Description

Technical Field

[0001] This utility model relates to the field of waste liquid purification technology, specifically a modular chemical waste acid waste liquid separation and purification equipment. Background Technology

[0002] With increasing environmental awareness and growing demand for resource recycling, the chemical industry is facing increasingly stringent environmental regulations and challenges in resource utilization efficiency. Waste acid and waste liquid contain a large amount of organic matter, and direct discharge will not only cause environmental pollution but also waste resources. Therefore, developing a high-efficiency and environmentally friendly waste acid and waste liquid separation and purification equipment has become an urgent need for the industry.

[0003] Most separation and purification equipment currently operates on the principle of filtering out a large portion of impurities through a filtration device, followed by separating the organic matter through stirring and centrifugation. However, after long-term use, the surface pores of the filtration device become clogged, which can affect the filtration effect if not cleaned in time. Furthermore, a single filtration device has a relatively low filtration efficiency. Summary of the Invention

[0004] The purpose of this utility model is to provide a modular chemical waste acid and waste liquid separation and purification equipment to solve the problems mentioned in the background art, such as the clogging of the surface filter holes of the filter device after long-term use, which will affect the filtration effect if not cleaned in time, and the low filtration effect of a single filter device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model discloses a modular chemical waste acid and waste liquid separation and purification device, including a box body, an inlet on the top plate of the box body, an outlet on the bottom plate of the box body, and a filter cleaning component, a waste liquid neutralization component and a filter collection component arranged sequentially from top to bottom in the inner cavity of the box body.

[0007] The filtration and cleaning assembly includes a filter support, a first filter installed in the middle of the filter support, a scraper connected above the filter support via a slide rail, and a telescopic cylinder for driving the scraper to move along the track.

[0008] The waste liquid neutralization assembly includes a neutralization tank, a stirring mechanism installed at the bottom of the inner cavity of the neutralization tank, an alkaline substance inlet pipe introduced from outside the tank to the upper end of the neutralization tank, and an outlet pipe with a control valve installed at the bottom of the neutralization tank.

[0009] The filter collection assembly includes a filter collection box and a second filter screen; the filter collection box is a box structure with an open top, and the inner cavity of the filter collection box is divided into two chambers, front and rear, by a partition. The bottom of the rear chamber is open and the second filter screen is installed thereon, and the front chamber serves as a waste collection bin.

[0010] An impurity separation channel is provided between the right side of the filter cleaning component and the waste liquid neutralization component and the inner wall of the box, and the lower part of the impurity separation channel is directly opposite the waste collection bin of the filter collection component.

[0011] The lower side wall of the box has a collection box outlet. The filter collection box is slidably connected to the box via rollers, and the filter collection box can be taken out and put in through the collection box outlet.

[0012] The filter collection box is provided with a handle on the outer side wall for easy removal and placement.

[0013] Work process

[0014] Alkaline substances are injected into the neutralization tank through the alkaline substance inlet pipe. Waste acid and waste liquid enter the tank through the inlet, pass through the first filter screen of the filtration and cleaning assembly, and then enter the neutralization tank. The stirring mechanism is activated to ensure that the waste acid and waste liquid are fully neutralized and reacted with the alkaline substances. After the reaction is completed, the control valve on the outlet pipe is opened, allowing the reaction liquid to flow downwards through the second filter screen of the filtration and collection assembly and then out of the outlet of the tank. When impurities are present on the first filter screen, the scraper is driven to move to the right along the track by the telescopic cylinder, pushing the impurities on the first filter screen to the right into the impurity separation channel and falling into the waste collection bin. When too many impurities accumulate on the second filter screen or the waste collection bin in the filtration and collection assembly, the filter collection bin is removed from the collection bin outlet, the impurities are emptied, and then the filter collection bin is put back in for further separation and purification of waste acid and waste liquid.

[0015] Beneficial effects

[0016] The separation and purification equipment of this utility model can reliably separate and purify chemical waste acid and waste liquid. The equipment has a simple structure and is easy to use, and solves the problem of surface filter pores clogging after long-term use of filter devices. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be further described in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 As shown, the present invention provides a modular chemical waste acid and waste liquid separation and purification device, including a box body 1, an inlet 2 set on the top plate of the box body 1, an outlet 5 set on the bottom plate of the box body 1, and a filter cleaning component 6, a waste liquid neutralization component and a filter collection component 4 arranged sequentially from top to bottom in the inner cavity of the box body 1.

[0024] like Figure 2 As shown, the filter cleaning assembly 6 includes a filter support 14, a first filter 15 installed in the middle of the filter support 14, a scraper 13 connected above the filter support 14 via a slide rail, and a telescopic cylinder 11 for driving the scraper 13 to move along the rail.

[0025] The waste liquid neutralization assembly includes a neutralization tank 7, a stirring mechanism 8 installed at the bottom of the inner cavity of the neutralization tank 7, an alkaline substance inlet pipe 3 introduced from outside the box 1 to the upper end of the neutralization tank 7, and an outlet pipe 10 with a control valve set at the bottom of the neutralization tank 7.

[0026] like Figure 3 As shown, the filter collection assembly 4 includes a filter collection box 16 and a second filter screen 20; the filter collection box 16 is a box structure with an open top, and the inner cavity of the filter collection box 16 is divided into two chambers, front and rear, by a partition 19. The bottom of the rear chamber is open and the second filter screen 20 is installed thereon, and the front chamber serves as a waste collection bin 21.

[0027] An impurity separation channel 9 is provided between the right side of the filter cleaning component 6 and the waste liquid neutralization component and the inner wall of the box 1. The impurity separation channel 9 is directly below the waste collection bin 21 of the filter collection component 4.

[0028] The lower side wall of the box 1 has a collection box outlet. The filter collection box 16 is slidably connected to the box 1 via rollers 17. The filter collection box 16 can be taken out and put in through the collection box outlet.

[0029] The filter collection box 16 is provided with a handle 18 on its outer side wall for easy access to the filter collection box 16.

[0030] Work process

[0031] Alkaline substances are injected into the neutralization tank 7 through the alkaline substance inlet pipe 3. Waste acid and waste liquid enter the tank 1 through the inlet 2, and after being filtered by the first filter screen 15 of the filtration and cleaning assembly 6, they enter the neutralization tank 7. The stirring mechanism 8 is turned on to allow the waste acid and waste liquid to fully neutralize and react with the alkaline substances. After the reaction is completed, the control valve on the outlet pipe 10 is turned on, allowing the reaction liquid to flow downward through the second filter screen 20 of the filtration and collection assembly 4 and then out of the outlet 5 of the tank 1. When impurities are present on the first filter screen 15, the scraper 13 is driven to move to the right along the track by the telescopic cylinder 11, so that the impurities on the first filter screen 15 are pushed to the right to the impurity separation channel 9 and fall into the waste collection bin 21. When too many impurities accumulate on the second filter screen 20 or the waste collection bin 21 in the filter collection assembly 4, the filter collection box 16 is taken out from the collection box outlet and the impurities are poured out. Then, it is put back into the filter collection box 16, so that the separation and purification of waste acid and waste liquid can be carried out again.
