Description

Technical Field

[0001] The utility model relates to the field of material transportation, in particular to a material transportation tool used in a xylose crystallization separation process. Background Art

[0002] In the traditional xylose production process, the transportation of xylose crystals separated by centrifuges is usually done by a coverless rectangular cabinet trolley. Since the centrifuge discharge port is at the bottom of the device, in order to enable the trolley to move below the discharge port to receive the material, the height of the trolley hopper side wall must be less than the height of the lower end of the discharge port. When discharging the material from the discharge port, some xylose crystals will splash onto the ground, causing waste. In addition, the space available for operators at the discharge port is small, making it inconvenient to clean the ground.

[0003] In addition, xylose crystals are prone to spillage during transportation and need to be manually unloaded by operators, which is labor-intensive, time-consuming, and poses a risk of spillage and contamination.

[0004] In view of the problems existing in the above-mentioned prior art, the utility model designs a material transportation tool applied to the xylose crystallization separation process to overcome the above-mentioned defects. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a material transportation tool used in the xylose crystallization separation process, which can effectively reduce the labor intensity of operators, shorten the transportation time, and reduce the risk of material leakage during the transportation process.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a material transport tool used in a xylose crystallization separation process, comprising a hopper, on which a blocking cover capable of covering the upper end surface of the hopper is installed;

[0007] The blocking cover comprises a guide plate and two cover plates, the two sides of the guide plate are respectively connected to the two cover plates, one end of the guide plate is hinged to the side wall of the hopper, and the other end of the guide plate is provided with an arc surface that can contact the outer wall and the lower end surface of the centrifuge discharge port;

[0008] A connection chain for limiting the rotation of the blocking cover is installed at one end of the hopper, one end of the connection chain is rotatably installed on the hopper, and the other end of the connection chain is rotatably installed on the side wall of the cover plate.

[0009] Preferably, a discharge door is rotatably mounted on one end of the hopper away from the connecting chain, and the discharge door is rotatably mounted on the side wall of the hopper.

[0010] Preferably, a material discharge slope surface inclined downward along the direction of the discharge door is provided on the inner wall of the lower end of the hopper, the upper end of the discharge door is rotatably mounted on the hopper, and the lower end of the discharge door can rest on the material discharge slope surface.

[0011] Preferably, a locking block is installed at one end of the hopper on which the discharge door is installed, and one end of the locking block is rotatably installed on the hopper, and the discharge door can rest against a surface of the locking block that contacts the hopper.

[0012] Preferably, a plurality of self-locking universal wheels are provided at the bottom of the hopper.

[0013] Preferably, a push handle is installed at the end of the hopper where the discharge door is not installed.

[0014] Preferably, the inner wall diameter of the arc-shaped surface is slightly larger than the outer diameter of the discharge port of the centrifuge.

[0015] Preferably, the angle between the material discharge slope and the bottom surface is 20°-40°.

[0016] Preferably, two ends of the connecting chain are detachably mounted on the hopper and the blocking cover respectively.

[0017] The beneficial effects of the utility model are as follows:

[0018] 1. The utility model installs a baffle cover on the hopper, arranges a guide plate on the baffle cover, and arranges an arc surface that can contact the outer wall and the lower end surface of the discharge port of the centrifuge at the end of the guide plate that is not connected to the hopper. During transportation, the baffle cover can cover the upper end of the hopper to prevent the xylose crystals from spilling, and during loading, the guide plate can lean against the discharge port to prevent the xylose crystals from splashing, effectively preventing the xylose crystals from falling or spilling during loading and transportation, thereby reducing the waste of xylose crystals and the pollution to the environment.

[0019] 2. The utility model has a discharge door installed at one end of the hopper, and also has a locking block that can limit the rotation of the discharge door. When unloading, the locking block is rotated to release the limit of the discharge door.

[0024] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings.

[0025] like Figure 1-2 The material transport tool shown is used in the xylose crystallization separation process, including a hopper 6, on which is installed a blocking cover that can cover the upper end surface of the hopper 6. Compared with an uncovered cabinet-type trolley, xylose crystals are less likely to spill during transportation, thereby reducing the loss of xylose crystals during transportation and reducing waste.

[0026] The utility model blocking cover comprises a guide plate 2 and two cover plates 3, the two sides of the guide plate 2 are respectively connected with the two cover plates 3, one end of the guide plate 2 is hinged with the side wall of the hopper 6, and the other end of the guide plate 2 is provided with an arc surface 11 that can contact the outer wall and lower end surface of the centrifuge discharge port 1; the inner wall diameter of the arc surface 11 is slightly larger than the outer diameter of the centrifuge discharge port 1, and the arc surface 11 of the guide plate 2 can be blocked at the discharge port 1 when the centrifuge is unloading, and the inclined guide plate 2 surrounds the discharge port 1, and only leaves an outlet for the discharge of xylose crystals near the direction of the hopper 6, which effectively avoids the situation that the xylose crystals splash around and fall on the bottom surface when unloading, which is inconvenient to clean up. It reduces the pollution to the environment and the waste of xylose crystals.

[0027] One end of the hopper 6 of the utility model is equipped with a connecting chain 4 for limiting the rotation of the blocking cover, one end of the connecting chain 4 is rotatably mounted on the hopper 6, and the other end of the connecting chain 4 is rotatably mounted on the side wall of the cover plate 3. When the hopper 6 is loaded, the operator needs to flip the blocking cover upward until the connecting chain 4 is tightened to limit the rotation of the blocking cover.

[0028] Specifically, after the cover is fully unfolded, it forms a certain angle with the horizontal plane. The xylose crystals falling from the discharge port 1 of the centrifuge will slide along the guide plate 2 on the cover into the hopper 6, realizing rapid loading. The labor intensity of the operator is reduced. After the loading is completed, the cover is rotated to cover the upper end of the hopper 6. During the rotation process, the xylose crystals attached to the guide plate 2 and the two cover plates 3 will fall into the hopper 6 due to their own gravity.

[0029] The two ends of the connecting chain 4 of the utility model are detachably mounted on the hopper 6 and the cover, respectively. The opening angle of the cover can be adjusted by replacing the connecting chain 4 of different lengths. A plurality of self-locking universal wheels 7 are provided at the bottom of the hopper 6. When loading, the self-locking universal wheels 7 are locked to prevent the hopper 6 from being displaced during the loading process, causing the xylose crystals to scatter and cause pollution and waste. A cart handle 5 is installed at one end of the hopper 6 where the discharge door 10 is not installed, so that the operator can push the transport tool to move.

[0030] Specifically, before loading the xylose crystals, the cover is first unfolded, and then the transport vehicle is pushed to move toward the discharge port 1 of the centrifuge, so that the inner wall of the arc surface 11 of the guide plate 2 contacts the discharge port 1 of the centrifuge. After the parking position of the transport vehicle is determined, the self-locking universal wheel 7 is locked, and the discharge port 1 can be opened to start loading the xylose crystals;

[0031] After the xylose crystals are loaded, the hopper 6 is pushed along the direction in which the baffle cover is expanded until the entire transport vehicle leaves the discharge port 1, and then the baffle cover is flipped in the opposite direction so that the two cover plates 3 are in contact with the upper end surface of the hopper 6. After the baffle cover is completely covered on the hopper 6, the xylose crystals are transported to the designated location.

[0032] The end of the hopper 6 of the utility model away from the connecting chain 4 is rotatably mounted with a discharge gate 10, and the discharge gate 10 is rotatably mounted on the side wall of the hopper 6. The inner wall of the lower end of the hopper 6 is provided with a discharge slope 8 that is inclined downward along the direction of the discharge gate 10, and the angle between the discharge slope 8 and the bottom surface is 20°-40°. The upper end of the discharge gate 10 is rotatably mounted on the hopper 6, and the lower end of the discharge gate 10 can be against the discharge slope 8. A locking block 9 is installed at one end of the hopper 6 where the discharge gate 10 is mounted, and one end of the locking block 9 is rotatably mounted on the hopper 6, and the discharge gate 10 can be against the side of the locking block 9 that contacts the hopper 6.

[0033] Specifically, when loading xylose, the locking block 9 is in a locked state. The end of the locking block 9 that is not mounted on the hopper 6 in the locked state abuts against the side of the discharge door 10 away from the cart handle 5. The discharge door 10 is always kept in a vertical state under the common limit of the discharge slope 8 and the locking block 9, and the end of the hopper 6 away from the cart handle 5 is closed to prevent the leakage of xylose crystals during transportation.

[0034] Specifically, after the xylose crystals are transported to the designated location, the locking block 9 is rotated so as not to contact the discharge door 10, and the locking state is released. The xylose crystals loaded in the hopper 6 push the discharge door 10 open due to their own gravity, and then slide out of the hopper 6 along the discharge slope 8 to achieve unloading. The labor intensity of the operator is reduced and the unloading speed is increased. After unloading is completed, the locking block is rotated to the locking state, the discharge door 10 is locked, and the end of the hopper 6 is closed.

[0035] It should be understood that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the protection scope of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the protection scope defined by the claims attached to this application.
