Description

Discharge nozzle wear-resistant device for upper sand elevator
Technical field
This utility model relates to the configuration device field of chute, is specifically related to a kind of discharge nozzle wear-resistant device for upper sand elevator.
Background technology
When preparing dry-mixed mortar, need to be delivered in middle roll-over sand material by elevator, carry out follow-up being mixed with, existing upper sand elevator groove arranges a discharge nozzle on the top of elevator, the other end of discharge nozzle extend in middle roll-over, complete the conveying of sand, the discharge pipe of existing upper sand elevator generally uses metal material to prepare, during upper sand, sand material and discharge nozzle inwall continuous frictional, owing to the upper sand amount of every day is bigger, therefore the discharge nozzle transducer wall's abrasion of elevator is very fast, need often discharge nozzle to be keeped in repair and change, the most time-consuming take a lot of work, reduce work efficiency, wasting manpower and material resources again, simultaneously, owing to discharge nozzle is positioned at the position that comparison is high, need to carry out work high above the ground during maintainer maintenance, safety is low, maintenance cost is high.
Utility model content
The purpose of this utility model is to provide one can improve sand elevator discharge nozzle wearability, reduces loss, extends the discharge nozzle wear-resistant device for sand elevator in its service life.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows:
The base case that this programme provides is: a kind of discharge nozzle wear-resistant device for upper sand elevator, including elevator body and middle roll-over, described elevator body upper part is provided with discharge nozzle, described discharge nozzle is downward-sloping setting, described discharge nozzle lower end coordinates with middle roll-over, and described discharge nozzle is positioned at bottom the inwall of bottom to be removably connected with and is provided with multiple sand block groove.
Operation principle of the present utility model and have the beneficial effect that dry sand is transported to elevator bodies top by elevator body, middle roll-over is entered into then along discharge nozzle, the discharge nozzle inwall be positioned at bottom is provided with some sand block grooves, then it is being positioned at the sand of bottom during moving down along blow tank, the stop motion when moving in sand block groove or be positioned in the gap between sand block groove, forms a layer of sand.Then sand continues to move on layer of sand, avoids and wall friction in discharge nozzle with layer of sand friction.And in this utility model, sand block groove and discharge nozzle for removably connecting, then, when the abrasion of sand block groove is more serious, are pulled down the sand block groove of serious wear, are changed new sand block groove, and this device can be continuing with, and extends the service life of discharge nozzle.This utility model can improve the wearability of discharge nozzle, reduces loss, extends discharge nozzle service life.
Preferred version one: based on the preferred version of scheme, described sand block groove is curved, and arc is rounder and more smooth, and the layer of sand formed in making sand between each sand block groove gap and sand block groove is more stable.
Preferred version two: the preferably preferred version of, described sand block groove central angle is 100 ~ 180 °, if round angle is excessive, sand can be had some setbacks in moving process, if central angle is too small, then layer of sand is relatively thin, and abrasion resistant effect is bad.
Preferred version three: the preferably preferred version of two, the spacing between described adjacent sand block groove is 12 ~ 16mm, this spacing can make the sand between each sand block groove more closely, more stable.
Preferred version four, preferably two or the preferred version of preferred version three, described sand block groove material is metal, and Strength of Metallic Materials is higher, has stronger wearability.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation for the discharge nozzle wear-resistant device embodiment of upper sand elevator.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Reference in Figure of description includes: elevator body 1, discharge nozzle 2, sand block groove 3, middle roll-over 4.
Embodiment is the most as shown in Figure 1: a kind of discharge nozzle 2 wear-resistant device for upper sand elevator, including elevator body 1 and middle roll-over 4, elevator body 1 top offers discharge nozzle 2, and discharge nozzle 2 is downward-sloping setting.Wherein, discharge nozzle 2 is metal.Discharge nozzle 2 lower end is connected with middle roll-over 4, and discharge nozzle 2 is positioned at bottom inwall and has been bolted sand block groove 3.Sand block groove 3 is curved, and arc is rounder and more smooth, makes the sand between each sand block groove 3 gap more stable with the layer of sand of formation in sand block groove 3.Sand block groove 3 central angle is 140 °, if round angle is excessive, sand can have some setbacks in moving process, if central angle is too small, then layer of sand is relatively thin, and abrasion resistant effect is bad.Spacing between adjacent sand block groove 3 is 12mm, and this spacing can make the sand between each sand block groove 3 more stable.Sand block groove 3 material is metal, and Strength of Metallic Materials is higher, has stronger wearability.
Dry sand is transported to elevator body 1 top by elevator body 1, middle roll-over 4 is entered into then along discharge nozzle 2, discharge nozzle 2 inwall be positioned at bottom is provided with sand block groove 3, then it is being positioned at the sand of bottom during moving down along blow tank, the stop motion when moving in sand block groove 3 or be positioned in the gap between sand block groove 3, forms a layer of sand.Then sand continues to move on layer of sand, avoids and wall friction in discharge nozzle 2 with layer of sand friction.And in this utility model, sand block groove 3 and discharge nozzle 2 are for removably connecting, then when sand block groove 3 weares and teares more serious, pull down the sand block groove 3 of serious wear, change new sand block groove 3, this device can be continuing with, and extends the service life of discharge nozzle 2.
Above-described is only embodiment of the present utility model, and in scheme, the known general knowledge such as concrete structure and characteristic too much describes at this.Should be understood that; for a person skilled in the art, on the premise of without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim.
