Description

Technical Field

[0001] The present application relates to the technical field of sludge drying equipment, and in particular to a split-type sludge drying equipment. Background Art

[0002] Sludge drying equipment is a device used to dry sludge. Existing sludge drying equipment generally uses mesh belts to transport sludge. The mesh belts of existing equipment are generally designed within three layers, resulting in poor drying effect of sludge in the drying room and low transportation efficiency. Therefore, in order to improve the drying and transportation efficiency, it is necessary to increase the number of mesh belt layers, which in turn causes the overall equipment to be too high, exceeding the transportation limit, and cannot be transported using conventional methods. Utility Model Content

[0003] The purpose of the embodiments of the present application is to provide a split-type sludge drying equipment, which overcomes the problem of excessive height through a split-type design and facilitates the transportation of the equipment.

[0004] To achieve the above objectives, this application adopts the following technical solutions:

[0005] In one aspect, a split-type sludge drying device is provided, comprising: a baking chamber mechanism, a dust removal mechanism, N layers of mesh belts, and a power mechanism. A baking chamber is formed in the baking chamber mechanism, the mesh belts are vertically spaced apart in the baking chamber, the power mechanism is mounted on one side of the baking chamber mechanism, and its power end is connected to the mesh belts. The dust removal mechanism is detachably mounted on the top of the baking chamber mechanism, wherein N>3;

The dust removal mechanism includes a plurality of second boxes corresponding to the positions of the first boxes, and a second opening is provided on the bottom of the second boxes. A positioning portion is provided on the edge of the second opening or the first opening, and the second box is locked to the top of the first box through the positioning portion, so that the first opening and the second opening are correspondingly connected.

[0007] Furthermore, the interval between each layer of mesh belts is between 190-400 mm.

[0008] Furthermore, the mesh belt is made of elastic material.

[0009] Furthermore, a multi-layer support frame is provided in the baking cavity, and the mesh belt is installed on the support frame.

[0010] Furthermore, an elastic support member is provided between the support bracket and the mesh belt.

[0011] Furthermore, the cross section of the elastic support member is L-shaped.

[0012] Furthermore, the dust removal mechanism also includes a pulse component, and the pulse component is installed in the second box.

[0013] Furthermore, the pulse assembly includes a fixed plate, a filter cartridge and an air jet pipeline. The fixed plate is installed in the second box body and divides the second box body into two upper and lower cavities. The filter cartridge is installed at the bottom of the fixed plate and is located in the lower cavity. The air jet pipeline is installed at the top of the second box body, and its part extends into the upper cavity and is gas-connected to the filter cartridge.

[0014] Furthermore, the jet pipeline includes an air collecting pipe, multiple air distribution pipes, multiple air jet pipes and multiple air nozzles. The multiple air distribution pipes are respectively connected to the air collecting pipe, and the multiple air jet pipes are respectively connected to the same air distribution pipe. The air outlet end of the air jet pipe is connected to the air nozzle, and the air nozzle is connected to the air inlet of the filter cartridge.

[0015] Furthermore, it also includes a heat pump mechanism and a return air duct. The heat pump mechanism is installed on one side of the baking room mechanism.

[0016] Furthermore, the return air duct is detachably connected to the dust removal mechanism, and / or the return air duct is detachably connected to the heat pump mechanism.

[0017] Furthermore, the dust removal mechanism and the return air duct are an integrally formed part, and / or the baking room mechanism and the heat pump mechanism are an integrally formed part.

[0018] The beneficial effects of the present application are as follows: considering that the multi-layer mesh belt design leads to an increase in the height of the baking room mechanism, if the dust removal mechanism is integrated, it will exceed the transportation limit. The present application adopts a split design, and the baking room mechanism is divided into multiple first boxes that are spliced ​​in sequence along the first conveying direction. Each box is provided with a first opening on the top to facilitate subsequent docking with the dust removal mechanism.

The two are precisely locked by the positioning parts set at the edge to ensure that the first opening is correspondingly connected to the second opening, forming a complete drying and dust removal system.

DETAILED DESCRIPTION

[0028] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0030] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0031] like Figures 1-6 As shown, this embodiment provides a split-type sludge drying equipment, including: a baking room mechanism 1, a dust removal mechanism 2, N layers of mesh belts 3 and a power mechanism. A baking cavity 1011 is formed in the baking room mechanism 1, and the mesh belts 3 are arranged in the baking cavity 1011 at intervals along the vertical direction. The power mechanism is installed on one side of the baking room mechanism 1, and its power end is connected to the mesh belt 3. The dust removal mechanism 2 is detachably installed on the top of the baking room mechanism 1, wherein N>3; the baking room mechanism 1 includes a plurality of first boxes sequentially spliced ​​along a first conveying direction. The first box body 101 is provided with a first opening 1012 on the top of each of the first box bodies 101, and the dust removal mechanism 2 includes a plurality of second box bodies 201 corresponding to the positions of the first box bodies 101, and the second box bodies 201 are provided with a second opening 2011 on the bottom, and a positioning portion is provided on the edge of the second opening 2011 or the first opening 1012, and the second box body 201 is locked to the top of the first box body 101 through the positioning portion, and the first opening 1012 is connected to the second opening 2011 accordingly.

[0032] Based on the above scheme, the split-type sludge drying equipment proposed in this application has a working principle that mainly revolves around the two core elements of efficient drying and convenient transportation. The specific working process is as follows: the power mechanism is started to drive N layers (N>3) of mesh belts 3 to circulate in the baking chamber 1011 spaced apart in the vertical direction. The sludge is evenly placed on the mesh belt 3. As the mesh belt 3 moves, it is dried layer by layer through the baking chamber 1011 in the baking room mechanism 1. The heat source in the baking room mechanism 1 generates heat, and the sludge on the mesh belt 3 is dried through the hot air circulation in the baking chamber 1011. Since the mesh belt 3 has many layers, the sludge can receive heat layer by layer, thereby improving the drying efficiency. During the drying process, since the mesh belt 3 is porous, as the sludge dries, dust will fall along the pores of the mesh belt 3. The dust removal mechanism 2 can effectively remove the dust on the mesh belt 3.

[0033] To address the issue of exceeding the overall equipment height limit, the baking room mechanism 1 is designed to consist of multiple first boxes 101, which are sequentially connected along the first conveying direction. The dust removal mechanism 2, in turn, is composed of multiple second boxes 201. Both are packaged and shipped separately at the factory, reducing the height and volume of each piece. Upon arrival at the destination, the second box 201 is precisely locked to the top of the first box 101 via a positioning mechanism, ensuring that the first opening 1012 and the second opening 2011 are in contact, allowing for rapid assembly and installation of the baking room mechanism 1 and the dust removal mechanism 2. The first opening 1012 and the second opening 2011 are designed to ensure connectivity between the interiors of the baking room mechanism 1 and the interiors of the dust removal mechanism 2, both for effective dust removal and for return air circulation within the baking chamber 1011.

[0034] In general, this solution increases the number of mesh belt layers (N>3) so that the sludge can receive heat layer by layer in the drying room mechanism 1, thereby improving drying efficiency and shortening drying time. The split design breaks down the taller drying room mechanism 1 and dust removal mechanism 2 into multiple smaller boxes for transportation, effectively solving the problem of the overall equipment exceeding the height limit, facilitating the use of conventional transportation methods, and reducing transportation costs. On-site splicing and installation are simple and quick, and precise docking is achieved through the positioning unit, which improves installation efficiency and reduces installation difficulty. The split design also makes equipment maintenance more convenient. When a component needs to be repaired or replaced, the corresponding box can be removed separately for processing without disassembling the entire equipment.

[0035] Optionally, the spacing between each layer of mesh belts 3 is precisely controlled to be between 190 and 400 mm to ensure that the sludge can receive heat evenly and efficiently, optimizing the drying effect and improving thermal efficiency. The power mechanism drives the mesh belts 3 in a circular motion, achieving continuous drying of the sludge. In this solution, the maximum number of mesh belts 3 is set to 5. When there are 5 layers of mesh belts 3, the spacing between each layer of mesh belts 3 is 255 mm. When there are 4 layers of mesh belts 3, the spacing between each layer of mesh belts 3 is 340 mm. The overall height of the baking room mechanism 1 is approximately 2840 mm. In this case, installing the dust removal mechanism 2 on the top of the baking room mechanism 1 will inevitably cause the overall height of the equipment to exceed the transportation limit. Therefore, the baking room mechanism 1 is divided into multiple first boxes 101 that can be spliced ​​together. Each box has a first opening 1012 at the top. The dust removal mechanism 2 is correspondingly composed of multiple second boxes 201. This design not only reduces the height and volume restrictions during transportation, but also facilitates rapid on-site splicing and installation, improving the flexibility and convenience of the equipment. At the same time, according to actual design requirements, the minimum interval of the mesh belt 3 can be set at 190 mm and the maximum interval can be set at 400 mm, and the number of layers of the mesh belt 3 and the overall height of the equipment can be adaptively adjusted.

[0036] Furthermore, the mesh belt 3 is made of elastic material. The mesh belt 3 made of elastic material can, to a certain extent, adapt to the morphological changes that may occur in the sludge during the drying process, such as volume shrinkage or surface agglomeration, etc., to ensure that the sludge can move smoothly on the mesh belt 3, reduce blockage and stagnation, and improve drying efficiency. Elastic materials usually have good wear resistance, corrosion resistance and high temperature resistance, which enables the mesh belt 3 to maintain stable performance and a long service life under long-term, high-intensity use. At the same time, elastic materials can also effectively alleviate stress concentration problems caused by uneven sludge weight distribution or mechanical vibration, reducing the risk of damage to the mesh belt 3. In addition, because the elastic material has a certain degree of flexibility and resilience, the mesh belt 3 can better maintain a stable state during operation, reducing noise and energy loss caused by vibration and offset. This not only improves the operating efficiency of the equipment, but also reduces maintenance costs.

[0037] Furthermore, a multi-layer support frame 102 is specially designed inside the baking chamber 1011 to support and fix the mesh belt 3, ensuring its stability and durability during the drying process. These support frames 102 are made of alloy steel, which, with its high strength, corrosion resistance, and high temperature resistance, provides a solid support foundation for the mesh belt 3. In order to prevent the support frames 102 from wearing out during the long-term support of the mesh belt 3, thereby affecting the overall performance and life of the equipment, the present application cleverly arranges elastic support members 103 between the support frames 102 and the mesh belt 3. These elastic support members 103 can not only effectively disperse the pressure of the mesh belt 3 on the support frames 102, reducing the wear caused by direct contact, but also absorb and alleviate the impact and stress caused by mechanical vibration or changes in sludge weight to a certain extent, protecting the mesh belt 3 and the support frames 102 from damage. The design of the elastic support members 103 not only improves the durability and stability of the equipment, but also ensures the smooth operation of the mesh belt 3 during the drying process. They allow the mesh belt 3 to have a certain buffer and adjustment space when subjected to external forces, thereby avoiding poor operation or damage caused by excessive tension or relaxation.

[0038] In addition, the cross-section of the elastic support member 103 is L-shaped. The L-shaped cross-section allows the elastic support member 103 to fit more closely between the support bracket 102 and the mesh belt 3, forming a stable support structure. The support bracket 102 serves as a fixed support point and is closely connected to the elastic support member 103 through the long side of the L-shape, ensuring the stable transmission of the supporting force, while the mesh belt 3 is in contact with the short side of the L-shape. This design effectively disperses the direct pressure of the mesh belt 3 on the support bracket 102 and reduces wear. At the same time, the L-shaped structure also provides a certain deformation space for the elastic support member 103. When the mesh belt 3 is running or subjected to external force, the elastic support member 103 can use its good elasticity to deform and buffer to a certain extent, absorb and alleviate impact and stress, thereby protecting the mesh belt 3 and the support bracket 102 from damage. In addition, the L-shaped cross-section is also convenient for installation and maintenance. Technicians can easily insert it between the support bracket 102 and the mesh belt 3, and complete the installation without complicated tools and steps. When maintenance and replacement are required, the elastic support member 103 can also be quickly disassembled and replaced, reducing maintenance costs and downtime.

[0039] In some embodiments, the dust removal mechanism 2 also includes a pulse component 202, which is installed in the second box body 201. The introduction of the pulse component 202 is an important measure to more efficiently remove the dust and particulate matter generated during the drying process. The filter element in the dust removal mechanism 2 is periodically cleaned by means of high-pressure gas pulse spraying. When a certain amount of dust accumulates on the filter element, a strong shock wave is formed by releasing a high-pressure gas pulse to shake off and collect the dust on the filter element, thereby restoring the filtering performance of the filter element and ensuring the continuous and efficient dust removal effect. In the context of a split design, the pulse component 202 is cleverly integrated into the second box body 201, which not only maintains the compactness of the equipment structure, but also facilitates maintenance and management. At the same time, the automatic control and timed cleaning functions of the pulse component 202 also greatly reduce the need for manual intervention and improve the intelligence level and operating efficiency of the equipment.

[0040] Specifically, the pulse assembly 202 includes a fixing plate 2026, a filter cartridge 2025, and an air jet pipe 2023. The fixing plate 2026 is installed in the second housing 201 and divides the second housing 201 into two upper and lower chambers. The filter cartridge 2025 is installed at the bottom of the fixing plate 2026 and is located in the lower chamber. The air jet pipe 2023 is installed at the top of the second housing 201 and partially extends into the upper chamber to be gaseously connected to the filter cartridge 2025. First, the fixing plate 2026 serves as the support structure of the pulse assembly 202 and is firmly installed inside the second housing 201. It not only provides a stable mounting platform for components such as the filter cartridge 2025 and the air jet pipe 2023, but also cleverly divides the second housing 201 into two upper and lower chambers through its unique layout. This design not only optimizes space utilization but also facilitates subsequent maintenance and cleaning. The filter cartridge 2025, the core component of dust removal, is mounted at the bottom of the fixed plate 2026 and located within the cavity below. Filled with high-efficiency filter material, the filter cartridge 2025 effectively intercepts and collects dust and particulate matter generated during the drying process. As the drying process progresses, a layer of dust gradually accumulates on the surface of the filter cartridge 2025, affecting dust removal effectiveness. This is where the pulse assembly 202 comes into play. The air jet 2023 is mounted on the top of the second housing 201 and cleverly extends into the cavity above, establishing a pneumatic connection with the filter cartridge 2025. When the pulse assembly 202 is activated, high-pressure gas rapidly enters the filter cartridge 2025 through the air jet 2023, creating a powerful pulsed airflow. This airflow instantly impacts the dust layer on the surface of the filter cartridge 2025, shaking it off and collecting it in the cavity below. Simultaneously, the pulsed airflow thoroughly cleans and unclogs the interior of the filter cartridge 2025, restoring its filtration performance. The entire pulse assembly 202 operates in a highly automated and intelligent manner, enabling scheduled cleaning and dust removal without manual intervention. This design not only improves the equipment's operational efficiency and stability, but also reduces maintenance costs and labor intensity. Furthermore, the inclusion of the pulse assembly 202 elevates the dust removal performance of the present split-type sludge drying equipment to a higher standard, providing users with a cleaner and more efficient drying solution.

[0041] In addition, the jet pipe 2023 includes a gas collecting pipe 2021, multiple gas branch pipes 2022, multiple jet pipes 2023, and multiple jet nozzles 2024. The multiple gas branch pipes 2022 are respectively connected to the gas collecting pipe 2021, and the multiple jet pipes 2023 are respectively connected to the same gas branch pipe 2022. The gas outlet of the jet pipe 2023 is connected to the jet nozzle 2024, and the jet nozzle 2024 is connected to the air inlet of the filter cartridge 2025. The gas collecting pipe 2021 serves as the starting point of the entire jet pipe 2023 and is responsible for collecting high-pressure gas from an external gas source and evenly distributing it to each gas branch pipe 2022. The gas branch pipes 2022 are connected to the gas collecting pipe 2021 and are responsible for further distributing the high-pressure gas to the multiple jet pipes 2023, ensuring that each jet pipe 2023 receives sufficient gas. The jet pipes 2023 are core components of the jet line 2023. Their number corresponds to the number of gas distribution pipes 2022. Each jet pipe 2023 is connected to a jet nozzle 2024 at its outlet, which is directly aligned with the air inlet of the filter cartridge 2025. When the pulse assembly 202 is activated, high-pressure gas first enters the gas collection pipe 2021, is then distributed to each jet pipe 2023 via the gas distribution pipes 2022, and finally enters the filter cartridge 2025 at high speed through the jet nozzles 2024.

[0042] The design of the air nozzle 2024 is crucial. It not only needs to ensure that the high-pressure gas can be accurately injected into the air inlet of the filter cartridge 2025, but also needs to generate sufficient impact force during the injection process to effectively remove the dust layer on the surface of the filter cartridge 2025. Therefore, the shape, size, angle, and injection speed of the air nozzle 2024 all require careful design and adjustment.

[0043] In some embodiments, a heat pump mechanism 4 and a return air duct 5 are further included. The heat pump mechanism 4 is mounted on one side of the baking room mechanism 1. A gap is provided between the fixing plate 2026 and the filter cartridge 2025, allowing air from the lower chamber to enter the upper chamber through the gap. One end of the return air duct 5 is connected to the upper chamber, and the other end is connected to the heat pump mechanism 4. The heat pump mechanism 4 is cleverly mounted on one side of the baking room mechanism 1. It utilizes heat pump technology to boost heat energy from low-temperature heat sources (such as ambient air and waste heat) and reuse it in the drying process, thereby achieving energy recycling and energy conservation. The operation of the heat pump mechanism 4 not only reduces dependence on external heat sources (such as natural gas and electric heating), but also reduces operating costs and environmental impact.

[0044] In order to make full use of the thermal energy of the heat pump mechanism 4, this embodiment specifically leaves a certain gap between the fixed plate 2026 and the filter cartridge 2025. This gap allows the air in the lower cavity (i.e., the relatively clean air after being filtered by the filter cartridge 2025) to enter the upper cavity through natural convection or a slight fan action. In this way, the air temperature in the upper cavity will be relatively high and contain a certain amount of thermal energy, providing favorable conditions for the subsequent return air process. The return air duct 5 realizes the connection between the upper cavity and the heat pump mechanism 4. One end of the return air duct 5 is connected to the upper cavity and is responsible for collecting the hot air in the upper cavity; the other end is connected to the heat pump mechanism 4, and the collected hot air is sent to the heat pump mechanism 4 for heat recovery and reuse. Through the return air duct 5, the heat pump mechanism 4 can efficiently recover and utilize the thermal energy in the hot air, further improving the energy efficiency ratio and energy saving effect of the drying process.

[0045] Furthermore, the return air duct 5 is detachably connected to the dust removal mechanism 2, and the return air duct 5 is detachably connected to the heat pump mechanism 4. First, the connection between the return air duct 5 and the dust removal mechanism 2 adopts a detachable design. This design allows the user or technician to easily disassemble and reinstall the connecting parts between the return air duct 5 and the dust removal mechanism 2 when necessary. For example, when performing maintenance, replacement or upgrading of the dust removal mechanism 2, the user can first remove the return air duct 5 from the dust removal mechanism 2, and then perform the corresponding operation. After completion, the return air duct 5 can be reconnected to the dust removal mechanism 2. This detachable design not only simplifies the maintenance process, but also reduces maintenance costs and time. Secondly, the connection between the return air duct 5 and the heat pump mechanism 4 also adopts a detachable design. This design also provides flexible connection and disassembly methods, which is convenient for users or technicians to operate when maintaining, replacing or upgrading the heat pump mechanism 4. For example, if the heat pump mechanism 4 requires repair, the user can first remove the return air duct 5 from the heat pump mechanism 4 for more thorough inspection and maintenance. Once the repair is complete, the return air duct 5 can be reconnected to the heat pump mechanism 4 to restore normal operation of the device. More importantly, separating the return air duct 5 from the dust removal mechanism 2 and then from the heat pump mechanism 4 further facilitates transportation, eliminating any height or length restrictions and making packaging more convenient.

[0046] As an optional implementation, if height is limited but length is not, the return air duct 5 and the dust removal mechanism 2 are designed as an integral part, and the baking room mechanism 1 and the heat pump mechanism 4 are designed as an integral part. Simply put, the upper and lower parts are designed as two independent integrated modules, which are transported separately and then assembled on site. This effectively avoids the inconvenience caused by height restrictions during transportation.
