Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, and in particular to a sludge solidification treatment device and method. Background Technology

[0002] With the continuous development of modern society and economy, the scale of engineering construction is expanding day by day, resulting in the generation of a large amount of waste such as silt. Especially in the process of dredging and clearing rivers and lakes and various engineering constructions, the problem of silt treatment is becoming increasingly prominent. This silt has a high water content and low strength, and cannot be used directly as engineering soil. Therefore, it is necessary to solidify the silt for subsequent use, turning waste into treasure and realizing the recycling of resources.

[0003] Chinese patent CN117700060A discloses a sludge solidification treatment machine and solidification process, including: a mixing arm, the top of which is connected to an excavator arm via a connector, and mixing heads are fixed on both sides of its bottom; blades; a distributing disc, on which the distributing disc is coaxially fixedly installed on the mixing head, and the distributing disc is connected to a solidifying agent tank via a main supply pipe; and a scraper assembly. Although the above patent can spray the solidifying agent into the agitated sludge for solidification, and scrape the sludge from the nozzle to prevent blockage, since the nozzle is inside the sludge when spraying the solidifying agent, the scraper cannot scrape off the sludge adhering to the inner wall of the nozzle. Some sludge will directly enter and adhere to the inner wall of the nozzle, causing blockage and affecting the spraying of the solidifying agent. As a result, the solidifying agent cannot be sprayed out smoothly to solidify the sludge, affecting the efficiency of sludge solidification. Summary of the Invention

[0004] The present invention aims to solve the problems existing in the above-mentioned patents. To this end, a sludge solidification treatment device and method are proposed that can scrape off and discharge the sludge adhering to the inner wall of the nozzle of the discharge pipe to prevent blockage and affect the spraying of the curing agent, thereby improving the sludge solidification efficiency.

[0005] To overcome the shortcomings of the sludge solidification process, where the scraper cannot remove the sludge adhering to the inner wall of the nozzle when the hardener is sprayed from inside the sludge, causing some sludge to directly enter and adhere to the inner wall of the nozzle, resulting in blockage and affecting the spraying of the hardener, thus hindering the smooth spraying of the hardener to solidify the sludge and reducing the efficiency of sludge solidification, this invention provides a sludge solidification treatment device and method that can scrape and discharge the sludge adhering to the inner wall of the nozzle of the discharge pipe to prevent blockage and affect the spraying of the hardener, thereby improving the efficiency of sludge solidification.

[0006] This invention is achieved through the following technical solution: a sludge solidification treatment device, comprising a shell and a fixed base fixedly connected to the shell, with fixed shells fixedly connected between the two sides of the fixed base and the outer side of the shell, a three-way pipe fixedly connected to the fixed base, the tail end of the three-way pipe fixedly passing through the fixed shell, an expansion joint installed at the tail end of the three-way pipe, a discharge pipe connected to the expansion joint, and the nozzle of the discharge pipe penetrating the fixed shell, further comprising a stirring component, a mounting shell, a rotating ring, a spiral scraper, a rotating rod, a hard brush, and a material control component, wherein the stirring component is mounted on the shell for stirring the sludge, and the fixed shell is fixedly connected to the shell. A rotating ring is rotatably connected to the upper part of the discharge pipe. The end of the rotating ring is rotatably connected to the tail end of the discharge pipe. A spiral scraper is fixedly connected to the inner side of the rotating ring, which is in contact with the inner wall of the discharge pipe. A rotating rod is rotatably connected between the housing and the fixed housing. The rotating rod is connected to the outer side of the rotating ring by a synchronous belt assembly. A hard brush located outside the housing is fixedly fitted at the end of the rotating rod. The rotating rod is used to drive the rotating ring to rotate, and the rotating ring drives the spiral scraper to rotate, so that the spiral scraper scrapes off the sludge attached to the inner wall of the nozzle of the discharge pipe and discharges it. The material control component is installed between the housing and the discharge pipe to control the curing agent in the discharge pipe.

[0007] Further explanation: the agitation assembly includes a spiral stirring shaft that rotates symmetrically through the housing. The spiral stirring shaft is inclined to agitate the sludge. An electric rotating shaft is vertically mounted on the fixed base, and a bevel gear assembly is connected between the electric rotating shaft and the end of the spiral stirring shaft.

[0008] Further explanation: The material control assembly includes a ball valve rotatably connected to the discharge pipe. A grooved wheel is fixedly mounted on the shaft of the ball valve. A support plate located inside the fixed housing is symmetrically fixed to the housing. A guide shaft is rotatably connected to the support plate. A guide disc that contacts the outer side of the grooved wheel is fixedly mounted on the guide shaft. A contact rod located in the groove of the grooved wheel is fixedly connected to the eccentric position of the guide disc to drive the grooved wheel to rotate. An intermittent rotation assembly is provided between the guide shaft and the housing to drive the guide shaft to rotate intermittently.

[0009] Further explanation: The intermittent rotation component includes a guide bevel gear fixedly mounted on the end of the guide shaft, a vertical rod symmetrically rotatably connected to the housing and located inside the fixed housing, the vertical rod and the electric rotating shaft are driven by a synchronous belt assembly, the top of the vertical rod and the end of the rotating rod are connected by a bevel gear drive, and a missing gear that meshes with the guide bevel gear is fixedly mounted on the vertical rod.

[0010] Further explanation: the sludge solidification treatment device also includes a striking component, which includes a cross bar fixedly mounted on a rotating rod. The cross bar corresponds to the discharge pipe, and striking rods are rotatably connected to all four ends of the cross bar for striking and vibrating the discharge pipe. A torsion spring connects the striking rods to the cross bar.

[0011] Further explanation: the sludge solidification treatment device also includes brush plates rotatably connected to both sides of the outer shell, used to remove residual sludge from the spiral mixing shaft; a tie rod is fixed to the top of the brush plates.

[0012] To further explain, the sludge solidification treatment device also includes an agitator fixed to the bottom of the electric rotating shaft for agitating the sludge.

[0013] A sludge solidification treatment method using a sludge solidification treatment device includes the following steps:

[0014] S1. Installation: Connect the mounting bracket to the excavator boom and connect the feed end of the tee pipe to the container containing the curing agent.

[0015] S2. Start-up: The electric rotating shaft drives the spiral stirring shaft to rotate via the bevel gear assembly. The electric rotating shaft also drives the vertical rod to rotate via the synchronous belt assembly, which causes the ball valve to rotate intermittently to open and close. It also causes the spiral scraper to rotate, and then discharges the curing agent into the three-way pipe. The curing agent in the three-way pipe is discharged into the expansion joint. When the ball valve is opened, the curing agent is discharged into the discharge pipe, and the discharge pipe sprays out the curing agent.

[0016] S3. Solidification treatment: When the spiral mixing shaft moves and comes into contact with the sludge, the spiral mixing shaft stirs the sludge and solidifies it with a solidifying agent. At the same time, the rotating spiral scraper can scrape off the sludge attached to the inner wall of the discharge pipe nozzle and discharge it.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. First, operate the excavator to move the boom. The boom, through the housing, drives the spiral mixing shaft to move and contact the sludge. Start the electric rotating shaft. The spiral mixing shaft rotates to agitate the sludge, and the discharge pipe can intermittently discharge the curing agent. The discharged curing agent comes into contact with the sludge, and the agitating spiral shaft solidifies the sludge through the curing agent. At the same time, the rotating ring drives the spiral mixing shaft to rotate. The rotation of the spiral mixing shaft scrapes off the sludge adhering to the inner wall of the discharge pipe nozzle and discharges it to prevent the sludge from adhering to the inner wall of the discharge pipe nozzle and causing blockage, which would affect the spraying of the curing agent, thereby improving the efficiency of sludge solidification.

[0019] 2. Under the action of the drive rod and the grooved wheel, the ball valve can be rotated 90 degrees intermittently. Whenever the ball valve is closed, it blocks the curing agent, which allows the curing agent in the expansion joint to continuously increase. When the ball valve is opened and does not block the curing agent, the curing agent is violently sprayed out under the action of the expansion joint to solidify the sludge. In this way, the violent spraying of the curing agent can improve the discharge efficiency, thereby improving the curing efficiency.

[0020] 3. Under the action of the striking rod, whenever the spiral scraper rotates to remove the sludge attached to the inner wall of the discharge pipe nozzle, the rotation of the striking rod can knock and vibrate the discharge pipe. The vibration of the discharge pipe vibrates the attached sludge, which can make the sludge attached to the inner wall of the discharge pipe nozzle better scraped off, thereby improving the sludge removal effect.

Detailed Implementation

[0032] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, and lateral, also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0033] Example: A sludge solidification treatment device, please refer to [link / reference]. Figures 1-6 As shown, the device includes a housing 1 and a fixed base 3 that is fixedly inserted into the middle of the top of the housing 1. The lower left and right sides of the fixed base 3 are respectively fixed to the left and right sides of the top of the housing 1. A three-way pipe 5 is fixedly inserted into the fixed base 3, with its two ends fixedly inserted into the top of the left and right fixed shells 4. Expansion joints 6 are installed at both ends of the three-way pipe 5, and discharge pipes 7 are connected to the expansion joints 6. The nozzles of the discharge pipes 7 penetrate the fixed shells 4. The device also includes a stirring assembly, a mounting shell 9, a rotating ring 10, a spiral scraper 101, a rotating rod 11, a hard brush 12, and a material control assembly. The stirring assembly is installed on the housing 1. When the stirring assembly operates, it can agitate the sludge, allowing the sludge to fully contact the solidifying agent for solidification. The housing 1 is fixed to the side of the left and right fixed shells 4 that is furthest from each other. Rotating rings 1 are rotatably inserted into both left and right housings 1. The ends of the left and right rotating rings 10 that are close to each other are rotatably connected to the tail ends of the left and right discharge pipes 7. Spiral scrapers 101 are fixedly connected to the inner side of the left and right rotating rings 10, and the spiral scrapers 101 are in contact with the inner wall of the discharge pipe 7. Rotating rods 11 are rotatably connected between the left and right housings 1 and the left and right fixed housings 4, respectively. The rotating rods 11 are connected to the outer side of the rotating rings 10 through a synchronous belt assembly. Hard brushes 12 are fixedly fitted at the ends of the left and right rotating rods 11 that are far apart from each other. The hard brushes 12 are located outside the housings 1. The rotating rods 11 are used to drive the rotating rings 10 to rotate, and the rotating rings 10 drive the spiral scrapers 101 to rotate, so that the spiral scrapers 101 scrape off and discharge the sludge attached to the inner wall of the nozzle of the discharge pipe 7. The material control component is installed between the housings 1 and the discharge pipe 7. When the material control component is in operation, the material control component can control the curing agent in the discharge pipe 7.

[0034] Please see Figure 2 As shown, the agitation assembly includes a bevel gear assembly 8, an electric rotating shaft 81, and a spiral stirring shaft 82. The spiral stirring shaft 82 is symmetrically rotated on the housing 1. The spiral stirring shaft 82 is inclined. When the spiral stirring shaft 82 rotates, it can agitate the sludge. The electric rotating shaft 81 is vertically installed in the middle of the fixed base 3. The bevel gear assembly 8 is connected between the lower part of the electric rotating shaft 81 and the inner ends of the spiral stirring shafts 82 on the left and right sides.

[0035] Please see Figure 5 and Figure 6 As shown, the material control assembly includes a ball valve 13, an intermittent rotation assembly, a support plate 132, a guide shaft 133, a guide disc 134, a contact rod 135, and a grooved wheel 136. A ball valve 13 is rotatably connected to the discharge pipe 7. A grooved wheel 136 is fixedly fitted onto the front side of the shaft of the ball valve 13. Support plates 132 are symmetrically fixed to the top of the outer shell 1. The left and right support plates 132 are located inside the left and right fixed shells 4, respectively. A guide shaft 133 is rotatably connected to the upper part of the support plate 132. A guide disc 134 is fixedly fitted onto the guide shaft 133. The guide disc 134 contacts the outer side of the grooved wheel 136. A contact rod 135 is fixedly fixed to the eccentric position on the front side of the guide disc 134. The contact rod 135 is located in the groove of the grooved wheel 136. When the contact rod 135 rotates, it can drive the grooved wheel 136. 6. Rotation: An intermittent rotation assembly is provided between the guide shaft 133 and the housing 1. When the intermittent rotation assembly is in operation, it can drive the guide shaft 133 to rotate intermittently. The intermittent rotation assembly includes a vertical rod 131, a missing gear 1311, and a guide bevel gear 1312. The guide bevel gear 1312 is fixedly mounted on the front end of the guide shaft 133 on both the left and right sides. The vertical rod 131 is symmetrically rotatably connected to the top of the housing 1. The vertical rod 131 is located inside the fixed housing 4. The vertical rod 131 on both the left and right sides is driven by the electric rotating shaft 81 through a synchronous belt assembly. The top ends of the vertical rod 131 on both the left and right sides are respectively connected to the inner ends of the rotating rods 11 on both the left and right sides through bevel gear transmission. The missing gear 1311 is fixedly mounted on the upper part of the vertical rod 131. The missing gear 1311 meshes with the guide bevel gear 1312.

[0036] First, install the mounting base 3 on the excavator's boom connection, and connect the T-connector 5 to the container for discharging the curing agent. Then, start the electric shaft 81 to rotate. The electric shaft 81 drives the left and right spiral mixing shafts 82 to rotate via the bevel gear assembly 8. Simultaneously, the rotation of the electric shaft 81 drives the vertical rod 131 to rotate via the synchronous belt assembly. The rotation of the vertical rod 131 drives the missing gear 1311 to rotate. The missing gear 1311 meshes with the guide bevel gear 1312, which in turn drives the guide bevel gear 1312 to rotate. The guide bevel gear 1312 drives the guide shaft 133 to rotate, which in turn drives the guide disc 134 to rotate. The rotation of the guide disc 134 drives the contact rod 135 to rotate, which in turn drives the grooved wheel 136 to rotate 90 degrees. The grooved wheel 136 drives the ball valve 13 to rotate 90 degrees and open. The missing gear 1311 continues to rotate and disengages from the guide bevel gear 1312. The guide bevel gear 1312 stops driving the guide disc 134 to rotate, and the guide disc 134 stops driving the contact rod 135 to rotate. When the missing gear 1311 rotates and engages with the guide bevel gear 1312 again, the missing gear 1311 drives the guide bevel gear 1312 to rotate once. The guide bevel gear 1312 drives the guide disc 134 to rotate through the guide shaft 133. The guide disc 134 drives the contact rod 135 to rotate. At this time, the contact rod 135 rotates and disengages from the grooved wheel 136. The grooved wheel 136 will not drive the ball valve 13 to rotate. This process repeats. When the contact rod 135 rotates for the fourth time, the contact rod 135 drives the ball valve 135 to rotate again. The grooved wheel 136 rotates, causing the ball valve 13 to rotate 90 degrees to close. This allows the ball valve 13 to rotate intermittently for opening and closing. Simultaneously, the rotation of the vertical rod 131, via a bevel gear transmission, drives the rotating rod 11 to rotate. The rotating rod 11 drives the hard brush 12 to rotate, and the hard brush 12 rotates and contacts the rotating ring 10. The rotating rod 11 also drives the rotating ring 10 to rotate via a synchronous belt assembly. The rotating ring 10 then drives the spiral scraper 101 to rotate. Subsequently, the excavator is started, moving the boom. The boom movement moves the fixed base 3, which, through the housing 1, drives the spiral mixing shaft 82 to rotate, causing the spiral mixing shaft 82 to move into the sludge. The rotating spiral mixing shaft 82 stirs the sludge and simultaneously discharges the solidifying agent into the three-way pipe 5. The curing agent in pipe 5 flows into expansion joint 6. When ball valve 13 is closed, the curing agent in expansion joint 6 is blocked from spraying out, causing the curing agent in expansion joint 6 to continuously increase. When ball valve 13 opens, due to the action of expansion joint 6, the expansion structure violently discharges the curing agent into discharge pipe 7. Discharge pipe 7 violently sprays out the curing agent, which comes into contact with the sludge being stirred. This violent spraying of the curing agent improves discharge efficiency, thereby increasing curing efficiency. The spiral stirring shaft 82 then mixes the sludge and curing agent together. Under the action of the curing agent, the sludge is cured. When ball valve 13 closes again, the curing agent stops flowing into discharge pipe 7, and the curing agent in expansion joint 6 continues to increase. This process repeats.The intermittent, forceful spraying of the curing agent completes the curing of the sludge. During the curing process, some sludge will enter and adhere to the inner wall of the nozzle of the discharge pipe 7. The spiral scraper 101 can scrape off the sludge adhering to the inner wall of the nozzle of the discharge pipe 7 to prevent sludge from adhering to the inner wall of the nozzle of the discharge pipe 7 and causing blockage, thus affecting the spraying of the curing agent, thereby improving the efficiency of sludge curing. The scraped sludge is pushed out by the spiral scraper 101 and discharged through the rotating ring 10. At the same time, the rotation of the stiff brush 12 can remove the sludge remaining on the rotating ring 10 to prevent sludge remaining on the rotating ring 10 from affecting the discharge of the curing agent, thus ensuring the smooth discharge of the curing agent, and the excavator can then be driven. The movement of the spiral mixing shaft 82 causes it to solidify all the sludge using a curing agent. Once the sludge is completely solidified, the flow of curing agent into the three-way pipe 5 is stopped, and the discharge pipe 7 stops discharging the curing agent. The excavator is then operated to move the housing 1 via the boom, causing the housing 1 to move the spiral mixing shaft 82 and disengage it from the solidified sludge. The electric rotating shaft 81 is then shut off, stopping its rotation of the spiral mixing shaft 82 via the bevel gear assembly 8. The electric rotating shaft 81 also stops rotating the vertical rod 131, the ball valve 13 stops intermittently rotating, and the spiral scraper 101 stops rotating. The three-way pipe 5 is then separated from the container containing the curing agent, and the mounting base 3 is removed from the excavator's boom.

[0037] Please see Figure 7 and Figure 8 As shown, the sludge solidification treatment device also includes a striking assembly installed on the rotating rod 11. The striking assembly includes a cross rod 14, a striking rod 141, and a torsion spring 142. The cross rod 14 is fixedly mounted on both the left and right rotating rods 11. The cross rod 14 corresponds to the discharge pipe 7. The four ends of the cross rod 14 are rotatably connected to the striking rod 141. When the striking rod 141 rotates and contacts the discharge pipe 7, the striking rod 141 can knock and vibrate the discharge pipe 7. The torsion spring 142 is connected between the striking rod 141 and the cross rod 14.

[0038] When the electric rotating shaft 81 starts to rotate, the rotating rod 11 rotates, driving the cross rod 14 to rotate. The cross rod 14 drives the striking rod 141 to rotate. When the striking rod 141 rotates and contacts the discharge pipe 7, the striking rod 141 strikes and vibrates the discharge pipe 7. The discharge pipe 7 then vibrates the sludge attached to the inner wall of the nozzle. The rotating spiral scraper 101 scrapes away and discharges the vibrating sludge. As the striking rod 141 continues to rotate, the discharge pipe 7 pushes the striking rod 141 to swing, and the torsion spring 142 is compressed. When the striking rod 141 continues to rotate and disengages from the discharge pipe 7, the striking rod 141 swings back to its original position due to the action of the torsion spring 142. This process is repeated, so that the striking rod 141 continuously strikes and vibrates the discharge pipe 7, causing the sludge attached to the inner wall of the nozzle of the discharge pipe 7 to be continuously vibrated and scraped away. When the electric rotating shaft 81 is closed, the rotating rod 11 stops driving the cross rod 14 to rotate, the cross rod 14 stops driving the striking rod 141 to rotate, and the striking rod 141 stops striking and vibrating the discharge pipe 7. This allows the sludge adhering to the inner wall of the nozzle of the discharge pipe 7 to be scraped off more effectively, thereby improving the sludge removal efficiency.

[0039] Please see Figure 9 As shown, the sludge solidification treatment device also includes a brush plate 15 and a pull rod 16. The brush plate 15 is rotatably connected to both the front and rear sides of the housing 1. When the brush plate 15 swings and contacts the spiral stirring shaft 82, the brush plate 15 can remove the sludge remaining on the spiral stirring shaft 82. The pull rod 16 is fixedly connected to the top of the brush plate 15 on both the front and rear sides.

[0040] Please see Figure 10 As shown, the sludge solidification treatment device also includes an agitator 17. The agitator 17 is fixedly connected to the bottom end of the electric rotating shaft 81. When the agitator 17 rotates, it can agitate the sludge.

[0041] When the spiral mixing shaft 82 moves and loses contact with the sludge, connect the three-way pipe 5 to a water source and drain water into it. This causes the discharge pipe 7 to intermittently spray water onto the spiral mixing shaft 82, washing away the sludge adhering to it. At this time, pull the lever 16 to swing the brush plate 15 180 degrees, bringing it into contact with the spiral mixing shaft 82. The brush plate 15 then uses water to clean the sludge from the spiral mixing shaft 82. Once the sludge on the spiral mixing shaft 82 is completely removed, stop draining water into the three-way pipe 5 and the discharge pipe 7 stops discharging water. Separate the three-way pipe 5 from the water source and pull the lever 16 to swing the brush plate 15 180 degrees in the opposite direction to reset it. This prevents a large amount of sludge from adhering to the spiral mixing shaft 82, which could affect subsequent use and ensure the effectiveness of the spiral mixing shaft 82.

[0042] When the electric rotating shaft 81 is started, it drives the agitator 17 to rotate. The rotation of the agitator 17 agitates the sludge, mixing it with the solidifying agent and thus completing the solidification process. When the electric rotating shaft 81 is turned off, it stops driving the agitator 17 to rotate. This further agitates the sludge to complete the solidification process, thereby improving the mixing effect.

[0043] A sludge solidification treatment method using a sludge solidification treatment device includes the following steps:

[0044] S1. Installation: Connect the mounting base 3 to the excavator boom and connect the feed end of the tee pipe 5 to the container containing the curing agent.

[0045] S2. Start-up: The electric rotating shaft 81 drives the spiral stirring shaft 82 to rotate via the bevel gear assembly 8. The electric rotating shaft 81 also drives the vertical rod 131 to rotate via the synchronous belt assembly, which causes the ball valve 13 to rotate intermittently to open and close. It also causes the spiral scraper 101 to rotate, and then discharges the curing agent into the three-way pipe 5. The curing agent in the three-way pipe 5 is discharged into the expansion joint 6. When the ball valve 13 is opened, the curing agent is discharged into the discharge pipe 7, and the discharge pipe 7 sprays out the curing agent.

[0046] S3. Curing treatment: When the spiral stirring shaft 82 moves and comes into contact with the sludge, the spiral stirring shaft 82 stirs the sludge and cures the sludge with a curing agent. At the same time, the spiral scraper 101 rotates to scrape off and discharge the sludge attached to the inner wall of the nozzle of the discharge pipe 7.

5. The solidification treatment method of the sludge solidification treatment device as described in claim 4, characterized in that, Includes the following steps: S1. Installation: Connect the mounting bracket (3) to the excavator boom and connect the feed end of the tee pipe (5) to the container containing the curing agent. S2. Start-up: The start-up electric shaft (81) drives the spiral stirring shaft (82) to rotate via the bevel gear assembly (8). The electric shaft (81) also drives the vertical rod (131) to rotate via the synchronous belt assembly. The rotation of the vertical rod (131) drives the guide shaft (133) to rotate intermittently through the meshing of the missing gear (1311) and the guide bevel gear (1312). This causes the guide disc (134) to drive the contact rod (135) to rotate intermittently, which in turn drives the grooved wheel (136) to rotate intermittently by ninety degrees. This causes the ball valve (13) to rotate intermittently to open and close. The rotation of the vertical rod (131) also drives the rotating rod (11) to rotate through the bevel gear transmission. The rotating rod (11) drives the rotating ring (10) to rotate through the synchronous belt assembly. The rotation of the rotating ring (10) drives the spiral scraper (101) to rotate, and then discharges the curing agent into the three-way pipe (5). The curing agent in the three-way pipe (5) is discharged into the expansion joint (6). When the ball valve (13) is opened, the curing agent is discharged into the discharge pipe (7), and the discharge pipe (7) sprays out the curing agent. S3. Solidification treatment: When the spiral stirring shaft (82) moves and comes into contact with the sludge, the spiral stirring shaft (82) stirs the sludge and solidifies the sludge with a solidifying agent. At the same time, the spiral scraper (101) rotates to scrape off and discharge the sludge attached to the inner wall of the nozzle of the discharge pipe (7).
