Description

Technical Field

[0001] The present application relates to the technical field of quartz sand processing, and in particular to a slurry dehydration device applied to quartz sand. Background Art

[0002] Quartz sand needs to be washed during the production process. The sand washing process is to flush the quartz sand with a large amount of liquid water to remove the soil mixed in the quartz sand. After sand washing, the mud needs to be dehydrated. The dehydration process is used to filter out the water mixed in the quartz sand as soon as possible. Existing mud dehydration equipment usually uses a water squeezing cylinder to squeeze the quartz sand on the conveying filter bag so that the water is separated from the quartz sand and flows out through the fine mesh holes on the conveying filter bag. However, after being squeezed by the water squeezing cylinder, the quartz sand will be spread flat on the conveying filter bag. At this time, when the water squeezing cylinder is operated for the second time, the thickness of the quartz sand is relatively thin, and the water cannot be effectively squeezed out of the quartz sand. Therefore, the dehydration efficiency is low. Utility Model Content

Figure 5A schematic diagram of the local structure of the high-pressure gas cylinder provided in the embodiment of the present application. The slurry dewatering device 100 applied to quartz sand includes a dewatering box 110, which is used to support and set up components such as a conveying filter bag 122, a lifting component 141 and a high-pressure gas cylinder 123. At the same time, a relatively closed space can be formed inside the dewatering box 110 to prevent the water separated from the quartz sand slurry from leaking and playing the role of collecting water. A filter bag conveyor 120 is horizontally arranged in the dewatering box 110. The filter bag conveyor 120 is a prior art, which is used to convey the quartz sand slurry to be filtered. The output end of the filter bag conveyor 120 extends to one side of the dewatering box 110 and is connected to a scraper plate 113. After the quartz sand slurry on the filter bag conveyor 120 is filtered, it will be conveyed to the receiving component outside the dewatering box 110. The scraper plate 113 is used to scrape off the quartz sand adhering to the conveying filter bag 122. The scraper plate 113 can be set with reference to the prior art. The filter bag conveyor 120 includes two symmetrically arranged driving wheels 121, on which a conveying filter bag 122 is commonly wound. The driving wheels 121 drive the conveying filter bag 122 to rotate to achieve the function of conveying materials. As is well known in the art, the conveying filter bag 122 has water filtering holes. The conveying filter bag 122 is located above the two driving wheels 121 and is the first filter bag 122a, and is located below the two driving wheels 121 and is the second filter bag 122b. For the convenience of description, the conveying filter bag 122 is divided into the first filter bag 122a and the second filter bag 122b. However, it should be noted that the first filter bag 122a and the second filter bag 122b are an integrated structure, and their positions will change accordingly as the conveying filter bag 122 rotates. A high-pressure gas cylinder 123 is arranged between the first filter bag 122a and the second filter bag 122b, and a high-pressure gas groove 123a is opened on the outer side of the high-pressure gas cylinder 123. The high-pressure gas groove 123a extends along the axial direction of the high-pressure gas cylinder 123. The high-pressure gas cylinder 123 is connected to a high-pressure air pump to further spray high-pressure gas from the high-pressure gas groove 123a to the second filter bag 122b to blow off the sediment adhering to the above-mentioned water filter holes at the conveying filter bag 122. A feed trough 130 is provided at the top of the dewatering box 110, and the bottom of the feed trough 130 extends to the top of the input end of the filter bag conveyor 120. The quartz sand slurry is added from the feed trough 130 and falls onto the filter bag conveyor 120. An extrusion dewatering component 140 is provided at the top of the first filter bag 122a. The extrusion dewatering component 140 is used to squeeze the slurry on the conveying filter bag 122 to complete rapid drainage. The extrusion dewatering component 140 includes a lifting component 141, and the lifting component 141 is used to drive the water squeezing cylinder 142 and the sand gathering component 143 to rise and fall. A plurality of water squeezing cylinders 142 and a plurality of sand gathering components 143 are arranged at intervals at the bottom of the lifting component 141. The water squeezing cylinder 142 is a prior art. After the water squeezing cylinder 142 is driven to fall by the lifting plate 141a, the water squeezing cylinder 142 squeezes the quartz sand slurry on the conveying filter bag 122 and rolls.The sand gathering component 143 includes two symmetrically arranged sand gathering plates 143a, and a sediment flow channel 143b with a gradually narrowing path is formed between the two corresponding sand gathering plates 143a. During operation, the bottom end of the sand gathering plate 143a will abut against the top of the conveying filter bag 122, and then the material on the conveying filter bag 122 will gradually gather toward the middle when passing through the sediment flow channel 143b, so that the quartz sand slurry on the conveying filter bag 122 has a sufficient thickness, so that the water squeezing cylinder 142 behind it can effectively squeeze out the water in the quartz sand slurry.

[0022] As can be seen from the above, in the embodiment of the present application, the quartz sand slurry is conveyed by setting a filter bag conveyor 120, and an extrusion and dehydration component 140 is set at the same time. The extrusion and dehydration component 140 includes a lifting component 141, a water squeezing cylinder 142 and a sand gathering component 143. During operation, after the lifting component 141 drives the water squeezing cylinder 142 and the sand gathering component 143 to a suitable height, the water squeezing cylinder 142 and the sand gathering component 143 cooperate with each other to work. The sand gathering component 143 can gather the quartz sand slurry on the conveying filter bag 122 to a certain height so that it has a certain thickness, so that the water squeezing cylinder 142 can effectively squeeze the quartz sand slurry during operation, and further can efficiently discharge water from the quartz sand slurry. The present application also provides a high-pressure gas cylinder 123, and the high-pressure gas tank 123a can spray high-pressure gas to the second filter bag 122b to blow off the mud and sand adhering to the conveying filter bag 122, thereby avoiding the water filtering effect being affected by the blockage of the water filtering holes on the conveying filter bag 122.

[0023] In some embodiments, a discharge port 131 is provided at one side of the bottom of the feed chute 130, and triangular baffle plates 132 are fixedly connected to both sides of the discharge port 131. In the embodiment of the present application, the baffle plates 132 are provided to prevent the quartz sand slurry falling from the feed chute 130 onto the conveying filter bag 122 from falling along both sides of the conveying filter bag 122. At the same time, the baffle plates 132 also have a certain gathering effect, which can make the quartz sand slurry have a certain initial thickness after falling onto the conveying filter bag 122, so as to facilitate the subsequent squeezing operation of the squeezing cylinder 142.

[0024] In some embodiments, a support plate 124 is provided at the bottom of the first filter bag 122a, the support plate 124 is fixed to the inner wall of the dehydration box 110, and the top of the support plate 124 abuts against the bottom of the first filter bag 122a. In the embodiment of the present application, the support plate 124 is provided to provide a fulcrum for the bottom of the first filter bag 122a, thereby further improving the working efficiency and stability of the extrusion cylinder.

[0025] In some embodiments, a flushing device is included, and the bottom of the dewatering box 110 is contracted to form a discharge cone 111. A clean water pipe 112 is connected to one side of the dewatering box 110, and the clean water pipe 112 extends to the top of the discharge cone 111. In the embodiment of the present application, the flushing device is provided to flush the discharge cone 111 to flush out the silt adhering to the discharge cone 111.

[0026] In some embodiments, the lifting component 141 includes a lifting plate 141a, the water squeezing cylinder 142 and the sand collecting component 143 are both connected to the bottom of the lifting plate 141a, the top of the lifting plate 141a is connected to the inner wall of the dehydration box 110 through the telescopic rod 141b, and at least two limiting rods 141c are provided on the top of the lifting plate 141a, and the limiting rods 141c extend to the top of the dehydration box 110 through the limiting holes. The embodiment of the present application provides a specific setting method of the lifting plate 141a, the telescopic rod 141b is used to drive the lifting plate 141a to lift, and the limiting rod 141c limits the movement of the lifting plate 141a in the horizontal direction to ensure the stability of the lifting plate 141a during the activity.

[0027] In some embodiments, the water squeezing cylinder 142 and the sand gathering component 143 are both connected to the bottom of the lifting plate 141a through the elastic support member 144. In the embodiment of the present application, through the above arrangement, when the water squeezing cylinder 142 squeezes the quartz sand slurry, if the thickness of the quartz sand slurry is too large, the elastic support member 144 will shrink after being compressed, otherwise the elastic support member 144 pushes the water squeezing cylinder 142 to fall, thereby realizing the adaptive adjustment of the water squeezing cylinder 142. It should be noted that the elastic support member installed on the water squeezing cylinder 142 and the elastic support member 144 connected to the sand gathering component 143 can select elastic members with the same or different elastic coefficients according to actual use conditions.
