Description

Technical Field

[0001] This utility model relates to the field of wastewater filtration technology, and in particular to a wastewater filtration mechanism for a low-temperature evaporative heat pump concentration device. Background Technology

[0002] When treating wastewater with a low-temperature evaporative heat pump concentration system, a physical pretreatment unit needs to be installed upstream. This intercepts and removes any suspended solids, particulate impurities, fibers, colloids, some precipitates, or larger substances that may cause scaling from the wastewater before it enters the main evaporation and concentration system. The purpose is to protect the subsequent evaporation system from blockage, wear, scaling, and contamination, ensuring the stable, efficient, and long-term reliable operation of the entire system.

[0003] Traditionally, a filter assembly is installed at the inlet pipe of a low-temperature evaporative heat pump concentration device to filter suspended solids from wastewater. However, this filter assembly requires periodic disassembly and cleaning during prolonged use. Traditional filter assemblies are often assembled using flanges, necessitating the removal of numerous bolts during disassembly and maintenance. This method of disassembly and assembly is cumbersome and reduces the efficiency of filter assembly maintenance for users. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wastewater filtration mechanism for low-temperature evaporative heat pump concentration equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wastewater filtration mechanism for a low-temperature evaporative heat pump concentration device includes a low-temperature evaporative heat pump concentration device body. An inlet pipe is provided on one side of the device body, and a detachable mounting base is installed inside the inlet pipe. A filter assembly is installed inside the mounting base, and side plates are fixedly installed on both sides of the inlet pipe at the mounting base. Multiple detachable locking pins are inserted between the side plates, and corresponding locking cavities are provided on the mounting base for each locking pin. A locking pin is vertically movable inside each side plate, and a locking cavity is provided on each locking pin for each locking pin. A threaded pin is rotatably installed on the top of each side plate.

[0007] Furthermore, in a preferred configuration, the inlet pipe has a cavity, and an installation cavity is formed outward from the upper part of the cavity, and the installation cavity is adapted to the mounting base.

[0008] In addition, in a preferred structure, one end of each of the locking pins is fixedly connected to the pull plate, and a through cavity is adapted to be opened on the side plate for each corresponding locking pin.

[0009] Furthermore, in a preferred configuration, each side plate has an inwardly opening adjustment cavity, and each adjustment cavity is connected to the through cavity.

[0010] In addition, in a preferred configuration, multiple guide posts are vertically fixedly installed in each of the adjustment cavities, the locking posts are guided to move by the guide posts, and one end of each locking post on both sides is fixedly connected by a connecting rod.

[0011] In addition, in a preferred structure, the top of each side plate is provided with a threaded cavity facing downwards, the threaded cavity is connected to the adjustment cavity, the threaded post is adapted to be located in the threaded cavity and rotates, and a pressure plate is fixedly provided at the bottom of each threaded post.

[0012] The beneficial effects of this utility model are as follows: by interlocking the locking post and the locking cavity, and by limiting the locking post with the locking post and the locking cavity, the mounting base can be fixedly installed. This allows the filter assembly to be conveniently assembled into the inlet pipe. This method of disassembling and assembling the filter assembly is simple and convenient, making it easy for users to disassemble and clean the filter assembly. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] Reference Figure 1-6 A wastewater filtration mechanism for a low-temperature evaporative heat pump concentration device includes a low-temperature evaporative heat pump concentration device body 1. An inlet pipe 11 is provided on one side of the body 1. A detachable mounting base 2 is installed inside the inlet pipe 11. A filter assembly 22 is installed inside the mounting base 2. Side plates 3 are fixedly installed on both sides of the inlet pipe 11 at the mounting base 2. Multiple detachable locking pins 51 are inserted between the two side plates 3. A locking cavity 21 is provided on the mounting base 2 corresponding to each locking pin 51. A locking pin 4 is vertically movable inside each side plate 3. A locking cavity 52 is provided on each locking pin 51 corresponding to each locking pin 4. A threaded pin 6 is rotatably provided on the top of each side plate 3.

[0022] The inlet pipe 11 has a cavity 12, and the cavity 12 has an installation cavity 13 extending outward from the top, which is adapted to the mounting base 2. Sealing gaskets are provided on the contact surfaces between the cavity 12, the installation cavity 13, and the mounting base 2 to ensure the sealing of the cavity 12.

[0023] One end of each locking post 51 is fixedly connected to the pull plate 5, and each side plate 3 has a corresponding through cavity 31. Each side plate 3 has an adjustment cavity 32 extending inward, and the adjustment cavity 32 communicates with the through cavity 31.

[0024] The adjusting cavity 32 contains multiple vertically fixed guide posts 33, which guide the locking posts 4 to move. One end of each locking post 4 is fixedly connected by a connecting rod 41. The guide posts 33 improve the stability of the locking posts 4 during movement.

[0025] Each side plate 3 has a downward-facing threaded cavity 34 at its top, which communicates with the adjusting cavity 32. A threaded post 6 is adapted to rotate within the threaded cavity 34, and a pressure plate 61 is fixedly installed at the bottom of each threaded post 6. It is worth noting that a prior art threaded damping self-locking structure is provided between the threaded cavity 34 and the threaded post 6 to ensure stability during engagement. This is prior art and will not be elaborated upon further.

[0026] In this embodiment, the low-temperature evaporative heat pump concentration equipment body 1 reduces the pressure inside the evaporator to a boiling point of 30-50℃ using a vacuum pump, achieving energy-saving evaporation in conjunction with heat pump circulation. The core components include a tube / plate heater, an evaporation chamber, and a heat pump system. The filter assembly 22 primarily employs modular multi-layer filters (coarse + medium + fine), intercepting suspended solids and metal particles through gradually varying pore sizes. This is prior art and not a major technical problem addressed in this technical solution; therefore, it will not be elaborated upon further in this application.

[0027] Furthermore, when the user needs to install the filter assembly 22, he / she only needs to insert the mounting base 2 into the mounting cavity 13, so that the filter assembly 22 can be assembled into the liquid inlet pipe 11. At this time, the locking cavity 21 on the mounting base 2 is adapted and aligned with the through cavity 31 on the side plate 3.

[0028] Next, the user simply inserts the locking pins 51 into the through cavity 31 and the locking cavity 21 using the pull plate 5. This allows the mounting base 2 to be fixed by the interlocking between the locking pins 51 and the locking cavity 21. At this time, the locking cavities 52 on the locking pins 51 are all aligned with the locking pins 4.

[0029] Next, the user simply needs to press down the locking pin 4 with the connecting rod 41 to lock the locking pin 4 into the locking cavity 52. ​​Then, the user can rotate the threaded pin 6 downward with the knob so that the pressure plate 61 at the bottom of the threaded pin 6 presses against the top of the locking pin 4 to fix the locking pin 4. This will achieve the fixed installation of the mounting base 2 and the filter assembly 22.

[0030] Furthermore, when the user needs to disassemble and clean the filter assembly 22, simply rotate the threaded post 6 upwards using the knob to release the pressure plate 61 from pressing the locking post 4. Then, lift the locking post 4 upwards using the connecting rod 41 to release the mutual jamming between the locking post 4 and the locking cavity 52. ​​Finally, simply pull out the locking post 51 using the pull plate 5 to disassemble the mounting base 2 and the filter assembly 22.

[0031] In this utility model, the mounting base 2 can be fixedly installed by the mutual locking between the locking post 51 and the locking cavity 21, and by the locking post 4 and the locking cavity 52 limiting the locking post 51. This allows the filter assembly 22 to be conveniently assembled into the liquid inlet pipe 11. This method of disassembling and assembling the filter assembly 22 is simple and convenient, making it easy for users to disassemble and clean the filter assembly 22.

[0032] 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.
