Description

Technical Field

[0001] The utility model discloses a convenient sewage treatment device, which relates to the technical field of water circulation filtration. Background Art

[0002] Scaling in industrial cooling water circulation systems is a common problem that affects equipment operation. It usually leads to a series of problems such as increased equipment vibration, reduced work efficiency, and increased operating energy consumption, which seriously affects the continuous operation and energy efficiency of the equipment. Most heat exchange equipment surfaces and the inner walls of fluid delivery pipelines have fouling problems to varying degrees. On the one hand, equipment scaling reduces the heat transfer rate and increases fuel costs; on the other hand, it often causes a decrease in mechanical properties due to local overheating or high temperature, and in severe cases, it can cause production accidents. Pipeline scaling reduces the flow area of ​​the meson, increases the energy consumption of the delivery pump, reduces production efficiency, shortens the life of the pipeline, and corrosion brings problems such as running, bubbling, dripping, and leakage.

[0003] At present, the main methods for water circulation pipelines are to use traditional mechanical cleaning or chemical agents to solve the scaling problem of water circulation pipelines, that is, to use high-pressure jets or add scale inhibitors to remove scale. The efficiency of mechanical cleaning is low, and the descaling effect is difficult to guarantee. The use of chemical agents not only increases the operating cost of the system, but also accelerates the aging and corrosion of the pipeline, which in turn leads to safety accidents, serious economic losses and social problems. Summary of the invention

[0004] The purpose of the utility model is to design a convenient sewage treatment device capable of cleaning impurities such as scale in a pipeline.

[0005] The utility model comprises a housing, the upper part of which is provided with a water outlet pipe, and the lower part of which is provided with a water inlet pipe;

[0006] A filter mechanism is arranged in the housing and located between the water outlet pipe and the water inlet pipe; the filter mechanism comprises a group of porous plates with filter holes connected by studs and arranged at intervals from top to bottom;

[0007] The positioning mechanism of the filter mechanism includes nuts arranged above and below each porous plate and screwed to the studs, and also includes a slot arranged on the inner wall of the housing, the slot is located below the lowest porous plate, and a retaining ring is arranged therein to cooperate with the lowest porous plate;

[0008] The sedimentation chamber is located below the water inlet pipe, and a sewage outlet is arranged at the lower end thereof. An end cover is screwed on the sewage outlet, and a sealing ring is arranged between the end cover and the sewage outlet.

[0009] Furthermore, the inner cavity of the shell is a different-diameter pipe that is thin at the top and thick at the bottom, and its diameter-changing step surface is arranged on the inner wall of the shell below the water outlet pipe, and the uppermost porous plate is arranged below the step surface.

[0010] Furthermore, in the filtering mechanism, the aperture of the filtering holes on the upper porous plate is larger than the aperture of the filtering holes on the lowest porous plate.

[0011] Furthermore, the structures of the porous plates located at the top are the same.

[0012] The utility model provides a sedimentation chamber at the lower end of the filter mechanism, and impurities filtered out by the porous plate will settle into the sedimentation chamber due to their own gravity, thus preventing scale impurities from scaling in the pipeline and causing damage to the pipeline; when cleaning impurities, the filtered impurities can be taken out by unscrewing the end cover at the lower end of the sedimentation chamber, which is convenient to use; the filter mechanism is fixed by a retaining ring, and when replacement is required, the retaining ring can be clamped to take out the entire filter mechanism, which is convenient to clean.

[0019] by Figure 1 The up, down, left, right, front and back directions of this embodiment are defined as shown.

[0020] As shown in the figure, this embodiment includes a housing 1 , a filtering mechanism, a positioning mechanism of the filtering mechanism and a sedimentation chamber 2 .

[0021] In this embodiment, a water outlet pipe 3 is welded on the upper part of the housing 1, and a water inlet pipe 4 is welded on the lower part, and both the water outlet pipe 3 and the water inlet pipe 4 are communicated with the inner cavity 5 of the housing 1. The inner cavity 5 is arranged inside the housing 1, and the upper end is thinner, and a step surface is provided at the position where the inner diameter changes, and the position of the step surface is lower than the water outlet pipe 3. When in use, the filter mechanism is arranged below the step surface, which plays a role in limiting the filter mechanism.

[0022] In this embodiment, the filter mechanism is arranged in the housing 1, between the water outlet pipe 3 and the water inlet pipe 4, and includes a group of porous plates 6. In this embodiment, 6 porous plates 6 are arranged, and each porous plate 6 is arranged at intervals along the axial direction of the stud 7. The porous plates 6 are provided with filter holes for filtering scale impurities in the pipeline.

[0023] In this embodiment, the diameter of the central hole of the porous plate 6 is larger than the diameter of the stud 7, so that damage caused by contact and collision with the threads on the outside of the stud 7 can be avoided during sleeve connection.

[0024] In this embodiment, the filter hole diameters of the upper porous plates 6 are larger than the filter hole diameters of the lowest porous plates 6, and the structures of the upper porous plates 6 are the same, which can increase the flow rate of the filtered liquid.

[0025] When the porous plate 6 uses an alloy material mainly composed of copper, zinc and nickel, the alloy material will play a special catalytic role when in contact with the liquid, causing the electrostatic kinetic potential of the contacted fluid to change, thereby changing the binding force field between various substance molecules in the fluid, making the solid phase particles in a suspended and dispersed state, and inhibiting the formation of wax and scale in the liquid after filtration.

[0026] The positioning mechanism of the filter mechanism in this embodiment includes nuts 8, which are arranged above and below the porous plates 6, and are screwed with the studs 7 to clamp and fix the porous plates 6. When fixing the porous plates 6, the spacing between the porous plates 6 and the number of the porous plates 6 can be controlled by adjusting the position of the nuts 8 on the studs 7. A retaining ring 9 is arranged at the lower end of the lowest-level porous plate 6, and the retaining ring 9 is fixed by a slot opened at the lower end of the inner cavity 5. When installing, the retaining ring 9 is clamped by a circlip pliers and placed in the slot, which plays a role in supporting and limiting the filtering mechanism.

[0027] In this embodiment, a sedimentation chamber 2 is provided below the inner chamber 5, a sewage outlet is provided at the lower end of the sedimentation chamber 2, an end cap 10 is screwed to the lower end of the sedimentation chamber 2 through a thread, and a sealing ring 11 is placed in the end cap 10 to ensure the sealing effect of the sedimentation chamber 2. During use, scale impurities filtered out by the porous plate 6 are precipitated onto the end cap 10 by their own weight, and the end cap 10 can be removed by twisting it when cleaning is required.

[0028] When installing the utility model, firstly, the porous plate 6 with a small filter hole diameter is sleeved on the lower end of the stud 7, and the remaining porous plates 6 are installed in sequence after being fixed by the nut 8. After the installation is completed, the lowest-level porous plate 6 is placed on the upper end of the retaining ring 9, and the retaining ring 9 is clamped by the circlip pliers to put the installed porous plate 6 and the retaining ring 9 into the inner cavity 5 through the sedimentation chamber 2, and the retaining ring 9 is fixed by the card groove of the inner cavity 5, and then the end cover 10 is tightened to connect the water outlet pipe 3 and the water inlet pipe 4 to the pipeline.

[0029] When in use, after the liquid flows through the filter device, scale impurities will be filtered out through the porous plate 6, and the impurities will settle to the upper end of the end cover 10 by their own weight. When cleaning is needed, the end cover 10 is unscrewed to clean the settled impurities. When the filter mechanism needs to be cleaned and replaced, the end cover 10 is opened, and the snap ring pliers are inserted into the sedimentation chamber 2 to clamp the retaining ring 9 to remove the filter mechanism.
