Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an industrial wastewater treatment filtration device that facilitates filter screen replacement. Background Technology

[0002] Industrial wastewater treatment filtration devices are the core equipment in wastewater treatment systems. They are mainly used to remove pollutants such as suspended solids, colloids, organic matter, heavy metals, and microorganisms from wastewater to ensure that the water quality meets discharge standards or reuse requirements.

[0003] Installing a primary filter in the inlet pipe of an industrial wastewater treatment filtration device can significantly improve equipment stability, treatment efficiency, and water quality, while reducing long-term operation and maintenance costs.

[0004] Pre-filters are typically fixed inside the inlet pipe, which necessitates the disassembly of multiple components, making the process complex, time-consuming, and inconvenient for users to inspect and replace later. Therefore, there is an urgent need for an industrial wastewater treatment filtration device that facilitates the replacement of pre-filters. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an industrial wastewater treatment filtration device that facilitates filter screen replacement.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An industrial wastewater treatment filtration device with easy-to-replace filter screen includes a wastewater treatment filtration device body. An inlet pipe is fixedly installed on the wastewater treatment filtration device body. A primary filter screen is installed in the inlet pipe through an installation component. An installation plate is fixedly installed on both sides of the inlet pipe at the installation component. Movable components are movably installed on both sides inside the installation component. Multiple locking posts are fixedly installed on the outer side of each movable component. The corresponding locking posts on the installation plate are adapted to have locking cavities. A pressing component for locking the installation component is vertically movably installed inside the installation component.

[0008] In addition, a preferred structure is that the top of the water inlet pipe has a downward-facing installation cavity, and installation plates are fixedly installed on both sides of the installation cavity, and the installation components are adapted to the installation cavity.

[0009] In addition, a preferred structure is that a primary filter screen is fixedly installed at the bottom of the mounting component corresponding to the inner wall of the water inlet pipe, and a movable cavity is opened inside the mounting component.

[0010] In addition, a preferred structure is that a partition is fixedly provided in the middle of the movable cavity, the movable parts are adapted to move on both sides of the partition, and through holes are adapted to be opened on the corresponding locking posts of the mounting parts.

[0011] Furthermore, in a preferred configuration, multiple guide posts are fixedly installed upwards at the top of the partition within the active cavity, and the extruder is guided to move by the guide posts.

[0012] Furthermore, in a preferred configuration, multiple springs are mounted downwards on the top of the active cavity, and the other end of each spring is connected to the extrusion member.

[0013] The beneficial effects of this utility model are as follows: the wastewater treatment filtration device body can achieve the filtration treatment of industrial wastewater. Through the mutual locking between the clamping column and the clamping cavity, and with the locking of the extrusion part, the primary filter screen can be fixedly installed. This method of disassembling and assembling the primary filter screen is simple and convenient, making it easy for users to inspect and replace the primary filter screen in the later stage.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-8 An industrial wastewater treatment filtration device with easy-to-replace filter screen includes a wastewater treatment filtration device body 1. An inlet pipe 2 is fixedly installed on the wastewater treatment filtration device body 1. A primary filter screen 40 is installed inside the inlet pipe 2 via a mounting component 4. Mounting plates 3 are fixedly installed on both sides of the inlet pipe 2 at the mounting component 4. Movable components 5 are movably installed on both sides inside the mounting component 4. Multiple locking posts 51 are fixedly installed on the outer side of each movable component 5. The mounting plates 3 have corresponding locking cavities 31. A pressing component 6 for locking the mounting component 4 is vertically movably installed inside the mounting component 4.

[0025] The water inlet pipe 2 has a downward-facing mounting cavity 21 at its top. Mounting plates 3 are fixedly installed on both sides of the mounting cavity 21, and the mounting component 4 is adapted to the mounting cavity 21. Sealing elements are provided on the inner wall of the mounting cavity 21 and on the mounting plate 3 to ensure the airtightness of the inside of the water inlet pipe 2.

[0026] The bottom of the mounting component 4 is fitted with a primary filter screen 40 that is fixedly installed on the inner wall of the water inlet pipe 2, and the mounting component 4 has an open movable cavity 41 inside.

[0027] The movable cavity 41 has a partition 42 fixedly installed in the middle. The movable component 5 is adapted to move on both sides of the partition 42, and the mounting component 4 has through holes 45 corresponding to the locking posts 51. The locking posts 51 can pass through the through holes 45 and be locked into the locking cavity 31. The bottom of the movable component 5 is fixedly provided with multiple sliders, and the movable cavity 41 has corresponding sliding grooves for the sliders. This not only improves the stability of the movable component 5 during movement, but also prevents the movable component 5 from falling out of the movable cavity 41.

[0028] Within the movable cavity 41, multiple guide pillars 43 are fixedly installed upwards at the top of the partition 42, and the extrusion member 6 is guided to move by the guide pillars 43. The guide pillars 43 improve the stability of the extrusion member 6 during the movement process.

[0029] Multiple springs 44 are mounted downwards on the top of the movable cavity 41, and the other end of each spring 44 is connected to the pressing member 6. The springs 44 allow the pressing member 6 to be stably pressed downwards, thus stably locking the movable members 5 on both sides.

[0030] In this embodiment, industrial wastewater can be filtered through the wastewater treatment filtration device body 1. The wastewater treatment filtration device body 1 uses a porous medium to separate the solid and liquid components of the suspension. It utilizes external forces (such as pressure difference, centrifugal force, etc.) to force the wastewater through the porous medium. The liquid passes through the medium's pores to become filtrate, while solid particles are trapped on the medium's surface or in its internal pores, forming a filter cake or filter residue, thereby achieving purification. It is worth noting that the specific depth filtration method and filtration structure of the wastewater treatment filtration device body 1 are existing technologies and are not related to the technical problem of easily replacing the primary filter screen 40 that needs to be addressed in this technical solution; therefore, they will not be elaborated upon further.

[0031] Furthermore, when installing the primary filter 40, simply insert the mounting part 4 into the mounting cavity 21 inside the water inlet pipe 2 to install the primary filter 40 in the designated position. At this time, the through holes 45 on the mounting part 4 are all aligned with the locking cavity 31 on the mounting plate 3.

[0032] The user then simply moves the movable parts 5 on both sides outwards, causing the locking pins 51 on the movable parts 5 to pass through the through holes 45 and engage in the locking cavity 31. When both movable parts 5 are moved to their outermost positions, the pressing member 6 will automatically fall down due to its own weight and the elastic force of the spring 44. This fixes the pressing member 6 to the outside of the movable part 5, thus securing the movable part 5 and allowing the locking pins 51 to be securely engaged in the locking cavity 31, thereby achieving the fixed installation of the mounting member 4 and the primary filter 40.

[0033] Furthermore, when the user needs to disassemble the pre-filter 40, simply move the pressing member 6 upwards. This will compress the spring 44, and the pressing member 6 will no longer be stuck on the outside of the movable member 5. Then, press the movable members 5 on both sides towards the partition 42, thereby causing the locking post 51 to retract into the movable cavity 41 through the movable member 5, thus releasing the mutual jamming between the locking post 51 and the locking cavity 31. Finally, simply pull the mounting member 4 upwards to remove the pre-filter 40.

[0034] In this utility model, the wastewater treatment filter body 1 can achieve the filtration treatment of industrial wastewater. The primary filter screen 40 can be fixedly installed by the mutual locking between the locking post 51 and the locking cavity 31, and the locking of the squeezing part 6. This method of disassembling and assembling the primary filter screen 40 is simple and convenient, and it is easy for users to inspect and replace the primary filter screen 40 in the later stage.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
