[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0037] like Figure 1-4 As shown, the cooling mechanism of the engraving machine includes:

[0038] The housing has a support ring fixedly connected to its inner wall.

[0039] The filter assembly is placed on the top side of the support ring and is used to filter wastewater after rinsing.

[0040] The auxiliary component is installed on the top side surface of the housing and is used to scrape away impurities that the filter component intercepts.

[0041] The sealing part is installed at the bottom of the filter assembly and is used for sealing the bottom of the filter assembly and adjusting the impurity collection space.

[0042] The cooling pipe includes an inlet pipe, a nozzle, and an inlet connector. A nozzle is installed at one end of the inlet pipe, and an inlet connector is installed at the other end. The inlet connector is connected to the cooling water inlet circulation pipe.

[0043] The cooling water sprayed from the nozzle mixes with the wastewater inside the shell, and the temperature of the wastewater is reduced through heat exchange, so that the wastewater is cooled while being filtered, meeting the water temperature requirements for subsequent recycling.

[0044] Three legs are fixedly installed on the bottom side of the shell, and the three legs are distributed in a triangular shape at the bottom of the shell.

[0045] The shell serves as the basic frame of the device, and the three legs arranged in a triangular pattern on the bottom provide stable support for the whole, ensuring that the device will not shake due to water flow impact or component operation during operation.

[0046] A discharge connector is fixedly installed on the left side of the bottom of the casing. The discharge connector is used to connect to the water circulation pipe. The discharge connector on the left side of the bottom of the casing is responsible for discharging the treated water out of the device and into the subsequent circulation system.

[0047] The filter assembly includes a fixed frame, a plug-in post, a filter screen, and a discharge cylinder. The filter screen is fixedly connected to the inner wall of the bottom end of the fixed frame, and the discharge cylinder is fixedly connected to the bottom side of the fixed frame. The bottom end of the discharge cylinder penetrates the bottom side surface of the housing.

[0048] In this embodiment, when the wastewater to be treated enters the housing, the frustum-shaped filter screen filters the wastewater, intercepting impurities (such as particulate pollutants, debris, etc.). The filtered water passes through the filter screen and enters the bottom of the housing, awaiting further treatment or discharge. The discharge cylinder on the bottom side of the fixed frame provides a collection and discharge channel for the impurities intercepted on the filter screen. The impurities gather towards the discharge cylinder under the action of gravity.

[0049] There are four insertion posts, which are arranged in a ring on the bottom side of the fixed frame. The insertion posts engage with the limiting holes. The support ring on the inner wall of the housing is used to support the filter assembly. It engages with the insertion posts of the filter assembly through the limiting holes, so as to achieve precise positioning and stable installation of the filter assembly.

[0050] The auxiliary components include a mounting bracket, fixing bolts, a servo motor, a rotating shaft, a connecting shaft, and a scraper. The mounting bracket is connected to the top side surface of the housing via fixing bolts. A servo motor is fixedly mounted on the top of the mounting bracket. The output end of the servo motor is connected to a rotating shaft. A connecting shaft is fixedly connected to the bottom side surface of the rotating shaft. A scraper is fixedly connected to the end of the connecting shaft.

[0051] When impurities accumulate to a certain level on the surface of the filter screen, the servo motor starts, and its output drives the rotating shaft to rotate. The rotating shaft drives the scraper to rotate synchronously through the connecting shaft. Because the scraper is in close contact with the inner wall of the frustum-shaped filter screen, it can completely scrape off the impurities attached to the filter screen during rotation. The scraped-off impurities slide down the inner wall of the filter screen to the discharge cylinder, avoiding impurities clogging the filter screen pores and affecting the filtration speed.

[0052] There are two fixing bolts, and the ends of the two fixing bolts are threaded to the top side surface of the housing.

[0053] The scraper is attached to the inner wall of the filter screen, and the scraper is attached to the inside of the filter screen which is shaped like a frustum.

[0054] The sealing part includes a connecting cylinder, a connecting column, a sealing plug, and a locking seat. The connecting cylinder is sleeved on the surface of the discharge cylinder. The connecting column is fixedly connected to the inner wall of the bottom end of the connecting cylinder. The sealing plug is fixedly connected to the end of the connecting column. The locking seat is threaded onto the surface of the discharge cylinder.

[0055] When impurities need to be collected, the locking seat is rotated to fix the connecting cylinder. At this time, the sealing plug blocks the bottom of the discharge cylinder, forming a closed impurity collection space. When impurities need to be discharged, the locking seat is loosened and the connecting cylinder is rotated, causing the sealing plug to move downwards and opening the bottom channel of the discharge cylinder. The impurities are discharged through the discharge cylinder under the action of gravity. The timing of discharge can be flexibly controlled according to the amount of impurities accumulated, reducing the accidental loss of clean water.

[0056] The sealing plug is slidably connected to the inner wall of the discharge cylinder, and the connecting cylinder is coaxially arranged with the sealing plug. The inner wall of the connecting cylinder is threadedly connected to the outer surface of the discharge cylinder.

[0057] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.

[0058] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
