Description

Technical Field

[0001] The invention relates to the technical field of pigment wastewater production, and in particular to a pretreatment device for organic pigment production wastewater. Background Art

[0002] The wastewater produced during the production of organic pigments has complex components, mainly including unreacted raw materials, by-products, pigment particles, organic solvents, etc. The concentration and properties of these components in the wastewater will affect the treatment method and effect of the wastewater.

[0003] Therefore, before treating organic pigment wastewater, it is necessary to treat the wastewater in a targeted manner according to its composition in order to better treat the wastewater. In the traditional detection process, sampling is required. Due to the differences in wastewater composition at different depths, the traditional sampling method has certain limitations and cannot comprehensively evaluate the composition of organic pigment wastewater.

[0004] Therefore, a device is needed that can more conveniently allow workers to pre-treat organic pigment wastewater, so as to more comprehensively collect the components of the organic pigment wastewater and facilitate subsequent treatment operations. Summary of the invention

[0005] The purpose of the present invention is to solve the above-mentioned problem and to propose a pretreatment device for organic pigment production wastewater.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A pretreatment device for organic pigment production wastewater, comprising: A filter chamber, wherein the filter chamber is rotatably connected to a rotating chamber, and both the filter chamber and the rotating chamber are made of transparent material, a circular groove is provided in the filter chamber, and the circular groove is connected to the surrounding edge of the filter screen by a thread; A round rod, the round rod is rotatably connected to the inner bottom wall of the rotating bin, and a vertical hole slidably connected to the round rod is provided on the filter screen, a limiting piece for limiting the filter screen is provided on the filter bin, a connecting port is provided at the bottom of the rotating bin, and a connecting pipe is fixed at the bottom of the rotating bin, the connecting port is communicated with the pipe mouth of the connecting pipe, a separating piece for separating the pigment wastewater precipitation from the wine is provided in the rotating bin and the filtering bin, and a matching piece for closing the connecting port is provided on the rotating bin; The collecting pot is provided below the connecting pipe, and the spout of the collecting pot extends into the lower end of the connecting pipe, and a filter is sleeved on the spout of the collecting pot.

[0008] Preferably, the limiting member includes a cover plate slidably connected to the circular groove of the filter bin, and the cover plate is provided with a middle hole slidably connected to the round rod, a connecting frame is fixed to the cover plate, and the connecting frame is provided with a through hole slidably connected to the round rod, and the filter screen moves in the vertical direction together with the cover plate through the adjusting member.

[0009] Preferably, the adjusting member comprises a vertical block fixedly connected to the peripheral edge, and a corresponding groove slidably connected to the vertical block is formed on the cover plate.

[0010] Preferably, the matching piece includes a rotating handle rotatably connected to the rotating bin, and the rotating handle is fixed with an arc block, and a rubber block for closing the connection port is fixed to the bottom of the arc block.

[0012] Preferably, the bottom of the collecting pot is provided with anti-slip protrusions.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present application, impurities in the pigment wastewater will fall downward under the action of gravity. Since the upper surface of the baffle and the upper surface of the connecting block are both inclined surfaces, the impurities in the pigment wastewater will fall to the bottom of the rotating bin through the baffle and the connecting block until the pigment wastewater is clarified. The impurities in the pigment wastewater will also gather at the bottom of the rotating bin. The baffle is controlled to move downward in the rotating sleeve until the card block at the bottom of the baffle is engaged with the card hole. At this time, the clarified pigment wastewater above the baffle is separated from the pigment wastewater mixed with impurities below the baffle, which is convenient for the subsequent treatment of the pigment wastewater above and below the baffle.

[0014] 2. The present application rotates the handle until the rubber block at the bottom of the arc-shaped block is separated from the connecting port at the bottom of the rotating bin. At this time, the impurities in the pigment wastewater in the rotating bin can pass through the connecting port and the connecting tube, and fall into the collection pot after being filtered by the filter tip, thereby effectively avoiding the waste of pigment wastewater. The pigment wastewater above the baffle and the pigment wastewater mixed with impurities below the baffle are treated separately, which effectively increases the efficiency of pigment wastewater filtration. When treating the pigment wastewater above the baffle, there is no need to worry about the mixing of impurities below the baffle, which facilitates the separate sampling, analysis and detection of impurities in the pigment wastewater.

A circular groove 3 is opened in the filter chamber 1, and the circular groove 3 is connected to the surrounding edge 5 of the filter screen 4 through a thread; The outer walls of the filter chamber 1 and the rotating chamber 2 are respectively fixed with a handle 11 and a handle 2 12, and both the handle 1 11 and the handle 2 12 are provided with anti-slip pads, so that the filter chamber 1 and the rotating chamber 2 can be more conveniently controlled by the handle 1 11 and the handle 2 12; The round rod 6 is rotatably connected to the inner bottom wall of the rotating bin 2, and the filter screen 4 is provided with a vertical hole 8 slidably connected to the round rod 6, the filter bin 1 is provided with a limiter for limiting the filter screen 4, the bottom of the rotating bin 2 is provided with a connecting port 24, and a connecting pipe 28 is fixed to the bottom of the rotating bin 2, the connecting port 24 is communicated with the pipe mouth of the connecting pipe 28, the rotating bin 2 and the filtering bin 1 are provided with a separation part for separating the pigment wastewater precipitation from the wine, and the rotating bin 2 is provided with a matching part for closing the connecting port 24; A collecting pot 29 is provided below the connecting tube 28, and the spout of the collecting pot 29 extends into the lower end of the connecting tube 28. A filter tip 30 is also sleeved on the spout of the collecting pot 29, and an anti-slip protrusion is provided at the bottom of the collecting pot 29, so that the collecting pot 29 can more stably support the filtering bin 1 and the rotating bin 2.

[0018] Specifically, Figure 1 As shown, the separation member includes a rotating sleeve 14 connected to the inner wall of the rotating bin 2 by threads, and a slider 15 is fixed on the outer wall of the rotating sleeve 14, a sliding groove 13 slidably connected to the slider 15 is provided on the inner wall of the filter bin 1, a plurality of connecting blocks 16 are fixed on the inner wall of the rotating sleeve 14, and a clamping hole 17 is formed between adjacent connecting blocks 16, the connecting block 16 is slidably connected to the round rod 6, a baffle 19 is slidably connected to the inner wall of the rotating sleeve 14, and a screw hole 21 connected to the round rod 6 by threads is provided on the baffle 19, an opening 22 aligned with the connecting block 16 is provided on the baffle 19, a clamping block 23 engaged with the clamping hole 17 is fixed to the bottom of the baffle 19, that is, when the connecting block 16 abuts against the baffle 19, the clamping block 23 blocks the clamping hole 17, a vertical groove 18 is provided on the inner wall of the rotating sleeve 14, and a side block 20 slidably connected to the vertical groove 18 is fixed on the outer wall of the baffle 19.

[0019] The surface of the connecting block 16 is an inclined surface, so when the impurities in the pigment wastewater fall onto the connecting block 16, they will slide downward along the surface of the connecting block 16 until the impurities slide to the bottom of the rotating bin 2. The upper surface of the baffle 19 is also inclined, and the opening 22 is located at the lowest point of the inclined surface, that is, the impurities in the pigment wastewater on the upper surface of the baffle 19 can slide to the opening 22 along the inclined surface of the upper surface of the baffle 19.

[0020] Specifically, Figure 3 As shown, the stopper includes a cover plate 7 slidably connected to the circular groove 3 of the filter bin 1, and the cover plate 7 is provided with a middle hole 33 slidably connected to the round rod 6, a connecting frame 9 is fixed to the cover plate 7, and the connecting frame 9 is provided with a through hole 10 slidably connected to the round rod 6, and the filter screen 4 moves in the vertical direction together with the cover plate 7 through the adjusting member. The cover plate 7 is slidably connected to the circular groove 3 until the cover plate 7 abuts against the filter screen 4, so that the filter bin 1 can be closed to prevent impurities and other substances from entering the filter bin 1.

[0021] Specifically, Figure 3 As shown, the adjusting member includes a vertical block 31 fixedly connected to the surrounding edge 5, and a corresponding groove 32 slidably connected to the vertical block 31 is provided on the cover plate 7. When the vertical block 31 is inserted into the corresponding groove 32, the cover plate 7 and the filter screen 4 can be rotated together by rotating the connecting frame 9, thereby changing the vertical height of the filter screen 4 and removing the filter screen 4 from the filter chamber 1 until the filter screen 4 is separated from the round rod 6.

[0022] Specifically, Figure 3 As shown, the matching part includes a rotating handle 27 that is rotatably connected to the rotating bin 2, and the rotating handle 27 is fixed with an arc block 25, and a rubber block 26 that closes the connection port 24 is fixed to the bottom of the arc block 25. The rubber block 26 is elastic, so when the arc block 25 moves, the rubber block 26 can extend into the connection port 24, thereby closing the connection port 24, effectively preventing the liquid in the rotating bin 2 from passing through the connection port 24 and then flowing into the collection pot 29 through the connecting pipe 28.

[0023] In summary, when the fermented pigment wastewater provided in this embodiment is filtered: The filter tip 30 is put on the collecting pot 29, and then the spout of the collecting pot 29 and the filter tip 30 are inserted into the pipe opening at the lower end of the connecting pipe 28, thus completing the installation of the collecting pot 29 and the connecting pipe 28.

[0024] The position of the rotating bin 2 is controlled by the second handle 12, and then the filter bin 1 is controlled to rotate by the first handle 11. Since the slider 15 on the outer wall of the rotating sleeve 14 is vertically slidably connected with the slide groove 13 provided on the filter bin 1, the filter bin 1 will drive the rotating sleeve 14 to rotate together during rotation. Since the rotating sleeve 14 is connected to the rotating bin 2 by threads, the rotating sleeve 14 moves vertically upward in the rotating bin 2. At this time, the bottom of the rotating sleeve 14 is away from the inner bottom wall of the rotating bin 2, that is, the space between the bottom of the rotating sleeve 14 and the inner bottom wall of the rotating bin 2 becomes larger. The amount of impurities is roughly judged according to the amount of pigment wastewater that needs to be filtered, so as to determine the upward movement distance of the rotating sleeve 14 in the rotating bin 2.

[0025] Until the rotating sleeve 14 moves to a suitable height in the rotating chamber 2, the positions of the filter chamber 1 and the rotating chamber 2 are then controlled by the handle 11 and the handle 2 12. The round rod 6 is then rotated to move the baffle 19 upward until the bottom of the baffle 19 is separated from the connecting block 16.

[0026] Control the position of the round rod 6, then the vertical hole 8 on the filter screen 4 can be connected to the round rod 6 through threads, and the middle hole 33 on the cover plate 7 and the through hole 10 on the connecting frame 9 can be put on the round rod 6. Until the cover plate 7 abuts against the surrounding edge 5 of the filter screen 4, and the vertical block 31 on the surrounding edge 5 extends into the corresponding groove 32 on the cover plate 7. By rotating the connecting frame 9, the cover plate 7 and the filter screen 4 can be rotated together until the filter screen 4 extends into the filter bin 1, and the surrounding edge 5 of the filter screen 4 abuts against the inner bottom wall of the circular groove 3, and the cover plate 7 can be removed.

[0027] The pigment wastewater to be filtered is poured into the filter bin 1. The pigment wastewater is filtered by the filter screen 4, and impurities are left on the filter screen 4 until all the pigment wastewater is poured into the filter bin 1. The filter screen 4 is taken out from the filter bin 1, and the impurities on the filter screen 4 are cleaned. The removal of the filter screen 4 can refer to the installation of the filter screen 4, which is not described here. Then, the cover plate 7 is slidably connected with the round rod 6 until the cover plate 7 abuts against the inner bottom wall of the circular groove 3 of the filter bin 1, and the cover plate 7 at this time closes the filter bin 1.

[0028] Wait for the pigment wastewater to be clarified, and you can directly check whether the pigment wastewater is clarified through the filtering chamber 1 and the rotating chamber 2.

[0029] Impurities in the pigment wastewater will fall downward under the action of gravity. Since the upper surface of the baffle 19 and the upper surface of the connecting block 16 are both inclined surfaces, the impurities in the pigment wastewater will fall to the bottom of the rotating bin 2 through the baffle 19 and the connecting block 16. The impurities in the pigment wastewater will also gather at the bottom of the rotating bin 2 until the pigment wastewater is clarified.

[0030] At this time, the filter chamber 1 and the rotating chamber 2 can be controlled by the handle 11 and the handle 2 12, and the position of the rotating sleeve 14 is also fixed, and the round rod 6 is rotated to make the baffle 19 move downward in the rotating sleeve 14 until the baffle 19 abuts against the connecting block 16, and the clamping block 23 at the bottom of the baffle 19 is engaged with the clamping hole 17, and the baffle 19 is now isolated from the top and bottom. That is, the clarified pigment wastewater above the baffle 19 is separated from the pigment wastewater mixed with impurities below the baffle 19.

[0031] By removing the cover plate 7 upward, the pigment wastewater in the filter chamber 1 can be poured out and collected, which is convenient for subsequent sampling and analysis. If there are still some impurities in the pigment wastewater in the filter chamber 1 at this time, the filter screen 4 can be installed with the filter chamber 1 again, so that after the pigment wastewater is poured out from the filter chamber 1, it will be filtered by the filter screen 4 again, and the poured pigment wastewater will be clearer and free of impurities, and the impurities will remain on the filter screen 4, which is convenient for subsequent collection and analysis.

[0032] By sampling and analyzing organic wastewater separately, the test results are more accurate and errors are avoided.

[0033] The pigment wastewater impurities in the rotating bin 2 are still mixed with pigment wastewater liquid. In order to avoid the waste of pigment wastewater, it can be filtered and processed: By rotating the handle 27 until the rubber block 26 at the bottom of the arc block 25 is separated from the connection port 24 at the bottom of the rotating bin 2, the impurities in the pigment wastewater in the rotating bin 2 can pass through the connection port 24 and the connecting pipe 28. After being filtered by the filter 30, the impurities fall into the collecting pot 29, effectively avoiding the waste of pigment wastewater. After the collecting pot 29 is separated from the connecting pipe 28, the filter 30 can be removed and the pigment wastewater in the collecting pot 29 can be poured out.

[0034] With the cooperation of the filter screen 4 and the filter tip 30, the organic pigment wastewater can be filtered multiple times, so that the impurities in the wastewater are separated from the wastewater, and the impurities and wastewater are detected separately, which is convenient for determining the method of wastewater treatment.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
