Description

Technical Field

[0001] This utility model relates to the field of dyeing and printing wastewater treatment technology, and in particular to a wastewater treatment device for fabric dyeing and printing. Background Technology

[0002] Dyeing and printing wastewater is a type of industrial wastewater that is difficult to treat. It usually contains a large amount of fiber debris and dye slurry residue. The residual slurry still has a certain viscosity at room temperature, and it is easy to accumulate and clog the waterway with fiber debris during the wastewater treatment process, affecting the normal discharge of dyeing and printing wastewater. Therefore, in the treatment process of dyeing and printing wastewater, pretreatment of sedimentation and filtration is usually carried out. However, the existing pretreatment equipment is usually just a sedimentation tank with a filter screen, which has low treatment efficiency. At the same time, the filter screen itself is also easy to clog, requiring frequent replacement and cleaning, which reduces the filtration efficiency.

[0003] In existing patent CN213407897U, a fabric dyeing wastewater treatment device is disclosed. When filtering dyeing wastewater, a main conveying pipe transports the wastewater, and branch pipes are installed on both sides of the outer wall of the main conveying pipe. Each branch pipe has an inlet valve, one closed and one open. The branch pipes transport the dyeing wastewater to a filter bucket via connecting pipes. The filter bucket filters the wastewater through its filter holes. When a filter bucket needs to be replaced or cleaned, the open inlet valve is closed, and the closed inlet valve is opened. The wastewater then flows from another branch pipe into another filter bucket for filtration. The worker can then replace and clean the filter bucket that needs cleaning. This invention avoids reducing the filtration efficiency of the dyeing wastewater by replacing the filter bucket, thus improving the filtration efficiency.

[0004] However, in the existing methods described above, the filter cartridge is fastened to the outer shell with bolts, which requires a lot of manpower and time, making the disassembly and installation of the filter cartridge very inconvenient. Utility Model Content

[0005] The purpose of this utility model is to provide a wastewater treatment device for fabric printing and dyeing, which solves the problem that in the prior art, the filter barrel is fastened to the outer shell with bolts, which requires a lot of manpower and time, making the disassembly and installation of the filter barrel very inconvenient.

[0006] To achieve the above objectives, this utility model employs a wastewater treatment device for fabric printing and dyeing, comprising a shell, an outlet pipe, a main conveying pipe, a branch pipe, two inlet valves, two filter barrels, and two sets of mounting components. The branch pipe is connected to the shell and located above the shell. The main conveying pipe is connected to the branch pipe. The outlet pipe is connected to the bottom of the shell. The two inlet valves are respectively disposed on the branch pipe. The two filter barrels are located on the shell. Each set of mounting components is respectively connected to the shell and the filter barrels. The shell has two mounting holes.

[0007] The installation assembly includes a sealing plate, a connecting rod, a limiting rod, a movable sleeve, a pull rod, a retaining spring, and a retaining block. The sealing plate is fixedly connected to the filter bucket and is adapted to the mounting hole. The connecting rod is fixedly connected to the sealing plate and is located on the outer side wall of the sealing plate. The limiting rod is fixedly connected to the connecting rod and is located above the connecting rod. The movable sleeve is fixedly connected to the outer shell and is located on the outer side wall of the outer shell. The movable sleeve is also movably connected to the limiting rod. The limiting rod has a fixing hole. The movable sleeve has a groove. The pull rod is slidably connected to the movable sleeve and passes through the movable sleeve. The retaining block is fixedly connected to the pull rod and is located inside the movable sleeve. The two ends of the retaining spring are fixedly connected to the movable sleeve and the retaining block, respectively, and are located inside the groove.

[0008] The mounting assembly further includes a support rod, which is fixedly connected to the housing and located on the inner wall of the housing.

[0009] The installation assembly further includes a guide arc block, which is fixedly connected to the limiting rod and located on the outer side wall of the limiting rod.

[0010] The mounting assembly further includes a sealing gasket, which is fixedly connected to the housing and located within the mounting hole.

[0011] The wastewater treatment device for fabric printing and dyeing also includes an observation window, which is fixedly connected to the outer shell and located on the outer shell.

[0012] This utility model discloses a wastewater treatment device for fabric printing and dyeing. When disassembling the filter bucket from the outer casing, pulling the pull rod on the movable sleeve causes the pull rod to move the abutment block into the groove. Then, force is applied to pull the limiting rod, causing the limiting rod to move the sealing plate away from the mounting hole. The filter bucket moves along with this movement until it is completely disassembled, allowing for replacement or cleaning. When installing the filter bucket from the outer casing, the filter bucket is inserted into the outer casing through the mounting hole. Simultaneously, the limiting rod enters the movable sleeve, and pulling the pull rod on the movable sleeve causes the abutment block to enter the groove and compress the abutment spring. When the sealing plate enters the mounting hole, the pull rod is released, and the elastic force of the abutment spring causes the abutment block to enter the fixing hole of the limiting rod, thus installing the filter bucket onto the outer casing. This method facilitates easy disassembly and installation of the filter bucket from the outer casing, significantly saving manpower and time, and is simple to operate. Attached Figure Description

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] Please see Figures 1-6 This utility model provides a wastewater treatment device for fabric printing and dyeing: including a shell 101, an outlet pipe 102, a main conveying pipe 103, a branch pipe 104, two inlet valves 105, two filter barrels 106, and two sets of mounting components. The branch pipe 104 is connected to the shell 101 and is located above the shell 101. The main conveying pipe 103 is connected to the branch pipe 104. The outlet pipe 102 is connected to the bottom of the shell 101. The two inlet valves 105 are respectively disposed on the branch pipe 104. The two filter barrels 106 are located on the shell 101. Each set of mounting components is respectively connected to the shell 101 and the filter barrels 106. The shell 101 has two mounting holes 107.

[0023] The installation assembly includes a sealing plate 108, a connecting rod 109, a limiting rod 110, a movable sleeve 111, a pull rod 112, a retaining spring 113, and a retaining block 114. The sealing plate 108 is fixedly connected to the filter bucket 106 and is adapted to the mounting hole 107. The connecting rod 109 is fixedly connected to the sealing plate 108 and is located on the outer side wall of the sealing plate 108. The limiting rod 110 is fixedly connected to the connecting rod 109 and is located above the connecting rod 109. The movable sleeve 111 is fixedly connected to the outer shell 101. Located on the outer side wall of the outer casing 101, the movable sleeve 111 is also movably connected to the limiting rod 110. The limiting rod 110 has a fixing hole 120. The movable sleeve 111 has a groove 115. The pull rod 112 is slidably connected to the movable sleeve 111 and passes through the movable sleeve 111. The abutment block 114 is fixedly connected to the pull rod 112 and is located inside the movable sleeve 111. The two ends of the abutment spring 113 are fixedly connected to the movable sleeve 111 and the abutment block 114 respectively and are located inside the groove 115.

[0024] In this embodiment, when filtering dyeing and printing wastewater, the main conveying pipe 103 conveys the wastewater, and the branch pipe 104 is equipped with an inlet valve 105. One inlet valve 105 on the branch pipe 104 is in a closed state, and the other is in an open state. The dyeing and printing wastewater falls into the filter tank 106, which filters the wastewater. When a filter tank 106 needs to be replaced or cleaned, the open inlet valve 105 is closed, and the closed inlet valve 105 is opened. When the inlet valve 105, which is in a closed state, is opened, the dyeing wastewater flows from another branch pipe 104 into another filter barrel 106 for filtration. At this time, the staff replaces and cleans the filter barrel 106 that needs cleaning. When removing the filter barrel 106 from the outer casing 101, the pull rod 112 is pulled on the movable sleeve 111. The pull rod 112 drives the abutment block 114 into the groove 115, and then the limiting rod 110 is pulled. 110 drives the sealing plate 108 to disengage from the mounting hole 107, and the filter barrel 106 moves accordingly until the filter barrel 106 is disassembled, and then the filter barrel 106 is replaced or cleaned; when installing the filter barrel 106 on the outer shell 101, the filter barrel 106 is inserted into the outer shell 101 through the mounting hole 107, and at the same time the limiting rod 110 enters the movable sleeve 111, and pulls the pull rod 112 on the movable sleeve 111, and the abutment block 114 enters. The retaining spring 113 is pressed into the groove 115. When the sealing plate 108 enters the mounting hole 107, the pull rod 112 is released. The elastic force of the retaining spring 113 drives the retaining block 114 into the fixing hole 120 of the limiting rod 110, thereby installing the filter bucket 106 on the outer shell 101. By adopting the above method, it is possible to easily disassemble and install the filter bucket 106 on the outer shell 101, which greatly saves manpower and time and is easy to operate.

[0025] Furthermore, the mounting assembly also includes a support rod 118, which is fixedly connected to the housing 101 and located on the inner sidewall of the housing 101.

[0026] In this embodiment, by providing the support rod 118 inside the outer casing 101, the support rod 118 supports the filter canister 106 inside the outer casing 101, thereby improving the stability of the filter canister 106 inside the outer casing 101.

[0027] Furthermore, the mounting assembly also includes a guide arc block 119, which is fixedly connected to the limiting rod 110 and located on the outer side wall of the limiting rod 110.

[0028] In this embodiment, by providing the guide arc block 119 on the limiting rod 110, the limiting rod 110 can easily enter the movable sleeve 111 using the guide arc block 119, making the operation simple.

[0029] Furthermore, the mounting assembly also includes a sealing gasket 116, which is fixedly connected to the housing 101 and is located within the mounting hole 107.

[0030] In this embodiment, by providing the sealing gasket 116, the gap of the sealing plate 108 in the mounting hole 107 is greatly reduced, thereby increasing the sealing effect of the sealing plate 108 in the mounting hole 107.

[0031] Furthermore, the wastewater treatment device for fabric printing and dyeing also includes an observation window 117, which is fixedly connected to the outer casing 101 and located on the outer casing 101.

[0032] In this embodiment, the observation window 117 is provided on the outer casing 101, which allows the staff to easily see whether the filter canister 106 is clogged, and facilitates the replacement or cleaning of the filter canister 106.

[0033] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model.
