Description

Technical Field

[0001] The utility model relates to the technical field of microbial fertilizer production, in particular to a pipeline exhaust device for a microbial fertilizer production line. Background Art

[0002] In the process of preparing and producing microbial fertilizers, liquid raw materials need to be transported to various tanks for process treatment. In the same and similar fields, there are many patent documents of this type. Referring to the Chinese patent with the authorization announcement number CN206014718U, the water-soluble fertilizer preparation device includes a reactor, a synthesis tower, a drying tower, a dust collector and a water washing tower, the reactor is provided with a feed inlet, and the reactor is connected to the synthesis tower through a first delivery pipe, the first delivery pipe is provided with a connecting valve, and a delivery pump (centrifugal pump) is also provided; the synthesis tower includes a pressure controller and a temperature controller arranged in the synthesis tower and a sampling device arranged outside the synthesis tower, and the synthesis tower is connected to the drying tower through a second delivery pipe, and a connecting valve is provided on the second delivery pipe.

[0003] During the pumping process, the liquid raw material often contains a certain amount of gas (often forming a large number of bubbles). During the transportation process, these air often cause damage to the liquid pump (for example, the bubbles mixed in the liquid cause "cavitation" on the surface of the high-speed moving impeller, destroying the impeller surface, causing damage to the impeller and leading to pump damage). Utility Model Content

[0004] The purpose of the utility model is to provide a pipeline exhaust device for a microbial fertilizer production line, which can very conveniently exhaust the gas in the feed pipeline of the liquid pump in time, improve the problems existing in the prior art, and also fully consider the problem of how to better collect the discharged liquid in the actual exhaust process.

[0005] The purpose of the utility model is achieved as follows: a pipeline exhaust device for a microbial fertilizer production line, comprising a liquid pump and a liquid infusion pipe connected to the inlet end of the liquid pump, the liquid infusion pipe bypasses an exhaust pipe, and is equipped with a collection bucket placed on the ground near the exhaust pipe, the upper end of the collection bucket is an open structure;

[0006] The exhaust duct includes a bypass hard pipe and a soft pipe. The bypass hard pipe is provided with a switch valve for controlling its opening and closing state. One end of the bypass hard pipe is fixedly connected to the infusion tube, and the other end is fixedly provided with a docking nozzle connected to its inner cavity. One end of the soft pipe is detachably mounted and connected to the docking nozzle. The soft pipe is bent so that the other end thereof extends into the collection barrel. The upper edge of the collection barrel supports the soft pipe, and the mounting position of the soft pipe and the docking nozzle is directly above the upper end opening of the collection barrel.

[0007] The beneficial effects of the utility model are:

[0008] 1. When the gas in the liquid needs to be discharged, the opening of the switch valve can be controlled, which can conveniently discharge the gas in the feed pipeline of the liquid pump in time to prevent the bubbles in the liquid from damaging the pump body;

[0009] 2. At the same time, full consideration is also given to the problem of how to better collect the discharged liquid during the actual exhaust process. A hose is used to discharge the liquid containing bubbles, and a special collection bucket is used to collect the discharged part. Full consideration is given to the possibility of leakage at the fitting position of the hose and the butt nozzle, so that the fitting position of the hose and the butt nozzle is directly above the upper opening of the collection bucket. Even if there is leakage at the fitting position of the hose and the butt nozzle, the liquid will drip into the collection bucket and will not drip onto the workshop floor.

[0018] The following will be combined with the attached embodiment of the present utility model Figure 1-8 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Embodiment 1

[0020] like Figure 1 , 4 As shown, a pipeline exhaust device for a microbial fertilizer production line is provided, including a liquid pump 2 and a liquid infusion pipe 1 connected to the inlet end of the liquid pump 2, the liquid infusion pipe 1 is bypassed with an exhaust pipe, and is provided with a collecting barrel 7 placed on the ground near the exhaust pipe, the collecting barrel 7 is a round barrel, and the upper end of the collecting barrel 7 is an open structure.

[0021] The exhaust duct includes a bypass hard pipe 3 and a soft pipe 6. The bypass hard pipe 3 is provided with a switch valve 4 for controlling its opening and closing state. One end of the bypass hard pipe 3 is fixedly connected to the infusion tube 1, and the other end thereof is fixedly provided with a docking nozzle 5 connected to its inner cavity. One end of the soft pipe 6 is detachably mounted and connected to the docking nozzle 5. The soft pipe 6 is bent so that the other end thereof extends into the collecting barrel 7. The upper edge of the collecting barrel 7 supports the soft pipe 6. The fitting position of the soft pipe 6 and the docking nozzle 5 is directly above the upper end opening of the collecting barrel 7. Once leakage occurs at the fitting position, the liquid can directly drip into the collecting barrel 7.

[0022] The above-mentioned hose 6 is configured as a telescopic circular hose and is made of a transparent material; since the hose 6 is a telescopic hose, it has a plurality of annular grooves along its length, and the upper edge of the collecting barrel 7 can be inserted into one of the annular grooves to complete the positioning of the hose 6.

[0023] When used on site, the hose 6 can be bent inwardly in a C-shape, and the portion extending into the inner cavity of the collection barrel 7 is inclined so as to guide the liquid to be discharged into the collection barrel 7 .

[0024] Embodiment 2

[0025] like Figure 2 , 5 As shown in , 6 and 7, another pipeline exhaust device for a microbial fertilizer production line is proposed, which is different from the first embodiment in that:

[0026] A. In order to better lock the position of the hose 6 and prevent the hose 6 from being displaced due to too fast a change in the liquid discharge speed, a positioning groove 7a with an upward opening is provided on the upper edge of the collecting barrel 7, and the hose 6 can be detachably inserted into the positioning groove 7a;

[0027] B. The infusion tube 1 is provided with a transparent observation window 101 for observing the bubbles in the liquid raw material. The transparent observation window 101 is close to the connection position between the bypass hard tube 3 and the infusion tube 1, that is, the bubbles in the infusion tube 1 during the infusion process can be observed at any time, which can be used as a reference for controlling the opening of the switch valve 4; if there are many bubbles, the switch valve 4 can be opened a little wider, and if there are fewer bubbles, the switch valve 4 can be opened a little narrower.

[0028] The above-mentioned solution of setting the transparent observation window 101 can be used in other embodiments.

[0029] Combination Figure 6 ,7 As shown, the setting scheme of the transparent observation window 101 is as follows:

[0030] The transparent observation window 101 includes a transparent window plate 101a, and an upwardly protruding positioning boss 102 is provided on the upper side of the tube wall of the infusion tube 1. The positioning boss 102 has a mounting hole connected to the inner cavity of the infusion tube 1, and then the transparent window plate 101a is fixed to the positioning boss 102 by screws, and sealed (the gap between the transparent window plate 101a and the positioning boss 102 is sealed with a sealing strip), and the mounting hole of the positioning boss 102 is covered / sealed with the transparent window plate 101a.

[0031] As an optimized structural design, the inner surface of the transparent window plate 101a is set as an inner arc surface 101b, which is aligned with the inner circumferential wall of the infusion tube 1 to ensure smooth flow of the liquid.

[0032] Embodiment 3

[0033] like Figure 3 , 8 As shown, another pipeline exhaust device for a microbial fertilizer production line is proposed, which is different from the first embodiment in that:

[0034] In order to better fix the position of the hose 6, a tube body guide assembly is provided on the upper edge of the collecting barrel 7. The tube body guide assembly is formed by a guide tube 8 and a movable seat 9 that are fixedly connected as a whole. The movable seat 9 is detachably connected to the upper edge of the collecting barrel 7. The guide tube 8 is arranged to be tilted downward, and its lower end is facing the inner cavity of the collecting barrel 7. The hose 6 movably passes through the guide tube 8 to extend into the collecting barrel 7.

[0035] The bottom of the movable seat 9 is provided with a bite groove 9a with an opening facing downwards, the vertical section of the bite groove 9a is an inverted U-shape, and the whole is an arc-shaped structure to match the arc-shaped edge of the collection bucket 7, and the bite groove 9a can relatively movably fit the upper edge of the collection bucket 7. In this way, the pipe body guide assembly can be flexibly adjusted along the upper edge of the collection bucket 7 to match the bending shape of the on-site hose 6.

[0036] In order to appropriately enhance the locking effect of the guide tube 8, an inner lining rubber sheet 10 is attached to the inner wall of the above-mentioned bite groove 9a, and the inner lining rubber sheet 10 is in contact with the surface of the collecting bucket 7. That is, the inner lining rubber sheets 10 on the two opposite sides of the inner wall of the bite groove 9a are respectively in contact with the outer wall and the inner wall of the collecting bucket 7, thereby forming a certain locking effect on the guide tube 8 and preventing the movable seat 9 from directly contacting the collecting bucket 7 and causing damage to the collecting bucket 7.
