Description

Technical Field

[0001] This invention relates to a composite pressure sintering activated carbon equipment. Background Technology

[0002] In recent years, with the continuous expansion of resin types and application fields of polymer materials, polymer material molding and processing methods have gradually evolved from injection molding, extrusion molding, compression molding, calendering, hollow molding, and casting molding to new molding methods for products with special raw materials, special properties, and composite structures, as well as molding technologies for effectively controlling the aggregated structure of polymers. This includes auxiliary molding technologies specifically used for the sintering and molding of ultra-high molecular weight polyethylene and coconut shell activated carbon powder, and for partially hollow products. Due to the generally large molecular weight, the molecular chains are highly rigid. This causes the binder in ultra-high molecular weight polyethylene or other activated carbon molding products to remain in a gel state above its melting point, with melt viscosity approaching that of a solid, preventing the melt flow from reaching its optimal mode.

[0003] Continuous sintering of activated carbon rod filter cartridges offers high production capacity and good performance, but its drawbacks include the inability to continuously sinter non-standard activated carbon products such as non-cylindrical shapes, and the inability to control and adjust the sintering pressure in real time. Clogging can lead to insufficient filtration accuracy and waste of raw materials. Manual molding followed by furnace sintering allows for pressure and accuracy control, but it results in low production capacity, with each molded carbon rod requiring an average of over 3 hours to sinter. Furthermore, manual filling can cause inconsistencies in the precision of the finished product due to ash settling. Additionally, some non-standard activated carbon products (irregularly shaped activated carbon products such as activated carbon sheets and honeycomb activated carbon) cannot be produced using continuous molding machinery and still rely on traditional mold sintering, resulting in lower production capacity. Summary of the Invention

[0004] According to one aspect of the present invention, a composite pressure sintering activated carbon apparatus is provided, comprising: frame; Two forming dies are detachably mounted on the frame and cooperate to form a forming trough for receiving raw materials, so that a variety of forming troughs can be provided by replacing a variety of forming dies; A constant pressure device is used to drive the two molding dies to press against each other to pressurize the raw material in the molding tank; A heating device is used to heat the raw materials in the forming tank to sinter the raw materials into activated carbon products. The heating device includes a first heating component and a second heating component. The first heating component is configured to heat the raw materials in the forming tank inside the forming tank, and the second heating component is configured to heat the raw materials in the forming tank outside the forming tank. A heating drive device, wherein the output shaft of the heating drive device is connected to the first heating component via a heating connecting plate, and the heating drive device drives the first heating component to move in order to heat the raw material in the forming tank.

[0005] The composite pressure sintering activated carbon equipment of the present invention features two detachably mounted molding dies on a frame, allowing for the replacement of various molding dies to form different molding tanks as needed. During operation, a pressure regulating device drives the two molding dies on the frame to pressurize the raw material in the molding tank by mutual compression. Simultaneously, a heating device heats the raw material in the molding tank. This allows for simultaneous pressure and heating of the raw material in multiple molding dies, enabling continuous mechanical production of both standard and non-standard activated carbon products, thus improving production capacity.

[0006] In some embodiments, the pressure regulating device is used to drive the two molding dies to move relative to each other in a horizontal or vertical direction to cooperate in forming the molding groove to pressurize the raw material in the molding groove.

[0007] In some embodiments, a guiding device is also included, which is arranged along the horizontal or vertical direction of the frame, and the constant pressure device can drive the two forming dies to move relative to each other in the horizontal or vertical direction on the guiding device.

[0008] In some embodiments, two mold connectors are also included, the two molding dies being detachably mounted on the guide device via the two mold connectors, and the pressure regulating device is used to drive the two mold connectors to move relative to each other on the guide device in a horizontal or vertical direction.

[0009] In some embodiments, at least one of the two molding dies has a mounting hole, the number of which is matched with the number of the first heating element, and the first heating element can pass through the mounting hole to heat the raw material in the molding tank.

[0010] In some embodiments, a hopper is also included, one end of which passes through the two molding dies to form a feed port. The hopper is provided with a material cavity for storing raw materials and a feeding port. The hopper is configured to be able to move horizontally or vertically on the frame. When the hopper moves to the two molding dies, the feeding port and the feed port are aligned so that the raw materials in the material cavity can enter the molding dies through the feed port.

[0011] In some embodiments, a feeding valve is also included, which is used to restrict the opening and closing of the feeding port.

[0012] In some embodiments, a buffer is also included, which is disposed between the two molding dies to limit the two molding dies from pressing against each other. Attached Figure Description

[0019] In this specification, the illustrative expressions of the terms used do not necessarily refer to the same embodiments or examples. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of those different embodiments or examples, without contradiction.

[0020] Example 1: Please refer to Figure 1 This embodiment provides a composite pressure sintering activated carbon equipment, including a frame 10, a forming device, a pressure regulating device 20, a heating device, a guiding device 30, a hopper 100, a feeding valve, a buffer component 70, and a mold connecting assembly. Figure 1-2 In the coordinate system shown, the length direction of the frame 10 is defined as the X-axis direction, the width direction of the frame 10 is defined as the Y-axis direction, and the vertical (plumb) direction is defined as the Z-axis direction. The horizontal direction includes the X-axis direction and the Y-axis direction, and the X-axis, Y-axis and Z-axis directions are perpendicular to each other.

[0021] Please refer to Figure 1 The frame 10 is used to support the molding device, the pressure regulating device 20, the heating device, the guiding device 30, the hopper 100, the feeding valve, the buffer 70, and the mold connection assembly.

[0022] The molding device includes multiple molding die assemblies; please refer to [reference needed]. Figure 1 Each molding die assembly includes two molding dies. In each molding die assembly, the two molding dies are detachably mounted on the frame 10 and cooperate to form a molding trough for receiving raw materials. The molding dies can be standard dies or non-standard dies. Thus, standard molding troughs or non-standard molding troughs can be provided by replacing standard dies or non-standard dies.

[0023] For each molding die component, please refer to Figure 1 The two molding dies are a fixed die 80 and a moving die 90, which are symmetrically arranged along the length (X-axis) of the frame 10, or they can be symmetrically arranged along the width (Y-axis) of the frame 10. A fixed die forming part is formed on the side of the fixed die 80 facing the moving die 90, and a moving die forming part is formed on the side of the moving die 90 facing the fixed die 80. When the pressure-regulating device 20 is activated, it drives the moving die 90 to move towards the fixed die 80 and press against it, thus forming a molding groove by the fixed die forming part and the moving die forming part. This pressurizes the raw material in the molding groove, thereby forming standard and non-standard activated carbon products. Specifically, a single pressure-regulating device 20 can simultaneously drive the moving dies 90 in multiple molding die assemblies to press the fixed die 80, or multiple pressure-regulating devices 20 can separately drive multiple moving dies 90 to press multiple fixed dies 80. Of course, the fixed mold 80 can also be omitted, meaning both molding dies are movable molds 90. Two pressure-regulating devices 20 move the two movable molds 90 towards each other to achieve mutual compression. More specifically, the number of molded parts on each fixed mold 80 can be set to one or more, and the number of molded parts on the movable mold 90 can be matched accordingly. Thus, the fixed mold 80 and movable mold 90 can cooperate to form one or more molding grooves, meaning that one or more activated carbon products can be produced through each molding die assembly.

[0024] Specifically, please refer to Figure 1 The fixed molded parts and the moving molded parts can be irregularly shaped recesses or protrusions, thus forming non-standard molding grooves.

[0025] More specifically, please refer to Figure 1 The pressure regulating device 20 is preferably a cylinder, but it can also be a motor, hydraulic cylinder or other driving component.

[0026] In the molding process of standard and non-standard activated carbon products, the raw materials in the molding tank are heated by a heating device to achieve sintering and molding of the raw materials, that is, molding and sintering at the same time, which is conducive to the rapid production of activated carbon products and increases production capacity.

[0027] Specifically, please refer to Figure 2 The heating device includes a first heating element 50, which is configured to heat the raw material in the forming tank. That is, the first heating element 50 can heat the raw material from the forming tank, thereby increasing the contact area with the raw material, which is beneficial for the rapid heating of the raw material and improving the sintering efficiency.

[0028] More specifically, mounting holes may be provided on the fixed mold 80, please refer to... Figure 3 The mounting holes are located near the fixed mold forming part and extend along the width direction (Y-axis direction) of the frame 10 on the fixed mold 80. Alternatively, they can be arranged along the length direction (X-axis direction), vertical direction (Z-axis direction), or diagonally (XY-axis direction) of the frame 10. The number of mounting holes matches the number of first heating elements 50. In use, the first heating elements 50 can pass through the mounting holes and be installed within them to heat the raw material in the forming tank. Of course, the first heating elements 50 can be removed when not needed. In another embodiment, the mounting holes can be provided on the moving mold 90, or mounting holes can be provided on both the fixed mold 80 and the moving mold 90. This heating structure is particularly suitable for solid internal standard activated carbon products and non-standard activated carbon products.

[0029] A preferred embodiment includes a second heating element 60, which is configured to heat the raw material inside the forming tank from outside the forming tank. Specifically, the second heating element 60 is fitted onto the outer surface of the fixed mold 80 or the moving mold 90, or the second heating element 60 is fitted onto both the fixed mold 80 and the moving mold 90, thereby further heating the raw material inside the forming tank from outside the forming tank. More specifically, the second heating element 60 is preferably a heating coil, which generates heat when energized, thereby transferring heat to the raw material inside the forming tank.

[0030] In the molding process of standard activated carbon products and non-standard activated carbon products, the raw materials in the molding tank can be heated from the inside and outside by the action of the first heating element 50 and the second heating element 60, which greatly improves the sintering efficiency.

[0031] The sintering equipment also includes a guiding device 30, please refer to... Figure 1-6The guide device 30 is arranged along the width direction (Y-axis direction) of the frame 10, or it can be arranged symmetrically along the length direction (X-axis direction) of the frame 10. The fixed mold 80 is installed at one end of the guide device 30 and is maintained at a preset position in the width direction (Y-axis direction) of the frame 10. The pressure regulating device 20 can drive the moving mold 90 to move horizontally on the guide device 30 toward the fixed mold 80, so that the moving mold 90 can move to the fixed mold 80 and cooperate with the fixed mold 80 to form a molding groove, thereby enabling the pressure regulating device 20 to continuously pressurize the raw material in the molding groove. In some embodiments, the pressure regulating device 20 is adjustable. Specifically, the pressure regulating device 20 can keep the pressure of the raw material in the molding groove constant during sintering, or it can adjust multiple predetermined pressure values ​​according to the sintering process of the raw material in the molding groove, or the pressure regulating device 20 can be steplessly adjusted, thereby making the pressure range of the raw material in the molding groove during sintering 0.2-0.8 MPa.

[0032] The sintering equipment also includes two mold connectors 40, please refer to... Figure 1-6 The two mold connectors 40 are a fixed mold connector and a moving mold connector, respectively. The fixed mold 80 is detachably mounted on the fixed mold connector and held in a preset position in the width direction (Y-axis direction) of the frame 10. The output shaft of the constant pressure device 20 is connected to the moving mold connector, and the moving mold 90 is detachably mounted on the moving mold connector. The constant pressure device 20 drives the moving mold connector and the moving mold 90 to move horizontally towards the fixed mold 80 on the guide device 30. In specific implementation, the fixed mold 80 and the fixed mold connector, and the moving mold 90 and the moving mold connector can be locked together by threads. This arrangement facilitates the disassembly and assembly of the moving mold 90 and the fixed mold 80, thereby facilitating replacement.

[0033] The forming tank is a tank that is closed at the bottom and open at the top. Specifically, the top of the forming tank penetrates the top surface of the two forming molds, and a feed inlet is formed on the top surface. Specifically, the sintering equipment also includes a hopper 100. Please refer to [reference needed]. Figure 2 , 4 The hopper 100 is equipped with a material cavity for storing raw materials and a feeding port. The number of hoppers 100 is the same as that of the fixed molds 80, and they can move vertically (Z-axis direction) on the frame 10. When the hopper moves to the two forming molds, the feeding port and the inlet position correspond, so that the raw materials in the material cavity can enter the forming groove through the inlet. In specific implementation, the feeding drive device 120 drives the hopper 100 to move vertically (Z-axis direction) on the frame 10, which can complete the effective feeding. This can help improve the automation level of feeding and thus increase the production capacity. Of course, another guiding device 30 can also be set. The feeding drive device 120 is connected to the hopper 100 through the feeding connecting plate 170, so that the guiding device 30 is arranged vertically (Z-axis direction). The guiding device 30 plays a guiding role in the process of the feeding connecting plate 170 driving the hopper 100 to move.

[0034] Specifically, the feeding drive device 120 is preferably a cylinder, but it can also be a motor, hydraulic cylinder or other drive components.

[0035] The sintering equipment also includes a feeding valve, which is used to restrict the opening and closing of the feeding port, thereby achieving effective control of the feeding action.

[0036] To improve product quality, raw materials can be manually fed into mold 130. Please refer to [the relevant documentation]. Figure 5 , 6 Then, the mold 130 is placed into the molding tank for sintering. This allows the raw material to be evenly distributed in the molding tank and the product to be easily demolded.

[0037] For specific implementation, please refer to Figure 2-6 The first heating element 50 is preferably a heating rod, which facilitates manufacturing and disassembly. Please refer to... Figure 5 , 6 Such a first heating element 50 is particularly suitable for heating in the molding process of cylindrical (round or square) hollow carbon rods in standard activated carbon products. Specifically, after the material is added to the molding tank, the heating rod can be directly inserted into the feed port to install the heating rod in the molding tank, so that the raw material in the molding tank is molded into a cylindrical hollow carbon rod product. After sintering and molding, the moving mold 90 is reset, cooled and demolded, and the product can be taken out at this time. In another embodiment, the mold 130 includes a sleeve and a cover. The sleeve is a cylindrical structure for receiving raw materials, which is closed at one end and open at the other end. The cover is used to close the sleeve and has an installation port. After the material is manually added into the sleeve, the cover is placed on the sleeve, and the heating rod is installed on the cover through the installation port. Thus, the heating rod can be inserted into the raw material in the sleeve to heat the raw material.

[0038] A better implementation method is to refer to... Figure 2 The heating rod can move in the vertical direction (Z-axis direction). The sintering equipment may also include a heating drive device 160. The heating rod is installed above the fixed mold 80 and the number of fixed molds 80 is the same. The output shaft of the heating drive device 160 is connected to the heating rod through the heating connecting plate 110. After the material is fed, the material cavity of the hopper 100 is an empty cavity. The heating drive device 160 drives the heating rod to move down and enter the material cavity and the feeding port in sequence to heat the raw material in the forming tank.

[0039] Specifically, please refer to Figure 2 The heating drive device 160 is preferably a cylinder, but it can also be a motor, hydraulic cylinder or other drive components.

[0040] The sintering equipment also includes a buffer element 70, please refer to... Figure 1-6A buffer 70 is disposed between two molding dies to limit the mutual compression between the two molding dies. Specifically, the buffer 70 is disposed between the two die connectors 40. More specifically, the buffer 70 is preferably an elastic element, which can be a compression spring, tension spring, torsion spring, spring sheet, elastic rubber, elastic sponge, etc. In a specific implementation, the buffer 70 is a spring, and the guide device 30 includes two guide rods arranged along the width direction of the frame 10. The fixed mold connector and the moving mold connector slide on the guide rods respectively via sliders. The spring is fitted on the guide rod and placed between the fixed mold connector and the moving mold connector, providing a better buffering effect and helping to avoid wear caused by collision between the fixed mold 80 and the moving mold 90.

[0041] The manufacturing method of non-standard activated carbon products is as follows: Please refer to Figure 1-6 First, a certain amount of coconut shell activated carbon powder (80-200 mesh) and ultra-high molecular weight PE powder are mixed evenly according to the product pre-design conditions. Then, a non-standard mold is installed on the frame 10. The heating inner rod is placed in the hollow part of the sleeve mold 130. The mixed raw materials are filled into the sleeve mold 130. The pressure device 20 drives the moving mold 90 to move towards the fixed mold 80 to form a molding groove. The sleeve mold 130 is placed in the molding groove. After tight pressure is applied until the pressure reaches the set value, the heating coil is energized to heat to the set temperature and kept constant for about (15-20) minutes. After heating is stopped, the pressure device 20 is reset. After the moving mold 90 is disengaged, the sleeve mold 130 is taken out and air-cooled for demolding. The pressure is released and the product is taken out.

[0042] Similarly, the manufacturing method for standard activated carbon products is similar; please refer to [reference needed]. Figure 5 , 6 Simply install a standard mold on the frame 10.

[0043] This invention, in a continuously pressurized and controllable mode, allows for the setting of cylinder pressure values ​​based on the specific characteristics and requirements of the product during sintering. This ensures that the precision of the sintered activated carbon meets design requirements. In short, the sintering time and cylinder pressure and sintering coil temperature are set and adjusted simultaneously during sintering. This allows for simultaneous pressurization and sintering in an adjustable pressure mode. Each machine can accommodate at least 3-6 molds for simultaneous sintering. The product production sintering time is approximately one-quarter of that of manual mold-setting sintering at 130°C (240 minutes). The energy consumption of manual mold-setting sintering at 130°C is approximately 45 kWh / 100 pieces, while the energy consumption of the composite pressure sintering machine used in this invention is approximately 15 kWh / 100 pieces. Therefore, this invention consumes far less manpower and energy than the manual mold-setting sintering at 130°C. In particular, the precision control of the product of this invention is more convenient and accurate than that of continuous sintering. If 20-30 of these machines are installed, the production capacity and labor costs will be more advantageous compared with the existing technology. The molds are used less and have a fast turnover, and can be used for most sintering molds of most diameters. Furthermore, the sintering furnace has a large power consumption, while the power consumption of the coil sealing heating method of this invention is smaller, saving energy and reducing environmental pollution.

[0044] Example 2: This embodiment provides another composite pressure sintering activated carbon equipment. The main difference between this embodiment and Embodiment 1 is: This sintering equipment is mainly used for producing standard activated carbon products. Please refer to [link / reference]. Figure 7-9 The constant pressure device 20 is used to drive the two forming molds to move relative to each other in the vertical direction (Z-axis direction) to form a forming groove to pressurize the raw material in the forming groove. That is, the moving mold 90 and the fixed mold 80 mentioned above serve as the upper mold 140 and the lower mold 150, respectively. Multiple upper molds 140 and lower molds 150 (filter cartridges) are respectively provided on the two mold connecting parts 40, with the same number and corresponding positions.

[0045] Specifically, please refer to Figure 7-9 The guide device 30 is arranged along the vertical direction (Z-axis direction) of the frame 10. The lower mold 150 is installed on the lower end of the guide device 30, i.e., on the frame 10. The pressure regulating device 20 can drive the upper mold 140 to move towards the lower mold 150 on the guide device 30. The upper mold 140 can move to the lower mold 150 and cooperate with the lower mold 150 to form a forming groove, so that the pressure regulating device 20 can continuously pressurize the raw material in the forming groove.

[0046] More specifically, this sintering equipment is particularly suitable for standard activated carbon products; please refer to [reference needed]. Figure 7-9Both the upper mold 140 and the lower mold 150 are hollow cylindrical structures. The hopper 100 is integrated into the upper mold connector. The feeding port is formed by the top surface of the hopper 100 penetrating the bottom surface of the upper mold 140. The outer diameter of the upper mold 140 is smaller than the diameter of the lower mold 150. That is, as the upper mold 140 slides on the guide device 30, the hopper 100 can move synchronously, so that the upper mold 140 can be inserted into the lower mold 150. The feeding valve is opened, and the raw material enters the lower mold 150 from the feeding port. After the feeding is completed, the feeding valve closes the bottom surface of the upper mold 140. The upper mold 140 continues to descend to pressurize the raw material in the forming groove, so that the raw material in the forming groove is formed into a cylindrical hollow carbon rod product.

[0047] The first heating element 50 is a heating rod; please refer to... Figure 7-9 After the material is added to the forming tank, the heating rod can be directly inserted into the feeding port to install it inside the hollow structure of the upper mold 140. This heats the material inside the forming tank. The second heating element 60 is arranged around the outer circumference of the lower mold 150, thereby pressing and heating the material inside the forming tank to form a cylindrical hollow carbon rod product. After sintering, the upper mold 140 is reset, cooled, and demolded, at which point the product can be removed.

[0048] A preferred implementation is that the heating rod can move in the vertical direction (Z-axis direction), specifically in two ways: The first method involves installing the heating rod above the upper mold 140. Please refer to [the relevant documentation]. Figure 7 The output shaft of the feeding drive device 120 is connected to the heating rod through the heating connection plate 110. After feeding, the material cavity of the hopper 100 is empty. The heating drive device 160 drives the heating rod to move down and enter the material cavity and feeding port in sequence to heat the raw material in the forming tank.

[0049] The second method involves installing the heating rod below the lower mold 150. Please refer to [the relevant documentation]. Figure 8 The output shaft of the feeding drive device 120 is connected to the heating rod through the heating connecting plate 110. An installation port is formed between the lower mold 150 and the frame 10. The installation port is concentric with the feed port. The heating drive device 160 drives the heating rod to move upward. The heating rod passes through the installation port and closes the installation port. The heating rod enters the forming groove. The upper mold 140 moves downward and enters the lower mold 150. The raw material enters the lower mold 150 from the feeding port. After feeding is completed, the feeding port is closed. The upper mold 140 continues to move downward and abuts against the heating rod, thereby realizing the heating of the raw material in the forming groove.

[0050] In another embodiment, please refer to Figure 9 The first heating element 50 and the second heating element 60 are both heating coils, that is, the first heating element 50 is wound around the outer peripheral surface of the upper mold 140 to heat the raw material in the forming groove.

[0051] The manufacturing method of standard activated carbon products (conventional cylindrical or square hollow carbon rod products) is as follows: First, a certain amount of coconut shell activated carbon powder (80-200 mesh) and ultra-high molecular weight PE powder are mixed evenly according to the pre-designed product specifications. This mixture is then filled into hopper 100. The pressure-regulating device 20 drives the upper mold 140 downwards to connect the feeding port with the inlet of the filter cartridge barrel. The feeding port opens, and the raw material falls into the corresponding filter cartridge barrel. After filling, the inlet closes. Under the action of the upper mold 140, the raw material in the filter cartridge barrel reaches a certain pressure value, and the pressing ends. Simultaneously, the heating device starts working, heating to the set temperature and maintaining it for approximately 10 minutes. At the same time, the pressure-regulating device 20 slowly drives the upper mold 140 to apply pressure to the raw material in the molding tank until the pressure reaches the set pressure. Then, the temperature and pressure are maintained for a certain time (15-20 minutes). After heating stops, the movable upper mold 140 is moved upwards, the heating device stops heating, and the air-cooling device quickly cools and demolds the product. The pressure is released, and the product is removed. The next batch of pre-treated barrels is pushed in and fixed. This cycle ends, and the raw material is added to the mold barrel for the next cycle.

[0052] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
