Description

Technical Field

[0001] This utility model belongs to the field of filter technology, specifically relating to a filter that aids in drainage and a waste heat recovery device for a stenter. Background Technology

[0002] To ensure the filter maintains high efficiency during the filtration process, a cleaning mechanism is installed inside the filter. The cleaning mechanism washes the filter screen, removing lint and impurities that are attached to it. The cleaning water is then discharged through the drain port at the bottom of the filter.

[0003] In the prior art, because the bottom of the filter is horizontal, although most of the cleaning water after rinsing is discharged from the drain outlet, a small portion will be dispersed at the bottom and cannot be concentrated at the drain outlet. For example, in the patent document CN212039166U, entitled "An Improved Backwashing Filter", water accumulation will cause odor to be generated inside the filter and premature aging of internal components, which is not conducive to the long-term use of the filter. Therefore, this utility model proposes a filter that helps with drainage and a waste heat recovery device for a setting machine. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned technical problems existing in the prior art, and to provide a filter that helps drain water and a waste heat recovery device for a setting machine, so that the cleaning water is concentrated at the drain outlet and discharged, keeping the inside of the filter body dry.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A filter that aids in drainage includes a filter body, a cleaning mechanism within the filter body, a drain outlet for draining water, and a guide within the filter body for receiving cleaning water from the cleaning mechanism and directing the cleaning water to the drain outlet.

[0007] Furthermore, the guide uses an inclined plate with one side higher than the other, with the side of the inclined plate with the lower height facing the drain outlet, so that the cleaning water is concentrated in the drain outlet and discharged.

Detailed Implementation

[0040] like Figures 1 to 9 As shown, this utility model discloses a filter that aids in drainage. It includes a filter body 1, a cleaning mechanism within the filter body 1, and a drain outlet 21 for drainage. A guide component, specifically a base plate 5, is provided within the filter body 1. The base plate 5 receives the cleaning water from the cleaning mechanism. One side of the base plate 5 is higher than the other, with a natural transition in the middle. The lower side faces the drain outlet 21, allowing the cleaning water to concentrate and drain out within the outlet 21. A buffer groove 6 is provided on the lower side of the base plate 5, connecting the drain outlet 21. The buffer groove 6 reduces the water flow velocity, preventing water from splashing against the sidewalls of the filter body 1 due to excessive flow speed, thus facilitating the drainage of cleaning water from the drain outlet 21.

[0041] The filter body 1 contains a filter assembly 4 and a second connector 12. The second connector 12 has a second channel 20, which is snap-fitted to the side of the filter assembly 4, thus fixing the filter assembly 4 inside the housing. The filter assemblies 4 are arranged along the width of the housing, with adjacent filter assemblies 4 angled together to form a zigzag structure. The filter assembly 4 includes at least one first connector 2 and at least two filter units 3. The first connector 2 has a first channel 19, which is fitted into the side of the filter unit 3, allowing adjacent filter units 3 to be arranged side by side, increasing the filtration area of ​​the filter assembly 4, which in turn increases the width of the zigzag structure and improves the velocity of exhaust gas. The filter unit 3 has a handle 11, which provides better grip when the user separates the two filter units 3.

[0042] The cleaning mechanism includes a rotating mechanism 13, a first spray pipe 9, and a second spray pipe 10. The first connector 2 has a through hole, and the first spray pipe 9 is disposed in the through hole. The rotating mechanism 13 is connected to the first spray pipe 9 and is used to drive the first spray pipe 9 to rotate. The second spray pipe 10 is arranged at intervals along the axial direction of the first spray pipe 9. The body of the second spray pipe 10 faces the filter assembly 4. The body of the second spray pipe 10 has a cleaning port 22, which faces the filter assembly 4. The second spray pipe 10 is connected to the first spray pipe 9, and the first spray pipe 9 is connected to an external water pipe, so that cleaning water is sprayed from the cleaning port 22 to the filter assembly 4.

[0043] The waste heat recovery device for the stenter includes an exhaust duct 18 and a fire damper 17. The exhaust duct 18 is used to connect to the stenter, and a filter is installed in the exhaust duct 18. The filter body 1 has an inlet 7 and an outlet 8. The inlet 7 allows waste gas to enter the filter body 1, and the outlet 8 allows filtered clean gas to exit the filter body 1. The outlet 8 includes port A and port B, with port A having a larger area than port B and a natural transition in the middle. The inlet 7 includes port E and port F, with port E having a larger area than port F and a natural transition in the middle. A flared structure is provided at the inlet 7, and a constricted structure is provided at the outlet 8 to reduce noise when liquids or gases pass through. The fire damper 17 is installed on the exhaust duct 18 connecting to the inlet 7 and / or the exhaust duct 18 connecting to the outlet 8, and is used to block the passage of smoke and flames. The fire damper 17 is installed on the exhaust air duct 18 connected to the inlet 7 to prevent flames from other equipment from damaging the filter through the exhaust air duct 18; it is also installed on the exhaust air duct 18 connected to the outlet 8 to prevent flames from the filter from affecting other equipment through the exhaust air duct 18.

[0044] This invention also includes a pressure detection element, a first controller, and an alarm system. The pressure detection element employs a first sensor 16, a second sensor 23, and a differential pressure sensor. The first sensor 16 is located at the inlet to sense the pressure generated by the airflow at the inlet. The second sensor 23 is located at the outlet to sense the pressure generated by the airflow at the outlet. Both the first sensor 16 and the second sensor 23 are electrically connected to the differential pressure sensor. The differential pressure sensor calculates the pressure difference between the first sensor 16 and the second sensor 23 and converts the pressure difference into a signal, which is output to the first controller. The first controller receives and processes the signal and selectively triggers the alarm system based on its judgment. When the first controller determines that the pressure difference exceeds a preset value, it activates the alarm system, prompting the user to check the internal condition of the filter body 1 to prevent internal blockage.

[0045] This utility model also includes a third sensor 24, a second controller, and a fire protection system. The third sensor 24 is installed in the exhaust air duct 18 or the filter body 1. The third sensor 24 is used to detect temperature and send the temperature signal to the second controller. When the second controller determines that the temperature data is greater than the preset value, the second controller triggers the fire protection system. The fire protection system can usually be a fire protection system using water spray fire extinguishing device or non-water fire extinguishing agent such as dry powder fire extinguishing.

[0046] The filter body 1 or the exhaust duct 18, or both, are equipped with observation ports. The observation ports can be set with different viewing angles so that the user can see the complete situation inside the filter body 1. A cover plate 14 is movably installed on the observation port, and a handle 15 is installed on the cover plate 14. The user opens and closes the cover plate 14 by using the handle 15.
