Description

TECHNICAL FIELD

[0001] The present application relates to the field of chemical waste liquid treatment, and particularly relates to a harmless treatment equipment for waste liquid in chemical production. BACKGROUND

[0002] In the chemical production process, a large amount of waste liquid is generated. The chemical waste liquid has complex water quality and contains various solid and liquid impurities. The waste liquid needs to be treated in various ways and then discharged after reaching the standard. In the waste liquid, the catalyst can accelerate the degradation of organic matter in the waste liquid.

[0003] For example, a chemical organic wastewater purification treatment device is disclosed in Chinese Patent No. CN119370927A. The device is designed to deform the net bag to make the catalyst contact with the wastewater more fully. However, the device has the following defects:

[0004] 1. Since the container containing the catalyst moves in a circular trajectory in the waste liquid, only the waste liquid near the circular trajectory can fully contact the catalyst, and the waste liquid in other areas is not catalyzed sufficiently.

[0005] 2. The impurities in the waste liquid are easily attached to the container containing the catalyst, so that the catalyst cannot fully contact the waste liquid. SUMMARY

[0006] In order to overcome the shortcomings of the existing chemical waste liquid treatment equipment that the catalyst cannot fully contact the waste liquid, the present application provides a harmless treatment equipment for waste liquid in chemical production.

[0007] The technical implementation scheme of the present application is as follows: a harmless treatment equipment for waste liquid in chemical production, comprising a treatment tank and an electrically-driven stirring shaft; an electrically-driven stirring shaft is installed in the middle of the treatment tank; an annular flow channel is formed between the inside of the treatment tank and the electrically-driven stirring shaft; further comprising a mounting bracket, a telescopic driving member, a mounting plate and a loading cylinder; the mounting bracket is arranged on the side of the treatment tank; the telescopic driving member is installed on the mounting bracket; the telescopic end of the telescopic driving member is connected with the loading cylinder through the mounting plate, and the loading cylinder is used for loading the catalyst; the lower half of the loading cylinder is a mesh part; the mesh part of the loading cylinder is located at the annular flow channel.

[0008] Further, a rotary driving member is installed on the mounting plate; the rotary end of the rotary driving member is connected with the loading cylinder.

[0009] Further, a connecting rod is installed on the mounting bracket; a mesh cylinder for loading the catalyst is connected to the lower end of the connecting rod through a connecting seat; the connecting rod is rotationally connected with the connecting seat; and the mesh cylinder is located inside the mesh part.

[0010] Further, the bottom plate of the loading cylinder is provided with a through groove, which is matched with the shape of the mesh cylinder.

[0011] Further, the height of the annular flow channel is equal to the height of the mesh hole part plus the height of the mesh cylinder.

[0012] Further, the connecting seat is a tapered surface structure with a narrow upper part and a wide lower part.

[0013] Further, the connecting rod is provided with two vertical rows of stirring rods arranged symmetrically.

[0014] Further, the mesh cylinder is flat and long.

[0015] Further, the vertical span of each vertical row of stirring rods is the same as the height of the mesh hole part.

[0016] Further, the connecting seat and the mesh cylinder are detachably connected.

[0017] The present application has the following advantages: the present application enables the stirred waste liquid to flow orderly along the annular flow channel, and the loading cylinder containing the catalyst and the mesh cylinder are located at the annular flow channel, so that the waste liquid can orderly flow through the loading cylinder containing the catalyst and the mesh cylinder, and the waste liquid can fully contact with the catalyst. Compared with the prior art in which the container containing the catalyst moves in a circular trajectory in the waste liquid, only the waste liquid near the circular trajectory can fully contact with the catalyst, and the waste liquid in other areas is not fully catalyzed. The present application adopts the way of making the waste liquid orderly flow through the catalyst, so that all the waste liquid can contact with the catalyst.

[0018] The present application drives the loading cylinder to rotate by the rotating driving member. Since the waste liquid flows orderly along the annular flow channel, the part of the loading cylinder facing the direction of the waste liquid flow is always changing during the rotation, and the outer surface of the loading cylinder is a circular arc surface, so the impurities in the waste liquid can be washed away with the flow of the waste liquid and cannot stably adhere to the outer surface of the loading cylinder, thereby reducing the adhesion of impurities in the waste liquid on the loading cylinder.

Detailed Implementation

[0025] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] Example 1: A waste liquid harmless treatment device in chemical safety production, such as... Figures 1-5 As shown, it includes a processing tank 1 and an electrically driven agitator 2; the electrically driven agitator 2 consists of an agitator shaft and a motor that drives the agitator shaft to rotate, and the motor is mounted on a horizontal plate at the upper end of the processing tank 1; an annular flow channel 101 is formed between the interior of the processing tank 1 and the electrically driven agitator 2; it also includes a mounting frame 3, a telescopic drive component 4, a mounting plate 5, and a loading cylinder 6; the mounting frame 3 is disposed on the side of the processing tank 1; the telescopic drive component 4 is mounted on the upper end of the mounting frame 3, and the telescopic drive component 4 is an electrically driven push rod; the telescopic end of the telescopic drive component 4 is connected to the loading cylinder 6 through the mounting plate 5; the lower half of the loading cylinder 6 is a mesh section 61.

[0027] A rotary drive component 7, which is a DD motor, is mounted on the mounting plate 5; the rotating end of the rotary drive component 7 is connected to the loading cylinder 6.

[0028] A connecting rod 8 is installed on the upper end of the mounting bracket 3; the lower end of the connecting rod 8 is connected to a mesh tube 11 through a connecting seat 10; the connecting rod 8 is rotatably connected to the connecting seat 10; the mesh tube 11 is located inside the mesh portion 61, and the connecting rod 8 passes through the central gap of the rotating drive component 7.

[0029] The bottom plate of the loading cylinder 6 has a through groove 62, which is adapted to the shape of the mesh cylinder 11.

[0030] The height of the annular flow channel 101 is equal to the sum of the height of the mesh portion 61 and the height of the mesh cylinder 11.

[0031] The connecting seat 10 has a conical structure that is narrow at the top and wide at the bottom. When the mesh cylinder 11 and the connecting seat 10 move upward, the conical surface of the connecting seat 10 pushes the catalyst in the loading cylinder 6 apart.

[0032] In this embodiment, granular catalyst is pre-loaded into the loading cylinder 6 and the mesh cylinder 11, with the amount of catalyst in the loading cylinder 6 just filling the height of the mesh portion 61. Waste liquid is injected into the treatment tank 1, and the electric drive stirring shaft 2 is started to stir the waste liquid in the treatment tank 1. Since the electric drive stirring shaft 2 forms an annular flow channel 101 with the inner wall of the treatment tank 1, the stirred waste liquid flows orderly along the annular flow channel 101. At this time, the loading cylinder 6 and the mesh cylinder 11 containing the catalyst are located at the annular flow channel 101, so that the waste liquid can flow through the loading cylinder 6 and the mesh cylinder 11 containing the catalyst in an orderly manner, so that the waste liquid can fully contact the catalyst. Compared with the prior art, which uses a container containing the catalyst to make a circular trajectory in the waste liquid, only the waste liquid near the circular trajectory can fully contact the catalyst, resulting in insufficient catalysis of waste liquid in other areas, the present invention uses a method of allowing the waste liquid to flow through the catalyst in an orderly manner, ensuring that all waste liquid can contact the catalyst.

[0033] Furthermore, in order to reduce the adhesion of impurities in the waste liquid to the loading cylinder 6, a rotary drive 7 is added to drive the loading cylinder 6 to rotate. Since the waste liquid flows orderly along the annular flow channel 101, and the part of the loading cylinder 6 facing the direction of waste liquid flow is constantly changing during the rotation, and the outer surface of the loading cylinder 6 is an arc surface, the impurities in the waste liquid will be washed away with the flow of waste liquid and cannot stably adhere to the outer surface of the loading cylinder 6, thereby reducing the adhesion of impurities in the waste liquid to the loading cylinder 6.

[0034] Furthermore, to address the issue of insufficient contact between the internal catalyst and the waste liquid, a double-layer loading structure consisting of a loading cylinder 6 and a mesh cylinder 11 was designed. After the waste liquid flows along the annular flow channel 101 for a period of time, the telescopic drive component 4 is controlled to move the mounting plate 5 and the loading cylinder 6 upwards, causing the mesh portion 61 to move upwards, while the height of the mesh cylinder 11 remains unchanged, allowing the mesh cylinder 11 to pass through the through groove 62 and be exposed. Figure 5 As shown, the catalyst loaded inside the mesh cylinder 11 is exposed, allowing the catalyst located inside to fully contact the waste liquid.

[0035] Further, considering that the amount of waste liquid to be treated will be different, when the height of the waste liquid in the treatment tank 1 does not exceed the height of the mesh hole part 61, the initial state of the mesh cylinder 11 is inside the mesh hole part 61, and when the height of the waste liquid in the treatment tank 1 exceeds the height of the mesh hole part 61, the mounting plate 5 and the loading cylinder 6 are driven upward by the telescopic drive 4 to move the mesh cylinder 11 to pass through the through groove 62 to expose the mesh cylinder 11, so that the length of the mesh cylinder 11 exposed from the mesh hole part 61 matches the overall height of the mesh hole part 61 superimposed on the inside of the mesh hole part 61 and the height of the waste liquid in the treatment tank 1, so that the exposure of the mesh cylinder 11 is controlled to adjust the vertical distribution height of the catalyst and adapt to the amount of waste liquid to be treated, so that the utilization rate of the catalyst is maximized.

[0036] Wherein, the mesh cylinder 11 moves up and down in the through groove 62, and the mesh cylinder 11 rotates together with the loading cylinder 6, when the mesh cylinder 11 moves upward in the through groove 62, the edge of the through groove 62 will scrape the outer surface of the mesh cylinder 11, and the impurities attached to the outer surface of the mesh cylinder 11 will be scraped off, avoiding the impurities entering the loading cylinder 6, and reducing the subsequent maintenance workload.

[0037] Example 2: Based on example 1, as shown in Figures 1-5 The lower outer ring surface of the connecting rod 8 is provided with two vertical rows of stirring rods 9 arranged symmetrically.

[0038] The mesh cylinder 11 is flat and long strip-shaped.

[0039] The vertical span of each vertical row of stirring rods 9 is the same as the height of the mesh hole part 61.

[0040] The connecting seat 10 and the mesh cylinder 11 are detachably connected, and the worker can detach the mesh cylinder 11 from the connecting seat 10 to replace the catalyst in the mesh cylinder 11.

[0041] In this embodiment, when the height of the waste liquid in the treatment tank 1 exceeds the height of the mesh hole part 61, the mesh cylinder 11 will pass through the through groove 62 to expose to adapt to the height of the waste liquid, at this time, by adding the stirring rod 9, when the mesh cylinder 11 passes through the through groove 62 to expose, the stirring rod 9 can reach the inside position of the mesh hole part 61, so that the catalyst in the loading cylinder 6 can be stirred by the stirring rod 9 during the rotation process driven by the rotating drive 7, so as to increase the contact between the catalyst in the loading cylinder 6 and the waste liquid.

[0042] Further, the mesh cylinder 11 is designed to be flat and long strip-shaped, so that the catalyst in the mesh cylinder 11 can be distributed in a flat shape, which not only reduces the thickness of the catalyst in the mesh cylinder 11, but also makes the catalyst spread out and fully contact with the waste liquid, and makes the span of the distribution position of the catalyst in the mesh cylinder 11 larger, so as to maximize the full contact with the waste liquid flowing in the annular flow passage 101.

[0043] Finally, it should be noted that the above examples are merely intended to illustrate the technical solutions of the present application and not to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present application.
