Description

Technical Field

[0001] The utility model belongs to the technical field of galvanizing sludge drying, in particular to a spiral galvanizing sludge drying device. Background Art

[0002] Galvanizing sludge is a byproduct of the galvanizing process. Generally speaking, galvanizing sludge is mainly composed of zinc, iron, lead and other elements. Among them, zinc is the main component of galvanizing sludge, and the content of iron and lead is relatively small. At the same time, galvanizing sludge may also contain a small amount of copper, nickel, chromium and other elements. Galvanizing sludge contains a large amount of heavy metal elements, which are harmful to the environment and health. If galvanizing sludge is handled at will, the heavy metal elements in it will penetrate into the soil, causing soil pollution and affecting plant growth and soil ecological environment. If galvanizing sludge is discharged into water bodies, it will lead to the deterioration of water quality and affect aquatic organisms and human health.

[0003] The galvanizing sludge needs to be dried before being treated. The existing technology is to directly dry it without dehydrating the galvanizing sludge before drying, and the drying efficiency is low.

[0004] The utility model designs a spiral galvanized sludge drying device to solve the above problems. Utility Model Content

[0005] Based on this, it is necessary to provide a spiral galvanized sludge drying equipment to address the problems existing in the current mask system. The present invention controls the rotation of the elastic spiral blades to stir the galvanized sludge, controls the rotation of the drum to make the galvanized sludge therein tumble, and controls the retraction of the elastic spiral blades to squeeze the galvanized sludge. The above three methods can achieve rapid drying of the galvanized sludge.

[0006] The above purpose is achieved through the following technical solutions:

[0007] A spiral galvanized sludge drying device, comprising:

[0008] The drum is used for loading galvanized sludge, and the outer circumferential surface of one end of the drum is provided with evenly distributed drainage holes.

[0009] The elastic spiral blade is installed in the drum through the mounting shaft for stirring and transporting galvanized sludge.

[0010] The motor has an output shaft fixedly connected to a mounting main shaft on which the elastic spiral piece is mounted, and provides power for the rotation and compression of the elastic spiral piece.

[0011] The regulating mechanism connects the motor and the drum to control the rotation of the drum.

[0012] In one of the embodiments, a feeding port is formed on the outer circumferential surface of one end of the drum close to the motor, and an arc-shaped feeding port sealing plate is detachably mounted on the feeding port by bolts.

[0013] A discharge port is formed on the outer circumferential surface of the drum at one end away from the motor, and an arc-shaped discharge port sealing plate is detachably mounted at the discharge port through bolts.

[0014] In one of the embodiments, a reciprocating screw is fixedly mounted on one end of the mounting spindle close to the motor and located inside the drum.

[0015] The transmission sleeve is installed in the drum by sliding in cooperation with the reciprocating screw rod, and the transmission sleeve and the drum are connected by sliding; the side of the transmission sleeve facing away from the motor is fixedly installed with a pressure plate by three circumferentially evenly distributed transmission rods, and the pressure plate is fixedly connected to one end of the elastic spiral sheet.

[0016] In one of the embodiments, a plurality of guide slide bars are evenly and fixedly installed on the inner circumferential surface of the drum near one end of the motor; a plurality of guide slide grooves are evenly opened on the outer circumferential surface of the transmission sleeve; the guide slide grooves correspond to the guide slide bars installed in the drum one by one and are connected in a sliding manner.

[0017] In one of the embodiments, a water receiving box is installed directly below the connected drum, and the water receiving box is located on the workbench.

[0018] In one embodiment, two regulating mechanisms are symmetrically installed at both ends of the drum.

[0019] The regulating mechanism includes a fixed ring, a planetary gear, a sun gear, a fixing bolt, a mounting shaft, a fixing plate, and a gear ring, wherein the sun gear is fixedly mounted on the mounting spindle, and the fixing plate is mounted on the workbench through a fixing bracket; three mounting shafts evenly distributed in the circumferential direction are fixedly mounted on the fixing plate; a planetary gear is rotatably mounted on each mounting shaft; the three planetary gears are meshed with the sun gear; the fixed ring is fixedly mounted on the end face of the drum through fixing bolts, and a gear ring is fixedly mounted on the inner circumferential surface of the fixed ring, and the gear ring is meshed with the three planetary gears.

[0020] In one of the embodiments, the fixed disk is rotatably mounted on a fixed bracket, and a second limiting bolt for limiting whether the fixed disk can rotate relative to the fixed bracket is detachably mounted between the fixed disk and the fixed bracket; a first limiting bolt for limiting whether the fixed ring can rotate relative to the fixed bracket is mounted between the fixed ring and the fixed bracket.

[0021] In one embodiment, the diameter of the drainage hole is 5 mm.

[0022] The beneficial effects of the utility model are:

[0023] 1. Control the motor to work. The motor can drive the installation main shaft to rotate. The rotation of the installation main shaft drives the elastic spiral piece to rotate, stir the galvanized sludge in the drum, and increase the drying efficiency of the galvanized sludge.

[0024] 2. When the control motor is working, the motor drives the installation spindle to rotate, and the installation spindle will drive the drum to rotate through the regulating mechanism, and the rotation speed of the drum is lower than the rotation speed of the elastic spiral sheet; by controlling the rotation of the drum, the galvanized sludge in the drum is rolled, thereby increasing the drying efficiency of the galvanized sludge.

[0025] 3. When the control motor is working, the control mechanism can be adjusted so that the drum is locked. The installed main shaft will only drive the elastic spiral piece to rotate. The elastic spiral piece can be used to transport the galvanized objects after drying in the drum and unload the galvanized sludge after drying.

[0026] 4. In the process of controlling the rotation of the installation spindle, the installation spindle will drive the reciprocating screw to rotate, and the rotation of the reciprocating screw will drive the transmission sleeve to slide back and forth along the axis of the drum. The sliding of the transmission sleeve drives the pressure plate to slide through the transmission rod, and the pressure plate drives the elastic spiral piece to retract and contract. During the retraction process, the galvanized sludge in the drum will be squeezed to squeeze out the moisture in the galvanized sludge and increase the drying effect.

[0038] like Figure 1-Figure 7As shown, a spiral galvanized sludge drying equipment includes: a drum 2, used for loading galvanized sludge, and the outer cylindrical surface of one end of the drum 2 is provided with evenly distributed drainage holes 21; an elastic spiral piece 6, installed in the drum 2 through an installation main shaft 7 for stirring and transporting the galvanized sludge; a motor 1, whose output shaft is fixedly connected to the installation main shaft 7 on which the elastic spiral piece 6 is installed, providing power for the rotation and compression of the elastic spiral piece 6; a regulating mechanism 5, connecting the motor 1 and the drum 2, and controlling the rotation of the drum 2.

[0039] The motor 1 is controlled to work, and the motor 1 can drive the installation main shaft 7 to rotate. The rotation of the installation main shaft 7 drives the elastic spiral piece 6 to rotate, so as to stir the galvanized sludge in the drum 2 and increase the drying efficiency of the galvanized sludge.

[0040] When the motor 1 is controlled to work, the motor 1 drives the installation spindle 7 to rotate, and the installation spindle 7 drives the drum 2 to rotate through the regulating mechanism 5, and the rotation speed of the drum 2 is less than the rotation speed of the elastic spiral sheet 6; by controlling the rotation of the drum 2, the galvanized sludge in the drum 2 is rolled, thereby increasing the drying efficiency of the galvanized sludge.

[0041] After drying is completed, the motor 1 is controlled to work and the regulating mechanism 5 is adjusted so that the drum 2 is locked. The main shaft 7 is installed to only drive the elastic spiral piece 6 to rotate. The elastic spiral piece 6 is used to transport the dried galvanized objects in the drum 2 and unload the galvanized sludge after drying.

[0042] In a further embodiment, Figure 4 As shown, a feeding port is provided on the outer circumferential surface of the drum 2 near the end of the motor 1, and an arc-shaped feeding port sealing plate 22 is detachably installed at the feeding port by bolts.

[0043] like Figure 4 As shown, a discharge port is formed on the outer circumferential surface of the drum 2 at one end away from the motor 1, and an arc-shaped discharge port sealing plate 23 is detachably mounted at the discharge port by bolts.

[0044] The function of the feeding port is to add galvanized sludge into the drum 2; the function of the feeding sealing plate is to block the feeding port to prevent the galvanized sludge from flowing out of the feeding port during the rotation of the drum 2.

[0045] The function of the discharge port is to discharge the dried galvanized sludge in the drum 2; after drying, the motor 1 is controlled to work and the regulating mechanism 5 is adjusted so that the drum 2 is locked, and the installation main shaft 7 will only drive the elastic spiral piece 6 to rotate, and the elastic spiral piece 6 will transport the dried galvanized sludge to the discharge port for discharge.

[0046] The function of the discharge sealing plate is to block the discharge port to prevent the galvanized sludge that is not completely dried from flowing out of the discharge port during the rotation of the drum 2, thereby affecting the drying effect.

[0047] In a further embodiment, Figure 3 As shown, a reciprocating screw rod 71 is fixedly mounted on one end of the mounting main shaft 7 close to the motor 1 and located inside the drum 2 .

[0048] like Figure 3 , 5 As shown, the transmission sleeve 9 is installed in the drum 2 by sliding in cooperation with the reciprocating screw 71, and the transmission sleeve 9 and the drum 2 are connected by sliding; the side of the transmission sleeve 9 facing away from the motor 1 is fixedly installed with the pressure plate 8 by three circumferentially evenly distributed transmission rods 10, and the pressure plate 8 is fixedly connected to one end of the elastic spiral sheet 6.

[0049] In the process of controlling the rotation of the installation main shaft 7, the installation main shaft 7 will drive the reciprocating screw 71 to rotate. The rotation of the reciprocating screw 71 will drive the transmission sleeve 9 to slide back and forth along the axis of the drum 2. The transmission sleeve 9 slides through the transmission rod 10 to drive the pressure plate 8 to slide. The pressure plate 8 will drive the elastic spiral piece 6 to retract and retract. During the retraction process, the galvanized sludge in the drum 2 will be squeezed to squeeze out the moisture in the galvanized sludge, thereby increasing the drying effect.

[0050] In a further embodiment, Figure 4 , 5 As shown, a plurality of guide slides 24 are evenly fixedly installed on the inner circumferential surface of the drum 2 near one end of the motor 1; a plurality of guide slots 91 are evenly opened on the outer circumferential surface of the transmission sleeve 9; the guide slots 91 correspond to the guide slides 24 installed in the drum 2 one by one and are connected in a sliding fit. The cooperation between the guide slides 24 and the guide slots 91 can increase the sliding stability of the transmission sleeve 9 and the pressure plate 8; at the same time, it can limit the rotation of the transmission rod 10; and ensure that the reciprocating screw 71 can smoothly drive the transmission sleeve 9 to slide back and forth in the drum 2.

[0051] In a further embodiment, Figure 1 , 2 As shown, a water receiving box 4 is installed directly below the connected drum 2, and the water receiving box 4 is located on the workbench. The water squeezed out of the galvanized sludge will flow out from the drain holes 21 opened on the drum 2 and fall into the water receiving box 4 for collection, so as to prevent the drained water from falling on the ground and polluting the environment.

[0052] In a further embodiment, Figure 1 , 2 As shown, two regulating mechanisms 5 are symmetrically installed at both ends of the drum 2.

[0053] like Figure 6 , 7As shown, the regulating mechanism 5 includes a fixed ring 51, a planetary gear 52, a sun gear 53, a fixing bolt 55, a mounting shaft 56, a fixing plate 58, and a gear ring 59, wherein the sun gear 53 is fixedly mounted on the mounting spindle 7, and the fixed plate 58 is mounted on the workbench through a fixing bracket 3; three mounting shafts 56 evenly distributed in the circumferential direction are fixedly mounted on the fixed plate 58; a planetary gear is rotatably mounted on each mounting shaft 56; the three planetary gears are meshed with the sun gear 53; the fixed ring 51 is fixedly mounted on the end surface of the drum 2 by fixing bolts 55, and a gear ring 59 is fixedly mounted on the inner circumferential surface of the fixed ring 51, and the gear ring 59 is meshed with the three planetary gears.

[0054] When the fixed plate 58 is stationary relative to the fixed bracket 3, the rotation of the mounting main shaft 7 will drive the sun gear 53 to rotate, the rotation of the sun gear 53 will drive the three planetary gears 52 to rotate, the rotation of the planetary gear 52 will drive the gear ring 59 to rotate, the rotation of the gear ring 59 will drive the fixed ring 51 to rotate, the rotation of the fixed ring 51 will drive the drum 2 to rotate, and the galvanized sludge in the drum 2 will be tumbled by controlling the rotation of the drum 2, thereby increasing the drying efficiency of the galvanized sludge.

[0055] In a further embodiment, Figure 6 , 7 As shown, the fixed plate 58 is rotatably installed on the fixed bracket 3, and a second limiting bolt 57 is detachably installed between the fixed plate 58 and the fixed bracket 3 to limit whether the fixed plate 58 rotates relative to the fixed bracket 3; a first limiting bolt 54 is installed between the fixed ring 51 and the fixed bracket 3 to limit whether the fixed ring 51 rotates relative to the fixed bracket 3.

[0056] After drying is completed, the second limiting screw is loosened so that the fixed plate 58 can rotate relative to the fixed bracket 3, and the first limiting bolt 54 is tightened to lock the fixed ring 51 and the fixed bracket 3, that is, the rotation of the drum 2 is locked. At this time, the installation spindle 7 is controlled to rotate, and the installation spindle 7 will only drive the elastic spiral piece 6 to rotate. The elastic spiral piece 6 can realize the transportation of the dried galvanized objects in the drum 2, which is used for unloading the galvanized sludge after drying.

[0057] In a further embodiment, the diameter of the drainage hole 21 is 5 mm, which can ensure the drainage effect without being blocked.

[0058] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the attached claims.
