Description

Technical Field

[0001] The utility model relates to the technical field of sea mud soil making, in particular to a drum for a mobile mixing device at the sea mud soil making site. Background Technique

[0002] Sea mud is deposited in a static or slow flowing water environment and formed through physical, chemical and biochemical actions. It is unconsolidated soft fine particles or extremely fine particles and belongs to modern recent sediments. Sea mud generally has a high water content, strong viscosity, large load, and some sea mud also contains a large amount of impurities such as stones. It is a special soil that is difficult to directly utilize in engineering and generally needs to be treated before it can be resourcefully utilized. Therefore, it is necessary to treat sea mud to make it resourcefully utilized. Currently, the treatment method for sea mud in China is usually to continuously stir the sea mud and add some curing agents, gravel, loess and other substances according to the characteristics of the sea mud during the stirring process, and finally realize the dehydration and solidification of the sea mud into sea mud particles.

[0003] During the solidification process of sea mud, a turning and throwing device is needed to carry out mixing and turning operations on the sea mud. The existing turning and throwing device is equipped with a drum, and a plurality of rake knife groups are arranged on the drum. The sea mud is turned and thrown through the rake knife groups to realize the dispersion and solidification of the sea mud into sea mud particles. Directly applying the existing turning and throwing device to the mixing of sea mud soil making will cause problems such as too much resistance to the rake knives due to the strong viscosity of the sea mud. The distance between adjacent rake knives is too large, resulting in poor dispersion effect on the sea mud and unable to produce sea mud particles that meet the size requirements according to the needs of customers; the distance between adjacent rake knives is too small, and the sea mud contains a large amount of impurities such as stones. During mixing, the impurities such as stones cannot be discharged from the gap between two adjacent rake knives, causing damage to the rake knives and reducing the service life of the rake knives. And the angle between the rake knife group and the horizontal axis of the drum will also affect the turning and throwing of the sea mud. If the angle is too large, due to the large weight of the sea mud, the sea mud directly falls between the next group of rake knives for cutting after being cut by the previous group of rake knives. The diameter of the sea mud particles is relatively large and it is difficult to meet the customer's requirements. And there is no centralized turning and throwing of the sea mud. After the sea mud forms particles, it is turned and thrown by the turning and throwing device, with strong dispersibility and difficult to form a pile; if the angle is too small, there is a relatively large gap between the rake knives, the sea mud is not turned and thrown sufficiently, and the impurities in the sea mud directly hit the front of the rake knives, with too much force, which is easy to cause damage to the rake knives and reduce the service life of the rake knives. Content of the Utility Model

[0004] The purpose of the utility model is to provide a drum for a mobile mixing device at the sea mud soil making site. The structure of the drum is simple. During the process of turning and throwing the sea mud, it will neither cause damage to the mixing claws, increase the service life of the drum, nor can meet the crushing requirements of the particle size of the mixed sea mud.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A drum for a mobile mixing device at the site of making soil from marine mud, comprising a cylinder body. A number of groups of mixing claw arrays are provided on the outer surface of the cylinder body. The mixing claw arrays are in a V shape in the unfolded surface of the cylinder body, and the vertex of the V shape is located at the vertical axis of the unfolded surface of the cylinder body. Each mixing claw array includes a number of mixing claws arranged at intervals in sequence. The axial distance between two adjacent mixing claws is 5-10 times the diameter of marine mud particles. The angle between the straight line where the mixing claw array is located and the horizontal axis of the cylinder body is the spiral lift angle, and the range of the spiral lift angle is 15 degrees - 17 degrees.

[0007] Preferably, the mixing claws between two adjacent mixing claw arrays are staggered.

[0008] Preferably, the mixing claw includes a vertical blade connected to the cylinder body and a curved blade fixedly connected to the other end of the vertical blade. The curved blade forms an angle of 40-60 degrees with the vertical blade, and the curved blade extends towards the vertical axis of the drum along the direction of the mixing claw array where it is located.

[0009] Preferably, when the mixing claw is connected to the cylinder body, the vertical blade is parallel to the vertical axis of the drum, and the vertical blade and the curved blade are integrally formed.

[0010] In the above technical solution, the marine mud generally has a high water content, strong viscosity, and great resistance to the drum. Moreover, a large amount of impurities such as stones are also contained in the marine mud. Therefore, the shape of the mixing claw is selected as a sheet shape, which can avoid being blocked by hard objects when the drum rotates and can reduce the wear of the mixing claw. The mixing claw arrays are in a V shape in the unfolded surface of the cylinder body, and the vertex of the V shape is located at the vertical axis of the unfolded surface of the cylinder body, so that each mixing claw array coils around the cylinder body. When the drum rotates, each group of mixing claw arrays can gather the materials from both sides to the middle, which is convenient for concentrating the gathered marine mud materials together and throwing them up, avoiding the problem of excessive dispersion after being thrown up. The materials are concentrated and thrown towards the middle, and then the materials fall freely to form a pile. Further, by setting the spiral lift angle to 15-17 degrees and matching the length of the drum with the circumference of the outer surface of the drum, during the operation of the drum, each group of mixing claw arrays occupies half of the position in the unfolded surface of the drum surface. In this way, it will not be due to the V shape angle being too large that during the turning and throwing of the marine mud, due to the large weight and strong viscosity of the marine mud, when the marine mud gathers from both ends to the middle of the mixing claw array, it directly falls off the current mixing claw array, resulting in incomplete turning and throwing of the marine mud, nor will it be due to the V shape angle being too small that the force on a single mixing claw is too large, causing damage to the mixing claw.

[0011] By setting the axial distance between two adjacent mixing claws to 5-10 times the diameter of the sea mud particles, when turning over the sea mud, it can meet the crushing requirements of the mixing fineness of the sea mud particles while reducing the impact on the mixing claws and increasing the service life of the mixing claws. By setting the mixing claws to be connected by a vertical blade and a curved blade, when the vertical blade is connected to the drum, it is parallel to the vertical axis of the drum, dispersing the sea mud while reducing the blockage of the sea mud. The curved blade forms an angle of 40-60 degrees with the vertical blade, and the curved blade extends towards the vertical axis of the drum along the direction of the mixing claw array where it is located, blocking the sea mud while guiding the sea mud, so that during the flipping process of the drum, the sea mud can be more concentrated and gathered towards the middle. By integrally forming the vertical blade and the curved blade, the structure of the mixing claw is more solid and less likely to be damaged when turning over the sea mud. Description of the Drawings

[0017] The following further describes the present utility model in conjunction with the drawings:

[0018] As Figures 1 to 4As shown in the figure, a drum for a mobile mixing equipment at the sea mud soil-making site includes a cylinder body 1, which is installed on the mobile mixing equipment at the sea mud soil-making site. On the outer surface of the cylinder body 1, there are several groups of mixing claw arrays 2. There are 5 - 6 groups of mixing knife arrays. The mixing claw arrays 2 are in a V shape in the unfolded surface of the cylinder body 1. The vertex of the V shape is located at the vertical axis of the unfolded surface of the cylinder body 1, so that each mixing claw array 2 coils around the cylinder body 1. When the cylinder body 1 rotates, each group of mixing claw arrays 2 can gather the materials from both sides to the middle, facilitating the concentrated throwing up of the gathered sea mud materials together, avoiding excessive dispersion after throwing up, concentrating on throwing up to the middle, and then the materials fall freely to form a pile shape. The angle between the straight line where the mixing claw array 2 is located and the horizontal axis of the cylinder body 1 is the spiral lift angle, and the range of the spiral lift angle is 15 degrees - 17 degrees. According to the length of the cylinder body 1 and the circumference of the outer surface of the cylinder body 1, during the operation of the cylinder body 1, each group of mixing claw arrays 2 occupies half of the position in the unfolded surface of the cylinder body 1. In this way, it will not be due to too large a V shape angle that during the turning and throwing of the sea mud, due to the large weight and strong viscosity of the sea mud, the sea mud will break away from the current mixing claw array 2 and directly fall when gathering from both ends of the mixing claw array 2 to the middle, resulting in incomplete turning and throwing of the sea mud. Nor will it be due to too small a V shape angle that the force on a single mixing claw 3 is too large, causing damage to the mixing claw 3. Further, the mixing claws 3 between two adjacent mixing claw arrays 2 are arranged staggeredly. This arrangement can enable the materials leaking through the gap between two mixing claws 3 to be caught and turned over by the next group of mixing claws 3 when the cylinder body 1 rotates and works.

[0019] The mixing claw arrays 2 are evenly distributed around the cylinder body 1. Each group of mixing claw arrays 2 includes several mixing claws 3 arranged at intervals in sequence. The axial distance between two adjacent mixing claws 3 is 5 - 10 times the diameter of the sea mud particles, so that when turning and throwing the sea mud, while meeting the crushing requirements of the mixing fineness of the sea mud particles, the impact on the mixing claws 3 can be reduced, and the service life of the mixing claws 3 can be increased. The mixing claw 3 includes a vertical blade 31 connected to the cylinder body 1 and a curved blade 32 fixedly connected to the other end of the vertical blade 31. Generally, the water content of the sea mud is relatively high, the viscosity is relatively strong, the resistance to the drum is large, and there are also a large number of impurities such as stones in the sea mud. Therefore, the shape of the mixing claw 3 is selected as a blade shape, which can avoid being blocked by hard objects when the cylinder body 1 rotates and can reduce the loss of the mixing claw 3. When the vertical blade 31 is connected to the cylinder body 1, it is parallel to the vertical axis of the drum, dispersing the sea mud while reducing the blockage of the sea mud. The curved blade 32 forms an angle of 40 - 60 degrees with the vertical blade 31, and the curved blade 32 extends towards the vertical axis of the cylinder body 1 along the direction of the corresponding mixing claw array 2, blocking the sea mud while guiding the sea mud, so that during the flipping process of the cylinder body 1, the sea mud can be gathered more concentratedly towards the middle. Further, the vertical blade 31 and the curved blade 32 are integrally formed, making the structure of the mixing claw 3 more solid and less likely to be damaged when turning and throwing the sea mud.

[0020] This embodiment is only an illustration of the concept and implementation of the present utility model, and does not limit it. Under the concept of the present utility model, technical solutions without substantial transformation are still within the scope of protection.
