Description

Technical Field

[0001] The utility model relates to the technical field of pipeline arrangement in the field of intermittent displacement cooking, and in particular to a multifunctional reducing joint suitable for an intermittent displacement cooking boiler discharge pump. Background Art

[0002] The unloading of the cooking pot is the last step of the intermittent displacement cooking process. Unlike the traditional cooking method, since most of the heat in the cooking pot has been recovered through the washing filtrate displacement step before the cooking pot is discharged, the liquid in the pot cannot be sprayed under pressure after the temperature drops, and the unloading can only be done with the help of the discharge pump. Although the slurry temperature in the cooking pot has dropped below 100°C before unloading, the cooking pot is connected to the pressurized warm black liquid tank, so the equipment is under pressure at this time. Only after the discharge valve is opened will the pressure on the top of the pot drop to normal pressure rapidly. However, the discharge valve will cause a great impact on the discharge pipeline and the discharge pump at the beginning. The long-term vibration of the discharge pipeline will affect the life of the discharge pump.

[0003] Another factor that affects the life of the discharge pump is that the commodity chips entering the cooking pot are sometimes mixed with stones, metals or other hard debris. When making homemade chips, it is inevitable that they will fall into the parts of related equipment during slicing, screening and transportation. These things that enter the cooking pot will eventually enter the discharge pump through the discharge pipeline. If these hard debris are large, they will either damage the discharge pump or cause the pump shaft to bend and deform. Since the inlet pipeline diameter of the replacement cooking discharge pump is much larger than that of other process pipelines, it is generally not convenient to install a spare pump. Therefore, the economic loss caused by the impact of equipment maintenance on production is very large, and it is necessary to prevent large pieces of hard debris from entering the spray pot. Utility Model Content

[0004] The utility model aims to provide a multifunctional reducing joint suitable for an intermittent displacement steaming and boiling pot pump, which not only has the functions of shock absorption and intercepting large and hard debris, but also has the functions of a reducing joint and a sampler.

[0005] In order to achieve the above-mentioned invention object, the technical solution of the utility model is as follows:

[0006] A multifunctional reducing joint suitable for an intermittent displacement cooking boiler discharge pump comprises a boiler discharge pump pipe, a discharge pipe pipe and a short pipe, wherein the diameter of the short pipe is larger than the diameter of the boiler discharge pump pipe and the discharge pipe pipe, annular end plates are respectively arranged at both ends of the short pipe, the boiler discharge pump pipe and the discharge pipe pipe are respectively connected to the annular end plates at both ends, and the middle apertures of the annular end plates at both ends are respectively the same as the diameter of the boiler discharge pump pipe and the discharge pipe pipe; an observation hole is arranged at the top of the short pipe, the observation hole comprises a flange short-circuit and a flange blind plate, the pipeline end of the flange short-circuit is connected to the short pipe, and the flange end of the flange short-circuit is connected to the flange blind plate; a sampling port pipe is arranged at the bottom of the short pipe; a grille is arranged in the hollow part of the annular end plate on the boiler discharge pump pipe side.

[0007] The nominal diameter of the boiler discharge pump connecting pipe is smaller than the nominal diameter of the discharge pipe connecting pipe.

[0008] The length of the short pipe is 400-600 mm, and the diameter of the short pipe is 100-400 mm larger than the diameter of the discharge pipe.

[0009] The nominal diameter of the observation hole flange short circuit is DN200-DN400.

[0010] The grille is welded from a single or multiple round steels into a shape of I, II, a cross, a swastika, a well or a nine-square grid, and the round steel is welded on a circular end plate.

[0011] The material of the reducer is consistent with that of the discharge pipe.

[0012] The boiler discharge pump connecting pipe is connected to the boiler discharge pump inlet pipe through a flange, and the flange size and pressure level are consistent with the boiler discharge pump inlet connecting pipe.

[0013] The discharge pipe connecting pipe is connected to the discharge pipe through a flange, and the flange size and pressure level are consistent with those of the discharge pipe.

[0014] Beneficial effects of the utility model:

[0015] 1. The utility model has a simple and compact structure, is easy to manufacture, durable and has a low manufacturing cost; and can improve the adaptability and flexibility of the boiler pipeline layout.

[0016] 2. In the utility model, the diameter of the short pipe is designed to be larger than the boiler discharge pump connection pipe and the discharge pipe connection pipe. This structure is similar to a single corrugated expansion joint. When the pipeline is subjected to the pressure shock at the initial stage of boiler discharge, the end plates on both sides of the short connection undergo elastic deformation and squeeze inward. The resulting displacement can eliminate pipeline stress and play a shock-absorbing role.

[0017] 3. In the utility model, the observation hole arranged on the top of the short tube includes a flange short circuit and a flange blind plate. When there are debris intercepted in the short circuit, the operator can conveniently open the blind plate to observe the internal situation of the short tube and promptly remove the secondary large debris that cannot be removed by the sampling port.

[0018] 4. In the utility model, the sampling port is arranged at the bottom of the short tube, which is convenient for quick sampling when needed, and the sampling port is installed at the bottom of the short tube, which can block the obstructing debris at the bottom of the short tube to the maximum extent. When sampling is difficult, the debris blocking the bottom of the short tube can be found and removed in time to ensure smooth sampling.

[0019] 5. In the utility model, the grille provided on the annular end plate on the pipe side of the boiler pump can effectively prevent large impurities from entering the boiler pump and protect the pump body from damage. Various shapes of the grille (such as I-shaped, II-shaped, cross-shaped, swastika-shaped, well-shaped or nine-square-shaped) can be selected according to specific needs to achieve the best effect.

[0020] 6. In the utility model, the structural design of connecting the boiler discharge pump and the discharge pipeline through the flange facilitates the disassembly of the reducer, which is not only convenient for the maintenance of the boiler discharge pump, but also convenient for taking out large debris that cannot be taken out from the sampling joint and the observation hole.
