Description

Technical Field

[0001] This utility model relates to the field of filter drying technology, specifically to a filter dewatering device. Background Technology

[0002] A filter is an accessory that uses filter paper to filter impurities or gases. It generally refers to automotive filters, which are engine components. Based on different filtration functions, they are divided into: oil filters, fuel filters, and diesel filters, commonly known as the "three filters." Adding the cabin air filter, they are commonly called the "four filters."

[0003] After automotive filters are manufactured, they need to undergo a water test to check their airtightness. The filter is placed in a water testing device, completely submerged below the water surface. Compressed air is pumped into the filter, and the presence of air bubbles in the water is observed. If no air bubbles appear, the filter has good airtightness.

[0004] After the water filter is inspected, the surface of the filter will contain moisture. Generally, the staff needs to manually wipe the moisture off the surface, which is a very inefficient method. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a filter dewatering device that achieves automatic wind-powered dewatering and improves work efficiency.

[0006] This utility model is achieved through the following technical solution:

[0007] A filter dewatering device includes a support box, an air duct, and a fan. The top of the support box is provided with a conveying mechanism, on which a tray for holding the filter is placed. The top of the support box is provided with a mounting bracket for mounting the air duct. The air inlet end of the air duct is connected to the fan, and the air outlet end of the air duct is mounted on the mounting bracket, with the air outlet end of the air duct facing the support box below. The device also includes a switching mechanism, which is electrically connected to the fan and is used to turn the fan on or off.

[0008] More preferably, the switching mechanism includes a sliding switch and a pressure rod installed on the inner side wall of the support box. The sliding switch is electrically connected to the fan and has a sliding pin for turning the fan power on or off. The pressure rod is rotatably connected to the support box through a rotating shaft. A toggle lever is provided at the end of the rotating shaft away from the pressure rod. The end of the toggle lever abuts against the sliding pin of the sliding switch. A return spring is provided at the end of the sliding pin away from the toggle lever.

[0009] More preferably, there are two conveying mechanisms, which are respectively arranged on both sides of the top of the support box, and the pressure rod is arranged between the two conveying mechanisms, with the end of the pressure rod inclined in the conveying direction of the conveying mechanism.

[0010] In a further preferred embodiment, there are several air ducts and fans. The air ducts are installed along the direction of the conveying mechanism. At the same time, the air outlets of the several air ducts are staggered in a direction perpendicular to the conveying mechanism. The number of switching mechanisms is the same as the number of fans, and the switching mechanisms correspond one-to-one with the fans.

[0011] More preferably, the end of the actuating lever is provided with a barb for actuating the sliding pin.

[0012] More preferably, the tray is provided with a number of filter holes for filtering moisture from the surface of the air-drying filter.

[0013] The beneficial effects of this utility model are:

[0014] 1) The filter dewatering device of this utility model allows the filter to be automatically dewatered by airflow through the air duct above while being conveyed on the conveying mechanism, thereby improving the dewatering efficiency of the filter. At the same time, the filter holes on the tray increase the airflow and permeability, further improving the dewatering effect.

[0015] 2) The switching mechanism of this utility model cleverly employs a pressing rod during the conveying of the tray. After the pressing rod is pressed, it rotates the toggle lever, pushing the sliding pin to the position of opening the fan. Thus, during the conveying process, when the tray reaches the air duct, the fan is automatically turned on. After the tray passes the end of the pressing rod, the return spring pushes the sliding pin to the position of closing the fan under the action of elasticity. Thus, after the tray passes the end of the pressing rod, the fan is automatically turned off, improving work efficiency, saving energy and reducing costs.

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Attached Figure Description

[0026] A filter water removal device, such as Figure 1-3As shown, the system includes a support box 1. Two conveying mechanisms 2 are located inside the top of the support box 1, one on each side of the top. Each conveying mechanism 2 has a tray 3 capable of holding multiple filters simultaneously. Filters that have undergone an airtightness test in water are conveyed from one end of the top of the support box 1 to the other. Preferably, the tray 3 has several filter holes 4 for filtering moisture from the surface of the air-dried filters. A drain pipe can be installed at the bottom of the support box 1 for drainage. A mounting bracket 5 is located at the top of the support box 1 for mounting... The mounting bracket 5 is used to install the air duct 6. The air inlet end of the air duct 6 is connected to the fan 7, and the air outlet end of the air duct 6 is installed on the mounting bracket 5, with the air outlet end of the air duct 6 facing the support box 1 below. Preferably, there are several air ducts 6 and fans 7. The air ducts 6 are respectively installed in the direction of the conveying mechanism 2, so that there is air force along the conveying direction of the conveying mechanism 2 to perform air force dewatering on the filter. At the same time, the air outlet ends of several air ducts 6 are staggered in the direction perpendicular to the conveying direction of the conveying mechanism 2, which facilitates providing air force to the filter on the tray 3 from multiple angles for dewatering.

[0027] The device also includes several switching mechanisms, such as Figure 1-4 As shown, the number of switching mechanisms is the same as the number of fans 7, and there is a one-to-one correspondence between the switching mechanisms and fans 7. The switching mechanisms are electrically connected to the fans 7, and one switching mechanism turns one fan 7 on or off. Figure 4 As shown, the switching mechanism includes a sliding switch 8 installed on the inner wall of the support box 1. The sliding switch 8 is electrically connected to the fan 7 and is used to turn the power of the fan 7 on or off. The sliding switch 8 has a sliding pin 9 for turning the power of the fan 7 on or off. The switching mechanism also includes a pressure rod 10 rotatably connected to the support box 1. The pressure rod 10 is located between the two conveying mechanisms 2. One end of the pressure rod 10 is rotatably connected to the support box 1 via a rotating shaft 11. The end of the pressure rod 10 is inclined towards the conveying direction of the conveying mechanism 2, so that the tray 3 can press down on the pressure rod 10 during the conveying process. The end of the rotating shaft 11 away from the pressure rod 10 is provided with a toggle rod 12. The end of the toggle rod 12 abuts against the sliding pin 9 of the sliding switch 8. Preferably, the toggle rod... The end of 12 is provided with a barb 13, which is used to move the sliding pin 9 to a further position. When the sliding pin 9 is close to the end of the lever 12, the sliding switch 8 is in the closed state, that is, the fan 7 is in the closed state. When the sliding pin 9 is away from the end of the lever 12, the sliding switch 8 is in the open state, that is, the fan 7 is in the open state. The end of the sliding pin 9 away from the lever 12 is provided with a return spring 14, which is fixed on the mounting plate 15. The mounting plate 15 is fixed on the inner side wall of the support box 1. Preferably, along the conveying direction of the conveying mechanism 2, each pressure rod 10 is set in front of the air duct 6 connected to the corresponding fan 7, and the length of the pressure rod 10 is the same as the straight distance from the rotating shaft 11 to the outer wall of the far end of the air duct 6.

[0028] The working process of this utility model's filter water removal device is as follows:

[0029] Several filters are placed in the tray 3, and then the tray 3 is placed on the conveying mechanism 2. The conveying mechanism 2 is started to convey the filters. When the tray 3 passes the pressure rod 10, the pressure rod 10 is pressed down and rotated by the tray 3, which drives the actuating rod 12 at the other end of the rotating shaft 11 to rotate towards the sliding pin 9 of the sliding switch 8. The actuating rod 12 moves the sliding pin 9 towards the return spring 14. The sliding switch 8 turns on the fan 7. After the fan 7 starts, it delivers air to the filters on the conveying mechanism 2 through the air duct 6. Force is applied to the filter to dry it. When the tray 3 has completely passed the end of the pressure rod 10, the return spring 14 returns to its original position and moves the sliding pin 9 toward the toggle rod 12. The sliding switch 8 turns off the fan 7, and the air duct 6 stops blowing air. After the toggle rod 12 rotates, it drives the pressure rod 10 to rotate back to its original position. Every time the tray 3 and the filter pass through a pressure rod 10, the corresponding fan 7 turns on to air-force the filter to remove water. After the tray 3 is conveyed away from the end of a pressure rod 10, the corresponding fan 7 is turned off and stops providing air force.
