Description

Technical Field

[0001] This utility model belongs to the field of chemical wastewater treatment, and specifically relates to a filtration device for chemical wastewater. Background Technology

[0002] In chemical production processes, wastewater often contains a large amount of solid impurities, suspended solids and colloidal substances, which need to be filtered.

[0003] Chinese patent CN211562087U discloses an environmentally friendly filtration device for chemical wastewater. The device includes a main body, a cover plate connected to an inlet pipe at the top of the main body, and a drain pipe at the bottom. The main body houses a filtration mechanism. A vibration mechanism is located on the left side of the main body to drive the filtration mechanism, and an impurity storage tank is located on the right side to collect impurities. This invention effectively solves the problem of solid impurities hindering subsequent purification of chemical wastewater by separating solid impurities from the wastewater through the filtration mechanism and storing them in the impurity storage tank.

[0004] However, the aforementioned filtration device lacks a blocking mechanism, and the opening leading to the impurity storage tank is relatively large. During the filtration process, a large amount of chemical wastewater flows into the impurity storage tank, resulting in a large amount of chemical wastewater residue that cannot flow out of the device for the next processing procedure, which is detrimental to its use. Utility Model Content

[0005] The purpose of this utility model is to provide a filtration device for chemical wastewater, so as to solve the problem mentioned in the background art that the traditional filtration device does not have a blocking mechanism, and a large amount of chemical wastewater will flow into the impurity storage tank during the filtration process, resulting in a large amount of chemical wastewater residue.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A filtration device for chemical wastewater includes a filtration mechanism and a swing shielding mechanism. The filtration mechanism includes a housing, within which a filter screen is movably disposed. An opening is provided on one side of the housing surrounding the filter screen, and a storage box is provided on another side of the housing surrounding the opening. The swing shielding mechanism includes a protective shell disposed on the other side of the housing. The front end of the filter screen penetrates the housing and is movably connected to the protective shell via a rotating shaft. A counterweight is provided at the bottom of the filter screen on the other side of the rotating shaft. A movable groove is provided on the other side of the housing surrounding the filter screen. A baffle is movably disposed at the bottom of the front end of the filter screen, and the baffle is telescopically connected to the housing.

[0008] Preferably, the top of the housing is provided with a sewage inlet, and the bottom of the housing is provided with a sewage outlet.

[0009] Preferably, a shaft is movably provided at the top of the baffle, and a slide rail is provided at the bottom of the filter screen, with the slide rail slidably connected to the shaft.

[0010] Preferably, a filter screen is provided between the bottom of the storage box and the shell.

[0011] Preferably, a sleeve is provided on the top and bottom shells of the movable groove, and a sealing plate is movably arranged inside the sleeve by a spring. The front ends of the two sealing plates penetrate the sleeve and contact the top and bottom of the filter screen.

[0012] Preferably, the filter screen and the counterweight are connected by a connecting rope.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention achieves automatic sliding and centralized collection of impurities by tilting and swinging the filter screen, reducing manual intervention. The vibration generated when the filter screen swings accelerates the removal of impurities, avoids clogging, and ensures continuous filtration. The baffle mechanism automatically closes the opening during the filtration process to prevent excessive wastewater residue in the storage box. Relying on gravity and mechanical linkage, it does not require external power equipment, reducing manufacturing costs and failure rate. Attached Figure Description

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] As attached Figure 1 and attached Figure 2 As shown:

[0025] Example 1: This example provides a filtration device for chemical wastewater, including a filtration mechanism 1 and a swing shielding mechanism 2. The filtration mechanism 1 includes a housing 101, a filter screen 102 is movably disposed inside the housing 101, an opening 103 is provided on one side of the housing 101 surrounding the filter screen 102, and a storage box 104 is provided on one side of the housing 101 surrounding the opening 103. The swing shielding mechanism 2 includes a protective shell 201 disposed on the other side of the housing 101. The front end of the filter screen 102 penetrates the housing 101 and is movably connected to the protective shell 201 through a rotating shaft 202. A counterweight 204 is provided at the bottom of the filter screen 102 on the other side of the rotating shaft 202. A movable groove 207 is provided on the other side of the housing 101 surrounding the filter screen 102. A baffle 205 is movably disposed at the bottom of the front end of the filter screen 102 and is telescopically connected to the housing 101.

[0026] During operation, wastewater enters through the top of the housing 101, passes through the filter screen 102, and flows out from the bottom of the housing 101. During the process, the chemical wastewater is filtered through the filter screen 102. In the initial state, the counterweight 204 will pull the front end of the filter screen 102 downward by its own weight, causing it to rotate around the pivot 202. At this time, the rear end of the filter screen 102 will tilt upward until it contacts the top of the opening 103 and returns to a horizontal state. During this process, an upward force is applied to the baffle 205, causing it to move upward and extend within the housing 101, blocking the gap between the bottom of the filter screen 102 and the housing 101, and blocking the opening 103. Thus, the opening 103 is sealed during the filtration process, preventing some wastewater from entering the storage box 104 through the opening 103.

[0027] When there are many impurities filtered on filter screen 102, the weight of the rear end of filter screen 102 will be greater than the weight of counterweight 204, causing the rear end of filter screen 102 to rotate downward around the pivot 202 and return to the tilted state. At this time, the impurities on filter screen 102 will slide into the storage box 104 for centralized storage, completing the self-cleaning of impurities on filter screen 102. Furthermore, the swinging and collision will generate a certain vibration, increasing the impurity removal speed. After the removed impurities reach the required weight reduction, filter screen 102 will automatically reset and continue the blocking and filtering work.

[0028] Specifically, a sewage inlet 105 is provided at the top of the housing 101, and a sewage outlet 106 is provided at the bottom of the housing 101.

[0029] As can be seen from the above, by connecting the shell 101 to the chemical wastewater inlet pipe through the wastewater inlet 105 and connecting the shell 101 to the chemical wastewater outlet pipe through the wastewater outlet 106, the device can be directly connected in series with the chemical wastewater pipeline, thus achieving filtration during the chemical wastewater transportation process.

[0030] As attached Figure 3 As shown:

[0031] Example 2: This example is basically the same as the previous example, except that the top of the baffle 205 is movably provided with a shaft 2052, and the bottom of the filter screen 102 is provided with a slide rail 2051, which is slidably connected to the shaft 2052.

[0032] When filter screen 102 swings, shaft 2052 will rotate on baffle 205 and slide on slide rail 2051, thereby converting the rotation of filter screen 102 into the vertical up and down movement of baffle 205.

[0033] As attached Figure 1 and attached Figure 2 As shown:

[0034] Specifically, a filter screen 206 is provided between the bottom of the storage box 104 and the housing 101.

[0035] As attached Figure 4 As shown:

[0036] Specifically, a housing 2072 is provided on the top and bottom shells 101 of the movable groove 207. A sealing plate 2071 is movably provided inside the housing 2072 by a spring 2073. The front ends of the two sealing plates 2071 penetrate the housing 2072 and contact the top and bottom of the filter screen 102.

[0037] Specifically, the filter screen 102 and the counterweight 204 are connected by a connecting rope 203.

[0038] As can be seen from the above, during the filtration process, some wastewater may enter the storage box 104. The bottom of the storage box 104 is inclined, and the residual wastewater will flow to the bottom of the storage box 104 and then re-enter the shell 101 through the filter screen 206, which greatly reduces the amount of wastewater residue.

[0039] When filter screen 102 swings, it moves away from or towards the bottom or top sealing plate 2071. When filter screen 102 moves away from sealing plate 2071, spring 2073 pushes sealing plate 2071 with its own elasticity, keeping it in contact with filter screen 102. When filter screen 102 moves towards sealing plate 2071, spring 2073 contracts and uses reaction force to push sealing plate 2071, keeping it in contact with filter screen 102. This ensures that the movable groove 207 is always blocked, preventing sewage impurities from flowing into the protective shell 201 through the movable groove 207, and further preventing sewage residue.
