridge 1 and extends to the outside of the filter cartridge 1. A spline sleeve 161 and a drive wheel 162 are rotatably arranged on the top of the filter cartridge 1. The spline shaft 133 is installed in the spline sleeve 161. The spline sleeve 161 and the drive wheel 162 are connected by a transmission belt 163. The drive wheel 162 is coaxially installed on the working end of the rotary driver 16.

[0046] The rotation driver 16 in this embodiment can be a servo motor. The working end of the spline sleeve 161 drives the driving wheel 162 to rotate. The driving wheel 162 drives the spline sleeve 161 to rotate through the transmission belt 163. The spline shaft 133 on the blocking block 13 is installed in the spline sleeve 161. Therefore, when the spline sleeve 161 rotates, it can drive the spline shaft 133 and the blocking block 13 to rotate, and the spline shaft 133 can move vertically in the spline sleeve 161 to ensure the rotation effect of the blocking block 13.

[0047] In order to solve the problem of how to realize the vertical movement of the blocking block 13 in the axial direction of the conical filter tube 12, the following features are specifically set:

[0048] A limit swivel 134 is coaxially arranged at the top end of the spline shaft 133. The limit swivel 134 is rotatably mounted on a mounting sleeve 151. The mounting sleeve 151 is fixedly mounted on one end of a connecting frame 152. The connecting frame 152 is fixedly connected to the working end of the linear drive 15. The working end of the linear drive 15 is arranged to move in the vertical direction.

[0049] The linear drive 15 in this embodiment can be a cylinder, an oil cylinder or an electric push rod, etc. The working end of the linear drive 15 is connected to the connecting frame 152. The linear drive 15 can drive the connecting frame 152 to move in the vertical direction. The limiting swivel 134 is rotatably installed on the mounting sleeve 151 at the top of the connecting frame 152. When the spline shaft 133 rotates, it drives the limiting swivel 134 to rotate on the mounting sleeve 151, and the movement of the connecting frame 152 in the vertical direction can drive the rotating spline shaft 133 and the blocking block 13 to move in the vertical direction, ensuring that the scraper 14 fits the inner wall of the conical filter tube 12 for comprehensive cleaning.

[0050] In order to solve the problem of how to prevent impurities from re-entering the filter cartridge 1 when the air intake assembly 5 blows air into the conical filter tube 12, the following features are specifically set:

[0051] An upper fitting ring 123 is coaxially disposed on the top of the conical filter tube 12 , and the inner diameter of the upper fitting ring 123 is smaller than the diameter of the blocking block 13 .

[0052] The conical filter tube 12 in this embodiment is provided with an upper fitting ring 123 on the top. When the sealing block 13 moves to the upper opening of the conical filter tube 12, it can fit with the upper fitting ring 123 to seal the upper opening of the conical filter tube 12. At this time, the sealing cover 4 completely closes the conical filter tube 12. Therefore, the air delivered by the air intake assembly 5 can only blow the impurities remaining on the filter holes of the conical filter tube 12 into the conical filter tube 12 and move to the waste collection box 3 through the discharge pipe 121 to prevent solid impurities from re-entering the filter cylinder 1. Then, the rotary drive 16 drives the sealing block 13 to rotate, and the scraper 14 moves downward while fitting the conical filter tube 12 to sweep the impurities remaining on the inner wall of the conical filter tube 12 into the discharge pipe 121. Finally, the discharge pipe 121 is sealed again for subsequent processing.

[0053] In order to solve the problem of how the air intake assembly 5 can deliver gas into the closed cover 4 after the closed cover 4 closes the conical filter tube 12, the following features are specifically set:

[0054] The air intake assembly 5 includes two air boxes 51 fixedly installed on both sides of the filter cartridge 1, and an air source 52 fixedly installed on the outside of the filter cartridge 1, and the air boxes 51 are connected to the output ends of the air source 52 through air pipes; the air intake pipe 41 is composed of a first-stage pipe 411 and a second-stage pipe 412 coaxially arranged, and the first-stage pipe 411 extends horizontally to one side of the air intake pipe 41 close to the conical filter tube 12, and the diameter of the second-stage pipe 412 is larger than the diameter of the first-stage pipe 411; a horizontal blocking rod 511 is fixedly installed in the air box 51, and the diameter of the blocking rod 511 is the same as the inner diameter of the first-stage pipe 411. The blocking rod 511 is inserted in the first-stage pipe 411, and when the closing cover 4 is spliced ​​together, the blocking rod 511 is separated from the first-stage pipe 411.

[0055] In this embodiment, the air source 52 of the air intake assembly 5 can be a blower, etc. The working end of the air source 52 is connected to the air pipe, and the air pipe is connected to the air box 51 located on both sides of the filter cartridge 1. After the air enters the air box 51, it is injected into the air intake pipe 41 of the closed cover 4 and enters the closed cover 4. The air intake pipe 41 in this embodiment is composed of a first section pipe 411 and a second section pipe 412. When the closed cover 4 is in a separated state and away from the conical filter tube 12, the blocking rod 511 in the air box 51 is inserted into the first section pipe 411 of the air intake pipe 41 and blocks the first section pipe 411, so that the gas in the air box 51 is not The blocking rod 511 will be blown into the temporary storage box 2 through the air intake pipe 41 to affect the flow of the solution. When the closing cover 4 moves horizontally to the spliced ​​together to close the conical filter tube 12, the position of the air box 51 remains unchanged, and the blocking rod 511 is separated from the first section of the tube 411 as the air intake pipe 41 moves horizontally. Therefore, the air in the air box 51 can enter the first section of the tube 411 through the gap between the second section of the tube 412 and the blocking rod 511 to clean the filter holes of the conical filter tube 12. The existence of the blocking rod 511 ensures that the air intake assembly 5 can only supply air to the conical filter tube 12 after the closing cover 4 closes the conical filter tube 12.

[0056] In order to solve the problem of how to achieve the automatic sealing of the conical filter tube 12 by the sealing cover 4 after the sealing block 13 moves up to the top opening of the conical filter tube 12, the following features are specifically set:

[0057] At least two horizontal second guide rods 42 are provided on the side of the closing cover 4 away from the conical filter tube 12. The second guide rods 42 are inserted on both sides of the filter cartridge 1 and extend to the outside of the filter cartridge 1. A second spring 43 is sleeved on the second guide rod 42. The second spring 43 elastically connects the inner wall of the filter cartridge 1 and the closing cover 4. The elastic force of the second spring 43 causes the closing cover 4 to move toward the conical filter tube 12; one end of the second guide rod 42 located outside the filter cartridge 1 is connected to a connecting plate 44, and vertical side push plates 45 are provided on the connecting plates 44 on both sides of the filter cartridge 1. The side push plates 45 are located on the same side of the filter cartridge 1 and remain parallel; a vertically extending limiting groove 17 is provided on the outer wall of the filter cartridge 1 on one side of the side push plate 45, and the limiting groove 17 is located on the upper side of the side push plate 45. A horizontal insert is provided in the limiting groove 17 Plate 171; the air intake assembly 5 also includes a pressing block 53 slidably installed in the limiting groove 17, the width of the bottom of the pressing block 53 gradually decreases downward, and at least two vertically extending third guide rods 531 are arranged on the top of the pressing block 53, the third guide rods 531 are inserted on the insertion plate 171, and a third spring 532 is sleeved on the third guide rod 531, the third spring 532 elastically connects the insertion plate 171 and the top of the third guide rod 531, and the elastic force of the third spring 532 causes the pressing block 53 to move upward, and a horizontally extending contact plate 533 is arranged on the pressing block 53; a horizontal pressing plate 153 is arranged below the connecting frame 152, and when the linear drive 15 drives the blocking block 13 to move downward, the pressing plate 153 presses the contact plate 533 to insert the pressing block 53 between the two side push plates 45.

[0058] The closing cover 4 in this embodiment is inserted on the filter cartridge 1 through the second guide rod 42. The second spring 43 on the second guide rod 42 applies elastic force to bring the two closing covers 4 closer to each other until they fit the conical filter tube 12. When the linear drive 15 controls the connecting frame 152 to move downward, the blocking block 13 is located at the bottom opening of the conical filter tube 12. The pressing plate 153 at the other end of the connecting frame 152 moves downward and contacts the contact plate 533 on the pressing block 53, so that the pressing block 53 moves downward in the limiting groove 17 and compresses the third spring 532. When the pressing block 53 moves downward, the tip of the bottom of the pressing block 53 is inserted between the two side push plates 45. The two side push plates 45 are pushed apart to increase the distance between the two side push plates 45. The translation of the side push plates 45 drives the second guide rod 42 and the closing cover 4 to move through the connecting plate 44, so that the closing cover 4 compresses the second spring 43 and moves to the side away from the conical filter tube 12; when the linear drive 15 drives the blocking block 13 to move up to the top opening of the conical filter tube 12, the connecting frame 152 and the pressing plate 153 move up, and the lower pressing block 53 moves up under the elastic force of the third spring 532 until it is not in contact with the side push plates 45. At this time, the closing cover 4 can move closer to each other under the elastic force of the second spring 43 until they are spliced ​​together.

[0059] Working principle: When in use, the staff will mix and dilute the pollutants with water, and then inject it into the filter cartridge 1 through the liquid inlet 11 of the filter cartridge 1. The mixed solution moves to the temporary storage box 2 through the conical filter tube 12 at the bottom of the filter cartridge 1. The filter holes on the conical filter tube 12 retain the solid impurities in the conical filter tube 12. The solution enters the temporary storage box 2 and enters the distillation component through the liquid outlet 21 to separate the water and inorganic salts, and then is transported by the conveying component for classification. When the mixed solution enters the filter cartridge 1, the opening at the bottom of the conical filter tube 12 is blocked by the blocking block 13, and the solid impurities remain in the conical filter tube 12 and cannot pass through the blocking block 13 to enter the conical filter tube 12. In the discharge pipe 121 below the conical filter tube 12, the staff regularly uses the linear drive 15 to move the blocking block 13 upward along the axis of the conical filter tube 12. After the blocking block 13 moves upward, the solid impurities in the conical filter tube 12 can enter the waste collection box 3 through the discharge pipe 121 for unified collection. During the upward movement of the blocking block 13, the scraper 14 at the bottom of the blocking block 13 moves radially along the blocking block 13 to fit the inner wall of the conical filter tube 12. In the subsequent downward movement of the blocking block 13, the rotary drive 16 can drive the blocking block 13 to rotate, and the scraper 14 moves along the inner wall of the conical filter tube 12 to clean the impurities remaining in the filter holes on the conical filter tube 12.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
