Description

A wash structure that is used for prefab to produce line cloth district

Technical Field

The utility model belongs to the technical field of the prefab production facility, especially, relate to a washing structure that is used for prefab to produce line cloth district.

Background

CN201821667931.7 discloses a feeding system of a concrete spreader, which comprises an annular feeding frame with an annular track, a feeding cart located on the annular track, and a plurality of spreading racks disposed below the annular track of the feeding frame at intervals. Fig. 1 only shows the outer feeding section 31 of the annular feeding frame 3, the feeding frame 2 is located at the end of the annular track and is provided with a stirring station butt joint position for butt joint with the stirring main machine 4, the discharge hopper of the stirring main machine 4 of the stirring station is located right above the butt joint position, and the feeding port of the feeding car 5 can be butt joint with the discharge port of the stirring station at the stirring station butt joint position. In general, the mixing station bin 6 is located at one side of the end of the feeding frame where the mixing station is located, and raw materials in the mixing station bin 6 are fed into the mixing main machine 4 through the raw material conveying track. In order to reduce the occupied area, the stirring station is generally arranged to cross the annular feeding frame 3, the stirring host 4 is arranged above the upstream of the feeding section 31 outside the annular feeding frame 3, one or more material distribution frames 2 are arranged at the downstream of the feeding section 31 outside the annular feeding frame 3, and the feeding direction of the feeding section 31 outside the annular feeding frame 3 is the X direction as shown in fig. 1. After the concrete raw materials of the mixing plant are mixed in the mixing host machine 4, the concrete raw materials are discharged from the mixing host machine 4 to the feeding trolley 5 from the feeding hole, and then are transferred to the hoppers of the production line distributing machines through the feeding trolley 5 along the feeding direction of the annular feeding frame 3.

At present, a cleaning pool 7 is arranged in a material distribution area of a production line commonly used in the PC (concrete prefabricated part) factory building and used for washing a hopper of a material distributor, collecting cleaning sewage and precipitating concrete residues. The investigation finds that the existing PC production line has the following disadvantages in cleaning:

1) the existing cleaning tank has a single sedimentation structure, the heights of the bottoms of the cleaning tanks 7 are consistent, the design is too simple, incomplete concrete sedimentation is easily caused, and the sewage recycling rate is low;

2) because the precipitation area is too small, the precipitation time is long, the production beat and the production progress of a production line are influenced, and the production efficiency is low;

3) because of the too short length of the cloth frame, the cloth bucket moves to the end part of the cloth machine close to one end of the cleaning pool 7 and then can not be completely positioned right above the cleaning pool 7, so that the cleaning sewage can not be deeply fallen into the cleaning pool 7, and the problem of sanitation and dirt of a production line is easily caused.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome prior art not enough, provide a phenomenon that reduces to produce the indiscriminate splashing of line washing sewage, guarantee to produce the clear washing structure that is used for the prefab to produce line cloth district of line ground drying.

In order to solve the technical problem, the utility model discloses a following technical scheme:

the utility model provides a wash structure that is used for prefab to produce line cloth district, is including being located the setting tank group of cloth frame below, the cloth frame is in the orientation the orthographic projection of setting tank group direction covers the setting tank group.

The cloth machine frame is lengthened to cover the whole sedimentation tank group and the cloth station, when the cloth hopper of the cloth machine needs to be cleaned, the cleaning sewage and the concrete residues can be ensured to completely fall into the cleaning tank, and the cleaning sewage and the concrete residues are not splashed to a production line production area, so that adverse effects are caused on the ground and production line equipment.

As a further improvement of the above technical solution:

and the sedimentation tank group is arranged below one end of the material distribution rack close to the feeding section outside the feeding rack.

The sedimentation tank group comprises a primary sedimentation tank, a secondary sedimentation tank and a tertiary sedimentation tank which are sequentially communicated; and the third-stage sedimentation tank and the second-stage sedimentation tank are sequentially arranged along the feeding direction of the feeding section outside the feeding frame.

The first-stage sedimentation tank is located under the feeding frame, and the second-stage sedimentation tank and the third-stage sedimentation tank are both arranged on one side of the first-stage sedimentation tank close to the end part of the material distribution rack.

The length of the first-stage sedimentation tank along the feeding direction of the feeding section outside the feeding frame is greater than the sum of the lengths of the second-stage sedimentation tank and the third-stage sedimentation tank along the extension direction of the feeding frame.

The cloth frame is lengthened, the shape of the cleaning tank is improved, so that the phenomenon that the cleaning sewage of the production line splashes in a mess manner is reduced, and the floor of the production line is ensured to be dry and clean.

The bottom of the pool elevation H1 of one-level sedimentation tank is higher than the bottom of the pool elevation H2 of second grade sedimentation tank, the bottom of the pool elevation H2 of second grade sedimentation tank is higher than the bottom of the pool elevation H3 of tertiary sedimentation tank.

The H1 is + -0.000 m, the H2 is-0.500 m, and the H3 is-1.000 m.

The hopper cleaning sewage contains a large amount of concrete residues, and needs to be subjected to standing precipitation for a long time, so that solid concrete can be precipitated and separated from liquid water. The cleaning water after complete precipitation can be repeatedly used for cleaning the hopper, so that the cleaning water can be recycled. The three-stage precipitation mode increases the precipitation area of the concrete, improves the efficiency, optimizes the precipitation effect and reduces the occupation and waste of the cleaning link during production; in addition, the cleaning water precipitated by the three-stage cleaning tank can be repeatedly used for cleaning the hopper, the feed opening and the feeding trolley, so that the water resource is not wasted, and the purposes of saving and environmental protection are achieved. After the processes of drainage and fractional precipitation step by step, the cleaning sewage in the cleaning tank can be fully settled and precipitated, and the concrete is separated out to the greatest extent, so that the maximization of the precipitation function of the cleaning tank with the same area is realized.

Compared with the prior art, the utility model has the advantages of:

1. the cloth frame is lengthened, the shape of the cleaning tank is improved, so that the phenomenon that the cleaning sewage of the production line splashes in a mess manner is reduced, and the floor of the production line is ensured to be dry and clean.

2. The three-stage precipitation mode increases the precipitation area of the concrete, improves the efficiency, optimizes the precipitation effect and reduces the occupation and waste of the cleaning link during production;
