Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

In general, the chute tube is installed on a device or a production line at a certain angle, and the installation inclination angle of the chute tube determines the speed of material passing through. The more it is inclined toward the vertical state, the greater its flow rate.

Referring to fig. 1, which shows a perspective view of a chute in the present embodiment, fig. 2 shows a schematic perspective cross-sectional view of the chute; the chute provided by the embodiment comprises a pipe body 10 and an inner lining pipe 20, wherein the inner lining pipe 20 is attached to the inner wall of the pipe body 10, and can enable the materials to pass through the inner lining pipe 20, namely the materials enter the pipe body 10 from a feed inlet 13 and then enter the inner lining pipe 20, and the materials flow out of the inner lining pipe 20 and then flow to other equipment from a discharge outlet 14.

In order to control the flow rate of the material, a blocking portion 21 capable of slowing down the conveying speed of the material is arranged on a part of the circumferential direction of the inner wall of the lining pipe 20, and the material can collide against the blocking portion 21 when flowing through the lining pipe 20, so that the material is decelerated. The "part of the inner wall of the lining pipe 20 in the circumferential direction" described in the present embodiment means a part of the entire circumference of the inner wall of the lining pipe 20, for example: the stopper 21 may occupy one third (i.e., 120 °) of the entire circumference of the inner wall of the inner liner tube 20. The technical field can specifically set the size of the space occupied by the blocking part 21 according to the size of the required flow restriction, for example, the blocking part 21 can be set to occupy a larger circumferential range when a larger flow restriction is required, and the blocking part 21 can be set to occupy a smaller circumferential range when a smaller flow restriction is required.

In order to facilitate the control of the material deceleration, the lining pipe 20 is arranged to be rotatable around the axis of the lining pipe 20 along the circumferential direction of the lining pipe 20. Thereby can make the stopper 21 be located different positions, usually, the swift current material pipe can incline to set up, so the material can flow along the downside in interior bushing pipe 20 under the action of gravity, if this position has stopper 21, then can play the effect of blockking the material, so can make stopper 21 be located downside or upside through rotatory interior bushing pipe 20, or make some of stopper 21 can block the material, thereby can be more nimble realization to a certain extent to the accurate control of material speed, on the other hand, also avoided causing the material to flow speed too slowly in the swift current material pipe because of the effect of blockking of stopper 21 is too big, thereby cause the problem of putty in the swift current material pipe. In addition, by arranging the blocking portion 21 to occupy a different circumferential range, the cushioning effect can be adjusted as desired. For example, when the stopper 21 is provided to occupy a circumferential range smaller than a semicircle, it may have a state of not being buffered at all by the stopper 21; when the stopper 21 is disposed to occupy a circumferential range greater than a semicircle, it may have a maximum buffer state buffered by the entire stopper 21 and a partial buffer state buffered only by a portion of the stopper 21.

The blocking portion 21 may be in any suitable form as long as it can provide deceleration to the material. For example, the blocking portion 21 may include a plurality of blocking plates sequentially arranged along the axial direction of the lining tube 20, preferably, all the blocking plates are equally spaced along the axial direction of the lining tube 20, and the blocking plates are preferably made of a metal material or other materials with good wear resistance. The cross section of the baffle plate can be in a circular shape, a semicircular shape, an oval shape, a triangular shape and the like, and the same functional effect can be realized.

The baffle is arc-shaped or wavy, and when the baffle is arc-shaped, the circular surface where the arc is located is perpendicular to the axial direction of the lining pipe 20, so that the flow of the materials can be limited to the greatest extent. Certainly, the circular surface where the circular arc is located may not be perpendicular to the axial direction of the lining pipe 20, that is, one end of the circular arc is close to the feeding port 13, and the other end is close to the discharging port 14, so that the shape of the formed baffle plate on the inner wall of the lining pipe 20 is similar to a spiral shape, on one hand, the spiral baffle plate can enable the material to flow along the spiral direction, thereby facilitating the sliding of the material, and enabling the material retention amount to be reduced on the baffle plate or even no material retention to be left, on the other hand, the flow path of the material is increased to play a role in slowing down the.

In order to facilitate the rotation of the lining pipe 20, the pipe body 10 and the lining pipe 20 are generally formed in a straight cylindrical shape, and in order to facilitate the connection of the pipe body 10 to other components, the pipe body 10 may include a straight pipe portion and a bent pipe portion which communicate with each other, and at this time, the lining pipe 20 may be disposed in the straight pipe portion to facilitate the rotation of the lining pipe 20.

Preferably, the inner lining tube 20 is formed with an adjusting portion 22 for adjusting the inner lining tube 20 to rotate around the axis of the inner lining tube 20, and the adjusting portion 22 may be a handle or the like, and an operator may rotate the inner lining tube 20 by shaking the handle. The adjusting groove 11 is formed on the tube body 10, the adjusting portion 22 is configured to slide along the adjusting groove 11, that is, the adjusting portion 22 slides along the extending direction of the adjusting groove 11, and the rotation of the lining tube 20 is determined by the extending length of the adjusting groove 11.

Further, referring to fig. 3 to 6, the adjustment groove 11 extends along the circumferential direction of the pipe body 10, so that the inner liner 20 cannot move in the axial direction while rotating. In order to clean the material retained on the blocking portion 21, the inner liner 20 can be moved in the axial direction, and the structure of the adjustment groove 11 may be as follows:

referring to fig. 7, which is a schematic view of a material sliding pipe according to another embodiment of the present application, unlike the material sliding pipe in fig. 6, the extending direction of the adjusting groove 11 is deviated from the circumferential direction of the pipe body 10, so that one end of the adjusting groove 11 is close to the feeding port 13 of the pipe body 10, and the other end is close to the discharging port 14 of the pipe body 10. That is, the adjusting slot 11 is arranged in a spiral or spiral-like shape, and the lining pipe 20 can move along its own axial direction while the lining pipe 20 rotates, so that the material can slide off the blocking portion 21, and the lining pipe 20 can be cleaned.

Referring to fig. 5, in order to facilitate the rotation of the lining pipe 20, the material sliding pipe includes a rolling member 30 disposed between the lining pipe 20 and the pipe body 10. The rolling members 30 may be bearings, balls, or other members that facilitate rolling friction between the liner tube 20 and the pipe body 10, and an appropriate amount of lubricating oil may be filled between the liner tube 20 and the pipe body 10 to promote lubrication.

Preferably, the chute comprises a data acquisition device 40 for detecting at least one of the material flow, the speed and the impact force, wherein the data acquisition device 40 is arranged on the pipe body 10, and preferably, the data acquisition device 40 is arranged at a position close to the discharge port 14.

The rotation of the lining tube 20 may be arranged as a mechanically driven rotation in addition to the manual manner described above, in particular the chute comprises a driving device (not shown in the figures) connected to the lining tube 20 for driving the lining tube 20 in rotation. Further, in order to realize automatic control, the material sliding pipe includes a control unit (not shown in the figure) for controlling the driving device, and the control unit is electrically connected with the data acquisition device 40. The control unit can acquire the flow, speed and impact parameters collected by the data acquisition device 40 and automatically control the rotation of the lining tube 20 according to the change of the parameters.

A specific working process of the material sliding pipe is introduced below, in the working process, when the data acquisition device 40 monitors that the flow rate of materials in the pipe is greater than a set maximum preset value, feeding is suspended, the blocking portion 21 is rotated to the lower end, then feeding is started, the blocking portion 21 can play a certain blocking and buffering role on the materials (such as sand materials, powder materials and the like) passing fast, so that the flow rate of the materials is reduced, on one hand, the materials are prevented from generating large abrasion on the pipe wall, and on the other hand, the impact force of the materials at the discharge port of the material sliding pipe is prevented from being too large. Further, when the data acquisition device 40 monitors that the flow speed of the materials in the material sliding pipe is smaller than the set minimum preset value, feeding is suspended, the blocking portion 21 is rotated to the upper end, then feeding is started, the materials can smoothly pass through the material sliding pipe under the action of self gravity, and the blocking portion 21 does not play a blocking role. When materials (such as sand materials, powder materials and the like) conveyed by the material sliding pipe need to be switched from one material to another material, the blocking part 21 is rotated to the upper end, the materials accumulated by the blocking part 21 fall down and slide out of the discharge port 14 through the inner wall of the lining pipe 20 without the blocking part 21, the cleanliness of the inner wall of the material sliding pipe is ensured, and cross mixed pollution of two or more materials is avoided.

In order to facilitate the connection of the material sliding pipe, the two ends of the pipe body 10 are provided with flange pieces 12.
