Description

Technical Field

[0001] The invention belongs to the technical field of material transportation, and in particular relates to a quantitative loading and conveying device for solidified soil packaging. Background Art

[0002] Solidified soil: It is an engineering material that adds a solidifying agent to the soil and then undergoes a series of chemical or physical reactions to make the originally loose soil have a certain strength, stability and durability. It can be various types of natural soil, such as clay, sand or silt. The particle size, gradation and mineral composition of different types of soil always affect the transportation and packaging efficiency of the solidified soil.

[0003] Clay particles are small and have high surface energy, which makes them highly adhesive. At the same time, clay usually contains a certain amount of water, which further enhances the bonding force between clay particles. Therefore, when conveyed by a screw pump, clay particles will continuously adhere to the inner wall of the screw pump, the surface of the screw, and the port. As time accumulates, the clay will continuously deposit and solidify, which will gradually reduce the effective flow cross-sectional area at the port.

[0004] In addition, there is a certain gap between the screw and the pump casing in the screw pump. When conveying clay, fine particles in the clay continuously enter the aforementioned gap. In this process, the deposition and solidification of clay at the port causes the fluid flow resistance to increase, further resulting in a decrease in the outlet pressure of the screw pump and an increase in the inlet pressure, until the overall conveying stability of the screw pump is affected, that is, pressure loss occurs at the port, and the pressure in the middle part of the pump pipe is insufficient, affecting the smoothness of clay conveying. As the running time increases, clay continues to accumulate in the gap, the friction between the screw and the pump casing increases, the effective flow cross-sectional area at the port gradually decreases, and even the gap between the screw and the bushing is changed, reducing the service life of the seal.

[0036] The method for quantitatively and stably conveying solidified soil adopts the above-mentioned quantitative loading and conveying device for solidified soil packaging to carry out conveying, and the specific steps are as follows:

[0037] S1: First, the pillars are controlled by the bridge slide rails to synchronously drive the rib plate to move until the positions of the filling pipe and the conveying pipe at different positions are interchanged. After that, the rack is controlled by the central shaft gear to drive the mouth ring to move toward or away from each other under the guidance of the filling pipe until the ball is tangent to the electrode ring;

[0038] S2: Then, the telescopic cylinder drives the empty shelf to move into the filling tube under the guidance of the strips, so that the cross bar drives the steel ring to move into the filling tube until the scraper fully covers the inner wall of the filling tube in the axial direction. After that, the cross bar drives the steel ring to rotate. In this process, the engagement between the planetary gear and the gear ring enables the vertical rod to rotate at a speed different from that of the cross bar.

[0039] S3: Finally, through the interaction between the snake mouth groove and the steel ball, the steel ball synchronously controls the matching plate to drive the angle plate to move. After that, the angle shovel, under the joint guidance of the steel ring and the scraper, synchronously follows the angle plate to reciprocate along the axis of the cross bar. At the same time, the cleaning liquid stored in the water tank is gradually guided to the jet pipe through the water guide pipe, so as to cooperate with the scraper to clean the inner wall of the packing tube, thereby improving the cleaning effect and cleaning ability.

[0040] The present invention has the following beneficial effects:

[0041] 1. Under the connecting force of the supporting bridge, the rib plate of the present invention controls the stuffing pipe to synchronously follow the reciprocating motion of the bridge slide rail, so as to realize the alternating docking between the stuffing pipe and the conveying pipe, fully ensure the cleanliness of the stuffing pipe in the state of being connected with the conveying pipe, avoid the shutdown and rectification problem caused by clay deposition on the wall of a single conveying pipe, that is, enhance the stability of the conveying system, balance the pipeline conveying pressure per unit time, reduce the production interruption caused by clay deposition or solidification on the inner wall of the pipeline, help to improve production safety, and at the same time stabilize the effective flow cross-sectional area at the port of the conveying pipe to ensure the transportation and packaging efficiency of clay.

[0042] 2. The present invention realizes that the mouth ring synchronously drives the angle ring to move toward the middle part of the filling tube when the filling tube is replaced by the side rails, so as to release the contact seal between the mouth ring and the feeding tube, and avoid the collision and limitation between the filling tube and the tying ring during the replacement process, which helps to increase the service life of the angle ring, the filling tube and the tying ring; at the same time, through the elastic variable of the telescopic spring itself, the radial or axial runout between the guide rod and the tube sleeve is buffered and degraded, thereby further improving the alignment accuracy between the filling tube and the feeding tube, reducing leakage, and improving the conveying accuracy and efficiency.

[0043] 3. The present invention controls the cross bar to drive the steel ring to move into the filling tube under the joint action of the telescopic cylinder and the rail guide through the empty layer frame, until the scraper completely covers the inner wall of the filling tube. After that, the steel ring is controlled by the cross bar to drive the scraper to rotate. In this process, the meshing action between the planetary gear and the gear ring causes the vertical rod to rotate at a speed different from the steel ring. After that, the snake mouth groove continuously generates mutual movement with the steel ball during the rotation of the vertical rod, so that the angle shovel reciprocates along the axis direction of the cross bar under the joint guidance of the steel ring and the scraper. In this way, while the scraper rotates, the scraper is scraped by the angle shovel, which fully ensures the cleanliness of the scraper and the angle shovel itself, thereby improving the long-term effectiveness of the dredging unit.

[0061] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0062] It should be noted that the terms “vertical”, “horizontal”, “left”, “right” and similar expressions used in this document are only for the purpose of explanation and do not represent the only implementation method.

[0063] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0064] Reference Figure 1 and Figure 3It can be seen that a quantitative loading and conveying device for solidified soil packaging includes a hopper 1, the hopper 1 is a hollow structure, and the hopper 1 is composed of two parts that are snap-fitted together, an assembly unit 2 is arranged on one side of the hopper 1, a transfer unit 3 is arranged inside the hopper 1, and a dredging unit 4 is arranged on the other side of the hopper 1;

[0065] Reference Figure 1 and Figure 2 It can be seen that the assembly unit 2 includes: a table top 21, which is snap-fitted and installed on the end of the distribution hopper 1 away from the water storage tank 11; a chassis 22, which is snap-fitted and installed on the end face of the table top 21 close to the distribution hopper 1; two supports 23, which are symmetrically snap-fitted and installed on the end of the table top 21 away from the chassis 22, and the supports 23 are snap-fitted and installed with the distribution hopper 1; a three-phase motor 24, which is snap-fitted and installed on the end of the chassis 22 away from the supports 23; a coupling 25, which is snap-fitted and installed on the output end of the three-phase motor 24; a three-way valve 26, which is snap-fitted and installed on one end of the end face of the chassis 22 away from the table top 21 through a mounting frame, and the three-way valve 26 is plug-fitted and installed with the coupling 25; a feed pipe 27, which is snap-fitted and installed on the other end of the end face of the chassis 22 away from the table top 21 through a mounting frame, and the feed pipe 27 is snap-fitted and installed with the three-way valve 26.

[0066] The specific working process of assembly unit 2:

[0067] First, the coupling 25 is driven to rotate by the three-phase motor 24, and then the screw (not shown in the figure and not marked, for details, please refer to the screw in the screw pump in the prior art) inside the three-way valve 26 is driven to rotate by the coupling 25. When the screw rotates, a certain vacuum degree is generated inside the pump chamber of the screw pump. Then, the clay is sucked into the pump chamber under the action of the vacuum negative pressure, and after the clay enters the pump chamber, it is gradually filled into the gap between the spiral groove of the screw and the inner wall of the pump chamber;

[0068] Next, the external clay (or other materials that can be used to solidify the soil) enters the interior of the three-way valve 26 through the top valve port. After that, as the screw rotates, the clay is squeezed and sheared in the pump cavity, and gradually moves steadily along the axis direction of the three-way valve 26.

[0069] Finally, the delivery pipe 27 guides the clay in the three-way valve 26 to the inside of the distribution hopper 1. During this process, when the clay reaches the end of the delivery pipe 27, the clay is forced out of the pump cavity due to the rotation of the screw.

[0070] Table 21 and chassis 22: The table 21 provides a stable working environment for the assembly unit 2, the transfer unit 3 and the dredging unit 4, and facilitates the operator to move the equipment as a whole, thereby improving the safety of equipment transfer; the chassis 22 provides height compensation for the corresponding components in the assembly unit 2 (for example, the three-phase motor 24, the three-way valve 26 or the feed pipe 27), thereby facilitating rapid assembly between the assembly unit 2 and the transfer unit 3 or the dredging unit 4, and provides a certain degree of protection for the aforementioned components, thereby enhancing the service life of the aforementioned components.

[0071] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7 It can be seen that the distribution unit 3 includes: a bridge rail 31, which is in one quantity and is installed in the distribution hopper 1 by sliding snap-fitting; two pillars 32, which are symmetrically snap-fitted and installed in the horizontal section of the bridge rail 31; one rib plate 33, which is snap-fitted and installed at one end of the two pillars 32 away from the bridge rail 31; two stuffing tubes 34, which are symmetrically snap-fitted and installed at both ends of the rib plate 33, and both ends of the stuffing tube 34 are chamfered; a cross beam 35, which is snap-fitted and installed in the middle position of the end face of the rib plate 33 away from the pillar 32; a top plate 36, which is snap-fitted and installed in the middle position of the end face of the cross beam 35 away from the rib plate 33, and the cross-sectional shape is convex; a column 37, which is rotatably mounted in the middle position of the end face of the top plate 36 away from the cross beam 35;

[0072] Reference Figure 4 and Figure 6 It can be seen that the end surface of the top plate 36 away from the cross beam 35 is symmetrically mounted with side rails 361 in sliding engagement, and there are two of them. One end of the end surface of the side rail 361 away from the top plate 36 is mounted with a rack 362 that is slidably mounted with the other side rail 361, and the outer wall of the column 37 is mounted with a central shaft gear 363 that meshes with the rack 362. The end surface of the side rail 361 close to the top plate 36 is mounted with a connecting plate 364 at both ends. A mouth ring 365 is mounted on one end of the ring 364 away from the rack 362 and is slidably fitted with the stuffing tube 34. An ear seat 366 is mounted on the end face of the mouth ring 365 away from the rack 362. A sleeve 367 is mounted on one of the two ear seats 366 in the same area of ​​the stuffing tube 34. A guide rod 368 is mounted on the other ear seat 366 and is slidably fitted with the sleeve 367. A telescopic spring 369 is sleeved on the outer wall of the guide rod 368.

[0073] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6It can be seen that the rib plate 33 is symmetrically embedded and slidably mounted on one end of the ring 365, and a spring rod 381 is mounted on one end of the ring 365, and a ball 382 is mounted on one end of the ring 365, and an angle ring 383 is mounted on one end of the ring 365 away from the rack 362, and the diameter of the angle ring 383 is larger than the diameter of the ring 365, and an electrode ring 384 is mounted on the end face of the angle ring 383 near the rack 362, and a tie ring 385 is mounted on the inner wall of one side of the material distribution hopper 1 in a symmetrical shape, and a gear ring 386 is mounted on the inner wall of the tie ring 385;

[0074] The axial depth of the angle ring 383 is greater than the axial depth of the tying ring 385, the length of the discharge pipe 14 entering the inner part of the distribution hopper 1 is less than the axial depth of the tying ring 385, the vertical distance between the end face of the angle ring 383 close to the rack 362 and the end face of the top plate 36 close to the angle ring 383 is greater than the axial depth of the tying ring 385, the vertical distance between the end face of the scraper 413 away from the axis of the cross bar 45 and the axis of the steel ring 46 is equal to the inner wall radius of the filling tube 34, the vertical distance between the end face of the planetary gear 48 away from the cross bar 45 and the axis of the steel ring 46 is less than the inner wall radius of the filling tube 34, in addition, the vertical distance between the bracket 47 and the vertical rod 411 away from the axis of the cross bar 45 and the axis of the steel ring 46 is also less than the inner wall radius of the filling tube 34, and the length of the steel ring 46 and the vertical rod 411 are both greater than the length of the filling tube 34.

[0075] The transposition process of the stuffing tube 34:

[0076] When one of the filling pipes 34 has been in operation for a long time (or when the inner wall of the filling pipe 34 needs to be cleaned after a long operation):

[0077] The pillar 32, under the linkage control of the bridge slide 31, synchronously causes the rib plate 33 to drive the cross beam 35 to move. In specific implementation, the bridge slide 31 can be driven by an electric slider to intermittently reciprocate under the support and guidance of the distribution hopper 1 (the intermittent cycle can be obtained based on the external experiment to obtain the limit operation time of a single filling tube 34 in a harsh environment, as a reference);

[0078] Afterwards, the filling tube 34 is controlled by the rib plate 33 to realize variable position adjustment (i.e., in the initial state, one of the filling tubes 34 is positively engaged with the feed pipe 27 and the discharge pipe 14, and the other filling tube 34 is in an idle state. After the current filling tube 34 has been in operation for a specified time, the positions of the two filling tubes 34 are alternately adjusted through the reciprocating motion of the bridge slide 31, thereby ensuring the effective flow cross-sectional area between the filling tube 34 and the feed pipe 27 and the discharge pipe 14, balancing the pressure, stabilizing the pressure fluctuation, and improving the alignment accuracy between the filling tube 34 and the feed pipe 27 or the discharge pipe 14);

[0079] It is hereby explained that the angle ring 383 does not contact the inner wall of the material distribution hopper 1 in the initial state, that is, the end face of the angle ring 383 close to the inner wall of the material distribution hopper 1 is at a certain distance from the discharge pipe 14 or the feeding pipe 27 entering the material distribution hopper 1, so as to avoid collision and position limitation between the filling pipe 34 and the feeding pipe 27 or the discharge pipe 14 when the filling pipe 34 is replaced;

[0080] The specific process of the angle ring 383 from not contacting to contacting with the inner wall of the same dividing hopper 1 is as follows:

[0081] First, the central shaft gear 363 is controlled by the column 37 and the racks 362 on both sides thereof are meshed. In specific implementation, the column 37 can be driven to rotate by an external motor. After that, the side rails 361 on both sides are controlled by the racks 362 to move toward or away from each other (the movement toward or away from each other is determined by the direction of the external motor).

[0082] Next, under the synchronous control of the connecting plate 364, the mouth ring 365 moves along the axial direction of the filling tube 34 away from the middle part of the filling tube 34 (the movement form of the mouth ring 365 is also a reciprocating motion, and here only the movement of the mouth ring 365 toward the inner wall of the distribution hopper 1 is taken as an example), until the angle ring 383 contacts the inner wall of the distribution hopper 1 (in this process, the filling tube 34 provides a stable guide support to the mouth ring 365, which further improves the movement stability of the mouth ring 365, avoids the influence of external vibration on the single movement accuracy of the angle ring 383, and thus ensures the alignment accuracy between the angle ring 383 and the feeding pipe 27 or the discharge pipe 14);

[0083] In addition, the inner diameter of the angle ring 383 is larger than the outer diameter of the portion of the discharge pipe 14 or the feed pipe 27 entering the feed hopper 1, and the axial depth of the angle ring 383 is larger than the length of the portion of the discharge pipe 14 or the feed pipe 27 entering the feed hopper 1. Therefore, when the angle ring 383 contacts the inner wall of the feed hopper 1, the discharge pipe 14 or the feed pipe 27 can be completely sealed, thereby ensuring the stability, continuity and sustainability of clay transportation.

[0084] Finally, by means of the elastic variable of the telescopic spring 369 itself, the radial or axial runout between the guide rod 368 and the tube sleeve 367 is buffered and degraded (the manifestation of the external impact during the single movement of the mouth ring 365 or the angle ring 383 will be expressed through the radial runout or axial runout between the guide rod 368 and the tube sleeve 367), further improving the alignment accuracy between the filling tube 34 and the conveying tube 27, reducing the leakage, and improving the conveying accuracy and efficiency;

[0085] Detection scheme for the deformation or displacement of mouth ring 365 or angle ring 383:

[0086] When the angle ring 383 moves to the middle area of ​​the filling tube 34 driven by the mouth ring 365, when the ball 382 contacts the electrode ring 384 and maintains a certain interaction force, the force value between the electrode ring 384 and the ball 382 is fed back in real time through the external pressure detection and display device, thereby judging whether the deformation variable and displacement variable of the angle ring 383 or the mouth ring 365 exceed the specified range, which helps to improve the assembly accuracy between the angle ring 383 or the mouth ring 365 and the filling tube 34, and further improve the transportation stability of the clay (in specific implementation, the contact signal between the ball 382 and the electrode ring 384 can be connected to the external pressure display device through the electrical connection between the ball 382 and the electrode ring 384 through the external wire, and a corresponding alarm device can be configured to remind the operator to inspect the mouth ring 365 or the angle ring 383);

[0087] The axial depth of the angle ring 383 is greater than the axial depth of the tie ring 385, the length of the discharge pipe 14 entering the inner part of the distribution hopper 1 is less than the axial depth of the tie ring 385, and the vertical distance between the end face of the angle ring 383 close to the rack 362 and the end face of the top plate 36 close to the angle ring 383 is greater than the axial depth of the tie ring 385. The purpose is:

[0088] To avoid the angle ring 383 from being unable to move to the specified position during the retreat process due to insufficient space margin when moving to the middle area of ​​the filling tube 34 driven by the mouth ring 365, that is, when the angle ring 383 and the feed pipe 27 or the discharge pipe 14 enter the distribution hopper 1 and there is still an overlapping part, the angle ring 383 has already contacted the rib plate 33. At this time, when the bridge slide rail 31 moves, the angle ring 383 moves synchronously. In this process, the angle ring 383 will collide and limit with the discharge pipe 14 or the feed pipe 27, and even affect the normal repositioning of the filling tube 34.

[0089] Reference Figure 8 and Fig. 9 It can be seen that the silting unit 4 includes: two corner frames 41, which are symmetrically mounted on the outer wall of the material distribution hopper 1 away from the feeding pipe 27; a rail 42, which is mounted in the middle of the horizontal section of the corner frame 41; a telescopic cylinder 43, which is mounted on the horizontal section of the corner frame 41 away from the end of the material distribution hopper 1; an empty layer frame 44, which is mounted in the horizontal section of the corner frame 41 by sliding and snapping, and the empty layer frame 44 is mounted in the snapping with the movable end of the telescopic cylinder 43;

[0090] The crossbar 45 is mounted in the middle of the empty shelf 44 by snap-fitting; the steel ring 46 is mounted in the outer wall of the crossbar 45 by snap-fitting; there are three brackets 47, which are mounted in the outer wall of the steel ring 46 by snap-fitting, and two brackets 47 are arranged at one end of the steel ring 46 close to the telescopic cylinder 43, and one bracket 47 is arranged at the other end; the planetary gear 48 is mounted in the middle of the two brackets 47 close to one end of the telescopic cylinder 43 by rotating the rotating shaft;

[0091] Reference Figure 8 and Fig. 9 It can be seen that a vertical rod 411 is rotatably mounted between the brackets 47 at both ends, a snake-mouth groove 412 is provided on the outer wall of the vertical rod 411, a scraper 413 is clamped and mounted on the outer wall of the steel ring 46, and the end of the scraper 413 away from the axis of the steel ring 46 is processed with a right-angle chamfer, and an angle shovel 414 is slidably mounted on the outer wall of the scraper 413 and slidably mounted with the steel ring 46, and the number is two, in addition, the vertical distance between the two angle shovels 414 is at least five centimeters, and the two angle shovels 414 are clamped and mounted on one end away from the axis of the steel ring 46 with an angle plate 415, and the end face of the angle plate 415 close to the vertical rod 411 is clamped and mounted with a matching plate 416, and the matching plate 416 is rotatably mounted with a steel ball 417 matching the snake-mouth groove 412 on one end close to the vertical rod 411;

[0092] Reference Figure 1 and Figure 2 It can be known that a water tank 11 is installed on the outer wall of one end of the distribution hopper 1 close to the rack 362 through a mounting seat, a water pipe 12 is installed on the end of the water tank 11 away from the gear ring 386, a jet pipe 13 is installed on the water outlet end of the water pipe 12, a discharge pipe 14 is installed in the middle of the end face of the distribution pipe away from the water pipe 12, and a water outlet pipe 15 is symmetrically installed on the end face of the distribution hopper 1 away from the discharge pipe 14.

[0093] For the cleaning process of the deposited or solidified clay on the inner wall of the filling pipe 34 (filling pipe 34 in an idle state):

[0094] First, the empty shelf 44 is pushed by the telescopic cylinder 43, and under the support and guidance of the rail 42, it moves toward the dividing hopper 1 until the gear ring 386 is positively meshed with the planetary gear 48. After that, the steel ring 46 is driven to rotate by the cross bar 45. During the rotation process, the steel ring 46 continuously controls the meshing movement between the planetary gear 48 and the gear ring 386. In specific implementation, the cross bar 45 can be driven to rotate by the built-in motor, and the built-in motor can be placed in the middle area of ​​the empty shelf 44.

[0095] Next, the scraper 413 is rotated to scrape off the clay deposited or solidified on the inner wall of the filling tube 34 (the purpose of chamfering the working ends of the scraper 413 and the filling tube 34 is to reduce the contact area between the scraper 413 and the inner wall of the filling tube 34, thereby reducing the friction between the two and improving the scraper 413's scraping effect on the clay deposited or solidified on the inner wall of the filling tube 34);

[0096] Finally, when the vertical rod 411 synchronously controlled by the planetary gear 48 rotates, the snake mouth groove 412 continuously moves with the steel ball 417. In this process, the coordination plate 416, under the control of the steel ball 417, synchronously drives the angle plate 415 to move, and then the angle plate 415 controls the angle shovel 414 at a distance to make reciprocating motion along the axis direction of the cross bar 45 under the joint guidance of the scraper 413 and the steel ring 46 (the realization of reciprocating motion can be determined by the steering of the cross bar 45-the steering between the steel ring 46 and the cross bar 45 is synchronized), so that the scraper 413 rotates and the angle shovel 414 is scraped to the scraper 413, fully ensuring the cleanliness of the scraper 413 and the angle shovel 414 itself (reducing the re-deposition rate of clay on the end surface of the scraper 413); thereby improving the long-term effectiveness of the desilting unit 4;

[0097] External components assist the desilting unit 4:

[0098] When the scraper 413 cleans the inner wall of the filling tube 34:

[0099] First, the cleaning liquid stored in the water tank 11 is guided to the jet pipe 13 area through the water guide pipe 12. In specific implementation, the cleaning liquid in the water tank 11 can be guided to the jet pipe 13 area through the water guide pipe 12 through an external pressure pump;

[0100] Next, the cleaning liquid is evenly sprayed to the working area of ​​the scraper 413 through the jet pipe 13, so as to assist the scraper 413 in cleaning the inner wall of the filling tube 34, and further enhance the cleaning effect of the scraper 413 on the clay in the inner wall of the filling tube 34;

[0101] Finally, the sewage in the distribution hopper 1 is guided to the outside through the outlet pipe 15 by an external pressure pump.

[0102] The working principle of the quantitative loading and conveying device for solidified soil packaging provided by the present invention is as follows: Step 1: First, the pillar 32 is controlled by the bridge slide rail 31 to synchronously drive the rib plate 33 to move until the positions of the filling pipe 34 and the conveying pipe 27 at different positions are interchanged, and then the rack 362 is controlled by the central shaft gear 363 to drive the mouth ring 365 to move toward or away from each other under the guidance of the filling pipe 34 until the ball 382 is tangent to the electrode ring 384;

[0103] Step 2: Then, the telescopic cylinder 43 drives the empty layer frame 44 under the guidance of the strip plate, so that the cross bar 45 drives the steel ring 46 to move into the filling tube 34 until the scraper 413 fully covers the inner wall of the filling tube 34 in the axial direction. After that, the cross bar 45 drives the steel ring 46 to rotate. In this process, the planetary gear 48 is meshed with the gear ring 386, so that the vertical rod 411 rotates at a speed different from that of the cross bar 45.

[0104] Step 3: Finally, through the interaction between the snake mouth groove 412 and the steel ball 417, the steel ball 417 synchronously controls the matching plate 416 to drive the angle plate 415 to move. After that, the angle shovel 414, under the joint guidance of the steel ring 46 and the scraper 413, synchronously follows the angle plate 415 to reciprocate along the axis of the cross bar 45. At the same time, the cleaning liquid stored in the water tank 11 is gradually guided to the jet pipe 13 through the water guide pipe 12, so as to cooperate with the scraper 413 to clean the inner wall of the filling tube 34, thereby improving the cleaning effect and cleaning ability.
