Description

A crushing and mixing device that combines straw and silt Technical Field

[0001] This utility model relates to the field of sludge treatment devices, and in particular to a crushing and mixing device that combines straw and sludge. Background Technology

[0002] Large amounts of silt are required for land reclamation and tidal flat development projects in coastal areas. On the one hand, because dredging is currently carried out using hydraulic methods such as cutter suction, the dredged silt has high water content, high clay content, low strength, and poor drainage performance. Under natural air drying and consolidation conditions, silt foundations generally require several years before they can be used. On the other hand, the water in the silt generated along the coast is seawater, containing a large amount of salt. During natural air drying, as the water evaporates, a large amount of salt remains in the soil, forming saline soil with low fertility, making it unsuitable for cultivation for a long time.

[0003] Application No. 201510143588.0, entitled "A Method for Rapid Ecological Treatment of Coastal Tidal Flat Silt", discloses a method of improving the permeability of the mixture on the upper layer of straw blanket by mixing silt with straw fragments. This allows the upper freshwater layer to penetrate into the mixture more quickly during the salt washing and vacuum consolidation process, thereby accelerating the entire ecological treatment process and the silt consolidation process.

[0004] The following problems currently exist;

[0005] In practice, uneven ecological treatment results have been observed due to the size of the straw fragments and uneven mixing with silt. Therefore, how to ensure that the straw fragments are crushed to the required degree while being evenly mixed with silt is a problem to be solved. Summary of the Invention

[0006] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model.

[0010] As a preferred embodiment of the crushing and mixing device for combining straw and silt described in this utility model, the mixing drum has a toothed ring at the top of its inner wall, which meshes with several sets of planetary gears. The bottom of the planetary gears is connected to a drive shaft B. A limiting plate is provided at the bottom of the toothed ring, and the limiting plate and the chuck are engaged between the planetary gears and the mixing roller.

[0025] Example 1

[0026] Referring to Figures 1 to 6, this embodiment provides a crushing and mixing device for combining straw and sludge, including a mixing drum 100, which is a hollow cylinder with legs fixedly connected to its bottom; and a mixing mechanism 200, which includes a transmission assembly 201 and several sets of mixing assemblies 202, located inside the mixing drum 100. The transmission assembly 201 includes a servo motor 201a located outside the mixing drum 100. At the top of the wall, at the axis, the output end of the servo motor 201a is connected to the drive shaft A201b, the drive shaft A201b is fixedly connected to the sun gear 201c, the bottom of the sun gear 201c is provided with a chuck 201d, the bottom of the chuck 201d is provided with a grinding roller 201e, and several sets of stirring components 202 include planetary gears 202a and stirring rollers 202c. The sun gear 201c meshes with several sets of planetary gears 202a, and the several sets of stirring components 202 all rotate around the axis with the drive component 201 as the axis.

[0027] A gear ring 101 is provided on the top of the inner wall of the mixing drum 100. The gear ring 101 meshes with several sets of planetary gears 202a. The bottom of the planetary gears 202a is connected to a drive shaft B202b. A limit plate 102 is provided at the bottom of the gear ring 101. The limit plate 102 and the chuck 201d are both engaged between the planetary gears 202a and the mixing roller 202c. Through this engagement relationship, the height of the mixing mechanism 200 inside the mixing drum 100 is fixed and supported.

[0028] The stirring roller 202c is a hollow cylinder. Several sets of crushing teeth B202c-1 are provided on the outer wall of the stirring roller 202c. Filter holes 202c-2 are opened through the outer wall of the stirring roller 202c. Crushing teeth 201e-1 are also provided on the outer wall of the grinding roller 201e. The crushing teeth 201e-1 and filter holes 202c-2 rotate alternately. A feed inlet 103 is provided at the top of the mixing drum 100. When the equipment needs to start working, sludge and straw fragments are placed into the mixing drum 100 through the feed inlet 103. The servo motor 201a drives the sun gear 201c to rotate through the drive shaft A201b. Since the sun gear 201c meshes with several sets of planetary gears 202a, and the planetary gears 202a mesh with the gear ring of the mixing drum 100... The components 101 mesh with each other, causing the drive shaft A201b to drive the sun gear 201c, chuck 201d, and grinding roller 201e to rotate around the mixing drum 100. Meanwhile, several sets of mixing rollers 202c rotate around the grinding roller 201e in opposite directions. The interlaced crushing teeth 201e-1 and 201c-1 further crush the straw that has not been completely crushed. When the straw is crushed to the required degree, its volume decreases and it can freely enter and exit the mixing roller 202c through the filter hole 202c-2 after mixing with the sludge. However, the straw that is not crushed to the required degree will remain on the outer wall of the mixing roller 202c and continue to be crushed through the interlacing of the crushing teeth B202c-1 and the crushing teeth 201e-1.

[0029] The bottom of the mixing drum 100 has the same number of discharge ports 104 as the mixing components 202, and the diameter of several discharge ports 104 is smaller than the diameter of the mixing rollers 202c. A solenoid valve is provided at the end of the discharge port 104. After the device has completed the mixing of straw and sludge, the servo motor 201a is controlled to make several mixing rollers 202c stop at the corresponding position of the discharge port 104. Then the valve is opened. At this time, the straw and sludge mixture that meets the crushing standard will be discharged through the filter hole 202c-2 and the discharge port 104 in sequence, while the straw that does not meet the crushing standard will remain inside the mixing drum 100 and be further crushed in the next operation of the equipment.

[0030] Furthermore, the servo motor 201a and the solenoid valve are both common existing technologies in real life, so their installation, principle, power supply, etc. will not be described in detail here.

[0031] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application). For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of elements may be inverted or otherwise altered, and the nature or number or position of discrete elements may be changed or altered. Therefore, all such modifications are intended to be included within the scope of this utility model.

Without departing from the scope of this invention, other substitutions, modifications, alterations, and omissions may be made in the design, operation, and arrangement of the exemplary embodiments. Therefore, this invention is not limited to the specific embodiments, but extends to various modifications that still fall within the scope of the appended claims.
