Description

Opening and closing device and biomass processing equipment

The invention relates to an opening and closing device and a processing device, in particular to an opening and closing device and a biomass processing device for hydrothermal treatment of biomass.

Conventional use of high-temperature steam for the treatment of kitchen waste or biomass waste, mostly using horizontal cooking pots, such as the Republic of China Announcement No. I 221788, I 281496, M 346469 patent, No. 96112929, No. 96125706 The Japanese Patent No. 3,085,543, the application of the Japanese Patent No. 2008-55285, the Chinese Patent No. CN 101184560A, the disclosure of the US Patent No. 2009/0314700 A1, etc., all of which have horizontal stirring shafts and multiple sets of stirring. The blade, the feed port is located above the cooking pot, and the discharge port is located below the cooking pot.

Since the high temperature steam is used at temperatures above 120 ° C and the pressure in the cooking pot exceeds 1 atmosphere, it must be sealed to maintain the internal high temperature. In order to balance the rapid feeding/discharging and sealing to withstand high pressure, conventional techniques mostly provide a large ball valve at the inlet/outlet to achieve the above functions. However, whether the kitchen waste or biomass waste has high moisture content, and the thickness of the solid matter is uneven, it is easy to cause the ball valve to block, or the fine particles enter the gap between the ball and the ball seat washer, causing wear and tear, resulting in leakage and poor sealing. , seriously affect the life of the ball valve, especially the bottom discharge port. In addition, large ball valves are not easy to manufacture, so they are quite expensive and are not conducive to the enlargement of processing equipment.

Japanese Patent No. 3089553 replaces the ball valve with a shutter type quick opening and closing mechanism, and drives the shutter to move laterally with a pneumatic or hydraulic cylinder to open or close the inlet/outlet. However, the sealing of the ram mechanism is not easy, and the sliding friction between the sealing gasket and the ram is easy to cause wear and shorten the service life; when using higher temperature steam (such as 230 ° C), higher pressure (such as 28.5 kg/cm ² ) is required. ), the thickness and weight of the shutter will increase a lot, it will become bulky and difficult to move, so it is not applicable.

Referring to Figures 2 and 3, in the present embodiment, the biomass is described by taking the kitchen waste as an example. Before the kitchen waste is subjected to the hydrothermal treatment operation, the internal opening and closing unit 6 and the external opening and closing unit 7 are first closed and closed. The two plates 61 are close to each other to block the passage 55. The cover 75 blocks the opening 56 and seals the sealing gasket 76 between the cover 75 and the third housing 53. The tongs 73 are combined into a ring shape to sandwich the cover 75 with the third housing 53. After the internal opening and closing unit 6 and the external opening and closing unit 7 confirm the closing, the kitchen waste is put into the cooking container 21 from the inlet 22 to be hydrothermally treated at a high temperature and a high pressure, and the discharging operation is performed after the hydrothermal treatment is completed. .

Referring to Figures 3 and 4, when unloading is performed, the two second driving sources 72 are first activated to move the two clamps 73 from the closed position shown in Figure 3 to the two sides to the open position as shown in Figure 4, and then As shown in FIG. 5, the third driving source 74 is activated to drive the cover 75 to descend and horizontally rotate to be detached from the opening 56 and not to block the discharge path of the passage 55. After the cover 75 reaches the open position, The two first driving sources 62 are further activated to move the two flat plates 61 from the closed position shown in FIG. 3 away from each other to the corresponding accommodating space 57 as shown in FIG. 4, and reach the opening 55. In the open position, the kitchen waste that has been hydrothermally treated in the cooking vessel 21 can be discharged through the passage 55. After the unloading is completed, the flat plate 61 and the cover 75 are closed in the reverse order of the opening operation, and the two clamps 73 are used to clamp and fix the cover 75 and the third casing 53.

It should be particularly noted that, in the process of closing or unloading, if pressure balance is required, steam can be introduced through the air inlet 54 to achieve pressure balance. In addition, in the embodiment, when the two flat plates 61 are located in the closed position, the sealing function can be selected, that is, the joint of the two flat plates 61 and the two flat plates 61 and the first and second joint portions 512. Between the joints of 521, there will be a gap 600 (since the gap between the two flat plates 61 and the joints of the first and second joint portions 512, 521 is too small, no further indication), so that the cooking waste is cooked during the hydrothermal treatment process. The pressure in the container 21 and the passage 55 is balanced by the flow through the slit 600.

The above-mentioned two plates 61 can only bear the pressure exerted by the weight of the kitchen waste in the closed position by any one or a combination of the above-mentioned air inlet 54 and the gap 600. There is a pressure from the high temperature vapor, so the thickness of the two plates 61 can be thinner and the service life is longer.

In addition, when the two flat plates 61 are in the closed position and have a sealing function, since the upper surface of the two flat plates 61 is in a high pressure state, the air can be introduced into the lower surface of the two flat plates 61 through the air inlet 54 to increase the pressure. It also achieves the purpose of balancing the pressure up and down.

The sealing cover 76 of the outer opening and closing unit 7 is provided with the sealing gasket 76. When the sealing member 75 blocks the opening 56, the sealing gasket 76 is sealed to the sealing cover 75 and the third housing. Between 53 , the external opening and closing unit 7 has a good sealing effect and can withstand the pressure of the high temperature steam from the cooking vessel 21; in addition, since the kitchen waste in the cooking vessel 21 is blocked by the two flat plates 61, Therefore, not only can the kitchen waste not fall out when the cover 75 is opened, but also the kitchen waste can be in direct contact with the cover 75 and the sealing gasket 76, in addition to avoiding the kitchen residue from blocking the opening action of the cover 75, The sealing gasket 76 can be prevented from being contaminated by the kitchen waste, so that the sealing effect is good and the service life of the sealing gasket 76 can be prolonged.

Referring to FIG. 6, a second preferred embodiment of the biomass processing apparatus of the present invention is substantially similar to the first preferred embodiment, except that the first and second bonding portions 512, 521 define only one of the first The accommodating space 57 on one side of the channel 55, and the inner opening and closing unit 6 includes only a flat plate 61 disposed in the accommodating space 57, and a second joint portion 521 disposed on the second housing 52. The first driving source 62 for driving the movement of the flat plate 61 is in the embodiment. Since there is only one flat plate 61, the gap between the flat plate 61 and the first and second joint portions 512 and 521 is 600. And the gap 600 of the flat plate 61 in the closed position to achieve the effect of pressure balance. Thereby, the functions as mentioned in the first preferred embodiment can be achieved as well as another alternative.

In summary, the biomass processing apparatus of the present invention blocks the falling of biomass through the internal opening and closing unit 6, and the external opening and closing unit 7 achieves a sealing function, and uses a double-layer opening and closing mechanism to extend the service life. Therefore, the object of the present invention can be achieved.
