Description

Technical Field

[0001] The utility model relates to the technical field of cooler sewage discharge auxiliary devices, in particular to a cooler sewage discharge auxiliary device. Background Art

[0002] Mechanical vacuum pump units are widely used in many industrial fields, including chemical, food, oil, electronics, and metallurgy. They are composed of a combination of two or more vacuum pumps, depending on the required vacuum level and process load. Typically, a Roots vacuum pump and a backing vacuum pump are connected in series to form a single unit. When the process load is very high, one or more vacuum pump units can be connected in parallel. A mechanical vacuum pump unit can consist entirely of Roots vacuum pumps, but Roots vacuum pumps that exhaust directly into the atmosphere are relatively inefficient, so most units are connected in series with a Roots vacuum pump and a backing vacuum pump. Fore-stage vacuum pumps include water ring vacuum pumps, screw vacuum pumps, and oil-sealed mechanical vacuum pumps, each with its own advantages and disadvantages, and the type of backing vacuum pump to be used must be determined based on the process load and the type of gas being pumped.

[0003] When using existing Roots water ring vacuum coolers, the valve on the drain pipe is usually closed. Before each operation, the valve needs to be opened to drain the waste liquid inside the cooler and filter out impurities. If the drain valve is a manual valve, staff must be on-site to operate it, and the filter equipment must be cleaned regularly, which is time-consuming and labor-intensive. Utility Model Content

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] Example 1

[0031] Reference Figure 1-4 A cooler sewage auxiliary device includes a sewage pipe 1 connected to the cooler. An electric sewage valve 2 is installed on the sewage pipe 1, which allows the sewage pipe 1 to be opened remotely through electronic control, eliminating the need for workers to visit the site to open and close the valve each time, thus reducing workload. A sewage filter box is connected to one end of the sewage pipe 1 to filter out impurities.

[0032] Specifically, the sewage filter box in this embodiment includes a box body 3 and a filter assembly located inside the box body 3. A sewage inlet 32 ​​and a sewage outlet 33 are provided on the box body 3. The sewage pipe 1 is connected to the sewage inlet 32. The sewage discharged from the cooler is discharged into the box body 3 through the sewage inlet 32, and then discharged through the sewage outlet 33 to enter the next treatment process.

[0033] In order to extend the maintenance cycle of the filter screen 4, the filter assembly in this embodiment includes a plurality of filter screens 4 and a switching mechanism for switching each filter screen 4 to the filter port in turn. Then, a guide plate 5 is set inside the box body 3 (supported and fixed by a bracket inside the box body 3 through fasteners), and the sewage inlet 32 ​​is located on the upper part of the guide plate 5. The vertical projection surface of the guide plate 5 is designed to be annular, and the upward end of the guide plate 5 is an inclined surface 51, and the filter screen 4 covers the lower end of the central opening 52 of the guide plate 5. Through such a design, the inclined surface 51 can collect, gather, and guide the sewage that enters the sewage inlet 32 ​​and falls, and then flow down through the central opening 52 of the guide plate 5. This method can also leave space for the switching of each filter screen 4 in the box body 3.

[0034] The switching mechanism in this embodiment includes a rotating bracket 61, a switching shaft 62 fixedly connected to the rotating bracket 61, and a drive mechanism 63 for driving the switching shaft 62. One end of the shaft is rotatably connected to the bottom of the housing 3, while the other end of the shaft extends out of the surface of the housing 3 and is connected to the drive mechanism 63. The drive mechanism 63 in this embodiment can be implemented by a servo motor and a reducer to precisely control the rotation angle of the rotating bracket 61. This allows each filter screen 4 to be accurately moved below the central opening of the guide plate 5 during switching, allowing sewage to enter the corresponding filter screen 4. Therefore, the rotating bracket 61 and each filter screen 4 are preferably located below the guide plate 5.

[0035] To accommodate the filter screen 4, this embodiment provides several mounting holes 611 on the rotating bracket 61. These mounting holes 611 are distributed circumferentially around the rotating bracket 61. Each filter screen 4 is then mounted on a respective mounting hole 611, securing the filter screen 4 and facilitating easy removal of the filter screen 4. To accommodate the rotating bracket 61, this embodiment designates the filter screen 4 as having a U-shaped axial cross-section. Furthermore, a support ring 41 is provided on top of the filter screen 4 to secure the filter screen 4 to the rotating bracket 61.

[0036] In addition, in order to facilitate cleaning, replacement and maintenance of the filter screen 4, this embodiment also provides a box cover 31 on the top of the box body 3. The box cover 31 can be a flip-top structure to avoid accidental loss of the box cover 31. Therefore, the box cover 31 can be located on the upper part of the rotating bracket 61 through a hinge.

[0037] During use, this embodiment can be remotely controlled to drain wastewater through the electric drain valve 2. If the filter screens 4 in operation need to be cleaned or maintained during the draining process, the electric drain valve 2 can be closed first, and the drive mechanism 63 can be activated to rotate the rotatable bracket 61 to a certain angle, thereby rotating the adjacent filter screens 4 to the lower portion of the central opening of the guide plate 5, allowing the wastewater filter box to continue filtering. The electric drain valve 2 can then be opened. If the spare filter screens 4 are clogged or affect the normal draining of the cooler, the box cover 31 can be opened by a staff member to clean or replace the filter screens 4.

[0038] Example 2

[0039] On the basis of the above-mentioned embodiment, this embodiment further provides two clamping blocks 71 on the surface of the box body 3 to facilitate fixing the sewage pipe 1 and prevent the sewage pipe 1 from shaking, which would affect the fit with the sewage inlet 32. And through a ball or a slide rail 75 (this embodiment preferably uses a dovetail slide rail 75, which also has a limiting effect), the clamping block 71 is slidably connected to the surface of the box body 3, which facilitates the movement of the fixed block 72 on the surface of the box body 3 and reduces resistance. Then, this embodiment provides an adjustment screw 73 that is rotatably connected to the clamping block 71 on the fixed block 72, and then the adjustment screw 73 is threadedly connected to the fixed block 72. By rotating the adjustment screw 73, the distance between the clamping block 71 and the sewage pipe 1 can be adjusted. A knob can be provided at the end of the adjustment screw 73 away from the clamping block 71 for easy operation, or a driver can be provided to drive the adjustment screw 73 to rotate. This embodiment will not be described in detail.

[0040] The side of each clamping block 71 that contacts the sewage pipe 1 is a concave arc-shaped structure and is provided with a rubber pad 74 to improve the stability when contacting the sewage pipe 1 .

[0041] In addition, this embodiment further provides an observation port 8 on one side of the box body 3, and a transparent observation window 81 is provided on the observation port 8, which is convenient for staff to observe the internal situation of the box body 3 during remote monitoring or on-site inspection and maintenance, and to replace and clean the filter screen 4 in time.

[0042] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
