Technical Field

[0001] The utility model relates to the technical field of mud shovels, and particularly relates to a shovel for cleaning mud cakes. Background Art

[0002] Traditional thermal power plants generally burn coal for heating. The higher the sulfur content in the coal quality, the greater the design load of the desulfurization system, and the greater the sludge volume of the desulfurization wastewater system. The suspended solids in the desulfurization wastewater are very high. After this part of the suspended solids is removed by a plate-and-frame filter, mud cakes are formed on the plate-and-frame. The main components of the mud cake are the ash of the flue gas itself and the limestone added to the desulfurization system, that is, CaSO formed by Ca ions and sulfate ions. 4 After being separated by a wastewater hydrocyclone, it enters the desulfurization wastewater treatment system.

[0003] Many mud cakes are filtered out by the desulfurization system of the thermal power plant every day. Since the mud cakes are located between the filter cloths of the plate-and-frame filter, when using a traditional iron shovel to clean the mud cakes, the iron shovel is very likely to scratch the filter cloth, resulting in a high frequency of filter cloth replacement and poor filtering effect. Content of the Utility Model

[0029] The present utility model provides a shovel 100 for cleaning mud cakes.

[0030] Please refer to Figure 1 , in an embodiment of the present utility model, the shovel 100 for cleaning mud cakes includes: a shovel body 1 and a connecting rod 2. A shovel tip 11 is provided at the edge of the shovel body 1. The connecting rod 2 is connected to the shovel body 1. The shovel body 1 has two side edges distributed along the extension direction perpendicular to the connecting rod 2, and the shovel tip 11 is provided on at least one of the side edges. Both the shovel body 1 and the shovel tip 11 are made of plastic.

[0031] In the embodiments of the present utility model, the shovel body 1 is generally made of polypropylene (PP) material or polyamide (PA) material. The PP material is lightweight and easy to carry, resistant to chemical corrosion, and suitable for various chemical treatment environments; the heat resistance of PP enables it to remain stable at high temperatures, while the impact resistance ensures durability in low-temperature environments; in addition, the durability of the PP shovel reduces the replacement frequency and long-term costs. The PP shovel is environmentally friendly, has low maintenance costs, is easy to clean, and does not require special coatings or treatments. The PA shovel has good abrasion resistance and chemical stability, can withstand harsh working environments and corrosive substances, has excellent mechanical strength and durability, and can maintain its shape and function even under repeated use and heavy loads. The self-lubricating property of PA reduces the friction during shovel operation, thereby reducing maintenance requirements and operating costs. The impact resistance of the PA shovel makes it not easily broken when dropped or impacted, has good thermal stability, and can be safely used within a certain temperature range. The lightness of the PA shovel improves the convenience of operation. The shovel surface of the shovel body 1 is generally a rounded rectangle or arc-shaped structure. The rounded corner structure can reduce the damage to the filter cloth during shovel use and reduce the risk of cutting or scratching. The rounded corner design helps to reduce stress concentration, which can extend the service life of the shovel and prevent the shovel from suffering from material fatigue and fracture due to stress concentration. The thickness of the shovel body 1 is generally 5-10 mm, and the shovel body 1 has no bending structure. The thickness design of the shovel body 1 to be 5-10 mm can ensure that when the operator uses the mud cake cleaning shovel 100 to clean the mud cake, the strength of the mud shovel is not affected during the process of shoveling mud. The thickness range of 5-10 mm is suitable for most manufacturing processes, such as injection molding, etc., and can ensure the manufacturing quality and consistency of the shovel. Since the shovel surface of the shovel body 1 has no bending, when the operator uses the mud cake cleaning shovel 100 to clean the mud cake, the shovel body 1 is more easily inserted between the filter plates for mud cake cleaning work, the operation is more convenient and fast, and the mud shoveling efficiency of the operator can be greatly improved.

[0032] In one embodiment, the connecting rod 2 is generally made of the same material as the shovel body 1, such as polypropylene (PP) material or polyamide (PA) material, etc. The PP material is lightweight and easy to carry, resistant to chemical corrosion, and suitable for various chemical treatment environments; the heat resistance of PP enables it to remain stable at high temperatures, while the impact resistance ensures durability in low-temperature environments; in addition, the durability of the PP material reduces the replacement frequency of the connecting rod 2, lowering the long-term cost. The PP material is environmentally friendly, has low maintenance costs, is easy to clean, and does not require special coatings or treatments. The PA material has good wear resistance and chemical stability, can withstand harsh working environments and corrosive substances, has excellent mechanical strength and durability, and can maintain its shape and function even under repeated use and heavy loads. The self-lubricating property of the PA material reduces the friction during the operation of the shovel, thereby reducing the maintenance requirements and operating costs. The impact resistance of the PA material makes it not easily broken when dropped or impacted, has good thermal stability, and can be safely used within a certain temperature range. The lightness of the PA material improves the convenience of operation. The connecting rod 2 is generally in a cylindrical shape or a cuboid structure with rounded corners. The cylindrical or rounded corner design can prevent the operator from scratching the palm during use, and at the same time reduces the risk of the connecting rod 2 scratching the filter screen when the mud shovel is inserted into the filter plate for cleaning; the cylindrical connecting rod 2 provides a more natural grip, reducing hand fatigue during long-term use, and the transition of the rounded corners makes the grip more comfortable and reduces the risk of hand injury. This design is also convenient for cleaning because the smooth surface is not prone to accumulating dirt or residues. The connection method between the connecting rod 2 and the shovel body 1 can be a detachable connection or an integral molding through an injection mold; the connecting rod 2 and the shovel body 1 can be detachably connected by bolts or snap structures. The split structure of the connecting rod 2 and the shovel body 1 simplifies the maintenance and repair process. The operator can easily replace worn or damaged parts without having to replace the entire tool, reducing the cost of long-term use.

[0033] In an embodiment of the present utility model, the shovel tip 11 is generally made of the same material as the shovel body 1, such as polypropylene (PP) material or polyamide (PA) material, etc. The PP material is light and easy to carry, resistant to chemical corrosion, and suitable for various chemical treatment environments; the heat resistance of PP enables it to remain stable at high temperatures, while the impact resistance ensures durability in low-temperature environments; in addition, the durability of the PP material reduces the replacement frequency of the connecting rod 2, reducing long-term costs. The PP material is environmentally friendly, has low maintenance costs, is easy to clean, and does not require special coatings or treatments. The PA material has good wear resistance and chemical stability, can withstand harsh working environments and corrosive substances, has excellent mechanical strength and durability, and can maintain its shape and function even under repeated use and heavy loads. The self-lubricating property of the PA material reduces the friction during shovel operation, thereby reducing maintenance requirements and operating costs. The impact resistance of the PA material makes it not easily broken when dropped or impacted, has good thermal stability, and can be safely used within a certain temperature range. The lightness of the PA material improves the convenience of operation. Both sides of the shovel tip 11 are flat. The shovel tip 11 is located on one side of the shovel body 1 adjacent to the connecting rod 2. The design of the shovel tip 11 on the side of the shovel body 1 is beneficial for the operator to use the shovel to clean the filter mud between the plate frames. The design of the shovel tip 11 makes it easier for the shovel to penetrate the mud cake, facilitating excavation and removal. The shovel tip 11 can be used for fine operations and is convenient for operating the truss in a narrow filter plate space. The connecting rod 2 is located on the side adjacent to the shovel tip 11, which helps to effectively pry and remove the mud cake when cleaning the mud cake.

[0034] In this embodiment, a shovel 100 for cleaning the mud cake is provided. The shovel includes a shovel body 1 and a connecting rod 2 connected thereto. The shovel body 1 and the connecting rod 2 can be detachably connected by bolts or buckles, or can be integrally formed by injection molding; the shovel body 1 is designed with a working surface that extends from the shovel body 1 to form a sharp shovel tip 11, so that when the operator cleans the mud cake, the shovel tip 11 can be inserted between the filter plates for mud cake cleaning work. The shovel tip 11 is beneficial for penetrating and cleaning the mud cake adhering in the gaps. The connecting rod 2 is located on the side adjacent to the shovel tip 11, providing a good lever arm and control during operation. Both the shovel body 1 and the shovel tip 11 are made of plastic material, preferably polypropylene (PP) material or polyamide (PA) material, which are known for their light weight, durability, chemical stability, and cost-effectiveness. The plastic shovel tip 11 and the body can not only better clean the mud cake between the filter meshes, but also protect the filter cloth from being damaged by the shovel, enabling the filter cloth to be used effectively for a long time; at the same time, the plastic material reduces the weight of the tool, improves the convenience of operation, and also ensures sufficient strength and durability to meet the requirements of industrial applications. In addition, the plastic shovel is easy to process, can be mass-produced by injection molding, extrusion or other plastic forming technologies, and is also convenient for recycling, meeting environmental protection requirements.

[0035] In an embodiment of the present utility model, please refer to Figure 1 , the shovel tip 11 includes a straight section close to the shovel body 1 and a pointed section far from the shovel body 1, and a sharp angle is formed at one end of the pointed section far from the shovel body 1.

[0036] In this embodiment, a sharp angle is specifically provided at one end of the shovel tip 11 far from the shovel body 1. The sharp angle design can make the shovel have higher penetrability and is particularly suitable for cleaning the mud cake in a narrow space such as between filter plates. The sharp angle is generally not particularly sharp to prevent the shovel from damaging the filter cloth. The shovel tip 11 has a certain strength and can perform excavation and prying operations in the tightly packed mud cake.

[0037] In an embodiment of the present utility model, please refer to Figure 1 , the angle of the sharp angle is a, and the angle a of the sharp angle of the shovel tip is 60°.

[0038] In this embodiment, the angle a of the sharp angle of the shovel tip 11 is 60°. Such an angle design can make the shovel tip 11 have stronger penetrability without damaging the filter cloth. The 60° sharp angle provides a balance point, which can ensure that the shovel tip 11 has sufficient penetrability when contacting the material, and can also maintain the stability and durability of its structure, preventing damage to the filter cloth.

[0039] In practical applications, based on the positional relationship between the shovel body 1 and the shovel tip 11 in the previous embodiment, to improve the efficiency of the shovel 100 for cleaning the mud cake, the above-mentioned shovel body 1 and shovel tip 11 may also have other structural forms, which are distinguished and described below by the first embodiment to the fourth embodiment.

[0040] First embodiment

[0041] Please refer to Figure 3 , the extending direction of the shovel tip 11 is perpendicular to the side where the shovel tip 11 is located.

[0042] In this embodiment, the shovel body 1 defines a working surface for excavating or loading materials. The working surface extends to form a sharp shovel tip 11 at its front end. This shovel tip 11 is designed to improve penetrability and extend into the filter plate gap. The extending direction of the shovel tip 11 is designed to be perpendicular to the extension line of the axis of the connecting rod 2. This vertical configuration ensures that when excavating or pushing materials, the shovel can provide the maximum lever arm and stability, and at the same time can clean the mud cake between the filter plates to the greatest extent. During the manufacturing process, this vertical relationship can be achieved through precise mold design and injection molding technology to ensure that the relative positions of the shovel tip 11 and the connecting rod 2 meet the design requirements; this design improves the practicality of the shovel and the efficiency of shoveling mud.

[0043] Second embodiment

[0044] Please refer toFigure 1 , the shovel body 1 includes two shovel tips 11, and the two shovel tips 11 are located on the same side and arranged at intervals.

[0045] In one embodiment, the shovel body 1 is designed with two shovel tips 11. The two shovel tips 11 are arranged side by side on the same side of the shovel body 1, and there is a certain interval between them, thus forming a double-tipped shovel structure. This design enables the shovel to penetrate the mud cake more effectively when cleaning the mud cake. The spaced arrangement of the two shovel tips 11 provides a greater cleaning length for the mud shovel and increases the area cleaned each time. Specifically, the interval between the shovel tips 11 can be adjusted according to specific application requirements to adapt to filter plates of different sizes. This design of the double shovel tips 11 not only improves the working efficiency of the shovel but also provides a better user experience because it reduces the labor intensity during the cleaning process and can clean the mud cake at multiple points simultaneously.

[0046] Third Embodiment

[0047] Please refer to Figure 4 , the shovel body 1 includes two shovel tips 11. The shovel body 1 includes two shovel tips 11, and the two shovel tips 11 are respectively located on one of its sides.

[0048] In this embodiment, the shovel body 1 is respectively configured with a shovel tip 11 at both ends far from the extension line of the axis of the connecting rod 2. The shovel tips 11 are arranged at both ends of the shovel body 1, and the two shovel tips 11 are symmetrically or asymmetrically distributed on both sides of the axis of the connecting rod 2 along the length direction of the shovel body 1. This enables the shovel to provide greater flexibility and adaptability during use, especially when shoveling mud simultaneously. At the same time, when the operator uses this shovel for a long time to clean the mud cake, when one of the shovel tips 11 at one end is damaged or worn, the operator can rotate the mud shovel and use the shovel tip 11 at the other end for cleaning work, which is conducive to cost savings and enables the shovel to be effectively utilized.

[0049] Fourth Embodiment

[0050] Please refer to Figure 5 , the shovel body 1 includes four shovel tips 11. Every two shovel tips 11 are respectively located on one of its sides, and the two shovel tips 11 on each side are arranged at intervals.

[0051] In this embodiment, the shovel body 1 is designed with four shovel tips 11 to improve its efficiency and functionality in specific applications. The structure of the shovel body 1 allows two shovel tips 11 to be assembled at both ends far from the extension line of the axis of the connecting rod 2 respectively. The two shovel tips 11 at each end are arranged at a certain interval, forming a double-tip configuration at both ends. A pair of shovel tips 11 are designed at both ends of the shovel body 1 respectively. The two shovel tips 11 at each end are arranged at a certain distance along the length direction of the shovel body 1, so as to provide a larger contact area and stronger penetration force when cleaning the mud cake. Each pair of shovel tips 11 have the same shape and size. When the operator uses this shovel for a long time to clean the mud cake, when the shovel tips 11 at one end are damaged or worn, the operator can rotate the mud shovel and use the shovel tips 11 at the other end for cleaning work, which is beneficial to cost saving, enables the shovel to be effectively utilized, and also enhances the durability and adaptability of the shovel.

[0052] In an embodiment of the present utility model, please refer to Figure 6 , one end of the shovel tip 11 far from the shovel body 1 is serrated.

[0053] In this embodiment, the serrated design of the shovel tip 11 not only enhances the penetration force and cutting ability of the shovel tip 11, but also will not damage the filter cloth, improving the cleaning efficiency of the operator for the mud cake. The serrated shovel tip 11 also has the characteristic of self-cleaning, because its structure can easily release the material after penetrating the material, reducing the risk of the shovel tip 11 being stuck or blocked by the material. Considering durability, the geometric shape and material selection of the serrations are both to ensure that its sharpness and structural integrity are maintained during long-term use.

[0054] In an embodiment of the present utility model, please refer to Figure 2 , the shovel body 1 includes a narrowing portion 12, and the narrowing portion 12 is formed at the edge of the shovel body 1. The narrowing portion 12 narrows outward from the center of the shovel body 1, and an arc surface is formed on the side of the narrowing portion 12 facing away from the center of the shovel body 1.

[0055] In this embodiment, the edge of the shovel body 1 and the tip of the shovel tip 11 extending from the shovel body 1 are not traditional sharp or right-angled edges, but are processed into a smooth rounded corner or arc surface. The narrowing portion 12 is realized through precise injection molding and material forming techniques, ensuring a natural transition of the edge without burrs. The narrowing portion 12 is beneficial for the operator to protect the filter cloth from being scratched or damaged by the shovel when using the shovel to clean the mud cake, improving the durability and service life of the filter cloth.

[0056] In an embodiment of the present utility model, please refer to Figure 1 , the shovel body 1 and the connecting rod 2 are integrally formed.

[0057] In this embodiment, the shovel body 1 and the connecting rod 2 are realized as an integral body, that is, the two are seamlessly connected through an integral molding manufacturing process. This design avoids the weaknesses of the connection structure and connection points that may occur in the traditional multi-component assembly method, provides higher structural strength and durability. The integrally molded shovel is made by high-strength plastic processing technology, with higher strength and lighter weight.

[0058] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
