Description

Technical Field

[0001] The present invention belongs to the technical field of storage tanks, and particularly relates to a discharging device for an alginate storage tank. Background Art

[0002] Alginate is a type of polysaccharide widely present in various brown algae, and can be applied to various fields such as food, medicine, agriculture, printing and dyeing, papermaking, rubber, and machinery. The preparation of alginate specifically uses algae as raw materials, dissolves and extracts them with dilute alkali solution, and finally makes sodium salt. Alginate has strong water hydration and adhesiveness.

[0003] After the preparation of alginate is completed, it needs to be stored in a storage tank. When discharging is required, alginate is prone to caking into groups. Generally, a spiral conveyor frame inside is used to stir the material, but it is difficult for the spiral conveyor frame to stir the material in multiple directions, and the effect of stirring and dispersing the caked material is not good. Moreover, the inner wall of the storage tank is likely to adhere to the material, and there is a problem that the caked material is discharged without being effectively dispersed, which may cause the discharge port to be blocked. Summary of the Invention

[0004] In order to solve the problem that alginate is not effectively dispersed during discharging, the present invention provides a discharging device for an alginate storage tank.

[0005] Technical Solution: A discharging device for an alginate storage tank includes a bracket. The upper and lower parts of the bracket are respectively connected with a storage tank and a fixed tank. The upper part of the storage tank is provided with a feed port. The fixed tank is in a funnel shape and has a tubular part at the bottom. There is a rotating cylinder that is rotationally connected between the lower end of the storage tank and the upper end of the fixed tank and is driven by a driving mechanism. A circle of bent rods that fit the inner wall of the fixed tank is connected at intervals on the inner wall of the rotating cylinder. An annular frame is connected between the upper ends of all the bent rods. A pair of guide rods are connected to the inner top of the storage tank, and a circular plate that slides up and down is arranged between the two guide rods.

[0006] In addition, particularly preferably, the annular frame has a circle of cross bar parts arranged at radial intervals.

[0007] In addition, particularly preferably, the driving mechanism includes a toothed ring and a gear. A toothed ring is connected to the outer wall of the rotating cylinder. A gear driven by a servo motor is rotatably connected to the upper part of the bracket, and the gear meshes with the toothed ring.

[0008] In addition, particularly preferably, the discharging device for an alginate storage tank further includes a reduction box and a screw rod. The screw rod is rotatably connected to the inner top of the storage tank. The circular plate is threadedly connected with the screw rod. A reduction box is installed on the annular frame. The input end of the reduction box is connected to the annular frame, and the output end of the reduction box is connected to the bottom end of the screw rod. When the annular frame rotates, the screw rod is driven to rotate through the reduction box.

[0009] In addition, it is particularly preferred that the discharging device for the alginate storage tank further includes a metering mechanism, which includes a cylinder, a rotating shaft and a partition plate. The tubular part of the fixed tank is communicated with the cylinder. A rotating shaft driven by a reduction motor is installed at the center of the cylinder. Four partition plates in contact with the inner wall of the cylinder are evenly spaced and connected to the rotating shaft. The four partition plates divide the cylinder into four chambers.

[0010] In addition, it is particularly preferred that the cylinder has an upper pipe part and a lower pipe part, and the upper pipe part and the lower pipe part are respectively communicated with two different chambers.

[0011] In addition, it is particularly preferred that the discharging device for the alginate storage tank further includes a discharging mechanism, which includes a fixed ring, a rotating ring, a discharging pipe and a plug rod. The bottom end of the lower pipe part of the cylinder is connected with a fixed ring. A rotating ring is rotatably connected to the fixed ring. A discharging pipe communicated with the lower pipe part is connected to the rotating ring. The discharging pipe is inclined. A vertically sliding plug rod is arranged on the rotating ring. A return spring is connected between the plug rod and the rotating ring. A circle of jacks are spaced apart on the fixed ring. The plug rod is inserted into one of the jacks.

[0012] In addition, it is particularly preferred that the discharging device for the alginate storage tank further includes a feeding frame, a cover plate, a fixed rod, a slider, a connecting ball, a hinge block and a contact rod. The storage tank is communicated with a feeding frame at the feeding port. The bottom of the inner part of the feeding frame is inclined. The upper part of the feeding frame is rotatably connected with a cover plate. A fixed rod is connected to the cover plate. A slider is slidably connected to the fixed rod. A connecting ball is connected to the slider. A vertically sliding contact rod is arranged on the top of the storage tank. A tension spring is connected between the contact rod and the storage tank. One end of the contact rod located inside the storage tank contacts the top of the circular plate. One end of the contact rod located outside the storage tank is connected with a hinge block, and the hinge block is hinged to the connecting ball.

[0013] Compared with the prior art, the present invention has the following advantages: 1. The alginate material is stored in the storage tank and the fixed tank. When discharging is required, the servo motor is controlled to rotate the rotating cylinder, the bending rod and the annular frame. The bending rod stirs the material in the vertical direction, and the annular frame stirs the material in the horizontal direction through the cross bar part. Under the cooperation of the reduction box and the screw rod, the descending circular plate pushes the material to avoid material residue. Through the synergistic effect of the bending rod, the cross bar part and the circular plate, the agglomerated and adhered materials are effectively dispersed, and the alginate discharging effect is good.

[0014] 2. Control the reduction motor to drive the rotating shaft to rotate, drive the partition plate to rotate. The material in the fixed tank enters the upper right chamber through the upper pipe part. As the partition plate rotates, the material in the chamber is discharged through the lower pipe part, so as to automatically carry out metered discharging.

[0015] 3. The material is smoothly discharged through the inclined discharge pipe. When the discharge direction needs to be changed, pull the insertion rod. The insertion rod leaves the insertion hole, and then push the discharge pipe. When the insertion rod aligns with another insertion hole, release the insertion rod, and the return spring restores. The insertion rod inserts into another insertion hole, and the discharge direction can be adjusted according to requirements, which is convenient to adjust.

[0016] 4. Add the material into the feeding frame. The material enters the storage tank and the fixed tank for storage. After the feeding is completed, control the servo motor to make the rotating cylinder, the bent rod, the annular frame and the screw rod rotate. The circular plate moves downward. Under the action of the tension spring, the hinge block drives the cover plate to close through the connecting ball, the slider and the fixed rod. The circular plate continues to move downward for discharging. The circular plate moves upward to reset, and the cover plate opens. It can automatically open and close the cover plate, with high coordination. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0026] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with the detailed implementation mode and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0027] Embodiment 1: A discharge device for a sodium alginate storage tank. Please refer to Figures 1 - 5 , which includes a support 1, a storage tank 2, a fixed tank 3, a rotating cylinder 4, a driving mechanism, a bent rod 5, an annular frame 6, a guide rod 7 and a circular plate 8. The upper and lower parts of the support 1 are respectively fixedly connected with a storage tank 2 and a fixed tank 3. The upper part of the storage tank 2 is provided with a feed inlet 21. The fixed tank 3 is in a funnel shape, and the bottom of the fixed tank 3 has a tubular part 31. A rotating cylinder 4 driven by a driving mechanism is rotationally connected between the lower end of the storage tank 2 and the upper end of the fixed tank 3. The driving mechanism includes a toothed ring 41 and a gear 42. The outer wall of the rotating cylinder 4 is fixedly connected with a toothed ring 41. The upper part of the support 1 is rotatably connected with a gear 42 driven by a servo motor, and the gear 42 meshes with the toothed ring 41; A circle of bent rods 5 that fit with the inner wall of the fixed tank 3 are fixedly connected at intervals on the inner wall of the rotating cylinder 4. An annular frame 6 is fixedly connected between the upper ends of all the bent rods 5. The annular frame 6 has a circle of crossbar parts 61 arranged at radial intervals. A pair of guide rods 7 are fixedly connected to the inner top of the storage tank 2, and a circular plate 8 that slides up and down is arranged between the two guide rods 7.

[0028] Please refer to Figure 3 and Figure 5 , the discharge device for a sodium alginate storage tank further includes a reduction gearbox 81 and a screw rod 82. The screw rod 82 is rotatably connected to the inner top of the storage tank 2. The circular plate 8 is threadedly connected with the screw rod 82. A reduction gearbox 81 is installed on the top of the annular frame 6. The function of the reduction gearbox 81 is to reduce the speed. Its structure and principle are prior arts. The input end of the reduction gearbox 81 is connected to the annular frame 6, and the output end of the reduction gearbox 81 is connected to the bottom end of the screw rod 82. When the annular frame 6 rotates, the screw rod 82 is driven to rotate through the reduction gearbox 81.

[0029] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 7 , the discharging device for the alginate storage tank further includes a metering mechanism, which includes a cylinder 91, a rotating shaft 92 and a partition plate 93. The tubular part 31 of the fixed tank 3 is communicated with the cylinder 91. A rotating shaft 92 driven by a reduction motor is installed at the center of the cylinder 91. Four partition plates 93 are fixedly connected to the rotating shaft 92 at equal intervals. The partition plates 93 are in contact with the inner wall of the cylinder 91. The four partition plates 93 divide the cylinder 91 into four chambers. The cylinder 91 has an upper pipe part 94 and a lower pipe part 95, and the upper pipe part 94 and the lower pipe part 95 are respectively communicated with two different chambers.

[0030] First, add the alginate material into the storage tank 2 and the fixed tank 3 through the feed port 21 for storage. When discharging the material is required, control the servo motor to drive the gear 42 to rotate. Under the meshing action, drive the toothed ring 41 to rotate, and then make the rotating cylinder 4, the bending rod 5 and the annular frame 6 rotate together. When the agglomerated material passes through the interval between two adjacent cross bar parts 61, the rotating annular frame 6 uses the cross bar part 61 to dial the agglomerated material in the horizontal direction, and the rotating bending rod 5 further dials the material in the vertical direction, so as to dial the material in multiple directions and effectively loosen the agglomerated material.

[0031] At the same time, control the reduction motor to drive the rotating shaft 92 to rotate clockwise, drive the partition plate 93 to rotate together. The material in the fixed tank 3 enters the upper right chamber through the upper pipe part 94. As the partition plate 93 rotates, the material in the chamber is discharged through the lower pipe part 95, so as to automatically carry out metered discharging.

[0032] While the annular frame 6 rotates, due to the function of the reduction box 81, the screw rod 82 rotates synchronously at a reduced speed. The screw rod 82 moves the round plate 8 downward along the guide rod 7 through the thread. The round plate 8 pushes the material inside the fixed tank 3 to prevent the material from remaining in the fixed tank 3. In this way, through the coordinated action of the bending rod 5, the cross bar part 61 and the round plate 8, the agglomerated and adhered materials can be effectively dispersed, and the discharging effect of alginate is good.

[0033] Embodiment 2: On the basis of Embodiment 1, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 7, the discharging device for the alginate storage tank further includes a discharging mechanism, which includes a fixing ring 100, a rotating ring 101, a discharging pipe 102 and a plug rod 103. A fixing ring 100 is welded to the outer wall of the bottom end of the lower pipe portion 95 of the cylinder 91. A rotating ring 101 is rotatably connected to the fixing ring 100. A discharging pipe 102 communicating with the lower pipe portion 95 is connected to the rotating ring 101. The discharging pipe 102 is inclined. A plug rod 103 that slides up and down is provided on the rotating ring 101. A return spring is fixedly connected between the plug rod 103 and the rotating ring 101. A circle of jacks 104 is spaced apart on the fixing ring 100, and the plug rod 103 is inserted into one of the jacks 104.

[0034] The material in the lower pipe portion 95 is smoothly discharged to the designated position through the inclined discharging pipe 102. When it is necessary to change the discharging direction, the plug rod 103 is manually pulled down to slide, the return spring is stretched, the plug rod 103 leaves the jack 104, and then the discharging pipe 102 is pushed to rotate the whole of the discharging pipe 102, the rotating ring 101 and the plug rod 103, so as to change the discharging direction of the discharging pipe 102. When the plug rod 103 is aligned with another jack 104, the plug rod 103 is released, the return spring is restored, and the plug rod 103 is inserted into another jack 104 to fix the direction of the discharging pipe 102. In this way, the discharging direction can be adjusted according to the needs, and the adjustment is convenient.

[0035] Embodiment 3: On the basis of Embodiment 2, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 8 , the discharging device for the alginate storage tank further includes a feeding frame 111, a cover plate 112, a fixing rod 113, a slider 114, a connecting ball 115, a hinge block 116 and a contact rod 117. A feeding frame 111 is communicated with the storage tank 2 at the feeding port 21. The inner bottom of the feeding frame 111 is inclined, which is beneficial to make the material in the feeding frame 111 fall into the storage tank 2. A cover plate 112 is rotatably connected to the upper part of the feeding frame 111. A fixing rod 113 is fixedly connected to the top of the cover plate 112. A slider 114 is slidably connected to the fixing rod 113. A connecting ball 115 is fixedly connected to the slider 114. A contact rod 117 that slides up and down is provided on the top of the storage tank 2. A tension spring is fixedly connected between the contact rod 117 and the storage tank 2. One end of the contact rod 117 located inside the storage tank 2 contacts the top of the circular plate 8. One end of the contact rod 117 located outside the storage tank 2 is connected to a hinge block 116, and the hinge block 116 is hinged to the connecting ball 115.

[0036] Initially, the tension spring is in a stretched state. The top of the circular plate 8 abuts against the end of the contact rod 117, and the cover plate 112 is in an open state. The material to be stored is added into the feeding frame 111, and the material can then enter the storage tank 2 and the fixed tank 3 for storage. After the feeding is completed, the servo motor is controlled to rotate the rotating cylinder 4, the bent rod 5, and the annular frame 6. Under the action of the speed reducer 81, the screw rod 82 is driven to rotate, so that the circular plate 8 moves downward. Under the action of the tension spring, the contact rod 117 and the hinge block 116 move downward together. The hinge block 116 drives the cover plate 112 to rotate downward and close through the connecting ball 115, the slider 114, and the fixed rod 113. The slider 114 slides on the fixed rod 113, and the hinge block 116 rotates relative to the connecting ball 115. When discharging is required, the servo motor is controlled to continue rotating the rotating cylinder 4, the bent rod 5, the annular frame 6, and the screw rod 82, so that the circular plate 8 continues to move downward to assist in discharging. After the discharging is completed, the servo motor is controlled to rotate the rotating cylinder 4, the bent rod 5, the annular frame 6, and the screw rod 82 in the reverse direction. The circular plate 8 moves upward to reset. The upward-moving circular plate 8 will push the contact rod 117 to slide upward, the tension spring is stretched, and the hinge block 116 drives the cover plate 112 to rotate upward and open through the connecting ball 115, the slider 114, and the fixed rod 113, so that the material can be added into the storage tank 2 and the fixed tank 3 for storage again. In this way, the cover plate 112 can be automatically opened and closed, and the coordination is high.
