Abstract
Description
Technical Field
[0001] This utility model belongs to the field of paper machine equipment technology, specifically relating to a cloth dewatering collection device. Background Technology
[0002] In papermaking, the paper machine felt, as a key dewatering component, typically has a service life of 30 to 40 days. However, due to various factors, the dewatering performance of felts in different locations varies significantly. Firstly, fluctuations in pulp composition, changes in vacuum system negative pressure, and differences in felt design parameters inherently affect the basic dewatering capacity of felts in different areas. Secondly, even for the same felt, the degree of clogging and fiber wear dynamically changes throughout its service life, leading to variations in its actual dewatering state at different times. Furthermore, differences in felt dewatering directly impact core papermaking indicators and equipment operational stability: firstly, unstable dewatering leads to fluctuations in paper dryness, affecting energy consumption and physical properties of subsequent drying processes; secondly, abnormal dewatering can cause imbalances in paper machine operation, increasing the probability of paper breaks, felt misalignment, and other production malfunctions, thus reducing production efficiency. Summary of the Invention
[0003] The purpose of this invention is to address the above-mentioned problems by providing a device for collecting the amount of dehydrated wool fabric.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A felt dewatering collection device includes a felt water seal trough disposed below the felt of a paper machine and having a water-containing cavity. Several water collection tanks, each with a water-collecting cavity, are arranged horizontally within the felt water seal trough and are respectively positioned above and below the felt of the paper machine. Each water collection tank has a dewatering water inlet at its upper end and is closed at its lower end. An overflow hole is provided on one side of each water collection tank, located on the same horizontal plane. A liquid level measuring component is provided within the water collection tank. The felt water seal trough with its water-containing cavity facilitates the collection of water flowing out of the overflow hole. The dewatering water inlet and water-collecting cavity of the water collection tank, corresponding to different parts of the felt of the paper machine, facilitate the receipt of dewatered material from the felt. The liquid level measuring component can measure the dewatering amount at different parts of the felt, allowing users to observe the dewatering status of the felt, improving production efficiency, and ensuring papermaking results.
[0005] In the above-mentioned felt dewatering collection device, there are 6 water collection tanks of the same size. The water collection tanks are arranged adjacent to each other along the length of the felt 1 of the paper machine and are all located on the same horizontal plane, which facilitates the water collection tanks to receive the dewatering of the felt of the paper machine and ensures the water collection effect of the water collection tanks on various parts of the felt of the paper machine.
[0006] In the aforementioned felt dewatering collection device, the overflow holes are rectangular and are respectively located on the same side of the upper end of the water collection tank. When the dewatering amount reaches the overflow hole, the dewatering can flow through the overflow hole to the felt water seal tank. The height difference can be obtained through the liquid level measuring component, thereby obtaining the dewatering amount of each part of the paper machine felt.
[0007] In the aforementioned felt dewatering collection device, the overflow holes are all the same size and located on the same horizontal plane, which can ensure the accuracy of the liquid level measuring components in each water collection tank in measuring the amount of felt dewatering on the paper machine.
[0008] In the aforementioned felt dewatering collection device, the liquid level measuring component is a water tank level gauge installed in each water collection tank. The water tank level gauge is either an immersion level gauge or an ultrasonic level gauge. The water tank level gauge can continuously obtain the liquid level height under overflow conditions. When the liquid level height exceeds the liquid level height at the overflow hole, the liquid level difference can be obtained. The overflow flow rate can be obtained through the liquid level difference, thereby obtaining the dewatering amount of each part of the felt on the paper machine.
[0009] In the aforementioned felt dewatering collection device, the felt water seal trough is a rectangular box with an open top and a closed bottom, and the upper end of the water collection box does not extend beyond the open top of the felt water seal trough, which facilitates the water collection box to receive the dewatered felt from the paper machine through the open top.
[0010] In the aforementioned felt dewatering collection device, the total length of each water collection tank is equal to the length of the paper machine felt, and the length of the felt water seal groove is greater than the length of the paper machine felt. This ensures that each water collection tank receives the dewatering amount from each part of the paper machine felt, thus guaranteeing the detection effect of the dewatering amount from each part of the paper machine felt.
[0011] In the aforementioned felt dewatering collection device, the upper end of each water collection tank has a flow guiding structure. The flow guiding structure facilitates the flow of dewatered parts of the felt into each water collection tank, ensuring the detection effect of the dewatering amount of each part of the felt.
[0012] In the aforementioned felt dewatering collection device, the guiding structure includes two guide plates respectively disposed on the upper end of each water collection tank and located on both sides of the dewatering water inlet. The lower end of the guide plate is fixed inside the water collection tank and the upper end extends vertically upward to the felt side of the paper machine. Adjacent water collection tanks are separated by the same guide plate, and the dewatering of each part of the felt of the paper machine can be guided into each water collection tank through the guide plate, ensuring the measurement effect of the liquid level measuring component in the water collection tank on the dewatering of each part of the felt of the paper machine.
[0013] In the above-mentioned wool dewatering collection device, the upper end of the guide plate at the top of the water collection tank is flush with the top and the guide plates are arranged parallel to each other, which can ensure the guiding effect and improve the dewatering measurement effect.
[0014] Compared with existing technologies, the advantages of this utility model are: 1. The amount of water removed from various parts of the paper machine felt can be detected through several water collection tanks and liquid level measuring components, ensuring the detection effect; 2. The flow guiding structure can direct the dewatering of each part of the paper machine felt into each water collection tank, ensuring the detection effect of the dewatering amount of each part of the paper machine felt.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0017] like Figure 1 , Figure 2 As shown, this type of felt dewatering collection device includes a felt water seal trough 2 located below the felt 1 of a paper machine and having a water-containing cavity 21. Several water collection tanks 3, each corresponding to the felt 1 above and below, and each having a water collection cavity 31, are arranged horizontally within the felt water seal trough 2. Each water collection tank 3 has a dewatering water inlet 32 at its upper end and is closed at its lower end. An overflow hole 33 located on the same horizontal plane is provided on one side of each water collection tank 3. The housing 3 is equipped with a liquid level measuring component 4. The fabric water seal trough 2 with a water-containing cavity 21 can easily accommodate the water flowing out of the overflow hole 33. The dewatering water inlet 32 and the water collection cavity 31 of the water collection housing 3 are set to correspond to each part of the paper machine fabric 1, which can easily receive the dewatering of the paper machine fabric 1. The liquid level measuring component 4 can measure the amount of dewatering of each part of the paper machine fabric 1, so that users can observe the dewatering status of the paper machine fabric 1, improve production efficiency, and ensure the papermaking effect.
[0018] Specifically, there are 6 water collection tanks 3, all of the same size. The water collection tanks 3 are arranged adjacent to each other along the length of the paper machine felt 1 and are all located on the same horizontal plane. This facilitates the water collection tanks 3 to receive the dewatering of the paper machine felt 1 and ensures the water collection effect of the water collection tanks 3 on various parts of the paper machine felt 1.
[0019] The overflow holes 33 are rectangular and are respectively set on the same side of the upper end of the water collection tank 3. When the dewatering amount reaches the overflow hole 33, the dewatering can flow through the overflow hole to the felt water seal tank 2. The height difference can be obtained through the liquid level measuring component 4, thereby obtaining the dewatering amount of each part of the paper machine felt 1.
[0020] like Figure 1 , Figure 2 As shown, the overflow holes 33 are all the same size and located on the same horizontal plane, which can ensure the accuracy of the liquid level measuring components 4 in each water collection tank 3 in measuring the amount of water removed from the paper machine felt 1.
[0021] Furthermore, the liquid level measuring component 4 is a water tank level gauge 41 installed in each water collection tank 3, and the water tank level gauge 41 is an immersion level gauge or an ultrasonic level gauge. The water tank level gauge 41 can continuously obtain the liquid level height in the overflow state of the overflow hole 33. When the liquid level height exceeds the liquid level height at the overflow hole 33, the liquid level difference can be obtained. The overflow flow rate can be obtained through the liquid level difference, thereby obtaining the dewatering amount of each part of the paper machine felt 1.
[0022] The felt water seal trough 2 is a rectangular box with an open top and a closed bottom, and the upper end of the water collection tank 3 does not exceed the open top of the felt water seal trough 2, which makes it easy for the water collection tank 3 to receive the dewatering of the paper machine felt 1 through the open top.
[0023] Combination Figure 1 , Figure 2 As shown, the total length of each water collection tank 3 is equal to the length of the paper machine felt 1, and the length of the felt water seal groove 2 is greater than the length of the paper machine felt 1. This ensures that each water collection tank 3 receives the amount of water removed from each part of the paper machine felt 1, thus ensuring the detection effect of the amount of water removed from each part of the paper machine felt 1.
[0024] The upper end of the water collection tank 3 is equipped with a flow guiding structure 5. The flow guiding structure 5 facilitates the flow of dewatering water from various parts of the paper machine felt 1 into each water collection tank 3, ensuring the detection effect of the dewatering amount of each part of the paper machine felt 1.
[0025] Specifically, the flow guiding structure 5 includes two flow guiding plates 51 respectively set on the upper end of each water collection tank 3 and located on both sides of the dewatering water inlet 32. The lower end of the flow guiding plate 51 is fixed inside the water collection tank 3 and the upper end extends vertically upward to one side of the paper machine felt 1. Adjacent water collection tanks 3 are separated by the same flow guiding plate 51. The flow guiding plate 51 can guide the dewatering of each part of the paper machine felt 1 into each water collection tank 3, ensuring the measurement effect of the liquid level measuring component 4 in the water collection tank 3 on the dewatering amount of each part of the paper machine felt 1.
[0026] Combination Figure 1 , Figure 2As shown, the upper ends of the guide plates 51 on the upper end of the water collection tank 3 are flush and the guide plates 51 are arranged parallel to each other, which can ensure the guiding effect and improve the measurement effect of dewatering.
[0027] The principle of this embodiment is that the dewatering of each part of the paper machine felt 1 can be directed to different water collection tanks 3 through the flow guiding structure 5. The liquid level measuring component 4 in the different water collection tanks 3 can detect the amount of dewatering of each part of the paper machine felt 1, so as to ensure the detection effect of the amount of dewatering of the paper machine felt 1.
