Description

Technical Field

[0001] This utility model relates to the field of ceramic tile production equipment, and in particular to a fuel supply device for ceramic tile production. Background Technology

[0002] In the ceramic tile production process, the firing stage after the tile blanks are formed is of paramount importance, directly affecting the quality, performance, and appearance of the tiles. Common fuels used for firing ceramic tiles include heavy oil, kerosene, and natural gas. Among these, heavy oil, as an important industrial fuel, has unique advantages. Heavy oil is the residual heavy oil after extracting gasoline and diesel from crude oil; it has high energy density and a relatively stable supply. In particular, heavy oil is relatively inexpensive, reducing costs, and has a high combustion temperature. For large-scale ceramic tile production, this can meet the stringent high-temperature requirements of the firing process, providing sufficient heat for the series of physical and chemical changes that occur during firing. This ensures that the tiles possess good hardness, density, and stability, making it one of the important fuel choices for ceramic tile firing.

[0003] The reason why heavy oil has a high viscosity and poor fluidity is that it contains relatively high levels of gums and asphaltenes, which makes its internal structure more compact and hinders the free movement of molecules within the heavy oil, resulting in poor fluidity. In practical applications, to ensure the pumping and complete combustion of heavy oil, it must be heated before use to intensify the thermal motion of its internal molecules, reduce its viscosity, and improve its fluidity. During the pumping process, pressurized extraction pumps are typically used to transport the oil through pipelines. However, the problem of excessively high viscosity remains prominent during transport, requiring pumps with more powerful motors, consuming significant electrical energy, and severely limiting pumping efficiency, thus significantly impacting production progress. Furthermore, during pumping, impurities, colloids, and localized solidification due to temperature changes easily adhere to and accumulate on the inner walls of pipelines, impellers, valves, and other critical components of the pumping equipment, gradually forming blockages and easily causing clogging problems. According to statistics, on ceramic tile production lines using heavy oil as fuel, clogging of the heavy oil pumping equipment requires an average of 2-3 shutdowns per week for maintenance, with each repair lasting from several hours to a full day. This not only increases maintenance costs but also causes frequent production line interruptions, significantly impacting ceramic tile production efficiency and output, resulting in substantial economic losses.

[0004] To address the challenges of heavy oil pumping, the industry has implemented various measures, but these methods still have significant limitations. Currently, the most common methods for improving heavy oil flowability are heating and adding diluents. Heating involves increasing the temperature of the heavy oil by installing steam tracing pipes in the pipeline, thereby reducing its viscosity. This method requires the construction of a heating station, necessitating substantial investment. Furthermore, during long-term use, the heating pipes are susceptible to corrosion from impurities and chemicals in the heavy oil, leading to pipeline damage and frequent repairs or replacements. Additionally, coking can occur within the pipeline, affecting heat transfer efficiency and potentially causing blockages and shutdowns. The diluent addition method involves blending light oils, such as condensate oil or naphtha, into heavy oil. Utilizing the principles of "like dissolves like" and dilution, this reduces the concentration of asphaltenes and gums in the heavy oil, thereby lowering viscosity and improving fluidity. However, the diluent method also has its drawbacks. The added thinner needs to be separated by distillation at the final stage and returned to the starting point for recycling. This process involves investment in distillation equipment, energy consumption, and the construction and maintenance of pipelines, significantly increasing the complexity and cost of the entire production process.

[0005] In summary, while the aforementioned countermeasures can alleviate the problems in the heavy oil pumping process to some extent, they do not fundamentally solve the issues of low pumping efficiency, high investment costs, complex maintenance, and high maintenance costs, and cannot meet the needs of tile manufacturers for efficient, stable production and low-cost operation. Utility Model Content

[0006] The purpose of this invention is to solve the above problems and provide a fuel supply device for ceramic tile production that has high pumping efficiency, simple and compact structure, easy maintenance, stable production, and low-cost operation.

[0007] The technical solution of this utility model is implemented as follows: A fuel supply device for ceramic tile production, characterized in that it includes a rectangular support platform; a servo motor arranged longitudinally along the length of the support platform at the rear end of the support platform; and a screw booster feeding mechanism arranged longitudinally along the length of the support platform at the front end of the support platform. The screw booster feeding mechanism consists of a tubular shell with an inlet pipe interface and an outlet pipe interface, and a screw disposed in the tubular shell. The screw is drivenly connected to the servo motor. An auxiliary pressurizing and pushing mechanism between the servo motor and the screw pressurizing and feeding mechanism comprises a flat housing with an inlet and an outlet, a piston pusher plate disposed within the flat housing, and electric push rods disposed on both sides of the flat housing. The piston pusher plate is connected to the electric push rods on both sides to make the piston pusher plate reciprocate within the flat housing. The inlet is connected to the feed pipe interface, and the outlet is connected to the transmission connection between the screw and the servo motor to pressurize and push fuel from the transmission connection into the tubular housing.

[0008] Furthermore, the present invention also includes a flame arrester, which consists of a metal housing and a flame arrester filter element disposed in the metal housing. The metal housing has a feed port and a discharge port, and the feed port is connected to the discharge pipe interface.

[0009] Furthermore, the tubular shell is provided with a first connecting end piece and a second connecting end piece at both ends, and a plurality of fixed tie rods are provided between the first connecting end piece and the second connecting end piece, which surround the tubular shell.

[0010] Furthermore, the first connecting end piece is also connected to a feed pipe, and the feed pipe interface is vertically arranged on the outer wall of the feed pipe so that the feed pipe interface and the feed pipe form a T-shaped structure.

[0011] Furthermore, one end of the feed inlet is connected to the outer wall of the feed pipe interface, and the other end of the feed inlet is vertically connected to the flat housing; and a one-way check valve structure is also provided in the feed inlet.

[0012] This utility model's fuel supply device for ceramic tile production achieves significant technical advantages through a multi-mechanism collaborative design: the servo motor-driven screw pressurizing feeding mechanism and the auxiliary pressurizing pushing mechanism form a dual power output, enabling continuous and stable feeding via the screw and secondary pressurization via the piston pusher plate, greatly improving pumping efficiency, especially suitable for the efficient delivery of high-viscosity fuels, avoiding delivery interruptions.

Each mechanism adopts a modular design; components such as tubular shells and flat shells are easy to disassemble and clean, and key components such as electric push rods and screws are easy to maintain, reducing operation and maintenance costs. The dual pressurization mechanism ensures stable fuel supply pressure, providing continuous and reliable energy support for ceramic tile production and ensuring production continuity. At the same time, the servo motor and electric push rod drive method has low energy consumption, and combined with the simple mechanical structure, it significantly reduces equipment operation and maintenance costs, achieving low-cost and stable operation.

A rectangular support platform 1 is adapted to the longitudinal layout of the production line, providing a stable installation foundation for each component. The components are arranged in an orderly manner according to their functions, saving space and helping to make the overall structure of the device compact. It also facilitates the positioning and movement of the equipment in the workshop.

[0019] A servo motor 2 is arranged longitudinally along the length of the support platform 1 at the rear end of the support platform 1.

[0020] A screw-driven pressurized feeding mechanism 3 is arranged longitudinally along the length of the support platform 1 at the front end of the support platform 1. The screw-driven pressurized feeding mechanism 3 consists of a tubular housing 31 with an inlet pipe interface 33 and an outlet pipe interface 34, and a screw 32 disposed in the tubular housing 31. The screw 32 is connected to a servo motor 2 for transmission. It is arranged longitudinally along the support platform, which is suitable for the overall layout and saves space. Using the screw 32 and the servo motor 2 as the main feeding mechanism can stably pressurize and feed materials, ensuring fuel supply efficiency and pressure stability.

[0021] An auxiliary pressurizing and pushing mechanism 4 is provided between the servo motor 2 and the screw pressurizing and feeding mechanism 3. The auxiliary pressurizing and pushing mechanism 4 consists of a flat housing 41 with an inlet 411 and an outlet 412, a piston push plate 42 provided in the flat housing 41, and electric push rods 43 provided on both sides of the flat housing 41. The piston push plate 42 is connected to the electric push rods 43 on both sides so that the piston push plate 42 reciprocates in the flat housing 41. The inlet 411 is connected to the feed pipe interface 33, and the outlet 412 is connected to the transmission connection between the screw 32 and the servo motor 2 so as to pressurize and push fuel from the transmission connection into the tubular housing 31. The auxiliary pressurizing and feeding mechanism 4 is positioned between the servo motor 2 and the screw pressurizing and feeding mechanism 3, making the overall structure more compact and saving space. The flat housing 41, together with the piston push plate 42 and the electric push rod 43, pressurizes and pushes the material through reciprocating motion, forming secondary pressurization, which greatly improves the pumping efficiency, especially suitable for the efficient transportation of high viscosity fuels, and avoids transportation interruption.

[0022] like Figure 1 and Figure 5 As shown, this utility model also includes a flame arrester 5, which consists of a metal housing 51 and a flame-arresting filter element 52 disposed within the metal housing 51. The metal housing 51 has a feed port 511 and a discharge port 512, with the feed port 511 connected to the discharge pipe interface 34. The metal housing 51 provides robust protection and, together with the flame-arresting filter element 52, forms a reliable flame-arresting structure, effectively blocking flame propagation and ensuring safe fuel delivery. The feed port 511 is connected to the discharge pipe interface 34, achieving a tight connection with the feeding mechanism, ensuring an intact fuel delivery path, and improving the safety performance of the device while reducing the risk of fire without affecting supply efficiency.

[0023] like Figure 1 and Figure 2As shown, the tubular shell 31 is further provided with a first connecting end piece 35 and a second connecting end piece 36 at both ends. Multiple fixing rods 37 are also provided between the first connecting end piece 35 and the second connecting end piece 36, encircling the tubular shell 31. The discharge pipe interface 34 is located on the second connecting end piece 36. The use of multiple encircling fixing rods 37 enhances the connection strength between the two ends, reinforces the overall structure of the tubular shell 31, resists the internal pressure during screw feeding, reduces deformation, ensures long-term stable operation of the device, and improves structural reliability.

[0024] like Figure 1 and Figure 2 As shown, the first connecting end piece 35 is also connected to a feed pipe 6. The feed pipe interface 33 is vertically disposed on the outer wall of the feed pipe 6, so that the feed pipe interface 33 and the feed pipe 6 form a T-shaped structure. The feed pipe interface 33 is vertically disposed on the outer wall of the feed pipe 6 to form a T-shaped structure, so that the fuel of the auxiliary pressurizing and pushing mechanism can be vertically integrated into the main conveying channel, reducing flow resistance, improving feeding continuity, and the compact layout saves space.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, one end of the feed inlet 411 is connected to the outer wall of the feed pipe interface 33, and the other end of the feed inlet 411 is perpendicularly connected to the flat shell 41. A one-way check valve structure 44 is also provided in the feed inlet 411. The feed inlet 411, with one end connected to the outer wall of the feed pipe interface 33 and the other end perpendicularly connected to the flat shell 41, forms a smooth fuel delivery path, reducing flow resistance and ensuring efficient fuel entry into the flat shell 41. The built-in one-way check valve structure 44 prevents the pressurized fuel in the flat shell 41 from flowing back, ensuring stable unidirectional fuel delivery to the tubular shell 31, avoiding feed interruptions, and improving supply reliability.

[0026] like Figure 4 As shown, the one-way check valve structure 44 consists of a conical cavity wall 441 disposed in the inner cavity of the feed inlet 411, a ball bearing 442 fitted onto the conical cavity wall 441, a return spring 443 resting on the ball bearing 442, and a spring support frame 444 disposed at the bottom end of the conical cavity wall 441. The conical cavity wall 441 and the ball bearing 442 cooperate to form a tight seal, which can effectively block the reverse flow of fuel; the return spring 443 and the spring support frame 444 work together to make the ball bearing 442 automatically open under the positive pressure of fuel and quickly return to its original position when there is no pressure, ensuring smooth one-way flow. The structure is simple and reliable, ensuring the pressurization efficiency and feeding stability of the auxiliary pressurizing and pushing mechanism.

[0027] like Figure 1 , Figure 3 , Figure 4As shown, the flat-lying housing 41 is also provided with an exhaust pipe 45, and a filter screen 46 is provided at the port of the exhaust pipe 45. The exhaust pipe 45 can timely discharge the gas generated in the fuel conveying process inside the flat-lying housing 41, avoiding gas stagnation that could lead to unstable feeding pressure and affect feeding efficiency; the port filter screen 46 can prevent external dust and impurities from entering the housing and contaminating the fuel.

[0028] like Figure 2 As shown, a transmission shaft 7 is also provided between the screw 32 and the servo motor 2. The transmission shaft 7 sequentially passes through the center of the flat housing 41, the piston push plate 42, and the feed pipe 6. The discharge port 412 of the flat housing 41 is connected to the end of the feed pipe 6. By passing through the center of the flat housing 41, the piston push plate 42, and the feed pipe 6, the transmission connection between the servo motor 2 and the screw 32 is realized, ensuring efficient power transmission. The discharge port 412 of the flat housing 41 is connected to the feed pipe 6. Combined with the layout of the transmission shaft, the fuel pushing path and the power transmission path are compactly integrated, saving space. At the same time, the high-speed rotating transmission shaft 7 also has a clearing function to prevent sticky fuel from causing blockage and improve the continuity of feeding.

[0029] like Figure 4 As shown, the flat-lying housing 41 comprises a main chamber 47, secondary chambers 48 disposed on both sides of the main chamber 47 and communicating with each other, and end caps 49 disposed at both ends of the main chamber 47 and the secondary chambers 48. The electric push rod 43 is disposed in the secondary chamber 48, and the piston push plate 42 is disposed in the main chamber 47, with both sides of the piston push plate 42 extending into the secondary chambers 48 and connecting to the piston rod 431 of the electric push rod 43. The through-flow design of the main chamber 47 and the secondary chamber 48 provides independent installation space for the piston push plate 42 and the electric push rod 43, resulting in a compact layout. The piston push plate 42 extends into the secondary chambers 48 on both sides and connects to the piston rod 431, ensuring uniform transmission of thrust and improving material pushing stability. The end caps 49 seal both ends, ensuring the sealing performance inside the housing. The overall structure enhances material pushing efficiency and operational reliability.

[0030] like Figure 4 As shown, the main chamber 47 is also provided with a limiting ring 50 to limit the reciprocating motion of the piston push plate 42. The limiting ring 50 can precisely limit the reciprocating motion range of the piston push plate 42, avoid the push plate from colliding with the inner wall of the housing or other components due to excessive stroke, reduce wear, and extend the service life of the push plate and the housing; 2. At the same time, it ensures that the push plate always moves within the effective pushing range, ensures a stable pushing amount each time, avoids uneven feeding due to stroke deviation, and improves the operational stability and feeding accuracy of the auxiliary pressurizing pushing mechanism.
