Description of the invention (Background of the invention The present invention relates to a belt filter for dehydrating a gypsum slurry on an exhaust desulfurizer. A gypsum slurry applied to an exhaust desulfurizer The water device has changed from a centrifugal separation type to a basket-type air suction dehydration type, which uses a belt filter from the viewpoint of equipment cost, operation cost, maintenance cost, dewatering performance, etc. However, the fine impurities in the slurry are not Combustion of granular powder composed of carbon, calcium fluoride, silica, aluminum hydroxide, and iron hydroxide, as shown in Figure 2, on the surface of a dehydration block 201 to form a layer of particles with a thickness of about one to several millimeters 202 'makes the hollow The penetrability during suction is reduced, resulting in a decrease in dehydration performance. SUMMARY OF THE INVENTION The present invention is made from the viewpoint of the aforementioned situation, and one object thereof is to provide a belt filter, even if a granular layer is formed on a gypsum block. In order to achieve the above-mentioned object, according to the present invention, a belt type dehydrator is proposed, which comprises an empty dehydrator and a plurality of weirs. The drier sucks the gypsum slurry and dehydrates the slurry. The weir extends from the lower end to the gypsum block. The weir is located in the upper layer of the belt filter to disturb a layer of particles to form on the surface of the gypsum block. In the preferred embodiment, a clean water supply device can supply hot water, steam, or both hot water and steam to gypsum purple or gypsum blocks. The weir is preferably a material group containing rubber, plastic, bamboo, wood, and metal. 4- This paper scale applies to Chinese National Standard (CNS) A4 specifications (210X297 mm) Please read the I on the back side · Items and then fill in this page-4.

The weir preferably has a rectangular shape, and is preferably in the width direction of the branched filter. The device is suspended by a belt filter and is preferably equipped with a cleaning water supply device, and the surface is supplied with cleaning water. The temperature of the Λ Wild Stone Bone Cleaning Water should be the same as that of the gypsum mortar, or, more specifically, the temperature of the cleaning water can be about 10 times higher than the temperature of the slurry. 〇 is Ah. It is better to install it as a movable type. In this case, it is preferable to give the weir a function of detecting the position of Congshui by using a thickness sensor to automatically change its position. Therefore, according to the present invention, it can be assured that a belt-type filter is provided. Even if-a layer of granules is formed on the gypsum block, the filter can ensure the smart water performance. Similarly, in the application-weir-embodiment, the weir is already formed from the granular layer-position to intercept the water floating on the surface layer, and at the same time, the granular layer is disturbed, so that the moisture can be sucked and discharged by emptying. Avoid a stream of water on a surface. In addition, since a plurality of weirs are provided, the disturbance effect is quite large, and even if the characteristics of the gypsum slurry and the position of the particle layer are changed, any weir can determine the disturbance particle layer to ensure the tax performance.

In order to describe a belt type according to the present invention; a perspective view of a cross-sectional structure of the filter is described in detail in accordance with the present invention—S.-+ ·· Η, a belt filter will be implemented in the following with reference to the accompanying drawings Examples to illustrate. Ｍ 1 所 7 ′ of this embodiment ~ belt passer 1, gypsum material 2 forging head machine 3 is provided with a first empty box part 4 and a second empty box part 5, these two parts are used as Element composition-emptying dehydrator. Provide the __ oak wins conveyor belt 6 on the upper surfaces of the second and fourth heads 4 and 5 to contact it. This rubber belt 6 supports a circulating belt filter (cloth), as shown in Figure 3, on the surface of the rubber belt 6 A groove 2 1 is provided at a right angle to the direction of travel, and the structure of the groove 2 丨 includes a discharge hole 2 2 penetrating the rubber band 6, thereby generating air suction by the main components 4 and 5. The belt passer body 7 is gas-permeable, and the radon has a suitable strength to support the gypsum slurry 2 and a gypsum block 8. Moreover, this embodiment has a cleaning water supply device 9. This device is used to wash out the salt domain ions contained in gypsum ㈣2 to obtain high-quality (high-purity) gypsum. Furthermore, the belt filter of this embodiment has a weir 10. The weir 10 is a device that disturbs a granular layer formed on the surface of the gypsum block 8. The weir 10 extends from the lower end to the upper layer of the gypsum block 8 and three weirs 10 are provided in the longitudinal direction of the belt filter. In this sentence, the lower end of the weir 10 extends to the upper layer of the gypsum block 8 means that the weir has a sufficient length in the vertical direction, so that the lower end can disturb the granular layer of the gypsum block 8, thereby ensuring dehydration performance. -6 · This paper string scale applies to Chinese National Standard (CNS) A4 specifications (2 丨 0X297gf) Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs 5. Description of the invention (4) Weir 10 can be rubber, plastic, bamboo, wood , Metal, etc. 'but preferably made of rubber or synthetic rubber. A weir 10 having a rectangular shape is suspended by a supporting device (not shown) through the width direction of the belt filter 1. In the foregoing embodiment shown in FIG. 1, the gypsum slurry 2 is supplied from a supply forging machine 3 to the belt filter body 7, and is suction-filtered by the first empty box portion 4. The belt filter body 7 The gypsum block 8 obtained by the vacuum suction filtration is sent to the second vacuum box portion 5 through the rubber band 6. At this time, the cleaning liquid is supplied from the cleaning water supply device 9 to the gypsum block 8 at the same time. After the clean water is evacuated and filtered from the second evacuated tank portion 5, the moisture in the gypsum block 8 is removed by further evacuating it for a predetermined period of time. The dehydrated gypsum block 8 is conveyed toward a recovery conveyor n by the action of the rubber belt 6, and is self-contained; the container body 7 is separated 'and recovered by the recovery conveyor 1 丨. After the gypsum block 8 has been separated, the belt filter body 7 is cleaned with a belt eliminator cleaning device 12 and then sent to the slurry supply section again. The temperature of the cleaning water supplied from the self-cleaning water supply device 9 to the gypsum block 8 is equal to or greater than the temperature of the gypsum slurry, preferably 1 () higher than the temperature of the slurry. This is because when the temperature of the interstitial water in the gypsum block 8 rises, the viscosity and surface tension of the interstitial water are reduced, and the transfer resistance between the particles is reduced, thereby improving the permeability. At this time, the weir 10 extending to the upper layer of the gypsum block 8 is lower than the lower end to disturb the gypsum block 8 to the upper layer, including the formed particle layer. Thereby, the penetration of the gypsum block 8 is maintained, so that dehydration can be effectively performed. Similarly, weir 10 also contributes to the maintenance of exuding water. 3S 1 () _ The water seeping from the surface layer of the granule layer has been formed, and at the same time disturbing the granule layer, so that the water content from the empty paper is in accordance with Chinese national standards ( " Sis) A4 size π_χ ϋ take advantage of γ (Please read the precautions on the back before filling this page)
