Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 4 A formaldehyde pumping feeding device which is easy to maintain comprises a delivery pump 1, wherein the inlet of the delivery pump 1 is connected with a liquid inlet pipe 2, a liquid inlet port 4 is installed on the side of the other end of the liquid inlet pipe 2, a liquid outlet pipe 3 is connected with the outlet of the delivery pump 1, a liquid outlet port 5 is installed on the side of the other end of the liquid outlet pipe 3, and a first valve 6 is installed on both the liquid outlet port 5 and the liquid inlet port 4. It should be noted that, in actual use, the liquid inlet port 4 is connected with a storage tank of formaldehyde aqueous solution, and the liquid outlet port 5 is connected with urea-formaldehyde resin glue processing equipment. Under the operation of the delivery pump 1, the formaldehyde aqueous solution in the storage tank is transported to the urea-formaldehyde resin glue processing equipment, thereby producing the required urea-formaldehyde resin glue for use in the manufacture of artificial boards.

[0024] like Figure 1 and Figure 2 As shown, a water pump 7 is connected to the end of the liquid outlet pipe 3 away from the delivery pump 1 through a connecting pipe 8, the connecting pipe 8 is connected to the outlet of the water pump 7, and a water inlet pipe 10 is installed at the inlet of the water pump 7. Water is passed through the water inlet pipe 10, and the water pump 7 will deliver clean water to the liquid outlet pipe 3 and the liquid inlet pipe 2, thereby cleaning the inner wall of the pipeline and the delivery pump 1.

[0025] A purification box 11 is installed on the end of the liquid inlet pipe 2 away from the delivery pump 1. A plurality of purification components for purifying formaldehyde are arranged in the purification box 11, and a discharge port 13 is installed at the bottom of the end of the purification box 11 away from the liquid inlet pipe 2. Figure 3 and Figure 4As shown, a plurality of slots 14 arranged at intervals are provided on the top of the purification box 11, and the purification assembly includes a frame 15, the frame 15 corresponds to the slots 14, and the edge of the frame 15 is in clearance with the inner wall of the purification box 11, and an activated carbon plate 16 is installed in the frame 15, and a sealing plate 17 is installed on the top of the frame 15, and the sealing plate 17 is placed on the top surface of the purification box 11, and a handle 18 is provided on the top of the sealing plate 17, and the frame 15 is inserted into the purification box 11 from the slots 14 by pulling and plugging, which is convenient for the active carbon plate 16 to be inserted into the purification box 11. Replacement of the activated carbon plate 16; wherein, a limit seat 19 is also provided in the purification box 11, and the limit seat 19 is installed and fixed along the inner wall of the purification box 11, the cross section of the limit seat 19 is "U"-shaped, and the edge of the frame 15 is disposed in the inner groove of the limit seat 19, and an elastic rubber pad is also installed on the inner side of the limit seat 19, which stabilizes the frame 15 in the purification box 11, and the elastic rubber pad will seal the gap between the frame 15 and the limit seat 19, thereby ensuring sufficient contact between the cleaning wastewater containing formaldehyde and the activated carbon plate 16.

[0026] It should be noted that a sealing gasket is installed at the bottom of the sealing plate 17, and the sealing plate 17 is fixed to the top of the purification box 11 by bolts, so that the sealing plate 17 and the purification box 11 are sealed to prevent formaldehyde vapor from leaking from the gap between the sealing plate 17 and the purification box 11.

[0027] Further, such as Figure 4 As shown, an inclined guide plate 20 is installed at the bottom of the purification box 11, and the bottom of the limit seat 19 is set on the guide plate 20. In actual use, the bottom surface of the activated carbon plate 16 corresponds to the top surface of the guide plate 20, so that the cleaning water entering the purification box 11 can flow along the guide plate 20 to the discharge port 13 and contact the activated carbon plates 16 one by one.

[0028] A second valve 9 is installed on one end of the liquid inlet pipe 2 away from the delivery pump 1 and on one end of the liquid outlet pipe 3 away from the delivery pump 1 .

[0029] Specifically, during use, when the formaldehyde pumping and feeding device needs to be maintained, the first valve 6 is closed and then the second valve 9 is opened. At this time, clean water is introduced from the water inlet pipe 10. The clean water will flow to the purification box 11 under the action of the water pump 7, and clean the inner wall of the pipeline and the delivery pump 1. Then, the water that flushes the inner wall of the pipeline and the delivery pump 1 will enter the purification box 11, and the activated carbon plate 16 will adsorb the formaldehyde contained in the water to ensure the safe discharge of the cleaning water. During the entire cleaning process, since formaldehyde detectors 12 are installed on the liquid inlet pipe 2 and the liquid outlet pipe 3, the formaldehyde content in the liquid inlet pipe 2 and the liquid outlet pipe 3 can be detected, so as to judge the degree of cleaning, to ensure that the formaldehyde content therein is at a safe value when the formaldehyde pumping and feeding device is disassembled for maintenance.

[0030] In order to further facilitate the disassembly of the formaldehyde pumping feeding device during maintenance, the delivery pump 1 is connected to the liquid inlet pipe 2 and the liquid outlet pipe 3 through a flange, the liquid inlet pipe 2 is connected to the purification box 11 through a flange, and the end of the connecting pipe 8 is connected to the water pump 7 and the liquid outlet pipe 3 through a flange.
