Description

Technical Field

[0001] This utility model relates to the field of perforation machine technology, and in particular to a novel automatic filtration and water addition device for perforation machines. Background Technology

[0002] A drilling machine, also called an electrical discharge drilling machine, punching machine, small hole machine, or fine hole discharge machine, works by using a continuously moving, vertically moving thin copper tube (called an electrode wire) as an electrode to perform pulsed spark discharge on the workpiece to remove metal and shape it. Existing drilling machines require continuous water cooling of the mandrel when operating under high temperature and pressure to ensure their service life.

[0003] For example, patent document CN211803075U discloses a mandrel cooling system for a drilling machine. This system includes a mandrel, a mandrel rod, and a mandrel rod carriage. One end of the mandrel rod is fixedly connected to the mandrel, and the other end is connected to the mandrel rod carriage. An outlet pipe and an inlet pipe are installed inside the mandrel rod. A sealing block and a support block are fixedly connected to the left end of the mandrel rod, and a support block is also fixedly connected to the right end of the mandrel rod. The outlet pipe and the inlet pipe pass through the two support blocks and the sealing block to enter the mandrel cooling chamber. A telescopic device is installed on the outlet pipe, and a sealing ring is installed at the contact point between the sealing block and the outlet pipe and the inlet pipe. A pump is connected to the water tank outlet, and a filter is installed between the pump and the water tank outlet. The pump outlet is connected to the mandrel rod inlet via an inlet hose. The mandrel rod outlet is connected to a cooler via an outlet hose, and the cooler outlet is connected to the water tank. A water inlet is installed on the top of the water tank, and a drain outlet is installed at the bottom of the water tank.

[0004] However, although the above system can cool the mandrel through the cooler, it is prone to the following problems during use: 1. Water is lost during the processing of the workpiece, and the operator needs to add water to the water tank from time to time. It is easy to forget to add water, resulting in insufficient water in the water tank, which in turn leads to the failure of the drilling machine water pump and reduces the processing quality of the workpiece; 2. The inlet and outlet pipes are connected to the same water tank, which causes the wastewater generated during the process to flow directly back into the water tank, causing the water in the tank to become turbid. Utility Model Content

[0005] This utility model provides a novel automatic filtration and water addition device for a perforating machine, which solves the technical problem in the prior art that the perforating machine requires manual water addition to the water tank during processing, which can easily lead to water pump failure and poor workpiece processing quality due to untimely water addition.

[0006] To solve the above problems, the novel automatic filtration and water addition device for perforating machines provided by this utility model adopts the following technical solution:

[0007] A novel automatic filtration and water supply device for a perforating machine includes:

[0008] The main body of the device has a partition inside to divide its internal space into a clean water tank and a wastewater tank, and the top of the clean water tank is connected to an inlet pipe.

[0009] A float switch is installed inside the water tank and connected to the water inlet pipe to control the delivery of water in the water inlet pipe;

[0010] A filter bucket is installed inside the wastewater tank. The wastewater tank is a water storage area except for the area where the filter bucket is installed. The filter bucket is connected to the machine tool water tank through a drain pipe to purify the wastewater discharged from the machine tool water tank and discharge the purified water into the water storage area.

[0011] An overflow hole is provided at the top of the partition to discharge the treated water in the sewage tank into the clean water tank, thereby realizing water recycling.

[0012] The beneficial effects of the novel automatic filtration and water addition device for perforating machines provided by this utility model are:

[0013] 1. By installing a float switch connected to the inlet pipe in the water purification tank, automatic water filling of the water purification tank can be realized. When the water level in the water purification tank drops, the float switch drops and opens, and the inlet pipe fills the water purification tank with water. As the water level in the water purification tank rises, the float switch rises and closes, and the inlet pipe stops filling the water purification tank with water.

[0014] 2. By installing a filter bucket in the wastewater tank, the wastewater discharged from the machine tool water tank is purified. The purified water is then discharged into the storage area for storage. During the storage process, impurities mixed in with the water settle at the bottom of the storage area, and the treated water in the storage area is divided into bottom sediment and supernatant. When the water level in the storage area rises to the height of the overflow hole, the supernatant is discharged from the overflow hole into the clean water tank, thus realizing the recycling of water.

[0015] Through the above-mentioned design, this utility model effectively solves the technical problem in the prior art that water needs to be manually added to the water tank during the perforation process, which can easily lead to water pump failure and poor processing quality due to untimely water addition.

[0016] Furthermore, a connector is provided at the outlet of the water inlet pipe, and the float switch is connected to the connector.

[0017] Furthermore, the float switch includes a piston installed in the connector, a connecting rod connected to the end of the piston away from the connector, and a float connected to the end of the connecting rod away from the piston.

[0018] Furthermore, the number of overflow holes is multiple.

[0019] Furthermore, the plurality of overflow holes are evenly spaced horizontally on the top of the partition.

[0020] Furthermore, the number of filter canisters is two.

[0021] Furthermore, both filter barrels are provided with water inlets at the top, and the outlet end of the drain pipe is connected to a water distribution pipe assembly. The water distribution pipe assembly includes a main water pipe connected to the outlet end of the drain pipe, and two branch pipes are connected to the end of the main water pipe away from the drain pipe. The ends of the two branch pipes extend to the water inlets of the two filter barrels respectively. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] It should be noted that the main concept of the novel automatic filtration and water filling device for perforating machines provided by this utility model is as follows: by setting a float switch connected to the inlet pipe in the clean water tank, the float switch can automatically open or close according to the change of water level in the clean water tank, thereby controlling the water delivery in the inlet pipe and realizing automatic water filling of the clean water tank; by setting a filter bucket in the wastewater tank, the wastewater discharged from the machine tool water tank can be purified to obtain treated water. After the treated water is discharged into the water storage area in the wastewater tank, the impurities it contains will settle during the storage process, so that the treated water is divided into bottom sediment and supernatant in the water storage area. When the water level in the water storage area rises to the opening height of the overflow hole, the supernatant is discharged from the overflow hole into the clean water tank, thus realizing the recycling of water.

[0028] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0029] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0030] Example 1 of the novel automatic filtration and water addition device for perforating machines provided by this utility model:

[0031] like Figure 1 As shown, the novel automatic filtration and water supply device for a perforating machine includes a main body 1. A partition 2 is installed inside the main body 1, dividing the internal space into a clean water tank 3 and a wastewater tank 4. The clean water tank 3 is equipped with a float switch connected to an inlet pipe 5 at its top, which controls the water flow within the inlet pipe 5. The wastewater tank 4 contains a filter barrel 6, which is connected to the machine tool water tank via a drain pipe 7 to purify the wastewater discharged from the machine tool water tank and discharge the purified water into the wastewater tank 4. An overflow hole 8 is provided at the top of the partition 2 to discharge the treated water from the wastewater tank 4 into the clean water tank 3, thus achieving water recycling.

[0032] The following describes the structure of the float switch and its connection with the inlet pipe 5. The float switch includes a piston, with a connecting rod 10 connected to the right end of the piston, and a float ball 11 connected to the right end of the connecting rod 10. A connector 9 is provided at the outlet of the inlet pipe 5, and the left end of the piston is installed in the connector 9. The float ball 11 floats and sinks according to the water level in the water tank 3, thereby driving the piston to move within the connector 9, thus controlling the water delivery in the inlet pipe 5.

[0033] Next, we will describe the filter canister 6, its installation in the wastewater tank 4, and the connection between the filter canister 6 and the drain pipe 7. There are two filter canisters 6, which are arranged side by side in the wastewater tank 4. Each filter canister 6 has an inlet at its top. The outlet of the drain pipe 7 is connected to a branch pipe assembly. The branch pipe assembly includes a main water pipe 12 connected to the outlet of the drain pipe 7. The end of the main water pipe 12 (i.e., the end away from the drain pipe 7) is connected to two branch pipes 13. The ends of the two branch pipes 13 extend to the inlets of the two filter canisters 6, respectively, for discharging wastewater into the filter canisters 6.

[0034] Finally, the arrangement of the overflow holes 8 on the partition 2 is described. Multiple overflow holes 8 are provided on the top of the partition 2, and the multiple overflow holes 8 are arranged in a row and evenly distributed at intervals along the horizontal direction (i.e., the width direction of the partition 2) on the top of the partition 2.

[0035] The working principle of the novel automatic filtration and water supply device for the perforating machine provided by this utility model is as follows: When the water level in the clean water tank 3 is too low, the float ball 11 falls, driving the connecting rod 10 to move down, thereby driving the piston located in the connector 9 to be pulled out. The float switch is in the open state, and the water inlet pipe 5 injects water into the clean water tank 3. The clean water tank 3 supplies water to the perforating machine through the water supply pipe and other water supply structures. The sewage generated in the machine tool water tank flows through the drain pipe 7, the main water pipe 12 and the branch pipe 13 in sequence into the filter bucket 6. The filter bucket 6 filters and purifies the sewage to obtain treated water. The treated water is discharged from the bottom of the filter bucket 6 and enters the water storage area. During the storage of the treated water in the water storage area, the impurities mixed in it settle at the bottom of the water storage area. The treated water in the water storage area is divided into bottom sediment and supernatant. When the water level in the water storage area rises to the height of the overflow hole 8, the supernatant is discharged from the overflow hole 8 into the clean water tank 3 to realize the recycling of water.

[0036] Example 2 of the novel automatic filtration and water addition device for perforating machines provided by this utility model:

[0037] Its main difference from Example 1 is:

[0038] In Example 1, there are two filter canisters.

[0039] In this embodiment, the number of filter canisters is one or more.

[0040] Example 3 of the novel automatic filtration and water addition device for perforating machines provided by this utility model:

[0041] Its main difference from Example 1 is:

[0042] In Example 1, multiple overflow holes are arranged in a row at equal intervals along the horizontal direction (i.e., the width direction of the partition) on the top of the partition.

[0043] In this embodiment, multiple overflow holes are arranged in two rows at equal intervals along the horizontal direction (i.e., the width direction of the partition) on the top of the partition, and the two rows of overflow holes are staggered vertically.

[0044] Based on the above description in this specification, those skilled in the art will also understand that the following terms, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," which indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0045] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
