Description

Technical Field

[0001] The utility model belongs to the field of formaldehyde content detection, and particularly relates to a device for detecting the formaldehyde content of wood-based panels. Background Art

[0002] Wood-based panels are generally made by bonding wood chips and thin sheet materials with urea-formaldehyde glue and then hot-pressing. Among them, urea-formaldehyde

[0003] glue is synthesized from urea and formaldehyde, so wood-based panels contain formaldehyde. When the formaldehyde concentration in the indoor air reaches a certain level, people will feel uncomfortable, which can induce symptoms such as bronchial asthma, cough, stuffiness, general discomfort, and allergic skin diseases. Therefore, it is necessary to detect the formaldehyde content of wood-based panels to ensure compliance with national standards. The current commonly used formaldehyde detection method is as follows: Cut the wood-based panel into squares and put them into a flask with water; then filter the soaking solution of the wood-based panel to obtain a filtrate, and further determine the formaldehyde content by detecting the filtrate;

[0004] However, the current filtration of the soaking solution of wood-based panels has the following disadvantages:

[0005] 1. The existing filtration device can only achieve single filtration. If multiple filtrations are required to further reduce the impurities in the filtrate and improve the accuracy of formaldehyde detection, repeated operations are needed, which is not only cumbersome but also inefficient;

[0006] 2. The existing filtration device requires personnel to hold the flask by hand and slowly pour it into the filtration funnel, which not only increases the labor intensity of the personnel but also has the risk of dropping the hand and overturning the container.

[0007] In view of the above deficiencies, there is a need for a device for detecting the formaldehyde content of wood-based panels, which can not only conveniently achieve multiple filtrations of the soaking solution of wood-based panels, but also does not require personnel to continuously hold the container to perform the filtration operation, reducing the labor intensity and the risk of dropping the hand and overturning the container.

The ends of the bottom plate 1 and the top plate 2 are connected by a connecting plate 3. The structure between the bottom plate 1, the top plate 2 and the connecting plate 3 is integrally formed. To improve stability, the length of the bottom plate 1 is longer than that of the top plate 2, and the specific length is set according to requirements. It is recommended that the length of the bottom plate 1 is at least 1.5 times longer than that of the top plate 2; A first container 5 for holding the liquid to be filtered is provided on the top plate 2. The first container 5 can be a device such as a beaker or a conical flask; And a diversion pipe 8 is provided on the side of the first container 5, and a valve 7 for controlling the liquid flow rate is provided on the diversion pipe 8. The valve 7 adopts a traditional ball valve or angle valve, etc., as long as it can control the liquid flow rate;

[0034] The overall structure of the diversion pipe 8 is in a right-angled shape; The horizontal pipeline of the diversion pipe 8 is connected to the first container 5, and the vertical pipeline of the diversion pipe 8 is located above the filter funnel 17 at the top. The liquid flow rate is controlled by the valve 7, and the liquid to be filtered is sent into the filter funnel 17 at the top through the diversion pipe 8. To ensure the stability of the liquid introduced into the filter funnel 17, a rubber tube can be sleeved at the end of the diversion pipe 8 to reduce the drop; A notch 4 is provided on the top plate 2, and the diversion pipe 8 is located above the notch 4, which is convenient for the operation and placement of the diversion pipe 8 of the first container 5. The size and shape of the notch 4 are selected according to actual needs, and reference can also be made to this appendix Figure 1 and2 Structure. A second container 6 for receiving filtered liquid is provided on the bottom plate 1. The second container 6 can be devices such as a beaker or a conical flask. Between the first container 5 and the second container 6, several filter funnels 17 are successively arranged from top to bottom. The filter funnels 17 are common funnels, and the specific principle will not be elaborated here. The structure different from the traditional funnel will be further described below in combination with the function of the filter funnel 17.

[0035] A support device 9 is provided outside the filter funnel 17. One end of the support device 9 is detachably connected to the filter funnel 17; the other end of the support device 9 is detachably connected to the connecting plate 3. The filter funnels 17 are successively and stably supported from top to bottom by the support device 9. To improve the convenience of detachable connection, the support device 9 includes support rods 10 arranged in parallel. One ends of the support rods 10 are connected by a semi-circular arc rod 11; and a weir 13 is provided on the periphery of the filter funnel 17, and the weir 13 is located above the arc rod 11 to support the filter funnel 17. Among them, to improve the support stability of the arc rod 11, as shown in the attachment Figure 3 , a parallel rod is added between the connection of the arc rod 11 and the support rod 10 to further improve the support stability; a right-angled engaging rod 12 is provided at the other end of the support rod 10, and a bushing 14 matching the engaging rod 12 is provided on the side of the connecting plate 3.

In practical applications, to ensure that the liquid completely flows out of the first container 5, the diversion pipe 8 is located at the bottom side of the first container 5. In this way, the bottom end of the right-angled diversion pipe 8 is lower than the bottom wall of the first container 5, resulting in inconvenient storage of the first container 5. To reduce this height difference, a heightening plate 15 is provided at the bottom of the first container 5; the heightening plate 15 is adhesively connected to the first container 5 through nano glue, which is convenient for disassembly and assembly; the heightening plate 15 is made of glass or plastic material, and preferably a lighter plastic material.
