Description

Technical Field

[0001] The utility model relates to the technical field of quenching pools, in particular to a quenching pool impurity cleaning device. Background Art

[0002] Quenching is a metal heat treatment process that rapidly cools the metal to achieve a certain hardness and strength. During the quenching process, impurities may fall into the quenching pool for the following reasons: There may be some non-metallic inclusions in the metal, such as oxides, sulfides, etc. At high temperatures, these inclusions may be dissolved or dispersed in the metal, but during quenching, the metal cools rapidly, the solubility of the inclusions in the metal lattice decreases, and particles or aggregates may be formed, eventually leaving the metal surface and entering the quenching pool.

[0003] Metal processing companies usually have large quenching pools that are 3-5 meters long and wide and 2-3 meters deep. It is difficult to clean impurities from the liquid in the quenching pool. Usually, impurities are cleaned out manually or electrically with a scoop net, which is inefficient.

[0004] The applicant previously disclosed a heat treatment device for breaker bolts, with the publication (announcement) number CN219907764U. The device uses a flowmaker to drive the liquid in the pool to rotate around the inner wall of the circular pool body, and uses centrifugal force to collect impurities into a filter installed on the inner wall of the pool body. This method has the following disadvantages: first, the flowmaker is expensive and easily damaged by long-term immersion in the quenching pool. Second, the centrifugal movement of the quenching liquid will cause the quenching agent and other components added to the quenching liquid to also undergo centrifugal movement, resulting in the quenching agent being unable to effectively contact the quenching metal, thereby reducing the quenching effect. Utility Model Content

[0005] The utility model aims to solve the problem that impurities in the quenching pool liquid are inconvenient to clean, and proposes a quenching pool impurity cleaning device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A quenching pool impurity cleaning device includes a plate assembly arranged above the bottom wall of the quenching pool, the plate assembly has a plurality of parallel flow channels, both ends of the flow channels are connected to the quenching pool, a filter cover is provided at one end of the flow channel, the open end of the filter cover points to the flow channel, the cleaning device also includes an air pump, the air pump outlet is connected to an air pipe, the air pipe is at least partially inserted in the flow channel, and the air outlet end of the air pipe points to the filter cover.

[0008] The plate assembly comprises a horizontally arranged transverse plate, a plurality of parallel vertical plates are fixedly connected or integrally formed at the bottom of the transverse plate, the bottom ends of the vertical plates are fixedly supported on the bottom wall of the quenching tank, and the flow channel is located between adjacent vertical plates.

[0009] The air pipe includes a main pipe, a shunt pipe, and a branch pipe. One end of the main pipe is connected to the air outlet of the air pump, and the other end of the main pipe is connected to the shunt pipe. Each shunt port on the shunt pipe is connected to a branch pipe, and the branch pipe is at least partially inserted in the flow channel.

[0010] The radial cross-sectional dimension of the branch pipe is smaller than the cross-sectional dimension of the flow channel.

[0011] The length of the branch pipe inserted into the flow channel is greater than three-fifths of the length of the flow channel and less than four-fifths of the length of the flow channel.

[0012] The side walls of the quenching pool facing both ends of the flow channel are arc-shaped surfaces.

[0013] The horizontal cross section of the quenching tank is rectangular.

[0014] A lifting rod is installed on the filter cover.

[0015] The utility model proposes a quenching pool impurity cleaning device, which has the beneficial effect of making the liquid in the quenching pool form a circulating flow state, and the flowing quenching liquid repeatedly passes through the filter cover, and the impurities therein are blocked by the filter cover, and then the filter cover can be taken out and cleaned. Since an air pipe is installed in the quenching pool, the device has a relatively simple structure, is not easy to be damaged, and has a lower air pump cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 2 It is a schematic diagram of the top view structure of the flow channel and branch pipe distribution of the utility model.

[0018] In the figure: quenching tank 1, air pump 2, side wall 3, diverter pipe 4, branch pipe 5, flow channel 6, plate assembly 7, filter cover 8, lifting rod 9, main pipeline 10, air pipe 11, vertical plate 12, horizontal plate 13. DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-2A quenching pool impurity cleaning device includes a plate assembly 7 arranged above the bottom wall of the quenching pool 1, the plate assembly 7 has a plurality of parallel flow channels 6, both ends of the flow channels 6 are connected to the quenching pool 1, a filter cover 8 is provided at one end of the flow channel 6, and the open end of the filter cover 8 points to the flow channel 6. The cleaning device also includes an air pump 2, and the air outlet of the air pump 2 is connected to an air pipe 11, the air pipe 11 is at least partially inserted in the flow channel 6, and the air outlet end of the air pipe 11 points to the filter cover 8.

[0021] During the quenching process of the device or after the quenching is completed, the air pump 2 is started, and the air pump 2 blows toward the flow channel 6 through the air pipe 11. The gas pushes the quenching liquid at the rear end of the flow channel 6 to one end, and the liquid is replenished from the front end of the flow channel 6, so that the liquid in the quenching pool 1 forms a circulating flow state, and the flowing quenching liquid repeatedly passes through the filter cover 8, and the impurities therein are blocked by the filter cover 8. Thereafter, the filter cover 8 can be taken out and cleaned, and the impurities in the quenching liquid can be cleaned more easily. Since the air pipe is installed in the quenching pool of the device, the structure is relatively simple, not easy to be damaged, and the air pump cost is lower.

[0022] As an embodiment, the plate assembly 7 includes a horizontally arranged transverse plate 13, a plurality of parallel vertical plates 12 are fixedly connected or integrally formed at the bottom of the transverse plate 13, the bottom ends of the vertical plates 12 are fixedly supported on the bottom wall of the quenching tank 1, and the flow channels 6 are located between adjacent vertical plates 12. Through the assembly of the vertical plates 12 and the transverse plates 13, when the vertical plates 12 are supported on the bottom wall of the quenching tank 1, a plurality of parallel flow channels 6 are formed, which has a simple structure and is easy to manufacture.

[0023] As an implementation method, refer to Figure 2 The air pipe 11 includes a main pipe 10, a diversion pipe 4, and a branch pipe 5. One end of the main pipe 10 is connected to the air outlet of the air pump 2, and the other end of the main pipe 10 is connected to the diversion pipe 4. Each diversion port on the diversion pipe 4 is connected to a branch pipe 5. The branch pipe 5 is at least partially inserted in the flow channel 6. The airflow of the main pipe 10 is diverted to multiple branch pipes 5 through the diversion pipe 4, so that the airflow enters each flow channel separately.

[0024] In order to ensure that the liquid can circulate between the flow channel 6 and the quenching pool 1 , the radial cross-sectional dimension of the branch pipe 5 is smaller than the cross-sectional dimension of the flow channel 6 , so that a flow gap is formed between the branch pipe 5 and the wall of the flow channel 6 .

[0025] The length of the branch pipe 5 inserted into the flow channel 6 is greater than three-fifths of the length of the flow channel 6 and less than four-fifths of the length of the flow channel 6, so that a larger part of the branch pipe 5 is inserted into the flow channel 6, that is, the air outlet end of the branch pipe 5 is close to the right end of the flow channel 6, reducing the thrust of the airflow in the branch pipe 5 to promote the movement of the fluid.

[0026] refer to Figure 1The side walls 3 of the quenching pool 1 facing the two ends of the flow channel 6 are arc-shaped surfaces, and the arc-shaped surface structure can make the quenching liquid flow counterclockwise better on the vertical plane.

[0027] As an implementation mode, the horizontal cross section of the quenching tank 1 is a rectangle.

[0028] A lifting rod 9 is installed on the filter cover 8, and the filter cover 8 is taken out and placed in the quenching tank 1 by the lifting rod 9. In order to prevent the filter cover 8 from being blown away by the movement of fluid, a buckle structure that opens and closes up and down can be installed between the filter cover 8 and the plate assembly, or a card groove can be set between the filter cover 8 and the bottom wall of the quenching tank 1. The device does not limit how to fix it, and it can even be fixed to the quenching tank 1 by fixing the filter cover 8 with the lifting rod 9.

[0029] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technical solution, concept, and design obtained by equivalent replacement or change based on the technical solution and utility model concept of the utility model by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
