Abstract
Description
Technical Field
[0001] This utility model relates to the field of exhaust gas purification and treatment technology for die-casting machines, specifically an adjustable overflow device for cleaning water tanks. Background Technology
[0002] Existing cleaning water tanks often use an overflow trough structure, but during the production of cleaning water tanks, the overflow trough is difficult to weld, has a large deformation, and is prone to incomplete or false welds.
[0003] In addition, the existing overflow troughs are in fixed positions, making it difficult to control the overflow speed by adjusting the overflow height; and water will splash into the overflow pipes during spraying. Utility Model Content
[0004] The purpose of this invention is to address the problems existing in the prior art by providing an adjustable overflow device for cleaning water tanks.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] An adjustable overflow device for cleaning water tanks includes an overflow pipe, characterized in that: the top of the overflow pipe is provided with an external threaded connector and an internal threaded connector, which are mutually matched and threaded together. By adjusting the threaded connection length between the external threaded connector and the internal threaded connector, the overflow level of the adjustable overflow device can be adjusted.
[0007] The internal threaded connector is welded to the top of the overflow pipe, and the external threaded connector can be embedded in the internal threaded connector, with the outer thread of the external threaded connector being rotatably connected to the inner thread of the internal threaded connector.
[0008] The external threaded connector is welded to the top of the overflow pipe, and the internal threaded connector can be sleeved on the external threaded connector, with the inner thread of the internal threaded connector and the outer thread of the external threaded connector being rotatably connected.
[0009] An overflow baffle plate welded to the inner side of the water tank is provided above the overflow pipe. The overflow baffle plate can limit the adjustment range of the external threaded joint and the internal threaded joint. The overflow baffle plate can also prevent water from splashing into the overflow pipe when the water tank is being cleaned by spraying.
[0010] The bottom of the overflow pipe is fixed inside the upper half of the clamp set, and the lower half of the clamp set is fixed inside the bottom plate of the water tank body.
[0011] The clamp set is concentric with the overflow hole on the bottom plate of the water tank.
[0012] The adjustable overflow device also includes a quick-release connector for connecting to an external overflow pipe. The top of the quick-release connector is fixedly connected to the bottom of the clamp set, and the quick-release connector is concentric with the overflow hole on the bottom plate of the water tank.
[0013] The adjustable overflow device also includes a quick-release connector for connecting an external overflow pipe. The quick-release connector is fixed to the bottom of the bottom plate of the water tank body and is concentric with the overflow hole on the bottom plate of the water tank body.
[0014] Working principle: The adjustable overflow device for cleaning water tanks provided by this utility model requires adjustment of the overflow level. If both the external and internal threaded connectors are positive threads, rotating the internal or external threaded connector at the top of the adjustable overflow device clockwise will lower the upper surface of the internal or external threaded connector, and rotating it counterclockwise will raise the upper surface of the internal or external threaded connector, thereby adjusting the overflow level; the reverse is also true.
[0015] Compared with the prior art, the present invention has the following advantages:
[0016] The adjustable overflow device provided by this utility model adjusts the overflow level by configuring a threaded connection structure. The internal or external threaded connector at the top of the overflow device can be adjusted by rotating clockwise or counterclockwise to achieve the adjustment of the overflow level. It has the characteristics of simple structure, convenience and practicality, and is suitable for widespread use. Attached Figure Description

[0020] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.
[0021] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended meaning of inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.
[0022] like Figure 1-2 As shown: An adjustable overflow device for cleaning water tank includes an overflow pipe 3. The top of the overflow pipe 3 is provided with an external threaded connector 4 and an internal threaded connector 5. The external threaded connector 4 and the internal threaded connector 5 are threadedly connected to each other. By adjusting the thread connection length between the external threaded connector 4 and the internal threaded connector 5, the overflow liquid level of the adjustable overflow device can be adjusted.
[0023] Regarding the matching of the overflow pipe 3 with the external threaded connector 4 and the internal threaded connector 5, there are two options: First, the internal threaded connector 5 is welded to the top of the overflow pipe 3, and the external threaded connector 4 can be inserted into the internal threaded connector 5, with the outer thread of the external threaded connector 4 rotatably connected to the inner thread of the internal threaded connector 5; second, the external threaded connector 4 is welded to the top of the overflow pipe 3, and the internal threaded connector 5 can be sleeved on the external threaded connector 4, with the inner thread of the internal threaded connector 5 rotatably connected to the outer thread of the external threaded connector 4. Option second is preferred because the inner diameter of the internal threaded connector 5 will be relatively larger in this case.
[0024] Furthermore, an overflow baffle 6 is welded to the inner side of the water tank body 1 above the overflow pipe 3. The overflow baffle 6 can limit the adjustment range of the external threaded connector 4 and the internal threaded connector 5. The overflow baffle 6 can also prevent water from splashing into the overflow pipe 3 when the water tank is being sprayed.
[0025] For the installation and fixing of the overflow pipe 3, the bottom of the overflow pipe 3 is fixed inside the upper half of the clamp set 2, and the lower half of the clamp set 2 is fixed inside the bottom plate of the water tank body 1, and the clamp set 2 is concentric with the overflow hole on the bottom plate of the water tank body 1; at this time, the adjustable overflow device also includes a quick-opening connector 7 for connecting the external overflow pipe, the top of the quick-opening connector 7 is fixedly connected to the bottom of the clamp set 2, and the quick-opening connector 7 is concentric with the overflow hole on the bottom plate of the water tank body 1.
[0026] Furthermore, the adjustable overflow device also includes a quick-opening connector 7 for connecting to an external overflow pipe. The quick-opening connector 7 is fixed to the bottom of the base plate of the water tank body 1 and is concentric with the overflow hole on the base plate of the water tank body 1.
[0027] The aforementioned external threaded connector 4 and internal threaded connector 5 can be machined to the required length to ensure the adjustment range of the overflow height. Example
[0028] This embodiment provides an adjustable overflow device for cleaning water tanks, including a water tank body 1, a clamp set 2, an overflow pipe 3, an external threaded connector 4, an internal threaded connector 5, an overflow baffle 6, and a quick-opening connector 7. The lower half of the clamp set 2 is welded to the inside of the bottom plate of the water tank body 1 and is concentric with the overflow hole on the bottom plate of the water tank body 1. The upper half of the clamp set 2 is welded to the bottom of the overflow pipe 3. The external threaded connector 4 is welded to the top of the overflow pipe 3. The internal threaded connector 5 rotates around the external threaded connector. The upper end of 4 and the internal threaded connector 5 are matched with the external threaded connector 4, both being positive or negative threads. The overflow baffle 6 is welded to the inner side of the water tank body 1 and is located directly above the internal threaded connector 5. There is a certain distance between the bottom of the overflow baffle 6 and the top of the internal threaded connector 5 so that the internal threaded connector 5 does not interfere with each other when adjusted upward. The quick-opening connector 7 used to connect the external overflow pipe is welded to the outside of the bottom plate of the water tank body 1 and is concentric with the overflow hole on the bottom plate of the water tank body 1.
[0029] When the overflow level in the cleaning water tank needs to be adjusted, the internal threaded connector 5 at the top of the adjustable overflow device can be rotated clockwise or counterclockwise to lower or raise the upper surface of the internal threaded connector 5, thereby adjusting the overflow level.
[0030] The adjustable overflow device provided by this utility model adjusts the overflow level by configuring a threaded connection structure. The internal threaded connector 5 or external threaded connector 4 at the top of the overflow device can be adjusted by rotating clockwise or counterclockwise to achieve the adjustment of the overflow level. It has the characteristics of simple structure, convenience and practicality, and is suitable for widespread use.
