[0049] The above scheme is adopted: by providing a power spring 803, when the cam 801 rotates, it can push the contact plate 802 to drive the drive frame 701 to move away from each other as a whole, and at the same time squeeze the power spring 803. Then, when the elastic force of the power spring 803 is released, it can push the two contact plates 802 and the drive frame 701 to move towards each other as a whole.

[0050] like Figure 2 and Figure 4 As shown, the bottom of the inner cavity of the mixing tank body 1 is slidably connected with a sealing baffle 9 located at the inner top of the scraper plate 501 , and the middle part of the outer end of the sealing baffle 9 is movably sleeved with the top of the installation shaft 605 .

[0052] like Figure 3 As shown, a sealing baffle ring 10 is provided in the inner cavity at the bottom of one side of the discharge pipe 4 , and a discharge valve group 11 located at the bottom of the sealing baffle ring 10 is movably installed in the inner cavity of the discharge pipe 4 .

[0053] By adopting the above solution, the top of the discharge valve group 11 can be blocked and sealed through the design of the sealing baffle ring 10 , and the top slope of the sealing baffle ring 10 can guide the material to the top of the discharge valve group 11 .

[0054] like Figure 3 and Fig.10 As shown, the discharge valve assembly 11 includes a first discharge valve column 1101, an electric telescopic rod 1102 and a second discharge valve column 1103;

[0055] The first discharge valve column 1101 is movably installed in the inner cavity of the discharge pipe 4 and is located below the sealing retaining ring 10. The electric telescopic rod 1102 is arranged in the middle of the bottom end of the inner cavity of the first discharge valve column 1101.

A slot located on the outside of the electric telescopic rod 1102 is opened on the outer side of the top of the first discharge valve column 1101.

[0056] The above scheme is adopted: through the slot design on the outer side of the top of the first discharge valve column 1101, when material is accumulated on the top of the first discharge valve column 1101, the electric telescopic rod 1102 can be operated to drive the second discharge valve column 1103 downward as a whole, so that the second discharge valve column 1103 releases the blockage of the slot on the top of the first discharge valve column 1101, and then the material on the top of the second discharge valve column 1103 will be discharged from the bottom of the discharge pipe 4 through the slot on the top of the first discharge valve column 1101.

[0057] like Fig.10 As shown, the inside of the discharge pipe 4 is provided with a hydraulic assembly 12 located outside the first discharge valve column 1101, and the hydraulic assembly 12 includes a sliding block 1201, a first hydraulic piston cylinder 1202, a piston rod 1203, a second connecting spring 1204 and an oil pipeline 1205;

[0058] The sliding block 1201 is arranged in the middle part of the outer side of the first discharge valve column 1101, the first hydraulic piston cylinder 1202 is arranged inside the discharge pipe 4 and is located on the outer side of the sliding block 1201, the piston rod 1203 is movably installed in the inner cavity of the first hydraulic piston cylinder 1202, the top end of the piston rod 1203 is fixedly connected to the bottom surface of the top end of the sliding block 1201, the piston rod 1203 is elastically connected to the inner wall of the first hydraulic piston cylinder 1202 through the second connecting spring 1204, and the interior of the stirring tank body 1 is provided with a clamping assembly 13 located on the outer side of the scraper plate 501, and the first hydraulic piston cylinder 1202 is connected to the outer end of the clamping assembly 13 through the oil pipeline 1205.

[0059] The above scheme is adopted: by providing a piston rod 1203, when the first discharge valve column 1101 is squeezed and pushed downward as a whole by the material transported by the spiral feeding mechanism 3, the sliding block 1201 can drive the piston rod 1203 to move downward as a whole, so that the hydraulic oil in the inner cavity of the first hydraulic piston cylinder 1202 enters the clamping assembly 13 through the oil pipeline 1205.

[0060] like Figure 5 and Figure 7 As shown, the clamping assembly 13 includes a second hydraulic piston cylinder 1301, a clamping piston rod 1302 and a clamping groove 1303;

[0061] The second hydraulic piston cylinder 1301 is fixedly installed inside the mixing tank body 1 and is located in the middle of the outer side of the scraper plate 501. The clamping piston rod 1302 is movably installed in the inner cavity of the second hydraulic piston cylinder 1301.

The other end of the oil pipeline 1205 is fixedly connected to the outer end of the second hydraulic piston cylinder 1301.

[0062] The above scheme is adopted: by providing a clamping piston rod 1302, when hydraulic oil enters the outer inner cavity of the second hydraulic piston cylinder 1301, and the clamping groove 1303 is directly opposite to the inner end of the clamping piston rod 1302, the hydraulic oil in the outer inner cavity of the second hydraulic piston cylinder 1301 can push the clamping piston rod 1302 toward each other until the inner end is completely inserted into the clamping groove 1303, and finally the fixing plate 703 and the scraper plate 501 can be raised and fixed as a whole.

[0063] The working principle and use process of the present invention:

[0064] First, when the stirring mechanism 2 rotates to stir the raw materials inside the stirring tank body 1 to synthesize dibenzoyl oxide, the spiral feeding mechanism 3 can be started to rotate. At this time, the spiral feeding mechanism 3 rotates, which can drive the cam 801 to rotate, so as to push the two contact plates 802 and the driving frame 701 to move in opposite directions as a whole. Then, the connecting arm 702 can be deflected to push the fixed plate 703 and the scraper plate 501 to move upward as a whole, and drive the spiral feeding mechanism 3 upward as a whole. Then, the material at the bottom of the stirring tank body 1 will enter the spiral feeding mechanism 3, and the spiral feeding mechanism 3 can continuously rotate and transport, which can push the first discharge valve column 1101 to move downward as a whole.

[0065] Afterwards, the first discharge valve column 1101 is lowered as a whole, so that the sliding block 1201 can push the piston rod 1203 to move downward as a whole. The hydraulic oil at the bottom of the inner cavity of the first hydraulic piston cylinder 1202 enters the second hydraulic piston cylinder 1301 through the oil pipeline 1205, so that the hydraulic pressure of the outer inner cavity of the second hydraulic piston cylinder 1301 becomes larger. When the fixing plate 703 and the scraper plate 501 are moved upward as a whole, the clamping groove 1303 and the clamping piston rod 1302 are facing each other. At this time, the clamping piston rod 1302 can be pushed toward each other by the hydraulic pressure to completely insert the inner end into the clamping groove 1303, and then the fixing plate 703 and the scraper plate 501 are extended upward as a whole.

[0066] Finally, when the scraper plate 501 is fixed upward as a whole, the mounting shaft 605 can be turned upward as a whole, so that the bottom inner wall is meshed and clamped with the top surface of the bevel gear rod 604, and then the spiral discharge mechanism 3 can be used to rotate the driving gear 601 as a whole to drive the driven gear rod 602 to rotate. At this time, the staggered semi-bevel gear 603 on one side of the driven gear rod 602 will mesh and rotate back and forth with the bottom of the semi-bevel gear 603, thereby driving the driven gear rod 602, the driving gear 601 and the scraper plate 501 to rotate as a whole. Finally, the scraper plate 501 rotates back and forth to scrape the material at the bottom of the mixing tank body 1 into the spiral discharge mechanism 3, and then discharge it through the discharge pipe 4.
