Description

Technical Field

[0001] This invention relates to the field of chemical waste treatment technology, specifically to a chemical waste collection and treatment device. Background Technology

[0002] Chemical wastewater refers to process wastewater, cooling water, exhaust gas scrubbing water, equipment and site washing water, etc., discharged during chemical production. If this wastewater is discharged without treatment, it will cause pollution of water bodies in different ways and to varying degrees, thereby endangering human health and affecting industrial and agricultural production. The chemical industry includes two major categories: organic chemicals and inorganic chemicals. Chemical products are diverse and have complex compositions. Wastewater discharged from chemical plants is called chemical wastewater. Chemical wastewater is diverse, most of which are highly toxic, difficult to purify, and have a certain accumulation effect in organisms. In water bodies, it has obvious oxygen-consuming properties and easily deteriorates water quality. Chemical waste liquids generally need to be recycled and treated before being discharged. However, the collection and treatment of chemical waste liquids often results in the collection of many precipitates in the waste liquid, increasing the difficulty of chemical waste liquid treatment. Therefore, a chemical waste liquid collection device is proposed.

[0003] For example, an environmental protection device for treating waste liquid in chemical plants that facilitates the collection of residues, as described in application number 201821032540.8, includes a container body. A collection bucket is placed inside the container body. Positioning plates are fixedly connected to both the left and right sides of the collection bucket. Each positioning plate has a limit hole on its upper surface. A filter plate adapted to the collection bucket is fixedly connected to the inner wall of the collection bucket. Two symmetrical load-bearing plates are fixedly connected to the inner wall of the container body, and the bottom surfaces of the two positioning plates are in contact with the upper surfaces of the two load-bearing plates, respectively.

[0004] For example, a chemical waste liquid collection device with application number 202122743040.3 includes a collection device body, an inlet hopper fixedly connected to the top of the collection device body, a scale fixedly installed on the left side of the collection device body, a filter cylinder inside the collection device body, an outlet pipe fixedly connected to the bottom of the filter cylinder, a filter plate slidably connected inside the filter cylinder, a reset spring and a connecting rod below the filter plate, and a pressure plate fixedly connected below the connecting rod.

[0005] However, current chemical waste treatment equipment, after separating waste residue and waste liquid, causes waste residue to accumulate, requiring cleaning. However, cleaning is too troublesome, requiring the disassembly of the filter device, cleaning, and reinstallation or the installation of a new filter device, which greatly reduces the efficiency of waste liquid treatment and also increases the labor intensity of the staff.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. By coordinating and cooperating with each other, the waste liquid pipeline, cleaning pipeline assembly, pipeline support assembly, lower pipeline structure, waste liquid tank, filter pipeline, digital display control panel and liquid level detection assembly can automatically separate and clean impurities in chemical waste liquid, thereby improving the treatment efficiency of chemical waste liquid.

[0023] 2. The first motor of the cleaning pipeline assembly can drive the spray pipe to deflect and rotate at a certain angle through a gear transmission mechanism, thereby adjusting the spray angle to achieve multi-directional cleaning of the filter screen and thoroughly cleaning and separating the impurities on the filter screen.

[0024] 3. The output shaft of the second motor of the pipe support assembly can drive the filter pipe to flip up and down, thereby flipping the filter screen inside the filter pipe. This allows impurities located on the upper side of the filter screen to be placed on the lower side of the filter screen after flipping, making it easier for the impurities to separate from the filter screen and fall off.

[0025] 4. When the time interval between the liquid level sensor of the liquid level detection component detecting the liquid level inside the filter pipe reaching a certain height becomes shorter and shorter and reaches a certain time, it indicates that the mesh of the filter screen is becoming more and more clogged and needs to be cleaned. At this time, the filter frame plate can be pulled out from the track slide for replacement and cleaning.

[0026] 5. Liquid and waste residue can be separated by a screen. The liquid falls into the tank and the waste residue falls into the slag collection chamber. The waste residue in the slag collection chamber can be cleaned out by opening the rotating cover. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0041] See Figure 1-11 As shown, the present invention provides a chemical waste liquid collection and treatment device, including a waste liquid pipeline 1, a filter pipeline 6 capable of solid-liquid separation, a lower-pass pipeline structure 4 capable of converting between liquid discharge and slag discharge, and a waste liquid tank 5 arranged from top to bottom. The waste liquid pipeline 1 is equipped with a liquid discharge on / off device capable of controlling its on / off state. The waste liquid pipeline 1 is equipped with a digital display control panel 7, which can control the liquid discharge on / off device. The waste liquid tank 5 is equipped with a pipeline support assembly 3 capable of supporting the waste liquid pipeline 1, the filter pipeline 6, and the lower-pass pipeline structure 4, adjusting the distance between the filter pipeline 6 and the waste liquid pipeline 1 and the lower-pass pipeline structure 4 respectively, and driving the rotation of the filter pipeline 6 and the lower-pass pipeline structure 4. The waste liquid pipeline 1 is equipped with a cleaning pipeline assembly 2 for cleaning the inside of the filter pipeline 6, and the waste liquid pipeline 1 is also equipped with a liquid level detection assembly 8 for detecting the liquid level inside the filter pipeline 6.

[0042] See instruction manual attached Figure 1 and4 As shown, the waste liquid pipeline 1 is vertically arranged, with a suspended pipeline 102 at its upper end. The upper end of the suspended pipeline 102 is open, and an end cap 103 is bolted to the opening. The cleaning pipeline assembly 2 is mounted on the suspended pipeline 102. One end of the discharge pipeline 101 is connected to the upper end of the waste liquid pipeline 1 below the suspended pipeline 102. A flange is mounted on the other end of the discharge pipeline 101. The waste liquid pipeline 1, the discharge pipeline 101, and the suspended pipeline 102 are integrally formed into a T-shape. A drain on / off device is mounted on the discharge pipeline 101. Through the above specific structural design, when the discharge pipeline 101 introduces waste liquid into the waste liquid pipeline 1, the waste liquid flows into the interior of the waste liquid pipeline 1 and will not affect the cleaning pipeline assembly 2.

[0043] See instruction manual attached Figure 5 , 6 As shown in Figure 10, this embodiment proposes a specific cleaning pipe assembly 2. The cleaning pipe assembly 2 includes a plurality of spray pipes 204 evenly arranged in the suspended pipe 102. These spray pipes 204 are distributed parallel to each other. Both ends of each spray pipe 204 are rotatably mounted on the side wall of the suspended pipe 102 via a first rotating shaft 205. The first rotating shafts 205 corresponding to the spray pipes 204 are connected to each other through a gear transmission mechanism 206. The shaft end of one spray pipe 204 is driven to rotate by a first motor 207 fixedly mounted on the suspended pipe 102. One end of a connecting pipe 203 is connected to the upper side of each spray pipe 204. The other end of the connecting pipe 203 passes through the end cap 103 and is connected to each other through a liquid distribution pipe 201. A pipe connector 202 is connected to the liquid distribution pipe 201. The output end of the digital display control panel 7 is electrically connected to the input end of the first motor 207. Through the above-mentioned specific structural design, the rotation of the output shaft of the first motor 207 can drive the connected first rotating shaft 205 to rotate. The rotation of the first rotating shaft 205 can drive the remaining spray pipes 204 to rotate at a certain angle through the gear transmission mechanism 206, thereby realizing the adjustment of the spray angle and realizing multi-directional cleaning of the filter screen 601, thereby cleaning and separating the impurities on the filter screen 601. With the help of the pipe support assembly 3 to flip the filter pipe 6 up and down, the impurities are located on the lower side of the filter screen 601. With the help of the cleaning pipe assembly 2, the filter screen 601 can be cleaned.

[0044] This embodiment proposes a specific pipe support assembly 3, which includes a bracket 307. The lower side of the bracket 307 is fixedly mounted on the waste liquid tank 5, and the upper side of the bracket 307 is fixedly mounted on the upper side. The upper support plate 304 is fixedly connected to the waste liquid pipe 1. Two central support plates 301 are symmetrically distributed on both sides of the filter pipe 6. The two sides of the filter pipe 6 are rotatably mounted between the two central support plates 301 via a third rotating shaft. The shaft end of one of the third rotating shafts is driven to rotate by a second motor 308 fixedly mounted inside the central support plate 301. The output end of the digital display control panel 7 is electrically connected to the input end of the second motor 308. The rotation of the output shaft of the second motor 308 can drive the filter pipe 6 to flip up and down, thereby flipping the filter screen 601 inside the filter pipe 6. This causes impurities located on the upper side of the filter screen 601 to be located on the lower side of the filter screen 601 after flipping, facilitating the separation and falling of impurities from the filter screen 601. The lower pipe structure 4 has two lower support plates 306 symmetrically distributed on both sides with the lower pipe structure 4 as the center. The two sides of the lower pipe structure 4 are rotatably set between the two lower support plates 306 by a second rotating shaft 310. The shaft end of one of the second rotating shafts 310 is driven to rotate by a third motor 309 fixedly set in the lower support plate 306. The output end of the digital display control panel 7 is electrically connected to the input end of the third motor 309. Each central support plate 301 is equipped with a first electric telescopic rod 303. The first electric telescopic rod 303 is fixedly mounted on the central support plate 301 via a fixing seat 302. The first electric telescopic rod 303 is a dual-axis electric push rod. The two push rod ends of the first electric telescopic rod 303 are fixedly connected to the upper support plate 304 and the lower support plate 306 respectively. The upper and lower sides of the central support plate 301 are respectively fixedly connected to one end of two parallel guide rods 305. The upper end of the upper guide rod 305 is slidably connected to the first guide sliding hole opened at the corresponding position of the upper support plate 304, and the lower end of the lower guide rod 305 is slidably connected to the second guide sliding hole opened at the corresponding position of the lower support plate 306.

[0045] See instruction manual attached Figure 3 and 8As shown, a filter screen 601 is installed in the middle of the interior of the filter pipe 6, and a filter frame plate 604 is installed on the outer side of the filter screen 601. A track groove 602 for sliding connection of the filter frame plate 604 is opened on the inner side wall of the filter pipe 6. One side of the track groove 602 is open, and an end plate 603 is installed on one side of the filter frame plate 604. The interior of the filter pipe 6 is hollow and open at both ends. An insert 605 is provided at both ends of the filter pipe 6 for respectively engaging with the waste liquid pipe 1 and the lower through pipe structure 4. A sealing gasket 606 is provided on the side of the filter pipe 6 near the insert 605. Through the above specific structural design, when the time interval between the liquid level sensor 805 of the liquid level detection component 8 detecting the liquid level inside the filter pipe 6 reaching a certain height becomes shorter and shorter and reaches a certain time, it proves that the filter screen 601 is becoming more and more clogged and needs to be cleaned. At this time, the filter frame plate 604 can be pulled out from the track groove 602 for replacement and cleaning.

[0046] To complement the aforementioned filter pipe 6, the lower pipe structure 4 includes a slag discharge pipe 401. A drain pipe 402 is vertically connected to one side of the middle of the slag discharge pipe 401. The slag discharge pipe 401 and the drain pipe 402 are integrally formed in a T-shape. A baffle 403 is installed on the inner side of the drain pipe 402 near the slag discharge pipe 401. Through the above specific structural design, the slag discharge and drain pipe functions can be switched when the lower pipe structure 4 is rotated by the pipe support assembly 3.

[0047] The waste liquid tank 5 includes a tank body 501. Slag collection chambers 502 are located on both sides of the tank body 501. A V-shaped screen 506 is installed on the upper side of each slag collection chamber 502, with the pointed end of the screen 506 facing upwards. A support net 505 is installed in the lower part of each slag collection chamber 502 to divide its bottom into a liquid accumulation cavity 503. A slag outlet is located on the upper side of the slag collection chamber 502 near the support net 505, and a rotating cover 504 is installed at the slag outlet. Through this specific structural design, during slag discharge, the liquid and waste residue can be separated by the screen 506. The liquid falls into the tank body 501, and the waste residue falls into the slag collection chamber 502. The waste residue in the slag collection chamber 502 can be cleaned out by opening the rotating cover 504.

[0048] See instruction manual attached Figure 4 and 7As shown, the liquid level detection assembly 8 includes a seat 801, one end of which is connected to the waste liquid pipe 1. A telescopic groove 802 is provided inside the seat 801. One end of the telescopic groove 802 is open and communicates with the inside of the waste liquid pipe 1. One end of the telescopic groove 802 is closed, and a second electric telescopic rod 803 is fixedly installed inside the closed end. A piston 804 is fixedly connected to the push rod head of the second electric telescopic rod 803. The piston 804 is slidably installed inside the telescopic groove 802. A liquid level sensor 805 is installed on the piston 804. The output end of the liquid level sensor 805 is electrically connected to the input end of the digital display control panel 7. The output end of the digital display control panel 7 is electrically connected to the input end of the second electric telescopic rod 803. Through the above-described structural design, the liquid level sensor 805 can detect the liquid level in the filter pipe 6. When the liquid level in the filter pipe 6 reaches a certain value, it is fed back to the digital display control panel 7 to control the on / off of the draining device, thereby controlling the disconnection of the waste liquid pipe 1. This achieves automatic separation and cleaning of impurities in the filter pipe 6. When the second electric telescopic rod 803 drives the liquid level sensor 805 to retract into the telescopic slide 802, it can avoid interference with the cleaning of the cleaning pipe assembly 2.

[0049] Working principle:

[0050] During use, waste liquid is discharged from waste liquid pipe 1, passes through filter pipe 6 and lower pipe structure 4 in sequence, and enters waste liquid pool 5. During this process, the waste liquid is filtered by filter screen 601 inside filter pipe 6 to achieve solid-liquid separation. Solid impurities are retained on filter screen 601, and the remaining chemical waste liquid falls into waste liquid pool 5 through lower pipe structure 4. When solid impurities accumulate to a certain height on filter screen 601, the fixed impurities will block the mesh on filter screen 601, preventing the waste liquid from flowing downwards and causing it to rise to a certain height in filter pipe 6. At this time, the liquid level sensor 805 of liquid level detection component 8 can detect the liquid level in filter pipe 6 and transmit the detected electrical signal to digital display control panel 7. Digital display control panel 7 controls the drain on / off device connected to waste liquid pipe 1 to stop draining. The two push rods of the first electric telescopic rod 303 on pipe support component 3 extend, thereby driving waste liquid pipe 1, filter pipe 6 and lower pipe structure 4 to separate from each other. First, the third Motor 309 drives the lower pipe structure 4 to rotate 90 degrees up and down, making the slag discharge pipe 401 vertical and the liquid discharge pipe 402 horizontal. Then, the second motor 308 drives the filter pipe 6 to rotate 180 degrees up and down. At this time, the solid impurities on the filter screen 601 separate from the filter screen 601 and fall into the slag discharge pipe 401. Together with the cleaning pipe assembly 2, the impurities on the filter screen 601 are cleaned and then enter the waste liquid tank 5 onto the screening screen 506. The material slides upwards and downwards into the slag collection chamber 502. The third motor 309 drives the lower pipe structure 4 to rotate 90 degrees, making the slag discharge pipe 401 horizontal and the liquid discharge pipe 402 vertical with its opening facing upwards. At this time, the two push rods of the first electric telescopic rod 303 on the pipe support assembly 3 retract, thereby driving the waste liquid pipe 1, the filter pipe 6 and the lower pipe structure 4 to move closer to each other and connect. The liquid discharge switch on the waste liquid pipe 1 is opened again to continue the solid-liquid separation treatment of the chemical waste liquid.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
