Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.

Referring to fig. 1, a salt dissolving barrel for hemodialysis water treatment includes a barrel body 1 and a barrel cover 2 covering the top of the barrel body 1, wherein the barrel body 1 and the barrel cover 2 are made of medical PE plastic material, and the prior salt dissolving barrel structure can also be adopted. The barrel cover 2 can be connected to the barrel body 1 in a direct buckling or threaded screwing mode, so that the interior of the barrel body 1 is kept relatively closed, and the interior of the barrel body 1 is prevented from being polluted by the outside. In the invention, all the parts are made of medical PE materials so as to meet the requirements of use standards.

The top of the inner wall of the barrel body 1 is detachably connected with a batch charging tray 3. As shown in fig. 3 to 5, the feeding tray 3 is a hollow disc structure with a convex center and a concave center, and the side wall of the feeding tray 3 is fastened on the inner wall of the barrel 1 by a locking screw 10. So, through changing the screw in length of locking screw 10 on throwing charging tray 3 lateral wall, can change the tight fixed external diameter size of charging tray 3 clamp to make charging tray 3 can possess certain commonality in the salt dissolving bucket of certain diameter within range, can realize fixed mounting in the salt dissolving bucket of multiple model.

A plurality of (8 as shown in fig. 4) plug connectors 301 which are uniformly distributed are arranged on the bottom surface of the batch pan 3, the plug connectors 301 are of a hollow cylinder structure and are positioned at the middle diameter of the batch pan 3, and the top end of the plug connectors 301 is communicated with the top surface of the batch pan 3. The inner diameter and the outer diameter of the plug 301 can be set according to the size of the feeding tray 3, and the inner diameter of the plug 301 is set to 10mm-30mm to fully meet the use requirement because the particle size of the granular salt (sodium chloride particles in this embodiment) is usually small. Because the middle diameter of the feeding disc 3 is of a concave structure, after solid particles are scattered into the feeding disc 3, the particles can automatically disperse and slide to a concave position, and then enter the plug-in connector 301 and naturally fall. In the process, the particle salt in the feeding disc 3 can be stirred by using objects such as a brush and the like in an auxiliary manner, so that the particle salt can completely and smoothly enter each plug-in connector 301.

A plurality of (8 in this embodiment) blanking barrels 4 are fixedly connected to the bottom of the batch pan 3, as shown in fig. 2 and 11. The blanking barrel 4 is a hollow thin-wall cylinder, the inner diameter of the blanking barrel is the same as or slightly larger than that of the plug 301, and the top end of the blanking barrel is vertically and fixedly connected to the outer side of the bottom of each plug 301 in a fastening and plugging or threaded connection mode, so that the blanking barrel 4 is communicated with the top of the feeding disc 3, the granular salt falling into the plug 301 can continue to fall down naturally from the blanking barrel 4, and the granular salt cannot directly fall into the barrel body 1.

The outer side of each charging hopper 4 is movably sleeved with a feeding hopper 5, as shown in fig. 2. The feeding barrel 5 can vertically slide on the outer side of the blanking barrel 5 to realize lifting. The lengths of the feeding cylinder 5 and the blanking cylinder 4 are about half of the height of the barrel body 1, and the maximum lifting distance of the feeding cylinder 5 is about half of the height of the barrel body 1.

At the beginning, because the weight of the granular salt in the storage basket 9 is the largest, the density of the injected clean water is smaller, the buoyancy is not enough to suspend the storage basket 9, the storage basket 9 is immersed in the water, the granular salt in the storage basket 9 is contacted with the water in the largest area to realize block instant dissolution, the solubility of the solution is gradually increased and the density is gradually increased along with the gradual dissolution and weight reduction of the granular salt, the storage basket 9 starts to float upwards until the solution reaches a saturated state, the granular salt cannot be dissolved continuously, and the storage basket 9 is suspended on the liquid level; when the saturated solution in the barrel body 1 is partially extracted and the liquid level is lowered, the storage basket 9 is lowered synchronously along with the liquid level; when the clean water body is replenished into the barrel body 1 again, the density of the solution is reduced, and the storage basket 9 gradually sinks again until the solution reaches the saturated state again and is suspended again to the liquid level of the saturated solution. Thus, the granular salt in the storage basket 9 can be continuously and automatically dissolved, the granular salt and the saturated solution can be in a separated state, and the saturated saline water in the barrel can be completely discharged without carrying undissolved granular salt.

The center of the batch pan 3 is movably sleeved with a liquid injection cylinder 6, and the outer side of the liquid injection cylinder 6 is movably sleeved with a lifting cylinder 7, as shown in fig. 2, 10 and 11. A hollow connecting column 302 is arranged at the center of the batch pan 3, the top end of the liquid injection cylinder 6 is sleeved in the hollow connecting column 302 in an empty mode, a flanging is arranged on the edge of the top of the liquid injection cylinder 6, and the flanging is erected on the top surface of the hollow connecting column 302; the water injection joint 601 is in threaded connection with the outer side of the top of the hollow connecting column 302, and the water injection joint 601 fixes the flanging of the liquid injection cylinder 6 on the top surface of the hollow connecting column 302, so that the liquid injection cylinder 6 is fixed on the batch charging tray 3. The top of the water injection joint 601 may be connected to an external water supply device (e.g., a water pipe) to supply clean water in the tub 1. Obviously, the plug 301 on the feeding tray 3 can also supply water to the barrel body 1, and simultaneously can wash the inner walls of the blanking barrel 4 and the feeding barrel 5, so as to prevent the granular salt from attaching to the inner walls of the blanking barrel 4 and the feeding barrel 5. Preferably, the through-hole has been seted up at bung 2's top surface center, and the through-hole internalization is pegged graft and is had rubber buffer 201, and under normal condition, rubber buffer 201 is located bung 2 in order to guarantee the inside leakproofness of staving 1, when needs are to the moisturizing in staving 1, can shift out rubber buffer 201 from bung 2, makes water injection joint 601 expose in the through-hole, can connect 601 lug connection with the water injection with outside water supply equipment through the through-hole, accomplishes the moisturizing process under the condition of not opening bung 2.

The material pressing plate 8 is fixedly connected to the bottom end of the lifting cylinder 7, the material pressing plate 8 is arranged on the inner side of the hollow storage basket 9, and particle salt in the storage basket 9 is pressed below the material pressing plate 8. As shown in fig. 6 and 7, the blank holder 8 is composed of a bottom plate 806, a top plate 804 above the bottom plate 806, and a plurality of spiral wall plates 805 uniformly distributed around the axis thereof between the bottom plate 806 and the top plate 804. The spiral direction of each spiral wall plate 805 is the same, a spiral channel 801 is formed in the space between two adjacent spiral wall plates 805, the top plate 804 and the bottom plate, and a water inlet 802 communicating the spiral channel 801 and the lifting cylinder 7 is formed in the center of the top surface of the pressure plate 8. The bottom mounting of section of thick bamboo 7 bonds in the top of water inlet 802 for annotate liquid section of thick bamboo 6, the spiral channel 801 intercommunication of section of thick bamboo 7 and pressure flitch 8 is gone into by annotating liquid section of thick bamboo 6 and then get into behind the pressure flitch 8 in the lifting cylinder 7, the water is under spiral channel 801's guide effect, to the dispersion outflow all around of pressure flitch 8, the liquid of outflow gets into in the storage basket 9, get into staving 1 by the hole 902 that permeates water again, the in-process once more, the water that flows can be tentatively contacted with the granule salt and accomplish fast dissolving. Meanwhile, under the reverse acting force of the water flow, the pressure plate 8 is pushed to rotate around the axis of the pressure plate, and in the rotating process, the pressure plate 8 can further flatten and roll the particle salt below the pressure plate, and disturb the particle salt on the surface layer to promote the dissolving process.

Preferably, the overall density of the pressure plate 8 is greater than that of the saturated sodium chloride solution, so that in any state of the solution, the pressure plate 8 acts on the top of the particle salt in the storage basket 9, and the particle salt cannot be disturbed and scattered randomly and falls into the barrel body 1 from the water permeable holes 902; meanwhile, the whole height of the granular salt in the storage basket 9 can be kept consistent through the extrusion effect, and the granular salt is prevented from being locally accumulated. Further preferably, the bottom surface of the pressure plate 8 is uniformly distributed with a plurality of raised strips 803 arranged along the radial direction of the pressure plate around the axis thereof, so that the top surface of the granular salt can be rolled and flattened by the raised strips 803 during the rotation process of the pressure plate 8. Therefore, when the feeding disc 3, the discharging barrel 4 and the feeding barrel 6 are used for supplying the granular salt in the storage basket 9, the water injection connector 601 needs to be temporarily removed from the feeding disc 3, the liquid injection barrel 6 is manually moved upwards, and the pressure plate 8 is lifted to the highest position in the storage basket 9 through the lifting barrel 7, so that the bottom surface of the pressure plate 8 is located above the feeding hole 901, and the granular salt fed from the feeding hole 901 is accumulated below the pressure plate 8.

Because staving 1 adopts opaque PE material to support, the inconvenient height of observing the interior liquid level of staving 1 in the outside of staving 1, more inconvenient surplus of knowing the interior granular salt of staving 1, for this reason, this salt dissolving bucket adopts the surplus of reflecting the interior granular salt of storage basket through the position change of pressure flitch in the storage basket, be convenient for in time and carry out the replenishment of granular salt with the ration, the water level of saturated solution in the salt dissolving bucket is reflected through the position change of storage basket in the salt dissolving bucket, so that in time carry out the replenishment of clean water. Specifically, as shown in fig. 2, 10 and 11, the top of the material storage basket 9 is integrally provided with a guide sleeve 903 sleeved outside the lifting cylinder 7, the top of the outer wall of the guide sleeve 903 is fixedly sleeved with an annular first lamp holder 14, the first lamp holder 14 is provided with a horizontally arranged first laser lamp 10, the outer wall of the top of the lifting cylinder 7 is fixedly sleeved with an annular second lamp holder 15, and the second lamp holder 15 is provided with a horizontally arranged second laser lamp 11.

When the storage basket 9 is located at the lowest position inside the barrel body 1, the position, corresponding to the light spot, of the light spot emitted by the first laser lamp 10 on the barrel body 1 is the zero position of the liquid level, when the storage basket 9 rises or falls along with the liquid level, the light spot correspondingly rises or falls, and the height difference between the light spot position of the light of the first laser lamp 10 and the zero position is approximately equal to the height of the liquid level of the solution at present. When the amount of the particle salt in the storage basket 9 reaches the maximum, the pressure plate 8 is located at the highest position in the storage basket 9, and the vertical distance h between the first laser lamp 10 and the second laser lamp 11 is the maximum.
