Description

Technical Field

[0001] The utility model specifically relates to a mud suction device capable of filtering impurities for industrial sludge treatment. Background Art

[0002] Sludge is a solid sediment produced by the water and sewage treatment process; its main characteristics are: high water content, high organic matter content, easy to decompose and stink, and fine particles, small specific gravity, and colloidal liquid; industrial wastewater sludge and water supply sludge are one of the sources of sludge, and the disposal and treatment of industrial sludge has become a chronic disease restricting urban development and urban sanitation; with the strengthening of national energy conservation and emission reduction efforts, the improvement of national environmental protection awareness, and the increasing production of urban sludge, sludge disposal and development and utilization have become an important issue in environmental protection work.

[0003] Industrial sludge is discharged into the sedimentation tank along with sewage and settles in the sedimentation tank. Industrial sludge settles at the bottom of the sedimentation tank under the action of gravity. The working principle of traditional sludge suction equipment is to use a sludge suction pump to extract the air in the pipe, so that a relative vacuum is formed in the pipe. The lower end of the pipe is set near the bottom of the sedimentation tank. The sludge at the bottom of the tank is sucked into the siphon pipe system and then sent to a centralized treatment area for treatment. However, in actual operation, the sludge suction pump pipe is often blocked, which makes it impossible to effectively clean the industrial sludge at the bottom of the sedimentation tank. Utility Model Content

[0004] The utility model aims to address the deficiencies of the prior art and to provide a sludge suction device capable of filtering impurities for industrial sludge treatment, so as to achieve the purpose of cutting and dispersing condensed industrial sludge, improving sludge discharge efficiency, blocking large particles of impurities from entering the auxiliary sludge suction pipe and filtering impurities.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The utility model provides a mud suction device capable of filtering impurities for industrial sludge treatment, comprising a main mud suction pipe which is radially arranged, located in a sedimentation tank and connected to a mud suction pump through a connecting pipe, the main mud suction pipe having a hollow inner cavity, the main mud suction pipe having a plurality of evenly arranged auxiliary mud suction pipes radially arranged, the auxiliary mud suction pipes having a hollow inner cavity and connected to the main mud suction pipe, one end of the auxiliary mud suction pipe away from the main mud suction pipe being open, and a blocking component which plays a cutting and filtering role on coagulated sludge being arranged at the upper opening of the auxiliary mud suction pipe.

[0007] By adopting the above technical solution, the sludge suction pump provides power, so that the industrial sludge in the sedimentation tank enters the auxiliary sludge suction pipe, the main sludge suction pipe and the connecting pipe in turn to be collected. When the industrial sludge or large-particle impurities enter the auxiliary sludge suction pipe, the large-particle impurities are blocked by the blocking component, and the condensed industrial sludge is also cut, so that the condensed industrial sludge is dispersed, reducing the possibility of large-particle impurities and condensed industrial sludge clogging the main sludge suction pipe, the auxiliary sludge suction pipe and the connecting pipe, and also reducing the possibility of condensed industrial sludge not being discharged, thereby improving the working efficiency of the device without affecting the use of the device.

[0008] Preferably, the blocking assembly includes a connecting cover that is sleeved on the open end of the auxiliary mud suction pipe and threadedly connected to the auxiliary mud suction pipe. The connecting cover is provided with a plurality of circular grooves. A cutting tube that is adapted to the circular groove is integrally formed in each of the circular grooves. The inner cavity of the cutting tube is hollow and open at both ends. The end of the cutting tube away from the auxiliary mud suction pipe is a knife edge.

[0009] Through the above technical solution, when the coagulated sludge contacts the connecting cover and enters the auxiliary sludge suction pipe, the coagulated industrial sludge is cut by the cutting pipe, so that the coagulated industrial sludge is dispersed to facilitate the discharge of the coagulated sludge and prevent the coagulated sludge from clogging the auxiliary sludge suction pipe.

[0010] Preferably, the cutting pipe is arranged obliquely, the end of the cutting pipe away from the auxiliary mud suction pipe is inclined, and the distance between point A of the cutting pipe and the connecting cover is greater than the distance between point B of the cutting pipe and the connecting cover.

[0011] Through the above technical solution, since the cutting pipe is set obliquely, the efficiency of the cutting pipe in cutting the coagulated industrial sludge is improved, and the strength and service life of the device are improved.

[0012] Preferably, the auxiliary mud suction pipe is provided with a filtering component for further filtering impurities.

[0013] Through the above technical solution, by setting up a filter assembly, impurities are further filtered, and the possibility of the main mud suction pipe being blocked is further reduced.

[0014] Preferably, the filter assembly includes a filter tube integrally formed with the auxiliary mud suction pipe, the center line of the filter tube is perpendicular to the center line of the auxiliary mud suction pipe, the length of the filter tube is greater than the diameter of the auxiliary mud suction pipe, the inner cavity of the filter tube is hollow and the top is open, the inner cavity of the filter tube is connected to the inner cavity of the auxiliary mud suction pipe, a filter net is placed in the filter tube, and the top opening part of the filter tube is provided with a sealing cover threadedly connected to the filter tube.

[0015] Through the above technical solution, when the industrial sludge enters the auxiliary sludge suction pipe, it moves toward the filter pipe and is filtered by the filter screen. The filtered industrial sludge enters the main sludge suction pipe, and impurities are filtered by the filter screen.

[0016] Preferably, the cross section of the filter screen is annular, and the size of the filter screen is adapted to the size of the filter tube.

[0017] Through the above technical solution, by setting a filter screen with a size that matches the filter tube, the filter screen is directly placed in the filter tube. The filter screen contacts the inner wall of the filter tube due to its own elastic force, so as to filter impurities and facilitate the disassembly and assembly of the filter screen.

[0018] Preferably, an annular pressing block adapted to the filter screen is integrally formed on the side of the sealing cover facing the filter tube, and the annular pressing block extends into the filter tube and contacts the end of the filter screen.

[0019] Through the above technical solution, when the sealing cover is fixedly connected to the filter tube, the annular pressure block contacts and presses the filter screen, preventing the filter screen from shaking up and down during operation and affecting the filtering efficiency, thereby improving the efficiency of the device in filtering impurities.

[0020] Preferably, a plurality of evenly arranged fixed tubes are radially provided on the main mud suction pipe, each of the fixed tubes is located between every two adjacent auxiliary mud suction pipes, the inner cavity of the fixed tube is hollow and is connected to the main mud suction pipe, one end of the fixed tube is open away from the main mud suction pipe, and the connecting tube extends toward one end of the fixed tube into the fixed tube and is threadedly connected to the fixed tube.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] A sludge suction device capable of filtering impurities for industrial sludge treatment, such as Figure 1-5 As shown, it includes a sludge suction pump and a main sludge suction pipe 2 located in a sedimentation tank. The discharge port of the sludge suction pump is connected to the water inlet of the sludge collection tank through a pipeline, and the water inlet of the sludge suction pump is connected to the main sludge suction pipe 2 located in the sedimentation tank through a connecting pipe 1. The inner cavity of the main sludge suction pipe 2 is hollow and closed at both ends. The main sludge suction pipe 2 is radially provided with a plurality of evenly arranged auxiliary sludge suction pipes 3. The inner cavity of the auxiliary sludge suction pipe 3 is hollow and connected to the main sludge suction pipe 2. The auxiliary sludge suction pipe 3 is open at one end away from the main sludge suction pipe 2, and a blocking component for cutting and filtering the condensed sludge is provided at the opening of the auxiliary sludge suction pipe 3.

[0034] like Figure 1 and Figure 2The sludge suction pump provides power so that the industrial sludge in the sedimentation tank enters the auxiliary sludge suction pipe 3, the main sludge suction pipe 2 and the connecting pipe 1 in turn to be collected. When the industrial sludge or large particles of impurities enter the auxiliary sludge suction pipe 3, the large particles of impurities are blocked by the blocking component, and the condensed industrial sludge is also cut, so that the condensed industrial sludge is dispersed, reducing the possibility of large particles of impurities and condensed industrial sludge blocking the main sludge suction pipe 2, the auxiliary sludge suction pipe 3 and the connecting pipe 1, and also reducing the possibility of condensed industrial sludge being unable to be discharged, thereby improving the working efficiency of the device without affecting the use of the device.

[0035] like Figure 1 and Figure 2 The blocking component includes a connecting cover 4 which is sleeved on the open end of the auxiliary mud suction pipe 3 and threadedly connected to the auxiliary mud suction pipe 3. A plurality of circular grooves 5 are provided on the connecting cover 4. A cutting tube 6 which is adapted to the circular groove 5 is integrally formed in each circular groove 5. The inner cavity of the cutting tube 6 is hollow and open at both ends. The end of the cutting tube 6 away from the auxiliary mud suction pipe 3 is a knife edge. When the condensed sludge contacts the connecting cover 4 and enters the auxiliary mud suction pipe 3, the condensed industrial sludge is cut by the cutting tube 6, so that the condensed industrial sludge is dispersed to facilitate the discharge of the condensed sludge and prevent the condensed sludge from clogging the auxiliary mud suction pipe 3.

[0036] like Figure 1 and Figure 2 and Figure 3 and Figure 4 In order to improve the cutting strength of the cutting pipe 6, the cutting pipe 6 is tilted, and the inclination angle of the cutting pipe 6 is 30-45 degrees. The end of the cutting pipe 6 away from the auxiliary sludge suction pipe 3 is tilted, and the distance between point A of the cutting pipe 6 and the connecting cover 4 is greater than the distance between point B of the cutting pipe 6 and the connecting cover 4. At the same time, the cutting edge of the cutting pipe 6 is strengthened, which improves the efficiency of the cutting pipe 6 in cutting condensed industrial sludge and improves the strength and service life of the device.

[0037] like Figure 1 and Figure 2 In order to filter small particles of impurities, a filtering component is provided on the auxiliary mud suction pipe 3 to further filter the impurities, further reducing the possibility of the main mud suction pipe 2 being blocked.

[0038] like Figure 1 and Figure 2 The filter assembly includes a filter tube 7 integrally formed with the auxiliary mud suction pipe 3, the center line of the filter tube 7 is perpendicular to the center line of the auxiliary mud suction pipe 3, the length of the filter tube 7 is greater than the diameter of the auxiliary mud suction pipe 3, the inner cavity of the filter tube 7 is hollow and the top is open, the inner cavity of the filter tube 7 is connected with the inner cavity of the auxiliary mud suction pipe 3, a filter net 8 is placed in the filter tube 7, and the top opening part of the filter tube 7 is provided with a sealing cover 9 threadedly connected to the filter tube 7.

[0039] like Figure 1 and Figure 2 When the industrial sludge enters the auxiliary sludge suction pipe 3, it moves toward the direction of the filter pipe 7 and is filtered by the filter screen. The filtered industrial sludge enters the main sludge suction pipe 2, and the impurities are filtered by the filter screen. Since the length of the filter pipe 7 is greater than the diameter of the auxiliary sludge suction pipe 3 and the length of the filter screen is greater than the diameter of the auxiliary sludge suction pipe 3, the filter screen will not enter the auxiliary sludge suction pipe 3 from the filter pipe 7.

[0040] like Figure 1 and Figure 2 The filter screen has a ring-shaped cross section, and its size is matched with the size of the filter tube 7. By setting a filter screen whose size is matched with the filter tube 7, the filter screen is directly placed in the filter tube 7. The filter screen contacts the inner wall of the filter tube 7 due to its own elastic force, so as to filter impurities and facilitate the disassembly and assembly of the filter screen.

[0041] like Figure 1 and Figure 2 and Figure 5 The sealing cover 9 is integrally formed with an annular pressing block 10 adapted to the filter screen on one side facing the filter tube 7. The annular pressing block 10 extends into the filter tube 7 and contacts the end of the filter screen. When the sealing cover 9 is fixedly connected to the filter tube 7, the annular pressing block 10 contacts and presses the filter screen to prevent the filter screen from shaking up and down during operation and affecting the filtering efficiency, thereby improving the efficiency of the device in filtering impurities.

[0042] like Figure 1 and Figure 2 A plurality of evenly arranged fixed pipes 11 are radially provided on the main mud suction pipe 2, and each fixed pipe 11 is respectively located between every two adjacent auxiliary mud suction pipes 3. The inner cavity of the fixed pipe 11 is hollow and connected with the main mud suction pipe 2. The fixed pipe 11 is open at one end away from the main mud suction pipe 2. The connecting pipe 1 extends into the fixed pipe 11 toward one end of the fixed pipe 11 and is threadedly connected with the fixed pipe 11. The fixed pipe 11 is located between every two adjacent auxiliary mud suction pipes 3 to facilitate uniform sludge discharge. The connecting pipe 1 and the fixed pipe 11 are threadedly connected, which makes it convenient to replace the main mud suction pipe 2 and reduces the replacement cost of the device.

[0043] When in use, the drain outlet of the sludge suction pump is connected to the water inlet of the sludge collection tank through a pipeline, and the water inlet of the sludge suction pump is connected to the main sludge suction pipe 2 through a connecting pipe 1. The main sludge suction pipe 2 and the auxiliary sludge suction pipe 3 are an integrated structure and are placed at the bottom of the sedimentation tank;

[0044] The industrial sludge precipitated in the sedimentation tank is powered by the sludge suction pump and moves toward the auxiliary sludge suction pipe 3. When the industrial sludge, large impurities, small impurities and condensed industrial sludge enter the connection cover 4 and contact the cutting pipe 6, the industrial sludge and small impurities can directly enter the auxiliary sludge suction pipe 3, the large impurities are blocked by the cutting pipe 6, and the condensed industrial sludge is cut and dispersed by the cutting pipe 6 and then enters the auxiliary sludge suction pipe 3.

[0045] The industrial sludge and small particles of impurities entering the auxiliary sludge suction pipe 3 move toward the main sludge suction pipe 2, and are filtered by the filter screen 8 when passing through the filter screen. The industrial sludge passes through the filter screen 8 and enters the main sludge suction pipe 2, and the small particles of impurities are blocked by the filter screen and cannot enter the main sludge suction pipe 2. The industrial sludge entering the main sludge suction pipe 2 enters the connecting pipe 1 through the fixed pipe 11, and then enters the water storage tank, and is discharged by the sludge suction pump;

[0046] After the device has been used for a period of time, the staff empties the sedimentation tank, threads the connecting cover 4 and the auxiliary mud suction pipe 3, removes the connecting cover 4 by threads, inspects and replaces the cutting pipe 6 on the connecting cover 4, and cleans the small particles of impurities accumulated between the filter screen and the connecting cover 4. The sealing cover 9 is opened, the filter screen is pulled out, and the filter screen is cleaned and replaced. Then the fixed pipe 11 and the connecting pipe 1 are disconnected, and the main mud suction pipe 2 is cleaned and replaced. The device has low cost and is easy to disassemble and assemble.
