DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0027] Please refer to Figures 1-7 The present application provides a technical solution:

[0028] The glass septic tank comprises a septic tank body 1 and a hanging filler assembly 2. The septic tank body 1 is connected with a water inlet pipe 3 and a drain pipe 4 at opposite ends. Two partition plates 5 are installed between the side walls of the inner cavity of the septic tank body 1. Through holes are formed in the upper parts of the two partition plates 5. A cleaning pipe 6 is connected to the top of the septic tank body 1 and located between the two partition plates 4. The hanging filler assembly 2 is installed in the cleaning pipe 6, and the fiber combined filler 21 of the hanging filler assembly 2 is located in the septic tank body 1.

[0029] The hanging filler assembly 2 comprises a mounting strip 22 which is installed between the inner walls of the cleaning pipe 6. A screw rod 23 is rotatably connected to the bottom of the mounting strip 22. One end of the screw rod 23 penetrates through the top of the mounting strip 22 and is provided with a rotating handle 24. A sliding block 25 is threadedly connected to the outer wall of the screw rod 23. A fixed block 26 is fixedly connected to the bottom of the screw rod 23. A plurality of fixed rods 27 are hingedly connected to the side walls of the fixed block 26 at equal angles. A plurality of groups of fiber combined fillers 21 are hung on the outer walls of the fixed rods 27 along the length direction of the fixed rods 27. The fixed rods 27 and the sliding block 25 are connected through a first connecting rod 28, and the first connecting rod 28 is hingedly connected to the fixed rods 27 and the sliding block 25.

[0030] Specifically, the bottom of the mounting strip 22 is fixedly connected with a first limiting rod 29, and the sliding block 25 is in sliding connection with the first limiting rod 29.

[0031] From the above description, it can be known that the first limiting rod can limit the sliding block, so that the sliding block can only slide up and down along the screw rod and cannot rotate.

[0032] Specifically, the inner cavity side wall of the cleaning pipe 6 is provided with a limiting ring 61 matched with the mounting strip 22, the top of the limiting ring 61 is provided with a bolt column 62 matched with the mounting strip 22, the bolt column 62 penetrates through the mounting strip 22 and is threadedly connected with a nut 63.

[0033] From the above description, it can be known that the cooperation of the bolt column and the nut can lock and fix the mounting strip, and the bolt column can also guide the installation of the mounting strip, facilitating the installation and position determination of the mounting strip.

[0034] Specifically, the screw rod 23 and the fixed block 26 are both hollow structures, the side wall of the fixed block 26 is provided with a hinged block 210 hingedly connected with the fixed rod 27, one end of the hinged block 210 penetrates through the side wall of the fixed block 26 and is fixedly connected with a second connecting rod 211, the outer wall of the second connecting rod 211 is fixedly connected with a driven bevel gear 212, the inside of the screw rod 23 is rotatably connected with a rotating rod 213, one end of the rotating rod 213 is located in the inner cavity of the fixed block 26 and is fixedly connected with a driving bevel gear 214, and the driving bevel gear 214 is in meshing connection with a plurality of driven bevel gears 212.

[0035] From the above description, it can be known that rotating the rotating rod can drive the driving bevel gear and the driven bevel gear to rotate, thereby driving the hinged block, the connecting rod and the fixed rod to rotate, so as to realize the winding and unwinding of the fiber combined filler, and facilitate the disassembly, assembly and carrying of the hanging filler assembly.

[0036] Specifically, the outer wall of the fixed rod 27 is rotatably connected with a rotating ring 271, and the rotating ring 271 is hingedly connected with the first connecting rod 28.

[0037] From the above description, it can be known that the fixed rod and the first connecting rod can relatively rotate, so that the rotation of the fixed rod does not interfere with the first connecting rod, and also does not affect the overturning of the fixed rod.

[0038] Specifically, the two baffles 5 are both provided with a cleaning opening 51 penetratingly formed below, the side face of the two baffles 5 close to each other is in sliding connection with a cover plate 52 in a height direction, the cover plate 52 blocks the cleaning opening 51, the top of the septic tank body 1 is fixedly connected with a hollow fixed box 53 surrounding the cleaning pipe 6, the inside of the fixed box 53 is provided with a connecting assembly 54 connected with the cover plate 52, and the connecting assembly 54 drives the cover plate 52 to slide up and down to open / close the cleaning opening 51.

[0039] From the above description, it can be seen that the cleaning opening is arranged on the partition plate, and the cleaning opening is closed by the cover plate, so that the septic tank can be divided into different treatment chambers through the partition plate during use, and when the septic tank is cleaned, the cleaning opening of the partition plate can be opened, so that the sludge in different chambers can flow into the middle chamber along the cleaning opening, and only one set of cleaning pipe can be used to clean the sludge in the septic tank.

[0040] Specifically, the connecting assembly 54 includes a fixed strip 541, one end of the fixed strip 541 penetrating through the side wall of the cleaning pipe 6 and being in sliding connection with the cleaning pipe 6, one end of the bolt column 62 penetrating through the fixed strip 541, and the fixed strip 541 being located between the limiting ring 61 and the mounting strip 22, one end of the fixed strip 541 located at the bottom of the inside of the fixed box 53 being fixedly connected with a sliding rod 542, the sliding rod 542 penetrating through the top of the septic tank body 1 and being connected with the cover plate 52, and the sliding rod 542 being in sliding connection with the septic tank body 1.

[0041] From the above description, it can be seen that when the hanging filler assembly is installed, the mounting strip can extrude the fixed strip to slide along the bolt column, and finally be locked and fixed by the nut, and the fixed strip can drive the sliding rod to slide downward, so that the cover plate closes the cleaning opening of the partition plate, and only one set of nut can be used to close the cleaning opening, which is simple and convenient.

[0042] Specifically, the side wall of the cleaning pipe 6 is provided with a sliding groove matched with the fixed strip 541.

[0043] From the above description, it can be seen that the sliding groove can limit the sliding position of the fixed strip, avoiding the fixed strip from being separated from the bolt column.

[0044] Specifically, the second limiting rod 543 is connected between the top of the inner cavity of the fixed box 53 and the septic tank body 1, and the second limiting rod 543 penetrates through the fixed strip 541, the spring 544 is sleeved on the outer wall of the second limiting rod 543, and the spring 544 is located below the fixed strip 541.

[0045] From the above description, it can be seen that when the hanging filler assembly is removed, the spring loses the extrusion force, and under the action of the restoring force, the fixed strip slides along the second limiting rod, so that the fixed strip drives the sliding rod and the cover plate to slide upward, and then the cleaning opening of the partition plate is opened, so that the sludge in different chambers can flow into the chamber between the two partition plates through the cleaning opening during cleaning, so that the cleaning of the sludge in the septic tank body is more thorough.

[0053] The use process of the glass septic tank is as follows:

[0054] During installation, the glass septic tank is buried underground, then the water inlet pipe 3 and the drain pipe 4 are respectively connected to the external sewage inlet pipe and the sewage discharge pipe, and the cleaning pipe 6 is connected to the cleaning opening on the ground, and the installation of the glass septic tank is completed;

[0055] During use, sewage flows into the septic tank through the water inlet pipe 3 for treatment, and the fiber combined filler 21 can make the microorganisms quickly form a biofilm and effectively cut bubbles during use, thereby improving the oxygen transfer rate and utilization rate, fully exchanging the water-air biofilm, and efficiently treating the organic matter in the water;

[0056] When the inside of the septic tank needs to be cleaned, the well cover connected with the septic tank cleaning pipe 6 is opened, and then the rotating rod 213 inside the screw rod 23 is rotated, the rotating rod 213 drives the driven bevel gear 212 to rotate through the driving bevel gear 214, thereby driving the second connecting rod 211, the hinged block 210 and the fixed rod 27 to rotate, so as to wind the fiber combined filler 21 suspended on the fixed rod 27 through the fixed rod 27, and in order to make the orientation of the hinged block 210 not affect folding after winding is completed, an arrow is arranged at the top of the rotating rod 213, so that the angle of the hinged block 210 can be judged through the arrow after winding is completed, after the fiber combined filler 21 is wound, the screw rod 23 is rotated by rotating the handle 24, the sliding block 24 and the first connecting rod 28 slide upward under the cooperation of the screw rod 23 and the first limiting rod 29, thereby driving the fixed rod 27 to fold along the hinged block 210 through the first connecting rod 28 to reduce the area of the suspended filler assembly 2, and then the nut 63 is rotated to take down the suspended filler assembly 2.
