Abstract
Description
Technical Field
[0001] The utility model belongs to the field of sludge drying racks, in particular to a lifting type sludge drying rack. Background Art
[0002] During sewage treatment, the sewage passes through the filter press, and the sludge in the sewage is pressed into a cake shape. The cake-shaped sludge needs to be further dried. There are many purposes for drying, such as: to meet the moisture content requirements of the corresponding sludge discharge in the local area; to reduce weight and facilitate transportation; to make the sludge safe and stable, and reduce the hazards such as pathogens and heavy metals contained in it; to facilitate the recycling of waste materials, building materials, etc. At present, the cake-shaped sludge is placed on a multi-layer drying rack, which is located in the drying room to dry the sludge, but the height of the drying rack is relatively large. Whether the sludge on the upper layer of the drying rack is put in or taken out, it needs to be assisted by a footrest tool. The height travel of the sludge is relatively large, which increases the labor intensity of the workers, and the climbing operation is easy to cause the workers to fall and the safety is poor. This is a problem that needs to be solved urgently. Utility Model Content
[0003] The purpose of the utility model is to provide a lifting type sludge drying rack, which has the advantages of reducing the labor intensity of workers and having good safety.
[0004] The technical solution of the utility model is as follows: a lifting sludge drying rack comprises a bottom plate, a top plate is arranged above the bottom plate, a plurality of shelves arranged from top to bottom are arranged between the bottom plate and the top plate, a motor with double output shafts is arranged on the top of the top plate, steering wheels are arranged at the four corners of the top plate, two output ends of the motor are provided with two pulleys, ropes are connected to the rope wheels, one end of the rope passes around the steering wheel on the corresponding corner and then extends downward, passes through the top plate and connects all the shelves.
[0005] In the aforementioned lifting sludge drying rack, the bottom plate is connected to the top plate via four columns, and the four columns are respectively located at the four corners of the top plate.
[0006] In the aforementioned lifting sludge drying rack, the upright column passes through all the shelves, and a plurality of guide sleeves are provided on the upright column. The plurality of guide sleeves are respectively fixed on the plurality of shelves, and the bottom of the guide sleeve is fixed to the top surface of the shelf.
[0007] In the aforementioned lifting sludge drying rack, a spiral spring is arranged on the outer side of the guide sleeve, and a cloth sleeve is arranged on the outer side of the spring, and the cloth sleeve is fixed to the spring.
[0008] In the aforementioned lifting sludge drying rack, four pressing plates are provided on the outer side of the shelf, and the four pressing plates are respectively located on the outer sides of four ropes. The ropes pass through between the corresponding pressing plates and the shelf, and the pressing plates are connected to the shelf screws.
[0009] In the aforementioned lifting sludge drying rack, the motor is connected to the mains via a forward / reverse switch.
[0010] Compared with the prior art, the utility model uses multiple shelves distributed up and down to place the sludge. The height of the shelves can be adjusted to adapt to the optimal operating height of the human body. At the same time, the workers' travel distance for taking and placing the sludge is reduced, so that the workers' labor intensity is reduced. When taking and placing the sludge, the workers can operate on the ground without the need for high-altitude operations, and the safety is also better. Therefore, the utility model has the advantages of reducing the labor intensity of workers and better safety.
[0011] In addition, by establishing a sliding connection between the shelf and the column through the guide sleeve, the shelf will not shake horizontally or tilt, preventing sludge from falling from the shelf, further reducing the labor intensity of workers. By setting a cloth sleeve on the outside of the guide sleeve and setting a spring as a skeleton inside the cloth sleeve, sludge debris is prevented from entering between the column and the guide sleeve, ensuring smooth lifting of the shelf and effectively reducing the failure rate.

[0017] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0018] Embodiment. A lifting sludge drying rack, such as Figure 1 As shown, it includes a bottom plate 1, a top plate 2 is provided above the bottom plate 1, a plurality of shelves 3 arranged from top to bottom are provided between the bottom plate 1 and the top plate 2, the shelves 3 are used to place cake-shaped sludge, and a double-output shaft motor 4 is provided on the top of the top plate 2. The motor 4 has a reducer, and a brake is provided inside the motor 4 to achieve self-locking in the case of power failure. This is an existing product.
[0019] Steering wheels 5 are provided at the four corners of the top plate 2, and the steering wheels 5 are connected to the top plate 2 through a wheel frame. Two output ends of the motor 4 are provided with two pulleys 6, and ropes 7 are connected to the pulleys 6. One end of the rope 7 passes around the steering wheel 5 on the corresponding corner and extends downward, passes through the top plate 2 and connects all the shelves 3.
[0020] The bottom plate 1 is connected to the top plate 2 via four cylindrical columns 8 , and the four columns 8 are respectively located at the four corners of the top plate 2 .
[0021] The column 8 passes through all the shelves 3 , and a plurality of guide sleeves 9 are provided on the column 8 . The plurality of guide sleeves 9 are respectively fixed on the plurality of shelves 3 , and the bottom of the guide sleeves 9 is fixed to the top surface of the shelf 3 .
[0022] A spiral spring 10 is disposed on the outer side of the guide sleeve 9 , and a cloth sleeve 11 is disposed on the outer side of the spring 10 . The cloth sleeve 11 is fixed to the spring 10 .
[0023] Four pressing plates 12 are arranged on the outside of the shelf 3, and the four pressing plates 12 are respectively located on the outside of the four ropes 7. The ropes 7 pass through the corresponding pressing plates 12 and the shelf 3, and the pressing plates 12 are screwed to the shelf 3. After loosening the screws on the pressing plates 12, the position of the shelf 3 on the ropes 7 can be changed, thereby changing the distance between the shelves 3, so that the drying rack is suitable for placing cake-shaped sludge of different thicknesses from different filter presses, and the drying rack has a wide range of applications.
[0024] The motor 4 is connected to the mains via a forward / reverse switch.
[0025] Working principle: Figure 1 As shown, in the initial condition, the distances between the shelves 3 are equal, and the distances between the shelves 3 are greater than the thickness of the cake-like sludge, leaving sufficient evaporation space.
[0026] When it is necessary to put the sludge on the upper shelf 3 or take the dried sludge off the upper shelf 3, the forward and reverse switches are used to reverse the motor 4, which drives the rope wheel 6 to reverse, and the rope 7 on the rope wheel 6 is loosened, so that all the shelves 3 are lowered as a whole. Since the shelves 3 are connected by flexible ropes 7, when the bottom shelf 3 is lowered to the lowest position, the upper shelf 3 can continue to be lowered, and finally all the shelves 3 are at a lower position, which is convenient for workers to take and put the sludge.
[0027] When taking and placing sludge from the drying rack, the sludge on all the shelves 3 should be taken and placed from bottom to top. When the height of the shelf 3 where the sludge is taken and placed is too high, the motor 4 is driven to work by the forward and reverse switch to change the height of the corresponding shelf 3.
